Endophytic bacterial communities colonizing the medicinal plant Calotropis procera: as resources of hydrolases

Calotropis procera (Aiton) W.T. Aiton is a shrub belongs to family Asclepiadaceae which known by its medicinal properties. It is a widely growing plant distributed in tropical and sub-tropical Africa, and America. This study is the first report which highlights the diversity of bacterial endophytes from C. procera as sources of numerous hydrolytic exo-enzymes. Endophytic bacteria were isolated from all plant parts such as; roots, stems, leaves, flowers, fruits and latex. Bacillus was the prevalent genus. At the species level, the bacterial diversity was high. Eight representative species were isolated including; Citricoccus alkalitolerans (Cps2) (NR025771), Bacillus cereus (Cps1) (NR074540), B. pumilus (Cps3) (NR112637), B. firmus (Cpl1) (NR025842), B. niabensis (Cpl3) (NR043334), B. subtilis (Cpl4) (NR113265), B. amyloliquefaciens (Cpl10) (NR041455) and B. subtilis subsp. spizizenii (Cpl13) (NR112686). Results of the current study emphasized that C. procera plant hosts diverse endophytic bacteria, which are potential producers of several economically important hydrolytic enzymes i.e., amylase, protease, cellulase, lipase and L-asparaginase. The aims of the current study were to identify the endophytic bacteria associated with the different organs of the medicinal plant C. procera, and to evaluate their potentialities to produce diverse extracellular hydrolytic enzymes.
Anoxia at Birth Induces Behaviorally-Relevant Changes in alpha2-Noradrenergic Receptor Binding in the Adult Rat

Evidence suggests that Caesarean section birth in the rat, with or without an additional period of anoxia, results in long-term changes in brain catecholamine levels as well as reactivity to stress. The purpose of the present investigation was to determine whether Caesarean birth plus anoxia alters (alpha)2-noradrenergic receptor binding and sensitivity to the (alpha)2 receptor agonist, clonidine, in the Porsolt forced swim test. Sprague Dawley rat dams were decapitated and the uteruses were removed by Caesarean section. Pups were then delivered either immediately (Caesarean Only group), or were immersed in a saline bath for approximately 15 minutes (Caesarean plus Anoxia group) before delivery of the pups. A third group of animals born vaginally served as controls (Vaginally-born group). Four to five months postnatally, the expression of (alpha)2 receptors was measured by receptor autoradiography using [3H]-Rauwolscine binding. Receptor binding was increased in the area of the ventral hypothalamus and decreased in the CA1 region of the hippocampus in animals subjected to Caesarean plus Anoxia at birth. These animals also displayed a subsensitive response to the immobilizing effects of clonidine (100 micrograms/kg, i.p.) in the Porsolt forced swim test. Specifically, these data show that Caesarean birth produces long-term changes in (alpha)2 receptor density and that, in animals subjected to Caesarean plus anoxia, these changes are reflected in a behavioral subsensitivity to the (alpha)2 agonist, clonidine. The findings reported here provide further experimental support for the hypothesis that birth complications may contribute to the pathophysiology of disorders such as schizophrenia that involve central catecholamine dysfunction.
Nexus between intellectual capital and profitability with interaction effects: panel data evidence from the Indian healthcare industry

PurposeThis study seeks to understand the nexus between intellectual capital and profitability of healthcare firms in India with interaction effects.Design/methodology/approachRelevant data were extracted from the Centre for Monitoring Indian Economy (CMIE)'s Prowess database for a period of ten years 2009–2018 for a sample of 84 selected firms from the healthcare industry. This study uses value added intellectual coefficient (VAIC) and modified value added intellectual coefficient (MVAIC) as a measure of intellectual capital. Further, the study employs panel regression techniques to explore the relationship between intellectual capital and profitability.FindingsThe empirical findings reveal that the intellectual capital coefficient of healthcare firms in India averages 2.7757. It is also observed that a majority of the healthcare firms' intellectual capital coefficient is below the industry average. From the regression analysis, it is evident that the intellectual capital coefficient is positively related to the profitability of healthcare firms in India. As far as the components of intellectual capital coefficient are concerned, the capital employed coefficient (CEC) is the only component driving the profitability of healthcare firms in India. A further introduction of interaction terms improves model explainability and moderates the impact of the predictor variable on the response variable. Furthermore, it is observed that the intellectual capital coefficient of the healthcare industry is immune to changes in political regimes in India.Practical implicationsThe findings reveal that intellectual capital is an important driver of corporate performance, thus healthcare firms in developing economies like India need to enhance their intellectual potential. Therefore, corporates and governments in developing economies should stimulate investments in developing intellectual capital for enhanced corporate performance and economic growth. Thus, this study might be used as a reference by policymakers while drafting the future policy for the development of intellectual capital in general and healthcare sector specifically.Originality/valueThis is among the first few studies to explore such an empirical relationship for healthcare firms in India and among the few studies of this kind across the globe. It also makes novel contributions in considering interaction variables and seeking the consistency of results across different political regimes. However, the study examines one nation and one industry; thus, the generalisation of findings requires caution.
Kinetics and mechanism of metallocene‐catalyzed olefin polymerization: Comparison of ethylene, propylene homopolymerizations, and their copolymerization

A series of ethylene, propylene homopolymerizations, and ethylene/propylene copolymerization catalyzed with rac-Et(Ind)2ZrCl2/modified methylaluminoxane (MMAO) were conducted under the same conditions for different duration ranging from 2.5 to 30 min, and quenched with 2-thiophenecarbonyl chloride to label a 2-thiophenecarbonyl on each propagation chain end. The change of active center ratio ([C*]/[Zr]) with polymerization time in each polymerization system was determined. Changes of polymerization rate, molecular weight, isotacticity (for propylene homopolymerization) and copolymer composition with time were also studied. [C*]/[Zr] strongly depended on type of monomer, with the propylene homopolymerization system presented much lower [C*]/[Zr] (ca. 25%) than the ethylene homopolymerization and ethylene–propylene copolymerization systems. In the copolymerization system, [C*]/[Zr] increased continuously in the reaction process until a maximum value of 98.7% was reached, which was much higher than the maximum [C*]/[Zr] of ethylene homopolymerization (ca. 70%). The chain propagation rate constant (kp) of propylene polymerization is very close to that of ethylene polymerization, but the propylene insertion rate constant is much smaller than the ethylene insertion rate constant in the copolymerization system, meaning that the active centers in the homopolymerization system are different from those in the copolymerization system. Ethylene insertion rate constant in the copolymerization system was much higher than that in the ethylene homopolymerization in the first 10 min of reaction. A mechanistic model was proposed to explain the observed activation of ethylene polymerization by propylene addition. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Vertical Integration of Healthcare Providers Increases Self-Referrals and Can Reduce Downstream Competition: The Case of Hospital-Owned Skilled Nursing Facilities

The landscape of the U.S. healthcare industry is changing dramatically as healthcare providers expand both within and across markets. While federal antitrust agencies have mounted several challenges to same-market combinations, they have not challenged any non-horizontal affiliations – including vertical integration of providers along the value chain of production. The Clayton Act prohibits combinations that “substantially lessen” competition; few empirical studies have focused on whether this is the source of harm from vertical combinations. We examine whether hospitals that are vertically integrated with skilled nursing facilities (SNFs) lessen competition among SNFs by foreclosing rival SNFs from access to the most lucrative referrals. Exploiting a plausibly exogenous shock to Medicare reimbursement for SNFs, we find that a 1 percent increase in a patient’s expected profitability to a SNF increases the probability that a hospital self-refers that patient (i.e., to a co-owned SNF) by 2.5 percent. We find no evidence that increased self-referrals improve patient outcomes or change post-discharge Medicare spending. Additional analyses show that when integrated SNFs are divested by their parent hospitals, independent rivals are less likely to exit. Together, the results suggest vertical integration in this setting may reduce downstream competition without offsetting benefits to patients or payers.
Individual and Combined Toxic Effects of Herbicides on Growth Parameters and Fecundity of Eisenia fetida

Earthworms contribute a lot to the soil biodiversity; they are the basic driver of abiotic and biotic soil properties. Their feeding, burrowing and casting activities influences the structure of soil, regulation of water, bioremediation of toxins, organic matter distribution and soil structure. They can modify soil porosity, water infiltration, soil aeration and fertility. So earthworms are also known as ecosystem engineers in the terrestrial soils due to their contribution in pedogenesis. Indiscriminate use of pesticides, herbicides, inorganic fertilizers and other metal mixtures at large scale to enhance agriculture production have had negative effects on soil fauna, especially earthworms and they are being killed as non-targeted organisms. Non judicious use of agrochemicals may induce damage at genetic level, disruption in enzyme activities, low survival rate, reduced reproduction and growth rate etc which ultimately results in decreased total earthworm biomass.

Impact of fertilizer types on the nutritive quality of two tropical grass species harvested at different stages of growth during wet season

The use of inorganic fertilizers has been reported to have improved pasture productivity, however it has also attributed to soil toxicity, environmental pollution, mineral imbalance, and health hazards among many adverse effects. This made the adoption of organic fertilizers became best alternative to correct nutrients deficiencies in the soil due to their environmental friendly nature and less cost effectiveness. To investigate the comparative advantages of these two types of fertilizer, an experiment was conducted to evaluate the influence of fertilizer types on the nutritive quality of Panicum maximum var. Ntchisi and Andropogon tectorum harvested at 6 and 8 weeks during the wet season. The study was a factorial experiment (4 x 2 x 2), arranged in a split-split-plot design with three replicates. There were 16 treatments to include; fertilizer types (NPK, Aleshinloye organo-mineral fertilizer, poultry manure and control (no fertilizer)), grass species (Panicum maximum var. Ntchisi and Andropogon tectorum) and age at harvest (6 and 8 weeks). Fertilizer treatments were allotted to the main plots while grass species were allotted to sub-plots and again harvest age was allotted to sub-subplots. Sub-samples taken from harvested forage materials were oven dried, properly milled and analysed in the laboratory to determine proximate composition [crude protein (CP%), ash, ether extract (EE%)], fibre fractions [acid detergent fibre (ADF%), neutral detergent fibre (NDF%), acid detergent lignin (ADL%), Cellulose, and Hemicelluloses) and in vitro gas production. Fertilizer types significantly (P<0.0.5) affected ADF, hemicellulose, cellulose and methane (CH4). The grasses fertilized with NPK had the highest value (9.00mL) for CH4. Poultry manure (PM) fertilized grasses recorded the highest value for in vitro dry matter digestibility (IVDMD) (89.38%). Andropogon tectorum fertilized with PM harvested at 6 weeks recorded the highest value for IVDMD (93.00%) and the same grass fertilized with NPK, harvested at 6 weeks recorded the highest values (0.37 mL and 4.70%) for short chain fatty acid and metabolizable energy, respectively. Therefore, this study established that fertilizer applications had an influence on fibre fraction, methane and post-incubation parameters of the grasses investigated.
Indonesian EFL Teachers’ Challenges in Assessing Students’ Higher-Order Thinking Skills (HOTS)

Higher-Order Thinking Skills (HOTS) must be implemented in every subject, including the English Language in the 2013 curriculum by the Ministry of Education and Culture in Indonesia. HOTS is the upper three levels of cognitive learning (analyzing, evaluating, and creating) coined by Bloom, known as Bloom’s Taxonomy. The concepts of HOTS are too vague to guide the teacher in teaching and assessing HOTS because the construct of HOTS is abstract and multi-nature. HOTS assessment has also been unbounded because every teacher has their perceptions in assessing different students. Therefore, this study investigates EFL teachers' strategies in assessing students’ HOTS and its challenges. The research used a qualitative method, particularly descriptive study—the data about how teachers assess students’ HOTS and its challenges collected through questionnaires and an interview. The research participants were EFL teachers of public schools in Indonesia. The findings indicated that from 22 EFL teachers, the strategies used mostly are summative assessment and authentic assessment in assessing students’ HOTS. Besides, the teachers never made HOTS questions because of a lack of understanding of HOTS assessment. This implied that teachers faced challenges in assessing students’ HOTS. The challenges are divided into two aspects; teachers’ understanding of the concept of HOTS assessment and students’ aspects.
Structural Assessment and Scantlings of Traditional Small Crafts

The scantlings of traditional wooden crafts often originate from the extensive experience of designers and boatbuilders. With the contemporary regain of interest for historical replicas and timber construction, and the ever-critical necessity to minimise displacement, a compromise between the original scantlings and modern structural assessment must be struck. The latter heavily relies on rules-based design, driven by formal regulations, though a number of empirical methods also exist. Consequently, to assess the comparative structural requirements between traditional small crafts, empirical methods and regulatory requirements, case studies will be undertaken on small crafts. Ultimately, the results showcase the differences between original specifications, the recommendation of simplified methods, and modern rules, with the latter allowing for weight savings.
Counsellors as a client: group counselling

ABSTRACT The purpose of this study is to investigate the effect of group counselling on the awareness of the participants about their feelings, their ability to recognise emotional expressions and their cognitive emotion regulation strategies. In the study, experimental pretest-posttest and follow-up testing with control group design was used and a total of 24 subjects, 12 in the experimental group and 12 in the control group, participated in the study. As a result of the study, significant differences were found in the TAS-20; whereas there was no significant difference in JACFEE, and Cognitive Emotion Regulation Questionnaire results. The follow-up test administered 8 weeks later showed that the scores that participants achieved from TAS-20 were maintained after the experiment.
Standard Heterosis for Seed and Oil Yield in Sunflower (Helianthus annuus L.)

This article is based on a study that was carried out to identify the best hybrid combinations giving high degree of useful heterosis for economic traits such as seed and oil yield in sunflower under high saline soil in coastal saline belts of West Bengal. The present study was carried out at Nimpith (West Bengal) in 2017-18 and 2018-19 with the specific objectives of identifying the standard heterotic cross combinations of sunflower hybrids and identifying the superior sunflower hybrids suitable for growing in rabi season in West Bengal’s agro-climatic conditions. A set of sunflower hybrids along with the three national checks, LSFH-171, KBSH-53 and DRSH-1, were evaluated in a randomized block design. The degree of heterosis varied for important useful characters among the different crosses. Presence of high heterosis in certain crosses and low in others suggested that the nature of gene action varied with genetic architecture of the parents. From the study, it may be concluded that the sunflower hybrids viz. CMS 519A X TSG-255, CMS 148A X EC-201868 and CMS 207A X R-272 may be promoted for AICRP multilocation trial or coordinated trial to evaluate their performance in Indian subcontinent. It is because of their superior traits for oil yield over the best national check sunflower hybrids in given environments.
Quantum Superpositions of Causal Structures

This presentation provides a non-technical overview of the notion of quantum superposition of causal structures, of its applications, and of its proposed physical realizations. The conceptual underpinning for these investigations is a view of quantum theory as a new kind of probability theory. At the axiomatic level, the principles of this new kind of probability theory suggest new causal relations that have no analogue in the classical world. These new causal relations are a potential resource for new technologies, including computation and communication technology.
Mechanical behaviour of bio-inspired brittle-matrix nanocomposites under different strain rates using molecular dynamics

We study the generic mechanical behaviour of ceramic–ceramic nanocomposites inspired from biological materials. The nanocomposite models considered in our study are the regularly and stairwise staggered arrangements of stiff brittle platelets embedded in compliant brittle matrix. Molecular dynamics simulations are carried out to investigate the effect of strain rate on these nanocomposites. The variation in stress–strain behaviour and mechanical properties are analysed. The evolution of deformation processes is also investigated. Our results show the existence of different strain rate regimes separated by critical strain rate. Deformation mechanisms such as matrix cracking, crack bridging, interfacial debonding and hence platelet pullout are observed at lower strain rates. Amorphous deformation and direct debonding without matrix cracking are observed at higher strain rates.
A study on the influence of poultry feed on the size, weight and protein content of egg

The egg of domestic fowl has been an important constituent of the cuisine of people around the world. The present study was carried out with the objective to analyse the influence of selected poultry feed on the size, weight and protein content of egg by feeding the hens with four different types of feed. Hens of the laying Gramasree variety were used in this experiments. Egg size, weight and the protein content was recorded as per standard procedures. Egg production significantly reduced in hen fed with cooked rice alone. When considering egg size and weight, domestic fowl fed with wheat, soya and groundnut had greater size. However, there has not been much variation in the protein content of all the eggs produced by the four hens in the present study. The study provides a baseline indication that the quality, size and weight of the egg are greatly influenced by their feed. Abstract
The Motivations of Learning English for Specific Purposes (ESP) Courses: A Study of English for Nursing Purposes

English language learning is not uncommon for many university students and programmes, particularly in the fields of nursing education. Pre-service nursing students are required to take certain courses of English language courses in order to meet the educational requirement in many universities in South Korea. However, there is no regulation about what types of English courses should be offered. In this study, based on the information (i.e. inductive surveys, interview sessions, and focus group activities) from 64 currently enrolled nursing students, the researcher sought to understand two research questions, which were, After the completion of both English for Specific Purposes (ESP) (i.e. English for Nursing Purposes) courses and English for General Purposes (EGP), which course would you prefer? Why; and how would the English for Specific Purposes (ESP) (i.e. English for Nursing Purposes) courses meet your expectations as nursing students at the university-level? The results indicated that nursing students tend to select the English for Specific Purposes (ESP) courses for their English language development because the materials were designed to meet their occupational needs after university graduation (i.e. in the health facilities). The outcomes of this study provided a blueprint for school leaders and department heads to reform and polish their nursing curriculum and plan in order to answer the feedback of the students and pre-service nursing professionals.
