A zöldöv szerepe a szöuli területrendezésben
Authors: Koudela Pál
Published: March 2022

Dél-Korea rendkívül gyors urbanizációja, különösen Szöul népességének növekedése az 1960-as években számos területrendezési megoldás bevezetésére késztette az ország vezetését, melyek közül legmaradandóbbnak az 1971-ben életre hívott zöldöv bizonyult. A tanulmányban elsőként röviden felvázoljuk a Szöult érintő népességkoncentráció változását, majd az urbanizáció okozta társadalmi-gazdasági és ökológiai problémák kezelésére bevezetett területi szabályozás eszközeit és azok hatását vitatjuk meg, különös tekintettel a gazdasági korlátozásokra és az intézmények területi szabályozására. A tanulmány második felében a Szöul központjától tizenöt kilométerre fekvő, s mintegy tíz kilométer széles zöldöv kialakításáról esik szó.
A zöldövnek elsődlegesen nemzetbiztonsági célja volt, mert Szöul közel fekszik az északi határhoz, s csak másodlagosan szolgálta a városi szétterülés megakadályozását, a város körüli illegális nyomornegyedek felszámolását és egyéb célokat. A londoni példa nyomán, több ütemben létesített zöldöv több előnye, így a levegő minőségére, a hőháztartásra és a biodiverzitásra gyakorolt kedvező hatása mellett több problémát is okoz. A zöldövnek köszönhető decentralizáció csupán részleges eredményeket ért el: a külső területek fejlődésével növekvő infrastrukturális (utak, vasutak), társadalmi (ingázás számának és idejének növekedése) és környezeti (levegőszennyezés) költségeket teremtett. Közvetett módon a zöldöv a termelékenységet is csökkentette, ráadásul a kevésbé értékes területek megőrzése a külső, értékesebb területek rovására történt. Az elmúlt évtizedekben többen is elemezték a zöldöv gazdasági, társadalmi és ökológiai hatásait, e munkák alapján, és a zöldöv másodlagos hatását, így a Szöulban legutóbb bevezetett környezetvédő programokat is figyelembe véve, összességében pozitívan értékeljük a zöldöv társadalmi-gazdasági hatásait.
Szétfejlődés vagy útfüggőség? Trianon hatásai a fejlettség földrajzi különbségeire a történeti Esztergom és Komárom vármegyék területén.
Authors: Mikle György
Published: March 2022

Tanulmányomban a történeti Esztergom és Komárom vármegyék területi különbségeinek 1910 és 1941 között lezajlott változásait vizsgáltam települési léptéken, a történeti földrajz kvantitatív módszerei segítségével. A területnek a Duna bal partján található részén 1919 és 1938 között a Csehszlovák állam szándékai alakították a helyi társadalmak körülményeit. Ezen a területen fontos esemény volt a csehszlovák földosztás, amely egyben az utódállam nemzetiségi politikájának részét is képezte, így kiemelt figyelmet szenteltem a földműves népesség helyzetének, a birtokviszonyok alakulásának. Az 1910-re és 1938/1941-re elvégzett számítások alapján a fejlettség komplex mutatói a korszakban elsősorban a népesség foglalkozási szektorok szerinti megoszlása mentén differenciálódtak, így a tartósan fejlett területek a történeti vármegyéknek a bányászati tevékenység által jellemzett települései, valamint a városok voltak. Amíg az első világháború előtt a fejlettségi rangsor végén zömmel a Duna bal partján fekvő települések voltak, addig az első (1919 és 1938 közötti) csehszlovák korszak végére ezeken a területek számos település előbbre lépett a rangsorban. Ezek főleg olyan települések, ahol az első világháború előtt a mezőgazdasági keresők több mint kétharmada cseléd, vagy mezőgazdasági munkás volt, azonban az első bécsi döntés idejére arányuk 50% környékére, vagy az alá csökkent. Mindeközben a történeti Komárom vármegye északkeleti része, valamint a Kelet-Csallóköz és a vármegye déli része tartósan alacsonyabb fejlettségű területnek számított a vizsgált területen belül. Ennek alapján az elemzett három évtizedben nem beszélhetünk a terület Duna bal és jobb partán fekvő településeinek szétfejlődéséről, hiszen sokkal erősebb volt a népesség foglalkozási megoszlása által meghatározott útfüggőség, amely inkább egy keleti-nyugati kettősséggel jellemezhető.
Protestáns kultúrrégiók a 19. század első felében Az akadémiai csúcselit kollektív biográfiai elemzésének néhány társadalomföldrajzi tanulsága
Authors: Ugrai János
Published: March 2022

Tanulmányunkban a reformkori Akadémia protestáns tagjainak földrajzi hovatartozását vizsgáltuk kollektív biográfiai eszközökkel. A tanulmányi pálya és a felnőtt életutak állomásait kultúrrégiókhoz soroltuk. Ezt követően a kultúrrégiók egymáshoz viszonyított arányát, akadémiai reprezentációjuk erejét, illetve a személyek kultúrrégiók közötti mozgását, földrajzi mobilitásuk nagyságát és intenzitását határoztuk meg.
A vizsgálatot az tette lehetővé, hogy a reformkori Akadémia különböző metszésvonalak mentén egyensúlyozó mechanizmusokat működtetett, s így felekezeti és földrajzi értelemben is egyfajta reprezentativitásra törekedett. A nemzeti kibontakozás jegyében ráadásul nemcsak tudományos, hanem nyelv- és művészetpártoló, művelődésszervező célkitűzései is hangsúlyosak voltak. Ily módon nemcsak a tudományos, hanem a tágabban vett szellemi elit egészének összetételére érvényes következtetéseket vonhatunk le. A tanulmányban alkalmazott kultúrrégió kifejezés pedig az egyházi társadalomtörténetben már ismert „felekezeti–művelődési alakzat” kiterjesztésének, a térbeli tagolódás megjelenítésére alkalmas elágazásának tekinthető.
A reformkorban a Magyar Tudós Társaság tagjává választottak 28%-a református, 12%-a evangélikus volt. Mindkét felekezet felülreprezentált volt tehát az összlakosságban elfoglalt súlyához képest, de a felülreprezentáltság mértéke jellegzetes különbséget mutat. A reformátusok esetében ezzel a módszerrel is kimutatható Debrecen, mint szellemi központ kimagasló ereje – és egyúttal erőteljes zártsága. Debrecenhez hasonló arányban delegált akadémikusokat az erdélyi református kultúrrégió, amely azonban nem kizárólag Kolozsvárhoz, hanem részben Nagyenyedhez és Marosvásárhelyhez kötötte a kulturális élet vezéreit. A decentralizáció jegyei a többi református kultúrrégióban is kimutathatóak. Az evangélikus kulturális csúcselit körében még jellemzőbb a decentralizáltság – ennek érzékletes példáját a hagyományos, legerősebb iskolaközpont, Pozsony látványos „gyengélkedése” szolgáltatja.
A református kultúrrégiók esetében szembeszökő, hogy hiába éltek jelentős arányban kálvinisták a Dél-Dunántúlon, az Alföld felén és Észak-Tiszántúlon, nem rendelkeztek olyan iskolavárossal, szellemi központtal, amely alkalmas lett volna legalább egy-két akadémikus kinevelésére. Mindez természetesen újra csak Debrecen egészen különleges szerepére világít rá. Ehhez képest másféle stratégia jellemezte az evangélikusokat, akiknek nemcsak észak-magyarországi érdekeltsége volt kiterjedt, de a Dél-Alföldön is rendelkeztek akadémiai kapcsolatokkal.
A reformkori akadémikusok mobilitását vizsgálva Debrecen és Erdély önállóságához (és zártságához) nyertünk újabb érveket, emellett pedig Pest immár egyre erőteljesebb vonzó hatása támasztható alá meggyőző számokkal.
A települési egyenlőtlenségek új dimenziója: a mezőgazdasági földhasználat-szerkezet

Published: March 2022

Tanulmányunk célja a magyarországi települések földhasználat-szerkezet szerinti csoportjainak kimutatása, és annak vizsgálata, hogy van-e összefüggés a települések fejlettségi mutatói és a földhasználat szerkezete között. Annak ellenére, hogy a földhasználat széles körben kutatott, kevés olyan elemzést találunk, amely települési szintű adatokra épül. Kutatásunk hozzáadott értékét az adja, hogy – eltérve a szakirodalom adathasználatától – megfigyelési egységnek a települést tekinti. Elemzésünk során első lépésben az EU egységes területalapú támogatási (SAPS) adatok alapján a földhasználó gazdaságok adatbázisát alakítottuk ki, majd ez alapján hoztunk létre egy településszintű adatbázist, melyet összekapcsoltunk településsoros mutatókkal. Látens profilelemzés segítségével a földhasználat-szerkezet szerint a települések hat jellegzetes csoportját tártuk fel, amelyek a korábbi kvalitatív munkák szerint is jól azonosíthatóak. A települések fejlettségi mutatóinak a földhasználat-szerkezettel történő összekapcsolása arra mutatott rá, hogy a vegyes, a szegmentált és a nagybirtok dominanciájú földhasználat-szerkezeti struktúra olyan településekre jellemző, amelyek fejlettségi mutatói rendre meghaladják a szétaprózott földhasználati szerkezetű települések mutatóit. A települések földhasználat-szerkezete további kutatásokat igényel, az azonban már most is megállapítható, hogy a települések közötti egyenlőtlenségek egy olyan lényeges dimenzióját sikerült bemutatni, amely a kutatásokban eddig kevéssé kapott figyelmet.

O controle químico de patógenos em sementes é realizado principalmente com o uso de fungicidas sintéticos, havendo a necessidade de alternativas que não contaminem o meio ambiente e o homem, destacando-se assim o controle biológico, através do uso de antagonistas como Trichoderma spp. Logo, o presente trabalho objetivou avaliar a influência de Trichoderma spp. sobre a sanidade e aspectos fisiológicos de sementes de Astronium urundeuva (M. Allemão) Engl. Os tratamentos foram aplicados por contato direto das sementes com o fungo e consistiram de testemunha (apenas assepsia); fungicida captana® (240 g 100 kg-1 de sementes) mais sete diferentes isolados de Trichoderma sp. As sementes inoculadas com Trichoderma sp. foram acondicionadas sobre colônias de Aspergillus sp. e mantidas nessa condição durante 24 horas pelo método de contato direto. Após a aplicação dos tratamentos, as sementes foram submetidas aos testes de sanidade, germinação e emergência. A utilização de Trichoderma spp. foi eficiente na redução da incidência de Aspergillus niger. em sementes de A. urundeuva e incrementou a germinação das sementes e vigor das plântulas.

O cultivo de plantas de cobertura na entressafra ou em rotação de culturas pode ser adotado como estratégia para melhorar as características físicas, químicas e biológicas do solo, além de preservá-lo contra os processos erosivos. Diversas espécies de gramíneas e leguminosas podem ser utilizadas para esta finalidade, e cada uma apresenta uma dinâmica peculiar em relação a velocidade de cobertura e persistência de sua palhada no solo. Objetivou-se com este trabalho analisar a dinâmica das taxas de cobertura e decomposição de plantas de cobertura e o efeito do sistema radicular dessas espécies sobre atributos físicos do solo. O delineamento experimental utilizado foi de blocos casualizados, com onze tratamentos e quatro repetições, constituídos pelas espécies de plantas de cobertura Brachiaria brizantha Hochst. (Stapf), Crotalaria bleviflora, Crotalaria juncea, Crotalaria ochroleuca, Stylosanthes capitata + Stylosanthes macrocephala, Canavalia ensiformis, Cajanus cajan cv. IAC/Fava-larga, Cajanus cajan cv. IAPAR 43, Pennisetum glaucum, Mucuna cinereum e Mucuna aterrima. As taxas de cobertura do solo foram avaliadas aos 20, 40, 60 e 80 dias após a semeadura. As taxas de decomposição dos resíduos vegetais foram analisadas em intervalos regulares de 15 dias, contadas a partir do corte das plantas. As espécies Canavalia ensiformis, Mucuna cinereum e Mucuna aterrima cobriram plenamente o solo aos oitenta dias após semeadura e o Pennisetum glaucum apresentou a maior persistência da palhada decorridos sessenta dias após o corte.

O objetivo deste estudo foi avaliar o autocuidado e o risco cardiometabólico em pessoas com hipertensão arterial (HA) em seguimento clínico regular na atenção primária à saúde. Estudo analítico e transversal conduzido entre 86 pessoas com HA no interior do Estado de São Paulo, por meio da aplicação das versões brasileiras da Escala de Autocuidado de Hipertensão e do Escore de Risco Cardiometabólico de Framingham. Os participantes demonstraram níveis satisfatórios de confiança (71,3(14,7)), níveis insatisfatórios para manutenção (59,2(14,5)) e manejo (55,1(20,3)) do autocuidado na Escala de Autocuidado e 34,6% de chance de desenvolver infarto agudo do miocárdio nos próximos dez anos. Os indivíduos com menor idade apresentaram níveis de confiança satisfatórios em relação ao manejo do autocuidado, e observou-se maior risco cardiometabólico entre pessoas com diabetes e angina. Os indivíduos possuem confiança, mas demonstram inadequados manejo e manutenção do comportamento de autocuidado, e quanto menor a idade, melhor o manejo do autocuidado.

The purpose of the study was to investigate the effects of Kinesio Tape (KT) on scapular kinematics with different external loads in healthy subjects. Twenty-three subjects performed abduction, scaption and flexion of their shoulders in three conditions: (1) no load (2) dumbbell and (3) elastic band resistance. KT was applied (I-shaped) over the upper trapezius muscle, and scapula kinematic data was captured and analyzed based on Euler angles. The situations and interactions of the different loads and KT were compared using a repeated measures two-way ANOVA. KT decreased the upward rotation during the movements of abduction, scaption and flexion of the shoulder. There was an effect of load in all evaluated movements, but there was no interaction between the load and the KT. It can be concluded that KT and load showed effects on scapula kinematics. Regardless of the load condition (no load, dumbbell or elastic resistance), the effects of the KT on scapula kinematics will be the same in healthy subjects.
Numerical Models of Ice Giant Interiors

Published: March 2022

Planetary magnetic fields are an important source of information about interior processes that are otherwise unobservable. Uranus and Neptune were discovered to have magnetic fields in the 1980s after encounters with Voyager 2. Unlike the other giant planets of the solar system, Uranus and Neptune have non-dipolar, non-axisymmetric magnetic fields. The results of previous numerical experiments are able to account for such magnetic fields through strongly driven convection. However, another property that Uranus and Neptune share are smaller internal heat sources than the other giant planets. In this work, we test the hypothesis that convection that is driven either entirely or partially by a chemical source in the deep interior is able to account for dynamic, thermal, and magnetic properties of the ice giant planets. To do so we introduce a set of numerical models including both rotating convection and self-consistent dynamos, that vary the relative contribution of thermal and compositional convection, including double-diffusive convection models. We find that these models are generally able to produce velocity fields that are similar qualitatively to the observed zonal winds of the ice giants, as well as multi-polar magnetic fields. By displacing thermally driven convection with compositionally driven convection, we demonstrate the possibility that the ice giants may undergo sufficiently vigorous convection to both drive zonal flows and to sustain the magnetic field without introducing a large heat flux.
The Role of NetrinG1 in Stroma-derived Extracellular Vesicle-mediated Survival of Pancreatic Ductal Adenocarcinoma during Nutrient-deprivation
Authors:   , Raghavan Kristopher S. , Cukierman Edna
Published: March 2022

Pancreatic Ductal Adenocarcinoma (PDAC) is a devastating disease which is, in part, driven and supported by changes in its microenvironment or stroma. These changes occur early, yet the majority of PDAC cases are undiagnosed until after the disease has metastasized, causing survival rates to drop tenfold. Therefore, there exists a grave importance to detect this disease as early as possible and understand its progression. This dissertation investigates the intercellular communication that exists between the primary stromal component, cancer associated fibroblasts (CAFs) and PDAC cells. Specifically, this study focuses on the mechanism by which CAF-secreted extracellular vesicles (EVs) promote PDAC survival. EVs are heterogeneous populations of membrane structures used to transfer material between cells. This investigation highlights specific populations of EVs including exosomes and exomeres. An additional goal of this work aims to identify potential EV-biomarkers suitable to generate a noninvasive "liquid biopsy" test for early PDAC detection and prognosis assessment. This study reports distinct types of CAF-derived EVs containing unique surface receptors. One novel surface protein, NetrinG1, is expressed on the plasma membrane of pancreatic CAFs, but absent in nonpathogenic fibroblasts. Functional assays designed to test PDAC viability under nutrient deprivation show CAF EVs can protect PDAC cells from the induction of apoptosis. Analysis of CAF EV cargo suggest that this EV-mediated survival benefit is caused by NetG1-dependent changes in proteins and metabolites being transferred to nutrient-stressed PDAC cells. This work also identifies distinct subtypes of CAF-derived EVs containing unique cargo and surface receptors including NetrinG1; these CAF-derived EVs localize to novel exomere subpopulations, suggesting the secretion mechanism is distinct from canonical exosome trafficking. An additional protein receptor, Integrin [alpha]5, was observed in exosome structures, supporting previous reports of its subcellular localization in CAFs being associated with a pathological state. Supporting the potential for disease detection, NetrinG1 and Integrin [alpha]5 in EVs from human plasma were shown to be significantly enriched in PDAC patients. Additionally, this investigation provides early evidence that the extracellular matrix differentially binds subpopulations of EVs based on surface markers. This suggests that the extracellular matrix can play an important role in determining the biodistribution of secreted EVs in vivo, which has significant implications for what EV subpopulations maybe be found circulating systemically in blood or acting locally in a paracrine manner within the tumor microenvironment. Altogether, this research elucidates a novel mechanism of tumor-stroma communication and introduces functional EV subpopulations potentially capable of identifying PDAC occurrence in humans.

Work archivists do to make collections broadly accessible is critical to the use of unique evidential primary sources in repositories. Use of primary sources in interdisciplinary research contributes to information science and its role in global health and sustainability practices, yet scant research investigates archivists' role in this information-intensive work. My qualitative case study in the naturalistic paradigm is the first to study the complex social phenomenon of archivists' work from the perspective of persons doing this work at history of medicine collections in Philadelphia. It is among the first to bring to the archival context sensitizing concepts grounded in LIS literature on human information behavior, information practice, information work, and communities of practice. Two research questions explore archivists' work: "How do archivists produce and put information to use through information work and information practices at medical history collections in Philadelphia?", and "How can a theoretical framework based on sensitizing concepts in information practice, information work, and communities of practice literature refine analysis of archivists' production and use of information through information work?". The theoretical framework's four components outline four distinct yet interrelated work contexts to analyze behind-the-scenes work of processing and curation as well as the visible work of reference services and outreach. Purposive and snowball sampling techniques recruited eleven informants at six of Philadelphia's ten special collections registered in the National Library of Medicine Directory of History of Medicine Collections. Data collection bracketed six months before and after COVID-19 onset in Philadelphia and included semi-structured interviews, analytic memos, and empirical documentation. Data analysis indebted to constructivist grounded theory relied on a human instrument, emergent design, the constant comparison method, and inductive reasoning. Trustworthiness criteria and measures mitigating bias ensued from project onset. Findings demonstrate that participants put information to use through trajectories of layered information work. In conclusion, the sensitizing concepts elucidate participants' personal and professional agency in embodied and affective information work. Archivists' work is a form of collections use and an information practice that underlies discovery and access to primary sources. Implications concern recognition of archivists' information practices as part of archival and information science research.
Toying with Identity

Published: March 2022

One need only look at current toy aisles to see the industrial legacy of toyetic transmedia franchises like Star Wars, Transformers, Teenage Mutant Ninja Turtles, Masters of the Universe, Care Bears, and My Little Pony. However, the increasing popularity of vintage toy collection, curation, and commerce by adults of specific generations, suggests a deeper connection to the media of that era. Today, the toys, animated series, and other media are collectible connections to the past and markers of generational belonging for a significant number of adults who fell in love with toyetic media as kids. The fandom around these toys and their transmedia narratives should not be dismissed as pure nostalgia, nor should this decade's impact on children's consumer culture be overlooked. The Reagan era of deregulation in 1980s paved the way for advertisers, animation studies, and toy manufacturers to synergistically cultivate a new toyetic approach to children's marketing which significantly impacted Gen Xers and Millennials. Toyetic is a term commonly used by marketing professionals to describe the potential for making toys from a media property. Toyetic also describes a specific transmedia genre that emerged in the 1980s, specifically to sell toys, not as ancillary merchandise, but the primary product sold through highly coordinated transmedia systems. Adults who came of age during this period were the first to be groomed under this new toyetic transmedia genre which cultivated a new children's consumer culture and planted the seeds of brand loyalty that now manifests in vintage toy fandom. Toy fandom is also illustrative of how recent generations are socially constructed media audiences that nostalgically share collective memories and comradery built around the books, comics, films, television shows, cartoons, and toys of their youth as part of both their individual and social identities.

Published: March 2022

These days pesticides are extensively applied in agriculture to increase productivity; although these pesticides increase productivity but also have a negative impact on the consumer. Thus, pesticide exposure in agricultural products must be decreased. The present study attempted to assess pesticide residues in samples of apple, tomato, and brinjal and determine the efficacy of washing solutions in pesticide removal. For sample preparation, the QuEChERS method was employed, and prepared samples were analyzed using gas chromatography-mass spectrometry. Results of the study revealed that among the collected samples, 58.33 percent samples were showing lower pesticide residues as compared to the maximum residue limit (MRL) while 12.5 percent of the samples were showing higher pesticides residues as compared to the suggested MRL. Further, from the collected fruits and vegetable samples, the presence of the chlorantraniliprole, carbendazim, beta endosulfan, chlorpyrifos, malathion, carbaryl, thiomethoxam, DDT, and flubendiamide were detected in the range of 0.0–1.41 mg/kg. Among the detected pesticides, chlorpyrifos and flubendiamide were the most commonly detected pesticides. Effectiveness of different washing solutions was studied, which indicated a significant reduction in residues of all the washing solutions compared with the control (p < 0.05) and concluded that ascorbic acid and sodium bicarbonate solution was very effective in pesticides removal compared with water and chemical alone.

COVID-19 has been categorized as a pandemic in early 2020 and is known to cause by Severe Acute Respiratory Syndrome Coronavirus (SARS–CoV2). Numerous investigators and people in the scientific community are trying to find a superlative way to avert and cure the ailment by using phytochemicals. Abundant studies have revealed that flavonoids can be very operative in averting virus-mediated infection. The purpose of this study was to accomplish molecular docking studies among plant-derived flavonoids (Apigenin, Kaempferol, and Quercetin) and spike receptor (PDB ID: 2AJF) protein of coronavirus. Pyrx virtual screening tool and biovia discovery studio visualizer were utilized in the current molecular docking investigations. Outcomes of docking studies exposed that selected phytochemicals have interacted with targeted spike receptor protein with binding energies in the range of -6.3 to -7.3 kcal. In conclusion among the various selected ligands, quercetin may be a better inhibitor for the deactivation of SARS-Coronavirus.
Effects of Rauwolfia serpentina L. Benth. ex Kurz (Serpentina) and Costus igneus Nak. (Insulin plant) leaves crude extracts on the blood glucose levels of alloxan induced albino rats
Authors: Fauni-Guirre Gladys , Ching Johnny A.
Published: March 2022

The prevalence of treatment failures from dietary patterns and oral medications associated with diabetes have generated adverse effects and are oftentimes expensive. Recently, food-based therapies such as Rauwolfia serpentina (serpentina) and Costus igneus (insulin plant) have been received much attention due to the urge for an alternative and safe solution against diabetes. Thus, the hypoglycemic effects of serpentina and insulin plant leaf crude extracts were determined on the blood glucose level of test rats. Twenty-four alloxan-induced male albino rats were subjected to this experimental study distributed into six groups in a completely randomized design. The negative control (NEG) comprised of diabetic rats receiving no treatment; while the positive control (MET) comprised of diabetic rats treated with metformin; experimental groups include IN1X and IN2X for the diabetic rats treated with extracts of insulin plant leaves administered once and twice daily and SER1X and SER2X for the diabetic rats treated with extracts of serpentina leaves administered once and twice daily. Results of the study revealed that both serpentina and insulin plant leaves crude extract demonstrated hypoglycemic effects due to the presence of zinc that potentiated insulin action. Further, the insulin plant improved glucose and insulin levels due to quercetin which reduced oxidative stress and protects DNA damage, β-amyrin and β-L-arabinose methyl glucoside which builds-up insulin for glucose metabolism. The presence of significant phytochemical contents in the insulin plant has been attributed to the stimulation of β cells. In conclusion, insulin plant leaf crude extract elucidated better hypoglycemic activity than the serpentina plant leaf crude extract in the blood glucose levels of alloxan-induced diabetic rats.
Effect of probiotic Bacillus spp.-supplemented feed on the growth, length-weight relationship, and condition factor of Nile tilapia (Oreochromis niloticus)
Authors: Samson Jaypee S.
Published: March 2022

This study was carried out to evaluate the effect of two probiotic Bacillus spp. (RM10 and BFAR9) on the growth, length-weight relationship (LWR), and condition factor (k) of Nile tilapia (Oreochromis niloticus). For this, one hundred thirty-five fingerlings (1.12±0.08 g weight and 1.26±0.15 cm length) were divided into three groups (Control, RM10, and BFAR9) and distributed into nine circular concrete tanks. The fish were fed with commercial (control) and Bacillus spp. supplemented diets at 5% of body weight for 56 days. The results of the study revealed better (P<0.05) growth concerning average body weight (ABW - 17.12±0.71g), specific growth rate (SGR - 4.89±0.22 g·day-1), absolute growth (AG - 16.02±0.78 g), and feed conversion ratio (FCR - 1.31±0.09) in the group fed with Bacillus sp. RM10 as compared to the control (ABW- 13.25±2.34g; SGR - 4.41±0.17g·day-1; AG - 12.13±2.25g; FCR - 1.62±0.11). The LWR in all experimental treatments showed a significant correlation (P<0.05) with an R2 value of 0.988, 0.966, and 0.979 for Control, RM10, and BFAR9, respectively. The k value revealed that all treatments are in good condition as k value is greater than 1 (1.913, 2.038, and 1.896 for control, RM10, and BFAR9 respectively). The result of the current study revealed that application of Bacillus sp. RM10 improves the growth and feed utilization in Nile tilapia.

В процессе обогащения углей образуются огромные объемы отходов, которые, как правило, выбрасываются в окружающее пространство, загрязняя его. При этом отходы могут содержать до 50% углерода. Малая промышленная энергетика, муниципальные котельные используют преимущественно слоевое сжигание углей. При этом коэффициент выгорания углерода составляет 50–60%, и коэффициент полезного действия котлов нередко не превышает 60%, а их экологические показатели не удовлетворяют современным требованиям. Эффективным способом решения проблемы утилизации углеотходов может оказаться перевод котлов на сжигание углей в виде водоугольной суспензии (ВУС). В статье представлены результаты авторов по технологии приготовления водоугольного топлива (ВУТ) и его сжиганию в вихревых топках котлов. Представлены данные по новому оборудованию, необходимому для реализации технологии. Показано, что и рядовые угли, и антрацит, и угольные шламы, а также отходы углеобогащения могут служить основой для производства ВУТ. Приведены примеры опытно-промышленного применения водоугольной технологии. При этом коэффициент выгорания топлива достигает значений порядка 95%, а коэффициент полезного действия котлов превышает 85%.

Coal is the main fuel of thermal power plants (TPP), which provides more than 40% of electricity generation and about 25% of thermal energy in the world. Unlike renewable energy sources, thermal power plants supply consumers with energy around the clock and without interruption, regardless of the time of year. Expensive highly reactive fuel (fuel oil or natural gas) is burned to kindle pulverized coal boilers of thermal power plants. The burning of heating oil leads to an increase in harmful emissions into the atmosphere and initiates the search for alternative solutions for fuel-free kindling of pulverized coal boilers of thermal power plants. The most effective solution to this problem is the use of innovative plasma technology for fuel-free boiler kindling. Currently, much attention is paid to the fight against global warming and related environmental problems that lead to a negative impact on people, animals, and plants. The installation of plasma-coal burners in the furnaces of power boilers, providing their fuel-free kindling and illumination of the pulverized coal torch, significantly improves the environmental and economic indicators of thermal power plants. Currently, one of the priority tasks is to optimize the design of plasma-coal burners at existing thermal power plants.

В данной статье приведены результаты гидрогенизационной переработки угля Шубаркольского месторождения в присутствии природных бокситов Тургайского месторождения Республики Казахстан. Установлено, что модифицирование железосодержащих катализаторов добавками элементарной серой (0.75-1.25%) позволяет увеличить выход жидких продуктов до 62.3-67.3%. Показана положительная роль предварительного озонирования угля, которое позволяет при гидрогенизации увеличить выход суммарных жидких продуктов на 13.3%. Для выявления влияния радиационного воздействия на выход жидких продуктов уголь и катализатор предварительно облучался потоком электронов на ускорителе электронов ЛУ-6. При этом выход жидких продуктов увеличивается от 54,2 до 68,5 мас.%. Для выявления влияния механической обработки на процесс гидрогенизации исходный уголь измельчали на мельнице Polymix PX-MFC 90 D в течение 15-60 мин. Максимальный выход наблюдается при 30 мин обработке. Методом ЭПР показано, что при радиационной и механохимической обработке угля наблюдается увеличение концентрации СРС и трехвалентного железа. Эти изменения в угольной макромолекуле могут положительно влиять на процесс гидрогенизации и приводят к возрастанию выхода жидких продуктов.

New technologies and methods designed to reduce the risk and magnitude of surgical manipulations are being actively introduced into clinical practice, one of which is the method of high-intensity focused ultrasound (HIFU) thermoablation. However, it is quite difficult to assess the spatial distribution of acoustic and thermal fields when selecting a therapy scheme. To simulate the architectonics of the treatment area it is proposed to use a dosimetric phantom. The pattern of changes in the phantom in the heat-affected zone is shown with an ultrasound scanner in real time, which allows to visualize structural changes in the area of thermal destruction and verify the dosimetric plan of ultrasound therapy.

Nowadays, Kazakhstan is experiencing a shortage of fresh groundwater resources, which in the future may lead to a complete depletion of this type of resources. One of the most promising sources of drinking fresh water in our country is the Kokzhide groundwater field, the state of which has deteriorated under the influence of oil production enterprises. The aim of the research was to conduct an environmental assessment of the state of the underground lake Kokzhide, taking into account the impact of the activities of oil producing enterprises, as well as to develop practical recommendations to minimize the harmful effects of subsoil users. Field and laboratory research methods were used in the work. Assessment of the state of groundwater at the Kokzhide deposit consists in a comparative analysis and processing of the results obtained during laboratory studies of water samples, taking into account the data of field route observations of the territory of the studied object, made in October 2019. In addition, the average intensity of pollution by oil products and the degree of natural protection of groundwater were chosen as the main criteria for assessing the ecological state of groundwater. The results of the research have shown increased concentrations of oil products in the content of the underground water. A comparative analysis of the obtained data shows the correlation of the content of oil products with the depth of observation wells. The greatest excess of the maximum permissible concentration of oil products in groundwater was observed mainly in the north-western part of the territory of the Kokzhide groundwater field, in the areas of intensive production of hydrocarbons. The high content of phenols in groundwater is the result of the impact of the activities of oil producing enterprises, as a result of which oil products, which contain phenol, are introduced into the aquifers. At the same time an increase in the content of total iron in the Kokzhide underground waters was found, which may result from the processes of oxidation and corrosion of well filters and casing pipes. Moreover, the assessment of the natural protection intensity of the groundwater field it has shown that the natural hydrogeological conditions of the site give rise to a high risk of introducing oil products into the aquifers, resulting in the formation of extensive pollution.

Authors: Choudhury K.B. Dev , Sarma M.
Published: March 2022

Background: To have a better understanding of the lympho glandular complexes (LGC) along with the histoarchitecture of large intestine and associated M cells, the proposed study have been undertaken.
Methods: Present study was conducted on 12 (twelve) numbers of apparently healthy weaned crossbred piglets of 3 to 4 months irrespective of sex. After humane sacrifice of the animals with the approval of institutional animal ethics committee, the representative tissue samples were collected preserved, processed and stained as per standard methods of Luna (1968). Result: Columnar cells predominated the follicle associated epithelium (FAE) and the crypts. M cells were recorded in the follicle associated epithelium as well as in lower crypt epithelium in toluidine blue stained ultra thin sections. M cells were observed with intraepithelial lymphocyte and basally placed euchromatic nucleus. In the colon and rectum of crossbred pigs the lympho glandular complex (LGC) typically consisted of a pore like depression on surface epithelium from which extensions of mucosal glands passed through the circular gap into lamina muscularis mucosae. The lymphatic aggregation of LGC in the lamina propria and tunica submucosa showed three distinct zone viz. follicle, interfollicular area and dome area and distinct FAE could be appreciated. The epithelium lining the solitary lymphatic nodule (SLN) showed (Periodic acid-Schiff) PAS positive reaction. The mucous substance showed strong reaction in the gland in LGC and the FAE epithelium the number of goblet was less. The LGC was formed by aggregation of lymphoid follicles with invagination of crypt gland inside the follicle in the tunica sub mucosa. The follicle associated epithelium devoid of goblet cells were observed on the LGC with interspersed of diffuse migrating lymphocytes in the lamina propria. In the LGC, secondary follicle with interfollicular area was appreciated. In mesenteric lymph node the secondary follicles with inner germinal centre and outer corona could be seen in cortico medullary area. Meshwork of reticular fibers was abundantly present around the crypts in the lamina propria and in the pore like depression of LGC and around the secondary follicle. Collagen fibers could be seen surrounding the LGC and glands. Scanty collagen fibres were observed in the inter-follicular glands. Innervations of nerve fibre was observed around the lymphoid follicle and penetrating the LGC. The mucosal glands were PAS positive.
