Features of hemostasis disorders in patients with CKD VD stage and their relationship with the course of the disease

Disorders in the hemostatic system leading to the development of thrombosis are one of the main complications in patients with chronic kidney disease (CKD) of stage VD who are on program hemodialysis. The development of thrombophilic syndrome as a process of intravascular coagulation is characterized by systemic activation of procoagulative mechanisms, which are not always compensated by internal natural anticoagulant systems. The determination of early predictors of possible thrombogenesis in the studied category of patients causes significant difficulties. The goal is to study the features of hemostatic system disorders in patients with CKD VD stage who are on programmed hemodialysis, and to assess their relationship with the characteristics of the course of the disease. In 88 patients with CKD of the VD stage who are on program hemodialysis (52 men and 36 women), the features of hemostasis disorders depending on the clinical characteristics of the patients were studied. The indicators of prethrombosis (soluble fibrin (sF), fibrinogen (Fg), functionally inactive forms of prothrombin (FIFP)), postthrombosis (D-dimer (D-d)) and anticoagulation (protein C (pC)) were determined depending on gender, hemodialysis experience, age, the presence of anemia, arterial hypertension (AH) and preserved residual renal function (RRF). Statistical processing of materials was carried out using methods of variation statistics using t-student criterion. It was found that violations in the hemostatic system are detected in almost all patients. At the same time, hyperfibrinogenemia, an increase in sF concentration, a deficiency of pC, less often an accumulation of FIFP and high levels of D-d are most often observed. These disorders of hemostasis are more often found in patients with absent RRF, a longer experience of hemodialysis, the presence of arterial hypertension and are less associated with gender, age of patients and are little dependent on the degree of anemia.
IMPACT OF ORGANIZATIONAL LIFE CYCLE STAGES ON QUALITY OF CORPORATE GOVERNANCE: EMPIRICAL EVIDENCE FROM PAKISTAN’S CORPORATE SECTOR

The purpose of this research study is to determine the influence of the different organizational life cycle stages in modeling the quality of corporate governance. The study employs data of 46 companies listed with the KSE 100 index and uses a governance prediction model to determine the nexus between the organizational life cycle and the quality of corporate governance. The longitudinal data on corporate governance may help to identify the changes within a firm over time. However, of this time series data has compelled us to use the variations in corporate governance between-firms at distinct life-cycle stages. The study finds that mature firms as being high in resources are better governed overall. Transparency, responsibility, and accountability are higher in growth firms, whereas discipline and independence improve as firms mature. The results of the study recommend that governance functions such as monitoring/control and resource/strategy are significant and relatable at different life-cycle stages.
Investigations on the control of fruit drop in alphonso mango

Field experiments were conducted during 1998-2002 for identification of pollinizer varieties, control of recurring flowering and control of fruit drop by use of mineral nutrients and growth regulators in Alphonso mango at the Regional Fruit Research Station, Vengurle, Sindhudurg. The investigations revealed that variety Kesar, Ratna and Goamankur were the best pollinizer varieties for Alphonso mango as substantiated by synchrony in flowering with Alphonso, better fruit set and acceptable fruit quality of pollinizer. Alphonso x Alphonso cross combination showed only 4% fruit retention whereas, Alphonso x Kesar, Alphonso x Ratna and Alphonso x Goamankur revealed 10-12% fruit retention. Therefore, plantation of 10 to 15% trees of Kesar, Ratna or Goamankur in Alphonso orchards as pollinizers was recommended. The recurring flowering emerging at the base of old flowering panicle causes heavy fruit drop from adjacent old ones. The foliar spray of GA 3 (50 ppm) at full bloom stage significantly reduced the recurring flowering in Alphonso mango. For control of flower/fruit drop in Alphonso mango, foliar spray of nutrients (urea, KNO 3 , micronutrient complex) and growth regulators (NAA, triacontanol) at different concentrations were tested separately and in combination. The three years data revealed that urea 2%, NAA 20 ppm and micronutrient mixture 50 ppm in combination produced significantly higher fruit yield followed by combined application of urea + triacontanol + micronutrient.
The effectiveness of social distancing in containing Covid-19

ABSTRACT A statistical measure of the containment of Covid-19 is proposed to describe seven possible outcomes ranging from the worst outcome of ‘beyond control’ and the best outcome of ‘under control with rapid progress towards zero infections’. This measure is used to examine the performance of 10 countries with emphasis on the role of government-imposed measures of social distancing (lockdown, etc.). The results show that social distancing is effective, even though it is difficult to separate the effect of government measures from that of social distancing triggered by personal initiatives. The experience of Sweden shows that social distancing as a personal initiative is inadequate for the purpose of containing the virus. The experience of Brazil shows that taking the virus lightly brings about serious consequences.
Covid-19 Airborne Transmission and Its Prevention: Waiting for Evidence or Applying the Precautionary Principle?

Besides the predominant ways of transmission of SARS-CoV-2 (namely, contacts and large droplets) the airborne one is increasingly taken into consideration as a result of latest research findings. Nevertheless, this possibility has been already suggested by previous studies on other coronaviruses including SARS-CoV and MERS-CoV. To describe the state of the art of coronaviruses and airborne transmission, a systematic review was carried out using the PRISMA methodology. Overall, 64 papers were selected and classified into three main groups: laboratory experiments (12 papers), air monitoring (22) and epidemiological and airflow model studies (30). The airborne transmission of SARS-CoV-2 is suggested by the studies of the three groups, but none has yet obtained complete evidence. The sampling and detection methods have not been validated, therefore monitoring results are affected by a possible underestimation. Then, epidemiological investigations only hypothesize the airborne transmission as a possible explanation for some illness cases, but without estimating its attributable risk. Nevertheless, while waiting for more evidence, it is urgent to base advice on preventive measures, such as the use of masks, safe distancing and air ventilation, on the precautionary principle.
Genetic Variability, Heritability and Genetic Advance in Brinjal (Solanum melongena L.)

A field investigation was carried out with 180 genotypes of brinjal to study the genetic variability, heritability and genetic advance of thirteen different characters. Highly significant differences were observed among all the genotypes and characters except days to last picking under study indicating the presence of sufficient amount of variability in all the characters. PCV estimates were higher than their corresponding GCV for all characters studied. GCV was found low for all the characters whereas, PCV was moderate for fruit yield per plant (15.69%) followed by number of fruits per plant (15.43%). High heritability was noticed for fruit length (86.62%), plant height (76.73%), plant spread – EW (72.99%), number of branches per plant (72.12%) and total soluble solid (63.38%). Expected genetic advance was observed to be low for all the characters. Therefore, studied characters may be included in assortment criterion for improvement in fruit yield per plant in brinjal.
Prospective study of relationship between deep vein thrombosis and homocysteine related group B vitamins

Introduction: Hyper homocysteinemia has been considered as a potential risk factor for deep venous thrombosis (DVT) but it is still controversy. This study was aimed to assess the prevalence of hyper homocysteinemia in our population with DVT. Our second objective was to document the prevalence of folate, Vitamin B6, and Vitamin B12 level in this patient population. Results: Mean serum homocysteine levels among DVT patients was 15.12±5.47 μmol/L. Most of the patients of DVT were from 41-60 years of age group with mean age being 50.11±13.66 years. Of all the patients, 15 patients had homocysteine level above the 15 µmol/L, 22 had folic acid level below 3 ng/ml, 14 had vitamin B12 level below 150 pmol/L, and 3 had vitamin B6 level below 30 nmol/L. In the hyper homocysteinemic group, eleven patients had low folic acid level, ten had low vitamin B12 level and two had low vitamin B6 level.Conclusions: Hyper homocysteinemia and related Vitamin B group deficiency are risk factors for Deep vein thrombosis. Hyper homocysteinemia and risk of DVT, this correlation is high among older age group and female patients.
Seed biometry: another functional trait in caatinga

Seed biometrics is an excellent tool for understanding environmental filters, species potential and dispersal, successional stages of communities and the dynamics used by seeds to germinate, establish and develop, thus constituting a functional trait of the species. We aim to understand the relationship between aspects of seed biometrics and other phenological traits, in order to infer contributions about functional strategies in Caatinga. Between September 2017 and January 2019, 10 individuals of Cenostigma pyramidale (Tul.) LP Queiroz, Commiphora lepthophloeos (Mart.) JB Gillett, Jatropha mollissima (Pohl.) Baill. , Monteverdia rigida (Mart.) Biral. Pseudobombax marginatum (A.ST.-Hil) A. Robyns, Zizyphus joazeiro Mart. were monitored for the selection of three seed collection matrices. From each matrix 100 seeds were collected, which after screening resulted in 35 intact seeds that were used to measure length, width, thickness and volume. Caatinga seeds are generally small, as a result of the environmental stresses of the Brazilian semiarid. The analyzed variables separated three groups in the PCA. We noticed that these groups evidenced the successional stages in the Caatinga. One group included M. rigida and P. marginatum, which are late secondary. C. pyramidale and C. lepthophloeos formed another group coincident with intermediate successional stages. J. mollissima and Z. joazeiro formed a group of pioneer species in anthropized environments. Another finding was that the area was in secondary succession. The pioneer species presented the largest seeds and this characteristic is associated with the need for nutrient reserve that allows the embryo to germinate and last for a longer period without the need for exogenous nutrients, an essential condition for the Caatinga. With the advancement of ecological succession and the establishment of a more consolidated plant community, competition for resources, the frequent dispersion vector type and the nature of the environmental stresses present, the seeds may be smaller.
The Effect of Using Padlet as a Vocabulary Knowledge Enhancement Application on Saudi EFL Female Learners, and their Attitudes toward its Value in Learning

This study aimed to investigate the effects of using the digital learning tool Padlet to teach English vocabulary to Saudi females learning English as a Foreign Language (EFL) within the context of Communicative Language Teaching (CLT). Specifically, it examined the attitudes and thoughts of these females toward the application and the effectiveness of using it as a learning platform. The study was set out to answer two questions; the first questions is “How effective is the application Padlet with regard to using a CLT approach to teach English vocabulary skills to Saudi female EFL learners? ” while the second one is “What are users’ attitudes toward the online learning platform Padlet? ”. The experiment was conducted for two weeks using Padlet. The population size was 50 Saudi females who were level-eight students at the English Language and Translation Department of Al-Imam Muhammad Ibn Saud Islamic University in Riyadh, Saudi Arabia. After inclusion criteria (i.e., the results of an English language placement test) were applied, 30 students were selected for the study; this was done to ensure that the group was homogenous with regard to the level of English skill. The remaining participants then took a pretest; subsequently, the researcher and subjects engaged in seven instruction sessions using Padlet, during which the researcher followed a Communicative Language Teaching approach to presenting English vocabulary. After the experiment was concluded, the participants were given a posttest identical to the pretest in order to assess their knowledge and compare their vocabularies before and after the instructions were provided. In addition, the participants responded to an online survey designed to measure their attitudes toward Padlet. The participants’ scores and mean scores were calculated using the Statistical Package for Social Science (SPSS); specifically, a one-sample t-test and a paired sample t-test were conducted. The findings revealed that the vocabulary instructions given using Padlet were effective at improving the English lexical knowledge of learners. The survey also revealed that the learners’ attitudes toward the tool were positive. Finally, the results indicated that the implementation of Communicative Language Teaching through Padlet was crucial to developing the participants’ English vocabulary skills.
Extreme reduction of on-resistance in vertical GaN p–n diodes by low dislocation density and high carrier concentration GaN wafers fabricated using oxide vapor phase epitaxy method

Low dislocation density and low-resistance GaN wafers are in high demand for improving the performance of vertical GaN power devices. Recently, GaN wafers with the dislocation density of 8.8 × 104 cm−2 and the resistivity of 7.8 × 10−4 Ω cm, were fabricated using oxide vapor phase epitaxy (OVPE). In this study, GaN p–n diodes on GaN wafers prepared by the OVPE method were evaluated for verifying their suitability as vertical GaN power devices. An extremely low-differential specific on-resistance of 0.08 mΩ cm2 and a high breakdown voltage of 1.8 kV were obtained from forward and reverse I–V measurements.
The Use of Edutainment in Promoting Higher Order Thinking Skills in ESL Writing among Malaysian University Students

The aim of this article is to investigate the perceptions of university students on the use of edutainment in promoting Higher Order Thinking Skills (HOTS) in English as a second language (ESL) writing. 20 diploma students from Malaysia University of Science & Technology (MUST) participated in this study. This study adopts quantitative research design where a set of questionnaires was distributed to the students. Before answering the questionnaire, the students went through a treatment using edutainment. They had to play an online game downloaded from Play Store. They spent 13 weeks playing the game. At the end of the treatment, they had to sit for the post test. Then they were asked to complete the questionnaire. This study is in bringing positive impact to the society starting from the ministry to the students regarding the importance of the edutainment implementation in classroom teaching. The findings reveal that the students perceived that Edutainment has affected the stimulation of higher order thinking skills in their writing. This suggests that edutainment should be incorporated in the teaching and learning English.
Computing the Growth of Small Cracks in the Assist Round Robin Helicopter Challenge

Sustainment issues associated with military helicopters have drawn attention to the growth of small cracks under a helicopter flight load spectrum. One particular issue is how to simplify (reduce) a measured spectrum to reduce the time and complexity of full-scale helicopter fatigue tests. Given the costs and the time scales associated with performing tests, a means of computationally assessing the effect of a reduced spectrum is desirable. Unfortunately, whilst there have been a number of studies into how to perform a damage tolerant assessment of helicopter structural parts there is currently no equivalent study into how to perform the durability analysis needed to determine the economic life of a helicopter component. To this end, the present paper describes a computational study into small crack growth in AA7075-T7351 under several (reduced) helicopter flight load spectra. This study reveals that the Hartman-Schijve (HS) variant of the NASGRO crack growth equation can reasonably accurately compute the growth of small naturally occurring cracks in AA7075-T7351 under several simplified variants of a measured Black Hawk flight load spectra.
Experimental study of surface roughness, dimensional accuracy and time of fabrication of parts produced by fused deposition modelling

Purpose This paper aims to focus on an experimental study of surface roughness, dimensional accuracy and time of fabrication of parts produced by fused deposition modelling (FDM) technique of additive manufacturing. The fabricated parts of acrylonitrile butadiene styrene (ABS) material have pyramidal and conical features. Influence of five process parameters of FDM, namely, layer thickness, wall print speed, build orientation, wall thickness and extrusion temperature is studied on response characteristics. Furthermore, regression models for responses are developed and significant process parameters are optimized. Design/methodology/approach Comprehensive experimental study is performed using response surface methodology. Analysis of variance is used to investigate the influence of process parameters on surface roughness, dimensional accuracy and time of fabrication in both outer pyramidal and inner conical regions of part. Furthermore, a multi-response optimization using desirability function is performed to minimize surface roughness, improve dimensional accuracy and minimize time of fabrication of parts. Findings It is found that layer thickness and build orientation are significant process parameters for surface roughness of parts. Surface roughness increases with increase in layer thickness, while it decreases initially and then increases with increase in build orientation. Layer thickness, wall print speed and build orientation are significant process parameters for dimensional accuracy of FDM parts. For the time of fabrication, layer thickness and build orientation are found as significant process parameters. Based on the analysis, statistical non-linear quadratic models are developed to predict surface roughness, dimensional accuracy and time of fabrication. Optimization of process parameters is also performed using desirability function. Research limitations/implications The present study is restricted to the parts of ABS material with pyramidal and conical features only fabricated on FDM machine with delta configuration. Originality/value From the critical review of literature it is found that some researchers have made to study the influence of few process parameters on surface roughness, dimensional accuracy and time of fabrication of simple geometrical parts. Also, regression models and optimization of process parameters has been performed for simple parts. The present work is focussed on studying all these aspects in complicated geometrical parts with pyramidal and conical features.

Developmental pathways of preadolescents' intrinsic and extrinsic values: The role of basic psychological needs satisfaction

The purpose of the study was to examine longitudinally how intrinsic and extrinsic values develop during preadolescence within a mother-child context by comparing three different developmental pathways—direct value transmission, indirect value transmission, and value origination. Two hundred and thirty-three Korean mother—child dyads of late elementary students (Mage = 11.4 years; 55% girls) participated in a year-long online questionnaire survey. A longitudinal structural equation modelling analysis revealed two contrasting developmental pathways for intrinsic and extrinsic values in preadolescents. Intrinsic values developed via value origination, while extrinsic values developed via direct transmission. In other words, intrinsic values originated from the child's own inner psychological experiences and developed in accordance with changes in psychological needs satisfaction, whereas extrinsic values were transmitted from mothers in accordance with the degree to which they endorsed extrinsic values.
Implementing TED Talks as Authentic Videos to Improve Taiwanese Students’ Listening Comprehension in English Language Learning

This research paper explores implementing authentic video materials in EFL listening classrooms. Videos have been used as one of the English listening learning resources; however, without effective learning supports, EFL students are likely to encounter difficulties in comprehending the content on videos and then demotivate learning English. This study aimed to incorporate authentic online videos into students' English listening activities in college-level English classrooms in a private comprehensive university in southern Taiwan. Based on the research background and rationale, there were three main questions :(1) Is there a significant difference among students with different majors on the perceptions of the effectiveness of the listening activities on watching Technology Entertainment and Design Talks videos? (2) Is there a significant difference among students with the content familiarity in their learning with TED Talks videos? (3) What are the students' perceptions of practicing English listening with TED Talks videos? This research was conducted in a one-semester project to uncover 82 EFL learners’ self-reports of learning their online video materials. TED Talks videos and listening activities were utilized in this learning environment. A questionnaire was administered and consisted of demographic information, Likert scale questions, and interviews. The results showed that most students considered that they improved their listening comprehension after learning the TED talks video. Students recalled their background knowledge and analyzed content in the TED Talks.
