Our behavioral data indicate that environmental change in Amboseli has profoundly influenced the time budgets, social lives, diet, and habitat use of baboons. During periods of woodland die-off, baboons experienced both low fertility and high infant mortality [159]. They also devoted nearly 80% of daylight hours to foraging and dramatically reduced their social time, in spite of both theoretical and empirical evidence indicating that they attempt (and often succeed in) conserving social time as a means of servicing their crucial social relationships [167]. A widely accepted and influential model of baboon ecology predicted that social groups will lose cohesion and either fission or go extinct under extreme environmental stress [Dunbar 1992], our data do not support this model. Rather, the baboons modified their diet by increasing the diversity of food items; they also moved to completely new home ranges in areas of Amboseli with intact woodland. Survival and fertility increased following these ...

One of the unfortunate aspects of aging is tooth wear. Depending on your diet, years of biting and chewing can cause enamel along the biting surfaces to erode. Your body also cant replace enamel - so when it comes to teeth its not a question of if, but how much your teeth will wear during your lifetime.. To make matters worse, certain conditions cause tooth wear to accelerate. Teeth softened by acids or tooth decay, for example, erode faster than healthier teeth. So will grinding habits: often fueled by stress, these include chewing on hard items like nails, pencils or bobby pins.. You may also grind your teeth, usually while you sleep. Normal biting and chewing produces pressure of about 13 to 23 pounds per square inch: grinding your teeth at night can well exceed this, even up into the hundreds of pounds.. There are some things we can do to alleviate these issues. For clenching and grinding habits, one primary step is to address stress through counseling or biofeedback therapy. For nighttime ...

This is the largest wolf skull in our collection. Based on tooth wear we assume that it is from a very old individual. The upper canines are significantly worn down and some tooth loss had occurred during life. Bone loss associated with a missing tooth is clearly visible on the left view. The tooth wear can best be viewed by zooming in on the ventral view; for several teeth the wear extends through all layers into the pulp cavity. Wolf12092001 serves as an interesting comparison to a far younger wolf with nearly intact dentition. ...

The work was carried out by a University of Bristol student, working with an international team of researchers. The research was published online in Quaternary International.. Today, elephants live only in remote, tropical parts of Africa and southern Asia, but before the Ice Ages they were widespread.. As his undergraduate research project, Zhang Hanwen, MSci Palaeontology and Evolution graduate and now PhD student at the University of Bristol, undertook cutting-edge analysis of fossilised elephant teeth from China.. In a collaboration with the University of Leicester, and the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, where the fossilised teeth are curated, Hanwen sampled 27 teeth for tiny wear patterns called microwear.. We are talking huge, brick-sized molars here - the largest of any animal, said Hanwen, but the signs of tooth wear are tiny, down to thousandths of a millimetre. However, these microscopic surface textures can tell us whether they were eating ...

The retromolar space (RMS), defined in paleoanthropology as a space posterior to the third molar, between the distal edge of the tooth and the anterior margin of the ascending ramus when the mandible is held in lateral view, has been described as an autapomorphic trait unique to Neandertals despite its presence in anatomically modern humans (AMHs). This study examined RMS prevalence in a sample of Protohistoric Arikara and Mandan Amerindians to determine what craniofacial morphology is correlated with the RMS. It was hypothesized that the feature would be present in the Amerindians studied and associated with a long cranial length, a large nasal height, midfacial prognathism, a broad mandible, and dental wear. The results indicated that RMSs were present in the Arikara and Mandan and significantly correlated with cranial length, cranial breadth, nasal height, bizygomatic breadth, basion-nasion length, basion-nasiospinale, mandible length, gonial angle, bigonial breadth, and dental wear. Thus, ...

Tooth enamel isnt just strong; its the hardest substance in your body. It isnt indestructible, however, and can be eroded by substances that are stronger. Acid exposure can come from many sources, but with the help of your dentist, you can keep your enamel strong and healthy.. Symptoms. Acid erosion on teeth can lead to a variety of symptoms that should be evaluated by a dentist. As the outer layer of your teeth wears away, you may experience tooth sensitivity. This sensitivity often leads to pain when you consume hot or cold foods and drinks.. Your teeth may also become discolored. This is because the enamel is white, unlike the sensitive, yellow tissue underneath is known as dentin. As the enamel erodes and exposes more of your dentin, your teeth begin to show more of its yellow color.. The appearance of your teeth can change in other ways as a result of acid erosion, depending on the case. The bottom edge of your front teeth may start to look transparent instead of its natural opaque. You ...

Thanks for the suggestions. Actually Im more concerned with finding a shoe to use in my BQ attempt this Fall. What Im looking for is a light weight trainer with forefoot cushioning and medial support. I spoke with the Puma rep at the Columbus marathon expo and tried on the COMPLETE PHASIS. You mentioned wear pattern, with my orthotics almost all the wear is in ball of my foot continuing to the very outside of shoe. There is little wear on the toe and heel and almost zero wear on the medial side.. With the orthotics correction and my ball / heel foot strike I wonder if I even need a motion control shoe like the SupreNova Control because Im bypassing all the MC devices with my foot strike. Is my wear pattern normal, and are the orthotics over-correctioning my over-pronation? He felt that I might benefit form the COMPLETE PHASIS- a neutral, light weight trainer. That it might be a good marathon shoe for me. Thanks. ...

Teeth grinding is one childhood habit that sounds worse than it usually is: often the most harm done is to your nights sleep. That said, though, its still a habit to keep your eye on.. Also known as bruxism, teeth grinding is so common among children that its considered normal behavior by many healthcare professionals. As for causes, some suggest a childs immature neuromuscular chewing control may trigger it, while others point to the change from deeper sleep to a lighter stage as a possible cause. Problems like airway obstruction, medications or stress also seem to contribute to the habit.. For most children, teeth grinding usually fades by age 11 with no adverse effect on their teeth. If the habit extends into adolescence, however, theres an increased risk for damage, mainly tooth wear.. This can happen because grinding often produces chewing forces 20-30 times greater than normal. Over time this can cause the biting surfaces of the teeth to wear and reduces the size of the teeth. While ...

Along with thumb sucking, childhood teeth grinding is one of the top concerns anxious parents bring to their dentists. Its so prevalent, though, many providers consider it normal behavior-the sleep-disturbing sound it can generate is often the worst consequence for the habit.. But that doesnt mean you should brush aside all concern, especially if the habit continues into late childhood. Long-term teeth grinding could eventually damage the teeth and gums.. Teeth grinding (or clenching) is the involuntary movement of the jaws when not engaged in normal functions like chewing, speaking or swallowing. The action often produces higher than normal chewing forces, which over time can accelerate tooth wear, cause fractures, or contribute to loose teeth, all of which could increase the risk of dental disease. While it can occur at any time its most common among children during nighttime sleep.. While stress is the usual trigger for teeth grinding in adults, with young children the causes for the habit ...

Conclusion. The pathological changes indicated the cause of death to have been poisoning. The changes are characteristic of Amitraz. This is a very common poison available in all agrovet shops and is suspected to have been used in this case. The fact that a lion with similar pathological changes died at the same time and within a radius of about 100meters, indicates that the two animals must have fed on the same poisoned bait.. The presence of offals within the same area indicates that the culprits may have used the offals for poisoning the animals.. CASE#5 AN ELEPHANT INJURED DURING HUMAN WILDLIFE CONFLICT.

If you have been in practice long enough, you will have run into something like this eventually. This is a 76 year old farmer who has fairly obviously been grinding his teeth. In fact, you would be making a correct assumption. Note that the tooth wear is much worse anteriorly than it is in the posterior. As we will eventually see, this is diagnostic of abrasion from bruxism. But notice a few other less obvious things. You see no occlusal amalgam fillings in the posterior teeth. You see no plaque or redness around the gingiva. You see no active decay anywhere. Furthermore, the patient has no periodontal bone loss in spite of a serious bruxing habit. On the other hand, you do see a few buccal composite fillings along with severe buccal-cervical wear. We can conclude the following from these observations:. This patient has probably never used too much sugar. We conclude this by the lack of amalgam fillings in the intact molars and the occlusal of #4, the one surviving premolar.. The patient has ...

With their teeth constantly growing throughout their lifetime, daily chewing activities to wear the teeth down is a necessity for guinea pigs. Timothy or alfalfa hay is rich in silicates that will help teeth wear naturally. Chew toys should also be provided in the form of cardboard tubes, boxes or wooden blocks.

The rhynchosaur Hyperodapedon gordoni from the late Triassic of Elgin, northeast Scotland, was a squat 1.3 m long reptile with a specialized skull. The partial remains of about 35 individuals were studied largely from casts. There is a broad size range (? age), and two morphs may be distinguished on the basis of proportions (? sexual dimorphism). Hyperodapedon had a large nasal capsule and a large eye with sclerotic plates. These indicate a good sense of smell and diurnal vision. There was no tympanum, but Hyperodapedon could probably detect sound via skin behind the quadrate, and via its throat and large hyoids. Evidence from the jaw articulation and tooth wear shows that Hyperodapedon had a precision-shear bite. Food was probably scraped up with the premaxillary beak and manipulated by a powerful tongue. The batteries of teeth on maxilla and dentary retained open roots throughout their functional life with no normal reptilian replacement. The hindlimb was adapted for scratch-digging, from a ...

If you cannot afford to get a proper gait analysis completed, having someone observe you on a treadmill from behind will give you an idea if you are an overpronator. It is possible to tell without observing directly whether you are likely to be an overpronator by looking at your foot arches. Check your foot arch height by standing in water and then on a wet floor or piece of paper which will show your footprint. If your footprints show little to no narrowing in the middle, then you have flat feet or fallen arches. This makes it highly likely that you will overpronate to some degree when running. If you have low or fallen arches, you should get your gait checked to see how much you overpronate, and whether you need to take steps to reduce the level to which you overpronate. Another good test is to have a look at the wear pattern on an old pair of trainers. Overpronators will wear out the outside of the heel and the inside of the toe more quickly than other parts of the shoe. If the wear is quite ...

The best way to determine what shoes will best fit YOUR needs is to go to a running shoe store and have an expert look at your form and match you up. I bring the socks I like to run in and my old shoes so they can see the wear pattern. The spots that wear most will reveal where the foot is striking the ground and what kind of runner you are for a shoe match. In Richmond, I have been to both Lucky Foot and Three Sports with really good service, expertise and results in matching me up with the right shoe. Run in the shoes. Ask questions. Plan to stay a while so the search is relaxing. I also like to find deals just before the latest model is released each year. Once I have a brand/type and series I am confident in, I commit to it & look online for deals to replace it with the same model. My shoes last longer when Im not running in the same pair every day so Im not buying many at once. I will just own many at once for parallel use. The life of the shoe depends on how many miles you put into ...

Herein, we developed a live molding technique to allow repeated measures testing of ungulate microwear to reduce the number of subjects needed for feeding trials. We also present a robust computational method for comparing treatments and quantifying observer error. In general, our method is successful, repeatable, and can be used as a guideline for future microwear studies regardless of whether they include a controlled feeding component. Overall, our methods compensate for any repeatability differences among current microwear methods. Furthermore, we used our methods to directly assess the contribution of fine- and medium-grained dietary grit to tooth microwear formation in sheep and found that exogenous dietary grit of this size results primarily in the formation of pits on the enamel occlusal surface.. Our system of introducing grit treatments was particularly effective; sand adhered to the hay and the sheep found the corn syrup-sand mixture palatable, as confirmed by LOI analysis of feces. ...

Wear OS has forever been on the struggle bus. It has failed for years to improve upon a smartwatch experience that has fallen behind almost every single smartwatch player it needs to compete with, namely Samsung and Apple. While there are still Wear OS partners who make watches, the feature set for them hasnt grown, particularly in the area of health, which is where smartwatches and wearables have started to take a focus.. In a new survey rolling out through the Google User Experience Research program, Google is asking participants for feedback on how they can improve Wear OS. The survey is heavily focused on health tracking, from sleep metrics to SP02 tracking to automatic detection of a variety of categories to pairing with medical equipment. While this doesnt mean we are guaranteed to see Google finally step up the Wear OS game in health, its almost a given that they have to. After all, they did just buy Fitbit.. The survey was broken out into pages with two questions, one about how you ...

Gradually, this small service grew, extending its service to civilians and so not only more army doctors had to be recruited but also civilian doctors were asked to join. The backbones were British doctors in the senior post and Syrian doctors in the junior posts. By 1955, they were all replaced by Sudanese doctors. These pioneers had to work under difficult conditions and quite often had to do additional work unrelated to their training. As a result of their experiences and cumulative hard work over the years, they made a slow but steady progress. This paper is meant to give a broad outline of the events through which modern surgery in the Sudan passed; to acknowledge the debt we owe to those pioneers who paved the way for our present medical service and medical training; and to remind our young doctors that medical history, like that of all arts and sciences, is continuous.

That depends on a lot of different factors. SD cards are not required to have wear leveling at all. Most name brand cards have wear leveling built in, but a lot of the cheaper knockoffs dont. The OS has some control over how thats done, but not really in the way youre hoping for. If you dont expand the logical disk, the OS wont ever write outside of the area its defined. That has to be left to the devices firmware for a variety of reasons.. I would recommend expanding the file system, since you dont really lose anything by doing so. The cloned image may take significantly more space on disk, but compressing it with 7z, or something similar will greatly reduce that effect.. Alternatively, you could backup using means other than a full system clone.. ...

Approximately 60% of patients presenting to dentists with erosive tooth wear have significant gastroesophageal reflux (GERD), despite minor reflux symptoms. No longitudinal studies of reflux-associated erosive tooth wear and of reflux characteristics have been reported to date. The aim of this study was to characterize the longitudinal course of GERD and of associated erosive tooth wear, as well as factors predictive of its progression, in a large group of patients. Seventy-two patients presenting to dentists with clinically significant erosive tooth wear and increased esophageal acid exposure by 24-h multichannel intraluminal pH-impedance measurement (MII-pH) were re-assessed clinically and by MII-pH after 1 year treatment with esomeprazole 20 mg twice-daily. Predictive factors for erosive tooth wear were assessed by logistic regression. At follow-up, no further progression in erosive tooth wear was observed in 53 (74%) of patients. The percentage of time with a pH | 4, the number of acid reflux

The aim of the study was to evaluate the prevalence and severity of erosive tooth wear (ETW) and its association with dental caries and the use of psychoactive substances among Finnish prisoners. One hundred voluntary prisoners (90.9%) from the Pelso Prison participated in this cross-sectional clinical study between September 2014 and February 2015. Fifty prisoners were also interviewed using the one-on-one interviewing technique for their background factors and use of psychoactive substances. Basic Erosive Index (BEWE) (0-18) was used to measure erosive tooth wear. Decayed (D), missing (M), filled (F) and the number of remaining teeth (T) and DMFT were reported. The association between the different variables was tested and analysed by using cross tabulation. To test the association between the variables a logistic regression analysis was conducted. Almost all (90%) of the subjects had need for preventive and operative treatment for ETW. In addition, one in five (19%) suffered from severe erosive tooth

No Preparation Veneers. One of the very latest techniques to emerge has been the no preparation veneer. Advances in porcelain technology allow dental technicians to make extremely thin porcelain veneers that can be bonded to teeth without any tooth removal being required.. At Ravat & Ray Dental Care we offer no preparation veneers as part of our comprehensive range of treatments. Our highly trained dentists can discuss these with you as part of your custom treatment plan.. Obviously it is a good thing not to have to remove tooth tissue; however as this is a very new technique there are no longer term scientific studies to show what the long term survival of these veneers is.. Palatal Veneers. This specialised treatment is one option for the management of tooth wear which mainly affects the palate side of your upper front teeth. Tooth wear of this kind can often be due to acid erosion and can occur as a consequence of illnesses such as bulimia or acid reflux. It is vital that the cause of the ...

Entelodonts are known to have lived from the late Eocene until the early Miocene in China, Europe, and North America. Other animals in their environments filled apex predator niches, including cat-like nimravid sabertooths, amphicyonids (bear-dogs), and hyaenodontid creodonts. The extent to which entelodonts were predators is debated, however, wear patterns on entelodont teeth do resemble modern carnivorans in some respects, and the later and larger species have binocular vision. There is also evidence of entelodonts caching the bodies of early camelids as a food source,[17] as well as multiple examples of toothmarks on bones. Entelodonts were among the largest animals in their environments and could easily exploit any available food. Analysis of their dentition shows both very high jaw strength and extreme tooth wear. Their front teeth interlocked, so they could not have cropped grass. The oddly expanded semi-circular forepart of the skull, specific to this group and Andrewsarchus and similar ...

The second most common cause of tooth wear is toothpaste abuse. As you may recall from the first page in this series, toothpaste abuse does NOT mean using too much toothpaste on the brush. It means using toothpaste in conjunction with very aggressive, prolonged, frequent, and hard brushing using a wide, back and fourth, sawing motion with the brush. This is most frequently done by patients on the occlusal and buccal surfaces of the teeth, and less aggressively on the lingual surfaces. This is a very common problem and is often engaged in by patients who do not like the color of their teeth and want to whiten them in the mistaken belief that aggressive use of the toothbrush/toothpaste will accomplish this.. Early research has shown that the toothbrush itself does not damage the teeth without additional abrasive, in spite of aggressive brushing. However, the addition of abrasive in the form of toothpaste DOES abrade away tooth structure. This is a bit like a lab rag wheel on a dental lathe. The ...

Although elephant families are led by matriarchs, they are not autocratic. Decisions to stay with or leave family members depend on a variety of factors, including the availability of food and the particular elephants in question. Each female is free to leave her family unit and go off by herself. Its rare for this to happen in Amboseli, and usually lone females are either ill or in oestrus, when they get separated from their families whilst being pursued by keen males. Much more common is that families break down into smaller units composed of sisters, or mother/daughter pairs, with their dependent calves alongside. This happens when females disagree about where or how to spend their day, and is much more common in certain families than others.. Decisions about where to go are usually made by a process of consensus within the family. A resting family will usually be grouped around sleeping calves.

The DSWT rangers reported to have spotted a male elephant with a suspected arrow injury to the left hind quarters. Having come in from Amboseli and aided by the Trusts aircraft, a thorough search ensued. The elephant was finally spotted in thick bush in the midst of its family.. Immobilization, Examination and Treatment. The elephant was immobilised with 18mg Etorphine in a 3 ml Dan - inject dart using the Dan Inject system from a Helicopter. Unfortunately, the elephant went down to a sternal position in between thick bush after 8 minutes and was quickly flipped over to lateral recumbence using a landcruiser. The trunk was maintained patent using a piece of stick placed across the nostril entrances. Plenty of water was doused on the elephant to keep the body temperature low and the ears used as blindfold.. On physical examination the elephant ...

Nearly one-fourth of all the bones in your body are in your feet. A broken (fractured) bone in your forefoot or in one of your toes is often painful, but rarely disabling. Most of the time, these injuries heal without operative treatment.. There are two types of foot fractures: stress fractures and general bone fractures. Stress fractures usually occur in the bones of the forefoot extending from the toes to the middle of the foot. Stress fractures are like tiny cracks in the bone surface. They can happen with sudden increases in exercise (such as running or walking for longer distances or times), improper training techniques, or a change in surfaces.. Most other types of fractures extend through the bone, and are called bone fractures. They may be stable, in which there is no shift in bone alignment, or displaced, in which the bone ends no longer line up properly. Bone fractures usually result from trauma, such as dropping a heavy object on your foot, or from a twisting injury. If the fractured ...

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition - through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentists office. In fact, Shields posted the photo to her own Instagram account, with the caption More dental surgery! I grind my teeth! And judging by the number of comments the post received, shes far from alone.. In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like ...

Tarsiers are among the smallest haplorhine primates (80-150 g), and their diet is based on insects and other small animal prey [27]. Tarsius sirindhornae was a large species of Tarsius, as large as or possibly larger than T. bancanus, the largest extant Tarsius. We used the regression equation of the M1 area against body weight proposed by Gingerich [28] for Tarsius and obtained an estimated body weight of T. sirindhornae of 90-180 g. Its body mass places it below Kays threshold of 500 g, below which primates cannot be obligate folivores owing to fundamental metabolic constraints [29]. Some specimens of T. sirindhornae display a high degree of premolar and molar wear with horizontal wear facets, suggesting a dietary difference from most other tarsiers. Its large premolars and molars, with enlarged M3 and low and less acute molar cusps, also point towards a less insectivorous and carnivorous diet than the extant and fossil Tarsius and even other fossil Tarsiidae. The meaning of such an odd ...

The plaque consists of bacteria and saliva that collects on the surface of the teeth. By depositing plaque around the tooth neck (the place where the tooth and gums touch) the gums become inflamed and gingivitis is created. Some of the plaque bacteria are harmful and can cause gum disease. The plaque can become solid (mineralized) and turn into a solid deposit or calculus (calculus, tartar). The present bacteria continue to damage further tissue that supports the root of the tooth.. Prevention of the periodontal diseases is in proper maintenance of oral hygiene and regular checks by the dentist / periodontist. Gingivitis can affect anyone at any age and is naturally the least desirable with young people and children.. Teeth clenching make it difficult to clean them, which leads to caries and periodontal disease. Improper bite affects the jaw joint and the uneven distribution of forces on the teeth, irregular tooth wear, all of which have a detrimental effect on the gums and the supporting tissue ...

Common concerns such as worn or chipped teeth, recurrent headaches, neck, shoulder or upper back pain, pain in the jaw joint and grinding or clenching of your teeth may be an indicator for chewing system disharmony. In this case, Bioesthetic Dentistry is probably able to help you.. Unlike many other treatment approaches, Bioesthetic Dentistry diagnoses the cause of tooth wear and other chewing system disharmony instead of focusing on the symptoms. A thorough investigation of your tooth positions and the way your teeth fit and work together (occlusion) and the functioning of your jaw joints (temporomandibular joint) forms the basis for any diagnosis and treatment. The goal is to establish a perfect harmony between all parts of the chewing system and restore your teeth to their optimal shape and relationship - resulting in a healthy, highly functional, unworn and beautiful smile.. Dr. Casacci is an accredited Bioesthetic Dentist with the knowledge and techniques to treat proactively toward a ...

Many people receive orthodontic treatment to fix their crooked teeth, but braces can also resolve bite issues, as well. Braces are great ways to fix misaligned jaws in children and adults and help prevent the consequences of underbites and overbites. Misaligned jaws are often painful and obvious, and many children are unfortunately teased by their peers because of it. Our bite refers to how the upper and lower teeth meet together, which influences how we chew, eat and speak. The two most common bite problems are an underbite and overbite, with an underbite occurring whenever the lower jaw sits in front of the upper jaw while the overbite happens when the upper jaw protrudes abnormally over the lower jaw. While these deformities look awkward, they have consequences that are more serious than aesthetic concerns. Underbite create a bulldog appearance as the lower jaw protrudes out, which not only puts a lot of stress on the joints but also causes tooth wear. Overbites create buck teeth that stick ...

Study of Labidosaurikos meachami, from the Lower Permian Hennessey Formation (Sumner Group) of north-central Oklahoma, reveals the presence of over thirty new cranial characters not present in single-tooth-rowed captorhinids and Captorhinus aguti. However, it is uncertain if these new characters represent autapomorphies of L. meachami because the skulls of all other large, multiple-rowed captorhinids are poorly known; many of these characters may instead diagnose subclades of multiple-tooth-rowed taxa within Captorhinidae. A suite of skeletal features, including the presence of tooth plates, prominent tooth wear, and the morphology of the skull roof, suggests strongly that L. meachami was herbivorous. Propaliny was probably a significant component of the feeding mechanism.Phylogenetic analysis of the interrelationships of the well known North American captorhinids indicates that Labidosaurikos meachami is more closely related to the large, single-rowed Labidosaurus hamatus than it is to ...

Erosive wear takes place when hard solid particles impact on a surface (Tilly 1977 Hutchings 1992 Charles et al. 1997) and material loss due to erosion E is measured as the ratio of the mass of removed material with respect to the mass of erosive particles. Erosive wear is due to the impact of hard particles on surfaces. The erosion processes and erosive wear depend on the impact angle Factors affecting the rate of wear Hardnessparticles with hardness lower than the surface cause little wear. Shape- angular particles cause greater wear than rounded particles. Sizelarger particles cause more extensive wear as they carry more kinetic energy Impact speed (for erosion)particles with greater speed cause more extensive wear as they carry more kinetic energy..

Effects of wear and member flexibility on the dynamic performance of a planar five-bar mechanism with joint-clearance are investigated. The equation of motion of the mechanism is derived based on the absolute nodal coordinate formulation (ANCF). In order to enhance the accuracy of the contact force, the slope of the load-displacement curve of the cylindrical joint with clearance is used. The contact deformation couples the joint wear to the contact state. The contact force model of Flores and coworkers is improved, by the introduction of the stiffness coefficient. The wear depth is predicted by using the Archards wear model. Simulations show that the multiclearance joints can generate stronger contact forces relative to single clearance joint case. This leads to more severe wear in the joint. However, the mechanism with multiple flexible links can absorb more of the energy arising from the clearance joint, and this improves the wear phenomenon.. ...

Around 22 cups with wear are listed in Appendix 8.4 and Table 58, representing over a third of the sample. There are several cases of the conical cup Drag. 33 being worn, these examples coming from various sites (Table 58). There are more examples of wear to cups with concave floors, particularly the Drag. 27, but also examples on Drag. 35 and 42, with these examples being associated with 1st to mid 2nd century AD dates (Table 58). The examples come from a variety of sites and locations implying, potentially, widespread practices in vessel use. In the case of a Drag. 35 from Alchester, Brenda Dickinson notes that it is heavily worn inside, perhaps as a result of liquids being stirred (2001d, 278). Biddulph notes that there are many cases of both Drag. 27 and 33 with wear among the c. 5000 sherds of samian from Elms Farm, Heybridge (2001). Significantly, Biddulph noted a consistent difference in the pattern of wear upon 27s as opposed to 33s. With the 27, the wear was central within the base, ...

Jac. van der Zaag deed onderzoek naar de diagnose, de etiologie en de behandelingsmethoden van slaapbruxisme Bruxisme is een bewegingsstoornis van het kauwstelsel die onder andere wordt gekenmerkt door tandenknarsen en klemmen. Het treedt zowel op gedurende de dag (waakbruxisme) als tijdens de slaap (slaapbruxisme). Tandartsen worden regelmatig geconfronteerd met patiënten met problemen die mogelijk gerelateerd zijn aan bruxisme, zoals ernstige gebitsslijtage in de vorm van attritie (mechanische slijtage als gevolg van kauwen of parafunctionele activiteit), temporomandibulaire (kaakgewricht) pijn, kauwspierhypertrofie (waarbij de kauwspier groter wordt) en breuk van gebitsrestauraties of zelfs van tandheelkundige implantaten. Van der Zaag laat zien dat er een sterke associatie is tussen slaapbruxisme, periodieke beenbewegingen tijdens de slaap (PLMS) en EEG-arousals (kortdurende hersenactivaties). Mogelijk hebben zij een gemeenschappelijk onderliggend neurofysiologische mechanisme. Van der Zaag ...
