An investigation into the consequences of selection for growth, size and efficiency.

The effect of selecting for growth, size and efficiency on fitness (fertility and survival rate) and body composition was investigated by surveying a number of selection experiments which have appeared in Animal Breeding Abstracts since 1938. In the case of rodents and poultry, selection for body mass, growth rate and feed efficiency was studied in 26, 21 and 13 experiments respectively. Much less information on the relationship between growth, size or efficiency and fitness is available for beef cattle and mutton sheep. When selecting for increased body mass or growth rate in rodents and poultry, almost 90% of the experiments yielded data which demonstrated an increase in body fat, or a decrease in fitness, or both in the offspring. When selecting for increased feed efficiency, only 15% of the experiments surveyed reported un favourable results. In general, the relationship between growth rate or body mass and fertility in beef cattle tends to be negative. Animal breeding for meat should therefore not be based on selection for growth or size alone. Other selection criteria should be investigated and the principle of utilizing sire and dam lines in beef cattle should receive attention. 'n Ondersoek na die invloed van seleksie vir groei, grootte en voerdoeltreffendheid op fiksheid (vrugbaarheid en oorlewing) en liggaamsamestelling is uitgevoer deur seleksie-eksperimente te bestudeer wat sedert 1938 in Animal Breeding Abstracts verskyn het. By knaagdiere en pluimvee is 26, 21 en 13 seleksie-eksperimente vir onderskeidelik massa, groeitempo en voerdoeltreffendheid bestudeer. Baie minder inligting oor die verwantskap tussen groei, grootte of voerdoeltreffendheid en fiksheid is vir vleisbeeste en -skape beskikbaar. Met seleksie vir 'n hoer liggaamsmassa of groeitempo by knaagdiere en pluimvee het ongeveer 90% van die eksperimente 'n toename in liggaamsvet of 'n afname in fiksheid of beide getoon, in vergelyking met 15% wanneer vir 'n beter voerdoeltreffendheid geselekteer is. Dor die algemeen neig die verwantskap tussen groeitempo of liggaamsmassa en vrugbaarheid by vleisbeeste om negatief te wees. Vleisdierteelt kan dus nie net op seleksie vir groei of grootte gefundeer word nie. Ander seleksiekriteria behoort ondersoek te word en die beginsel van die gebruik van vader- en moederlyne by vleisbeeste behoort oorweeg te word .
The effect of some chemical materials against virulence factors of Candida ssp isolated from UTI patients

During the period from September 2016 to December 2017, a total of 135 urine samples were collected from urinary tract infection patients attending to AL-Zahraa Hospital in AL-Najaf Governorate. The present study was conducted to isolate and identify Candida spp. isolated from urinary tract infection patients by different methods including direct examination , laboratory culture , biochemical test and by modern techniques (Api Candida kit) and determine the virulence factors phenotypic to Candida spp which involved (bio film formation, phospholipase and germ tube). The percentage of females to males was as following , female (84) 62.2 % (21) infected and male (51) 37.8% (1) infected with all age categories. The results in this study are explain that is some Candida spp. such as C. albicans, have high susceptible to eugenole follow by phenol and umbellulone. The efficiency of some chemical substances such as (eugenole, umbellulone, and phenol) was evaluated to inhibit the growth of Candida s sp as well as some virulence factors such as bio film formation, germ tube and phospholipase which were studied in this research. Statistically analysis results have been significance difference between the results of the substance concentrations and the concentrations of the different other substances.
Astronaut Visual Tracking of Flying Assistant Robot in Space Station Based on Deep Learning and Probabilistic Model

Real-time astronaut visual tracking is the most important prerequisite for flying assistant robot to follow and assist the served astronaut in the space station. In this paper, an astronaut visual tracking algorithm which is based on deep learning and probabilistic model is proposed. Fine-tuned with feature extraction layers’ parameters being initialized by ready-made model, an improved SSD (Single Shot Multibox Detector) network was proposed for robust astronaut detection in color image. Associating the detection results with synchronized depth image measured by RGB-D camera, a probabilistic model is presented to ensure accurate and consecutive tracking of the certain served astronaut. The algorithm runs 10 fps at Jetson TX2, and it was extensively validated by several datasets which contain most instances of astronaut activities. The experimental results indicate that our proposed algorithm achieves not only robust tracking of the specified person with diverse postures or dressings but also effective occlusion detection for avoiding mistaken tracking.
Factors Associated with Dietary Diversity among Children of Agro Pastoral Households in Afar Regional State, Northeastern Ethiopia

Introduction: Dietary diversity has been consistently associated with child nutritional status and growth in developing countries. Therefore, this study was aimed to identify the factors affecting dietary diversity among children of agro pastoral households in northeastern Ethiopia. Methods: A community-based cross sectional study was employed in Afambo district on 370 mother-child pairs. Binary and multivariable logistic regression analyses were used to identify the factors associated with dietary diversity. Variables with a p-value < 0.05 were identified as statistically significant. Results : Overall 30.8% (95% CI: 26.1, 35.5%) of children aged 6-59 months achieved the minimum dietary diversity score (DDS) with mean score of 2.73. Mothers who got counseling on proper child feeding practices at postnatal checkup [AOR=3.7(1.45, 9.28)] and mothers who fed colostrum to their children were independent positive predictors of meeting minimum dietary diversity. The factor associated with decreased odds of meeting minimum dietary diversity was moderate to severe household hunger scale [AOR=0.24(0.10, 0.57)]. Conclusion: This study showed that nearly three children in every ten achieved the minimum DDS. Therefore, sound and culturally appropriate child feeding counseling during postnatal care should be given to mothers of young children so that they can make the possible use of locally available foods. In addition, expansion of social programs that might contribute to the earning capacity of poor households is also vital to ensure the dietary diversity.

A Framework for Teaching Practice-Based Research With a Focus on Service Users

ABSTRACT The integration of research and practice in social work education and agency practice is both complex and challenging. The analysis presented here builds upon the classic social work generalist framework (engagement, assessment, service planning and implementation, service evaluation, and termination) by developing a three-part framework to capture practice, research, and service user involvement. The article also includes a case vignette to illustrate the application of the framework. The evolution of practice-based research provides a venue for these integration issues, with special attention to the role played by service users. The analysis concludes with a series of questions to guide evolving practice and future research.
Situating approaches to museum guides for families and groups

In this paper, we analyze the current state of museum guide technologies and applications in order to develop an analytical foundation for our future research in an adaptive museum guide for families. We have focused our analysis on three critical areas of interest in considering group and social interaction in museums: tangibility, the role of tangible user interfaces; interaction, visit types and visit flows; adaptivity, user modeling approaches.
δO and Controlling Factors on the Pearl River Basin and Adjacent Regions

Based on the precipitation δ18O values from the datasets of the Global Network of Isotopes in Precipitation (GNIP), the National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR) Reanalysis data, and previous researches, we explored the temporal and spatial variations of precipitation δ18O in a typical monsoon climate zone, the Pearl River basin (PRB), and adjacent regions. The results showed that the temporal variations of precipitation δ18O for stations should be correlated with water vapor sources, the distance of water vapor transport, the changes in location, and intensity of the intertropical convergence zone (ITCZ) rather than “amount effect. ” Meanwhile, local meteorological and geographical factors showed close correlations with mean weighted precipitation δ18O values, suggesting that “altitude effect” and local meteorological conditions were significant for the spatial variations of precipitation δ18O. Moreover, we established linear regression models for estimating the mean weighted precipitation δ18O values, which could better estimate variations in precipitation δ18O than the Bowen and Wilkinson model in the PRB and adjacent regions.
Eye Detection with Faster R-CNN

The accuracy of eye detection is crucial to a variety of biometric identification technologies, such as iris recognition. The challenge of eye detection comes from improving accuracy of detection in the case of occlusion or reflection of glasses. In this paper, an eye detection method based on Faster Region-based Convolutional Neural Network (Faster R-CNN) is proposed. The method includes three import parts: convolutional layers, region proposal network (RPN) and detection network. By training monocular and binocular models on the training dataset, the recall of monocular and binocular models on test dataset can reach 96% and 95% respectively, which proves that the proposed method based on Faster R-CNN has high accuracy of detection in the task.
The Position and Orientation Measurement of Gondola Using a Visual Camera

The research of automation and robotics in building construction industry could improve working conditions through applications which create safety hazards for humans. In this paper, we propose an approach to sense a gondola robot system using a vision camera. To control a gondola safely and accurately, some parameters should be measured such as translation in X, Y and Z axis and rotation (Euler angles) of the gondola. Our approach conducts this operation with inexpensive and easy-to-maintain system.
Climate Change Adaptation in the Southwest Indian Ocean: Case Study of the Perception of Risk, Common Coping Strategies and the Potential for Micro-Insurance

Given that climate change is adversely impacting upon the agriculture and tourism industries and the low income labourers in these sectors, this paper reports on household perceptions of climate risks, current coping mechanisms and current coverage of insurance in Mauritius and the Seychelles. The research methodology included a survey of 586 persons, interviews and workshops with stakeholders in the agricultural and tourism sectors of each country. Approximately 42% of persons surveyed had experienced some loss from an extreme weather event, with some respondents experiencing multiple events. The results demonstrated a reliance on personal savings and government assistance as a form of pseudo-insurance, with as many as 65% of respondents indicating that they utilized savings to cope after an extreme weather event which damaged housing and livestock. The general feedback from interviews in Mauritius indicated that government aid is usually provided to the identified sectors when they are impacted by disaster events. For Seychelles, however, government support was less prevalent. The use of such asset depleting coping mechanisms forebode the distinct possibility of having to sell possessions or not repair at all should there be future catastrophe events. These findings advance a sound agenda for policy and practice in the Indian Ocean on matters related to climate change adaptation. By discussing the current status of climate risk awareness and resilience in these countries, this paper offers an argument for the inclusion of microinsurance in a comprehensive risk management plan as an alternative financial risk management tool. Introducing microinsurance products designed specifically for climate and weather risk, and which take into account the shortcomings of traditional insurance, may reduce the vulnerability of coastal communities in the face of climate change.
3D STRCUTURAL MODELLING FOR PROCATECHUATE 3, 4 DIOXYGENASEFROMPSEUDOMONASCEPACIABASEDONTEMPLATE OF M CHAIN FROM P. AERUGINOSA

The 3D model of Protocatethuate 3,4 dioxygenase beta chain from Pseudomonas cepacia was built, based on X-ray crystallographic structure of Protocatethuate 3,4 dioxygenase M chain from Pseudomonas aeruoginosa. Dioxygenase catalyses the cleavage of molecular oxygen with subsequent incorporation of both oxygen atoms into organic substrates. Some of the dioxygenase from bacteria catalyse critical ring-opening step in biodegradation of aromatic compounds. These bacterial enzymes contain non- heme ferric iron as the sole cofactor. Protocatethuate 3,4 dioxygenase (3,4PCD) was one of such enzyme recognized which catalyses the intradiol cleavage of protocatechuic acid by oxygen to produce â- carboxy –cis-cis-muconic acid. Studies on 3,4(PCD) found in Pseudomonas aeruginosa is an oligomer with relative molecular mass (587K). The homology modelling is done based on the programmes to annotate protein sequence aligment with 3D structural features which helps to understand the conservation of amino acids in the specific local environment.
Light induced electrical and macroscopic changes in hydrogenated polymorphous silicon solar cells

We report on light-induced electrical and macroscopic changes in hydrogenated polymorphous silicon (pm-Si:H) PIN solar cells. To explain the particular light-soaking behavior of such cells - namely an increase of the open circuit voltage (Voc ) and a rapid drop of the short circuit current density (Jsc )- we correlate these effects to changes in hydrogen incorporation and structural properties in the layers of the cells. Numerous techniques such as current-voltage characteristics, infrared spectroscopy, hydrogen exodiffusion, Raman spectroscopy, atomic force microscopy, scanning electron microscopy and spectroscopic ellipsometry are used to study the light-induced changes from microscopic to macroscopic scales (up to tens of microns). Such comprehensive use of complementary techniques lead us to suggest that light-soaking produces the diffusion of molecular hydrogen, hydrogen accumulation at p-layer/substrate interface and localized delamination of the interface. Based on these results we propose that light-induced degradation of PIN solar cells has to be addressed from not only as a material issue, but also a device point of view. In particular we bring experimental evidence that localized delamination at the interface between the p-layer and SnO2 substrate by light-induced hydrogen motion causes the rapid drop of Jsc.

It discusses How are the institutional policies on the doctoral dissertation defense different across Canadian universities? ; What do these differences imply about the role, function, and purpose of the oral defense in the PhD examination in Canada? ; and How might these differences inform PhD education in Canada? It concludes with a call for academics and students’ awareness of these variations in policy and practice.
A Finite element model for thermal dilatation of carbon nanotubes

The paper presents a finite element model that can be used for modelling of a nanotube thermal contraction with temperature increase. Since carbon nanotubes exhibit anisotropic thermal contraction, the ordinary structural mechanics approach based on the beam finite elements acting as interatomic bonds cannot be directly applied. To circumvent this problem, a set of additional rod elements is introduced into the model. If different coefficients of thermal expansion are used for the beam and rod elements, anisotropic thermal contraction can be modelled. An exact calculation procedure for these thermal expansion coefficients is presented. The proposed model is tested on one carbon nanotube and results are compared to the data available in literature. Influence of the stiffness of additional rod elements on the obtained results is not noticed.
The Character Educators of Future: What Do They Know? What Do They Need?

Providing the wholistic development of individual in terms of personal and psychological characteristics guiding our actions with educational processes forms “the character education”. Teachers as an important figure in this process should be aware of character education and what they are responsible for. To achieve this, teacher education should include the essentials of character education and prepare teachers for their inevitable role within their professional life. This study aimed to reveal what the pre-service primary school teachers know about character education and what their needs through their education for becoming a character educator are. The participants were pre-service teachers from primary school education department in Cukurova University. The data was collected with an open ended quesitonnaire and analyzed using content analysis. According to findings, it is obvious that pre-service teachers are mostly aware of the importance and content of character education and they see what their future roles are. They came up with many recommendations for teachers and teacher education. This study is thought to be beneficial in terms of revealing the situation within pre-service teachers regarding character education awareness and also helping teacher educators to see what pre-service teachers need to be efficient character educators.

Do Older Bilinguals Tell Better Stories

Efforts to understand changes in language development and variations in language production across lifespan have increased considerably in the past several decades (Sankoff, 2017). In narrative discourse production, although several studies have reported age-related differences, the findings are not consistent. Additionally, previous research has investigated age-related changes in discourse production either with monolingual participants or with bilingual participants cross-linguistically in their first and second languages. This case study attempts to investigate age-related changes in narrative speech produced by six bilinguals aged between 6 and 53 years in L3-English. The narratives produced by the participants were analyzed with respect to quantity, informative content and narrative cohesion. The findings obtained on each of the measures showed increase in fluency and informative content, yet a fluctuation in cohesion across age.
OPTIMIZATION OF FERMENTATION MEDIA FOR THE GROWTH OF A FUNGUS USED AS BIOHERBICIDE

In this work was optimized the composition of fermentation media for the growth of Phoma sp. , which is a potential fungi to be used for the production of bioherbicide. For this purpose, the fungal growth was optimized, firstly, using synthetic media containing glucose, peptone and yeast extract. In a second moment, glucose was changed by sucrose food-grade and peptone and yeast extract by corn steep liquor and the growth optimized again. The optimized composition of synthetic media was glucose and peptone 20 g.L -1 , yeast extract 7.5 g.L -1 and initial pH of 6.0. For industrial media, the optimized composition was sucrose 20 g.L -1 , CSL 8% and initial pH of 6.0. At these conditions, maximum fungal biomass were 22 and 33 g.L -1 , respectively. This study shows that industrial medium was better than synthetic medium and provides cost savings for a possible increase in production scale.
Comorbidity of depressive and anxiety disorders

The authors present the problem of comorbidity of anxiety disorders and depressive disorders. Although anxiety is one of the most common concomitant symptoms of depression, International Statistical Classification of Diseases and Related Health Problems (Tenth Revision) and Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) classifications do not mention it among diagnostic criteria of depressive disorders. Comorbidity of those medical states is associated with more severe clinical course and greater drop-out risk. Generalized anxiety disorder is the most common comorbid anxiety disorder accompanying major depressive disorder. The latter is — on the other hand — the most prevalent complication of obsessive-compulsive disorder. Pathogenesis of the comorbidity of anxiety disorders and depressive disorders is explained by neuroendocrine, monoamine and psychological models. Data on the comorbid anxiety and depressive disorders is relatively scarce. Therapeutic strategies used in these conditions can be divided into sequential and concurrent ones.

Nie umknęło ono uwadze Hipokratesa (IV w. p.n.e.), który zanotował: „Jeśli lęk i strapienie trwają długo, to jest to melancholia”. Istotne miejsce lęku w przeżyciach człowieka pogrążonego w depresji podkreślał również Plutarch (50–125 r. n.e.): „[W melancholii] najmniejsze zło wyolbrzymia się pod wpływem lęku; człowieka czeka najgorszy los. ” [1]. Mimo że współcześni autorzy twierdzą, że lęk — obok symptomów nadużywania substancji psychoaktywnych i zaburzeń osobowości — należy do objawów najczęściej towarzyszących depresji [2–4], to obecnie obowiązujące systemy klasyfikacyjne zaburzeń psychicznych — International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) oraz Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) nie uwzględniają lęku w opisach zaburzeń afektywnych. Wyłączenie lęku spośród kryteriów rozpoznawczych tych zaburzeń było podyktowane względami metodologicznymi — było ono warunkiem zapewnienia rozdzielności kryteriów [5, 6]. Widać wyraźnie, że pytanie o to, czy występowanie nasilonych objawów depresji i lęku wskazuje na obecność dwóch niezależnych procesów chorobowych, czy też jednego procesu owocującego dwoma rodzajami symptomów, nadal czeka na wiążącą odpowiedź. Pomimo tych niejasności nozologicznych problem współwystępowania zaburzeń depresyjnych i lękowych wiąże się z wieloma istotnymi następstwami. Współwystępowanie depresji i lęku ma związek
