Evaluation of Nonconventional Extraction Methods of Resveratrol from
Various Plant Sources - A Brief Review
Authors: Saidul Sk , Das Susmita , Hoda Muddasarul 
Published: May 2023

Abstract:
Resveratrol is a stilbene class of phenolic phytochemical that has a wide range of utilization in
several industries, including pharmaceutical, food and cosmetic industries. It is available in several plants,
including grapes, berries, and peanuts. Major focus of research regarding resveratrol has been its therapeutic potential against major diseases, including cardiovascular, inflammatory, cancer, microbial and
age-related diseases. However, its extraction methods have not been of much discussion. In this review,
nonconventional methods, including supercritical fluid extraction, subcritical water extraction, microwave-assisted extraction, ultrasound assisted extraction, and high hydrostatic pressure extraction have
been discussed in contrast to widely implemented conventional extraction methods. Nonconventional
methods are considerably advanced over conventional methods. In this review, the efficiency of various
nonconventional methods via optimization of their extraction parameters, such as the effects of modifiers,
solvents, pressure, temperature, and extraction time, have been evaluated. Improvised extraction methods
may result in cost-effective isolation of resveratrol.
Improving Intelligence Metrics using Frequency Domain Convolutions for
Improving Bug Prediction
Authors: Mishra Anurag , Sharma Ashish 
Published: May 2023

Background:
The novelty of the work lies in the formulation of these frequency-based
generators, which reflects the lowest level of information loss in the intermediate calculations. The
core idea behind the approach presented in this work is that a module with complex logic involved
may have more probability of bugs. Software defect prediction is the area of research that enables
the development and operations team to have the probability of bug proneness of the software. Many
researchers have deployed multiple variations of machine learning and deep learning algorithms to
achieve better accuracy and more insights into predictions.

Objective:
To prevent this fractional data loss from different derived metrics generations, a few optimal
transformational engines capable of carrying forward formulations based on lossless computations
have been deployed.

Methods:
A model Sodprhym has been developed to model refined metrics. Then, using some classical
machine learning algorithms, accuracy measures have been observed and compared with the
recently published results, which used the same datasets and prediction techniques.

Results:
The teams could establish watchdogs thanks to the automated detection, but it also gave
them time to reflect on any potentially troublesome modules. For quality assurance teams, it has
therefore become a crucial step. Software defect prediction looks forward to evaluating error-prone
modules likely to contain bugs.

Conclusion:
Prior information can definitely align the teams with deploying more and more quality
assurance checks on predicted modules. Software metrics are the most important
component for defect prediction if we consider the different underlying aspects that define the defective
module. Later we deployed our refined approach in which we targeted the metrics to be considered.

Authors: Ninik Anisah  
Published: May 2023

The Covid-19 pandemic has reduced economic growth in West Java, including investment growth explained by the decline in economic growth in the Gross Fixed Capital Formation component. Moreover, the primary measure that illustrates the economic region shows how much monetary value is formed to Gross Regional Domestic Product. This study looks at the investment conditions of Foreign Direct Investment, Domestic Direct Investment, and Government Capital Expenditures before and during the Covid-19 pandemic and the effect of these investments on the Regional Economic. The multiple regression analysis methods use the data to cross-section with individual districts and cities in West Java Province and the three investment variables. The analysis results explain that the Covid-19 pandemic has reduced Foreign Direct Investment and Government Capital Expenditure, on the other hand, increased Domestic Direct Investment. This increase in Domestic Direct Investment is related to the new businesses that are strongly related to the handling of the Covid-19 pandemic. Domestic Direct Investment and Government Capital Expenditure are still being felt on the region's economy before and during the Covid-19 pandemic, but Foreign Direct Investment has decreased. Before the Covid-19 pandemic, the real impact of Foreign Direct Investment came from the first and second years after investment. In contrast, during the Covid-19 pandemic, the real impact came from three years after invested Foreign Direct Investment.

Authors: Wang Wei , Zheng Jingli 
Published: May 2023

Abstract
In order to solve the problem that a large number of low-value and easy-to-consume graphic designs consume the human and financial resources of the society and also waste the inherent value of design resources, by dividing the layers of pixels, elements, relations, planes and applications, this article defines the corresponding feature representations and studies related methods for quantifying geometric features, perceptual features and style features. The content includes the extraction method of element colour, the calculation method of layout-aware feature and colour-match-aware feature, and the pairwise comparison method of style feature. The experimental results show that the method proposed in this article has lower complexity and is significantly better than other algorithms. Comparing the method proposed in this article with other methods, the average time of this algorithm is 2.6 s under the condition of guaranteed images. The study of the design feature-driven graphic image style calculation method is not only of great significance for solving repeated design problems but also provides a basis and reference for the future development of intelligent design.

Abstract
This study aimed to investigate the effect of dietary n-3 fatty acids and ginger (Zingiber officinale) supplementation on semen quality, sperm fatty acids, and reproductive performance of roosters. Seventy-two roosters (30 weeks old) were randomly allocated into 4 dietary treatments including 1) basal diet as the control group (F0G0), 2) basal diet supplemented with 20 g/kg fish oil (F2G0), 3) basal diet supplemented with 30 g/kg ginger powder (PG) (F0G3), and 4) basal diet supplemented with 20 g/kg fish oil and 30 g/kg ginger powder (F2G3) for 10 consecutive weeks. The levels of sperm linolenic acid, EPA, and DHA were higher in fish oil-fed roosters (P<0.05). A lower percentage of sperm linoleic and arachidonic acids were recorded in F2G0 and F2G3 groups (P<0.05). At 38 weeks of age, a higher sperm volume was found in F0G3 roosters than in the F0G0 and F2G0 groups. From week 34 to the end of the experiment, sperm viability, sperm abnormality, and sperm motility were significantly improved in the GP-fed roosters (F0G3 and F2G3 groups) (P<0.05). Significantly lowest sperm concentration overall the experiment was observed in the F2G0 group (P<0.05). Higher testosterone levels and lower malondialdehyde (MDA) content were recorded in F0G3 and F2G3 groups in comparison to the F2G0 (P<0.05). Also, the fertility rate of collected eggs from F0G3 and F2G3 groups was higher compared to F2G0 group (P<0.05). In conclusion, although the use of fish oil in roosters’ diets alone had a negative effect on some parameters related to reproductive performance, the use of ginger powder alone or along with fish oil improved semen quality and fertility potential.
The effect of raw, hydrobarothermally treated and fermented rapeseed cake on plasma biochemical parameters, total tract digestibility and gut function in laying hens
Authors: Orlich Magdalena , Drażbo Aleksandra , Ognik Katarzyna , Rogiewicz Anna , Juśkiewicz Jerzy 
Published: May 2023

Abstract
This study evaluated the effects of inclusion of raw, hydrobarothermally treated and fermented rapeseed cake (RRC, HRC and FRC, respectively) in diets fed to laying hens. Hydrobarothermal treatment decreased the hydroxyglucobrassicin and neoglucobrassicin content of rapeseed cake (RC), whereas fermentation significantly reduced the content of all glucosinolates (GLS) and phytate phosphorus (PP) concentration. Both HRC and FRC increased the serum concentrations of total protein (TP) and globulin (GLB), compared with group C. Group HRC hens had desirably lowest blood triacylglycerol (TAG) levels and aspartate aminotransferase (AST) activity. Group FRC hens were characterized by the lowest alkaline phosphatase (ALP) activity, and the highest concentrations of phosphorus (P) and triiodothyronine (T3). Regardless of its form, RC improved ether extract (EE) digestibility, and decreased dry matter (DM) digestibility and calcium (Ca) retention. In comparison with group C, RRC, HRC and FRC decreased cecal digesta weight and enhanced the activity of bacterial α-galactosidase and ß-galactosidase; HRC also increased ammonia concentration in the ceca and reduced β-xylosidase activity. The activity of α-glucosidase and α-arabinopiranosidase was highest, and the activity of bacterial β-glucuronidase was lowest in the ceca of group FRC hens. The cecal concentrations of acetic acid, propionic acid, and total short-chain fatty acids (SCFA s) were highest in birds fed a diet containing RRC and lowest in group HRC. In conclusion, RC fermentation considerably reduces the concentrations of GLS and PP. A diet containing 20% FRC is more recommended than diets containing RRC and HRC because it exerted a beneficial effect on metabolic parameters and intestinal function in laying hens.

Published: May 2023

Abstract
Poultry production significantly contributes to bridging the food gap worldwide. Several nations have limited the usage of antibiotic growth promoters due to bacterial resistance to antibiotics and the occurrence of residual antibiotics in the edible tissues of birds. The world is now turning to using natural alternatives to increase poultry production as well as birds’ resistance to diseases. Withania somnifera (WS; family: Solanaceae) is a precious medicinal herb utilized in several countries due to its distinct chemical, medicinal, and physiological properties. This plant has antioxidant, anti-aging, antimicrobial, antitumor, hepatoprotective, cardioprotective, neuroprotective, immunomodulatory, antidiabetic, antistress, and growth-promoting activities. In poultry, the dietary inclusion of WS revealed a promising result in enhancing productive performance, increasing disease resistance, reducing stress effects, and maintaining the bird’s health. Thus, the current review highlights the morphological features, distribution, chemical structure, and pharmacological features of Withania somnifera as a growth promoter herb for farming broiler chickens.
Considerations For Scaling a Social Enterprise: Key Factors and Elements
Authors: O’Reilly Clodagh , Walsh Lucia , Mottiar Ziene 
Published: May 2023

Abstract
The number of social enterprises has grown exponentially in recent times. International research regarding how social enterprises scale is starting to emerge and is becoming an area of increased focus. Due to their hybridity, social enterprises experience unique scaling challenges, and research has started to examine these experiences. This theoretical paper reviews existing literature on social enterprise scaling and, based on this, proposes a conceptual model for understanding the interdependent factors and elements social enterprises must navigate when scaling. The proposed conceptual model will provide a base for further empirical research. When validated, it will also provide a practical tool for social enterprises exploring scaling possibilities and inform future enterprise and policy supports in this area.
Effect of the Acute Total Gamma Radiation in a Sublethal Dose on the Biophysical Properties of Red Blood Cells, Lipid Peroxidation, Antioxidant Supply and Hemocoagulating Properties of Erythrocytes
Authors: Zaporozhets Tetiana , Korovina Lidiia , Sanyk Oleksandr 
Published: May 2023

Abstract
The aim of the investigation was to study the effect of acute, total gamma-irradiation in a sublethal dose on the biophysical properties of erythrocytes, the intensity of lipid peroxidation, antioxidant supply and hemocoagulating properties of erythrocytes. The experiments were carried out on 11-12-week-old age guinea pigs, males and females in equal numbers. The animals were exposed to a single total radiation at a dose of 4.5 Gy (sublethal dose, LD 50/30). The studies were carried out on the 7th day after exposure to radiation (at the height of radiation sickness). The development of radiation damage was accompanied by intense erythropoiesis and the appearance of erythrocytes with a high resistance to hemolysis and an increased sedimentation rate. After acute gamma irradiation, depletion of the antioxidant system was noted. It manifested in a decrease in the activity of superoxide dismutase of erythrocytes by 19.7% (p<0.01) and the concentration of serum ceruloplasmin by 21.5% (p<0.01). The content of thiobarbituric acid reactive substances (TBARS) and their accumulation while the incubation of erythrocytes remained within the normal range. The erythrocytes of the irradiated animals exhibited increased procoagulant and decreased antiheparin activity, which reflects conformational changes in highly radiosensitive fatty acid chains of phospholipids in their membranes. A decrease in the fibrinolytic activity of erythrocytes in irradiated animals was found.
