Examining Structural and Related Spectral Change in Mars-relevant Phyllosilicates After Experimental Impacts Between 10–40 GPa

Accurate clay mineral identification is key to understanding past aqueous activity on Mars, but martian phyllosilicates are old (>3.5 Ga) and have been heavily bombarded by meteoroid impacts. Meteoroid impacts can alter clay mineral structures and spectral signatures, making accurate remote sensing identifications challenging. This paper uses nuclear magnetic resonance (NMR) spectroscopy to examine the short-range structural deformation induced in clay mineral samples of known composition by artificial impacts and calcination. Structural changes are then related to changes in the visible-near infrared (VNIR) and mid-infrared (MIR) spectra of these clay mineral samples. The susceptibility of phyllosilicates to structural deformation after experimental impacts varies by structure. Experimental results showed that trioctahedral, Mg(II)-rich saponite was structurally resilient up to peak pressures of 39.8 GPa and its unchanged post-impact spectra reflected this. Experimental data on kaolinite showed that this Al(III)-rich, dioctahedral phyllosilicate was susceptible to structural alteration at peak pressures ⩾ 25.1 GPa. This result is similar to previously reported experimental results on the Fe(III)-rich dioctahedral smectite nontronite, suggesting that dioctahedral phyllosilicates may be more susceptible to shock-induced structural deformation than trioctahedral phyllosilicates. The octahedral vacancies present in dioctahedral phyllosilicates may drive this increased susceptibility to deformation relative to trioctahedral phyllosilicates with fully occupied octahedral sheets. Thermal alteration accompanies shock in meteoroid impacts, but shock differs from thermal alteration. NMR spectroscopy showed that structural deformation in thermally altered phyllosilicates differs from that found in shocked phyllosilicates. Similar to shock, dioctahedral phyllosilicates are also more susceptible to thermal alteration. This differential susceptibility to impact-alteration may help explain generic smectite identifications from heavily bombarded terrains on Mars.
Thinlayer Chromatography (TLC) and GC-MS Analysis of Somes Medicinal Plants Used in the Treatent of Haemorrhoids

Medicinal plant is one in which, one or more of its organs contains substances that can be used for therapeutic purposes or which are precursors for the synthesis of useful drugs The present study aimed at investigating the lipid composition of Axonopus compressus, Anogeiessus leiocarpus and Senna fistula commonly used in the management of haemorrhoids. The lipid analysis of the three plants was determined by TLC and GC-MS and the GC-MS analysis revealed the presence of some saturated fatty acids such as myristic, palmitic, linoleic, stearic, oleic and lauric acid in all the three extracts. In addition A. compressus contained linoleic and palmitoleic acids, S. fistula contained linolenic acid and A. leiocarpus contained linoleic, linolenic and behenic acids. However, palmitic (C 16 :0)) and stearic acid (C 18 :0) were observed to be the predominant fatty acids present in all the three plan extracts. The results showed that many active principles are present in the three plants which could contribute to their usefulness in the management of haemorrhoids.

The lutein free diet , a treatment option for autism

CONCLUSION: Ophthalmologic findings in autistic children appear to be mainly unilateral or bilateral astigmatism and binocular vision troubles. They can lead to amblyopia (chronic visual disorders) with the risk of functional loss of vision. Early diagnosis of visual problems in autistic children is also essential in order to be able to propose adequate psychological and educational care for the children and their family. ” [Ophthalmologic signs in children with autism; Denis D et al; 1997]

Profitable Association Mining rules based on Casual Survey Approach Using Apriori Algorithm

: In this technology specific era, everyone in industry look for smart methods to get profit in business. The biggest contribution is given by the introduction of Data Mining branch of Computer Science Engineering. The huge size of data is monitored, compressed and mined to get interesting facts. Different approaches are introduced day by day so as to formulate hidden associations between data. Following to which, new association rules are being generated. The base idea to find most occurring events was provided in Apriori Algorithm. In this paper we will analyse classical Apriori algorithm. We will introduce the concept of Casual Transaction database that includes direct survey from users i.e, how they trend to go for selections. We will propose an itea to integrate Casual transaction database with Real transaction database (what customer really does). We will analyse frequent itemset and association rules. We will then try to fit this approach with Apriori Algorithm. Accordingly we will keep this paper for our vision towards implementation of this approach and for our future work area.

Resumo. Este trabalho apresenta uma revisão sistemática com o objetivo de descrever o estado da arte sobre o tema Pensamento Computacional no Ensino Fundamental e Médio. Procurou-se identificar as principais abordagens neste tema, descrevendo seus objetivos, práticas pedagógicas, as ferramentas utilizadas e/ou propostas, bem como os conceitos e habilidades desenvolvidos. 1. Introdução As inovações tecnológicas possibilitam a realização de tarefas do dia a dia de forma inimaginável até alguns anos atrás. Estas mudanças também alteram as habilidades necessárias para a resolução de problemas, tanto na vida cotidiana como na educação do século XXI. Jeannette Wing [Wing 2006] descreveu o Pensamento Computacional (PC) como um processo de resolução de problemas, fundamentado na Ciência da Computação (CC), capaz de desenvolver muitas destas habilidades (tais como: abstração, automação, análise, entre outras). Em particular, a Computer Science Teachers Association (CSTA) e a International Society for Technology in Education (ISTE) junto com colaboradores propuseram a definição operacional do PC, delineando seu escopo e dimensões. Desde então, diversos trabalhos propuseram a introdução de conceitos de computação na educação, bem como o desenvolvimento de habilidades do PC em seus diferentes nı́veis. Pesquisas já relatam as diferentes estratégias adotadas para a introdução da computação na Educação Básica [Bordini et al. 2016a, Martins et al. 2016, Mota et al. 2014], bem como descrevem os desdobramentos do PC [Bordini et al. 2016b, Oliveira et al. 2016, Andrade et al. 2013], no Brasil.

Association between CDKN 2 BAS gene rs 4977574 polymorphism and susceptibility to coronary heart disease : evidence from 124 , 752 subjects

Objectives: To investigate the association between the CDKN2B-AS rs4977574 polymorphism and coronary heart disease. Methods: We performed a computerized comprehensive search on PubMed, Embase, OVID, Web of Science, CNKI, and Wan Fang databases up to December of 2016. Two of the authors individually extracted study data and assessed the study quality using NOS scale. Odds ratios (ORs) and 95% confidence intervals (CIs) were combined for evaluation using a random effect model or fixed effect model according to study heterogeneity. Results: There were totally twenty case-control studies of 51,522 patients and 73,230 healthy controls included. Significant associations were found between CDKN2B-AS rs4977574 polymorphism and CHD in overall population (OR = 1.26, 95% CI = 1.21-1.32, p<0.001, I2 = 79.2%). In subgroup analysis by ethnicity, we found significant association between the CDKN2B-AS rs4977574 polymorphism and CHD risk in both Asian (OR = 1.28, 95% CI = 1.191.38, I2 = 68.7%) and Caucasian (OR = 1.25, 95% CI = 1.18-1.32, I2 = 85.9%). Sensitivity analysis did not indicate any meaningful alternation in the odds ratios. The Begg’s funnel plot was used to assess the publication bias, showing no evidence of publication bias visually. Conclusion: The rs4977574 polymorphism in the CDKN2B-AS gene has susceptibility to CHD in Asians as well as Caucasians, indicating that the rs4977574 polymorphism of CDKN2B-AS gene may contribute to the pathogenesis of CHD.
Performance limits of graphene-ribbon field-effect transistors

The performance of field effect transistors based on an single graphene ribbon with a constriction and a single back gate are studied with the help of atomistic models. It is shown how this scheme, unlike that of traditional carbon-nanotube-based transistors, reduces the importance of the specifics of the chemical bonding to the metallic electrodes in favor of the carbon-based part of device. The ultimate performance limits are here studied for various constriction and metal-ribbon contact models. In particular, we show that, even for poorly contacting metals, properly tailored constrictions can give promising values for both the on conductance and the subthreshold swing.
A Parameterization of Sticking Efficiency for Collisions of Snow and Graupel with Ice Crystals: Theory and Comparison with Observations*

AbstractA new parameterization of sticking efficiency for aggregation of ice crystals onto snow and graupel is presented. This parameter plays a crucial role for the formation of ice precipitation and for electrification processes. The parameterization is intended to be used in atmospheric models simulating the aggregation of ice particles in glaciated clouds. It should improve the ability to forecast snow.Based on experimental results and general considerations of collision processes, dependencies of the sticking efficiency on temperature, surface area, and collision kinetic energy of impacting particles are derived. The parameters have been estimated from some laboratory observations by simulating the experiments and minimizing the squares of the errors of the prediction of observed quantities. The predictions from the new scheme are compared with other available laboratory and field observations. The comparisons show that the parameterization is able to reproduce the thermal behavior of sticking effici.
Impact of Replenishment Policies on the Value of Demand Information in a Serial Supply Chain

A supply chain includes material and information flows. Only when these two flows are managed simultaneously, the value of information can be maximized. This paper addresses this issue by investigating how the value of demand information is affected by inventory replenishment policies. Specifically, we consider two inventory replenishment practices, responsive and periodic replenishments, which govern the timing of inventory orders. The responsive replenishment is represented by a continuous-review (R, Q) policy, in which a location can order and ship inventory at any time if necessary. On the other hand, the periodic replenishment is represented by a periodic-review (S, T ) policy, in which a location can only order and ship periodically. There are fixed costs incurred for each inventory replenishment. Both replenishment policies are then implemented under two information scenarios: echelon and local information. The echelon information assumes that each location can update its inventory status based on the real-time customer demand. Comparing these four inventory policies enables us to understand when the supply chain benefits most if the echelon information is available, and how much a responsive replenishment practice helps to improve the system performance. In the literature, the (R, Q) and the echelon (S, T ) policies have been well studied. This paper analyzes the local (S, T ) policy. In particular, we construct an optimization algorithm and a simple heuristic for the policy parameters. Our study suggests that for the responsive replenishment, the value of demand information is marginally beneficial when the ratio of fixed order cost to holding cost is large at the most downstream stage. Interestingly, for the periodic replenishment, the value is significant in the above scenario.
Large Scale Sequencing and Analysis of AT Rich Eukaryote Genomes

Environmental pressures can direct genomes from a normal to a more or less pronounced imbalance in the base composition. These pressures seem to occur relatively often since genomes with a deviation from a normal base composition are widespread throughout lower eukaryotes. These genomes show altered codon usage and enrichment for the preferred bases in intron and intergenic regions. Techniques designed for large scale sequencing and assembly of genomes with normal base composition will fail with these unusual genomes. Additionally, the currently available analysis tools are mainly suitable for gene finding in genomes with normal base composition. In recent years some large scale genome analysis projects involving species with a skew directed to a very high AT content were initiated. These projects are encountered with sequencing, assembly, and gap closure problems due to the high AT content. These problems can only be overcome with additional techniques, which partly were developed and used in the ongoing projects. In this review some characteristic aspects of AT rich genomes, the progress of the Dictyostelium discoideum and the Plasmodium falciparum projects, as well as techniques specifically used for the sequencing of these genomes are highlighted. ANALYSIS OF GENOMES In recent years many bacteria, some archaea, and some eukaryotes were selected for genome sequencing and analysis projects. In a second step functional genomics then will provide insights into basic cellular processes (1). Economical value or expansion of knowledge was of decisive importance for the selection of distinct species. The analysis of genomes of economically interesting species like crop plants, soy bean, etc. may lead to an increase in food production (2). The knowledge of genomes of pathogens and parasites will probably help to develop novel drugs against defined targets in the pathogeneses. Other species chosen play a key role for the understanding of biological processes and phenomena. The comparison of whole genomes of species from different or consecutive evolutionary stages will elucidate the kind of key genes in evolutionary processes.
Email-based Password Recovery - Risking or Rescuing Users?

Secret passwords are very widely used for user authentication to websites, despite their known shortcomings. Most websites using passwords also implement password recovery to allow users to re-establish a shared secret if the existing value is forgotten; many such systems involve sending a password recovery email to the user, e.g. containing a secret link. The security of password recovery, and hence the entire user-website relationship, depends on the email being acted upon correctly; unfortunately, as we show, such emails are not always designed to maximise security and can introduce vulnerabilities into recovery. To understand better this serious practical security problem, we surveyed password recovery emails for 50 of the top English language websites. We investigated a range of security and usability issues for such emails, covering their design, structure and content (including the nature of the user instructions), the techniques used to recover the password, and variations in email content from one web service to another. Many well-known web services, including Facebook, Dropbox, and Microsoft, suffer from recovery email design, structure and content issues. This is, to our knowledge, the first study of its type reported in the literature. This study has enabled us to formulate a set of recommendations for the design of such emails.
Potential of electrostatic micro wind turbines

This paper presents the physical operating principles of several micro wind turbines based on different aerodynamic forces: drag-type Vertical Axis Wind Turbine (VAWT) and lift-type Horizontal Axis Wind Turbine (HAWT). All these devices share the similarity of exploiting the same mechanical-to-electrical conversion: the electrostatic conversion. This type of conversion is based on capacitance variations induced by the motion between a rotor and a stator and requires a source of polarization. We will focus our study on two technologies to polarize the capacitive structure: the use of electrets and the exploitation of triboelectricity. Some experiments conducted in a low-speed wind tunnel between 0 and 20m.s-1 have highlighted power flux densities from 0 to 150{\mu}W.cm-2 corresponding to power coefficients of 0 and 9% respectively. Among these results, we can especially retain an ultralow speed operation, which has never been reached until now, in terms of speed and efficiency (9% of efficiency at 1m.s-1). Finally, we will end up comparing different types of circuits to supply a temperature/acceleration sensor, in order to complete the energy harvesting chain.
Prevalence of Nasal Staphylococcus aureus Colonization in a Dermatology Practice and Implications for Care

bacterium that is a prevalent and detrimental pathogen in humans. Infections associated with this common bacterial microorganism are increasingly problematic in hospital and other healthcare settings. Staphylococcus aureus (S. aureus) and, more recently, methicillin-resistant Staphylococcus aureus (MRSA) can cause skin and soft tissue infections, urinary tract infections, pneumonia, invasive infections, surgical site infections (SSI), and are the leading causes of nosocomial infections. S. aureus nasal carriers have a twoto 10-fold increased risk of developing SSI or intravenous catheter infections. Increased prevalence of infections has significantly impacted the field of dermatology and therefore raised the importance of determining contributory factors in the matter. The anterior nares are a primary reservoir for S. aureus, and individuals have historically been designated as persistent carriers (approximately 20 percent of individuals), intermittent carriers (~30 percent), and non-carriers (~50 percent). The purpose of this study is to determine the prevalence of nasal carriage of S. aureus in a healthcare subpopulation, specifically among a dermatology practice. In order to determine how many patients were S. aureus carriers in a dermatology practice, a brief questionnaire and bacterial nasal swabs were obtained from 50 participants.
