This article presents data on the effect of processing avocado fruit on the dynamics of physiological and biochemical processes during low-temperature storage. The aim was to explore the effect of processing Fuerte avocado fruit with ‘Agrokhit’, ‘KHAN-8’ and ‘Extrasol-90’ preparations on the dynamics of physiological and biochemical processes during storage. The effectiveness of the preparations on the change in physiological and biochemical processes during storage of avocado fruit was evaluated by the release of carbon dioxide during their respiration, by the activity of terminal oxidases and the hydrolysis of pectin substances. The respiration rate, the activity of terminal oxidases – catalase, peroxidase, phenol oxidase, tyrosinase – and the kinetics of the hydrolysis of protopectin and pectin depended on the type of preparation and the duration of storage. Processing avocado fruit with the examined preparations did not violate metabolism, which was regulated by change in the activity of terminal oxidases of the plant cells, a reduced respiration rate and the rate of hydrolysis of protopectin and pectin. As a result, there was an increase in the storage period and fruit ripening. To slow down the physiological and biochemical processes – to increase the duration of ripening and storage of avocado fruit – it is recommended that they be treated with chitin derivatives Agrokhit and KHAN-8.
Georgian Military Road: Constant Communication (the Structure of “A Hero of Our Time” by M. Yu. Lermontov)
Authors: Dmitrovskaya Maria
Published: November 2020

The article demonstrates the fact that the duality of human consciousness is connected by mutual projections with the topography of the Georgian Military Road and the model of the universe and also forms the system of narrators / characters and the structure of the novel as a whole, including the number of stories and the partition of the novel into two parts. The sources used by the writer in the formation of the narrative structure of the novel are reconstructed. The numerological code of the novel is considered, the language bases of the conceptual system are analyzed. The embeddedness in the conceptual system of the trinomial name of Mikhail Yuryevich Lermontov is demonstrated. The vertical and horizontal spatial orientation of the Georgian Military Road allows discovering the topographic connection of the road with the dual reality of Lermontov, in which the opposite poles of good and evil, divine and evil turn into one.

Chekhov, was also shaped by the all of the human experience gained during this tragic stage of her life.
Osip Mandelstam in the French Anthologies of Russian Poetry (1925–1970)
Authors: Gamalova Natalia
Published: November 2020

The fates and fortunes of any national literature in a foreign culture is a multifaceted subject. And this is where the perception of Russian culture in France belongs. In France, the general public became aware of the life and works of Osip Mandelstam in the early seventies, when Nadezhda Mandelstam’s memoirs were published. Before 1970, only some translations of Mandelstam’s poems, the first one made by Chuzeville back in 1925, found their way to periodicals and anthologies. Information about the poet was spread to a great degree thanks to anthologies, as befits this genre of reading matter. During that period, the publishers of anthologies could either collaborate with translators (Slonim, Reavey), or translate the poetry themselves (Rais, Granoff). Journal articles and translations chime in and resonate with anthological publications.
Osip Mandelstam in the Works of Polish Poets
Authors: Brio Valentina
Published: November 2020

This article analyzes poems written by Polish authors about Osip Mandelstam. Fifteen poems by famous Polish authors, such as Artur Międzyrzecki, Wiktor Woroszylski, and Jarosław Marek Rymkiewicz, are examined. Polish poets perceive Mandelstam‘s tragic fate through the prism of the poet‘s image and significance of poetry as they appear in the context of the lives of the Polish literary and cultural tradition. These authors see Mandelstam as a martyr, an outstanding poet. To them, their mission is to bear testimony.
On Some Features of Osip Mandelstam’s Representation in the Memories by Anna Akhmatova
Authors: Mikhailova Galina
Published: November 2020

The article presents some considerations on the motives for the creation and text strategies of Akhmatova’s memories of Mandelstam. The Pages from a Diary are viewed from two points of view: first, as a fragment of Akhmatova‘s memoir prose of a certain historical time, as an actualization of personal memory in order to correct collective cultural memory; secondly, as a supertext formed by numerous drafts, lists and variations.Within the framework of this genre, it is possible to single out a number of principles that Akhmatova is guided by when creating a memoir text: for example, a dialogical mode of a “conversation” with existing memories, documents, oral evidence; intention of myth-fighting, etc. A look at the Pages from a Diary as a work of narrative prose (based on Akhmatova’s definition of memories as a “short story”), called “The Death’s Way,” allows us to add the hero of her memoir to a number of “damned poets” that are not alien to Mandelstam.
Primary Care Use and Assessment of Adolescents’ Sexual Health During Hospitalization
Authors: Clary Kathryn , Cortright Lindsay , Tumin Dmitry , Buckman Cierra , Eldridge David
Published: November 2020

OBJECTIVES:

Hospitalization provides an opportunity to address sexual health needs of adolescents who may not otherwise receive regular medical care. We investigated documentation of a sexual health discussion with adolescents hospitalized at our medical center to determine if previous primary care physician (PCP) visits in the same health system were associated with sexual health documentation during the hospital admission.

METHODS:

We retrospectively identified adolescents aged 13 to 17 years discharged from the pediatric general ward. Documented discussion of sexual health was reviewed in the electronic medical record. Previous PCP visits were identified from the affiliated primary care clinics within 12 months before hospitalization. We also queried follow-up PCP visits within 90 days of discharge to determine if a sexual health discussion during hospitalization was followed-up in the outpatient setting.

RESULTS:

We analyzed 394 patients (49% girls; median age 15 years), of whom 122 (31%) had documentation of a sexual health discussion while hospitalized and 75 (19%) had previous PCP visits in our health system. On multivariable analysis, older age (P < .001), female sex (P = .016), admission from the emergency department (P < .001), and a genitourinary primary problem at admission (P = .007), but not previous PCP visits, were associated with increased likelihood of sexual health documentation.

CONCLUSIONS:

Although discussion of sexual health was uncommon overall for hospitalized adolescents, we noted that nearly 4 in 5 adolescents for whom this was documented had not recently visited a PCP in our health system. These findings highlight hospitalization as a unique opportunity for sexual health intervention among adolescents who may not regularly see a PCP.

Published: November 2020

Dwarf suckermouth catfish are preferred especially for small aquariums. They are usually referred to as tank cleaners and commonly traded in the ornamental fish sector. Since these fish are nocturnal, it is difficult to observe their reproductive behavior and larval development. This study was carried out to determine the reproductive variables of bushymouth catfish (Ancistrus dolichopterus) under aquarium conditions. Three broodstocks bushymouth catfish with an average initial weight and a total length of 10.5±0.3 g and 9.5±0.2 cm were stocked in three 240-L aquariums with the ratio of 1:2 (male: female). The observations were made in triplicate tanks for six months. Females laid an average of 39.78±0.41 eggs and fertilization and hatching rates were 75.05% and 62.94%, respectively. It was found that the transition time from egg to apparently larval stage was 105.28 h, and bushymouth catfish showed an indistinguishable development from the hatching to juvenile stage without a real larval transition stage. The results of the study provide basic information on the reproductive performance and early development of bushymouth catfish.

Bu çalışmada, Türkiye'nin batı Akdeniz Bölgesi’nde yer alan; enerji, taşkın kontrolü ve sulama amacıyla kurulmuş olan, ayrıca balıkçılık ve turizm faaliyetleri için de yararlanılan Karacaören I Baraj Gölü’nü besleyen iki önemli kaynak olan Isparta Çayı ve Göksu Deresi’nin baraj gölüne karışım noktasında aşırı alg çoğalmaları (fitoplankton patlaması) incelenmiştir. Yoğun algal gelişim, ilkbahar başlarında Isparta Çayı ve Göksu Deresi’nin baraj gölüne karıştığı nehir ağzı bölgesinde kızıl-kahverengi belirgin bir bant olarak gözlemlenmiştir. Görsel olarak, alg patlaması yoğunluğunun nehir ağzı bölgesinden lakustrin bölgeye doğru azaldığı kaydedilmiştir. 18 Mart 2014’de bu ortamdan alınan plankton ve su örneklerinde plankton patlamasına neden olan organizmanın Dinoflagellata’dan Peridiniopsis cf. cunningtonii (Lemmermann) Lemmermann olduğu tespit edilmiştir. Bu türün en yüksek yoğunluğu Isparta Çayı ağzında 26.997; Göksu Deresi ağzında ise 22.262 hücre/ml olarak belirlenmiştir. Ayrıca alg patlamasının tespit edildiği sırada yoğun balık ölümleri gözlemlenmiştir. Bu sonuçlardan hareketle, özellikle Isparta Çayı’ndan gelen kentsel atıkların ve Göksu Çayı’ndan gelen balık yetiştiriciliği atıklarının baraj gölünde alg patlamalarını tetikleyebileceği ve bu durumun gelecekte de ortaya çıkabileceği öngörülmektedir.

Authors: YAZICI Ramazan , YAZICIOĞLU Okan , YILMAZ Mahmut
Published: November 2020

The relationships between dimensions of the asteriscus and lapillus and fish length for Wels catfish, collected from Sıddıklı Dam Lake between September 2015 and August 2016, are presented. No significant differences were noted between the dimensions of the left and right otoliths, and between otolith dimensions of male and female. For analyses, the right-side data of otoliths were used regardless of sex. The strongest correlation coefficient was obtained from the linear model for all relationships. Thus, a linear model was used for determining relationships. The r2 values of relationships between asteriscus dimensions and total length were more appropriate than relationships between lapillus dimensions and total length. Asteriscus height was more suitable than other otolith dimensions for predicting the length of Wels catfish. Results provided the first information on relationships between total length and otolith dimensions of Wels catfish. These relationships from this study can provide a reliable tool to reconstruct the predator diet, and to estimate the size of the prey, as well as also provide support to paleontologists in their research on fish fossils.

Self-directed Teacher Professional Development in Saudi Arabia: EFL Teachers’ Perceptions
Authors: Alshaikhi Hamad I.
Published: November 2020

This study explores Saudi EFL teachers’ perspectives, attitudes and experiences with regards to their teacher professional development (TPD) with special emphasis on workplace learning and self-directed initiatives. Using semi-structured interviews and reflective essays, the study managed to highlight a thriving workplace learning context in which teachers are involved in many forms of self-directed learning, including experiences stemming from the dailiness of the everyday realities of their schools. Data showed that Saudi EFL teachers are committed professionals who are well aware of a variety of TPD resources and opportunities; some of them are institutionalised while the majority are self-directed by teachers themselves beyond any institutional requirement. The study revealed that many participants had high preferences for self-directed learning over institutional provisions for its embeddedness in their context, the nature of their specialisation, and for the changing nature of their profession. Networking, collaboration, reflection and collegiality are some of the main features of self-directed learning as reflected in teachers’ current practices.
Learners’ Dialogical Interaction in the Service of Linguistic Knowledge Acquisition in Group Settings: Based on Contextual Factors
Authors: Wang Huanjie
Published: November 2020

This paper highlights some connections between dialogical interaction and knowledge acquisition in group settings. In learners’ quest to develop communicative competence and self-identity or social identity and acquire knowledge, dialogical interaction is applied to three contexts of knowledge-acquiring process where learners’ identity, learners’ mindset, learners’ rapport, learners’ communicative competence and learners’ knowledge are involved. Simply speaking, learners in collaborative contexts tend to share existing knowledge to generate potential knowledge; learners in competitive contexts are inclined to build knowledge, learners in cohesive contexts just use knowledge as a tool to organize knowledge. However, it is contended that dialogues are supposed to be explicitly regarded as part of the knowledge-acquiring process. There is a tendency to enable more effective knowledge acquisition through communicative talk, especially dialogues, in the interactive contexts with scaffoldings, tutoring or even intervention.
Ceridwen Dovey’s Only the Animals and the Politics of Re-interventions on Anthropocentrism
Authors: Rahaman Habibur
Published: November 2020

This article ascertains how Ceridwen Dovey’s Only the Animals (2014) aligns with interdisciplinary studies which critique anthropocentric binaries of human-nonhuman relationships. Drawing on a critical analysis of the selected stories of the book, this article attempts a broader study of Dovey’s book. Dovey’s ten stories are, as the article argues, a radical re-narrativisation against human-nonhuman binaries lying in the creative-cultural human world. It also sees the book as a subversive interrogation of human superiority. The ten animals of this book, then, are not mere metaphoric or symbolic embodiments of human sufferings, rather they represent an autonomous world of beings. These beings, as Dovey projects, challenge the human world’s cultural and creative ways of using and subjugating nonhuman beings to consolidate a human-centric world system. This article hinges on this aspect of the assertive nonhuman identity vis-à-vis the human identity, in particular, and then theoretically underpins Dovey’s book’s significance through some ecocritical  and post-human lenses.
An Analysis of Hurston’s Consistency with Her Original Aspiration and Mission in Seraph on the Suwanee
Authors: Yan Liping
Published: November 2020

Seraph on the Suwanee, Zora Neale Hurston’s last published long novel in 1948, depicting a white story, attracted almost no scholarly attention but much criticism for her pandering to white readers, betraying her previous characteristic themes in novel writing and abandoning her black cultural tradition and stance. This thesis aims to dig out the themes of the novel Seraph and the blackness behind the whiteness to find out that Seraph, in fact suffering wrong, tells a story by white faces with black voices, which demonstrates that Hurston continues her cultural stance and never changes her idea of not only employing black culture tradition but also insisting on her themes of writing as her previous novels.

Layered Motion of Two Immiscible Liquids with a Free Boundary
Authors: Lemeshkova Elena N.
Published: November 2020

The unidirectional motion of two viscous immiscible incompressible liquids in a flat channel is studied. An unsteady temperature gradient is set on the bottom solid wall, and the upper wall is a free boundary. Liquids contact on a flat interface. The motion is caused by the combined action of thermogravitational and thermocapillary forces and a given total unsteady flow rate in the layers. The corresponding initial boundary value problem is conjugate and inverse, since the pressure gradient along the channel is determined together with the velocity and temperature field. An exact stationary solution was found for it. In Laplace images, the solution of the non-stationary problem is found in the quadrature forms. It was established that if the temperature on the bottom wall and the flow rate stabilize with time, then the motion goes to a stationary state with time. This fact indicates the stability of the stationary solution with respect to unidirectional unsteady perturbations. The calculation results showing various methods of controlling motion by setting the temperature on the wall are given

On a Problem that Does not Have Basis Property of Root Vectors, Associated with a Perturbed Regular Operator of Multiple Differentiation
Authors: Imanbaev Nurlan S.
Published: November 2020

A spectral problem for a multiple differentiation operator with integral perturbation of boundary value conditions which are regular but not strongly regular is considered in the paper. The feature of the problem is the absence of the basis property of the system of root vectors. A characteristic determinant of the spectral problem is constructed. It is shown that absence of the basis property of the system of root functions of the problem is unstable with respect to the integral perturbation of the boundary value condition
On the Equationally Artinian Groups
Authors: Shahryari Mohammad , Tayyebi Javad
Published: November 2020

In this article, we study the property of being equationally Artinian in groups. We define the radical topology corresponding to such groups and investigate the structure of irreducible closed sets of these topologies. We prove that a finite extension of an equationally Artinian group is again equationally Artinian. We also show that a quotient of an equationally Artinian group of the form G[t] by a normal subgroup which is a finite union of radicals, is again equationally Artnian. A necessary and sufficient condition for an Abelian group to be equationally Artinian will be given as the last result. This will provide a large class of examples of equationally Artinian groups
Finite Difference Schemes for Modelling the Propagation of Axisymmetric Elastic Longitudinal Waves
Authors: Sadovskii Vladimir M. , Efimov Oxana V. , Efimov Evgenii A.
Published: November 2020

An efficient finite difference shock-capturing scheme for the solution of direct seismic problems is constructed. Problem formulation is based on equations of the dynamics of elastic medium with axial symmetry. When implementating the scheme on multiprocessor computing systems, the two-cyclic splitting method with respect to spatial variables is used. One-dimensional systems of equations that arise in the context of splitting procedure are represented as subsystems for longitudinal, transverse and torsional waves. The case of longitudinal waves is considered in this paper. The results of simulations with the use of explicit grid-characteristic schemes and implicit schemes of the "predictor–corrector" type with controllable dissipation of energy are compared with exact solutions that describe propagation of monochromatic waves

Application of linear discriminant analysis for classification of electrical grid emergency states
Authors: Kulikov A.L. , Bezdushnii D.I. , Osokin V.Y.
Published: November 2020

The approach of development of relay protection algorithms based on statistical data analysis suggests a transition from traditional protections to innovative multidimensional algorithms of recognition which are able to use the available information for emergency states identification more efficiently. The state parameters used for recognition are usually combined into a single multidimensional space. This results in computational complexity of the recognition algorithm. Thus, it is advisable to implement relay protection algorithms based on generalized features. This decision will make it possible to decrease the dimension of the feature space and increase response time of the protection. The linear discriminant analysis is used to reduce the feature space dimension when recognizing the states of an electrical grid section. The training sampling for statistical analysis is formed using a simulation model of the analyzed network section. The error matrix obtained as a result of the application of k-nearest neighbors algorithm for the state classification in the developed feature space was taken as a criterion for the feature space efficiency. A method of feature space dimension reduction for the task of multidimensional relay protection was proposed. It involves generalized features of response obtained via linear discriminant analysis. The method allowed formation of a setting plane which is the most effective for different types of short-circuit classification. This setting plane provides an error-free state classification while the setting planes obtained by pairs of initial features demonstrate an error of up to 50 %. The set goal of the feature space dimension reduction was achieved. Linear discriminant analysis is advisable to use by relay protection manufacturers for reduction of the feature space dimension in multidimensional relay protection problems, including multiple classification problems.
Computational and experimental study of classification of a mixture of dissimilar components
Authors: Barochkin A.Ye. , Belyakov A.N. , Otwinowski H. , Wylecial T. , Barochkin E.V.
Published: November 2020

The classification of particles by size is traditionally considered in relation to homogeneous materials, which must be divided into coarse and fine products. However, often there are the impurities in the material that differ in their physical properties from the base component. When classifying such mixtures, the difference in physical properties can be used to isolate, purify, or enrich the main component. The choice of the technology for such processing dissimilar components is possible based on simple and adequate models. The formulation and solution of classification problems for mixtures of dissimilar components on the basis of adequate models is the relevant issue for the power industry and related industries. Fundamental laws of dispersed systems dynamics are used to simulate the classification process; mathematical programming methods are used to identify models and improve separation technology. Experimental study of the separation of a mixture of dissimilar components in a two-stage classifying system has been carried out. Using the obtained experimental data, the model was identified, and its adequacy was shown. The presented experimental results and computational model can be used to formulate and solve optimization problems of fractionation of dispersed materials and to increase the efficiency of the process in classifying systems. The results obtained can be used in the energy, chemical and other industries to improve the efficiency of resource and energy-saving technologies for obtaining dispersed products with acceptable content of impurities.

Published: November 2020

The location of the Fenced Lagoon in the urban basin of Bandar Anzali, which should be considered due to its impact on the lives of the people of the region in terms of the conservation of the wetland and its environmental issues, and, on the other hand, the potential of this area to be introduced as a geotourism center determine the need to investigate the area's sedimentology and geochemistry. Therefore, to study sedimentary and geochemical properties of the Fenced Lagoon sediments located in Bandar Anzali, 33 samples were taken in the form of 6 cores and 12 grabs, andbasic sedimentation tests and heavy metals measurement were carried out through XRF. Studies show that the sediments are ranged from sand to clay in terms of gradation and have mainly costal-river origin. The sediments of this lake are classified into four sedimentary types: Muddy Sand, Slightly Gravely Muddy Sand, Sand and Slightly Gravely Sand and sand is the main component of all of these sediments. The most abundant sedimentary types belong to Muddy Sand and Sand and the least abundant sedimentary types belong to Slightly Gravely Muddy Sand and Slightly Gravely Sand. The nature of the source rock is derived from acidic to intermediate combination and in general, sedimentary rocks of the area under study are within the continental arch islands and, to a lesser extent, the active continental margin.

The article discusses the Swedish ethnopolicy in relation to Sami people in language and educational spheres, its influence on national and local indigenous languages usage, the evolution of this policy during the last decades of XIX and XX centuries and the state of the modern educational situation.

The author examine the dynamics of the Swedish Kingdom’s language-educational policy development, causes, and aftereffects of governmental institutions; Swedish and Sami organizations and single activists actions, which influenced the indigenous public educational system. The attention is concentrated on the main action aspects of this sphere with the determination of positive and negative consequences. Moreover, the conducted study identified the main reasons of language-educational changes from the side of governmental administrative institutions and Swedish Lutheran Church, which happened under the influence of internal (the northern lands colonization, governmental fears about Sami hypothetical possibilities of attraction to separatist activism, Sami cultural development factitious leaving) and external (the development of European-wide and world ideas, theories and mainstreams – Social Darwinism, Nazism, Liberalism, etc.) factors. The author describes the educational process in a special form of «kota-schools», which were adapted to Sami nomadic lifestyle, but at that time they were assimilation instrument for the indigenous people. Also, the research explains the main causes of the educational system downfall. The article highlights the «reconciliation» process between the Lutheran Church and Sami people, where the introduction of Sami language and its dialects in church liturgy and religious literature publishing stimulated the process. The study presents information about law basement evolution, which provided and regulated the usage of Sami language in different spheres of life.
Recourse action against investigative authorities is a legal way of «fall guys:» identifying who made a mistake in the criminal procedural system
Authors: Kovtun Kovtun N.
Published: November 2020

The author indicates how and in which ways tendencies of recourse recovery from guilty persons of investigative authorities can be realized. The article reviews practical experience of recourse actions disposition over the last years in the Russian Federation. From the authors point of view, this practical experience is confusing, conflicting, and potentially hazardous.

In 2018, the Law Commission of the Government of the Russian Federation endorsed a bill aimed at improving recourse actions against investigative authorities. The legal fundamentals of the bill are stated in regulations of Chapter 18 the RF CPC and again in Articles 1069, 1070, 1080, sub-paragraphs 3 and 3.1 of the Article 1081 of the CCRF. The main idea of the bill is to improve the subjects and practice of recourse recovery from guilty parties of investigative authorities and other law enforcement agencies of those funds that were disbursed to rehabilitees from the Treasury of the Russian Federation account in accordance with Chapter 18 of the RF CPC [1]. The Russian Federation State Duma presented a bill in 2019 that specified the minimum amount of state monetary compensation for unwarranted prosecution of such persons who (in future) would be liable to rehabilitation. There are some innovations of the given bill. The minimum compensation per rehabilitee is 1000 RUB for each day of pretrial investigation and judicial inquiry; 5000 RUB per day for illegal use of such restrictive measures as house imprisonment, restraining order, and written undertaking not to leave the place; and 15 000 RUB per day of illegal stay in pretrial detention facility [2].

If these new measures are accepted, the amounts of recourse against investigative authorities will be cardinally increased. The keys of the above-noted lie in growing statements. The main point of these statements is that the federal budget loses huge sums annually and irrevocably through the realization of institute rehabilitation.

Indian Economy is one of the fastest growing economies in the world, currently growing at around 7%. However, India’s growth has been highly uneven and lop-sided. Sectors such as services relying on exports have grown far more whereas manufacturing and agriculture have languished. As global trade environment becomes tougher, there is increasing realization that India’s domestic economy needs to grow lot more. In this context, balanced growth theory proposed by Ragnar Nurkse and many other Economists in 1950s is worth revisiting. Nurkse called for unleashing growth across different sectors of domestic economy simultaneously. Nurkse identified productivity as key determinant of market size and considered the poor as participants in the growth process than as mere beneficiaries. Even though balanced growth model is an ideal to aspire for, there are very few success stories which laid a clear roadmap to achieve it. Further, we need to reimagine the balanced growth model for today’s context to take into consideration newer challenges and opportunities compared to 1950s. In addition, the role of the Government needs to be recalibrated to be a catalyst in market economy in contrast to planned economies. To accomplish this complex task, we need an information framework that has an ecosystem approach and looks at society holistically. We propose the use of Ontology-based Tantra Social Information Management Framework to steer India towards the balanced growth ideal. This paper contains the description of Tantra Framework and our approach to realize balanced growth using Tantra Framework.

Published: November 2020

The aim of this study is to assess the spatial variability and to determine the main contamination sources in surface water quality of the Nhue River, Viet Nam by using multivariate statistical analysis techniques, including principal component analysis (PCA) and cluster analysis (CA). Eight water quality parameters were measured at 21 sites along the Nhue River and its tributaries during irrigated periods from 2016 to 2019. The spatial variability of water quality in the Nhue River and its tributaries was determined separately from cluster analysis. The result determined two tributaries, including Yen Xa Canal (NT9 monitoring site) and To Lich River (NT3 monitoring site) leading to severe pollution at To Bridge (N4 monitoring site) region in the Nhue River. The PCA determined a reduced number of two principal components that explained 47.75% of the total variation in the data. The first PC indicated that water temperature (WT) and pH are the dominant polluting factors which are attributed to craft villages, domestic sewage and industrial wastewater. Following is nitrate nitrogen NO3¯ in the second PC which is related to fertilizer application in the farms nearby. The results indicated that CA multivariate statistical analysis technique is useful for the assessment of the spatial water quality variability in a river which has a number of tributaries.

Authors: Nagraj Devina , Yi Ching Ling , Dalal Asha R.
Published: November 2020

Background: Traditionally women undergoing lower segment caesarean section (LSCS) had oral food withheld for12-24 hours to prevent gastrointestinal complications. However, it was observed in many studies, that early oral feeding to patients post LSCS improves recovery and decreases chances of post-operative complications.Methods: This was a randomized interventional study conducted in a public hospital. Uncomplicated patients who underwent LSCS under regional anesthesia were selected. Group A and B with 100 participants each were made. One group (A) was given early orals (6 hours) and other group (B) was given orals after 12 hours.Results: The early feeding group had earlier return of bowel movements and earlier passage of flatus (8 and 13 hours) as opposed to delayed feeding group (10 and 18 hours). 13% patients in the early feeding group had complications as opposed to 43% patients in the delayed feeding group. The most common complication was abdominal distension which was seen in 5 and 10 patients of the early and delayed feeding group respectively.Conclusions: Early oral feeding after LSCS can lead to early recovery, better mother and child health, better utilization of the hospital resources and decreased financial burden on the family as well as the government in the long run.

Background: Tobacco use is the single, largest preventable cause of death and disability worldwide. Area-specific community-based epidemiological studies on tobacco use are required to quantify the problem, identify the determinants and their distribution. The objectives were to find out the prevalence, patterns and socio-demographic correlates of tobacco use in Davangere taluka, Karnataka, India.Methods: This was a community-based, cross-sectional study of 2008 subjects (>10 years of age) in urban and rural areas of Davangere taluka, Karnataka. Interviews were conducted by using a structured, pre-tested questionnaire by house-house visits.  Results are presented using percentages, chi-square test, odds ratio and multiple logistic regression analysis.Results: The prevalence of tobacco use was 30.7%. Among urban males it was 39.5%, rural males 39.6%, rural females 26% and urban females 18.5%. Tobacco use was significantly associated with sex, locality, religion, caste, marital status, family type, occupation, and tobacco use in family or friends. There was direct relationship of tobacco use with age and inverse relationship with education and socio-economic status. Mixed tobacco use was higher in rural areas compared to urban areas. About 73.9% of 10-29 years persons had started before the age of 18 years. Among older participants there was higher frequency of consumption and duration of use.Conclusions: Tobacco use is common and it is influenced by various local socio-demographic factors. Addressing these factors and providing tobacco cessation services should be included as key strategies in tobacco control.

Authors: Kalbani Bushra Hamdan Al , Singh Amar , Sheibani Salma Mohd Al
Published: November 2020

Lemierre disease (LD) is a rare but potentially life-threatening condition, characterized internal jugular vein suppurative thrombophlebitis and disseminated septic emboli following a recent oropharyngeal infection. It is seen commonly in healthy young adolescents or adults, caused by gram negative anerobic Fusoform necropharum. Lack of awareness of this condition delays treatment and worsens prognosis. We present two interesting cases of LD in diabetic patients, caused by Klebsiella pneumonia and Haemophilus influenza organisms at our hospital. Both patients had atypical presentations. Diagnosis of such atypical cases poses diagnostic and therapeutic challenges.

The Special Efforts Program (Upsus) is an Indonesian government program to increase production/productivity of lowland rice to support the realization of food self-sufficiency. The Upsus targets are to increase the planting index by 0.5 and productivity by 0.3 tons/ha/GKP. The increase in planting index is achieved by the expansion of added planting, but the increase in productivity has not been reached optimally due to pest and disease attacks. The objective of this research was to determine the knowledge, attitudes, and actions of Upsus farmers in controlling pests and diseases, rice cultivation techniques, and implementation of Upsus in Karawang District. The research was conducted by distributing questionnaires to 60 farmers in Tempuran and Tirtajaya Sub-District at Karawang District. The respondents were selected by purposive sampling with the consideration of respondent being an active farmer, having at least 5 years of farming experience, and has ben a member of Upsus for at least 1 year. Most respondents have age in the range of 41-60 years, the highest education of elementary school, and have farming experience for 5-10 years. Pests and diseases are the biggest problems faced by the farmers. Upsus farmers used Ciherang and Inpari 32 varieties and the applications of pesticides were conducted according to the schedule. Most of the farmers could not distinguish between pests and diseases. The dominant pest and disease control carried out was the use of chemical pesticides.
