This study investigated the growth, mortality, recruitment, and catch estimates of Nile perch, Lates niloticus (Linnaeus, 1758), in Upper Victoria Nile, basing on total catches and length-frequency data collected between 2008 and 2018. The asymptotic length (L∞) had a value of 93.45 cm TL, growth curvature (K) was 0.446 year-1, total mortality (Z) was 1.85year-1, natural mortality (M) was 0.79 year-1, fishing mortality (F) was 1.09 year-1, exploitation rate (E) was 0.59 and growth performance index(ᴓ) of (L∞) was 3.604. There were two peaks recruitment period, a minor one in March and a major one in August. These respectively accounted for 12.8 and 26.3 percent of the total catch. The optimum sustainable yield (E0.5), maximum sustainable yield (Emax) and, economic yield (E0.1) was 0.278, 0.421 and 0.355 respectively. The findings suggest that there is a decline in the population of Lates niloticus in Upper Victoria Nile. Therefore, strict management of the fishery by adhering to the recommended slot size of 50-85 cm TL and curtailing use of illegal gears is needed. This will be possible through enforcement of regulations, monitoring, control and surveillance in order to ensure sustainability of the Nile perch fishery and ecosystem restoration in the Upper VictoriaNile.Keywords: Lates niloticus; Catch rates; Growth parameters, Upper Victoria Nile.

Authors: Maliki Muniratu , Hilary Ifijen Ikhazuagbe , Emmanuel Khan Mulu
Published: March 2021

Anaerobic digestion of rubber processing effluent (RPE) was conducted at 1:1 Effluent to Inoculums ratio to obtain biogas at a 40–day retention time. The physicochemical properties of the RPE were determined before and after anaerobic digestion. Digestate obtained thereof was used as soil amendment to investigate its bio-fertility potential. To study the effects, three kilograms (3Kg) of soil samples were separately treated with 0, 200, 400, 600 of the digested RPE. The effluent applied were thoroughly mixed with the soil, watered regularly and left for eight weeks for adequate mineralisation and equilibration. The soil physicochemical properties were determined before and after the amendment. The results from the amended soils showed that application of the digestate enhanced soil quality (as soil organic carbon, N, P, K, Ca, Na and % base saturation were significantly higher than in the control). However, the soil pH remained in the acidic region and the soil exchangeable acidity reduced.

Data transformation in biological assays
Authors: Péllico Netto Sylvio , Behling Alexandre
Published: March 2021

The analysis of variance is the statistical test most used for comparison of three or more means simultaneously. Its application requires, however, the compliance to some assumptions, with main emphasis on normality of the data and homoscedasticity of variances. When such requirements are not met, one of the alternatives is the data transformation to enable the continuity of the experimental evaluation. With the proposition of the Tukey’s data transformation system, understood as a power transformation system, i.e. the application of nth root on a data set (X⅟n) this statistical procedure has methodologically evolved to ensure such solutions. In the present research we proposed a complement to this system, denominated here as transformation in four steps, with inclusion of two hypothesis tests to evaluate normality and homoscedasticity. This was applied on experimental data to evaluate the amount of radiation available at soil level within stands of Acacia mearnsii De Wild. We have proposed a model for data transformation to simultaneously obtain homoscedasticity and normality. The methodology was appropriate to ensure these two statistical aspects on the experimental data, allowing comparison of eight treatments by conventional analysis of variance. Index terms: Analysis of variance, homoscedasticity, normality.
Covid-19. Civic Universities, Societal Innovation and the Recovery of Local Communities
Authors: Goddard John
Published: March 2021

Corona virus has had a differential impact on not only various age and ethnic groups but also on different localities. In many of these places, universities have hitherto acted in dual roles as key anchor and as knowledge institutions. During the crisis, many universities have worked with heath service providers, businesses, local authorities and the community and voluntary sector with real pace, skill and scale in a way that has reinforced the trust and confidence of local people in their universities. Whilst the immediate focus has been on the contribution of the medical and life sciences, civically minded universities have also drawn on the social sciences to help public authorities address the challenges of economic and  social recovery in a more sustainable and inclusive way. This has required them to put citizens at the heart of placed based societal innovation. Going forward universities and their funders must learn from the good they have done during the health crises and then seek to build a ‘new normal’ based on values rather than on quasi-artificial performance metrics.  A values approach would embed a university more strongly within local government structures where it could then benefit from political influence and financial systems. Firms of all sizes and from all places, local and national would then be much more aware of the contribution universities can make to society in the round.

Published: March 2021

This paper investigated a combined process of a modified attached-growth anoxic-oxic-anoxic reactor (AG-AOAR) as a sustainable and effective post-treatment system for septic tank effluent was developed. The AG-AOAR was operated by varying hydraulic retention times (HRTs) from 24 to 72 h. The results showed that the AG-AOAR achieved highest removal efficiencies of 84, 66 and 91% of chemical oxygen demand (COD), total nitrogen (TN) and ammonium nitrogen (NH4-N), respectively, under the HRT of 72 h, resulting its effluent meeting the international and national discharge quality standards for non-sewered sanitation system. The Stover-Kincannon model was applicable to describe the kinetic constants of COD, TN, and NH4-N removal in the AG-AOAR (R2 > 0.85). Accordingly, the maximum utilization rates (μmax) were determined to be 41.1, 0.15 and 0.50 g/(L-d) for COD, TN and NH4-N removals, respectively, while the saturation constants (KB) were 57.7, 0.12 and 0.51 g/(L-d), respectively. These constant values could be applied for the design of the AG-AOAR to produce treated effluent meeting desired standards.

Published: March 2021

Fruits play important role in providing the individuals daily dietary needs from vitamins, iron, and some metals that are needed in the body as dietary supplement or as an important element that form some hormones or enzymes in small concentrations, if exists in high concentrations become toxic with side effects. The presence of heavy metals such as of Fe, Cd, Pb, Cr, Mn, Ni, Co, and Zn in Ximenia americana and sclerocarya birrea wild fruits were determined using standard methods such as AAS. Results obtained from this study revealed that the concentration of the metals in sclerocarya birrea was Iron, (8.83 ± 0.10) Cadmium (0.01 ± 0.00) Lead (0.04 ± 0.02) Chromium (0.19±0.10) Manganese (4.27 ± 0.20) Nickel (0.21 ±0.10) Cobalt (0.09 ±0.01) and Zinc (2.96 ± 0.02) mg/g. On the other hand, Ximenia americana content was Iron, (6.37 ± 0.10) Cadmium (0.02 ± 0.01) Lead (0.01 ± 0.00) Chromium (0.24±0.01) Manganese (2.50 ± 0.10) Nickel (0.29 ±0.10) Cobalt (0.17 ±0.00) and Zinc (2.31 ± 0.06) mg/g respectively. Highest concentration of Iron was recorded as (8.83 ± 0.10) mg/g in the sclerocarya birrea sample analyzed, while Lead and Cadmium were found to be the least with concentration of (0.01 ±0.00) mg/g in both samples. Their concentrations are within the maximum allowable concentration (MAC) set by FAO/WHO. The findings of this study reveal that there are no health risks associated with the consumption of heavy metals through the intake of these two fruits.
Enhancing Design Features of Asymmetric Spur Gears Operating on a Specified Center Distance Using Tooth Sum Altered Gear Geometry
Authors: Dsa Avil Allwyn , Gonsalvis Joseph
Published: March 2021

Asymmetric gears have evolved from the rising demand for power transmission drives with high load-carrying capacity, surface durability, and service life. Direct design and S± profile shifted system are the most common approaches used for enhancing design features by geometry modification in asymmetric gears. This paper aims at establishing asymmetric gear geometry modification using tooth sum alteration for a family of gears running on a specified center distance as a feasible design approach. A complete mathematical treatment of the design approach is provided, and an in-house developed computer program is used for numerical simulation. The paper explores the influence of dynamic load factors, location factors for bending, specific sliding on load-bearing capacity, and surface durability on different tooth sum alterations. The study concludes that tooth sum altered asymmetric gear geometry can be employed as an effective design technique that offers designers flexibility in designing gears for surface wear, load-bearing, and tooth life.
FROM THE HISTORY OF OSSETIC WRITING. G.V. BAEV’S MEMORANDUM OF 1925
Authors: ТОМЕЛЛЕРИ В.С.
Published: March 2021

Настоящая статья содержит ранее не публиковавшийся и неизвестный меморандум Г.В. Баева, который теперь хранится в его личном архиве (Берлин, Национальная библиотека). В этом коротком тексте (всего восемь страниц), написанном на русском языке в 1925 году и адресованном Исполнительному комитету Северо-Осетинской Автономной Области, автор выражает свое негативное мнение о введении латинского алфавита в Осетии, излагая культурные и практические причины предпочтения им кириллицы, которая впервые использовалась, в гражданском варианте, в осетинской грамматике, составленной академиком А.М. Шегреном в 1844 году. Издание меморандума основывается на двух практически идентичных машинописных черновиках и преследует две главные цели: сделать этот текст доступным для более широкой академической публики и, следовательно, стимулировать поиск оригинального текста в архивах Республики Северная Осетия-Алания.

The present article features a hitherto unpublished and unknown memorandum by G.V. Baev, now kept in his personal archive (Berlin, National Library). In this short text (eight pages), written in Russian in 1925 and addressed to the executive committee of the North Ossetian autonomous region, G.V. Baev expresses his negative opinion about the introduction of a Latin-based alphabet in Ossetia and exposes the cultural and practical reasons of his preference of the Cyrillic script, firstly used, in the civil typeface, in the Ossetic grammar composed by the academician A.M. Sjögren in 1844. The edition of the memorandum is based on two almost identical machine-type drafts and has two major aims: to make this text available to a broader academic audience and, as a consequence, to stimulate the search of the original text in the archives of the Republic of North Ossetia-Alania.
Three Dimensional Terrain Modeling for Tectonic Geomorphology of Chinara Anticline, Northern Iraq
Authors: Thannoun Rayan
Published: March 2021

Analysis of the terrain using three-dimensional models offers a deep insight view of ground surface topography and terrain representation. The Chinara anticline is one of the main structures of NW-SE trends for the highly folded zone in northeastern Iraq. The objective of this study is to understand the interrelationship between topography and morphotectonic features using three-dimensional models. This research employed fourth generates principal raster derivative products from the DEM using ArcGIS. To understand the undulating of this anticline with the morphotectonic style, the adaptive equation has been suggested to determine the direction and amount of the main tectonic forces, which can be applied to other undulated anticlines. The values of northeastern and southwestern limbs undulating index UI are 11.7 and 7.8 respectively that indicates the strong tectonic force towards the northeast. Two listric faults have been conducted via the field survey that confirmed by remotely sensed interpretation and DEM products. These listric faults had an intensive impact in comparison with concluded strike-slip faults, and then the Chinara anticline would be less structural undulating in a region of vicinity syncline to Perat undulation. The morphotectonic landscapes reveal that the listric fault has branched into two parts, the first one extending to form the anticline and the other comprises the structural dilemma.
Distribution of Steranes and Triterpanes Biomarkersas Indication of Depositional Environment and Maturity of Sargelu and Kurrachine Formations in Different Wells Northern Iraq
Authors: Al-Dolaimy Arwa
Published: March 2021

Eight cuttings samples were obtained from Sargelu and Kurrachine formations in different wells at different depths to detect steranes and triterpanes biomarkers as an indicator of the depositional environments and thermal maturity of organic matter. This was accomplished using GC-MS technology. The diasterane/sterane ratio showed low ratios in analyzed samples (BJS2, JKS3, BJK1, JKK4, JKK7) as in most marine carbonate sources, while algal-bacterial organic matter contribution for the samples analyzed based on the predominance of C23 tricyclic relative to the C19 tricyclic terpene and the C23 tricyclic greater than C24 tricyclic terpane. The Gammacerane index indicated that normal salinity conditions during depositions. The biomarkers related to maturation such as diasterane/sterane, Ts/(Ts+Tm), and C29Ts/C29 hopane show that the organic matter in Ain Zalah well (Sargelu Formation) is within early mature (oil window).
«На острове Патмос»: отшельник С.И. Калмыков
Authors: Chudinovskaya T.G.
Published: March 2021

The article is devoted to the work of Sergei Kalmykov, a Russian artist, illustrator, decorator, and writer. His art career started in the 1910s in Saint-Petersburg and later he called himself as “the last avant-garde of the first draft”, being aside of the mainstream of the development of Russian art. His free art was like a diary, like an endless dialog with himself. Each of his paintings from this monologue is a fragment tear out from one whole. The author interprets the painting “On the Island of Patmos” on the basis of an interdisciplinary approach that combines the principles of art history, cultural studies and mythopoetic analysis of a work of art. The study shows how complex his 'web' of creating thinking is and how it unexpected and deeply intertwined in one cultural field with other artists (Velimir Khlebnikov, Robert Lax) and even with religious images of almost two thousand years ago (John the Theologian).

Статья посвящена творчеству Сергея Ивановича Калмыкова, русского художника, иллюстратора, декоратора, писателя. Начав свой творческий путь в 1910-е годы в петербургской художественной среде, он впоследствии сам себя называл «последним авангардистом первого призыва», оказавшись на задворках главенствующей линии развития отечественного искусства. Его свободное творчество представляло собой форму дневника, бесконечного одинокого разговора с самим собой. Каждая его картина из этого монолога — вырванный фрагмент из одного целого. На основе междисциплинарного подхода, сочетающего искусствоведческий, культурологический и мифопоэтический принципы анализа художественного произведения, автор статьи интерпретирует картину «На острове Патмос». Исследование демонстрирует, как сложна «паутина» творческого мышления, нити которого ткутся посредством художественного сознания и переплетаются самым неожиданным образом в общем культурном поле с другими творческими судьбами (Велимир Хлебников, Роберт Лакс) и даже с религиозными образами почти двухтысячелетней давности (Иоанн Богослов).

The famous collections of new art works of the late 19th – early 20th centuries of the great collectors S.I. Shchukin and I.A. Morozov have a pronounced individual character. The documentary materials of these collectors, stored in the Department of manuscripts of the Pushkin State Museum of Fine Arts, are also distinct. The preservation, number and typology of documents reflect not only the personality and fate of the collectors, but also the history of the country. The first special address to the history of formation and the composition of I.A. Morozov's documents collection complements the collector's way and the fate of his collection. Leaving practically no personal and family documents, I.A. Morozov carefully handed over business papers to the museum curators, confirming the immaculate provenance of his collection. Drawing attention to personal provenance funds brings to the fore the importance of their acquisition and preservation.

Знаменитые собрания произведений нового искусства конца XIX – начала XX века великих коллекционеров С.И. Щукина и И.А. Морозова носят ярко выраженный индивидуальный характер. Также непохожи и документальные материалы этих собирателей, хранящиеся в отделе рукописей Государственного музея изобразительных искусств им. А.С. Пушкина. Сохранность, численность и типология документов отражают не только личность и судьбу коллекционеров, но и историю страны. Первое специальное обращение к истории формирования и составу коллекции документов И.А. Морозова дополняет коллекционерский путь собирателя и судьбу его коллекции. Не оставив практически никаких личных и семейных документов, И.А. Морозов бережно передал музейным хранителям деловые бумаги, подтверждающие безупречный провенанс его коллекции. Привлечение внимания к фондам личного происхождения актуализирует важность их комплектования и сохранения.
Коллекция живописи великого князя Алексея Александровича в Алексеевском дворце
Authors: Basova I.G.
Published: March 2021

In the St. Petersburg Alekseevsky Palace, which belonged to the Grand Prince Alexey Alexandrovich (1850–1908), a rich collection of paintings and drawings was gathered. This collection has never come under the scrutiny of researchers. Shortly after the owner's death, it was sold at auction. Thanks to the inventory found in the Russian State Historical Archive, it was possible to reconstruct its contents, which made it possible to judge the artistic preferences of its owner. The collection was based on works by Russian artists of the second half of the 19th century, with many of whom the Grand Prince was personally acquainted. In the article, the pictures are grouped and considered on a thematic basis. The largest section of the collection was made up of works by marine artists. Special attention is paid to the most outstanding and unique exhibits of the collection. The Tretyakov Gallery contains one painting from the collection of the Alekseevsky Palace (A. Gebens. Family. 1856). Its provenance was established thanks to a unique owner's sticker, preserved on the back of the canvas. The study of inventories helped to restore the original name of the work.

В петербургском Алексеевском дворце, принадлежавшем великому князю Алексею Александровичу (1850–1908), была собрана богатая коллекция живописи и графики. Эта коллекция никогда не попадала под пристальное внимание исследователей. Вскоре после смерти владельца она была распродана с молотка. Благодаря обнаруженной в Российском государственном историческом архиве описи удалось реконструировать ее состав, что позволило судить о художественных предпочтениях ее владельца. Основу коллекции составляли произведения русских художников второй половины XIX века, со многими из которых великий князь был лично знаком. В статье картины сгруппированы и рассматриваются по тематическому признаку. Самый большой раздел собрания составили работы художников-маринистов. Особое внимание уделено наиболее выдающимся и уникальным экспонатам коллекции. В Третьяковской галерее хранится одна картина из собрания Алексеевского дворца (А. Гебенс. «Семейство», 1856). Ее провенанс удалось установить благодаря уникальной владельческой наклейке, сохранившейся на обороте холста. Изучение описей помогло вернуть произведению подлинное название.

The article is devoted to the history of a unique collection made by famous American patron and curator Peggy Guggenheim. For several decades, she has been gathering works by European Cubists, Abstractionists and Surrealists, creating the huge collection of the 20th century art. But she made the most significant contribution to the development and popularization of modernism by organizing the «Art of this Century» gallery in New York. This gallery hosted for the first time exhibitions of artists who later became known as abstract expressionists. Their work loudly declared itself on the international art scene and won worldwide recognition.

Оба они — художник и У. Гамильтон, меценат и коллекционер, увлеченно занимавшийся вулканологией, были яркими фигурами истории и культуры века Просвещения. Их сотрудничество является подтверждением научных и художественных достижений культуры Италии в век «просвещенного абсолютизма», когда в Королевстве обеих Сицилий правила династия испанских Бурбонов.
TEST PARTICLE SIMULATIONS FOR NON-MAXWELLIAN PLASMA TRANSPORT: DISCRETIZED COLLISIONAL OPERATOR
Authors: Vozniuk D.V. , Shyshkin O.A. , Girka I.O.
Published: March 2021

The plasma observed in modern fusion devices is very often characterized by strongly non Maxwellian distribution function. That is the direct result of inevitable application of plasma heating techniques, such as neutral beam injection (NBI) and ion/electron cyclotron resonance frequency (ICRF/ECRF) heating, which induce the non Maxwellian fast ions. Another cause of transfer from Maxwellian to non Maxwellian is the reconnection of magnetic field lines followed by formation of magnetic resonant structures like magnetic islands and stochastic layers. One of the basic approaches used to simulate fusion plasma is test particle approach based on a solution of the equations of test particle motion. To make this approach more comprehensive one should take care of plasma particle interactions, i.e. Coulomb collisions in non Maxwellian environment. In present paper the expressions for the discretized collision operator of a general Monte Carlo equivalent form in terms of expectation values and standard deviation for an arbitrary non Maxwellian bulk distribution function are derived. The modification of transport coefficients of impurity ions caused by the transition from the background Maxwellian to non Maxwellian plasma is studied by means of this discretized collision operator. On this purpose, the set of monoenergetic neon test impurities is followed in a toroidal plasma consisting of bulk deuterons and electrons. The non Maxwellian distribution of the bulk is obtained by adding a fraction of energetic particles of the same species. It is demonstrated that a change of collision frequencies of impurities takes place in presence of this energetic fraction leading to a change of impurity neoclassical transport regime.
INVESTIGATION OF OZONE SYNTHESIS IN THE NEGATIVE PULSED CORONA DISCHARGE IN OXYGEN AT THE COMBINED SUPPLY VOLTAGE
Authors: Golota V.I. , Kadolin B.B. , Paschenko I.A.
Published: March 2021

The influence of combined supply voltage parameters (bias voltage and voltage pulse amplitude) on efficiency of ozone synthesis in the negative pulsed corona discharge in oxygen was obtained. Pulse overvoltage led to intensification of discharge processes. Bias voltage applied during the discharge channel relaxation essentially increased the efficiency of ozone synthesis. It was established that the “optimal” bias voltage which provides maximum ozone generation doesn’t depend on voltage pulse amplitude, but depends on input oxygen concentration and generated ozone concentration.

Patients’ Experiences of an Acceptance and Commitment Therapy-Based Approach for Psychosocial Difficulties Relating to an Appearance-Affecting Condition
Authors: Zucchelli Fabio A , Donnelly Olivia , Sharratt Nick D , Hooper Nic , Williamson Heidi M
Published: March 2021

Some individuals with appearance-affecting conditions experience psychosocial challenges such as social anxiety and avoidance. Acceptance and Commitment Therapy (ACT) may offer a suitable approach for these challenges. This qualitative study investigated the lived experiences of patients with such appearance related concerns, who had been through a one to-one ACT-based intervention. It was expected that this would offer insights into the processes underpinning any positive impacts of therapy, potentially including ACT-specific elements. Semi structured interviews were conducted with six female patients of a specialist clinical psychology service, where an appearance focused ACT-based intervention was delivered. Participants described their experiences of therapy, any impact it had on their lives, and to what they attributed any changes. Interpretative Phenomenological Analysis, a qualitative method suited to exploring individuals’ lived experiences, was

used. Four superordinate themes included: Progress in body confidence, developing ways to take control over (re)action, developing acceptance of appearance, and compassion. These processes emanated from the participants’ relationship with the treating psychologist, as well as specific skills used in sessions, and were enacted through participants’ engagement in life-fulfilling activities. One-to-one ACT-based therapy appeared to help expedite the process of accepting a changed appearance, which participants highlighted as an important

step in adjusting to their appearance. Participants’ account of their improved body confidence can be understood

in terms of an existing model of body image coping, offering a theoretical framework worthy of exploration in relation to ACT processes for this population. Participants’ accounts also convey the centrality of therapists expressing compassion and helping patients to cultivate self-compassion.
A busca pela eternidade: aproximações entre Murilo mendes e Dante Alighieri.
Authors: Santos João Victor
Published: March 2021

With the intention of studying the relationship between Being and Eternity, the present study sought to bring together As metamorfoses, by Murilo Mendes, and The divine comedy, by Dante Alighieri. With the support of texts such as those by Carvalhal (1986) and Nitrini (2015), we used Comparative Literature as a theoretical framework in order to compare the lyric verses of one and the epics verses of the other, in order to analyze how it was the process of receiving the Italian work by the Brazilian. Based on Lucchesi (2013), for whom the dantesque comedy is seen in a diluted way in 20th century Brazilian poets, we undertook the appreciation of murilian verses and raised hypotheses about how they would associate with Italians through thematic and sonorous relationships imagery. With that, we were able to conclude that As metamorfoses absorbs traces of The divine comedy and is different from it, managing to maintain the balance between influence and originality.
Clinical Adjunct Nursing Faculty Virtual Mentoring Experience:A Qualitative Study
Authors:   Hillsborough College, FL, Reyes Jennifer
Published: March 2021

Nursing and nursing education have been surrounded by discussions of shortages for many years. The United States lacks qualified nurses to care for its aging and increasing acutely ill population. The lack of qualified nurses stems back to several issues, at the forefront, a lack of qualified nurse educators. Due to the demand for skilled and competent nursing faculty, schools of nursing have been utilizing bedside nurses to teach in the clinical setting. While many are experienced bedside nurses, they may not be formally prepared to teach students. Clinical adjunct nursing faculty are also unique because they may never step foot on a college or school of nursing campus, teaching exclusively at the clinical site. This can lead to feelings of stress and lack of support from the other faculty members. It may also make it difficult to help prepare and guide clinical adjunct faculty as they teach and encounter educational issues without proper training. Mentoring is routinely cited as valuable to new faculty transitioning to the education role. The purpose of this study was to explore a new trend in mentoring, virtual mentoring, and determine if it is of value to clinical adjunct nursing faculty. Guided by a basic qualitative research design, eleven clinical adjunct faculty who have experienced virtual mentoring were interviewed in order to gather their perspective of the process and formulate interventions that may enhance the virtual mentoring process for this faculty population.

Rencana pemindahan Ibu Kota Negara (IKN) di Provinsi Kalimantan Timur memiliki tantangan besar pada aspek lingkungan terutama bagaimana memastikan pembangunan kota dapat tetap mempertahankan fungsi hutan, keanekaragaman hayati dan tidak merusak lingkungan. Konsep Forest City muncul dalam upaya mitigasi peluang kerusakan lingkungan khususnya hutan dalam perencanaan dan pembangunan IKN. Pada kajian ini diidentifikasi konsep Forest City untuk pembangunan IKN beserta prinsip, kriteria, dan indikator dengan menganalisis kondisi eksisting IKN, arah pembangunan Provinsi Kalimantan Timur dimana didalamnya terdapat calon wilayah IKN, isu dan potensi dampak lingkungan akibat pembangunan, serta dengan memperhatikan perkembangan konsep pembangunan kota di dunia (benchmarking). Berdasarkan kajian ini, konsep Forest City yang sesuai dengan kondisi calon wilayah IKN adalah kota hutan yang didominasi oleh bentang lanskap berstruktur hutan atau RTH yang memiliki fungsi jasa ekosistem seperti hutan dan dengan pendekatan lanskap yang terintegrasi untuk menciptakan kehidupan yang berdampingan dengan alam. Konsep Forest City tersebut dijabarkan menjadi enam prinsip yaitu:1) konservasi sumber daya alam dan habitat satwa; 2) terkoneksi dengan alam; 3) pembangunan rendah karbon; 4) sumber daya air yang memadai; 5) pembangunan terkendali (Anti-Sprawl Development); 6) pelibatan masyarakat dalam mewujudkan Forest City. Setiap prinsip tersebut dijabarkan kembali berdasarkan kriteria dan indikator untuk memastikan setiap prinsip dapat terpenuhi di dalam perencanaan pembangunan IKN.

Homebound individuals face substantial barriers to receiving COVID-19 vaccines as they cannot or rarely leave their homes because of medical, psychiatric, cognitive, functional, transportation-related and social reasons. There are at least 75,000 Ontarians aged 65 years and above who are homebound, with the majority being women and people aged 85 years and above. Much of this older homebound population requires mobile in-home COVID-19 vaccination, which could be prioritized by residence in high SARS-CoV-2 risk neighbourhoods.

Anesthesia for Cesarean Section in Hypothyroid Patient

Abstract

Thyroid disfunction is common in woman of child-bearing age population. Multiple organ are influenced with thyroid dysfunction and may contribute to complication during surgery and pregnancy. A 37-years-old female with hypothyroid was scheduled for cesarean section. Thyroid stimulating hormone (TSH) and thyroxine (T4) level was 14,87 µUI/mL and 71 nmol/L. The patient had levothyroxine therapy for 6 weeks. On physical examination, the general condition was good. She underwent spinal anesthesia with bupivacaine 0,5% 7,5 mg and fentanyl 25 µg. The baby was born with Apgar score 8/9 and the surgery was done without any complication. The patient was discharged from the hospital on the 3rd day after surgery. The hypothyroid patient may experience complication of myxedema comatous, respiratory disorder and hypotension during surgery. The elective surgery was best postponed until a euthyroid state was achieved. Low dose spinal anesthesia, adequate monitoring, hypothermia prevention, reducing opioid dose and continuing levothyroxine therapy was needed to prevent the complication if the euthyroid state was able not able to achieve. As conclusion : spinal anesthesia may be done for cesarean section in hypothyroid patient.
Gender Representations in Social Media and Formations of Masculinity
Authors: Parkins Maya , Parkins John
Published: March 2021

Social media has become a primary socializer as it has the ability to shape the identity and perspectives of its users. Gender socialization is the process in which people learn and internalize norms and behaviours associated with their respective gender.  Through their own social media platforms, influencers post representations of self that they feel represent themselves in the world. Since these influencers are popular, many adolescents are able to see and process these photos/videos as a part of their own process of identity formation. This study asks the question, how do male influencers demonstrate masculinity through their posts and comments? The literature reviewed for this study offers insight on the formation and representation of masculinity. Key concepts include hegemonic masculinity and defensive heterosexuality which aid in understanding masculinity as it is manifested in our society. The study sample includes ten male instagram influencers. Five photos were taken from their account that demonstrated representation of self and were each judged based on a set of criteria consisting of six factors. The results of this study show that these influencers are in fact demonstrating specific modes of masculinity through their photos which is consistent with how masculinity is portrayed in society today. However, these photos also demonstrate that some male influencers are shifting away from patriarchal forms of masculinity and are showing more interest in grooming and fashion, therefore highlighting a metrosexual mode of masculinity.
