Embryological, anatomical and clinical considerations on pleuroperitoneal communication
Authors: Chatzigrigoriadis Christodoulos , Goulioumis Anastasios , Sperdouli Despoina , Gyftopoulos Kostis
Published: June 2023

The pleural and peritoneal cavity share many related features due to their common celomic origin. Normally these two spaces are completely separated with the development of the diaphragm. Defects in diaphragm morphogenesis may result in congenital diaphragmatic hernias, which is the most known form of communication between the pleural and peritoneal cavity. However, in several cases, findings of pleuroperitoneal communication (PPC) have been described in adults through an apparently intact diaphragm. In this comprehensive review we systematically evaluate clinical scenarios of this form of “unexpected” PPC as reported in the literature and focus on the possible mechanisms involved.

Authors: Jahan Bushrat
Published: June 2023

Bangladesh is a South Asian country having become independentrecently and confronting countless crimes, and transnational coordinated crimeis one of them. With the proliferation of criminal associations and theaccessibility of present-day digitalization, the level of transnational danger hasincreased in an alarming way, where just a coordinated and elevated degree ofglobally approved cooperation can resolve the issue. Transnational organizedcrime increases border tensions and danger also. In this paper, I will focus on afew explicit transnational crimes occurring in Bangladesh and how those canbe a future danger to the existence of this country. Border hostility, armsdealing, drug trafficking, and illegal human exploitation have been persistentsecurity dangers to the country. I will likewise concentrate on some combatingmeasures taken by the EU to control transnational organized crimes and acomparative discussion of how Bangladesh ought to step up measures tocontrol such crimes in the future.

Published: June 2023

Creating climate-neutral electronic communications is a sharedresponsibility for the industry and urgent action is needed in the face ofwarming trends due to global climate change. Despite this, environmentalsustainability has just started to receive attention in the regulation of theelectronic communications sector. The national telecoms regulatory authoritiesoverseeing the sector in the different countries are key in driving related policyand regulation. However, as to date, hardly any paper has dealt with theirrespective practices in a comparative manner. Therefore, the aim of this paperis to fill this gap, to review the relevant environmental sustainability regulatoryand policy practices and actions of telecoms regulatory authorities, in order toprovide a comprehensive and high-level comparison of sustainability initiativesin the electronic communications sector. It is hoped that this will serve as astarting point for launching a discourse in the industry and for properlypositioning the green transition in electronic communications regulation.
Comparative Legal and Economic Analysis of Franchising
Authors: Namsrai Battulga
Published: June 2023

Franchising is a business model that has been converting dozens ofintangible assets into tangible in the history of mankind. Thus, nowadays it byitself covers a wide range of institutional aspects of law and economics.Besides, a franchise runs according to Nash’s Equilibrium theory. A player canachieve the desired outcome by not deviating from their initial strategy. For thispurpose, the franchisor provides an amount of assistance to the franchisee instarting and managing the business activities.De facto, principles of equality are slightly different for franchise contracts.This is because the results of the contract cannot be achieved without the strictsupervision and advice of the license holder.Therefore, this short comparative research has considered legal and businessissues relating to franchise, including the main contract law requirements, thedisclosure obligation, patent protection, vertical restraints, and the generaleconomic outcome of franchising in some countries.
A review of online business regulatory framework to reduce IFF in Bangladesh
Authors: Sony M M ABDULLAH AL MAMUN
Published: June 2023

Illicit Financial Flow (IFF) is a key development challenge all over the world.

In developing countries, though IFF may take place in differentways, but over the past couple of years IFF via the digital ecosystem has beendemanding a rethink of the existing legal structure.

For instance, in Bangladesh, the fastest developing country, by today about five

leading ecommerce companies have been accused of fraud mostly in supply chainmanagement and also accused of money laundering issues. Therefore, theBangladesh government has adopted Digital Commerce Guidelines. Since thesee-commerce scams take place frequently, this raises the question of theeffectiveness of this existing legal structure in Bangladesh and how the samelegal framework can meet the challenge of IFF via digital platform. With thehelp of the comparative method, the research has tried to address these gaps inacademic literature from a qualitative approach. This study has indicated that aflaw in Bangladesh's present regulatory system is the lack of legislativedirections on how to supervise excessive discounts or predatory pricing.Finally, no cross-border e-commerce rules or recommendations have beenestablished under the present legal regulatory framework. As a result, it issuggested that these flaws in the current policy be reconsidered to reduce IFF.Overall, the findings of this study will assist policymakers in defining additionalactions aimed at reforming a robust digital regulatory environment.

The renaissance of compulsory licenses (in the pharma sector)
Authors: Szupera Blanka
Published: June 2023

This paper examines the function of compulsory licensing of themanufacture of pharmaceutical products. The COVID-19 pandemic haschallenged the pharmaceutical patents and the compulsory licenses in thepharmaceutical sector. In International law the TRIPS Agreement introduced aspecial possibility to use the subject matter of a patent without the authorizationof the right holder. The development of this license was determined by thepublic health problems of the least-developed countries (hereinafter referred toas the LDCs). Today the global pandemic has challenged this system. Somedeveloping countries proposed that the World Trade Organization temporarilyshall waive intellectual property rights for COVID-19 vaccines. The legislationof some countries allowed the governance to order the limitations of patents,but such a solution could harm the legitimate interests of the patent owners. Theglobal need for rapid treatment of COVID-19 showed that patentees cannotmake pharmaceutical inventions sufficiently available on the market. There areother solutions like patent pools, by which patent owners could keep control ofthe use of their inventions and the patents would be still available for thirdparties. This would serve the general public interest, but it is a money and timeconsuming, long-distance cooperation. The broadened use of compulsorylicensing could also expand vaccine manufacturing within the patent system.Hungary has chosen this path and the new legislation means the renaissance ofcompulsory licenses.

Published: June 2023

In situ sensors that are used to detect the pavement response play an important role in the health monitoring of asphalt pavement. However, embedded sensors have both the positive benefits of pavement condition monitoring and the negative effects of structural-performance degradation, especially for sensors with improper external shapes or profiles. The stress and strain field variations and sensor interaction with damage should be included in the structural optimization problem. In this article, the effect of sensor embedding on the stress and strain field variations was analyzed through numerical studies on an asphalt concrete specimen under three-point bending configuration. Three-dimensional finite element models of sensors with different shapes (I-shaped sensor and bamboo-shaped sensor) were developed using ABAQUS to compare the dynamic response under cyclic loading. The analysis results indicated that the embedment of a bamboo-shaped sensor caused greater mechanical response and enhanced stress concentration at the position where the sensor was embedded. In particular, the embedment of two types of sensors had little influence on the stress and strain field inside the asphalt concrete beam within the depth range of 0–60 mm, but different degrees of influence were produced within the depth range of 60–100 mm (tension zone). The results of axial stress and strain indicated that the deformation of I-shaped sensor was more uniform and coordinated with that of asphalt concrete. Afterward, the excellent compatibility and deformation coordination between the I-shaped sensor and asphalt concrete was confirmed by three-point bending tests and further applied to real pavement structure to monitor traffic loads. It can be concluded that the material and structural compatibility of I-shaped sensor are superior to that of bamboo-shaped sensor as a pavement sensor, and the dynamic response obtained by the I-shaped sensor is closer to the true value. The study results provided an optimization structure for design reference of embedded sensors for pavement structural health monitoring.
Influence of acid concentration, temperature, and time on decrystallization in two-stage concentrated sulfuric acid hydrolysis of pinewood and aspenwood: A statistical approach
Authors: Janga Kando K. , Hägg May-Britt , Moe Størker T.
Published: June 2023

The effects on sugar yields of acid concentration, temperature, and time in the first (decrystallization) stage of a two-stage concentrated sulfuric acid hydrolysis of softwood (Scots pine) and hardwood (aspen) were investigated. The study focused on the multi-variable effects of the decrystallization stage and applied a statistical modeling with Central Composite Face (CCF) design of experiment to systematically study and simulate the effect of decrystallization reaction conditions on hydrolysis products and degradation products. The models were statistically significant and showed that for both aspen and pine, the reaction temperature and acid concentration were the most influential variables on monosaccharides and total sugar yields compared to the reaction time. The interaction between temperature and acid concentration was the most important for both species. The sugar degradation products were much influenced by the decrystallization temperature on both aspen and pine. The models were validated by a test-set and showed a good agreement between the experimental and predicted values. The optimum predicted total sugar yields were 56 g / 100 g d.w for aspen (74% theoretical) and 64 g / 100 g d.w for pine (91% theoretical).

Authors: Liu Chengguo , Yang Xiaohui , Cui Jingfang , Zhou Yonghong , Hu Lihong , Zhang Meng , Liu Hongjun
Published: June 2023

A tung oil (TO) based monomer for rigid thermosetting polymer was synthesized, characterized, and copolymerized with styrene in this study. Tung oil was alcoholyzed with pentaerythritol (PER) to get tung oil pentaerythritol alcoholysis products (TOPER), and the optimized conditions were explored according to the yields of TOPER analyzed by gas chromatography-mass spectrometry (GC-MS). The resulting alcoholysis products were maleinated to form tung oil maleate half ester (TOPERMA), and the reaction conditions were determined by monitoring the reaction extents of TOPER and maleic anhydride (MA) with 1HNMR spectroscopy. The TO alcoholysis and maleinization reaction products were characterized by IR, 1HNMR, and electrospray ionization-mass spectrometry (ESI-MS) techniques. At last, the TOPERMA mixture was cured with styrene (St), and the initiator tert-butyl peroxy benzoate (TPB). Differential scanning calorimetry (DSC) was employed to characterize the curing process. Mechanical properties of the cured TOPERMA/St resin further confirmed the best procedure for the maleinization reaction. The loading of TO reached about 30% weight of the resulting thermosetting polymer. This promising material from renewable resources can be a potential substitution for petroleum products when used as sheet molding compounds.

Authors: Chaiarrekij Somporn , Apirakchaiskul Apiporn , Suvarnakich Kuntinee , Kiatkamjornwong Suda
Published: June 2023

The potential use of kapok fiber for pulping and papermaking has been investigated. The kapok fibers were cooked using the optimal dosage of sodium hydroxide determined from the experiments. Then, the pulp was refined with two passes using a disc refiner and mixed with commercial hardwood pulp and/or softwood pulp at different blend ratios to make papers. It was found that addition of the kapok pulp to the mixed pulps improved the tensile and burst strengths of the sheets but decreased the tear resistance and elongation. Water repellency of the sheets prepared from the kapok pulp mixed with the commercial pulps was also improved. These results indicate that kapok fiber can be a quality pulp source for papermaking, especially for packaging paper requiring strength and water repellency.

Published: June 2023

This research provides an optimal design of structural parameters for ring-die granulators used in the cool briquetting process. Experimental research on the briquetting rate of pellets was carried out for three kinds of crop straws with different granularities, moisture ratios, and length-diameter ratios of the die hole. Results showed that: when the swoop angle β was 45o and the diameter ratio of roller to die was equal to 0.585, the equipment would have higher productivity and lower die-roller contact strength, yielding a good comprehensive briquetting effect; when the granularity was 4mm, the moisture ratio was 16% and the length-diameter ratio was 5.2, the equipment would ensure a higher briquetting rate of pellets and the lowest power consumption per ton of material, yielding the best briquetting effect. This provides references for structural design and process parameters selection of ring-die granulators.
Dimensional stability of methyl methacrylate hardened hybrid poplar wood
Authors: Ding Wei-Dan , Koubaa Ahmed. , Chaala Abdelkader
Published: June 2023

This study examines the dimensional stability of fast-growing poplar clones wood after treatment by impregnation with methyl methacrylate (MMA). Six hybrid poplar clones from one plantation in Quebec were sampled. The effects of hardening with MMA on density as well as longitudinal, radial, tangential, and volumetric swelling properties (S), water uptake capacity (D), anti-swelling efficiency (ASE), and water repellent efficiency (WRE) after soaking were investigated. Hardening treatment increased the density of all poplar woods by 1.2 to 1.6 and decreased the inner water migration rate during soaking. S and D values of hardened woods were significantly lower than those of controls, depending on the clone type. ASE and WRE values suggested that incorporating MMA effectively improved the dimensional stability of poplar wood at the early soaking stage, but was less effective in the long term.
Preparation and characteristics of a paper-based ultrafiltration membrane
Authors: Wang Jian , Zhou Xiaofan , Ma Jinxia
Published: June 2023

A novel process involving a paper-based ultrafiltration (UF) membrane was developed via paper coating technology. The membrane employed a paper sheet as support layer and a coated thin film layer of adhesive. The proper selection of paper sheet support layer was crucial to the performance of the ultrafiltration membrane. A paper sheet with beating degree of 85oSR and basis weight of 50g/m2 was chosen as the support. PVA was chosen as the adhesive. The paper-based ultrafiltration membrane achieved high retention performance while using a simple production process and keeping the production cost low. Disadvantages of the membrane included low porosity and low pure water flux. So further investigation is still needed to produce a fully satisfactory paper-based ultrafiltration membrane.

Published: June 2023

Organosolv pretreatment was applied to Chinese using the acid-catalysis ethanol method to enhance sugar recovery in enzymatic hydrolysis. A Box-Behnken design (BBD) was used to optimize the effect of temperature, ratio of wood to liquor, ethanol concentration, and holding time on the pretreatment process. All variables except for lignin content were found to significantly affect the cellulosic yield as well as crystallinity index (CrI). Quadratic polynomial equations were used to model on the cellulosic yield, CrI, and lignin content for a regression analysis, using response surface methodology (RSM). The optimum process of organosolv pretreatment of Chinese was found to be: temperature: 185 ºC, ratio of wood to liquor: 1 to 4.2, ethanol concentration: 45%, and holding time: 41 min. The solid pretreated under optimum process conditions was evaluated for bioconversion using enzymatic hydrolysis of the cellulose fraction to glucose. Approximately 87% of the total cellulose in the poplar was recovered as monomeric glucose after hydrolysis of the solid fraction.
The removal of Reactive Red 228 dye from aqueous solutions by chitosan-modified flax shive
Authors: Feng Hao , Li Jian , Wang Lijuan
Published: June 2023

Flax shive (FS) is a byproduct from flax fiber separation. The use of absorbent prepared from chitosan-modified flax shive (CFS) has been studied for removal of reactive red dye (RR228) from aqueous solutions. CFS was characterized by the Brunauer-Emmett-Teller (BET) method, Scanning Electron Microscopy (SEM), Fourier Transform Infrared spectrometry (FTIR), and X-ray photoelectron spectroscopy (XPS). A batch adsorption study was conducted under various contact time, initial concentration, solution pH, and adsorbent dosage. It was found that the BET and Langmuir surface area of CFS were 1.772 m2 g-1 and 3.057 m2 g-1, respectively. Results showed that CFS has the same pores as FS and that the –NH2 group on CFS is the main adsorption site for dye sorption. Equilibrium adsorption capacity could be reached within 480 min, and RR228 uptake was satisfactory at a pH of 2.0. The percentage removal were 100%, 100%, 90%, and 85% at pH 2.0 under dye concentrations of 10 mg/L, 20 mg/L, 30 mg/L, and 40 mg/L, respectively. The adsorption accurately fitted a pseudo-second-order kinetic model and a Langmuir isotherm model. It is proposed that CFS could be applied as a low-cost absorbent in removal of dyes from wastewater.

Published: June 2023

Commercial bamboo chips were evaluated as raw material for dissolving pulp production. The chips were auto-hydrolyzed (AH) and subsequently cooked by the NaOH/AQ process and bleached to full brightness with the O-CCE-D-(EP)-D-P sequence. The term CCE designates a cold caustic extraction stage. The bamboo chip chemistry (22.4% lignin, 19.5% xylans, 49.3% cellulose, 16.8% total extractives, and 1.5% ash) was apparently unfavorable; however high quality dissolving pulp was produced using the aforementioned technologies, even when compared to results obtained with traditional eucalypt commercial wood chips. The pulp showed high brightness (92.4 % ISO) and α-cellulose content (94.9%). Its contents of hemicelluloses, extractives and ash were within acceptable levels for a dissolving pulp aimed at viscose rayon production. Thus, the bamboo chip furnish investigated can be regarded as a viable raw material for dissolving pulp production.
A wood replacement material of sandwich structure using coir fiber mats and fiberglass fabrics as core layer
Authors: Yao Jia , Hu Yingcheng , Lu Wei
Published: June 2023

The tensile strength and bending strength of natural coir fiber are lower than many other natural fibers. Therefore, coir fiber is unsuitable for many fiber reinforcement applications. This study exploits the better shock resistance and toughness of coir fiber, which suggest that coir fiber can be used as a type of replacement material in plywood. Fast-growing poplar was chosen as the surface material, and coir fiber was selected as the core layer material for their buffering ability and toughness, and fiberglass fabrics were added in the core layer as strengthening components. The optimization of this plywood structure was carried out with an orthogonal experiment and the intuitive analysis method. The mechanical performance of some samples even exceeded that of natural wood. Through analysis of test results and scanning electron microscope (SEM) observations, the buffering and toughening mechanisms of the coir fiber mats were revealed. This new material can be used to replace wood in plywood and in the transportation industry as a packaging material and as platform floors for freight vehicles.
Decay resistance and physical properties of oil heat treated aspen wood
Authors: Bazyar Behzad
Published: June 2023

The decay resistance of oil-heat treated aspen wood (Populus tremula l.) against white rot fungi (Coriolus versicolor) and brown rot fungi (Coniophora puteana) was investigated. Three different temperature stages and two time levels for oil heat treatment for the selection of optimum conditions were determined. Linseed oil as a heating medium was used. The mass loss of treated samples that were exposed to both fungi was significantly lower than that of the control samples. Results also showed improvement in dimensional stability after oil heat treatment. Decay resistance and dimensional stability of aspen wood were increased significantly with temperature increasing, but time seemed to have no effect on those properties. Oil heat treatment is a suitable method to improve decay resistance of aspen wood as it reduced the mass loss by 71% and 77% against Coriolus versicolor and Coniophora puteana compared with control samples, respectively. On the other hand, oil heat treatment improved the dimensional stability by about 20.5%.

Published: June 2023

The biochemical properties of a purified enzyme of a new alkalophillic endo-1,4-beta-xylanase gene, KRICT PX2 (GU967374), which was isolated from Paenibacillus sp. HPL-002 (KCTC11410BP) and expressed in E. coli, were investigated. The specific activity of the purified xylanase was 51.26 μmol/min/mg proteins. The Km and Vmax values of the protein for birch wood xylan were also verified to have 0.061 μM and 55.3 μmol/min/mg proteins, respectively. The optimum pH and temperature for the activity of the enzyme were pH 8~9 and 50oC, respectively, and, the activity was stably maintained at 40oC. Most metallic salts, ethylenediamine tetra-acetic acid, 2-mercaptoethanol, phenylmethane-sulphonyl fluoride, and furfural, have no impact on the enzyme’s activity at 1 mM. The simulated 3-D structure of this xylanase is similar to Xyn10B from Paenibacillus barcinonensis. Further research on the degradation of different-origin xylans and enzyme production will be necessary for practical applications.
Nitrogen fixation and chelating property of wheat ammonium sulfite pulping spent liquor
Authors: Wang Zhe , Xue Jingwen , Liu Wenxia
Published: June 2023

Nitrogen fixation of wheat straw ammonium sulfite pulping spent liquor and the chelating property of nitrogen-fixed ammonium lignosulfonate were studied. Results showed that free ammonium nitrogen in spent liquor could be fixed by formaldehyde. When the amount of formaldehyde was 10% based on the dry weight of lignosulfonate, 30% of inorganic nitrogen was converted into organic nitrogen, of which 87.4% was ammonium lignosulfonate and 12.6% was urotropine. The proper chelating condition of nitrogen-fixed ammonium lignosulfonate was as follows: pH:3, hydrogen peroxide:10%, FeSO4: 40.9%, and 50 oC for 30 min. Under this reaction condition, the chelating ratio of Fe2+ was measured as 15.1%. Chelation did not result in Fe(OH)3 precipitation under alkaline conditions. Effects of H2O2 dosage on the structure of ammonium lignosulfonate were also studied. The content of carboxyl, phenolic hydroxyl, and conjugated carbonyl groups in lignosulfonate that could be chelated with metal ions increased after ammonium lignosulfonate was oxidized. Average molecular weight and distribution were also determined with GPC. Results showed that the proportion of higher molecular weight components increased after oxidation of ammonium lignosulfonate, indicating that oxidative degradation and condensation reaction proceeded during oxidative treatment and condensation was the main reaction. The increase of molecular weight could improve the chelating ability of ammonium lignosulfonate.

Published: June 2023

Este artigo é resultado de uma pesquisa de doutorado, em desenvolvimento, que teve como objetivo identificar o que as produções científicas nacionais recentes apresentam sobre o desenvolvimento da linguagem oral das crianças. A metodologia constituiu-se de revisão sistemática integrativa com buscas nas bases de dados eletrônicos da Biblioteca Digital Brasileira de Teses e Dissertações (BDTD) e no catálogo de teses e dissertações da CAPES, para publicações entre o período de 2012 e 2022. Os acessos às bases de dados aconteceram entre 18/05/2022 até 16/08/2022. Para a sistematização dos trabalhos encontrados foi utilizado o fluxograma recomendado pelo grupo PRISMA. As estratégias de buscas resultaram em quatorze produções científicas, das quais se dedicaram a pesquisar a prática pedagógica dos professores, o  desenvolvimento da linguagem oral das crianças com foco na oralidade e escrita, as interações entre professores e as crianças, e as interações promovidas por atividades desencadeadoras, como é o caso dos livros de literaturas, e o planejamento, avaliação e registros. Concluímos que as produções científicas encontradas tiveram como tema central a linguagem oral, mas quando se trata de pesquisas que envolvam as interações linguísticas que ocorrem entre professores e crianças bem pequenas da Educação Infantil, e que têm o trabalho pedagógico comprometido com o desenvolvimento da linguagem oral das crianças, o número de pesquisas são escassas. Isso nos revela que ainda há uma série de questões a serem investigadas sobre essa temática, que ainda se apresenta muito incipiente em nosso país.

Methodology: A review about MSAs designed for animal farming was conducted, to synthesize key factors considered for the design process of the system data flow, microservice definition and the environmental monitoring system technology selection.
Results: A cloud MSA with a multi layered scheme using the Amazon Web Services (AWS) platform was developed, validating the persistence of environmental data transmitted from WMSN prototype nodes to be deployed in mobile chicken coops.
Conclusion: Defining an End-to-End data flow facilitates the organization of tasks by domains, allowing efficient event communication between components and network reliability both at the hardware and software levels.
Originality: This study presents a novel design for a remote environmental monitoring system based on WMSN for mobile coops used in pastured poultry and a multi layered MSA cloud management platform for this specific type of food production industry.
Limitations: Software architecture technology selection was based only on services offered, to the date of the study, in the free tier of the Amazon Web Service platform.
Prominence as an anchor for a clitic: prosody-sensitive placement of the conditional subordinator ki 'if' in Kazym Khanty
Authors: Belkind Aleksandra
Published: June 2023

Research on clitics usually distinguishes between syntactic and phonological clitics (e.g. Embick & Noyer 2001; Anderson 2005). The latter ones are treated as highly locally restricted (Embick & Noyer 2001): they can be dislocated to the nearest possible host, i.e. attach to a nearest overtly realized head in the clausal spine or flip order with the nearest full word, irrespective of its category. Such analyses makes a prediction that phonological clitics cannot skip full words or overtly realized heads, when they are seeking for a host. In more recent research some counterarguments to this prediction have been introduced, e.g. Irish pronominal clitics (Bennett et al. 2016) and Tiwa focus clitic (Dawson 2017), which are displaced in the prosodic structure and are sensitive to bigger constituents, i.e. phonological phrases. A goal of this paper is to provide one further counterexample to this generalization and to argue that not only phonological phrases, but also prosodic prominence can play a role in clitic displacement. Namely, I describe the behavior of the conditional clitic in Kazym Khanty (Ob-Ugric, Uralic) and argue that its placement can be only analyzed as a prominence-sensitive displacement in the hierarchically organized prosodic structure. I argue that the conditional clitic in Kazym Khanty attaches to the most prosodically prominent prosodic phrase, which is defined independently. The distribution of Kazym Khanty ki ‘if’ also allows to falsify a descriptive generalization that all C-clitics stay close to the edges of a clause. This is indeed not the case with ki, since the correct analysis of the data must allow it to leave its base-position and occur clause- and phrase-internally (contra Embick & Noyer 1999). The study is based on my own fieldwork with native speakers of Kazym dialect of Nothern Khanty language (Ob-Ugric, Uralic).
Lignite industry of Russia: peculiarities of the development concept
Authors: Kalinskiy O. I. , Goncharov M. S. , Skryabin O. O.
Published: June 2023

A long-term development concept for Russia’s lignite industry has been presented, developed based on a comprehensive evaluation of active coal mining companies. The economic indicators of 48 Russian companies engaged in lignite mining were analyzed, both nationally and regionally, allowing for specific provisions of the concept to be formulated accounting for the spatial development of industry companies.

The relevance of this work is due to the high strategic significance of the lignite industry for the country’s economy, which is in ensuring energy security for the Far East and Siberia on a long-term perspective of up to the depletion of explored lignite reserves in 1137 years with the current level of mining. Despite the high strategic importance of the industry, there is a risk of a decrease in its role in the country’s economic development, as the industry has faced several internal and external challenges. These challenges require a quick response to prevent potential damage they may cause.

The results of the analysis of the current state of Russia’s lignite industry are presented in terms of the distribution of explored lignite reserves, the territorial localization of active coal mining organizations, their production and economic conditions, and their associations with the external environment. Based on the results of the analysis, a concept and principles for industry development have been formulated. The concept involves increasing lignite mining in the Far Eastern Federal District and maintaining the volume of mining in the Siberian Federal District, achieved through creating necessary conditions for economic development, including diversification of products produced from lignite.

Today universities are creating all conditions for successful training, improving the graduates’ competitiveness at the labour market and employment according to the qualification received. In the conditions of social and economic transformations a significant number of young specialists are not able to adapt to the labor market. This is caused by lack of practical experience and the resulting low professional status. The balance between the labor market needs for young specialists and the universities’ ability to educate them can be achieved by close interaction between the professional educational institutions and potential employers. To coordinate the interests of both experts apply various interaction models able to ensure harmonization of the process.

The article in hand deals with four models of interaction between the university career centres and partner companies which use two models of such interaction in the Southwest State University. The authors analyzed the level of integration of the career centres with other structural departments of the university showing the link between the interaction model implemented in the university and the level of integration. The research allowed to make a conclusion about sufficient influence the university career centres’ activities on the graduates’ competitiveness at the labour market.

Cooperation of universities and employers is aimed at implementing a complex of measures, means and methods which ensure providing the appropriate level of professional education. Also it contributes to solving the following tasks: engagement of the companies in the graduates’ employment according to their qualifications, participation of the university staff in scientific research activity within the topics suggested by the companies, involvement of the partner companies to career guidance activities and events aimed at developing the information environment in the labour market and increasing the attractiveness of the employer’s brand in the eyes of graduates.

Regional universities are facing the problem of the graduates’ employment in the city – forming enterprises and companies operating in the region. Taking into account that young specialists tend to migrate to the regional centres, it is essential to take measures to increase the attractiveness of work conditions with the emerging trend of staff outflow. Promotion of employment of young specialists can be effective only in case of establishing long-term “university-student-employer” partnership.
Temperature Forecasting as a Means of Mitigating Climate Change and Its Effects: A Case Study of Mali
Authors: Billy Utibe
Published: June 2023

Temperature forecasts and trend analyzes were carried out for several locations in Mali as an important tool for warning of potentially threatening weather events such as severe heat waves, storms, droughts and floods, which could pose a great risk to humans and their environment. Five locations (Segou, Sikasso, Kayes, Gao and Taoudenni) across Mali (170 00’N – 40 00’W) were chosen for this research work. Satellite data of annual temperature obtained from the European Centre for Medium-Range Weather Forecast (ECMWF) database for 35 years (1985-2019) was used for this work. The Mann-Kendall trend test was carried out for various locations to observe and study the trend. Four Models including Auto Regressive and Integrated Moving Average (ARIMA), Exponential smoothening (ETS), TBATS (Trigonometric seasonality, Box-Cox transformation, ARMA errors, Trend and Seasonal components) and the linear model were employed to forecast average temperature for 10 years for all the locations. The model that produces the best forecast at the 95% confidence level is expected to have the lowest Root Mean Square Error (RMSE) value. The results showed that no significant trends were recorded at the considered locations. The linear model produced the best forecast for Segou, Kayes and Taoudenni, while the TBATS model produced the best forecast for Gao and the ARIMA model produced the best forecast for Sikasso.

Albrecht introduced the concept of hamartoma at the beginning of twentieth century to designate a tumor like or non-neoplastic malformation or inborn error of tissue development. They arise virtually in all organs. They may derive from any three germinal layer of which mesodermal derived overgrowth is most common. They are slow growing and have self-limited growth. The formation of these growth take place by abnormal mixing of tissue in course of development. Present retrospective study was conducted in pathology department over a period of 2 years from July 2020 to June 2022. Total twenty cases were included in study and it was observed that twelve cases occurred in head and neck region, one case occurred over chest, one case in gastrointestinal tract and six cases in extremities. It is important to differentiate hamartomas from related lesions like choristoma, teratoma and benign tumors to avoid aggressive treatment.

Authors: Hegde Akanksha , Mysorekar Vijaya
Published: June 2023

Synovial sarcoma (SS) is a rare type of high-grade soft tissue sarcoma that accounts for 5% to 10% of all soft tissue tumors. It primarily affects the soft tissue of the arms and legs. The rate of lymph node metastases in synovial sarcoma is 3% to 7%.

They are locally aggressive and have a higher metastatic potential. The overall prognosis of patients is poor due to systemic metastasis. Immunohistochemistry and molecular studies are indispensable in the diagnosis of these tumors.

We present to you a case of biphasic synovial sarcoma of left thigh in a 70-year-old lady with lymph node metastasis and squamous differentiation.

Published: June 2023

Idiopathic pleuroparenchymal fibroelastosis is a rare idiopathic interstitial pneumonia which mainly affects the upper lobe of lungs resulting in intra alveolar fibrosis, elastosis and visceral pleural fibrosis. For definite diagnosis, radiographic findings as well as histopathology findings are required. The overlap with interstitial lung diseases seen usually, makes it challenging to diagnose. There are no guidelines available for the diagnosis and appropriate management of this disease and only a few cases reported in the literature. We report a case of pleuroparenchymal fibroelastosis in autopsy in a 32-year-old female who allegedly died of heart failure with review of literature.

Authors: Thomas Rose Maria , Reddy Purushotham
Published: June 2023

Fibrosarcoma is a malignant tumour arising from fibroblasts. Several variants have been described and these prove to be a diagnostic challenge owing to its many mimics, thus often requiring ancillary testing such as immunohistochemistry. The sclerosing epithelioid variant is a poorly recognised entity that poses a therapeutic dilemma. This is a case of Fibrosarcoma-sclerosing epithelioid variant reported in a 62-year-old male who presented with an exophytic lesion on the sole of the foot and was operated for the same. This article stresses on the systematic approach to such a case which will enable the pathologist to arrive at an accurate diagnosis.
