Authors: Dorocki Sławomir , Jastrzębski Jan Paweł
Published: March 2021

Modern biotechnology is widely regarded as information technology, a new wave of knowledge-based economy. It is one of the key technologies of the 20th century, with potentially a versatile range of applications, such as healthcare, agriculture and industrial processes. Simultaneously, biotechnology and pharmacy are the strongest fields in the currently funded basic research which contributes to progress in other sciences.According to the European Parliament’s report “Life sciences and biotechnology – A Strategy for Europe”, it is taken for granted that modern biotechnology offers unique opportunities of satisfying many human needs. Biotechnology could thus serve the European Union as a great contribution to the achievement of its policy objectives of economic growth and job creation, public health, environmental protection and sustainable development.In the following years, life sciences and biotechnology industry could potentially become the major areas of science, industry and employment and could improve the quality of life through innovative medical applications, upgrading of industrial bases of Europe, and better environment.This article aims at presenting regional differences in the development of biotechnology in Europe. Delimitation of regions will take place both on the basis of academic achievement in the field and the location of the biotechnology industry in Europe. An attempt will also be made to link the development of biotechnology with other markers of socio-economic regions of Europe.

The coal mining industry in Poland belongs to the branches of industry currently breaking down. It is expressed by the liquidation of mines, whose number in 1989 equalled 70, while in 2010 – only 29; it is also visible in the steady decrease of coal extraction, from 177 million tonnes in 1989 to 77 million tonnes in 2009, whereas employment dropped from 415.7 thousand to 112 thousand, respectively. The decrease in extraction is connected with the process of transformation of the Polish economy and the necessity to adapt to the requirements imposed by the European Union, which required Poland to limit its production of electrical energy from coal. In this context, the situation of the coal mining industry is especially difficult. A question arises, what activities the department of mining has been undertaking in order to cope with these challenges. The article concentrates on innovative activities conducted by the mining industry. They have been presented in their organizational and technological spheres, including the main businesses functioning in the trade, namely Kompania Węglowa, consisting of 15 mines, Katowicki Holding Węglowy, comprising 4 mines, and Jastrzębska Spółka Węglowa, which consists of 5 mines, as well as the remaining mines functioning independently or within structures of other concerns. Innovative activities in the scope of branch management and organization of sales are described. Innovation in terms of technology consists in the introduction of new products, implementation of modern machinery and equipment for exploitation, as well as the monitoring of coal extraction and minimizing the negative impact on the environment.

Perspektywy wykorzystania gazu łupkowego w energetyce Unii Europejskiej
Authors: Pach-Gurgul Agnieszka
Published: March 2021

W dyskusjach na temat międzynarodowych rynków gazu oprócz niepewności związanejze zmianami popytu na gaz dominuje kwestia jego wydobycia ze złóż niekonwencjonalnych, w tymz łupków. Pozyskanie i wykorzystanie gazu z łupków w Stanach Zjednoczonych istotnie wpłynęło bowiemna gospodarkę tego kraju i spowodowało spadek jego cen, obniżenie kosztów produkcji orazwzrost konkurencyjności gospodarki i wiele innych efektów określanych mianem „rewolucji łupkowej”.Obecnie w Unii Europejskiej trwa dyskusja nad wykorzystaniem gazu łupkowego w unijnej energetyce.Z jednej strony przytaczane są pozytywne efekty rewolucji łupkowej w Stanach Zjednoczonychi Kanadzie, możliwość zmniejszenia uzależnienia od importu gazu z Rosji a przy tym zwiększeniaswojego bezpieczeństwa energetycznego, z drugiej strony przeciwstawiane są potencjalne zagrożeniadla środowiska naturalnego, w tym możliwości zatrucia wód gruntowych.Artykuł jest próbą znalezienia odpowiedzi na następujące pytania badawcze: Czy w krajach Unii Europejskiej o potencjalnych zasobach gazu łupkowego nastąpi jego wykorzystaniei w jakim zakresie?– Jakie efekty „europejska rewolucja łupkowa” może przynieść dla poszczególnych krajów UniiEuropejskiej oraz całego ugrupowania integracyjnego? Czy Unia Europejska włączy wykorzystanie gazu łupkowego w reguły wspólnej polityki energetycznej,czy decyzje w tej kwestii podejmować będzie suwerennie każdy kraj?Wydaje się, iż gaz łupkowy jest również szansą dla unijnej energetyki, jednakże perspektywy jego eksploatacjii wykorzystania zależeć będą przede wszystkim od woli państw członkowskich, ich miksów energetycznych oraz od stanowiska Unii Europejskiej w tej kwestii.

The structure of information streams defines the social-psychological atmosphere in a district, a city or a region. The main data carrier are people. Thus, the structure and intensity of flows of people is a defining factor of a social-psychological background for development of territories. A set of historical examples prove it. Will depression, or growth and development reign in the territory? Will the development have a sequenced character, or will criminal tendencies start to prevail? The nature of development of territories depends considerably on how flows of information will be organized..

Wpływ światowego kryzysu gospodarczego na kształtowanie polityki regionalnej w Polsce
Authors: Rubacha Barbara
Published: March 2021

Polityka regionalna jest częścią polityki rozwoju kraju. Na skutek kryzysu władze rządowe w wielu krajach, w tym w Polsce, wprowadziły zmiany w swojej polityce regionalnej poprzez kierowanie dodatkowej pomocy dla regionów słabszych strukturalnie. Celem referatu jest pokazanie, jak światowy kryzys gospodarczy wpłynął na zmiany w formułowaniu problemów i wyznaczaniu nowych celów oraz proces realizacji polityki regionalnej. W 2008 roku rząd RP przystąpił do prac nad opracowaniem modelu polityki regionalnej, dostosowanego do obowiązującej polityki spójności Unii Europejskiej. Podstawą tego założenia była nowelizacja ustawy z dnia 7 listopada 2008 roku o zmianie niektórych ustaw w związku z wdrażaniem funduszy strukturalnych i Funduszu Spójności. Przeanalizowano także wpływ funduszy europejskich na gospodarkę polskich regionów. Programy operacyjne Unii Europejskiej są głównym źródłem finansowania i stanowią podstawowy mechanizm realizacji polityki regionalnej w Polsce. Stopień wrażliwości regionu na kryzys oszacowano za pomocą wskaźników: PKB na mieszkańca, stopy bezrobocia i zatrudnienia. Zauważyć można, że charakter polityki regionalnej skupionej na zasadach równości terytorialnej zmienił się na rzecz pobudzania wzrostu gospodarczego oraz natężenia konkurencji w skali regionalnej. Na potrzeby niniejszego opracowania wykorzystano analizę raportów Ministerstwa Rozwoju Regionalnego, raportów Ministerstwa Gospodarki, raportów EoRPA (European Regional Policy Research Consortium) oraz danych Eurostat i GUS. Główną metodą badawczą była analiza opisowa oraz analiza materiałów archiwalnych i statystycznych.

Authors: Ćwikła Mateusz
Published: March 2021

Udział odnawialnych źródeł energii (OZE) w Krajowym Systemie Elektroenergetycznym (KSE) od kilku lat systematycznie wzrasta. W Polsce energia ze źródeł odnawialnych obejmuje energie: promieniowania słonecznego, wiatru, wody, zasobów geotermalnych oraz energię wytworzoną z biopaliw stałych, biogazu i biopaliw ciekłych, a także energię otoczenia pozyskiwaną przez pompy ciepła. W niniejszej pracy została przedstawiona aktualna sytuacja na rynku energii elektrycznej, z uwzględnieniem mocy zainstalowanej. Zasadniczym celem artykułu było określenie roli odnawialnych źródeł energii w funkcjonowaniu KSE wraz ze wskazaniem potencjałów technicznych i realnych potencjałów rynkowych OZE dotyczących możliwości wykorzystania energii elektrycznej. W Polsce w ostatnich latach dokonał się znaczący postęp w zakresie efektywnego wykorzystania energii. W unijnej perspektywie finansowej 2014–2020 zapisano w celach wspieranie przejścia na gospodarkę niskoemisyjną we wszystkich sektorach. Promowanie efektywności energetycznej i użycia OZE w przedsiębiorstwach i budynkach mieszkaniowych dotyczy zmniejszenia strat energii, ciepła i wody oraz kompleksowej modernizacji energetycznej budynków i obiektów.

Kryzys gospodarczy, który wystąpił w Polsce w latach osiemdziesiątych ubiegłego wieku, doprowadził do zupełnego rozpadu więzi ekonomicznych i politycznych ukształtowanych po II wojnie światowej. Sytuacja ta pobudziła gwałtowane procesy przemian ustrojowych, a następnie spowodowała konieczność głębokich przekształceń i reform. Wyrazem tych przemian było przejście od centralnego systemu sterowania gospodarką narodową do gospodarki rynkowej (Kamińska 1996, s. 8)...
Zróżnicowanie światowej przestrzeni przemysłowej w świetle koncentracji siedzib zarządów wiodących korporacji

W procesie nasilających się procesów globalizacji podstawową rolę odgrywają wiodące korporacje, które poprzez różnorodne systemy sieciowych powiązań przestrzenno-produkcyjnych organizują światową przestrzeń gospodarczą zgodnie ze swoimi regułami rozwoju. Przejawia się to w określonych kierunkach i nasileniu powiązań w zakresie: zaopatrzenia surowcowego, dostaw kooperacyjnych, rynków zbytu, przepływów technologii, kapitału oraz decyzji. Działania te prowadzą do utrwalania i pogłębiania istniejących rynków oraz utrwalania lokalizacji działalności poszczególnych oddziałów, a także poszukiwania nowych miejsc lokalizacji i nowych rynków zaopatrzenia oraz zbytu gotowych produktów …
Delokalizacja przedsiębiorstw – przejaw światowej samoregulacji
Authors: Kostrubiec Beniamin
Published: March 2021

Kapitalistyczny system gospodarczy opiera się na umiędzynarodowieniu ekonomii. Polega na poszukiwaniu zewnętrznych chłonnych rynków zbytu i możliwości produkcji jak najmniejszymi kosztami. Dawniej taka dążność była bodźcem do organizowania podbojów kolonialnych. Obecnie światowy pokojowy porządek ekonomiczny i logika finansowa jest odmienna, stanowi jednak powód zaburzeń procesów produkcyjnych. Według definicji Funduszu Monetarnego, globalizacja to „wrastająca gospodarcza współzależność krajów świata, spowodowana wzrostem woluminu i rodzajów transgranicznych transakcji dóbr i usług, międzynarodowych przepływów kapitałów, z równoczesną przyspieszoną i uogólnioną dyfuzją technologii”. Świat wszedł w erę gospodarki globalnej. Globalizacja wzbudza kontrowersje, w równym stopniu dzieli, jak i jednoczy. Przedsiębiorstwa skłaniają się do delokalizacji produkcji do krajów o znaczącym wzroście ekonomicznym i względnie słabych kosztach produkcji. Dokonują tego po uprzednim rozpoznaniu chłonności rynku, kondycji społeczno-ekonomicznej istniejącej w krajach goszczących. Globalizacji towarzyszy wynarodowienie końcowego produktu, uniemożliwiające jego „narodową” identyfikację...

Four-dimensional digital subtraction angiography for exploration of intraosseous arteriovenous fistula in the sphenoid bone
Authors: Ishibashi Toshihiro , Maruyama Fumiaki , Kan Issei , sano Tohru , Murayama Yuichi
Published: March 2021

Background:

Intraosseous arteriovenous fistula (AVF) is a rare clinical entity that typically presents with symptoms from their effect on surrounding structures. Here, we report a case of intraosseous AVF in the sphenoid bone that presented with bilateral abducens palsy.

Case Description:

A previously healthy man presented with tinnitus for 1 month, and initial imaging suspected dural AVF of the cavernous sinus. Four-dimensional digital subtraction angiography (4D-DSA) imaging and a three-dimensional (3D) fused image from the bilateral external carotid arteries revealed that the shunt was in a large venous pouch within the sphenoid bone that was treated through transvenous coil embolization. His symptoms improved the day after surgery.

Conclusion:

This is a case presentation of intraosseous AVF in the sphenoid bone and highlights the importance of 4D-DSA and 3D fused images for planning the treatment strategy.
Majorana fermions and non-locality
Authors: Campbell Earl T. , Hoban Matty J. , Eisert Jens
Published: March 2021

Localized Majorana fermions emerge in many topologically ordered systems and exhibit exchange statistics of Ising anyons. This enables noise-resistant implementation of a limited set of operations by braiding and fusing Majorana fermions. Unfortunately, these operations are incapable of implementing universal quantum computation. We show that, regardless of these limitations, Majorana fermions could be used to demonstrate non-locality (correlations incompatible with a local hidden variable theory) in experiments using only topologically protected operations. We also demonstrate that our proposal is optimal in terms of resources, with 10 Majorana fermions shown to be both necessary and sufficient for demonstrating bipartite non-locality. Furthermore, we identify severe restrictions on the possibility of tripartite non-locality. We comment on the potential of such entangled systems to be used in quantum information protocols.
Unextendible mutually unbiased bases from Pauli C\classes
Authors: Mandayam Prabha , Bandyopadhyay Somshubhro , Grassl Markus , Wootters William K.
Published: March 2021

We provide a construction of sets of $d/2+1$ mutually unbiased bases (MUBs) in dimensions $d=4,8$ using maximal commuting classes of Pauli operators. We show that these incomplete sets cannot be extended further using the operators of the Pauli group. Moreover, specific examples of sets of MUBs obtained using our construction are shown to be {\it strongly unextendible}; that is, there does not exist another vector that is unbiased with respect to the elements in the set. We conjecture the existence of such unextendible sets in higher dimensions $d=2^{n} (n>3) $ as well.} {Furthermore, we note an interesting connection between these unextendible sets and state-independent proofs of the Kochen-Specker Theorem for two-qubit systems. Our construction also leads to a proof of the tightness of a $H_{2}$ entropic uncertainty relation for any set of three MUBs constructed from Pauli classes in $d=4$.
Azobispyrazole Family as Photoswitches Combining (Near-)Quantitative Bidirectional Isomerization and Widely Tunable Thermal Half-Lives from Hours to Years
Authors: He Yixin , Shangguan Zhichun , Zhang Zhao-Yang , Xie Mingchen , Yu Chunyang , LI Tao
Published: March 2021

Azobenzenes are one of the most attractive class of molecular photoswitches. In recent endeavors of molecular design, replacing one or both phenyl rings by heteroaromatic ones is emerging as a strategy to expand the molecular diversity and to access improved photoswitch properties. However, the currently available heteroaryl azo switches generally show limitations on E ⇆ Z photoisomerization yields and/or Z-isomer stability. Here we report a family of azobispyrazoles as new photoswitches, which combine (near-)quantitative bidirectional photoconversions and widely tunable Z-isomer thermal half-lives (t1/2) from hours to years. A visible-light-activated photoswitch is also obtained. Systematic experimental and theoretical investigations reveal the different geometric and electronic structures of azobispyrazoles from those of phenylazopyrazoles, overcoming the conflict existing in the latter between effective photoconversion and Z-isomer stability. Our work shows the great potential of azobispyrazoles in developing photoresponsive systems and can inspire the rational design of new photoswitches making use of bis-heteroaryl azo architecture.
On the Thermodynamic Control of Ring Opening of 4-Substituted 1,3,3-Tris-Carbethoxycyclobutene and the Role of the C-3 Substituent in Masking the Kinetic Torquoselectivity. An alternate reaction pathway
Authors: Yadav Veejendra , Prasad Dasari L V K , Yadav Arpita , Rao Maddali L N
Published: March 2021

The predominant transformations of 4-methyl- and 4-phenyl-1,3,3-tris-carbethoxycyclobutenes to s-trans-trans-1,1,3-tris-carbethoxy-4-methyl- and 4-phenyl-1,3-butadienes, respectively, proceed through pathways entailing heterolytic cleavage of the sC3C4 bond rather than the usual four-electron conrotatory ring opening following the rules of torquoselectivity. The adventitious or in situ generated halogen acid from CDCl3 catalyzes the reaction of 4-methyl-1,3,3-tris-carbethoxycyclobutene by protonation of one of the two ester groups on C3 and, thereby, weakening the sC3C4 bond to allow its heterolytic SN2 cleavage by the chloride ion. This is followed by cisoid→transoid isomerization and loss of the elements of the halogen acid to form the products. In the Lewis acid-catalyzed reaction of 4-phenyl-1,3,3-tris-carbethoxycyclobutene in CH2Cl2, coordination of the Lewis acid with one of two ester groups on C3 is followed by heterolytic cleavage of the sC3C4 bond. The resultant species subsequently undergoes cisoid→transoid isomerization before losing the Lewis acid to form the products.

Published: March 2021

Das diferentes preocupações sobre as quais repousam a atenção das pesquisas que temos desenvolvido no âmbito de um grupo de estudo em Educação Matemática, uma delas, de modo particular, diz respeito ao desenvolvimento da Criatividade em contextos de aulas com Modelagem Matemática. Nesta perspectiva, neste ensaio temos como objetivo estabelecer uma aproximação teórica entre a Modelagem Matemática, tomada na perspectiva da Educação Matemática, e a Criatividade, principalmente no que diz respeito aos elementos do processo criativo. Neste sentido, apresentamos nosso entendimento sobre Modelagem Matemática e sobre Criatividade; empreendemos uma revisão de literatura sobre Modelagem e Criatividade e, por último, apresentamos uma aproximação entre elementos do processo criativo e a Modelagem Matemática, o que chamamos de confluências. Esse movimento permitiu-nos apontar, dentre outras considerações, que aspectos do processo criativo tais como liberdade, investigação, mobilização de ações cognitivas e metacognitivas dos estudantes, são também aspectos destacados na literatura para as atividades de Modelagem Matemática como contribuições para o ensino e para a aprendizagem.
Case Study: A Wellness Workplace Policy and HIV/AIDS Policy for Zambia’s Ministry of Tourism and Arts
Authors: A Breckon Denise , L. Ammons Deanna , Badi Frank , Barker Walsh Chelsea
Published: March 2021

The Ministry of Tourism and Arts (2018) identified an overall goal of utilizing Zambia’s natural and cultural resources as a tourism driver to increase economic growth for the country. However, the industry has experienced problems with attrition, productivity, and high mortality rates of wildlife police officers (WPOs) which negatively affects the ability to protect the wildlife and natural resources that drive the tourism industry. A systematic review of the evidence was conducted in support of the Ministry of Tourism and Arts (MOTA) to identify the key components of a workplace wellness and HIV/AIDS program to reduce the attrition and mortality of the WPOs. The findings from the review indicate the essential components of a wellness workplace and HIV/AIDS policy can be bucketed into four categories: (a) program design; (b) program growth; (c) disease management and prevention; and (d) program evaluation. Findings also indicate that wellness programs have a positive correlation with absenteeism, job satisfaction, job performance/productivity, employee turnover, and return on investment (ROI). However, management involvement and support to resource a program and reduce the stigma associated with it are necessary for its success. This case study presents evidence-based recommendations to assist the MOTA with the development and implementation of an effective Wellness Workplace Policy focusing on HIV/AIDS, other communicable and noncommunicable diseases, addiction, and mental health support. Recommendations included the formation of a workplace wellness committee, development and communication of the wellness program, engagement through employee forums, increased training for leadership, and the involvement of stakeholders as program advisors.

Authors: Basnina Tatyana , Valitova Lilia , Sheresheva Marina
Published: March 2021

. Amid the COVID-19 pandemic, the need for effective government decisions in the field of public health is becoming increasingly urgent. The article discusses the issues of the Russian health resort industry management as a complex system that plays a key role in the preservation and qualitative improvement of the country’s human potential. The concepts of sustainable development, human potential development, rehabilitation medicine and the system-based approach in management constitute the methodological basis of the research. The methods of analysis, synthesis, systematization and statistical observation are applied. We juxtapose the official statistical data that reflect the state and trends in the health resort industry’s development during the pre-pandemic period. The study identifies the challenges in the health resort industry management and develops the ways to create conditions for qualitative shifts in the field of public well-being and health, and human potential development. The authors substantiate the need to create a modern health resort industry in Russia with a new rest / treatment infrastructure, a regulatory and legislative framework, and information systems for data exchange. Solving this problem requires fundamental changes in the fields of finance and taxation, as well as the training of management staff. We conclude that amid the pandemic, along with serious negative effects, there also emerge incentives to reconstruct the health resort system, which should be founded on long-term government policy measures and system-based management decisions.

Published: March 2021

This article explores the potential factors that might be influencing the length and tone of the discourse of the IBEX35 presidents’ letters to shareholders. It also provides an analysis of their content. The methodological framework of the research relies on the impression management theory, that is, how companies want to present themselves, in a way that contributes to their goals. The research uses an automatic process of textual analysis, through R and Voyant Tools. For tone and length analysis, we used a total of 187 letters corresponding to the years 2013–2018, and for content analysis, a larger sample of 321 letters corresponding to the years 2008–2018. According to the research findings, there was a greater positive tone when the profits after taxes decreased and when the directors’ remuneration increased with respect to the previous year. Regarding content, the research shows that there are differences between non-financial and financial companies. In conclusion, our findings, which show that in certain situations the tone of discourse changes, are supported by and contribute to impression management theory. The study may be of interest to shareholders to better understand the content of the chairpersons’ letters.

Authors: Andono Pulung Nurtantio , Rachmawanto Eko Hari
Published: March 2021

Batik as one of Indonesia's cultural heritages has various types, motifs and colors. A batik may have almost the same motif with a different color or vice versa, therefore it requires a classification of batik motifs. In this study, a printed batik was used with various coastal batik motifs in Central Java. The algorithm for classification is selected Support Vector Machine (SVM) with feature extraction of the Gray Level Co-Occurrence Matrix (GLCM) and Local Binary Pattern (LBP). SVM has the advantage of grouping data with small amounts and short operation times. GLCM as an extractive feature for recognizing batik textures and LBP was chosen to do spot pattern recognition. In the experiment, we have used 160 images of batik motifs which are divided into two, namely 128 training data and 32 testing data. The accuracy results obtained from the SVM, GLCM and LBP algorithms produce 100% accuracy in polyniomial, linear and gaussian kernels with distances at GLCM 1, 3, and 5, where at a distance of 1 linear kernel is 78.1%, gaussian 93.7%. At a distance of 3 linear kernels 75%, gaussian 87.5% and at a distance of 5 linear kernels 84.3%, gaussian 87.5%. In the SVM and GLCM algorithms the resulting accuracy is at a distance of 1 with a polynomial kernel 96.8%, linear 68.7%, and gaussian 75%. At distance 3, the polynomial kernel is 100%, linear 71.8%, and gaussian 78.1%, while for distance 5, the polynomial kernel is 87.5%, linear 75%, and gaussian 81.2%.

Published: March 2021

Malaria is a disease caused by the Plasmodium parasite that transmitted by female Anopheles mosquitoes. Malaria can become a dangerous disease if late have the medical treatment. The late medical treatment happened because of misdiagnosis and lack of medical staff, especially in the countryside. This problem can cause severe malaria that has complications. This study creates a system prediction to classify the severe malaria disease using Classification and Regression Tree (CART) method and the probability of malaria complication using Naïve Bayes method. The first step of this study is classifying the patients that have symptom are infected severe malaria or not based on the model that has been built. The next step, if the patient classified severe malaria then the data predicted if there any probability of complication by the malaria. There are 8 possibilities of complication malaria which are convulsion, hypoglycemia, hyperpyrexia, and the combinations of these four. The first step will evaluate by using F-score, precision and recall while the second step will evaluate by using accuracy. The highest result F-score, precision and recall are 0.551, 0.471 and 0.717.

Institutional community-based mangrove management as an alternative to sustainable management of mangrove forests. This study aims to analyze which factors from the institution most play a role in guiding the community in managing mangrove forest resources in relation to forest management units (FMU). Primary data were collected through interviews conducted semi-structured to 26 respondents selected by the purposive sampling method. The snowball method is used to capture information from key figures. Deepening is considered complete if information saturation has occurred which is marked by repetition of the same information. While secondary data, obtained from various libraries. Of the three models of mangrove management institutions, namely the community institution of Pusong Kapal Village (PKV), the community institution of Pusong Telaga Tujoh Village (PTTV), and the Community Forestry (CF-BM) Bina Mufakat institution where the analysis shows that the community institutions of Pusong Kapal Village (PKV) are more flexible as an alternative form of community-based mangrove management institutions, because this institution is able to adapt to the changing social and environmental conditions that continue to occur, the collaboration of management with the government, and the recognition of community rights in the use of mangrove forests. FMU as the management authority at the site level has guaranteed the upholding of the rights of the PKV community as the manager of mangrove forests so that the bundle of rights and incentives obtained in the management of mangrove resources by PKV communities becomes strong.

Objective: To compare the efficacy of probiotics in prevention of necrotizing enterocolitis (NEC) among low birth weight (LBW) preterm neonates. Study Design: Randomized controlled trial. Setting: Department of Pediatric Medicine, Unit-II, Services Hospital, Lahore. Period: September 2019 to February 2020. Material and Methods: A total of 260 LBW preterm neonates were enrolled. All the neonates were allocated to 2 groups with equal number of cases (130 in each group). Group-A was given probiotics whereas placebo was administered in Group-B. All the cases were admitted and follow ups were made up until 7th day. Occurrence of NEC was recorded among both groups. Results: Out of a total of 260 LBW preterm neonates, 142 (54.6%) were male and118 (45.4%) female. Overall, mean age was noted to be 1.48+0.50 days. Table-I shows that there was no statistical difference among neonates of both study groups in terms of age, gestational age and birth weight (p>0.05). Five (3.8%) neonates in Group-A and 14 (10.8%) in Group-B were found to have NEC. Efficacy of treatment in Group-A was significantly higher in comparison to Group-B. Conclusion: Probiotics are effective in the prevention of NEC in preterm LBW neonates. Prophylactic usage of probiotics among preterm neonates is noted to be helpful in avoiding development of NEC.

This study aims to determine the opportunities and challenges faced by diffable entrepreneurs in accessing banking capital. In addition, it is also to find out the extent to which the role of banks provides access to capital for diffable entrepreneurs. The study was a descriptive qualitative study involving blind and disabled disabled entrepreneurs who were members of Persatuan Tuna Netra Indonesia (PERTUNI) DIY, Persatuan Penyandang Disabilitas Indonesia (PPDI) DIY area and Ojek Difa DIY motorcycle taxi. Data collection uses interview, observation and documentation methods. Data analysis is done by collecting data, reducing data, presenting data (data display), and drawing conclusions. The results showed that only a small proportion of blind diffable entrepreneurs had interacted with the banking sector, the rest preferred to interact with other financial institutions such as cooperatives established by PERTUNI and BMT. They chose this because banking services were considered to be quite complicated or lacking in access for blind diffable entrepreneurs. On the other hand, disabled entrepreneurs have often interacted with banking and there are no significant problems in the process of lending bank capital. However, both the disabled and forced entrepreneurs hope there will be an increase in services for diffable entrepreneurs primarily in terms of facilities and infrastructure as well as more diffable-friendly banking service products.Keywords: accesisbility of banking capital, diffable entrepreneurs, economic inclusion

Abstract

      The nuclear structure of 28-40Si isotopes toward neutron dripline has been investigated in framework of shell model with Skyrme-Hrtree-Fock method using certain Skyrme parameterizations. Moreover, investigations of static properties such as nuclear densities for proton, neutron, mass, and, charge densities with their corresponding rms radii, neutron skin thicknesses, binding energies, separation energies, shell gap, and pairing gap have been performed using the most recent Skyrme parameterization. The calculated results have been compared with available experimental data to identify which of these parameterizations introduced equivalent results with the experimental data. For all dynamic properties, sdpf shell model space has been used to generate one body transition density matrix element with SDPFK two body effective interaction. The calculations also reproduced the low and higher-laying 2+ energy level scheme, and reduced transition probability B(E2) for even Si-isotopes.

Published: March 2021

Thin films of CuPc of various thicknesses (150,300 and 450) nm have been deposited using pulsed laser deposition technique at room temperature. The study showed that the spectra of the optical absorption of the thin films of the CuPc  are two bands of absorption one in the visible region at about 635 nm, referred to as Q-band, and the second in ultra-violet region where B-band is located at 330 nm. CuPc thin films were found to have direct band gap with values around (1.81 and 3.14 (eV respectively. The vibrational studies were carried out using Fourier transform infrared spectroscopy (FT-IR). Finally, From open and closed aperture Z-scan data non-linear absorption coefficient and non-linear refractive index have been calculated respectively using He-Ne laser which have beam waist of (24.2 μm), wave-length of (632.8 nm) and Rayleigh thickness was 2.9 mm.
