Globalna pandemija prouzrokovana virusom COVID-19 bitno je utjecala na poslovanje u visokoškolskim bibliotekama u cijelom svijetu, a cilj ovoga istraživanja je utvrditi kako su javne visokoškolske biblioteke u Federaciji Bosne i Hercegovine prilagodile i/ili redefinirale svoje bibliotečko-informacijske usluge pandemijskim okolnostima rada. Za potrebe prikupljanja takvih podataka, anketirani su samo bibliotekari/ke onih javnih visokoškolskih biblioteka koje imaju kontakt (e-mail) na web stranici fakulteta / akademije / univerziteta, a samo istraživanje, koje je kvantitativne prirode, realizirano je korištenjem posebno kreiranog anketnog upitnika, upotrebom Google Forms, u junu 2021. godine. Od ukupno 47 mapiranih biblioteka, 26 biblioteka je sudjelovalo u ispunjavanju ankete (ukupno 55,3%). U ovom istraživačkom radu, koji je prvi ove vrste u Federaciji Bosne i Hercegovine, donose se pristupi visokoškolskih biblioteka koje, za razliku od visokoškolskih biblioteka iz razvijenih evropskih zemalja, djeluju u vrlo specifičnim uslovima koje, prije svega, karakteriziraju ograničeni i nedovoljni budžeti za nabavku građe, ali i nedostatak osnovne IT opreme. Rezultati pokazuju da su uprkos zatečenim, često neodgovarajućim elementarnim uslovima rada, visokoškolski bibliotekari ulagali izvjesne napore orijentirane ka zadovoljenju informacijskih potreba korisnika tokom svjetske zdravstvene krize, ali i da je pandemija naglasila hitnu potrebu digitalne transformacije istraživanjem obuhvaćenih visokoškolskih biblioteka. = The global pandemic caused by the COVID-19 virus has significantly affected library processes and procedures in academic libraries worldwide, and the aim of this study is to determine how public academic libraries in the Federation of Bosnia and Herzegovina (FB&H) have adapted and/or redefined their library and information services to pandemic circumstances. For the purposes of collecting such data, only librarians of those public academic libraries who have contact information (e-mail) displayed on the faculty / academy / university website were surveyed. The research itself, which is of a quantitative nature, was realized by using a survey questionnaire, which was created on Google Forms, in June 2021. Out of a total of 47 mapped libraries, 26 academic libraries participated in the survey (response rate of 55.3%). This research paper, which is first of its kind in Federation of Bosnia and Herzegovina, brings approaches of academic libraries which, unlike academic libraries from developed European countries, operate in very specific circumstances which are primarily characterized by limited and insufficient budgets for procurement of collections but also basic IT equipment. Results showed that despite the found inadequate elementary working conditions, academic librarians made certain efforts aimed towards meeting the information needs of library users during the world health crisis, but also that the pandemic emphasized the urgent need for digital transformation of surveyed academic libraries.

Surgically perforated stomach (since direct injury in rats until persisting defect and huge adhesions (day 1, day 7)) fairly represent an unresolved cytoprotection issue, and thereby, we focused resolving of the immediate triad, particular vascular failure (vessels 'disappear'/empty), prolonged bleeding, debilitated defect large widening. Agents (mg/kg) or saline (controls) were given at 1 min post-injury as an abdominal bath (10 ml/rat throughout 2 min). Within 1 - 15 min post-injury period, with cytoprotective BPC 157 (0.01 μg), the rapidly restored vessels 'run' (vessels filled/reappeared) toward the perforated defect, and there is less bleeding, and defect contraction; advanced perforated lesion healing (day 1) to complete healing (day 7), and less adhesions. With pantoprazole (10 mg), early (vessels (worsening), bleeding (prolongation), defect (attenuated widening)) effect means eventual lesions and adhesions severity as in controls. Ranitidine (10 mg) early effect (vessels (improvement), bleeding (less bleeding), defect (eliminated widening, defect not changed)) means final lesions attenuation, but not complete healing, less adhesions. L-NAME (5 mg) early (vessels worsening, less bleeding, attenuated defect widening) and final (lesions aggravation, more adhesions) effect, versus L-arginine (100 mg) early (vessels improvement, more bleeding, attenuated defect widening) and final (lesions attenuation, less adhesions) effect, combined few simultaneously occurring nitric oxide (NO)-system distinct processes. Finally, in the stomach tissue surrounding defect, increased malondialdehyde (MDA)- and decreased NO-values, BPC 157 reversed to the normal healthy values, and mRNA expression studies (Cox2, VEGFa, Nos1, Nos 2, Nos3, Nkap (NF-kappa-B-activating protein gene)), done at that very early post-perforation-time, indicate a way how BPC 157 may act beneficially in the perforated stomach lesion throughout NO- and prostaglandinds-system.

Abstract The importance of the English language in a contemporary globalized world leads to borrowing of English words into many languages, including Bosnian. The current research investigates the knowledge of the original English written form and translation of the English-origin youth-related words (anglicisms) among young native speakers of Bosnian. The study included 345 Bosnian and Herzegovinian high school students, both males and females, in 9 cities. The findings revealed that the usage of Anglicisms among Bosnian youth is not so frequent and that young people in Bosnia and Herzegovina are more familiar with the original written forms than with their translation/synonyms in the Bosnian language. Moreover, knowledge of these two forms of anglicisms shows variation only relative to a grade in English, while gender and age were found to be irrelevant. Also, no difference was shown in the knowledge of anglicisms in different fields: sports, fashion, and science and technology. Further research is recommended to study these and other youth-related anglicisms on a larger population sample.

Abstract In the process of designing a system, it is necessary to identify potential threats to that system and to include appropriate countermeasures. The process that helps in finding problems in the initial phase of the system design is the threat modeling. Creating a threat model consists of several steps and there are many tools that can help in automating the procedure. This article deals with the threat analysis for an Ambient Assisted Living (AAL) system based on Wireless Sensor Network (WSN), whose main function is to provide information for carers in order to provide the best possible help to the elderly and disabled. We have identified and analysed 99 potential threats to the considered system, where Denial of Service (DoS) resulted in being the most represented class of threats. After conducting the threat assessment, the obtained results showed that the majority of threats are high-risk and justified the use of threat modeling in the design phase, since they can be utilized in further system development stages.

O amendoim é uma cultura agrícola amplamente conhecida no Brasil. O consumo in natura é o principal meio de aproveitamento da produção. Originário da América do Sul é uma das oleaginosas mais cultivadas em todo mundo, em razão da grande variabilidade nas formas de consumo, sabor e adaptabilidade de produção em áreas tropicais e subtropicais. O objetivo do presente trabalho foi avaliar o desempenho das características agronômicas de crescimento e produtividade de cinco acessos de amendoim sob adubação orgânica. O trabalho foi conduzido no câmpus das Auroras da Unilab, entre abril e julho de 2018. Foi utilizado um delineamento estatístico de blocos casualizados (DBC) com cinco tratamentos e seis repetições. Foram analisadas as características agronômicas: Dias de Emergência (DE), Altura das Plântulas (AP), Números de Ramos, Número de Vagens por Planta (NVP), Número de grãos por Planta (NGP), Peso de massa fresca (PMF), Peso de Massa Seca (PMS) e Peso de 100 grãos (P100G). Os dados foram submetidos à análise de variância em delineamentos de blocos casualizados com três repetições. Os quadrados médios foram comparados pelo teste F e as médias pelo teste de Tukey a 5%. Os acessos Unilab 130 e Unilab 138 destacaram-se em peso e produção de vagens sendo bons genótipos de porte rasteiro. Unilab 107 e 124 situaram-se como intermediários aos demais acessos em relação à produção e podem ser considerados para produção desde que atendidas suas exigências de cultivo. Unilab 130 apresenta-se como um bom genótipo a ser utilizado como genitor em programas de melhoramento.

The development of the internet of things (IoT) and smart cities, combined with the widespread usage of cooperative or independent air traffic surveillance systems such as automatic dependent surveillance-broadcast (ADS-B) bring about novel deployment paradigms in air-ground integrated vehicular net-works (AGVN). However, compared with the evolutional physical layer advancing, the communication protocols such as TCP/IP protocol, which are listed on the top of communication protocol stacks, have relatively constricted developments due to their fixed frameworks. The most obvious manifestation of this trend is that these protocols can hardly extend interfaces to maximize the benefits brought by bottom layer upgrades. In view of the above problems, in this paper, we propose a novel handover strategy based on side information of the ADS- B for AG VN. Firstly, a practical scheme of combination between TCP/IP protocol and ADS-B, which is implemented in the Network simulation, version-3 (ns-3), is proposed to adapt the AGVN handover tasks. Secondly, the configuration, timing sequence and parameters, as well as hand over strategies of the scheme are proposed in detail with the modules called by ns-3 simulator. Finally, the experimental results are provided to validate the handover strategies.

In this paper, a channel state information (CSI) feedback method is proposed based on deep transfer learning (DTL). The proposed method addresses the problem of high training cost of downlink CSI feedback network in frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) systems. In particular, we obtain the models of different wireless channel environments at low training cost by fine-tuning the pre-trained model with a relatively small number of samples. In addition, the effects of different layers on training cost and model performance are discussed. Furthermore, a model-agnostic meta-learning (MAML)-based method is proposed to solve the problem associated with large number of samples of a wireless channel environment required to train a deep neural network (DNN) as a pre-trained model. Our results show that the performance of the DTL-based method is comparable with that of the DNN trained with a large number of samples, which demonstrates the effectiveness and superiority of the proposed method. At the same time, although there is a certain performance loss compared with the DTL-based method, the MAML-based method shows good performance in terms of the normalized mean square error (NMSE).

This paper proposes an unmanned aerial vehicle (UAV)-aided full-duplex non-orthogonal multiple access (FD-NOMA) method to improve spectrum efficiency. Here, UAV is utilized to partially relay uplink data and achieve channel differentiation. Successive interference cancellation algorithm is used to eliminate the interference from different directions in FD-NOMA systems. Firstly, a joint optimization problem is formulated for the uplink and downlink resource allocation of transceivers and UAV relay. The receiver determination is performed using an access-priority method. Based on the results of the receiver determination, the initial power of ground users (GUs), UAV, and base station is calculated. According to the minimum sum of the uplink transmission power, the Hungarian algorithm is utilized to pair the users. Secondly, the subchannels are assigned to the paired GUs and the UAV by a message-passing algorithm. Finally, the transmission power of the GUs and the UAV is jointly fine-tuned using the proposed access control methods. Simulation results confirm that the proposed method achieves higher performance than state-of-the-art orthogonal frequency division multiple-access method in terms of spectrum efficiency, energy efficiency, and access ratio of the ground users.
