Perennial ryegrass and novel festulolium forage grasses in the tropical highlands of Central Kenya: Preliminary assessment
Authors: Mwendia Solomon Waweru , Maass Brigitte , Njenga David , Notenbaert An
Published: July 2019

Two perennial ryegrass (Lolium perenne) varieties and 5 festulolium hybrids (L. perenne × Festuca spp.) were evaluated on-farm for their performance over one growing season on clay loam soils at Ol-joro-Orok in the central highlands of Kenya at about 2,600‒2,800 masl. Seed was sown in May 2015 and fertilizer (90 kg N + 90 kg P/ha) was applied at planting. The study continued for 8 months with harvests after 113, 99 and 32 days (3 growth cycles). Growth attributes assessed included dry matter yield (DMY) and plant height, while forage nutritive value was measured in terms of crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) concentrations. At the end of the first growth cycle, 61 local dairy farmers rated the grasses on criteria they nominated as being important, including DMY, growth rate, height, frost tolerance, disease tolerance and leafiness. Total herbage yields for the whole study period (8 months) ranged from 14.6 to 18.0 t DM/ha for perennial ryegrass and 14.3 to 20.9 t DM/ha for festulolium with very poor growth in the third growth cycle. All perennial ryegrass and festulolium lines contained similar (P>0.05) concentrations of CP (163–190 g/kg DM), ADF (264–281 g/kg DM) and NDF (448–493 g/kg DM). For perennial ryegrass, farmers gave a minimum weighted score of 6.7 and for festulolium, 7.9. Based on herbage production, forage nutritive value and farmers’ assessments, we conclude that all perennial ryegrass and festulolium lines tested have the potential to contribute to improving the forage resource base in this and other similar areas, especially for farmers whose land sizes allow grazing instead of stall-based feeding only. Further studies with N applications after each harvest would determine whether yields can be maintained at high levels for longer than in this study, while grazing and feeding studies would determine how well the pastures support weight gains and milk yields. Studies over a number of years are needed to assess how persistent these varieties/hybrids are in this and other environments.

Authors: Melehin A. , Sergienko E.A.
Published: July 2019

The article shows that in comparison with people aged 55-60 years in the groups of 61-74 and 75-90 years there are symptoms of age-specific socio-cognitive deficits in the recognition of emotions: changes in response time to emotional stimulus in the direction of slowdown; difficulties in fine differentiation of emotions of joy and sadness; the effect of high emotional intensity for a more accurate definition of emotions; cognitive shift in attention and interpretation of socio-emotional information. At a later age, there is a combined cognitive bias in the recognition of emotions in the face. More dominated bya positive shift. Unlike people 75-90 years in groups 55-60 and 61-74 years better recognize emotions of fear and sadness, than 75-90 years. It is more difficult to recognize anger at a later age. The lack of definition of neutral emotional expressions, which is accompanied by the phenomenon of depressive displacement, is described. General and age-specific predictors of recognition and differentiation of emotions in the face at a later age are identified.

Authors: Şentürk Cihad , Zeybek Gülçin
Published: July 2019

The objective of this research is to examine the relationship between teachers’ teaching-learning conceptions and pedagogical competence perceptions and to reveal the related findings. The research was designed in the relational survey model. The study group of the research is composed of teachers who work in elementary and secondary public schools in Karaman district of Turkey (n = 223). In the research, it was found that there are positive or negative relationships between teachers’ teaching-learning conceptions and pedagogical competence perceptions sub-dimensions. In addition, according to regression analysis, it was seen that the model was significant as a whole and teachers’ teaching-learning conceptions and pedagogical competence perceptions were significantly associated. It was understood that the teachers’ teaching-learning conceptions explained 42% of their pedagogical competence perceptions. According to the findings of the research, it was observed that teachers mostly had traditional teaching-learning conceptions and there was no significant relationship between their traditional teaching-learning conceptions and their pedagogical competence perceptions except the first dimension. It was found that there was a significantly positive relationship between their teaching-learning conceptions and their pedagogical competence perceptions among teachers who have constructivist teaching-learning conception. According to these findings, teachers’ pedagogical competence perception levels decrease as their teaching-learning conceptions move towards the traditional conceptions, and pedagogical competence perception levels increases as their teaching-learning conceptions move towards constructivism. When all these results are taken into consideration, teachers should be educated in accordance with the constructivist teaching-learning conception in line with their contemporary educational philosophies, models and conceptions.

Authors: De Jesus Samuel José Amaral
Published: July 2019

A presença de água livre é um dos grandes fatores que interfere na deterioração dos alimentos, visto que facilita o crescimento microbiano. Diante disso, é necessário adotar métodos que colaborem para a conservação dos diversos produtos, a fim de que os mesmos possam ser comercializados e usados por mais tempo. O abacaxi é um dos frutos mais produzidos e consumidos no país, sendo utilizado para diversas finalidades, como geleias, vinagre, caldos, pedaços cristalizados, e outras. Colabora na prevenção de infecções, no controle de glicose do sangue, previne diversas enfermidades. Quando não consumido in natura, geralmente se usa a fruta desidratada, a fim de que a presença de água não venha a deteriorar o alimento. Esta pesquisa tem como objetivo analisar o processo de desidratação do abacaxi, a partir da observação das mudanças que ocorrem na fruta, com destaque à atividade de água, relacionando temperatura e umidade. Foi possível observar a redução da umidade de 87% para 60%, em intervalos determinados de 10 e 15 minutos. Quando a temperatura  aumenta, ocorre a perda de água e a consequente desidratação, que diminui a atividade e ajuda a conservar as características do abacaxi, estas semelhantes ao alimento fresco. Palavras-chave: Abacaxi. Atividade de Água. Desidratação. AbstractThe presence of free water is one of the major factors that interferes with the deterioration of food, since it facilitates microbial growth. In view of this, it is necessary to adopt methods that collaborate for the conservation of the various products, so that they can be commercialized and used  longer.

Published: July 2019

Many women in developing countries are dying from preventable causes related to pregnancy and childbirth. These maternal deaths are attributed to the poor coverage of reproductive health services and high fertility levels. A holistic review of the reproductive health is necessary to reflect the country’s situation and progress of reproductive health and provide recommendations for areas that need an improvement. The aim of this paper is to provide an overview of the historic development of maternal mortality and fertility in Myanmar during the past 25 years, focusing on the antenatal care (ANC) coverage, deliveries attended by skilled persons, and contraceptive use. All published nationally representative data were compiled, and trend analysis was performed. The maternal mortality ratio declined significantly by 9.1 (95%CI: 4.0-14.1) maternal deaths per 100,000 live births/year between 1990 and 2015, but it failed to achieve the target of Millennium Development Goals 5. There was no significant improvement in ANC coverage and care during delivery. Contraceptive use increased significantly, leading to a reduction in the total fertility rate. Nevertheless, overall reproductive health failed to reach a satisfactory level. Maternal mortality still remains high. Thus, there is a need to improve service coverage and more so in the regions with poor performance to reduce the high maternal mortality.

Sympoetics of Place and the Red Dust of India
Authors: Berry Alex
Published: July 2019

Experimenting with forms that lie outside the boundaries of traditional ethnographic research, in this paper I think with Haraway’s (2016) notion of sympoiesis as a platform to reimagine my engagements with place after recently returning home from my pedagogical work as visiting artist-researcher-teacher at a school in Goa, India. I imagine sympoetics as methodological engagement that conceives poetry, not as a purely individual, reflective practice, but rather a co-compositional performance that attends to the polymorphic, often contradictory relations of humans and materials as they are entwined with place. Following the ephemeral movements of India’s red dust, I attend to the intersections of seemingly disparate materials, specifically a child’s pencil and waste materials, and the ways in which they gather meaning together/apart among local/global red dust assemblages. By highlighting and decentering colonial undertones in ethnographic methodology with children and attending closely to anticolonial stories told through my relations with the red dust of India, this paper works to both sit with—and stir up—discomfort, toward more complex, contentious, and responsive accountabilities with place. Using sympoetics to trace the movements and impermanence of red dust, this performance is intentionally partial and aims to situate research in the midst of “not yet” and unknowability.
Inhibition of TLR4/TRIF/IRF3 Signaling Pathway by Curcumin in Breast Cancer Cells
Authors: Güney Eskiler Gamze , Deveci Özkan Asuman , Kaleli Süleyman , Bilir Cemil
Published: July 2019

Purpose: Toll-like receptor 4 (TLR4) is over-expressed in breast tumors and thus contributing to the tumor progression and metastasis. Natural products have drawn attention in cancer immunotherapy due to their various biological activities. Curcumin is well investigated in different types of cancer. However, the mechanisms underlying its anti-inflammatory actions have not been extensively elucidated.  For this purpose, we explored the inhibitory effects of curcumin on lipopolysaccharide (LPS)-induced TLR4 dependent TRIF signaling pathway in two subtypes of breast cancer cell lines (MCF-7 and MDA-MB-231) in this study. Methods: In this context, the cytotoxicity of curcumin and LPS alone and the combination of curcumin with LPS on these cells was evaluated by WST-1 assay.  The expression level of TLR4 and the release of type I interferon (IFN) levels were determined after treatment with curcumin and/or LPS by RT-PCR and ELISA analysis, respectively. Furthermore, the subcellular localization of TLR4 and interferon regulatory factor 3 (IRF3) were detected by immunofluorescence analysis. Results: Curcumin treatment suppressed breast cancer cells viabilities and the activation of TLR4-mediated TRIF signaling pathway by the downregulation of TLR4 and IRF3 expression levels and the inhibition of type I IFN (IFN-α/β) levels induced by LPS. However, curcumin was more efficient in MDA-MB-231 cells than MCF-7 cells owing to its greater inhibitory efficacy in the LPS- enhanced TLR4 signaling pathway. Furthermore, IFN-α/β levels induced by TLR4 and IRF3 were decreased in these cells following curcumin treatment. Conclusions: Consequently, these results demonstrated that the activation of LPS stimulated TLR4/TRIF/IRF3 signaling pathway was mediated by curcumin in breast cancer cells, in vitro. However, more studies are necessary to examine the curcumin’s anti-inflammatory activities on TLR4/MyD88/NF-κB as well as other signaling pathways downstream of TLRs in breast cancer.
DYNAMICS OF ILLUMINANCE INCIDENT ON THE LANW SURFACE IN THE SHADE OF VARIOUS WOODY SPECIES
Authors: Grechushkina‐Sukhorukova L. A.
Published: July 2019

Aim. This paper is aimed at studying the relative light conditions (RLC) for lawns in the crown shade of light‐requiring and shade‐tolerant trees from the landscaping sites of Stavropol.

Methods. The illuminance incident on the lawn surface was measured using a TKA‐LUX light meter from 7 a.m. to 5 p.m., every two hours.

Results. It is shown that lawns under the crowns of light‐requiring tree species (Larix sibirica), received the highest RLC. During three calendar periods (22.05–15.06–18.09.2017, from 7 a.m. to 5 p.m.), its value amounted to 8.2‐9.2% (9.2% – at 1 p.m.); 4.6‐6.8% (6.8%); 7.0‐12.9% (12.9%). The projective cover of the lawns reached 75‐90%. In case of Betula pendula, the RLC values were as follows: 2.6‐3.7% (3.7%); 1.9‐3.2% (3.0%); 3.6‐5.7% (5.6%), with the projective cover amounting to 75‐90%. Under the crowns of shade‐tolerant species, Abies nordmanniana, the RLC values reached 1.0‐1.5% (1.0%), 0.6‐1.5% (0.6%), 0.7‐3.0 (0.7%), with the projective cover of lawns amounting to 10‐25%. For Aesculus hip‐ pocastanum, these values were equal to 0.6‐0.8% (0.6%); 0.6‐0.8% (0.6%); 9.0‐11.5% (11.2%), with dead patches being frequently formed. Projective cover values for shaded lawns correlate with the RLC value (r = 0.89).

Conclusions. Under present conditions, ground covers consisting of Vinca minor shrubs and Hedera helix vines can be used in urban greening for intensively shaded sites.
Сhoosing the Belt Conveyor Start Mode
Authors: Metelkov Vladimir P. , Liberman Yakov L.
Published: July 2019

The paper is concerned with the problems associated with starting a long conveyor driven by an induction motor. We consider the dynamic loads in the conveyor belt during start-up, which cause slippage of the conveyor belt on the traction drum leading to its premature deterioration. The relevance of the topic is associated with the high cost of the conveyor belt reaching 60% of the cost of the entire conveyor and more. The aim of the work is to ascertain the possibilities of reducing the wear of the conveyor belt, for example, through the use of the possibilities provided by the system of the electric drive. The possibility of reducing the probability of the conveyor belt slippage by increasing the initial belt tension is noted. However, constant high tension also accelerates belt deterioration. To solve this problem, the use of automatic tension control devices is proposed, as well as the reduction of dynamic loads in the belt by using soft starters based on a thyristor voltage converter, which regulates the amplitude of voltage on the motor stator. The features of an asynchronous motor heating when starting with a constant speed of rotation of the magnetic field are discussed. The interrelation between the start-up duration and the motor stator winding heating with the dynamic loads occurring in the conveyor belt in start-up modes is considered. Modeling results obtained using the Simulink package are presented. Since long start-up modes of asynchronous electric drives based on thyristor voltage converters can lead to motor overheating, especially when the conveyor is restarted under full load and in hot climates, it is advisable to use automatic conveyor belt tension control devices during start-up modes thereby reducing premature belt deterioration together with a decrease in the conveyor motor heating.

Novelty/Originality: For the first time, hours devoted to the study of law subjects; unsatisfactory qualification of teachers in the legal course; lack of systematic educational and methodical literature, and documentation has been studied.
An Examination of Emotion Regulation and Associated Factors in Attention Deficit-Hyperactivity Disorder
Authors: BAYKAL Saliha , NALBANTOGLU Ayşin

Aim

Emotion regulation difficulties
(ERD) such as anger, irritability and frustration intolerance leading to severe
functional losses may be observed in attention deficit-hyperactivity disorder
(ADHD). The purpose of this study was to compare children and adults diagnosed
with ADHD and a healthy control group in terms of emotion regulation
characteristics and to examine factors potentially associated with ERD.

Method

The study was performed with 72
children/adults aged 6-18 diagnosed with ADHD based on DSM-V diagnostic
criteria at the XXXXXX Child and Adolescent Psychiatry Polyclinic, Turkey, and
30 healthy controls. The Schedule for Affective Disorders and Schizophrenia for
School-Age Children – Present and Lifetime Version (K-SADS-PL), a
semi-structured interview form, was used to determine comorbidities. ERD scores
(ERD=attention+anxiety/depression+aggression subscales) were determined using
the Childhood Behavior Checklist (CBCL).

Results

Mean ERD scores were 189.45±19.33
in the ADHD group and 164.13±9.94 in the healthy control group. A significant
difference was determined in ERD scores between the two groups (p˂0.001**).
When the ADHD group was evaluated in terms of clinical characteristics,
comorbid psychiatric disorders were not associated with ERD, but combined type
ADHD characteristics emerged as significant predictors for ERD (r=0.43,
r2=0.18, p=0.001**).

Conclusion

The results of this research revealed
significantly greater ERD in individuals diagnosed with ADHD compared to
healthy controls, and that combined type ADHD is a predictor for ERD. Since ERD
accompanying ADHD lead to greater function loss in the individual and are
associated with persistence of the disorder in adulthood, these are important
clinical characteristics also requiring evaluation during the diagnosis and
treatment of ADHD.

The effect of age at first calving (AFC) and various non-genetic factors i.e. season of calving, farm and system of housing on longevity and production traits were investigated. Longevity traits were studied using total lifetime (TL), length of productive life (LPL) and number of lactations (NL) while production was researched using lifetime milk yield (LMY). Data of 2037 Holstein dairy cows were provided by the main breeding organizations at the Faculty of Agriculture, University of Novi Sad. The average values and variability of examined traits as well as the effect of factors on longevity and production traits were investigated using fixed effect model by general linear model (GLM) procedure in software package Statistica 13. Results showed highly significant effect of the AFC, calving season and farm, on all studied longevity traits (P less than 0.01), while non- significant effect was expressed on lifetime milk yield (P greater than 0.05). The mean of AFC, TL, LPL, NL and LMY for Holstein cows were 27.3, 67.5, 40.2 months, 2.45 and 18798.0 kg, respectively. The maximum values of LPL, NL and LMY were noticed for cows with age at first calving before 23 months of age. The LPL ranged from 47.88 (AFC less than 23 m) to 35.84 m (AFC>29 m) and declined progressively when the AFC is increased, particularly in cows calving at more than 29 m.

This study assessed the effects of Senecio scandens Buch. Ham.extract on reproductive spectrum in female mice using a three phase reproductive assessment method. Sperm abnormality rate was used to evaluate effect on genetic reproductive toxicity. Senecio scandens extract was relatively non-toxic at low doses in all phases of reproduction in female mice. However, it showed a dose-response effect on sperm abnormality rate, and at high doses has the potential to induce genetic reproductive toxicity in male mice. It is suggested that the well-understood pharmacological benefits of S. scandens extract as an herbal medicine far outweigh the minimal reproductive toxicity effects observed in this study.

Bull fertility is an important factor for genetic improvement; therefore prediction of fertility an early age of the bulls by using genetic markers is a goal for livestock breeding. Zinc finger protein280BY linked gene is predominantly expressed in testis and has a major role in spermatogenesis. An investigation was carried out to detect the genetic variants in the male specific region (MSY) of ZNF280BY gene and their association with semen quality traits in Murrah buffaloes. Polymerase Chain Reaction-Single Strand Conformation Polymorphism technique (PCR-SSCP) and DNA sequencing methods revealed three different SSCP band patterns (AA, BB, CC); one transition (C10375T) and an indel (insertion of T at 10460-10461). The associations of the genetic variants with semen volume, sperm concentration, Hypo Osmotic Swelling Test (HOST) in fresh and frozen semen were observed. AA and CC genotype bulls had high volume (P£0.05) of semen per ejaculation than BB genotype bulls. BB genotype bulls had high sperm concentration (106/mL) per ejaculate in comparison to AA and CC genotype bulls (P£0.05). AA and BB genotype bulls had a higher per cent of HOST (P£0.05) reacted sperms of fresh semen and per cent acrosomal integrity of frozen semen in comparison to CC genotype bulls. The observed association between SSCP variants in MSY region of ZNF280BY gene with semen quality parameters indicated the possibilities of using ZNF280BY as a candidate gene for identification of markers for semen quality traits in Murrah buffaloes.

Cowpea is an important food crop with high nutritional and socio-economical values in South Sudan. However, the lack of improved varieties is one of the main production constraints. This study was undertaken to assess the yield stability performance of improved cowpea genotypes across six environments in South Sudan in 2014 and 2015. Nine genotypes were evaluated in a randomized complete block design with three replications. Genotype and genotype x environment biplot analysis method was used to determine yield stability. Highly significant (p less than 0.001) genotype x environment interaction effect was detected for seed yield. IT90K-277-2 had the highest while ACC004 had the lowest grain yield. Palotaka was as highly discriminating and repeatable environment compare to the other testing sites. IT07K-211-1-8 and Mading Bor II were the most responsive genotypes, while IT90K-277-2 was the most stable high yielding genotype across the test environments and can be grown by farmers across the region.
Reducing Veterinary Waste: Surgical Site Infection Risk and the Ecological Impact of Woven and Disposable Drapes
Authors: Vasanthakumar Molly
Published: July 2019

PICO questionIn animals undergoing surgery, does the use of disposable synthetic drapes reduce the risk of surgical site infections when compared to reusable woven drapes?Clinical bottom lineCurrent literature on the risk of surgical site infection with disposable and reusable drapes in animals is limited. Three human studies were reviewed, one systematic review and two controlled trials. Both these study types generally provide high levels of evidence; however their individual limitations reduce the quality of their data. Overall the results were mixed, and due to the small number of reviewed papers and the fact that only one study specifically measured surgical site infection as the outcome, it is not possible to conclude that disposable drapes reduce the risk of surgical site infections (SSI) when compared to reusable drapes.The impact of the veterinary profession on the ecosystem is often ignored. When following the One Health concept, vets must consider the ecological impact of clinical decisions. Choosing reusable drapes for certain clean, elective procedures may be a way to reduce waste without compromising the health of patients.
