Maximum Entropy Niche Modelling to Estimate the Potential Distribution of Phytophthora megakarya (Brasier & M. J. Griffin) in Tropical Regions

Background: Phytophthora megakarya is an invasive pathogen endemic to Central and West Africa. This species causes the most devastating form of black pod disease. Despite the deleterious impacts of this disease on cocoa production, there is no information on the geographic distribution of P. megakarya. Aim: In this study, we investigated the potential geographic distribution of P. megakarya in cocoa-producing regions of the world using ecological niche modelling. Methods: Occurrence records of P. megakarya in Central and West Africa were compiled from published studies. We selected relevant climatic and edaphic predictor variables in the indigenous range of this species to generate 14 datasets of climate-only, soil-only, and a combination of both data types. For each dataset, we calibrated 100 candidate MaxEnt models using 20 regularisation multiplier values and five feature classes. The best model was selected from statistically significant candidates with an omission rate ≤ 5% and the lowest Akaike Information Criterion corrected for small sample sizes, and projected onto cocoa-producing regions in Southeast Asia, Central and South America. The risk of extrapolation in model transfer was measured using the mobility-oriented parity (MOP) metric. Results: We found an optimal goodness-of-fit and complexity for candidate models incorporating both climate and soil data. Predictions of the model with the best performance showed that nearly all of Central Africa, especially areas in Gabon, Equatorial Guinea, and southern Cameroon are at risk of black pod disease. In West Africa, suitable environments were observed along the Atlantic coast, from southern Nigeria to Gambia. Our analysis suggested that P. megakarya is capable of subsisting outside its native range, at least in terms of climatic and edaphic factors. Model projections identified likely suitable areas, especially in Brazil and Colombia, from southwestern Mexico down to Panama, and across the Caribbean islands in the Americas, and in Sri Lanka, Indonesia, Malaysia, and Papua New Guinea in Asia and adjacent areas Conclusion: The outcomes of this study would be useful for developing measures aimed at preventing the spread of this pathogen in the tropics.
Comparative study of weaning pigs' muscle proteins using two-dimensional electrophoresis

The proteostasis system of animals, including various types of protein modification during the growth stage, leads to an almost incomprehensible number of possible forms of protein, and each can regulate numerous functions. In the presented work, the composition of muscle tissue protein from different portions of piglets was studied to understand the main muscle protein formation. Comparative analysis of weaned piglets' main muscle protein from l. dorsi, biceps femoris, and brachiocephalicus were analyzed using two-dimensional electrophoresis. Changes in the staining intensity of protein fractions inherent in different muscles were revealed. As part of this work, candidate groups of pig muscle proteins have been selected. Eleven protein spots were revealed for the longest muscle of the back, and seven for the biceps; the muscles of the neck are characterized by indicators of low protein fraction volume. Among the proteins found, myosin light chains, phosphoglycerate mutase, troponins, and adenylate kinase is most likely present. The obtained results of protein identification in muscle tissues, obtained during the intensive growth period, will allow a more detailed understanding of protein regulation, function, and interactions in complex biological systems, which will subsequently be significantly important for biomonitoring health and predicting farm animals productivity.

Introduction : Evidence suggests that supported employment strategies improve the rates of employment for individuals with schizophrenia. The Model of Occupational Self-Efficacy (MOOSE) is such a strategy aimed at enhancing work skills and facilitating return to work (RTW). The aim of the current study was to explore the experiences of individuals with schizophrenia about the use of the MOOSE in enhancing work skills and facilitating RTW in the open labour market. Method : A qualitative research project with an interpretivist paradigm explored the experiences and perceptions of nine participants diagnosed with Schizophrenia. Two occupational therapists participated as key informants. Data were collected by means of semistructured interviews and analysed using inductive thematic analysis. Results : Barriers and facilitators to the use of the MOOSE were revealed. More importantly, the MOOSE enhanced the development of worker identities and contributed to the successful adaptation of worker roles in the RTW process of individuals with schizophrenia in the open labour market. Conclusion : The MOOSE is an effective supported employment strategy for persons with schizophrenia. Factors such as client-centred practice, the presence of social support, and ongoing therapeutic support contributed to the participants’ successful RTW experienceIntroduction: Evidence suggests that supported employment strategies improv e the rates of employment for individuals with schizophrenia. Key words : Schizophrenia, supported employment strategies, Model of Occupational Self-Efficacy, return to work, perception, experience
EFFECTIVE MINORITY CARRIER LIFETIME AND DISTRIBUTION OF STEADY-STATE EXCESS MINORITY CARRIERS IN MACROPOROUS SILICON

We have obtained a simple expression that determines the effective minority carrier lifetime in macroporous silicon with periodic arrangement of infinitely long macropores as a function of bulk lifetime, surface recombination velocity of minority carriers, pore radius and the distance between the centers of macropores. This expression can be applied also to macroporous silicon with randomly distributed pores by replacing the pore radius and the distance between the centers of macropores with their average values. The distribution of steady-state excess minority carriers in macroporous silicon is calculated for the analytical model proposed by us. The calculation is made for the case when both the outer surface of macroporous silicon and the bottom of pores are illuminated with light. We observed two peaks of the distribution of steady-state excess minority carriers in macroporous silicon near the surfaces illuminated with light of wavelength 0.95 m. At the same time, if macroporous silicon was illuminated with light with the wavelength of 1.05 μm, we observed only one maximum in the distribution function of the excess minority carriers, in spite of the fact that the pore bottom was also illuminated with light. It is shown that the distribution of excess minority carriers in macroporous silicon with through pores is similar to the distribution in single crystal silicon. But in this case, the effective lifetime of minority charge carriers in the effective medium of macroporous silicon, which includes silicon and the surface of pores, corresponds to the bulk minority-carrier lifetime in monocrystalline silicon.
Sentiment Analysis towards Hotel Reviews

The used of social media analytic towards the information in social media could bring a significant impact toward the hotel business thus making it easier to gain such insight and analysis. A preliminary study showed that the hoteliers in Malaysia are unaware on the sentiment analysis computation in analyzing the customer review through TripAdvisor despite having the website to promote their hotel. This study aims to provide another addition of sentiment analysis study especially on hotel reviews dataset gain from TripAdvisor. The process start by scrapping the reviews from The Majestic Hotel in TripAdvisor. The dataset then undergoes a pre-processing stage using Valence Aware Dictionary for Sentiment Reasoning to identify the sentiment in the text reviews. The text reviews are converted into vector form and fed into machine learning classifier. Three type of machine learning classifier was chosen to classify the review that are Naïve Bayes, Support Vector Machine and Maximum Entropy. The classifiers are then evaluated using three measurement from the accuracy, precision and recall value perspectives in order to find the best classifier. Based on this study, Maximum Entropy gained the highest value compared to the other two classifier.
Antioxidant activity, total phenolic and flavonoid content of selected medicinal plants from Gorkha district, Nepal

Objective: To determine the antioxidant activity, total phenolic and flavonoid content of the methanolic extracts of Fritillaria cirrhosa, Rosa sericea, Neopicrorhiza scrophulariflora and Juniperus squamata. Methods: Antioxidant ability of the extracts was evaluated using 2, 2 diphenyl-1-picrylhydrazil (DPPH) as the source of free radical and butylated hydroxyanisole and vitamin C as reference compounds. Total phenolic content of the sample was estimated by the FolinCiocalteu method and total flavonoid content by the aluminium chloride method. Results: The extracts of J. squamata contained highest phenolic content whereas R. sericea contained highest amount of flavonoids. F. cirrhosa has negligible amount of total phenolic and flavonoids. Antioxidant activity, as determined by DPPH assay revealed that J. squamata and R. sericea had stronger activity. Conclusion: J. squamata and R. sericea possess higher phenolic and flavonoid content and strong antioxidant activity and could be useful as natural antioxidants.
Quantum model of naturally rotating Machian cosmology and galactic applications of current cosmic angular velocity

We would like to emphasize that, extraordinary physical concepts like Big bang, Inflation, Dark energy and Superluminal expansion demand super-normal efforts and need observational support. Observational data is raising day-by-day non-conformity and demanding changes in the original concepts. It is very interesting to note that James Peebles, the famous cosmologist and 2019 Nobel laureate strongly believes that Big bang concept is inappropriate in understanding the universe. It is better to understand and develop models of cosmology based on well supported physical concepts rather than extraordinary physical hypothesis. Unification point of view, quantum cosmology must be given a priority and one should make a note that, Spin is a basic property of quantum physics and rotation is a very common experience. In this context, with reference to life cycle of living creatures and independent of red-shift data, we have developed a quantum model of cosmology associated with Machian universe having Planck scale origin, total dark matter, light speed expansion, light speed rotation, equality of gravitational self energy density and thermal energy density, radially decreasing internal acceleration and radially increasing anisotropy. We are working on understanding and correlating observed redshift data in a unified approach. In this letter, we present various galactic applications of current cosmic angular velocity.
Improving Production Quality through Project Manage- ment: Lesson from Small-budget Films in China

China’s film industry is moving toward industrialization. Small-budget films, which account for the largest proportion of Chinese film production, face the most problems in production management, particularly quality loss. This study explores key factors that affect quality of film production so as to provide solutions that effectively reduce the loss of quality in the production stage. The analysis utilizes information from in-depth interviews with nine veterans in the industry and observations of six small-budget film crews. For the first time, quality control issues in the filming process of small-budget films are explained from the perspective of project quality factor. Among the six factors affecting film quality during film production management – costumes, makeups, props and set-ups, scenes, production, and actors – actors play the key role.

Lipid classes and fatty acid compositions of the farmed (F-C. gigas) and wild (W-C. gigas) pacific oysters, Crassostrea gigas, in Nha Trang, Vietnam were investigated for the first time. The results indicated that the lipid classes and fatty acid components of these oysters were insignificantly different. The total lipid of both studied oysters included six lipid classes, namely phospholipid (PL), sterol (ST), free fatty acid (FFA), triacylglycerol (TG), monoalkyldiacylglycerol (MADG), and hydrocarbon-wax (HW) in which TG and PL were dominated with the values of 48.4%, 41.8% for TG and 19.0%, 20.3% for PL in F-C. gigas and W-C. gigas, respectively. The fatty acids (FAs) content of F-C. gigas and W-C. gigas was similar. The saturated fatty acids (SFAs) content was 48.2% in total fatty acids (TFAs) of the F-C. gigas and 44.7% in TFAs of W-C. gigas, in which 16:0 was dominated in SFAs of both oysters with the value of 24.2% in F-C. gigas and 22.0% in W-C. gigas. The contents of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) were 18.3%, 20.5% for MUFAs and 31.7%, 34.7% for PUFAs respectively in F-C. gigas and W-C. gigas. These MUFAs compositions contained 16:1n-7, 16:1n-5, 18:1n-9, 18:1n-7, 20:1n-11, 20:1n-9 and 20:1n-7, among them fatty acids 16:1n-7 (7.2% in F-C. gigas, 6.3% in W-C. gigas) and 18:1n-7 (6.6% in F-C. gigas, 7.4% in W-C. gigas) were the main MUFAs. PUFAs in these two oysters consisted of long-chain n-3 and n-6 fatty acids, in which 20:5n-3 (EPA) and 22:6n-3 (DHA) were dominated with the values of 12.7%, 13.9% for EPA in F-C. gigas and 6.5%, 6.0% for DHA in W-C. gigas.

Grassland with tradition: sampling across several scientific disciplines

The traditional, low-input use of grassland in Central and Eastern Europe has provided high-quality food, clothing and manure for millennia. As an outcome of sustainable low-intensity agriculture, some rural areas have globally significant species richness. Traditional farming is still well preserved in several regions of the Carpathian Mountains. This is a unique opportunity to use the wisdom of our ancestors to keep grassland biodiversity for our descendants. We present a sampling methodology to survey traditionally managed grassland ecosystems holistically, including abiotic, biological and cultural phenomena, and reflect thus the multidimensionality of traditional farming. Our main objective was to reveal the connection between particular management practices and precisely measured plot plant diversity. Our motivation was to identify traditional farming approaches that result in both high biodiversity and sustainable grassland utilization in particular region, and confirm their impact also using statistical tests. The multitaxon vegetation sampling at seven spatial scales combined with soil analyses, detailed land-use information derived from interviews with the land parcel owners, satellite pictures and historical materials provide potentially valuable data for several scientific disciplines including syntaxonomy, plant ecology, environmental anthropology and ethnology. Examples of grassland management practices based on traditional ecological knowledge can serve as an inspiration for developing modern biodiversity conservation strategies applicable for rural regions. The database Grassland with Tradition is registered in Global Index of Vegetation-Plot Databases (GIVD) with the identifier ID EU-00-032. To date it contains data from 31 study sites in 7 countries (Austria, Czech Republic, Slovakia, Hungary, Poland, Romania, Ukraine). Syntaxonomic reference: Mucina et al. (2016).
Classification of Wing Chun Basic Hand Movement using Virtual Reality for Wing Chun Training Simulation System

A R T I C L E I N F O A B S T R A C T Article history: Received: 02 October, 2020 Accepted: 28 December, 2020 Online: 15 January, 2021 To create a Virtual Reality (VR) system for Wing Chun's basic hand movement training, capturing, and classifying movement data is an important step. The main goal of this paper is to find the best possible method of classifying hand movement, particularly Wing Chun's basic hand movements, to be used in the VR training system. This paper uses Oculus Quest VR gear and Unreal Engine 4 to capture features of the movement such as location, rotation, angular acceleration, linear acceleration, angular velocity, and linear velocity. RapidMiner Studio is used to pre-process the captured data, apply algorithms, and optimize the generated model. Algorithms such as Support Vector Machine (SVM), Decision Tree, and kNearest Neighbor (kNN) are applied, optimized, and compared. By classifying 10 movements, the result shows that the optimized kNN algorithm obtained the highest averaged performance indicators: Accuracy of 99.94%, precision of 99.70%, recall of 99.70%, and specificity of 99.97%. The overall accuracy of the optimized kNN is 99.71%.
THE ROLE OF MIGRATION IN HUMAN CAPITAL DEVELOPMENT ESPECIALLY IN NIGERIA: A REVIEW OF EVIDENCE

The issue of the role of migration in human capital development is descriptively examined in this write-up. Human capital refers to the quality of population expressed in terms of education, skills and health and developed through investment in education and training. The people involved in migration are migrants and the money they remit home is referred to as remittances. Apart from the direct involvement of these migrants in education related projects and education and training of children and relatives left behind in the home regions as this paper affirm, the expenditures of money remitted home from the migrants by families left behind are essentially on education food purchase and health issues, thus advancing the course of human capital development. It is therefore recommended that government find a way of noticing, recognizing and encouraging the efforts of migrants so as to spur further positive action in this regard.
Kimpul (Xanthosoma sagittifolium) liquid sugar with a low glycaemic index

Kimpul (Xanthosoma sagittifolium) is one type of local tuber plant that has high carbohydrate content (34.2 g/100g). This plant provides an opportunity to be utilized as an alternative source of sugar. The use of kimpul as liquid sugar becomes an alternative sweetener that needs testing from the perspective of nutrition and health. The Glycaemic Index (GI) is a term that is closely related to carbohydrate metabolism, which has the index (level) of food according to its effect on blood glucose levels. The study of the formulating process of kimpul liquid sugar that has a lower GI attempts the use of sugar from kimpul can be more appropriate and well-targeted. This study aimed to determine the engineering process to decrease the GI value of liquid sugar from kimpul through the treatment of tea extract addition and identify the nutritional value, calorific value, GI value, and tannin content in the kimpul liquid sugar as the result of the engineering process. The results showed that the addition of black tea extract with a 2% concentration could reduce the GI value of the kimpul liquid sugar. Thus, kimpul liquid sugar can use as a source of natural sugar with a low GI.
Electronic and Magnetic Structure Study of NiV2O4

Inspired by recent experiments and theoretical work on vanadium spinels, the least investigated vanadium spinel i.e. NiV2O4 has been explored theoretically in this work. The systems is found to have an optimized vanadiumvanadium distance of 2.94 Å , which is the same as the limit of itinerancy in vanadium spinels. This indicates that the system is sitting exactly at the border between metallic and insulating phase. The calculations show that there is no tetragonal distortion present in it and it would prefer normal spinel structure. The DFT calculations have been performed using GGA approximation.
