Cell death during corneal storage at 4 degrees C. (1/369)

PURPOSE: To evaluate cell death in human donor corneas stored at 4 degrees C, to determine whether terminal deoxynucleotidyl transferase-mediated dUTP-fluorescein nick-end labeling (TUNEL) discriminates between apoptosis and necrosis in corneas stored at 4 degrees C. METHODS: Ten human corneas were stored in Optisol (Chiron Ophthalmics, Irvine, CA) at 4 degrees C for periods ranging from 0 to 21 days and then fixed for histologic examination. Central corneal sections from each cornea were examined by transmission electron microscopy (TEM) and by the TUNEL assay. Electron micrographs of at least 15 keratocytes each from the anterior, middle, and posterior stroma were examined by three masked observers who graded each cell as normal, apoptotic, or necrotic. Central sections from the same corneas were processed by the TUNEL assay and evaluated with a laser scanning confocal microscope to determine the percentage of apoptotic cells. RESULTS: By TEM, apoptosis occurred in 23% of the keratocytes and necrosis in 12%. By TUNEL assay, apoptosis occurred in 11% of the keratocytes, with the results in individual corneas being similar to the findings by TEM for apoptosis, rather than for necrosis. By TUNEL assay, apoptosis occurred in 13% of the epithelial cells and in 8% of the endothelial cells. The percentage of apoptotic cells and storage time correlated significantly for the epithelium, but not for the keratocytes or endothelium in this small sample. CONCLUSIONS: Both apoptosis and necrosis occur in cells during corneal storage at 4 degrees C, with apoptosis appearing to predominate. The TUNEL assay identifies cells undergoing apoptosis, but not necrosis, in corneal tissue. Inhibition of apoptosis in corneas stored at 4 degrees C may prolong acceptable storage times.  (+info)

Effectiveness of microabrasion technique for improvement of dental aesthetics. (2/369)

OBJECTIVES: To investigate which types of enamel opacity are effectively treated by the microabrasion technique and whether this technique could be used as a diagnostic aid to determine the aetiology of these defects. MATERIALS AND METHOD: Thirty two patients who had enamel opacities affecting both upper central incisors were selected and the disfigurements were classified into four types: single line, multi-line, patched and diffused. The patient's previous medical history, possible history of fluoride ingestion, presence of taurodontism and family history of similar enamel defects were recorded. Both incisors were treated with Prema abrasive paste mixed with 18% hydrochloric acid. The aesthetic improvements were assessed by the patients and their parents and their satisfaction level after the treatment was recorded. RESULTS: Approximately two-thirds (65.6%) of the patients were satisfied with their appearance after microabrasion. Apart from four patients, the improved appearance was stable and acceptable to the remaining patients at the six month recall. Statistical analysis showed that acceptable improvement was found in patients with single line/patched types of defects but not in multi-line/diffused types (P = 0.03). However, the aesthetic improvement was not related to the patient's fluoride history, presence of taurodontism or the family history of enamel defects. CONCLUSION: Microabrasion using Prema abrasives with 1 8% HCI is effective in improving the appearance of enamel with single-line or patched opacities, indicating that these defects are a surface phenomenon. For the multi-line and diffused types, the defects appear to extend deeper into the enamel. The technique failed to assist in determining the aetiology of these defects.  (+info)

GFS, a preparation of Tasmanian Undaria pinnatifida is associated with healing and inhibition of reactivation of Herpes. (3/369)

BACKGROUND: We sought to assess whether GFS, a proprietary preparation of Tasmanian Undaria pinnatifida, has effects on healing or re-emergence of Herpetic infections, and additionally, to assess effects of GFS in vitro. Undaria is the most commonly eaten seaweed in Japan, and contains sulphated polyanions and other components with potential anti-viral activity. Herpes simplex virus type 1 (HSV-1) infections have lower reactivation rates and Herpes type 2 (HSV-2) infections have lower incidence in Japan than in the west. METHODS: Patients with active (15 subjects) or latent (6 subjects) Herpetic infections (HSV-1, 2, EBV, Zoster) were monitored for response to ingestion of GFS. GFS extract was tested in vitro for human T cell mitogenicity and anti-Herpes activity. RESULTS: Ingestion of GFS was associated with increased healing rates in patients with active infections. In addition, patients with latent infection remained asymptomatic whilst ingesting GFS. GFS extract inhibited Herpes viruses in vitro and was mitogenic to human T cells in vitro. CONCLUSIONS: Ingestion of GFS has inhibitory effects on reactivation and is associated with increased rate of healing after Herpetic outbreaks. GFS extract potently inhibited Herpes virus in vitro, and had mitogenic effects on human T cells.  (+info)

The use of antimicrobial peptides in ophthalmology: an experimental study in corneal preservation and the management of bacterial keratitis. (4/369)

PURPOSE: Bacterial keratitis is an ocular infection with the potential to cause significant visual impairment. Increasing patterns of antibiotic resistance have necessitated the development of new antimicrobial agents for use in bacterial keratitis and other serious ocular infections. With a view to exploring the use of novel antimicrobial peptides in the management of ocular infection, we performed a series of experiments using synthetic antimicrobial peptides designed for the eradication of common and serious ophthalmic pathogens. METHODS: Experiments were performed with three clinical ocular isolates--Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis--in three experimental settings: (1) in vitro in a controlled system of 10 mM sodium phosphate buffer, (2) in vitro in modified chondroitin sulfate-based corneal preservation media (Optisol), and (3) in an in vivo animal model (rabbit) simulating bacterial keratitis. In all cases, outcomes were measured by quantitative microbiological techniques. RESULTS: The candidate peptides (CCI A, B, and C and COL-1) produced a total reduction of the test pathogens in phosphate buffered saline. In modified Optisol, the peptides were effective against S epidermidis at all temperatures, demonstrated augmented activity at 23 degrees C against the gram-positive organisms, but were ineffective against P aeruginosa. The addition of EDTA to the medium augmented the killing of P aeruginosa but made no difference in the reduction of gram-positive organisms. In an in vivo rabbit model of Pseudomonas keratitis, COL-1 demonstrated neither clinical nor microbicidal efficacy and appeared to have a very narrow dosage range, outside of which it appeared to be toxic to the ocular surface. CONCLUSION: Our data indicate that the antimicrobial peptides we tested were effective in vitro but not in vivo. In an age of increasing antibiotic resistance, antimicrobial peptides, developed over millions of years as innate defense mechanisms by plants and animals, may have significant potential for development as topical agents for the management of severe bacterial keratitis. However, modifications of the peptides, the drug delivery systems, or both, will be necessary for effective clinical application.  (+info)

Crude extracts of bacterially expressed dsRNA can be used to protect plants against virus infections. (5/369)

BACKGROUND: Double-stranded RNA (dsRNA) is a potent initiator of gene silencing in a diverse group of organisms that includes plants, Caenorhabditis elegans, Drosophila and mammals. We have previously shown and patented that mechanical inoculation of in vitro-transcribed dsRNA derived from viral sequences specifically prevents virus infection in plants. The approach required the in vitro synthesis of large amounts of RNA involving high cost and considerable labour. RESULTS: We have developed an in vivo expression system to produce large amounts of virus-derived dsRNAs in bacteria, with a view to providing a practical control of virus diseases in plants. Partially purified bacterial dsRNAs promoted specific interference with the infection in plants by two viruses belonging to the tobamovirus and potyvirus groups. Furthermore, we have demonstrated that easy to obtain, crude extracts of bacterially expressed dsRNAs are equally effective protecting plants against virus infections when sprayed onto plant surfaces by a simple procedure. Virus infectivity was significantly abolished when plants were sprayed with French Press lysates several days before virus inoculation. CONCLUSION: Our approach provides an alternative to genetic transformation of plant species with dsRNA-expressing constructs capable to interfere with plant viruses. The main advantage of this mode of dsRNA production is its simplicity and its extremely low cost compared with the requirements for regenerating transgenic plants. This approach provides a reliable and potential tool, not only for plant protection against virus diseases, but also for the study of gene silencing mechanisms in plant virus infections.  (+info)

Protein stability in mixed solvents: a balance of contact interaction and excluded volume. (6/369)

Changes in excluded volume and contact interaction with the surface of a protein have been suggested as mechanisms for the changes in stability induced by cosolvents. The aim of the present paper is to present an analysis that combines both effects in a quantitative manner. The result is that both processes are present in both stabilizing and destabilizing interactions and neither can be ignored. Excluded volume was estimated using accessible surface area calculations of the kind introduced by Lee and Richards. The change in excluded volume on unfolding, deltaX, is quite large. For example, deltaX for ribonuclease is 6.7 L in urea and approximately 16 L in sucrose. The latter number is greater than the molar volume of the protein. Direct interaction with the protein is represented as the solvent exchange mechanism, which differs from ordinary association theory because of the weakness of the interaction and the high concentrations of cosolvents. The balance between the two effects and their contribution to overall stability are most simply presented as bar diagrams as in Fig. 3. Our finding for five proteins is that excluded volume contributes to the stabilization of the native structure and that contact interaction contributes to destabilization. This is true for five proteins and four cosolvents including both denaturants and osmolytes. Whether a substance stabilizes a protein or destabilizes it depends on the relative size of these two contributions. The constant for the cosolvent contact with the protein is remarkably uniform for four of the proteins, indicating a similarity of groups exposed during unfolding. One protein, staphylococcus nuclease, is anomalous in almost all respects. In general, the strength of the interaction with guanidinium is about twice that of urea, which is about twice that of trimethylamine-N-oxide and sucrose. Arguments are presented for the use of volume fractions in equilibrium equations and the ignoring of activity coefficients of the cosolvent. It is shown in the Appendix that both the excluded volume and the direct interaction can be extracted in a unified way from the McMillan-Mayer formula for the second virial coefficient.  (+info)

Solvation of nucleosides in aqueous mixtures of organic solvents: relevance to DNA open basepairs. (7/369)

Toward the goal of understanding how open basepairs in DNA interact with their heterogeneous environment, we have studied the steady-state intrinsic fluorescence properties of the purine and pyrimidine deoxynucleosides in organic solvents in the presence of small amounts of water. The organic solvents used in the present study were: n-butanol, acetonitrile, methanol, n-propanol, isopropanol, and isobutanol. For n-butanol and acetonitrile, which have a high degree of amphiphilicity and weak hydrogen bonding ability, respectively, the fluorescence spectral properties of the purines are found to depend on the sequence of steps in which the aqueous mixtures were formed. By contrast, no such dependence was observed in the mixtures with any of the other solvents used in the present study. Moreover, no such dependence was observed for the pyrimidines. These findings suggest that the final solvation network around the purines is dependent on the nature of the environment to which they were initially exposed. This would tend to present an impediment to the closing of AT or GC basepairs in DNA that become open as a result of structural fluctuations, DNA bending, or protein-DNA interactions.  (+info)

Egg hatching, larval movement and larval survival of the malaria vector Anopheles gambiae in desiccating habitats. (8/369)

BACKGROUND: Although the effects of rainfall on the population dynamics of the malaria vector Anopheles gambiae have been studied in great detail, the effects of dry periods on its survival remain less clear. METHODS: The effects of drying conditions were simulated by creating desiccated habitats, which consisted of trays filled with damp soil. Experiments were performed in these trays to (i) test the ability of An. gambiae sensu stricto eggs to hatch on damp soil and for larvae to reach an artificial breeding site at different distances of the site of hatching and (ii) to record survival of the four larval stages of An. gambiae s.s. when placed on damp soil. RESULTS: Eggs of An. gambiae s.s. hatched on damp soil and emerging larvae were capable of covering a distance of up to 10 cm to reach surface water enabling further development. However, proportions of larvae reaching the site decreased rapidly with increasing distance. First, second and third-instar larvae survived on damp soil for an estimated period of 64, 65 and 69 hrs, respectively. Fourth-instar larvae survived significantly longer and we estimated that the maximum survival time was 113 hrs. CONCLUSION: Short-term survival of aquatic stages of An. gambiae on wet soil may be important and adaptive when considering the transient nature of breeding sites of this species in sub-Saharan Africa. In addition, the results suggest that, for larval vector control methods to be effective, habitats should remain drained for at least 5 days to kill all larvae (e.g. in rice fields) and habitats that recently dried up should be treated as well, if larvicidal agents are applied.  (+info)

Downloadable! In finite mixture model clustering, each component of the fitted mixture is usually associated with a cluster. In other words, each component of the mixture is interpreted as the probability distribution of the variables of interest conditionally on the membership to a given cluster. The Gaussian mixture model (GMM) is very popular in this context for its simplicity and flexibility. It may happen, however, that the components of the fitted model are not well separated. In such a circumstance, the number of clusters is often overestimated and a better clustering could be obtained by joining some subsets of the partition based on the fitted GMM. Some methods for the aggregation of mixture components have been recently proposed in the literature. In this work, we propose a hierarchical aggregation algorithm based on a generalisation of the definition of silhouette-width taking into account the Mahalanobis distances induced by the precison matrices of the components of the fitted GMM. The

At each point of time \(t\), a GMVAR process generates an observation from one of its mixture components (also called regimes) according to the probabilities pointed by the mixing weights..

Let \(M\) be the number of mixture components, and \(\boldsymbol{s}_t=(s_{t,1},...,s_{t,M})\) a sequence of (non-observable) random vectors such that at each \(t\) exactly one of its components takes the value one and others take the value zero.

Sham will present the paper Competitive Algorithms for VWAP and Limit Order Trading, S. Kakade, M. Kearns, Y. Mansour and L. Ortiz. Wed Oct 6: Guest Speaker Yee Whye Teh, UC Berkeley Hierarchical Dirichlet processes: A Bayesian approach to sharing clusters among related groups Abstract: We consider problems involving groups of data, where each observation within a group is drawn from a mixture model, and where it is desirable to share mixture components both within and between groups. We assume that the number of mixture components is unknown a priori and is to be inferred from data. Such problems occur often in practice, e.g. in the problem of topic discovery in document corpora, each document is treated as a group of data items (bag of words), and each topic corresponds to a mixture component. In this setting, sharing components between groups simply means that topics can occur across a number of documents, allowing dependencies across documents (groups) to be modeled effectively as well as ...
Potash (especially potassium carbonate) has been used in bleaching textiles, making glass, and making soap, since about AD 500. Potash was principally obtained by leaching the ashes of land and sea plants. Beginning in the 14th century potash was mined in Ethiopia. One of the worlds largest deposits, 140 to 150 million tons, is located in the Tigrays Dallol area.[16] Potash was one of the most important industrial chemicals. It was refined from the ashes of broadleaved trees and produced primarily in the forested areas of Europe, Russia, and North America. The first U.S. patent of any kind was issued in 1790 to Samuel Hopkins for an improvement in the making of Pot ash and Pearl ash by a new Apparatus and Process.[17] Pearl ash was a purer quality made by calcination of potash in a reverberatory furnace or kiln. Potash pits were once used in England to produce potash that was used in making soap for the preparation of wool for yarn production. As early as 1767, potash from wood ashes was ...

Note. In this case, where the experimental region forms a simplex, it matters little which direction you take. Check this out by going to the Trace Graph tool and pressing Cox. In the Cox direction, as the amount of any component increases, the amounts of all other components decrease, but their ratio to one another remains constant. Chemists may like this because it preserves the reaction stoichiometry. However, when plotted in this direction, traces for highly constrained mixture components (such as a catalyst for a chemical reaction) become truncated. Thus, mixture-design experts argue that although it no longer holds actual ratios constant, Piepels direction provides a more helpful plot by providing the broadest coverage of the experimental space. For this reason Piepel is the preferred plot in Design-Expert. For more detail, search in Help for trace plot.. P.S. Trace plots depend greatly on where you place the starting point (by default the centroid). See for yourself by moving slide ...

Downloadable! This paper exploits the fact that implied volatilities calculated from identical call and put options have often been empirically found to differ, although they should be equal in theory. We propose a new bivariate mixture multiplicative error model and show that it is a good fit to Nikkei 225 index call and put option implied volatility (IV). A good model fit requires two mixture components in the model, allowing for different mean equations and error distributions for calmer and more volatile days. Forecast evaluation indicates that in addition to jointly modeling the time series of call and put IV, cross effects should be added to the model: putside implied volatility helps forecast callside IV, and vice versa. Impulse response functions show that the IV derived from put options recovers faster from shocks, and the effect of shocks lasts for up to six weeks.
Abstract Polymer spots with entrapped glucose oxidase were fabricated on glass surfaces and the localized enzymatic response was subsequently visualized using scanning electrochemical microscopy (SECM) in the generator,collector mode. SECM images were obtained under simultaneous variation of the concentration of glucose (0,6,mM) and ascorbic acid (0,200,,M), or, in a second set of experiments, of glucose (0,2,mM) and 2-deoxy- D(+)-glucose (0,4,mM). Aiming at the quantification of the mixture components discretization of the response surfaces of the overall enzyme/polymer spot into numerous spatially defined microsensor substructures was performed. Sensitivity of sensor substructures to measured analytes was calculated and patterns of variability in the data were analyzed before and after elimination of interferences using principal component analysis. Using artificial neural networks which were fed with the data provided by the sensor substructures showing highest sensitivity for glucose, ...

The plenary session was opened by the coordinator of ATHON - Dr. Helen Håkansson of the Karolinska Institutet in Sweden - who gave a brief introduction on the ATHON project and the relevance of mixture toxicity for NDL-PCB risk assessment. Next, Dr. Thomas Backhaus (University of Gothenburg, Sweden), gave an introduction to the general principles of concentration addition (CA) and independent action (IA) within mixture toxicity, which was illustrated with an abundance of practical examples. The general conclusion from his presentation was that for hazard and risk assessment, the selection between a CA or IA model seems to be of minor importance. Keeping in mind the adage seek simplicity but distrust it, Dr. Backhaus advocated that CA might be a simple default assumption to start with and to work further from. The third plenary speaker was Dr. Niklas Johansson (Swedish EPA and Karolinska Institutet) who demonstrated the use of a Central Composite, Face centered (CCF) statistical test ...

A longer chromatography gradient can give more separation of peptides. More important, it gives the mass spectrometer time to measure more peptides. In a gradient of 1% acetonitrile/minute, in the 6 seconds to change from 30% to 30.1% acetonitrile, the instrument can analyze 18 peptides. Using a gradient of 0.25% acetonitrile/min, 72 peptides can be analyzed, allowing more proteins to be found.. In some cases, the peptide mixture is fractionated by ion exchange or other method before the reverse phase separation mentioned above. This is 2D-LC, referred to as MUDPIT by some. This increases the number of analyses.. Not every peptide is analyzed. This is always the case. Some peptides are always on a black list not be be analyzed-peptides from trypsin, peptides from keratin-an almost universal contaminant.

Receptor tyrosine kinases (RTKs) play a critical role in diverse cellular processes and their activity is regulated by lipids in the surrounding membrane, including PIP2 (phosphatidylinositol-4,5-bisphosphate) in the inner leaflet, and GM3 (monosialodihexosylganglioside) in the outer leaflet. However, the precise details of the interactions at the molecular level remain to be fully characterised. Using a multiscale molecular dynamics simulation approach, we comprehensively characterise anionic lipid interactions with all 58 known human RTKs. Our results demonstrate that the juxtamembrane (JM) regions of RTKs are critical for inducing clustering of anionic lipids, including PIP2, both in simple asymmetric bilayers, and in more complex mixed membranes. Clustering is predominantly driven by interactions between a conserved cluster of basic residues within the first five positions of the JM region, and negatively charged lipid headgroups. This highlights a conserved interaction pattern shared across the
If soil Indices* are below the target level the second section of the Calculator provides a guide to the quantity of nutrient which is likely to be required to correct the deficiency. This will vary according to the level of deficiency and the soil type. The quantity will usually be more than can reasonably be applied in one season, and the Calculator asks by how much and how quickly you want to correct the deficiency, i.e. over how many years. The desired improvement can be input by Index or more precisely by mg/litre as determined by soil analysis*. Once all relevant information has been input (for one or both nutrients) clicking on the Calculate button will provide a guide to the total quantity of nutrient(s) which will be required. The annual dressing is also shown, according to the timescale selected. The bottom line shows this annual deficiency-correcting application, together with the maintenance dressing. The cost of the nutrient(s) required to correct the deficiency should not be ...

The capability to analyze complex mixtures of airborne volatile organic compounds (VOCs) at low concentrations; in situ; has implications for environmental monitoring; worker exposure assessment; biomedical diagnostics; and population security. Since standalone microsensor arrays lack this capability; upstream separation of mixture components; often preceded by preconcentration; is required. Although significant advances have been made via MEMS technologies in the development of microscale gas chromatographic (μGC) systems; many challenges remain. This presentation will review selected aspects of the state-of-the-art in μGC for VOC mixture analysis. Here; we emphasize our progress toward a wearable μGC prototype.

Many model-based clustering methods are based on a finite Gaussian mixture model. The Gaussian mixture model implies that the data scatter within each group is elliptically shaped. Hence non-elliptical groups are often modeled by more than one component, resulting in model over-fitting. An alternative is to use a mean-variance mixture of multivariate normal distributions with an inverse Gaussian mixing distribution (MNIG) in place of the Gaussian distribution, to yield a more flexible family of distributions. Under this model the component distributions may be skewed and have fatter tails than the Gaussian distribution. The MNIG based approach is extended to include a broad range of eigendecomposed covariance structures. Furthermore, MNIG models where the other distributional parameters are constrained is considered. The Bayesian Information Criterion is used to identify the optimal model and number of mixture components. The method is demonstrated on three sample data sets and a novel variation ...
Background: There has been different interpretation of kosmotropes and chaotropes without concern for the physicochemical characteristics of the macromolecule and for the link between Hofmeister phenomena with solution structure. The objectives of this research are: 1) To investigate different ways of determining activity coefficient and activity of ionic osmolyte 2), to present a common theoretical basis for the interaction between reaction mixture components and Hofmeister phenomena and 3) determine the preferential interaction parameters and the Kirkwood-Buff integrals.. Methods: A major theoretical research and partly experimental.. Results and Discussion: Some equations in literature gave different values of activity coefficient and activity of solution components. The preferential interaction by binding is positive with ethanol only and at its higher concentration in the presence of ideal solution of different concentration of calcium chloride. There was positive m-value with ethanol. It ...
A solution mining method is applied at the Bethune potash mine. The process involves dissolving underground water-soluble minerals with water, commonly referred to as brine. The water is then extracted from the ground and the contained minerals are recovered from it.. This project involves two mining phases, primary and secondary. The primary method uses fresh water, which is injected into the ground through two boreholes. The fresh water is mixed with the potash-bearing salt rock. Two single circular caverns were formed, approximately 80m apart and 1,500m below the surface.. In the secondary phase, the mine uses a sodium chloride-saturated brine to selectively dissolve the potassium chloride from the walls and roof of the caverns. The sodium chloride solution is injected below the Esterhazy seam and the deposit will be solution-mined up to 3m thick horizontal layers.. The potash brine solution from the underground is transported to surface through two boreholes and processed further. The mine ...

The worlds chemical production has increased more than 50-fold since the 1950s and several studies have shown that hazardous chemical exposure contributes substantially to diseases and affects human and environmental health in a profound way.. Most of these studies have, however, only dealt with single substances. In reality we are exposed to complex mixtures of man-made chemicals every day, and how such chemical pressures affect us is poorly understood.. While the European Union have certain systems in place for limiting adverse effects from single hazardous substances the challenge remains to reduce the risks from the mixtures and the total exposure of hazardous chemicals in our lives. Currently, in EU legislation, there is no mechanism for a systematic assessment of mixture effects taking into account different routes of exposure and different product types.. Voices have been raised to address this problem on a legislative level before, but now the wheels are set in motion with the Swedish ...

muriates of potash ; they scintillate when thrown upon burning coals, and deflagrate with charcoal. When fused, they afford abundance of oxygen gas, and the compound of potassium and the new body, remains. After the mother liquor has ceased to yield crystals, if it is evaporated to dryness, it affords a large quantity of the compound of the substance with potassium; so that by dissolving the substance in solution of potash, the two new products are formed. When the substance in vapour is passed over dry red hot potash formed immediately from potassium, the oxygen of the potash is expelled, and the substance combines with potassium ; so that the triple combination of this compound with oxygen, does not exist at a red heat. It presents the same phænomena with solutions of soda and baryta. It is obvious, therefore, that the earlier discovery of this singular substance, would have led to the discovery of the fixed alcalies being oxidized metals, without the agency of Galvanic electricity. While it ...

The Spectre and Meltdown flaws in modern microprocessors represent a new class of attacks that have been difficult to mitigate. The mitigations that have been proposed have known performance impacts. The reported magnitude of these impacts varies depending on the industry sector and expected workload characteristics. In this paper, we measure the performance impact on several workloads relevant to HPC systems. We show that the impact can be significant on both synthetic and realistic workloads. We also show that the performance penalties are difficult to avoid even in dedicated systems where security is a lesser concern.
The uncanny coincidences among the Meltdown and Spectre discoveries raise questions about bug collisions-and the safety of the NSAs hidden vulnerability collection.

Nitrogen (N) and Potash (K) are what fruit and nut trees need the most of. Phosphorus (P) needs are smaller but just as necessary. Other important nutrients include calcium and magnesium in addition to manganese, zinc, boron, copper, iron, and others.. Where land has been abused, or is naturally deficient in some trace element, nutritional deficiencies in your trees may occur. These deficiencies often show in the form of fungal diseases, though they can also manifest insect damage, hail damage, etc.. If mulch is not giving your trees enough of the important nutrients, other natural, slow-release fertilizers can provide them. Rock phosphate and bone meal will supply additional phosphorus, if needed. Wood ashes are an excellent source of potash, and they also contain high amounts of calcium. Manure is good for both nitrogen and potash. Bloodmeal, cottonseed meal, and soybean meal are slow releasers of nitrogen. In situations where you need both calcium and magnesium, dolomitic limestone or oyster ...
