A study on the awareness, attitudes and performance of teachers towards the organ donation during 2016-2017

Background & Aim: providing an organ for donation is a fundamental issue, but the rate of donation in our country is not favorable. Having awareness, attitude and performance to the organ donation are essential for groups that affected public opinion. The information and knowledge teachers provide for students is the basis for the future attitude toward this topic. The aim of the present study was to examine the awareness, attitude, and performance of teachers toward organ donation. Materials and Methods: the research method was descriptive and cross-sectional. The sample of research were 340 teachers in Torbat-e Heidariyeh in 1396. Data collection instruments were researcher-made valid and reliable questionnaire which was used to assess demographic information, awareness, attitude and performance of individuals. Data were analyzed by using Spss 22 software, descriptive and analytical statistics. Results: the mean age of participants were 41/7±8/01and about 68/2 % of them had bachelor's degree. 91/2 % of them did not participate in the course related to the donation. The mean score of awareness, attitude, and participation were 12/66±2/92, 98/08±10/39and 2/78±1/57 respectively. There were significant relationships among awareness, attitude and teachers performance about organ donation with age, teaching experience, education levels, teaching levels, disciplines of teaching and experience of participation in the course (P <0.05), but there was no significant relationship with gender. Conclusion: despite the average awareness and favorable attitude towards organ donation, unfortunately, there was no proper performance toward donation. This qualification was related to demographic features of individuals. These finding suggesting a focus on educational and advertising program for teachers that play an important role in changing the existing opinion to organ donation in students, families, and society.
Effects of integrated nitrogen fertilization and irrigation systems, rootstocks, and cultivars on productivity, water and nitrogen consumption, and mineral nutrition of pear

Water and nitrogen (N) management are key factors for sustainable pear production in many areas. Effects of integrated N fertilization and irrigation systems, rootstocks, and cultivars on pear (Pyrus communis) mineral nutrition, irrigation water and N consumption, and fruit productivity were investigated on a fine sandy loam soil at Hood River, Oregon from 2005 through 2007. Nitrogen application reduced to 80% of the current broadcast application rate and fertigated in five equal split applications could supply bearing pear trees with adequate N nutrition without reducing soil N reserves. Shifting from the broadcast of dry N fertilizer on soil surface and micro sprinkler irrigation system (BSS) to the split N fertigation and drip irrigation system (FDS) did not affect tree growth, fruit yield, or fruit size of pear. However, FDS produced more Bartlett fruit in color categories of 390 - 417 and 417 - 496 nm than BSS. Irrigation water consumption was reduced by 42.0% to 78.3%, but water use efficiency was enhanced by 51.0% to 264.2% with FDS relative to BSS. Split N fertigation and drip irrigation system may be used as an alternate N fertilization and irrigation system on bearing pear orchards to reduce irrigation water and N consumption in Hood River and other similar areas.
A Cautionary Note on Specification of the Correlation Structure in Inverse-Probability-Weighted Estimation for Repeated Measures

In studies of repeated outcomes, it is customary to account for dependence in the outcomes of a given individual by incorporating a working correlation structure for the individuals outcomes in generalized estimating equations. Inverse-probability weighting is also a common approach used for causal inference and missing or censored data problems in epidemiology. In the absence of inverseprobability weights, it is well known that generalized estimating equations consistently estimate the parameters of a correctly speci ed regression model, irrespective of whether or not the working correlation structure is correct. In this commentary, we show that the situation is quite di¤erent when weights are present, and that regression estimates obtained from generalized estimating equations that are inverse-probability-weighted can be biased, even when the correlation structure is correct. Speci cally, we show that weighted-generalized estimating equations as implemented in Proc GENMOD in SAS can produce biased regression estimates even when modeling bias is absent. We discuss possible strategies to avoid this potential bias and illustrate this phenomenon in an epidemiologic application.
Infl uence of chemical preservatives on the quality and composition indices of raw milk samples

Th e experiment was conducted to assess the feasibility of sodium azide, hydrogen peroxide, bronopol, azidiol, boric acid and potassium sorbate as milk preservatives before estimation of the indicators of the content and quality of raw milk using instrumental methods. Th e milk samples were collected from fresh bulked milk of the dairy farm in Riga District. Milk samples were stored at 4 °C and 20 °C. Untreated milk samples were considered as control samples and were tested against samples treated with 0.02 % sodium azide, 0.06 % hydrogen peroxide, 0.04 % bronopol, 0.4 % azidiol, 1.0 % boric acid and 0.5 % potassium sorbate. Microbiological and chemical parameters (total bacteria count, fat and protein content, somatic cell count) of raw milk samples were measured in all samples just before preservation and then regularly aft er specifi c time interval. Th e results showed that the most suitable preservatives for storing milk before the estimation of the indicators of the content and quality of raw milk by using instrumental methods are bronopol, sodium azide and azidiol. To ensure stable milk quality starting from the time of sample collection till the analysis, it is advisable to preserve the samples with the above-mentioned compounds and storage at 4 °C not longer than 96 hours.
Phylogenetic relationships within and among Brassica species from RAPD loci associated with blackleg resistance

The genus Brassica comprises economically important oilseed and vegetable crops. Their susceptibility to fungal diseases such as blackleg causes yield loss. In this study, thirty accessions from USDA germplasm collection representing two diploid Brassica species (Brassica rapa and Brassica oleracea var. virids) and fifteen tetraploid cultivars (Brassica napus) from the national winter canola variety trials (NWCVT) were evaluated using 13 sets of random amplified polymorphic DNA (RAPD) associated with blackleg resistance in Brassica nigra. 126 highly polymorphic bands with an average of 10 per primer were detected. A UPGMA dendrogram showed B. rapa as highly diverse and was supported from three different basal branches, while B. napus accessions were generally monophyletic. Similarly, all of B. oleraceae accessions were supported from the same basal node. Generally, the three species were reciprocally paraphyletic, suggesting that the RAPD markers showed both functional relationships as well as homology, possibly due to selection at the RAPD loci associated with blackleg resistance. Consequently, two potentially susceptible B. napus accessions were identified. The high polymorphic information content (PIC) and number of phylogenetically informative bands established RAPD as a useful tool for phylogenetic reconstruction, quantification of genetic diversity for conservation, cultivar classification and molecular breeding in Brassica.
Wave equation least square imaging using the local angular Hessian for amplitude correction

Local angular Hessian can be used to improve wave equation least square migration images. By decomposing the original Hessian operator into the local wavenumber domain or the local angle domain, the least square migration image is obtained as the solution of a linearized least‐squares inversion in the frequency and local angle domains. The local angular Hessian contains information about the acquisition geometry and the propagation effects based on the given velocity model. The inversion scheme based on the local angular Hessian avoids huge computation on the exact inverse Hessian matrix. To reduce the instability in the inversion, damping factors are introduced into the deconvolution filter in the local wavenumber domain and the local angle domain. The algorithms are tested using the SEG/EAGE salt2D model and the Sigsbee2A model. Results show improved image quality and amplitudes.
The Effects of Status on Perceived Warmth and Competence Malleability of the Relationship Between Status and Stereotype Content

Research has shown that perceived group status positively predicts competence stereotypes but does not positively predict warmth stereotypes. The present study identified circumstances in which group status positively predicts both warmth and competence judgments. Students (N = 86) rated one of two groups (psychologists vs. engineers) presented as either being low or high in social status on warmth and competence. Results showed that status positively predicted competence stereotypes for both groups, but warmth stereotypes only for psychologists, for whom warmth traits are perceived to be functional in goal achievement. Moreover, for psychologists perceived warmth mediated the relationship between status and perceived competence. Results are discussed in terms of the contextual malleability of the relationship between perceived status, warmth, and competence.
Characterization of Open-Source Applications and Test Suites

Software systems that meet the stakeholders needs and expectations is the ultimate objective of the software provider. Software testing is a critical phase in the software development lifecycle that is used to evaluate the software. Tests can be written by the testers or the automatic test generators in many different ways and with different goals. Yet, there is a lack of well-defined guidelines or a methodology to direct the testers to
intergroup contact effects Enhancing moral virtues : Increased perceived outgroup morality as a mediator of

Research has shown that intergroup contact is one of the most powerful approaches for improving outgroup attitudes. Further, it has been revealed that contact exerts its effects on prejudice reduction mostly by inducing positive affective processes. The present study (N = 146) investigated whether stereotype content enhancement along the core dimensions of competence, sociability, and morality might represent a basic cognitive mechanism driving the contact effects. Results showed that faceto-face encounters with immigrants increased their perceived competence, sociability, and morality. However, only increased perceived outgroup morality mediated the effect of contact on outgroup responses. Our findings extend prior research on the mediators of intergroup contact, showing the key role of perceived morality in driving the contact effects. The importance of these findings for improving intergroup relations is discussed.
VISION BASED OBSTACLE DETECTION IN UAV IMAGING

Abstract. Detecting and preventing incidence with obstacles is crucial in UAV navigation and control. Most of the common obstacle detection techniques are currently sensor-based. Small UAVs are not able to carry obstacle detection sensors such as radar; therefore, vision-based methods are considered, which can be divided into stereo-based and mono-based techniques. Mono-based methods are classified into two groups: Foreground-background separation, and brain-inspired methods. Brain-inspired methods are highly efficient in obstacle detection; hence, this research aims to detect obstacles using brain-inspired techniques, which try to enlarge the obstacle by approaching it. A recent research in this field, has concentrated on matching the SIFT points along with, SIFT size-ratio factor and area-ratio of convex hulls in two consecutive frames to detect obstacles. This method is not able to distinguish between near and far obstacles or the obstacles in complex environment, and is sensitive to wrong matched points. In order to solve the above mentioned problems, this research calculates the dist-ratio of matched points. Then, each and every point is investigated for Distinguishing between far and close obstacles. The results demonstrated the high efficiency of the proposed method in complex environments.
Grapevine rupestris stem pitting-associated virus: A Decade of Research and Future Perspectives

Grapevine rupestris stem pitting-associated virus (GRSPaV), a recently identified virus, is classified as a member of the Foveavirus genus within the Flexiviridae family. The genome of GRSPaV is a single-stranded RNA of positive polarity and encodes five open reading frames (ORFs). ORF1 codes for a replicase polyprotein, which contains sequence domains conserved among Alphavirus-like superfamily of RNA viruses. GRSPaV also encodes three movement proteins, a feature distinct from most plant RNA viruses with a single movement protein. In this communication, we review the advancements that have been made on the virus over the past decade. GRSPaV has been demonstrated to comprise a family of molecular variants. Phylogenetic analyses reveal the presence of at least four distinct variant (lineage) groups. The genome of an isolate representing each of the viral variant groups has been sequenced. It is also demonstrated that commercial grape varieties are usually infected with mixtures of distinct viral variants, whereas rootstock varieties, at least those tested, are infected with a single variant. A specific relationship between some of the viral variant groups and distinct Vitis species seems to exist. Based on available information, a hypothetical model is proposed to explain the possible origin and evolution of different GRSPaV strains. The possible role of GRSPaV in the diseases Rupestris Stem Pitting and Vein Necrosis, as well as its economic importance are discussed. Lastly, we present our views on future directions for GRSPaV research.
A wide diversity of zoonotic intestinal parasites in domestic and stray dogs in rural areas of Kermanshah province, Iran.

Dogs can act as reservoirs, carriers, and transmitters of several zoonotic intestinal parasites that can cause serious health problems for humans. The aim of this study was to determine the prevalence of intestinal parasites in dogs in Kermanshah Province, west of Iran. Faecal samples were collected from domestic and stray dogs from 30 rural areas of Kermanshah province from August 2014 to April 2015 and were analyzed by formalin-ether sedimentation, sucrose otation technique and the modied Ziehl-Neelsen method. Out of 301 dogs examined, 230 (76.4%) were infected with at least one parasite. The incidence on the different types of intestinal parasitic species recovered from domestic and stray dogs are as follows: Toxocara leonina (20.8% and 27.6%), T. canis (7.5% and 9.4%), Taenia spp. (9.2% and 9.4%), hookworm spp. (18.3% and 33.7%), Capillaria spp. (0.8 and 1.7%), Dicrocoelium dendriticum (0.8% and 3.3%), Fasciola spp. (0.8% and 2.2%), Acanthocephal spp. (3.3% and 5.5%), Trichuris vulpis (0.8% and 1.7%), Dipylidium caninum (4.2% and 3.3%), Physaloptera spp. (6.7% and 6.6%), Cryptosporidium spp. (21.7% and 25.4%), Eimeria spp. (35.0% and 34.3%), Giardia spp. (6.7% and 12.7%), Cystoisospora spp. (7.5% and 5.5%), Blastocystis spp. (18.3% and 20.4%) and Sarcocystis spp. (6.7% and 7.2%), respectively. Signicant difference in infection rates was observed between domestic and stray dogs (P>0.05). Hookworm and Eimeria spp. were the most common intestinal helminth and protozoa detected with 83 (27.6%) out of 301 and 104 (34.6%), out of 301, respectively. There was no significant difference in prevalence and distribution of intestinal parasites between male and female dogs (P>0.05). The wide range of zoonotic parasites indicated that people residing in rural areas in Kermanshah province are at risk of exposure to these pathogens. In this respect, appropriate implementation of control programs by public health authorities and veterinarians should be taken into account.
Biomonitoring of Pb and Cd in two impacted watersheds in Southeast Brazil, using the freshwater mussel Anodontites trapesialis (Lamarck, 1819) (Bivalvia : Mycetopodidae) as a biological monitor

Studies were carried out to investigate the contamination of Piracicaba and Mogi-Guacu River basins (Sao Paulo State, Southeastern, Brazil) for heavy metals (Cd and Pb), using the limnic bivalve Anodontites trapesialis as a biological monitor. The results showed that the concentrations of Pb were higher than the control group in both basins, showing the bioavailability of this non-essential element in the basins. The concentrations were higher in the Mogi-Guacu than in the Piracicaba basin, and in the slightly contaminated sites in both basins. There was no correlation between the degree of human impact and Cd and Pb concentrations, it was not possible to infer about concentrations of these heavy metals in the bivalves based only in a broad evaluation of human impact.
Older Adults Map Novel Environments but Do Not Place Learn: Findings From a Computerized Spatial Task

The present study examined older adults' memory for the layout of a novel environment. Young and older adults were trained to find a visible or an invisible target located in a fixed place in a computer-generated (CG) space. All adults relocated a visible target equally well; however, young adults consistently relocated an invisible target whereas older adults did not. With extensive exposure to the CG environment, all adults recalled and reconstructed the layout of that spatial environment equally well. More importantly, however, young adults placed the invisible target within the layout correctly, but the older adults placed the target incorrectly. It is striking that older adults appear to acquire and retain a cognitive map of a novel CG environment despite their continued difficulty in remembering a location within their map.
High-Sensitivity Cardiac Troponin T is Associated with SYNTAX Score and Diabetes Mellitus in Patients with Stable Coronary Artery Disease

High-sensitivity cardiac troponin T (hs-cTnT) and the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score are emerging as important prognostic markers in stable coronary artery disease (CAD). We aimed to investigate the relationship between hs-cTnT and extent and complexity of CAD assessed with STNTAX score. Measurements were obtained from 411 patients with stable CAD (Mean age=61.7 ± 9.9 years, male/female=247/164). The patients were divided into two groups according to the median hs-TnT value (hs-cTnTlow group<9.65 pg/ml and hs-cTnThigh group ≥ 9.65 pg/ml). SYNTAX score values were higher in hs-cTnThigh group compared with hs-cTnTlow group (p<0.05). Hs-cTnT was independently associated with SYNTAX score (β=0.661, p<0.001) and diabetes (β=0.107, p=0.031) in multiple linear regression analysis. The cutoff value of hscTnT obtained by the ROC curve analysis was 9.62 ng/L for the prediction of higher SYNTAX score. In multivariate logistic regression analysis, hs-cTnT, age, diabetes, creatinine and hs-CRP were an independent predictor for higher SYNTAX score. Despite very low circulating concentrations, changes in hs-cTnT concentrations are associated with extent and complexity of CAD and presence of diabetes in patients with stable CAD.

EXTRACTION OF PHENOLIC COMPOUNDS FROM BLUEBERRY ( Vaccinium myrtillus L . ) RESIDUES USING SUPERCRITICAL CO 2 and PRESSURIZED WATER

This work explored the advantages of using subcritical water and supercritical carbon dioxide in the recovery of extracts containing phenolic compounds produced naturally in plants, from the residues of the blueberry (Vaccinium myrtillus L.). Supercritical CO2 and pressurized water are alternatives to the use of toxic organic solvents or methods that apply high temperatures. Belonging to the group of small fruits, blueberries are considered the fruit with the highest antioxidant and polyphenol content, which is present in both peel and pulp. Resveratrol can be used in food and pharmaceutical industries due to its positive biological effects on the human body. Experiments were performed testing the lyophilized and fresh sample, since the compounds of interest present both nonpolar and polar characteristics. Therefore, the water content in the raw material was used to enhance the extraction, working as a co-solvent. The blueberry residues were donated by a juice industry from southern Brazil. Next, the influence of process parameters, such as temperature and pressure was evaluated in the supercritical extraction with CO2 and the study of the behavior of various solvents under various conditions in the pressurized liquid extraction (PLE). The response variables were the global yield, composition and activity of the extracts. Moisture content was determined in the raw material. Antioxidant activity of the residues and extracts was measured using the methods: DPPH and ABTS. Total phenolic compounds were also determined. Anthocyanins were quantified by pH differential method.
Removal of heavy metal ions from aqueous solutions using chemically (Na 2 S) treated granular activated carbon as an adsorbent

Removal of Cd(II), Pb(II), Hg(II), Mn(II), Ni(II) and Zn(II) by chemically (Na 2 S) treated granular activated carbon (GAC) has been found to be concentration, pH, contact time, adsorbent dose and temperature dependent. Adsorption isotherm studies indicated that adsorptive behaviour of metal ions on chemically treated GAC satisfies Langmuir assumptions. Proposed method had potential application for effluent treatment in industries.
Prevalence of Multiple Drug Resistant Escherichia coli in Patients of Urinary Tract Infection Registering at a Diagnostic Laboratory in Lahore, Pakistan

The prevalence and antibiotic susceptibility pattern of E. coli was analyzed in urine samples of patients with acute and recurrent urinary tract infection visiting a diagnostic laboratory in Lahore. The prevalence of MDR strains of E. coli among the isolates was also determined. A total of 310 isolates (73.1%) of E. coli were obtained from 424 positive culture isolates. The highest percentage of the isolates was present in the age group of 51- 75 years in both males and females (30.9% and 9.6% respectively). Females were more frequently affected (77.4%) as compared to males (22.5%, P < 0.02). E. coli showed highest sensitivity towards Imipenem (100%), Meropenem (99.3%), Piperacillin/Tazobactum (96.8%), Amikacin (89.7%), Cefoperazone/Sulbactum (86.8%), Ceftazidime (77.2%), Gentamicin (73.2%), and Aztreonam (67.1%). 65.5% of isolates were resistant to more than 8 drugs, belonging to 3 or more than 3 different classes of drugs.
