Authors: Gayen Debayan , Roy Subhajit , Adhurya Sagar , Singhamahapatra Aniruddha , Seal Somapika , Dutta Avik
Published: July 2022

Plumage colouration is important for birds as it helps them in camouflage, mate selection, social signalling and various other physiological and behavioural processes. The most common pigments responsible for colouration are melanins and carotenoids. In a few individuals, colouration is disrupted due to various causes. The most common colour aberrations found in birds are leucism, albinism, melanism, carotenism, schizochroism and dilution whereas xanthochroism is a lesser-known phenomenon. In this article, five records of colour aberrant Coppersmith Barbet Psilopogon haemocephalus are reported. The authors along with the help of citizen scientists observed four individuals with disruptions in plumage colouration from different areas of West Bengal and Assam, India and one from Rajsahi, Bangladesh. Due to the lack of melanins, the birds were mostly yellowish and whitish in colouration with or without some normally coloured feathers on the head and wings. The carotenoid deposition was unaffected in the case of the observed adults and juveniles. These records can be cited as xanthochroistic individuals resulting from leucism. This is the first record of such colour aberration for Coppersmith Barbet from the whole of its distribution range.
Sacred green spaces in semi-urban areas sustain more birds than its adjacent areas: A study from lower Gangetic plains, West Bengal, India
Authors: Sarkar Antara , Mazumdar Subhendu
Published: July 2022

With rapid urban expansion and flourishing real estate sector, remaining green patches in many sub-urban/peri-urban areas are facing immense threat and/or being destroyed. We therefore, explored the avian abundance and richness of green spaces around temples (sacred sites) and compared them with adjoining green spaces without religious places (control sites). The species richness and abundance in sacred sites (12.16 ± 0.65 species; 25.54 ± 1.176 individuals) was significantly higher than control sites (6.31 ± 0.77 species; 20.04 ± 1.4 individuals). The compositions of avian communities of sacred sites were significantly different and the presence of temple positively influenced the species richness. GLMM also revealed that the species richness was positively influenced by the distance to building and tree cover area and not influenced by distance to road, areas of water body, bare land. Our findings indicate that the green spaces around the sacred places have greater avian diversity in semi-urban areas, and could be prioritized for the conservation of avian diversity. Generating local support could be relatively easier due to traditional, religious and/or cultural belief against tree felling around the places of worship.
Distribution and demographic trend of Algerian Nuthatch (Sitta ledanti) population of Mount Babor forest in Babor-Tababort National Park
Authors: Zemouri Mourad , Bougaham Abdelazize Franck
Published: July 2022

The Algerian Nuthatch (Sitta ledanti) is the only bird species endemic to Algeria and it’s a protected species by the Algerian law since 1983. So far, we have no precise information on recent changes in population density as well as the demographic trends of this endangered species in its entire range in the Kabylia of Babors. The population of the species in the Babor-Tababort National Park remains the most abundant, with 275 individuals recorded in 2020. Thirty-eight years after the 1982 census, it multiplied with an annual multiplication rate of (λ) = 1.01 and grew with an annual growth rate of r = 1.36%. The Algerian Nuthatch has been present throughout the Mount Babor forest from 1,300 m altitude to the summit at 2,004 m altitude. The Algerian Nuthatch, in 2020, was more abundant in the mixed cedar forest because this type of forest covers the largest area in Mount Babor. The population of the species in the Mount Babor forest remains isolated that, however, could be connected to the population in the Tababort forest through the setting of an ecological corridor.
A comparative study on the nesting materials used by House Sparrow (Passer domesticus) for Open and Inbox nests
Authors: Mahesh Veerá , Lanka Suseela
Published: July 2022

House Sparrow (Passer domesticus) is a bird species connected to humans, widely distributed in most of the human settlements. They build nests in the crevices of our homes. The recent changes in house design minimized the crevices to build the nests and lead to habitat loss. The nest boxes are the alternative ways to re-establish the decreased House Sparrow population. We investigated the usage of nesting materials by House Sparrow with reference to construction of Open nests and Inbox nests in our study area. Because of its flexible attitude, it utilizes all the available materials for nest construction. In our study area at Jangareddigudem, we have examined about 100 Inbox nests and 40 Open nests. There are around 29 varieties of nesting materials used by Sparrows in the examined Inbox nests and around 27 varieties in the Open nests. Dūrvā grass found to be the major component of all the analyzed nesting materials in both Open and Inbox nests that constituted 43% and 36.5% respectively. The other structural materials such as coconut fibre (3.5%) and broom fibre (6%) were found to be more in Inbox nests. Synthetic fibre was more in Open nests (3.7%). We found significant differences between the Open and Inbox nests with respect to quantum of each nesting material type used, weight of the nests and time taken for nest construction by House Sparrow.
Substrate influences foraging selection by Eurasian Green WoodpeckersPicus viridisin autumn and winter: observations in Hungary over a 20-year period
Authors: Gorman Gerard , Alder Daniel
Published: July 2022

The foraging behaviour and habitat use of the Eurasian Green WoodpeckerPicus viridisat various sites in Hungary over a 20-year period was documented. Detailed observations were recorded on foraging behaviour at hard substrates; in quarries, cliffs and human made structures of brick and stone construction. Using Chi-square tests on the frequency of observations of birds at hard substrates foraging sites, we compared usage during periods of snow cover and those without. Birds were found to be more frequently observed at hard substrates during periods of snow cover because these remained largely free of snow. We supposed that this response was due to invertebrate prey becoming increasingly scarce generally across typical foraging sites, i.e. grasslands and meadows during harsh winter conditions. Accessibility to the alternative sites became important as a source of food because availability of prey was more reliable. Vertical surfaces of hard substrates such as those associated with quarries, cliffs and buildings may be important to sustain Eurasian Green Woodpeckers in periods of snow cover where these provide a valuable foraging resource.

Ratification of the Comprehensive Economic and Trade Agreement (CETA): Towards A New Structure of Political Conflict?
Authors: Maatsch Aleksandra
Published: July 2022

Has the high-profile public opposition to recent EU trade agreements supplanted the traditional socio-economic pattern of competition in European trade policy with a value-driven one? This article draws on new data analysing the outcome of the ratification process of a mixed free trade agreement (CETA) in the European Parliament and in all national parliaments that have so far completed ratification. With help of a logistic regression model analysing the vote-outcome, this article demonstrates that despite high social salience, economic considerations remain prominent. Values (TAN-GAL cleavage) were relevant but played a different role than expected. Against the expectation, green parties associated with the GAL-spectrum voted against CETA demonstrating that party preferences on specific values do not necessarily coincide or generate the same policy preference.
Disentangling the Moral Rightness of Securitization: Data Mining of the Process of Framing and Shaping of Poland-United States Relations
Authors: Kwiatkowska Agnieszka , Chwedczuk-Szulc Karol , Bolechów Bartosz
Published: July 2022

Since the democratic transition, Poland-United States relations have been framed by the Polish authorities as a strategic threat-management tool in the securitization process of Poland’s geopolitical position, particularly concerning the Russian Federation. We analyse the process of securitization regarding Poland-US relations through latent topic modelling of Polish parliamentary speeches in the years 1991–2017. We demonstrate that the discourse on Polish-US relations is heavily dominated by security topics, narrowly understood as military security. Furthermore, even when economic issues are discussed, they are frequently linked to military operations. Based on Floyd’s (2011, 2019) model of the moral rightness of securitization, we argue that the close relationship between securitizing moves (debates on Poland-US relations) and security practices (security events) suggests the basic sincerity of the securitizing actor, while the historical context reflected in the Polish collective memory strongly influences the audience’s frame of reference and strengthens the power of the securitizing actor. However, although the case fulfils Floyd’s (2019) criteria of morally right securitization, we have shown a historical disparity between the scope of securitizing moves with security practices and the existing level of threat. This demonstrates that the securitizing agent has been abusing securitization by exceeding the ‘least harmful option’, particularly due to the large asymmetry of power of the participants in the relationship, the securitization process stretched over a long period and the threat severity varying over time.
Storm Surges Versus Shore Erosion: 21 Years (2000–2020) of Observations on the Świna Gate Sandbar (Southern Baltic Coast)
Authors: Łabuz Tomasz Arkadiusz
Published: July 2022

Based on observations spanning 21 years (2000–2020), the article studies the effects of storm surges on the shore of the Świna Gate Sandbar in the southern part of the Pomeranian Bay (southern Baltic Sea). Impacts of selected maximum storm surges in each year were assessed with respect to morphological data collected on the beach and the foredune. The data included parameters of beach-dune erosion as measured along a beach transect before and after each surge. Differences and trends in the shore erosion were related to the sea level (SL), duration of a storm surge [highest storm sea level (HSL) > 1 m], wind-wave sector and wave run-up. The relationships were explored using a simple correlation analysis. The most serious erosion was observed during the heaviest surges [HSL > 1.3 m above the mean sea level (AMSL)], with a wave run-up higher than 3.2 m AMSL. Such surges occurred at about 2-year intervals. The average SL during a surge was 1.2 m AMSL, with a run-up of 2.6 m AMSL. The beach and the lower part of the shore, below that level, were eroded each year. The heaviest surges resulted in an average 5.2 m and 7.0 m dune retreat on the high-beach-accumulative shore and on the low-beach-erosive shore, respectively. The dune was not eroded when the beach height exceeded the wave run-up. The heaviest surges eroded away 12–14 m3 of the beach sand volume. The shore erosion was found to be related to the storm surge duration, the maximum SL, the run-up and the beach height prior to the surge.
The Capital Structure of Libertarian Production
Authors: Wiśniewski Jakub Bożydar
Published: July 2022

The purpose of the present article is to reflect on the intellectual origin of the close relationship between Austrian economics and libertarian philosophy. It suggests that the relationship in question is grounded in the fact that personal liberty and individual initiative, in addition to being significant moral values, are also crucial reservoirs of organizational efficiency and developmental drive. This implies that libertarian values can be disseminated, promoted, and implemented particularly effectively as a result of utilizing theoretical insights of the Austrian school, which is singularly committed to explaining the efficiency-enhancing features of the unhampered market process and entrepreneurial rivalry. In this connection, special attention is devoted to the liberty-promoting potential of Austrian contributions to the fields of capital, entrepreneurship, and the firm.
Some Prospects of Libertarian Punishment Theory: Rejoinder to Blasco and Marcos
Authors: Block Walter E.
Published: July 2022

Libertarian punishment theory was initially articulated by Murray N. Rothbard and Walter E. Block. It was broken down into four separate stages. To a great degree, this theory was accepted by Eduardo Blasco and Davie Marcos. However, they maintain it is in need of some slight adjustments and improvements, mainly dealing with the interest rate. The present paper claims their suggestion while valid, is unnecessary, since this theory already incorporates that element, at least implicitly.
Predicting the Consequences of Perceived Data Privacy Risks on Consumer Behaviour: An Entropy-TOPSIS Approach
Authors: Adebiyi Sulaimon Olanrewaju , Olayemi Gloria Amaka
Published: July 2022

Advancement in internet of things (IoT) and proliferation in the use of smart devices have raised concerns about the data privacy of online users. This study predicts the consequences of perceived data privacy risks on consumer behaviours in Lagos State, Nigeria using the integrated Entropy-Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). We employed Entropy to assign weights to each criterion. Subsequently, responses were systematically ranked to arrive at an inference using TOPSIS. 84.8% agree that any perceived cyber security threat or a breach in their data privacy would stop them from proceeding with the transaction or activity online, or the use of a digital product. Similarly, (86.7%), agree it is critical that online businesses only ask for customer information that is relevant to the use of the product or service. Thus, the findings indicate that the privacy paradox of enlightened online consumers tends to diminish when they are faced with perceived data privacy and cybersecurity risks.

Published: July 2022

Jaringan Tegangan Menengah (JTM) merupakan sistem tenaga listrik antar gardu induk dan gardu distribusi dengan lingkup dari terminal keluar (out-going) pemutus tenaga hingga peralatan pemisah/proteksi sisi masuk (in-coming) tranformator distribusi 20kV. JTM sebagai sistem distribusi yang menyalurkan listrik dan berhubungan dengan pelanggan harus memperhatikan tingkat keandalannya yaitu dapat menyuplai tenaga listrik ke konsumen secara continue. Tingkat keandalan sistem distribusi dapat ditentukan dengan menghitung SAIFI (System Average Interruption Frequency Index) yaitu indeks keandalan dari banyaknya frekuensi pemadaman. Berdasarkan hasil perhitungan dan analisis indeks keandalan berbasis sistem diperoleh hasil 10,89 kali/pelanggan/tahun dengan total energy not served (ENS) sebesar 57772 kWh, nilai ini menunjukkan keandalan sistem distribusi masih dibawah standar indeks SPLN 68-2:1986. Selanjutnya, diperlukan adanya analisis, evaluasi penyebab trip serta kebijakan anggaran  sebagai upaya untuk menekan nilai SAIFI. Kegiatan preventif meliputi : inspeksi rutin, pemasangan isolasi kawat, serta memanfaatkan teknologi IoT, database dan GPS untuk digitalisasi sistem untuk keandalan sistem distribusi.

The utilization of natural resources and energy is increasing day by day, one of which is the use of natural gas as fuel for both household and industrial needs. Safety aspects in the use of this gas must be considered because gas leaks can trigger fires. Therefore we need a tool that can detect and notify gas leaks as early as possible. This study proposes a gas leak detector based on the Internet of Things (IoT) using NodeMCU ESP8266 as a microcontroller. This detection system uses the MQ-2 sensor as a detector of gas levels and a flame sensor as a detector of ultraviolet light as an indication of a fire. The resulting output is a notification message from the Telegram Bot sent via NodeMCU. In this case, the buzzer and LED will give a signal if the MQ-2 sensor detects gas levels above 500 ADC, then the NodeMCU will send a command to the Telegram Bot to send a notification message in real-time. In addition, the detected gas levels are also displayed on the 16x2 LCD screen. The experimental results show that the ideal distance to detect gas is under 6 cm and fire below 20 cm with a sensor response time of 2 seconds. The existence of this tool is expected to minimize the risk of fire due to gas leakage.

Multilevel Inverter (MLI) merupakan salah satu jenis inverter yang memiliki gelombang tegangan keluaran bertingkat. Meskipun lebih baik dari inverter konvensional, MLI yang beroperasi pada frekuensi rendah masih mengandung harmonisa orde rendah pada tegangan dan arus keluaran yang berdampak negatif pada sistem kelistrikan. Untuk mengatasi masalah ini, banyak peneliti telah mengembangkan berbagai teknik kontrol dan pada modulasi inverter untuk mengurangi harmonisa dan meminimalkan kerugian penyaklaran dengan tujuan mengoptimalkan efisiensi inverter. Selective harmonic elimination pulse-width modulation (SHEPWM) adalah kontrol paling optimal dari semua metode yang telah dikembangkan untuk menghilangkan harmonisa orde rendah dari tegangan keluaran inverter. Namun, ada tantangan dalam proses analisis MLI menggunakan SHEPWM karena penyelesaian persamaan yang sulit. Bio-inspired intelligent algorithms (BIA) digunakan untuk memecahkan masalah ini. Paper ini menjelaskan secara lengkap review dari berbagai penelitian yang telah dilakukan sebelumnya terkait dengan prinsip operasi sembilan jenis BIA dan aplikasinya dalam mereduksi harmonisa. Kesimpulan dibuat berdasarkan informasi yang diambil dari literatur. Semua informasi penting dalam paper ini mengenai reduksi harmonisa pada MLI akan membantu penelitian di masa depan untuk merancang sistem konversi daya yang efisien.

ИДЕНТИФИКАЦИЈА РИЗИКА И ЊИХОВ УТИЦАЈ НА ДИНАМИКУ И ТРОШКОВЕ
Authors: Милекић Никола , Мученски Владимир
Published: July 2022

Један од основних елемената управљања пројектима јесте управљање ризиком пројекта, узимајући у обзир да ризици могу негативно да утичу на успешност реализације пројекта тако што неће бити остварен у задатом временском року, са одређеним квалитетом или у планираном буџету. Неизвесност било које врсте везана за реализацију постављених циљева може се назвати ризиком пројекта. Једини начин упознавања са карактерис­тикама пројекта лежи у системском приступу тј. анализи путем које је могуће сагледати како компоненте пројекта тако и њихове међусобне везе. Технике управљања пројектима нису ништа друго до покушај смањења неизвесности догађања у сврси достизања постављених циљева.

Analytical Method Development, Characterization, Evaluation of In-vitro Antioxidant and Anticancer Activity of Flavone Chrysin in HeLa Cells
Authors: ITTADWAR PARUL A. , Puranik Prashant K.
Published: July 2022

Chrysin is a very effective naturally occurring polyphenol belonging to the subclass of flavones showing abundant biological activities, including potential antioxidant and anticancer activity in numerous cancerous cells. In the present study, the properties of Chrysin were evaluated by performing the analytical method development using UV spectrophotometry and comparing its validation parameters in methanol (λmax-219 nm), distilled water (λmax-267 nm), 1.2pH buffer (λmax-269.6 nm) and 6.8pH buffer (λmax-268.2 nm). It was analyzed by high performance liquid chromatography (HPLC), high performance thin layer chromatography (HPTLC) and fourier transform infrared spectroscopy (FT-IR) studies. The characterization of Chrysin was performed using differential scanning calorimetry (DSC), scanning electron microscopy (SEM), X ray diffraction (XRD) studies and its log P value was evaluated. The in vitro antioxidant activity of Chrysin was evaluated using Ferrous ion chelation assay. The anticancer effect of Chrysin was studied on henrietta lacks immortal cell line (HeLa) by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) tetrazolium assay. The analytical method development and validation parameters confirmed the linearity, method reliability, accuracy, precision, and stability of Chrysin with RSD values < 2%. The HPLC analysis showed a sharp symmetric peak for Chrysin at a retention time of 3.036 min in the mobile phase, acetonitrile: methanol (65:35 v/v). The HPTLC analysis indicated the Rf value of 0.50 and 0.53 at 254 and 366 nm respectively for 5 μL sample in the mobile phase toluene: n-hexane: isopropyl alcohol (7:2:1 v/v). The FTIR and DSC studies confirmed the functionality and thermal behavior of Chrysin. The log P value of 3.236 indicated the high lipophilicity of Chrysin. SEM and XRD study suggested its crystalline behavior. The in-vitro Ferrous metal ion chelation was found in the range from 96.23 to 88.23% for concentrations ranging from 20–200 μg/mL. This indicated the increase in antioxidant activity of Chrysin with increase in its concentration. The MTT assay depicted the increasing concentration of Chrysin on HeLa cells and confirmed its anticancer effect by inhibiting the cell growth at IC50 value of 15 μM.

Technological development has led to the emergence of cooperation separately both geographically and in time zone in an organization in the form of a virtual organization. PT XYZ's Microsoft Solution and Service (DMSS) Department is one of the departments that provides digital services in the form of One-Stop-Solutions on Digital Services, both in on-premise and cloud infrastructure models with products and solutions based on Microsoft products for customers. In his service during the Covid-19 pandemic, this department implements virtual team coordination so that product development can continue as planned. However, on the other hand, the effectiveness of performance in implementing virtual organizations is still a challenge for the company. This is the focus of research to find out what factors influence the effectiveness of cooperation in the application of virtual organizations at PT XYZ in general and specifically in the Microsoft Solution and Service Department. This study conducted an analysis of seven factors by surveying 40 respondents at PT. XYZ. The results obtained are three factors consisting of depth of communication, technology, and training which have an influence on the effectiveness of the application of virtual organizations at PT. XYZ, while four other factors such as trust, shared understanding of knowledge, commitment, and leadership have no significant effect on the effectiveness of virtual organizations.

Authors: Munandar Musthafa Haris , Harahap Saimarlina , Irawan Feri
Published: July 2022

At this time the processing of coconut into coconut flour is widely carried out by factories, especially in areas that have a large population of coconuts. Hal ini disebabkan karena keuntungan yang didapat dari hasil pengolahan kelapa tersebut bisa mendapatkan keuntungan yang besar. This is because the profits obtained from the results of processing coconut can get large profits. The problem that has occurred so far is that there are many people who want to process coconuts, but are not accompanied by sufficient knowledge and knowledge of the quality of coconuts that the factory wants, so it is undeniable that there are also many coconuts that have been processed into coconut flour but are not sold in the market. The analysis method used in this study used an image processing method based on digital images with a GUI (Graphical User Interface) interface media that utilizes matlab software. Image processing consists of several processes, the first of which is the operation of changing the color to grayscale. The second process is a grayscale to binary color change operation using the threshold method. The third process is the morphological process of filling holes to remove noise from the threshold image results. The results of the study using the Image Management method are expected to provide knowledge and knowledge to the public about the quality of coconuts expected by the factory, especially to identify the differences between rotten coconuts and rotten coconuts.
O Ambulatório Médico de Especialidades de Psiquiatria no início da pandemia de COVID-19
Authors: Santos Ariella Hasegawa Galvão , Amino Denise , Laranjeira Ronaldo Ramos
Published: July 2022

Introdução: Nenhum país estava adequadamente preparado para a pandemia de COVID-19. Segundo a Organização Mundial de Saúde (OMS), 93% dos países em todo o mundo tiveram algum tipo de interrupção nos serviços de saúde mental. O AME Psiquiatria utilizou a informações de autoridades de saúde internacionais e nacionais para a tomada de decisões na adaptação de normas e rotinas na unidade. Objetivo: O objetivo deste estudo é descrever as adaptações realizadas por um serviço público especializado em saúde mental no início da pandemia para manter a assistência segura frente aos riscos de contaminação pela COVID-19 com base nas informações disponíveis. Assim como fornecer os dados do perfil dos pacientes atendidos pré e pós início da pandemia. Método: Estudo transversal. Adaptações descritas com base em relatórios de gestão, manuais de procedimentos, atas de reunião e apresentações de treinamentos. Amostra de 10.120 pacientes selecionados por conveniência que frequentaram pelo menos um atendimento individual com psiquiatra entre maio de 2019 a dezembro de 2020. Este período foi escolhido obter um comparativo de dois grupos pré (maio 2019 a fevereiro de 2020) e pós pandemia (março a dezembro de 2020) com o mesmo tempo de 10 meses. Resultados: As adaptações realizadas possibilitaram a manutenção dos atendimentos no AME Psiquiatria e a comparação do perfil dos pacientes que iniciaram tratamento antes da pandemia versus após início da pandemia. Não houve mudança em relação ao sexo nos dois períodos analisados, sendo que 65% das pessoas eram mulheres e 35% homens. Houve redução em 26% de crianças e adolescentes (faixa etária de 0 a 19 anos) e de 14% de idosos (60 anos ou mais), com aumento de 7% de adultos na faixa etária de 20 a 59 anos. Conclusão: Apesar dos estudos apontarem fatores diretos e indiretos da COVID-19 como predisponentes para o desenvolvimento de transtornos mentais, não podemos afirmar que esta mudança de perfil diagnóstico dos pacientes do AME Psiquiatria pós início da pandemia tenha relação com a COVID-19. Por outro lado, a publicação de achados de um ambulatório público especializado em saúde mental, que manteve os atendimentos no início e durante a pandemia, são de grande valia para apoiar outros pesquisadores nesta área.
