Gross Anatomical and Histometric Studies on the Stomach Glandular Sacs of the Dromedary Camel (Camelus dromedarius)

2014 Camel glandular sac areas were previously considered as water stores. Recently, these sacs were found to be glandular areas which are probably involved in absorption, fermentation and secretion functions. This investigation aimed to study the gross anatomical and histometry of the glandular sacs of camel stomach. It was conducted on fifteen adult camels and ten foetuses. The camel stomach composed of four compartments; compartment 1, compartment 2, compartment 3, and compartment 4. Compartment 1 which was the largest extended from the diaphragm to the caudal border of the 12 thoracic rib in foetuses and presented glandular cranioventral and caudodorsal sacs and non-glandular areas. The cranioventral sac was oval in shape with more or less smooth external surface. The caudodorsal sac was irregular and relatively larger and more sacculated. Each sac contained glandular pits which were formed by four walls; the walls originated from two longitudinal and two transverse pillars which surrounded the pit floor. The pit walls and floor consisted of four tunics; mucosa, submucosa, muscularis and serosa. The pit wall mucosa was non-glandular and the floor mucosa was glandular with serous glands. No significant histometric differences were observed between the cranioventral and caudodorsal sacs in the glandular size (glandular length and diameter) and thickness of wall tunics (tunica mucosa, submucosa, muscularis and serosa).  2014 Sudan University of Science and Technology.

EFL LEARNERS' SENSITIVITY TO LINGUISTIC AND DISCOURSE FACTORS IN THE PROCESS OF ANAPHORIC RESOLUTION

The readers' ability to integrate current information with given information has been considered as an important component of reading comprehension process. One aspect of this integration process involves anaphoric resolution. The purpose of this study is to investigate the process of anaphoric resolution, focusing on inferential rigidity of different types of anaphoric ties. Ninety EFL learners were selected from the accessible population of undergraduate EFL students at a university in Iran. In this study an anaphoric resolution test, containing 30 different expository texts, was used. The participants were asked to underline the antecedents of the anaphors. Once the data was collected and scored, it was subjected to a number of appropriate statistical procedures. The Results of the analysis of variance revealed a significant effect of different types of anaphoric ties, F (4, 87) = 10.28, p
Microbial response to enhanced phosphorus cycling in the North Pacific Subtropical Gyre

Microbial community response to nitrogen (N) amendments and induced phosphorus (P) stress was investigated in the North Pacific Subtropical Gyre (NPSG). Samples amended with reduced sources of N, in the form of nitrate plus ammonium, showed significant increases in microbial cell abundance and biomass and decreases in dissolved inorganic phosphate (Pi) and silicate concentrations during an incubation period of 6 d. Primary productivity, P uptake rates (as both Pi and adenosine-5'-triphosphate (ATP)) and alkaline phosphatase activity (APA) all increased following N amendment. Dissolved organic P (DOP) concentrations did not change, but the large increase in APA and ATP uptake rates suggests that DOP was a dynamic pool and an important source for microbial P nutrition in P-stressed samples. Significant changes were also observed in the structure of the microbial community, with Synecho coccus and picoalgae abun- dances increasing substantially in the N-amended treatments, while non-pigmented picoplankton abundances were unchanged. Data on P resource partitioning among groups of picoplankton sep- arated by size using membrane filters of different porosities, or by scattering and fluorescence properties using flow cytometry sorting, indicate that Synechococcus could have a greater role in the NPSG P cycling following episodic N inputs. This experimental manipulation of nutrient load- ing combined with observations at the total population to the microbial group levels constitutes a unique approach to improve our understanding of microbial community structure and function in response to environmental forcing.
Aislamiento y selección de cepas de Trichoderma antagonistas a Sclerotinia sclerotiorum y Sclerotinia minor

Sclerotinia sclerotiorum (Ss) and Sclerotinia minor (Sm) drastically affect more than 400 plant species, and may cause crop yield reductions up to 50%. With the purpose to obtain potential microorganisms to control both pathogens, the isolation of Trichoderma strains from soil samples with different agricultural and forestry use was performed. Seventyone fungal Trichoderma isolates (IBA) were obtained through sclerotia-trap techniques. Subsequently their mycoparasitic activities on mycelium as well as on sclerotia of both phytopathogens were assessed by in vitro dual cultures. The highest percentages of colonization (>90%) of the Trichoderma strains on Ss and Sm were found for the isolates IBA- 3, IBA-4, IBA-38, IBA-54. The ability of Trichoderma strains to parasitize and to degrade sclerotia in general was aggressive for the strains IBA-3, IBA-4, IBA-23, IBA-38, IBA-46, IBA- 54, and IBA-56. Based on morphological criteria, four of the most prominent strains were identified as T. viride (IBA-4), T. pseudokoningii (IBA-23), T. harzianum (IBA-38), and T. virens (IBA-46). These Trichoderma strains have important potential as antagonists to Ss and Sm.
Future changes in surface ozone over the Mediterranean Basin in the framework of the Chemistry-Aerosol Mediterranean Experiment (ChArMEx)

Abstract. In the framework of the Chemistry-Aerosol Mediterranean Experiment (ChArMEx; http://charmex.lsce.ipsl.fr, last access: 22 June 2018) project, we study the evolution of surface ozone over the Mediterranean Basin (MB) with a focus on summertime over the time period 2000–2100, using the Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) outputs from 13 models. We consider three different periods (2000, 2030 and 2100) and the four Representative Concentration Pathways (RCP2.6, RCP4.5, RCP6.0 and RCP8.5) to study the changes in the future ozone and its budget. We use a statistical approach to compare and discuss the results of the models. We discuss the behavior of the models that simulate the surface ozone over the MB. The shape of the annual cycle of surface ozone simulated by ACCMIP models is similar to the annual cycle of the ozone observations, but the model values are biased high. For the summer, we found that most of the models overestimate surface ozone compared to observations over the most recent period (1990–2010). Compared to the reference period (2000), we found a net decrease in the ensemble mean surface ozone over the MB in 2030 (2100) for three RCPs: −14 % (−38 %) for RCP2.6, −9 % (−24 %) for RCP4.5 and −10 % (−29 %) for RCP6.0. The surface ozone decrease over the MB for these scenarios is much more pronounced than the relative changes of the global tropospheric ozone burden. This is mainly due to the reduction in ozone precursors and to the nitrogen oxide (NOx = NO + NO2)-limited regime over the MB. For RCP8.5, the ensemble mean surface ozone is almost constant over the MB from 2000 to 2100. We show how the future climate change and in particular the increase in methane concentrations can offset the benefits from the reduction in emissions of ozone precursors over the MB.
Effects of Blue Tilapia/Channel Catfish Polyculture on Production, Food Conversion, Water Quality and Channel Catfish Off-flavor

Channel catfish (Ictalurus punctatus) monoculture ponds stocked with10,000/ha of mixedsize catfish were compared to ponds stocked additionally with blue tilapia (Tilapia aurea). Ponds stocked with 5000/ha young-of-the-year blue tilapia produced 236 kg/ha less catfish, but tilapia biomass increased by 1020 kg/ha, averaging 233 g/fish. Ponds stocked with sexually mature tilapia in Aprilto provide forage to the catfish had increased catfish production but a poorer food conversion radio. Ponds stocked with sexually mature tilapia in June or July had catfish production and FCR's similar to the controls. Dissolved oxygen was significantly lower than the controls in all polyculture treatments. Zooplankton biomass and secchi disc visbility were significantly lower than the controls in three of four polyculture treatments. Chlorophyll a was slightly, but not significantly, less than the controls. The major benefit of tilapia/catfish polyculture was the reduction of channel catfish off-flavor. Catfish in polyculture treatments were offflavor 8.3% of the times sampled, compared to 62.5% for catfish reared inmonoculture. The addition of tilapia to catfish ponds is a practical, effective means of reducing the incidence of off-flavor inchannel catfish.
Laboratory experiments of current collection to long conductors with geometries relevant to bare electrodynamic tethers

We describe chamber tests of simulated electrodynamic tethers (EDTs) of different geometries operating in a dense, high-speed plasma. The geometries tested and described here were cylindrical and flat-ribbon. Several important conclusions that can be drawn from the tests are as follows: the currents collected by cylinder are close to what would be predicted via orbital-motion-limited (OML) current collection theory. The tape tether had comparable current levels to a theoretical equal area OML cylinder collector. However, I-V behavior clearly is different at nearest distances (∼16λD tape width) as compared to furthest test distances (∼6λD tape width). The tape tether did better than a theoretical equal mass solid cylinder. A “knee” in the I-V curves can be seen in the tape data at a potential that is near the estimated energy of the incoming beam of ions, at least for the closest distances where Debye length is smallest. Below this knee the current increases rapidly as voltage is increased. Above the knee .
The Nurse’s Story: A Qualitative Study Of How Nurses Experience Caring For Patients Who Die Unexpectedly

The primary purpose of this qualitative study was to describe the experience of compassion fatigue among nurse professionals in order to examine natural grieving reactions and how they potentially change nurses’ lives. The focus of this study included nurse professionals working in rural community hospitals in Upstate New York. The nurse professionals in the study were exclusively those who identify and practice as registered nurses (RN). The nurses were asked to share their experiences of repetitive exposure to critical incidents (unexpected outcomes, mass casualties, and/or death of infant/child/young adult). Purposive sampling was utilized as a means to select participants. The researcher collected data by conducting face-toface interviews with each participant. Nurses recalled experiences of high stress caregiving were examined as they relate to critical issues of compassion fatigue, also known as vicarious traumatization, or secondary traumatic stress disorder. After interviewing six registered nurses and analyzing the data, six themes emerged: (a) Sometimes We Do Lose People, (b) You Need to Find Something that Works for You, (c) Too Close to Home, (d) I Care, (e) It’s Not a Job, (f) Self-Preservation, and (g) The Role of Hospital Administration. In addition to the six major themes, there were 14 subthemes. Through this qualitative research, it has become clear to the researcher that nurses make significant sacrifices to ensure the health and well-being of others. They give of themselves to
Association of Radio Polar Cap Brightening with Bright Patches and Coronal Holes

Radio-bright regions near the solar poles are frequently observed in Nobeyama Radioheliograph (NoRH) maps at 17 GHz, and often in association with coronal holes. However, the origin of these polar brightenings has not been established yet. We propose that small magnetic loops are the source of these bright patches, and present modeling results that reproduce the main observational characteristics of the polar brightening within coronal holes at 17 GHz. The simulations were carried out by calculating the radio emission of the small loops, with several temperature and density profiles, within a 2D coronal hole atmospheric model. If located at high latitudes, the size of the simulated bright patches are much smaller than that of the beam size and they present the instrument beam size when observed. The larger bright patches can be generated by a great number of small magnetic loops unresolved by the NoRH beam. Loop models that reproduce bright patches contain denser and hotter plasma near the upper chromosphere and lower corona. On the other hand, loops with increased plasma density and temperature only in the corona do not contribute to the emission at 17 GHz. This could explain the absence of a one-to-one association between the 17 GHz bright patches and those observed in extreme ultraviolet. Moreover, the emission arising from small magnetic loops located close to the limb may merge with the usual limb brightening profile, increasing its brightness temperature and width.
ON HODGES AND LEHMANN’S “6/π RESULT”

While the asymptotic relative efficiency (ARE) of Wilcoxon rank-based tests for location and regression with respect to their parametric Student competitors can be arbitrarily large, Hodges and Lehmann (1961) have shown that the ARE of the same Wilcoxon tests with respect to their van der Waerden or normal-score counterparts is bounded from above by 6/π ≈ 1.910. In this paper, we revisit that result, and investigate similar bounds for statistics based on Student scores. We also consider the serial version of this ARE. More precisely, we study the ARE, under various densities, of the Spearman-Wald-Wolfowitz and Kendall rank-based autocorrelations with respect to the van der Waerden or normal-score ones used to test (ARMA) serial dependence alternatives.
Ornamental Asteraceae Species as New Sources of Secondary Metabolites

Objective: This paper presents the results regarding the morphological characters, the content in total phenols, the metabolites profile and the antioxidant activity of outdoor cultivated Rudbeckia hirta var. Goldilocks and Tagetes erecta plants. Material and Methods: The plant material was represented by flower buds and fully bloomed inflorescences taken from Rudbeckia hirta var. Goldilocks and Tagetes erecta. Morphological assessment was carried using microscopy, while chemical assessment used thin layer chromatography (TLC) and UHPLC methods. The total phenolic content was established with FolinCiocalteu method. The antioxidant activity was evaluated with DPPH radical scavenging tests. The secondary metabolites were evaluated in two different nutritional statuses. Results: The results indicated that the studied ornamental Asteraceae species represent rich sources of phenols. However, the fertilization lowers the plant’s biosynthetic capacity for polyphenols for both Rudbeckia and Tagetes flowers. Thus, by fertilizing, the flowers of Tagetes lose components such as polyphenolic acids, modifying their spectrum. Regarding the antioxidant activity, Tagetes erecta showed a promising activity against free radicals. Conclusion: The concentration of plant secondary metabolites was found to be influenced by the nutritional status. Both species represent a good source for secondary metabolites, but their biological potential remains to be established.
Physicians’ Perspective on Diabetes Mellitus Management within the Context of Personalized Medicine Era in Tabuk Governorate, Saudi Arabia

BACKGROUND: Minimizing the number of therapy failures and decreasing the diabetic complications can be achieved by the application of personalising diabetes therapy, based on patient`s genetics, however, currently, personalised Medicine (PM) in diabetes mellitus management is not extensively applied. AIM: To assess the knowledge, attitudes, and willingness of physicians in practising of PM in diabetes management. METHODS: A cross-sectional analytical study was implemented among 126 physicians from six different governmental hospitals and 12 primary care centres selected by the stratified random sampling technique in the Tabuk region of Saudi Arabia. A structured self-administered questionnaire was utilised for data collection. A simple scoring system (scale of 5 points) was utilised to assess knowledge and willingness. Likert scale was applied to evaluate the attitudes towards practising PM in DM management by the fixed choice response formats. RESULTS: The majority of the participants (97.62%) claimed not receiving any PM and/or genomic medicine training. Most of them (82.54%) expressed unsatisfactory knowledge concerning personalised DM, whereas the medium level of attitudes was reported among 57.14% of them and a good level of willingness had been observed among 76.98% of the physicians. CONCLUSION: Emphasizing on essential personalised DM management knowledge aspects should be given a considerable priority. Fortunately, positive attitudes and goodwill of physicians towards PM are encouraging and should be supported by policymakers.
Study of diversity in a set of lentil RILs using morphological and molecular markers.

We propose the use of SRAP and SSR markers along agronomic or morphological traits in genotypes' differentiation during breeding programs. 25 F5 recombinant inbred lines (microsperma and macrosperma) with good quality characteristics and high yield and a tester were used. All materials were sowed in a randomized block design with 3 replications, at a density of 140 plants per m2. Different morphological traits were recorded and analyzed using ANOVA. Euclidean distances were calculated and a cluster analysis and a principal components analysis (PCA) were carried out. A total of 20 out of 25 SRAP combinations and 9 out of 17 SSR were assayed on the basis of their high polymorphism. Genetic distances were calculated according to Dice's similarity index and a dendrogram was performed. A comparison between morphological and molecular data was carried out through the procrustes generalized analysis. The analysis of variance for morphological traits showed significant differences between genotypes for all variables. The analysis of principal components determined that two PCs explained 75% of the total variation observed among the genotypes and the cluster analysis allowed the conformation of two principal groups. The first one included four varieties belonging to the microsperma type, whereas the second group included all the macrosperma type Rils. Both groups showed differences also in yield and plant height. Molecular analysis showed that 66% out of 273 bands are polymorphic fragments from SRAP markers, indicating a high genetic diversity among Rils. The number of alleles per SSR locus ranged from 3 (SSR 33) to 7 (SSR 156) showing also the variability present. Two exclusive SRAP fragments generated by the combination me5-em1 (230 bp) were found in microsperma group allowing early selection of this trait and all characters associated with it. The correlation between Dice similarity index and Euclidean distance matrices was 87% indicating an excellent consistency between both types of markers and suggested that both types of traits would provide similar estimates on the variability and would be useful to differentiate Rils with similar origin.
Recognition of Amino Acid Motifs, Rather Than Specific Proteins, by Human Plasma Cell–Derived Monoclonal Antibodies to Posttranslationally Modified Proteins in Rheumatoid Arthritis

Antibodies against posttranslationally modified proteins are a hallmark of rheumatoid arthritis (RA), but the emergence and pathogenicity of these autoantibodies are still incompletely understood. The aim of this study was to analyze the antigen specificities and mutation patterns of monoclonal antibodies (mAb) derived from RA synovial plasma cells and address the question of antigen cross‐reactivity.
Effects of Occupational Health and Safety Practices on Organizational Commitment, Work Alienation, and Job Performance: Using the PLS-SEM Approach

Recent occupational accidents urged enterprises to put more importance on occupational health and safety practices. The pressure by both the public authority and the business and social milieu has played an important role in it. The present study investigated occupational health and safety (OHS) practices in five dimensions, i.e. safety procedures and risk management, safety and health rules, first aid support and training, occupational accident prevention, and organizational safety support. A survey form was developed in order to investigate the effect of OHS practices on work alienation, organizational commitment, and job performance as a throughput of such practices. The data set obtained from private sector enterprises was analyzed by structural equation modeling using least squares method. The findings of the analysis suggested that such OHS practices as safety procedures and risk management, safety and health rules, first aid support and training, and organizational safety support had a positive effect on organizational commitment. Moreover, it was seen that safety and health rules and organizational safety support decreased alienation, where first aid support and training played a role in increasing work alienation. Finally, safety procedures and risk management, safety and health rules, and organizational safety support had indirect effects on job performance of the employees.
Advanced high strength steels for automotive industry

The car industry is facing pressure because of the growing demand for more fuel-efficient passenger cars. In order to limit energy consumption and air pollution the weight of the carbody has to be reduced. At the same time, high levels of safety have to be guaranteed. In this situation, the choice of material becomes a key decision in car design. As a response to the requirements of the automotive sector, high strength steels and advanced high strength steels have been developed by the steel industry. These modern steel grades offer an excellent balance of low cost, light weight and mechanical properties.
A Time-Efficient Solution to the General Resource Placement Problem in Cloud

Cloud based large-scale online services are faced with regionally distributed stochastic demands for various resources. With multiple regional cloud data centers, a crucial problem that needs to be settled is how to properly place resources to satisfy massive stochastic demands from many different regions. For the general stochastic demands oriented cross region resource placement problem, the time complexity of existing optimal algorithm is linear to total amount of resources and thus may be inefficient when dealing with a large number of resources. To end this, we propose an efficient algorithm, named discrete function based unbound resource placement (D-URP). Experiments show that in scenarios with general settings, D-URP can averagely achieve at least 97% revenue of optimal solution, with reducing time by three orders of magnitude. Moreover, due to the generality of problem setting, it can be extended to get efficient solution for a broad range of similar problems under various scenarios with different constraints. Therefore, D-URP can be used as an effective supplement to existing algorithm under time-tense scheduling scenarios with large number of resources.
