Authors: Atan Arzu , Ozgit Hale , Silman Fatos
Published: July 2021

Employment practices that support happiness at work are critical tools for developing a sustainable workforce. In today’s challenging environment, both economically and environmentally, the contribution of a sustainable workforce, which is the most critical asset for hospitality businesses to survive and succeed, cannot be ignored. This study explores the effects of motivational dimensions on happiness at work. These relationships were evaluated using the SPSS for Windows 25.0 and AMOS 23.0 programs. For this purpose, data were collected from 271 female employees in various four- and five-star hotels in North Cyprus. As predicted, the results revealed that motivational dimensions affect the dimensions of happiness at work. This study confirmed that a better understanding of employees’ needs and demands would encourage motivation and result in happier employees. The findings offer important implications for hospitality industry organizations seeking to maximize employee happiness in the workplace and strive for the sustainability of their workforce.

There is a worldwide trend that supports the rational use of chemicals in agriculture. It has become common knowledge that irresponsible application of pesticides can cause food security issues, by endangering human and animal health while also having negative environmental consequences. The aim of this experiment was to assess the qualitative parameters of spraying treatments in vineyards. To achieve this, a vineyard and orchard sprayer machine was used for the application of treatments under a gradient of pressures (3, 5, 7, 9 bar). Water-sensitive collectors were placed at three heights (0.8 m, 1.5 m, 2.5 m). Following spraying was determined using DepositScan: the volume median diameter characterization of droplets (DV 1, DV 5, DV 9), and coverage degrees of sprayings. Results indicated that best coverage degree and larger droplets tend to be deposited 1.5 m from the ground, which corresponds with the highest proximity to the positioning of the nozzles of the machine during application, and lowest coverage is found at the top, where droplets deposited also tend to be smaller. For the anti-drift nozzle model used in the study, the best coverage was obtained at a pressure of 5 bar. For sustainability of agricultural practices and rational use of pesticides, more research is required for optimization of increased precision spraying that could ensure high coverage at lower doses of chemicals and coarse droplets. In this way the quantity of product sprayed is expected to be reduced, due to minimization of off-target losses and increased efficiency. This can ensure that negative environmental impacts are lowered. Improved treatment application at higher positioning of the canopy remains a challenge and shall receive more attention.

Hantaviruses are harbored by multiple small mammal species in Asia, Europe, Africa, and the Americas. To ascertain the geographic distribution and virus-host relationships of rodent-borne hantaviruses in Japan, Vietnam, Myanmar, and Madagascar, RNAlater™-preserved lung tissues of 981 rodents representing 40 species, collected in 2011–2017, were analyzed for hantavirus RNA by RT-PCR. Our data showed Hantaan orthohantavirus Da Bie Shan strain in the Chinese white-bellied rat (Niviventer confucianus) in Vietnam, Thailand; orthohantavirus Anjo strain in the black rat (Rattus rattus) in Madagascar; and Puumala orthohantavirus Hokkaido strain in the grey-sided vole (Myodes rufocanus) in Japan. The Hokkaido strain of Puumala virus was also detected in the large Japanese field mouse (Apodemus speciosus) and small Japanese field mouse (Apodemus argenteus), with evidence of host-switching as determined by co-phylogeny mapping.
Improved Specificity and Safety of Anti-Hepatitis B Virus TALENs Using Obligate Heterodimeric FokI Nuclease Domains
Authors: Smith Tiffany , Singh Prashika , Chmielewski Kay Ole , Bloom Kristie , Cathomen Toni , Arbuthnot Patrick , Ely Abdullah
Published: July 2021

Persistent hepatitis B virus (HBV) infection remains a serious medical problem worldwide, with an estimated global burden of 257 million carriers. Prophylactic and therapeutic interventions, in the form of a vaccine, immunomodulators, and nucleotide and nucleoside analogs, are available. Vaccination, however, offers no therapeutic benefit to chronic sufferers and has had a limited impact on infection rates. Although immunomodulators and nucleotide and nucleoside analogs have been licensed for treatment of chronic HBV, cure rates remain low. Transcription activator-like effector nucleases (TALENs) designed to bind and cleave viral DNA offer a novel therapeutic approach. Importantly, TALENs can target covalently closed circular DNA (cccDNA) directly with the potential of permanently disabling this important viral replicative intermediate. Potential off-target cleavage by engineered nucleases leading to toxicity presents a limitation of this technology. To address this, in the context of HBV gene therapy, existing TALENs targeting the viral core and surface open reading frames were modified with second- and third-generation FokI nuclease domains. As obligate heterodimers these TALENs prevent target cleavage as a result of FokI homodimerization. Second-generation obligate heterodimeric TALENs were as effective at silencing viral gene expression as first-generation counterparts and demonstrated an improved specificity in a mouse model of HBV replication.

Anthropogenic Organic Pollutants in Groundwater Increase Releases of Fe and Mn from Aquifer Sediments: Impacts of Pollution Degree, Mineral Content, and pH
Authors: Zhai Yuanzheng , Han Yifan , Xia Xuelian , Li Xindai , Lu Hong , Teng Yanguo , Wang Jinsheng
Published: July 2021

In many aquifers around the world, there exists the issue of abnormal concentrations of Fe and Mn in groundwater. Although it has been recognized that the main source of this issue is the release of Fe and Mn from aquifer sediments into groundwater under natural environmental conditions, there lacks enough reliable scientific evidence to illustrate whether the pollutants imported from anthropogenic activities, such as organics, can increase this natural release. On the basis of time series analysis and comparative analysis, the existence of an increasing effect was verified through laboratorial leaching test, and the impacts of aquatic chemical environment conditions, such as pH, on the effect were also identified. The results showed that the increase of organics in groundwater made the release of Fe and Mn more thorough, which was favorable for the increase of groundwater concentrations of Fe and Mn. The higher the contents of Fe- and Mn-bearing minerals in aquifer sediments, the higher the concentrations of Fe and Mn in groundwater after the release reaches kinetic equilibrium. Lower pH can make the leaching more thorough, but the neutral environment also increases the amount of Mn. It can be deduced that the pollutants such as organics imported by anthropogenic activities can indeed increase the releases of Fe and Mn from aquifer sediments into groundwater, thus worsening the issue of groundwater Fe and Mn pollution. The findings provide a deeper insight into the geochemical effects of Fe and Mn in the natural environment, especially in the groundwater system.
Effects of Zeolitic Urea on Nitrogen Leaching (NH4-N and NO3-N) and Volatilization (NH3) in Spodosols and Alfisols
Authors: Ahmad Ayaz , Ijaz Shahzada Sohail , He Zhenli
Published: July 2021

Global use of urea nitrogen (N) fertilizer is increasing, but N losses are still very high (40–70%). Zeolites have the capability of holding NH4+, thus reducing N losses when applied as a soil amendment. However, application of a large quantity of zeolite is costly and inconvenient. In this study, zeolitic fertilizers were evaluated to select the best formulation with reduced leaching of NH4-N and NO3-N and NH3 volatilization in agricultural soils (Alfisol and Spodosol). The treatments included the following: T0 = control, T1 = urea fertilizer, T2 = zeo-urea (1:1), T3 = zeo-urea (2:1), T4 = zeo-urea (3:1), T5 = zeo-urea (1:2), and T6 = zeo-urea (1:3). Leaching was performed at 4, 8, 12, 19, 25, 32, 39 and 45 days after the soils were treated with the designated fertilizers, including control, and packed into columns. Leachate samples were collected after each leaching event and analyzed for the concentrations of NH4-N and NO3-N and the quantity of leachate. Ammonia volatilization was recorded at days 1, 5, 9, 13 and 20 of soil treatments. Results indicate that zeolitic fertilizer formulations effectively reduced N losses. NH4-N loss was reduced by 13% and 28% by zeo-urea (1:1) in Alfisol and Spodosol soils, respectively, whereas zeo-urea (2:1) and zeo-urea (3:1) effectively decreased NO3-N leaching in Alfisol. Volatilization loss of NH3 was reduced by 47% in Spodosol and 32% in Alfisol soil with zeo-urea (1:1) as compared with that of urea fertilizer. The results suggest that zeo-urea (1:1) is an effective fertilizer formulation for reducing N losses, especially in Alfisol, as compared with conventional urea fertilizer.
Gobiernos Locales en Bolivia

Published: July 2021

El objetivo de la investigación fue analizar la situación de los Gobiernos Locales en lo que se refiere a los Gobiernos Autónomos Municipales (GAM) en Bolivia, especialmente de aquellos que cuentan con escasa población y recursos económicos, como línea de base para explorar soluciones de política pública que permitan mejorar las condiciones de vida de su población. Para esto, primero se describió el marco normativo de la creación y fusión de unidades territoriales (UT); a continuación, se muestra la evolución de la división territorial municipal en Bolivia (1995 – 2021); finalmente, se analizazon sus principales fuentes de financiamiento, el destino de su gasto y los problemas asociados con estas variables. Como resultado, se encontró que, en el ámbito económico, los GAM de menos de 5 000 habitantes tienen capacidades institucionales deficientes, a causa de: escasa población, falta de desarrollo decapacidades fiscales y dificultad para ejecutar recursos. Esto pone en cuestión su habilidad para cumplir con las garantías, mandatos y competencias asignadas a este nivel de gobierno en la Constitución Política de Estado (CPE), en áreas prioritarias para el desarrollo del Estado como son los sectores de salud y educación.

Les toponymes en khmer ancien.

Long Seam.

On relève dans les Inscriptions du Cambodge (IC) du VIe au XIVe siècle, environ mille cinq cents termes toponymiques.

Un grand nombre d'entre eux sont formés de termes du khmer ancien se rapportant au monde aquatique, botanique et animal. N'ayant pas subi de grands changements de structure, ils sont reconnus et compris par les locuteurs du khmer moderne, lesquels forment leurs toponymes selon les mêmes schémas mentaux. Après en avoir dressé un inventaire raisonné, nous analysons ici leur morphologie et leur structure sémantique. Dans un second temps, nous analyserons les toponymes formés sur des racines sanskrites dont la structure est tout à fait différente de celle des toponymes purement khmers.

L'ensemble de ces toponymes constitue une source d'information importante sur les réalités socio-économiques et culturelles de l'ancien Cambodge. C'est ce dernier aspect que nous traiterons en conclusion.

Introduction

Building on Southeast Asian examples, this series argues in favour of a dynamic and relational approach to ethnicity, which breaks with the simplifying opposition between relations of meaning and power struggles, as well as with the shortcomings of the primordialist and instrumentalist theories. Contrary to these paradigms, the various contributions presented here assume 1) that ethnicity, to be understood as series of interethnic processes, partly systematized in their ideational and relational dimensions, can be either an end in itself or a means to achieve other ends ; 2) that the manipulation of shared symbols and concepts, related to cultural interfaces, is frequently associated with ethnicity ; 3) that the ends pursued by the interacting groups are not necessarily in competition ; 4) that ethnicity is a process of constantly renewed compromises between cultural dispositions and unprecedented situations ; 5) and that collective mobilizations and competitions may oppose segments or fractions of the society, as much as a whole society against its neighbours.
Note sur l’orientation des monuments en Asie du Sud-Est
Authors: Pichard Pierre
Published: July 2021

In Southeast Asia, the orientation of ancient monuments commonly said to be “ open to the east” differs frequently from the true east, by being either northward or southward. Most of them could have been originally oriented toward the rising sun, and by measuring their angular deviation from true east it becomes possible to calculate two days, one of them being the approximate day of their foundation (however one cannot compute the specific year). On the other hand, when the axis of a monument concurs exactly with the eastward direction, either the monument was laid out with a gnomon or by aiming at the rising sun on an equinox day.
A Dvāravatī Votive Tablet Reconsidered
Authors: Woodward Hiram W.
Published: July 2021

A Dvāravatī votive tablet was originally identified as a depiction of the Buddha’s miracle of double appearances ; more recently, the subject has been called the Eight Great Bodhisattvas or, simply, a Buddhist assembly. In this brief article it is proposed, on the basis of literary evidence, that the subject is “ Under the Rājāyatana Tree, the Buddha Visits the Kingdom of the Nāgas, Awaited by Bodhisattvas on the Bordering Mountain.” The identification, if correct, has implications for the understanding of the relations between Sri Lanka and Dvāravatī in the seventh to eighth centuries.
Frontières internes de l’ethnie : deux exemples tibéto-birmans
Authors: Bouchery Pascal
Published: July 2021

Doit-on, dans l’analyse des phénomènes identitaires, considérer tout contenu culturel comme secondaire ? Peut-on considérer, à la suite de Barth, que l’interaction constitue le mécanisme privilégié à travers lequel se réalisent attributions et identifications et que les processus relationnels — non les cultures — construisent à eux seuls les identités ? L’identification ethnique peut-elle s’exercer à partir de n’importe quoi ? À travers la mise en perspective de deux sociétés de l’Asie du Sud-Est continentale regroupant chacune quelques centaines de milliers de personnes, les Hani du Yunnan méridional d’un côté, et les Naga du Nord-Est indien de l’autre, nous proposons ici d’éclairer comment certains éléments relevant de ce que Godelier qualifierait volontiers de «noyau dur » d’une culture interviennent de façon prégnante dans la construction identitaire d’un groupe ethnique, indépendamment des relations que celui-ci entretient avec l’extérieur. Pour cela, nous nous intéresserons plus particulièrement aux frontières internes de l’ethnie, un aspect relativement négligé par Barth mais qui présente pourtant un avantage méthodologique : celui de permettre la mise en évidence, au sein d’un ensemble culturel relativement homogène, d’éléments structurels agissant comme facteurs de cohésion — ou à l’inverse de fragmentation — des unités sociales, révélant par là même leur rôle structurant dans les logiques unitaires ou au contraire les tensions internes qui motivent et affectent les identités.
The US Central Intelligence Agency and the Brao. The Story of Kong My, a Non-Communist Space in Attapeu Province, Southern Laos
Authors: Baird Ian G.
Published: July 2021

Pendant la guerre du Viêt-nam, on a assisté au Laos à la naissance de lignes d’allégeance politique reflétant l’antagonisme idéologique au coeur de la guerre froide, lesquelles ont eu pour corollaire l’apparition de divisions territoriales. Ainsi, dans l’est de la province d’Attapeu, la zone frontalière entre le Laos et le Cambodge était-elle divisée de façon officieuse en deux espaces administratifs, l’un communiste, l’autre non : le Pathet lao et ses mentors communistes vietnamiens y avaient créé les districts de Phou Vong Neua et de Phou Vong Tai, tandis qu’un espace non communiste brao avait été constitué dans les montagnes jouxtant la Nam Kong — à Kong My (dans le district de Lave, qui relevait du gouvernement royal). Pendant toute la guerre, la frontière qui existait de fait entre ces deux espaces a fortement affecté la vie quotidienne des Brao. Centré sur Kong My, cet article analyse le rôle joué par la CIA auprès des Brao, tant du point de vue de ces derniers que de celui des Américains. Il traite par ailleurs de Tanh Homrasmy, un des principaux chefs brao de Kong My pendant les années 1960 et le début des années 1970 et de ses relations avec Kaysone Phomvihane dont il avait fait la connaissance à l’occasion des élections législatives de 1958 dans la circonscription d’Attapeu.
Les rites d’ « ordination » d’arbres : mise en scène de l’écologie indigène en Thaïlande
Authors: Pessès Abigaël
Published: July 2021

This paper describes and analyses a “ tree ordination” ceremony organized in 1999 by a network of Karen villages. “ Tree ordination” rituals were created quite recently ; they consist of the consecration of protected forest spaces symbolically offered to the King through procedures that combine Buddhism with various spirit cults belonging to local cosmologies. In the course of such spectacular “ stagings,” the tribute paid to the King creates a “ meeting space” that allows a peaceful dialogue between the main protagonists involved in the management of national forest resources : the monastic community ; the civil servants ; the forest wardens ; the NGOs ; small farmers of the plains and the hills ; their spokesmen ; and the media. The detailed study presented in this paper of the modalities of appropriation of this ritual by the Karen shows how this community— actually the main hill-tribe minority in Thailand— is striving to establish a new territorial status and identity that warrants them the right to keep living in the “ protected areas” controlled in an authoritarian way by the state.
El desarrollo de la Subsecretaría de Informaciones (1943-1945). Los primeros ensayos de política mediática de Perón antes del peronismo
Authors: Lindenboim Federico
Published: July 2021

El presente artículo indaga sobre la Subsecretaría de Informaciones y la política de radiodifusión implementada por el gobierno militar durante 1943-1945. En base a una diversidad de fuentes documentales, el artículo describe la construcción de estructuras estatales y sus diferentes modos de intervención en la radiofonía. Por un lado, se detiene en la Subsecretaría de Informaciones, por ser un organismo creado por los militares y porque fue un espacio de disputa política entre los miembros del gobierno. Además, desde esa entidad, un equipo de prensa organizado por el entonces coronel Perón logró presentar una política mediática con algunos matices en comparación con el accionar de otros militares. Por otra parte, se reconstruyen los distintos tipos de vínculos que se fueron edificando entre miembros del gobierno militar, propietarios de emisoras y las estrellas del espectáculo.

Published: July 2021

A escassez de insumos oriundos de recursos naturais e os impactos do processo de produção do cimento são razões para o desenvolvimento de alternativas mais sustentaveis. Reduzir o consumo de cimento é uma dessas alternativas, e isso pode ser feito reciclando materiais cimentícios hidratados por meio da reihratação. Por isso o objetivo desse artigo é compreender o processo de rehidratação de argamassas e concretos desidratados e os efeitos nas propriedades de novos materiais produzidos a partir desses produtos, por meio de revisão sistemática, identificando o mecanismo de reativação de fases hidratadas de argamssas e concretos. As buscas foram realizadas na base de dados da Science Direct no periodo de 2018 a 2019. A busca resultou em 31 artigos que apresentavam o processo de ativação do cimento hidratado e as propriedades de concretos e argamassas com cimento desidratado. A análise dos artigos permitiu compreender como as reações de desidratação e decomposição em pastas de cimento hidratada ocorrem. Foram ainda identificados os compostos formados após a degradção térmica e que é possivel a reação com a água formando produtos iniciais de hidratação tais como etringita, gel C-S-H e CH. Quanto ao desempenho de concretos e argamassas com esses produtos desidratados, ainda são necessárioa smais pesquisa. Mas já é de conhecimento que o melhor desempenho mecanico é alcançado quando essas fases são decompostas na faixa de 660 a 800ºC. É também relatada a baixa reatividade de concretos desidratados devido ao elevado teor de agregados em concretos. A pesquisa demonstrou que estudos ainda precisam ser realizados para viabilizar o uso de argamassas e concretos reidratados. Tais estudos podem agregar valor a um resíduo ainda com aplicações de recilagem restrita

Published: July 2021

To achieve the goal of collecting lunar samples and return to the Earth for the Chang’E-5 spacecraft, the lander and ascender module (LAM) of the Chang’E-5 spacecraft successfully landed on the lunar surface on 1 Dec., 2020. The guidance, navigation, and control (GNC) system is one of the critical systems to perform this task. The GNC system of previous missions, Chang’E-3 and Chang’E-4, provides the baseline design for the Chang’E-5 LAM, and the new characteristics of the LAM, like larger mass and liquid sloshing, also bring new challenges for the GNC design. The GNC design for the descent and landing is presented in this paper. The guidance methods implemented in the powered descent are presented in detail for each phase. Propellant consumption and hazard avoidance should be particularly considered in the design. A reconfigurable attitude control is adopted which consists of the quaternion partition control, phase and gain stabilization filter, and dual observer. This controller could provide fast attitude maneuver and better system robustness. For the navigation, an intelligent heterogeneous sensor data fusion method is presented, and it is applied for the inertial measurement unit and velocimeter data. Finally, the flight results of the LAM are shown. Navigation sensors were able to provide valid measurement data during descent, and the thrusters and the main engine operated well as expected. Therefore, a successful soft lunar landing was achieved by the LAM.

Published: July 2021

Background: Dust particles are one of the most important environmental problems that are threatening many countries, and patients with cardiovascular diseases (CVDs) are a vulnerable group in this respect. The present study was conducted to examine the protective strategies among patients with CVDs against exposure to dust phenomenon based on the protection motivation theory (PMT). Methods: This cross-sectional study was performed on 183 patients with CVDs who referred to health care centers in Ahvaz city, Khuzestan province, southwest of Iran. Participants were selected from patients with CVDs recruited for routine national Package of Essential Non-communicable Disease (IRA-PEN) through random cluster sampling. Data were collected using a researcher-made questionnaire based on the PMT. Data were analyzed using descriptive and analytical tests such as Pearson correlation coefficient and multiple linear regressions by SPSS version 22. Results: The mean scores of the constructs of perceived response efficacy (4.06 ± 20.06) and sensitivity (19.89 ± 4.30) were higher than those of other constructs. Correlation coefficient test showed a significant positive correlation between risk behaviors of exposure to dust phenomenon and self-efficacy, response efficacy and protection motivation, but negatively correlated with cost response. Also, self-efficacy variable, type of health insurance, and protection motivation were the predictive indicators of behavior. Conclusion: The constructs of the PMT explained the risk reduction behaviors of exposure to dust phenomenon in patients with CVDs. Therefore, this theory can be used as a framework for designing educational programs to increase the motivation of patients with CVDs to adopt risk reduction behaviors for exposure to dust.
Activity of acetylcholinesterase (AChE) in male albino rats exposed to metal welding fumes in an experimental setting
Authors: Sani Ali , Abdullahi Ibrahim Lawal , Ibrahim Sani
Published: July 2021

Background: There are millions of workers in the world, who engage in activities associated with welding operations but are not classified as full-time metal workers. The present study aimed to determine the activity of acetylcholinesterase (AChE) in blood of laboratory animals exposed to welding fumes. Methods: Welding fumes were obtained from Kofar Ruwa, Kano by a skilled welder. 130 albino rats were purchased from the Animal Section of Department of Biological Sciences and were divided into 12 groups. They were given doses equivalent to the workers’ real life exposure regimes, and 1 group was selected as control group. They were administered intratracheally following anesthetization once weekly for twelve weeks. The rats were euthanized and serum samples were collected. Then, AChE activity was evaluated spectrophotometrically using ELISA kit (Sunlong Biotech Company). Results: The mean values of AChE ranged from 23.1 to 25.05 ng/mL with the control having a value of 24.7 ng/mL. Thus, there was a decrease in the values of AChE in the blood of treated groups, which was significantly different from the control (P<0.05). Conclusion: Metal welding fumes negatively affected the AChE by reducing its mean values. This implies that welding fumes possesses neurotoxic effects, which can lead to some neurodegenerative diseases.

Published: July 2021

Auditor switching is a change of public accountant (or accounting firm) in a company. The voluntary auditor switching is carried out according to the client’s request to change his auditor, and no regulations require him to switch auditors. This study analyzes the factors influencing voluntary auditor switching in manufacturing companies listed on the Indonesia Stock Exchange in 2017-2019. This research population is all manufacturing companies listed on the Indonesia Stock Exchange in 2017-2019. The research sample was selected using a purposive sampling method. The sample amounted to 98 manufacturing companies, and the total sample was 294 company units. The analytical tool used to test the hypothesis is logistic regression analysis. The results showed that audit fees and audit tenure had a positive effect on auditor switching. Audit opinion, going concern opinion, and audit reporting lag do not affect auditor switching.

Effect of gas flow rate on breakdown voltage in a rotating gliding arc reactor
Authors: J Ananthanarasimhan , Rao Lakshminarayana
Published: July 2021

Understanding breakdown phenomena in rotating gliding arc discharge (RGA) is of interest to tailor them for specific applications. This work revealed that the breakdown voltage in a RGA reactor was not dictated by collisional effects i.e., change in flow rate. The observation was consistent for both the discharge gas medium argon and nitrogen. The collisional effect variation was implemented by varying the operating flow rates i.e., 5 SLPM which is transitional in nature, and 50 SLPM which is turbulent in nature having localized micro-eddies. The observation also indicated failure of Paschen law in RGA having shortest gap between the electrodes of order of mm, operated under atmospheric pressure conditions. Collisional ineffectiveness indicates possibility of streamer formation which needs to be further investigated in future. This work marks preliminary and important step towards understanding the breakdown phenomena in atmospheric RGAs operated under different flow regimes such as laminar/transitional and turbulent.
Contrasting mineralogy and strain partitioning across N-S oriented Sitampundi - Kanjamalai Shear in Sitampundi Anorthosite Layered Complex
Authors: M.K Harish , J Rahul , V Thirukumaran
Published: July 2021

Sitampundi Anorthosite Layered Complex (SALC) is a complexly folded and metamorphosed terrain that shows different metamorphic grade separated by a regional linear divide. In the north-eastern part of the complex, the anorthosites contain green-colored clinozoisites that are strikingly absent in the western part of the limb. Based on the presence of the clinozoisites, the entire SALC can be divided into two zones. The Sitampundi-Kanjamalai shear zone (SKSZ) separates mega crystals of clinozoite bearing anorthosites from clinozoisite free anorthosites. To add furthermore, strain analysis of different samples of anorthosite on either side of the zones was conducted by employing Flinn method. In general, anorthosites fall into the flattening field. The clinozoisite free anorthosites are more flattening and clinozoisite bearing anorthosites exhibit a slight difference in their strain ratio, ie., it is comparatively less flattening.  Geochemistry of clinozoisites was studied using EPMA & XRD methods. The percentage of oxides obtained from EPMA coincides with that of epidote. But, XRD confirms the mineral to be clinozoisite indicating the transition phase of epidote to clinozoisite. Zoning has had occurred in clinozoisites with aluminium oxide rich core and FeO rich rim. This could be related to a retrogression corresponding to a shearing event.

The ketogenic diet (KD), a restrictive diet, is mainly characterized by high-fat content, low or no carbohydrate content, and low or normal protein content. This review aimed to address the main syndromes or diseases in which the therapeutic use of KD can be beneficial. One of the main clinical indications of KD has been, for some time, in the treatment of epilepsy refractory to the use of medications, with satisfactory results in the control of seizures. Recently, studies have addressed the metabolism of ketone bodies caused by KD, in the adjuvant treatment of tumors and endocrine disorders, such as diabetes and obesity, with promising results. In this work, the therapeutic aspect of KD was analyzed, as an aid in the control of pre-existing diseases, and that being a very restrictive diet with controversial effects, its use may be limited and it is not advisable to maintain it for long periods or without the proper follow-up.

IMPLEMENTATION OF STEGANOGRAPHIC INFORMATION PROTECTION METHOD IN SOFTWARE DEVELOPMENT
Authors: Радынская В.Е.
Published: July 2021

Показано, что защита программных продуктов от несанкционированного использования является первостепенной задачей для разработчиков. Выделены три основные категории атак на программное обеспечение (ПО): нелегальное использование, обратная разработка, когда из ПО извлекаются наиболее ценные модули или части исходного кода, и модификация исходного кода, приводящая к существенным потерям для разработчиков, вплоть до потери авторских прав. Рассмотрен один из возможных способов защиты метод вложения цифрового водяного знака (ЦВЗ), основанный на использовании лингвистической стеганографии.

It is shown that the protection of software products from unauthorized use is a priority for developers. There are three main categories of attacks on modern software: illegal use, reverse development, when the most valuable modules or parts of the source code are extracted from the software, and modification of the source code, which leads to significant loss of developers, up to the loss of copyright. One of the possible methods of protection is the method of embedding a digital watermark, based on the use of linguistic steganography.
