An investigation into the mechanical behavior of single-walled carbon nanotubes under uniaxial tension using molecular statics and molecular dynamics simulations

This study performs a series of Molecular Dynamics (MD) and Molec- ular Statics (MS) simulations to investigate the mechanical properties of single- walled carbon nanotubes (SWCNTs) under a uniaxial tensile strain. The simula- tions focus specifically on the effects of the nanotube helicity, the nanotube diame- ter and the percentage of vacancy defects on the bond length, bond angle and tensile strength of zigzag and armchair SWCNTs. In this study, a good agreement is ob- served between the MD and MS simulation results for the stress-strain response of the SWCNTs in both the elastic and the plastic deformation regimes. The MS simulations reveal that in the plastic deformation regime, the tensile strength of the armchair and zigzag SWCNTs increases with an increasing wrapping angle. In addition, it is shown that the tensile strength reduces significantly at larger val- ues of the nanotube diameter. Moreover, it is observed that the tensile strength of both SWCNTs reduces as the percentage of defects within the nanotube structure increases. Finally, it is found that the results obtained from the molecular statics method are relatively insensitive to instabilities in the atomic structure, particularly in the absence of thermal fluctuations, and are in good agreement with the predic- tions obtained from the molecular dynamics method.
Decoding kinematic variables from Electroencephalographic (EEG) signals during lower-limb mobility protocols

Over 15% of the population of the world has some kind of disability, and a prevalent type is associated with their lower-limbs. In order to provide this type of disabled people with a mean to restore the mobility they once had, it comes to interest the usage of brain-machine interfaces (BMI). Many BMI studies have been done using the approach of electroencephalography (EEG); however, they tend to use a “classical scheme” which consists of classifying only the movement intention of the user. When this intention is detected, the system is programmed to automatically perform realistic movements according to the user’s wishes. This is why direct decoding from the EEG signals into limb kinematics would be preferable, as it gives the possibility of characterizing the intended movement in detail. A limited number of studies have implemented these “decoding schemes”; nevertheless, they just decode a single type of movement. This work will show some of the different methods currently used for decoding, as well as their comparison and performance for different sets of types of movements.
Interplanetary shock characteristics and associated geosynchronous magnetic field variations estimated from sudden impulses observed on the ground

[1] Interplanetary (IP) shocks disturb the magnetosphere-ionosphere system resulting in geosynchronous magnetic field changes and sudden impulses observed by ground-based magnetometers. We extend the implications of a previous statistical study and show that sudden impulses (SIs) can be used to estimate some parameters at the L1 point and geosynchronous orbit, including the change of the square root of solar wind dynamic pressure across the shock and the associated geosynchronous magnetic field changes near the subsolar region. It should be pointed out that the relationship between magnetospheric field change and SIs amplitude and the solar wind dynamic pressure is not a single valued one, but a statistical relationship is useful in cases when interplanetary data are not available. Empirical formulae deduced from observations can be used to estimate certain IP shock characteristics and geosynchronous magnetic field changes from sudden impulse data observed on the ground, with the prediction efficiency as high as 90% and 86%, respectively. These estimates are useful for studying historic, pre-space era data or if the L1 and geosynchronous data are not available at some future time.

Global impact of contemporary smoke aerosols from landscape fires on climate and the Hadley circulation

The manuscript presents a model-based evidence that biomass burning (BB) aerosol emissions are among important factors that determine patterns of climate variables (such as precipitation, air temperature, and radiative fluxes) and are related to general atmospheric circulation, especially in the tropics. The study is timely in light of increasing knowledge about biomass burning, and the efforts to understand the effects of different ecosystem components on climate and the effects of changing climate on Earth components. Earth system models are necessary tools for investigating these effects.
Sleeping beauties in technology - delayed recognition of breakthrough inventions

This paper analyzes the phenomenon of delayed recognition of breakthrough knowledge, that is, the phenomenon that some inventions initially do not diffuse, but only later become accepted. The failure in the recognition of these radical developments depends both on the social position of their authors, but also on their technological characteristics. Following the literature on delayed recognition and sleeping beauties in scientific papers, it identifies sleeping beauties in technologies as highly cited patents that did not receive citations for a long period, and it compares them to the control group of other highly cited patents from the same period. On the one hand, breakthroughs in the most codified technological areas are more susceptible to earlier appreciation. On the other hand, a collaboration between many of authors, as well as their previous experience, also facilitates preventing delayed recognition.
Factors Influencing Effectiveness of Volunteer Teachers Training in Non-Profit Organizations: Taking Angel Education as an Example

As the basic unit of composing society, the position and role of education cannot be ignored. With the development of social welfare and growing awareness for basic education, the volunteer teaching is becoming a great mass fervor in China. Many specialized non-profit organizations establish, numerous teaching programs undergo, and countless volunteers throw themselves in rural areas. The devotion of both non-profit organizations and volunteers will have great and far-reaching significance in public welfare. However, as this career is in full swing, problems also shadows. Due to the late start of volunteer teaching service in our country, the research on training theory, practice and legal guarantee is relatively laggard. Although everyone is equipped with enthusiasm for making contribution, their actual performance and teaching achievements are by no means satisfactory. An indispensable reason behind in most non-profit organizations is that training on voluntary teachers is relatively weak at different level, which may be the pivotal intermediate that influences the service result directly. After the research and analysis on a non-profit organization, the writer has found the training in the non-profit organization insufficient in training needs, forms, instructors, contents, evaluations and leadership. Therefore, the obstructive factors influencing the effectiveness of the training should be modified, to improve the service ability of non-profit organizations.
The Impact of ERP System's Usability on Enterprise Resource Planning Project Implementation Success via the Mediating Role of User Satisfaction

Organizations in the current environment need to create and sustain their competitive advantages. ERP (Enterprise Resource Planning) solutions are considered a strong tool that helps organizations to succeed and arise. But ERP projects’ implementation has relatively low success rates in which it may affect and shake the whole organizational performance. This study searches the power of software usability to achieve ERP Project Implementation Success (ERP-PIS) considering the mediating role of user information satisfaction (UIS). A set of research's hypotheses have been constructed. This study adapts a positivism view, using the survey strategy. The questionnaires were filled by 106 managers who use ERP systems or affected by ERP systems in different organizations. The findings of the research ensure the fitness of the model, and that mediation role of user information satisfaction (UIS) in Jordan is highly visible. Also, the research shows up the strong power of usability to achieve ERP-PIS. Based on the findings, development of ERP applications would be improved by software organizations in terms of usability, and organizations need to acquire ERP applications would also improve their decisions in choosing an ERP solution.
Techniques to Estimate Abundance and Monitoring Rodent Pests in Urban Environments

Different techniques have been developed in order to study the ecology of animals. The application of each technique depends on the studied animal species, on the type of habitats where they live and the objectives of the study. Most of the ecological studies focus on a unique population, which is defined as a group of organisms of the same species that coexist at the same time and in the same area (Krebs, 1978); or on a community, which is defined as a group of populations that exist at the same time and in the same area (Begon et al., 1987). One of the most important characteristics of a population is its size or abundance. This is determined by the number of individuals born, the number of individuals that dead and the number of individuals going into or out of the area that the population occupies per unit of time (Begon, 1979; Krebs, 1978). On the other hand, some of the characteristics of the animal community are the species composition, its absolute abundances and relative abundances, the richness, dominance, diversity, equitability, trophic structure and the niche structure (Krebs, 1978). Except for the trophic and niche structure, the other characteristics mentioned above are inferred from the abundances of the individual species that make up the community.
Progress in genetic manipulation of the Brassicaceae

Abstract With the increasing advances in Brassicaceae genetics and genomics, considerable progress has been made in the transformation of Brassicaceae. Transformation te-chnologies are now being exploited routinely to determine the gene function and contribute to the development of novel enhanced crops. Agrobacterium -mediated transformation remains the most widely used approach for the introduction of transgenes into Brassicaceae. In Brassica , the transformation relies mainly on in vitro transformation methods. Nevertheless, despite the significant progress made towards enhancing the transformation efficiencies, some genotypes remain recalcitrant to transformation. Advances in our understanding of the genetics behind various transformations have enabled researchers to identify more readily transformable genotypes for use in routine high-throughput systems. These developments have opened up exciting new avenues to exploit model Brassica genotypes as resources for understanding the gene function in complex genomes. Although many other Brassicaceae have served as model species for improving plant trans-formation systems, this paper summarizes on the recent technologies employed in the transformation of both
Genetic di v ersity among south Indian tea germplasm ( Camellia sinensis , C . assamica and C . assamica spp . lasiocalyx ) using AFLP markers

Amplified Fragment Length DNA Polymorphism (AFLP) analysis of 49 tea cultivars from south India produced a total number of 1555 unambiguous polymorphic amplified DNA fragments. The dendrogram derived by unweighted pair group method with arithmetic mean algorithm (UPGMA) analysis and the PCO plot drawn using principal component analysis revealed that all these tea cultivars could be clearly distinguished into three distinct groups viz., Assam, China and Cambod as well as an intermediate. Among the populations characterized, the Chinary type showed a maximum diversity index of 0.612 and the minimum of 0.285 was observed within the Assam type. Genetic distance was maximum (0.946), between Assam and Cambod and minimum (0.852) between Assam and China. More than 90% similarity as observed between the cultivars UPASI-22 and UPASI-23. Affinity of each cultivar towards the populations was determined using the similarity index. Analysis and comparison of AFLP fragments revealed distinct segregation of all the cultivars into their respective groups, except UPASI-18 and UPASI-24. Studies on diversity assessment of south Indian tea cultivars using AFLP fingerprinting revealed that the present day commonly grown south Indian tea germplasm has narrow genetic diversity (B/37.76) among the cultivars necessitating a sustained effort to preserve tea germplasm resources and the development of superior varietal material through wide genetic crosses. # 2003 Elsevier Science Ireland Ltd.

Assessing uncertainties in global cropland futures using a conditional probabilistic modelling framework

Abstract. We present a modelling framework to simulate probabilistic futures of global cropland areas that are conditional on the SSP (shared socio-economic pathway) scenarios. Simulations are based on the Parsimonious Land Use Model (PLUM) linked with the global dynamic vegetation model LPJ-GUESS (Lund–Potsdam–Jena General Ecosystem Simulator) using socio-economic data from the SSPs and climate data from the RCPs (representative concentration pathways). The simulated range of global cropland is 893–2380 Mha in 2100 (± 1 standard deviation), with the main uncertainties arising from differences in the socio-economic conditions prescribed by the SSP scenarios and the assumptions that underpin the translation of qualitative SSP storylines into quantitative model input parameters. Uncertainties in the assumptions for population growth, technological change and cropland degradation were found to be the most important for global cropland, while uncertainty in food consumption had less influence on the results. The uncertainties arising from climate variability and the differences between climate change scenarios do not strongly affect the range of global cropland futures. Some overlap occurred across all of the conditional probabilistic futures, except for those based on SSP3. We conclude that completely different socio-economic and climate change futures, although sharing low to medium population development, can result in very similar cropland areas on the aggregated global scale.
THE EFFECT OF PHYSICAL ACTIVITY ON RESILIENCY AND PRODUCTIVITY AND REDUCING STAFF ABSENCE BASED ON PUBLIC HEALTH OF UNIVERSITY ’ S FEMALE STAFF 1

The purpose of this research was to study the effect of 12-week physical activity on resiliency, productivity and reducing staff absence based on public health of the female staff of Islamic Azad University. In this paper, we used the pretest-posttest quasi-experimental study designs The method of this research was semi-experimental and carried out having pre-test and post-test with pre-test – post-test design with two control and experimental groups. The population of the research was consisted of 94 individuals among whom, the female staff of the university out of 94 academic staff, 48 persons were randomly selected and assigned to either of the control or experimental groups each containing 24 subjects. The tools for gathering data were the resiliency inventory of Connor and Davidson (2003) with Cronbach's alpha of r=0.90 and validity of r=0.84. The other questionnaire used for the productivity of workplace was and productivity inventory of Hang (2008), its reliability using reliability was r=0.71 and its validity was r=0.60 were used in order to measure the study variables. To test hypotheses independent t test and Mann Whitney test were used at α=0.05 to analyze the data. The results showed indicated that 12-week physical activity had significant effect on resiliency and productivity of the staff subjects. But the 12-week physical activity has not had a significant while the positive effect on reducing staff absence. It is recommended that managers stimulate regular physical exercise to all staff in organizations and to establish practical plans to provide physical activities, especially female staff whom suffering from special restrictions, can take advantages of this plan (productivity and resiliency).
Ameliorative Potential of Thiazolidinediones and Statins on Experimentally Induced Non-Alcoholic Steatohepatitis

Non-alcoholic steatohepatitis (NASH) is a chronic liver disease that may progress to advanced fibrosis and cirrhosis. Yet, its pathogenesis is not fully understood. The aim of this work was to study the possible protective effect of atorvastatin and pioglitazone on non-alcoholic steatohepatitis induced by high fat diet (HFD) in rats. Sixty male albino rats were divided into two main groups, the normal control group (ten rats) and HFD group (fifty rats) which was further subdivided into five subgroups (ten rats each) one of them received HFD+normal saline (NASH group), the 2nd received HFD + vehicle (gum tragacanth), the 3rd received HFD+atorvastatin, the 4th received HFD+ pioglitazone and the last group received HFD+atorvastatin and pioglitazone. At the end of the study, animals were killed and blood samples were collected for estimations of serum ALT, AST, ALP, TNF-α, triglycerides, total cholesterol, glucose, insulin and HOMA-IR. Also, samples of liver were taken and studied for hepatic triglycerides, malondialdehyde, free fatty acids and histopathological analysis. Atorvastatin lowered efficiently serum ALT, AST, ALP, TNF-α, total cholesterol, triglycerides, hepatic triglycerides, malondialdehyde and free fatty acids, together with marked improvement in histopathology of liver steatohepatitis, but, produced insignificant effects on fasting blood glucose, serum insulin and HOMA-IR. On the other hand, administration of pioglitazone, whether alone or in combination with atorvastatin induced significant improvement of all the above mentioned parameters. In conclusion, if the prominent feature in NASH is insulin resistance, we recommend the use of pioglitazone, while atorvastatin will be needed if the prominent features is hyperlipidemia and both drugs simultaneously if there are both hyperlipidemia and insulin resistance.
Long-term phosphate fertilization, mycorrhizal inoculation and historical land use influence on soybean growth and P uptake

Phosphorus is a key-nutrient in the fertility management of highly weathered tropical soils. So, this work was carried out with the objective of evaluating the influence of the interaction between P doses, mycorrhizal inoculation and historical land use on soybean growth and P uptake in five Latosols (Oxisols) with contrasting chemical, physical and mineralogical properties under a continuous long-term phosphate fertilization (more than 15 years). The plants were cultivated in 4.5L-plastic pots containing 4 kg of soil in a completely randomized design, four replications and 2x2x2 factorial scheme with two P doses; and with or without mycorrhizal inoculation; and soils cultivated for long periods and non-cultivated (under native vegetation). There were two cultivations of ten weeks each. Shoot dry mass, P content and accumulation in the shoot dry mass were evaluated after each cultivation period. The cultivation history reduced the response to P application and inoculation. The soybean response to inoculation was greater in cultivated soils and when the lower P dose was applied. The soybean response magnitude to these variables was different among the studied Latosols. The mineralogical and chemical attributes of the Latosols were determinants.
Antimicrobial Peptides Induce Growth of Phosphatidylglycerol Domains in a Model Bacterial Membrane

We performed microsecond long coarse-grained molecular dynamics simulations to elucidate the lateral structure and domain dynamics of a phospha- tidylethanolamine (PE)/phosphatidylglycerol (PG) mixed bilayer (7/3), mimicking the inner membrane of gram-negative bacteria. Specifically, we address the effect of surface bound antimicrobial peptides (AMPs) on the lateral organization of the membrane.Wefindthat, intheabsenceofthe peptides,theminor PGfractiononly forms small clusters, but that these clusters grow in size upon binding of the cationic AMPs. The presence of AMPs systematically affects the dynamics and induces long-range order in the structure of PG domains, stabilizing the separation between the two lipid fractions. Our results help in understanding the initial stages of destabilization of cytoplasmic bacterial membranes below the critical peptide concentration necessary for disruption, and provide a possible explanation for the multimodal character of AMP activity.

Hereditary Endometrial Carcinoma

Cancer of the uterine endometrium is the most common gynecologic malignancy diagnosed in women of the United States. It is estimated that in 2011, there will be 46,470 new endometrial cancers and 8,120 deaths due to this malignancy (American Cancer Society, 2011). The lifetime risk of developing endometrial cancer is approximately 3% in the general population. In Western countries, lifestyle changes and environmental factors play an important role in the carcinogenesis of endometrial cancer; however, there exist a proportion of cases in which an inherited predisposition increases this risk. In this chapter, hereditary nonpolyposis colorectal cancer syndrome or more commonly, Lynch Syndrome, will be reviewed and its association with endometrial cancer detailed.
When will MLS programs wake up and smell the LILACs

For over thirty years, numerous studies have discussed the contradiction between the growing importance of information literacy instruction to the Library’s core mission and lack of pedagogical training for new librarians. This article reviews the more recent contributions on the topic, presents a survey of New York State MLS curricula and describes initiatives of pedagogy training offered in that region outside of MLS programs. The authors focus on the Library Instruction Leadership Academy (LILAC), an innovative, semester-long training program created in Western New York State to offer instruction in the pedagogical foundation and practical experience essential for teaching information literacy skills effectively. They provide details of the program’s content, organization, funding, assessment methods, and learning outcomes. While regional initiatives like LILAC prove to be very valuable to their participants, the authors aim to apply pressure on MLS programs to establish curricular requirements better suited to the demands of today's librarianship.
