Pengaruh Penggunaan Prepacked Aggregate Concrete Terhadap Perbaikan Join Balok Kolom Eksterior Pracetak Pasca Pembebanan Siklik Statik
Authors: Nurjannah Siti Aisyah
Published: April 2021

Saat mengalami beban gempa, struktur rangka bangunan akan menyerap energi gempa secara terus menerus sehingga memasuki keadaan plastis dan mencapai batas kekuatannya, sehingga diharapkan terjadi sendi plastis pada komponen join, yaitu pada ujung balok di muka kolom. Tingkat kerusakan yang terjadi pada struktur bangunan yang menahan beban gempa adalah rusak ringan, rusak sedang, atau rusak berat. Struktur dengan jenis kerusakan ringan dan sedang masih bisa diperbaiki dan diperkuat. Sedangkan, struktur dengan kerusakan tingkat berat tidak dapat diperbaiki. Penelitian ini membahas kinerja join balok kolom eksterior pracetak yang mendapat beban siklik statik dalam dua tahap. Setelah mengalami kerusakan akibat pembebanan tahap ke-1, join diperbaiki. Setelah beton prepack cukup umur, join diuji dengan beban siklik statik tahap ke-2. Hasil uji beban yang dikaji adalah perbandingan kinerja join pada tahap ke-1 dan ke-2 yang meliputi: daktilitas, disipasi energi, momen-kelengkungan, dan pola retak.

Authors: Kuswara Kuswara
Published: April 2021

Fenomena perkembangan kawasan perbatasan dengan negara tetangga menunjukkan semakin strategisnya kawasan perbatasan disatu sisi sementara di sisi lain kawasan ini secara umum masih sangat terbelakang dibandingkan kawasan lain di Indonesia. Untuk itu diperlukan upaya percepatan pengembangan kawasan perbatasan. Berkaitan dengan pengembangan kawasan perbatasan, salah satu aspek yang perlu diperhatikan adalah keberadaan permukiman yang ada di kawasan ini. Upaya pengembangan permukiman ini dilakukan dalam rangka mengubah paradigma pembangunan di kawasan perbatasan dari paradigma ”halaman belakang” menjadi ”halaman depan” dan dilakukan dengan pendekatan yang seimbang dan terpadu antara pendekatan keamanan (security approach) dan pendekatan kesejahteraan (prosperity approach). Dalam pengembangan paradigma pembangunan tersebut, peran permukiman memegang peranan yang sangat penting karena menjadi salah satu aktivitas terdepan yang ada di kawasan perbatasan. Untuk mendukung hal itu, maka diperlukan upaya untuk menemukenali tantangan pengembangan permukiman sebagai dasar untuk menentukan arah pengembangannya yang sesuai sehingga permukiman di kawasan perbatasan dapat menjadi beranda terdepan atau welcome window wilayah NKRI.

Comparison Between the BOQ of Conventional and BIM Method on BPJS Building in Central Jakarta
Authors: Akbar Mutia Hanuun Ufaira
Published: April 2021

In the construction planning process, the calculation of the quantity of each project work was packaged in a Bill of Quantity (BoQ) to complete the project and greatly affected the continuity of the entire construction construction process. With advances in technology in the world of construction, it could simplify planning in built a building and could increased the accuracy of calculations without using assumptions that could increased the volume of work. One of the results of current technological advances was the creation of the Building Information Modeling (BIM) method, a method that was able to simulate all information in a development project into a 3-dimensional model. Currently the use of the BIM method in Indonesia was still limited so that in this research, the aim was to determine the effectiveness of the use of BIM on the accuracy calculation of the volume of the BoQ and to know the percentage comparison. The building project that was used as a comparison was a building with the middle rise building category, namely the Central Jakarta BPJS Building. Based on the research conducted, it was found that the difference between conventional and BIM results on pilecap components was 5%, column 6%, beam 35%, floor slabs 2%, stairs 22%, ceiling 2.26% floor coverings 14% lower than conventional calculations but for the wall component the BIM calculation is 0.78% greater than the conventional calculation. So that the total percentage ratio is 10%, thus this proves that the use of the BIM method in calculating quantity was effective in terms of calculation accuracy.
A Study of Baumeister’s Self Defining Process in The Blind Assassin
Authors: Batool Fatima , Nissa Meher - ul - , Khan Asia
Published: April 2021

This paper explores the novel The Blind Assassin through the lens of Baumeister’s self-defining process. Identity, being an interpretation of self, lies in persistence and consistence over time. Identity crisis is the inability to define basic values, long-term goals and major affiliations, all of which help a person in the process of self-defining. The Blind Assassin being the story of two sisters, Iris Griffen and Laura Griffen, is helpful in developing a comparison of the two characters who are subjected to same upbringing and same social surroundings. The elder sister manages to assert her will in a competitive society while the younger one suffers from identity crisis and finds solace in suicide. Baumeister’s model of identity provides basis to interpret the inability of Laura in defining herself. The more a person is socially compatible the more she is at ease with herself. Her biological, social and sexual needs never addressed, however, she keeps trying to make choices and struggles to realize her potential. She ends up discontented as she is taken as an eccentric and dissatisfied as her own sister gives her the greatest shock of her life. The more a person is allowed to make choices the more successful she is in defining herself. Laura completes her self-defining process by driving off the bridge which Freud interprets as a way of giving birth. This paper helps understanding the ways in which society particularly family affect an individual’s decisions and the ways in which an individual tries to assert her/his will.

Authors: Nauman Ahmed Hafiz , Islam Muhammad
Published: April 2021

The study presents a corpus-based analysis of the influence of COVID-19 on the lexical features of English in Pakistan. News on Web Corpus (NOW), managed by English-Corpora.org, formerly known as BYU Corpora, with a specification of English language used in web news of more than 70 websites form Pakistan, was used data analysis. The section of the corpus of English in Pakistan news on the web contains approximately more than one billion words. The usage of 58 keywords, including the top 20 collocated words given by Oxford Dictionary (OED, 2020a), following COVID-19, from 2017 to 2019, was compared to 2020 till June 17, 2020. The analysis shows an exponential rise in the use of some new words and acronyms (e.g., self-quarantine, nCoV, and SARS). Many words that existed previously were used in media discourses to a great extent after COVID-19 (e.g., self-isolation, social-distancing, pandemic, and virus). Moreover, the trends in using such words are different in Pakistan from the trends in the other part of the World. The findings of the study may be used to expand the existing knowledge about language change, viewing coronavirus pandemic (and similar events) on the wheels of technology as another possible socio-psychological factor of language change.

Sperm cytology: Kernechtrot–picroindigocarmine stain and dog semen
Authors: Stern Adam
Published: April 2021

Animal sexual abuse cases present as an unusual scenario for forensic investigators. In this study, the kernechtrot–picroindigocarmine (KPIC, aka Christmas tree stain) staining properties of semen from 8 domestic dogs was compared to two samples of human sperm. In the head of the dog sperm, the acrosomal region stained pale red and the postacrosomal region stained dark red. There was a colorless band with a mean length of 0.59 μm within the sperm head between the acrosomal and postacrosomal regions. The colorless band was not identified within the human control samples nor reported in the literature. This data supports the use of KPIC stain for the examination of dog semen and further characterizes a unique staining pattern found in dog sperm that is not present in human sperm.
The growth of veterinary forensics
Authors: Stern Adam W
Published: April 2021

Veterinary forensics is a rapidly growing field, and it is recognized that there is a connection between animal abuse and other types of interpersonal violence (Lockwood and Arkow 2016). While all states have misdemeanor and felony statues for animal abuse, unfortunately, not all cases of animal abuse are reported to the authorities or investigated for a multitude of reasons. Some of these reasons include the lack of mandatory reporting laws in all states, an inability to perform a forensic postmortem examination in all suspicious death cases, lack of training on the identification and documentation of suspected animal abuse, and financial constraints. While it is possible to mitigate some limitations on the local level in some communities, much improvement is needed on the state and national scale.
Examining the effects of bodygrip 330 traps on domestic cat (Felis catus) cadavers
Authors: Kagan Rebecca , Elbert Jessica , Juriga Max
Published: April 2021

Bodygrip traps (also called Conibear traps) are nontoothed kill traps used for furbearers and nuisance wildlife. These traps pose a danger to nontarget animals, such as protected wildlife, domestic animals, and people, more so when used on dry land. Because of the potential for intentional or accidental misuse, diagnosis of bodygrip trap injuries may be of consideration in forensic casework. To determine whether trap-related injuries can be identified to narrow down or confirm the cause of death, standard 330 and Magnum 330 bodygrip traps were used on cadavers of 9 domestic cats (F. catus). Trap jaws were engaged in various locations on the bodies to simulate potential live entrapment situations. The cadavers were then imaged and necropsied. Trap-related damage was present only in one (1/9) cat and consisted of liver fractures, likely augmented by the presence of a full stomach. The remaining cats (8/9) had no grossly or radiographically visible injuries. Findings are consistent with past live animal studies in which trap-related injury was only rarely observed or documented. Because no specific injuries can be attributed to bodygrip traps, the diagnosis must rely on the circumstance and rule out other likely causes of death.

Published: April 2021

Considerando-se a importância de desenvolver uma fórmula de sorvete mais saudável para um público com restrição ao açúcar, optou-se pelo uso do adoçante estévia na elaboração de um sorvete de café, que tem propriedades antioxidantes, além de vitaminas, e o óleo de coco que também tem vários benefícios para a saúde. O objetivo deste trabalho é avaliar a aceitabilidade sensorial de um sorvete sabor café junto ao óleo de coco em substituição à gordura e a estévia como edulcorante. Foram formuladas três receitas de sorvetes: uma formulação padrão da fábrica de sorvetes Maipu, já testada, com textura, cremosidade e cor, apenas sem a melhoria do sabor e aroma do café, porém utilizou-se açúcar e gordura hidrogenada, com saborizante de café; a segunda foi substituído o açúcar pelo adoçante estévia, acrescentado o óleo de coco e mantido o mescla de café saborizante; já a terceira amostra foi formulada uma receita mais saudável com óleo de coco, estévia e café expresso. Estas 3 formulações de sorvetes foram submetidas à análise sensorial para atributos de cor, textura, sabor, aroma por meio de uma escala hedônica estruturada de nove pontos, com 50 provadores não treinados. Observou-se que a adição de 100% estévia, do óleo de coco e do café expresso, alterou significativamente a textura dos sorvetes testados e apresentaram melhor aceitabilidade com relação ao sabor agradável do café marcante.
THE IMPACT OF TRADE OPENNESS ON MANUFACTURING SECTOR PERFORMANCE
Authors: Neoh Sun Fu , Lai Tian So
Published: April 2021

Trade openness plays a vital role in boosting the production of the manufacturing sector. Two opposing perspectives identify trade-growth nexus. One posits that trade openness will stifle industrial productivity while the opposing view believes that manufacturing productivity can be enhanced by a trade liberalization regime. This study investigates the instantaneous and jointly dynamic effect of trade openness along with macroeconomic variables (i.e., Malaysian exchange rate and average lending rate) and the event of economic crises on manufacturing sector performance in Malaysia using data from 1981 to 2016. This study employed a distributed lag model. The Augmented Dickey-Fuller (ADF) unit root test was adopted to determine the stationarity of time series data. The empirical results revealed that the effect of both instantaneous and the jointly dynamic effect of the percentage change in trade openness on manufacturing production growth in Malaysia are positive and significant. However, the effects of the percentage change in exchange rate and percentage change in average lending rate are insignificant. Economic crisis has a significant negative impact on Malaysian manufacturing production growth. Therefore, the results strongly recommend that the direction of trade policy in Malaysia should be formulated based on outward-looking strategies.
A CRITICAL REVIEW OF THE LITERATURE ON THE CONCEPT OF JOB MISMATCH AND OVEREDUCATION
Authors: Shahidan Asnida , Ismail Russayani
Published: April 2021

Job-education mismatch and overeducation issues among graduates have been discussed extensively, specifically related to the incidents, determinants, methods of measurement, and the effects of the mismatch. Despite this, the concept of job-education mismatch itself is not clearly explained. Since understanding this concept has theoretical and practical implications, this paper provides a critical review of the job mismatch concept and relates it to overeducation, which is a type of job-education imbalance under a vertical mismatch. This study relies solely on the literature review and does not provide any empirical evidence related to these concepts. A few issues have been highlighted and worth considering for further deliberation. Firstly, even though job-education mismatch, overeducation, overqualification, and underemployment are interchangeably used, these concepts have quite a distinct meaning. Secondly, when individuals’ skills are considered in discussing vertical and horizontal mismatch, the scope of mismatch tends to be broader than that of overeducation. Thirdly, the discussion on overeducation tends to concentrate on the level of study imbalance and not on both the level and type of study. Fourthly, job-education imbalance by the field of study (horizontal mismatch) is not easily defined, and the discussion tends to be related to overeducation.

Incremental Search for Informative Gene Selection in Cancer Classification
Authors: Fajila Fathima , Yusof Yuhanis
Published: April 2021

Although numerous methods of using microarray data analysis for classification have been reported, there is space in the field of cancer classification for new inventions in terms of informative gene selection. This study introduces a new incremental search-based gene selection approach for cancer classification. The strength of wrappers in determining relevant genes in a gene pool can be increased as they evaluate each possible gene’s subset. Nevertheless, the searching algorithms play a major role in gene’s subset selection. Hence, there is the possibility of finding more informative genes with incremental application. Thus, we introduce an approach which utilizes two searching algorithms in gene’s subset selection. The approach was efficient enough to classify five out of six microarray datasets with 100% accuracy using only a few biomarkers while the rest classified with only one misclassification.
Remarks on the Behavior of an Agent-Based Model of Spatial Distribution of Species
Authors: Bioco João , Prata Paula , Cánovas Fernando , Fazendeiro Paulo
Published: April 2021

Agent-based models have gained considerable notoriety in ecological modeling as well as in several other fields yearning for the ability to capture the emergent behavior of a complex system in which individuals interact with each other and with their environment. These models are implemented by applying a bottom-up approach, where the entire behavior of the system emerges from the local interaction between their components (agents or individuals). Usually, these interactions between individuals and their enclosing environment are modeled by very simple local rules. From the conceptual point of view, another appealing characteristic of this simulation approach is that it is well aligned with the reality whenever the system is composed of a multitude of individuals (behavioral units) that can be flexibly combined and placed in the environment. Due to their inherent flexibility, and despite of their simplicity, it is necessary to pay attention to the adjustments in their parameters which may result in unforeseen changes on the overall behavior of these models. In this paper we study the behavior of an agent-based model of spatial distribution of species, by analyzing the effects of the model parameters and the implications of the environment variables (that compose the environment where the species lives) on the models’ output. The presented experiments show that the behavior of the model depends mainly on the conditions of the environment where the species live, and the main parameters presented in life cycle of the species.
The Hsp70 chaperone system: distinct roles in erythrocyte formation and maintenance
Authors: Mathangasinghe Yasith , Fauvet Bruno , Jane Stephen M. , Goloubinoff Pierre , Nillegoda Nadinath B.
Published: April 2021

Erythropoiesis is a tightly regulated cell differentiation process in which specialized oxygen- and carbon dioxide-carrying red blood cells are generated in vertebrates. Extensive reorganization and depletion of the erythroblast proteome leading to the deterioration of general cellular protein quality control pathways and rapid hemoglobin biogenesis rates could generate misfolded/aggregated proteins and trigger proteotoxic stresses during erythropoiesis. Such cytotoxic conditions could prevent proper cell differentiation resulting in premature apoptosis of erythroblasts (ineffective erythropoiesis). The heat shock protein 70 (Hsp70) molecular chaperone system supports a plethora of functions that help maintain cellular protein homeostasis (proteostasis) and promote red blood cell differentiation and survival. Recent findings show that abnormalities in the expression, localization and function of the members of this chaperone system are linked to ineffective erythropoiesis in multiple hematological diseases in humans. In this review, we present latest advances in our understanding of the distinct functions of this chaperone system in differentiating erythroblasts and terminally differentiated mature erythrocytes. We present new insights into the protein repair-only function(s) of the Hsp70 system, perhaps to minimize protein degradation in mature erythrocytes to warrant their optimal function and survival in the vasculature under healthy conditions. The work also discusses the modulatory roles of this chaperone system in a wide range of hematological diseases and the therapeutic gain of targeting Hsp70.

Os fatores de virulência cagA e vacA, estão intimamente relacionados a patogenicidade da Helicobacter pylori. Estes fatores são amplamente estudados e associados com um maior risco de desenvolvimento de diversos desfechos clínicos gastroduodenais, como o câncer gástrico. Além de apresentarem diversos polimorfismos genéticos, que podem variar de acordo com a região geográfica, acarretando em diferentes níveis de toxicidade e manifestações clínicas gástricas. Através de uma revisão integrativa da literatura analisou-se os estudos clínicos/epidemiológicos publicados entre 2015 e 2020, nas bases de dados LILACS, Scielo e PubMed, objetivando reunir os dados mais recentes e importantes sobre os diversos polimorfismos nos fatores de virulência cagA e vacA e os desfechos clínicos gastroduodenais. Foram identificados 19 estudos que contemplavam o objetivo desta revisão e foi observada uma grande variedade de polimorfismos e combinações genéticas destes fatores de virulência em associação com diversos desfechos clínicos. Notou-se também, a existência de perfis genéticos de prevalência das cepas de H. pylori e associações com as patologias gástricas distintas em certas regiões geográficas. Apesar de identificados alguns resultados conflitantes, a compreensão destes achados e a identificação dos possíveis genes contribuintes nas patologias gástricas, podem servir como marcadores para o desenvolvimento de estratégias para a prevenção dessas patologias e melhor eficácia do tratamento.

Викладені основні результати натурного інструментального обстеження адміністративної будівлі в м. Києві. Первісна проектна документація на будівлю за давністю не збереглася. При обстежені виявлено розкол у товщі кладки вздовж несучої цегляної зовнішньої стіни в рівні 1-го поверху. Два простінки внаслідок пошкоджень повністю втратили несучу здатність, повне їх руйнування не відбувається тільки за рахунок перерозподілу зусиль на сусідні простінки, поперечні стіни, перегородки тощо. Простінки несучої зовнішньої стіни, які зазнали пошкоджень, складені з різних матеріалів (кладка з жовтої цегли і кладка з червоної цегли). Визначені показники міцності матеріалів комплексної кладки стін: жовта керамічна цегла в кладці обрамлення віконних прорізів за міцністю на стиск відповідає марці 75; червона керамічна цегла в кладці простінків – марці 35. Пошкоджена частина стіни має вигин в бік вулиці. Для визначення геометричних параметрів вигину зовнішньої поверхні стіни були виконані вимірювання поздовжнього профілю стіни в трьох рівнях. Виявлено, що у рівні над карнизом стіна практично прямолінійна. В той же час, безпосередньо під карнизом горизонтальні зміщення стіни назовні складають до 68 мм. На рівні цокольного пояска зміщення стіни назовні складають до 20 мм. Проведені розрахунки міцності елементів несучих стін, згідно з якими несуча здатність не забезпечується, значення коефіцієнтів перевантаження сягають до k = 1,402 > 1. Проаналізовані результати багаторічного моніторингу вертикальних осідань будівлі. Характер руйнування простінків і підкарнизної ділянки стіни 1-го поверху обумовлений конструкцією цієї стіни. Руйнування стіни в рівні 1-го поверху відбулося шляхом утворення вертикальних поперечних тріщин у простінках по межі кладки обрамлення вікон з жовтої цегли, а також утворення поздовжнього розриву простінків та надвіконної частини стіни з загальною орієнтацією між концентраторами напружень – кут над карнизом, де відбувається зміна товщини стіни, і підвіконними нішами. На підставі результатів обстеження та розрахунків встановлені причини аварійного стану стіни. Був зроблений висновок, що всі простінки стін 1-го поверху потребують підсилення, з врахуванням перевантаження за розрахунком, також рекомендоване підсилення простінків стін 2-го поверху. Надані рекомендації щодо підсилення несучих стін будівлі при пошкодженні у вигляді поздовжнього розколу.
ВИПРОБУВАННЯ ФРАГМЕНТУ ВЕНТИЛЬОВАНОЇ УТЕПЛЕНОЇ ФАСАДНОЇ СИСТЕМИ З АЛЮМІНІЄВИМ КАРКАСОМ І ОПОРЯДЖЕННЯМ ПЛИТАМИ ПРИРОДНОГО КАМЕНЮ

Розглянуто результати експериментальних досліджень роботи енергозберігаючої фасадної вентильованої системи Hilti з прихованим кріпленням плит опорядження природного каменю на каркасі з алюмінієвих елементів за допомогою аграфів. Зразок фрагмента фасадної системи розмірами 4×2 м випробували на стенді в горизонтальному положенні на комплексну дію власної ваги, обледеніння та вітру від розрахункових навантажень експлуатаційних і граничних, позитивних і негативних, в рядовій і кутовій зонах будівлі. Наведені розрахунки навантажень, випробувальне обладнання, схеми випробувань та схеми розміщення вимірювальних приладів. Визначено фізико-механічні характеристики природного каменю плит опорядження. Опорядження випробуваного зразка складали 4 плити розмірами 2035×890×30 мм, масою по 122,5 кг. Визначено величини деформацій опорядження та представлено їх вичерпний аналіз. Руйнівне навантаження в площині плит становило 46,6 кН, що відповідає висоті будівлі 27 м. Характер руйнування зразка – деформація аграфів із вертикальним переміщенням та з розривом з’єднання направляючого аграфного профілю з несучим. Хімічні анкери плит опорядження витримали без пошкодження на вирив вітрове від’ємне навантаження 0,652 кН та на зріз вертикальне навантаження 1,664 кН. Випробуваннями зразка фрагменту фасадної системи встановлено, що система витримала всі передбачені види навантажень експлуатаційних і граничних від власної ваги, двостороннього зледеніння облицювання, вітрового навантаження позитивного і негативного на рядових і кутових ділянках. Під час проектування, монтажу та експлуатації цієї фасадної системи слід враховувати її вразливості: масивність опорядження, надійність з’єднань несучих і аграфних профілів каркасу та самих аграфів, можливість конструктивного забезпечення від зледеніння горизонтальних проміжків між плитами на рівні поверхів.

The skin is an attractive alternative administration route for allergy vaccination, as the skin is rich in dendritic cells (DCs) and is easily accessible. In the skin multiple subsets of DCs with distinct roles reside at different depths. In this study antigen (=allergen for allergy) formulations were injected in ex vivo human skin in a depth-controlled manner by using a hollow microneedle injection system. Biopsies were harvested at the injection site, which were then cultured for 72 h. Subsequently, the crawled-out cells were collected from the medium and analyzed with flow cytometry. Intradermal administration of ovalbumin (OVA, model antigen) solution at various depths in the skin did not affect the migration and maturation of DCs. OVA was taken up efficiently by the DCs, and this was not affected by the injection depth. In contrast, Bet v 1, the major allergen in birch pollen allergy, was barely taken up by dermal DCs (dDCs). Antigens were more efficiently taken up by CD14+ dDCs than CD1a+ dDCs, which in turn were more efficient at taken up antigen than Langerhans cells. Subsequently, both OVA and Bet v 1 were formulated in cationic and anionic liposomes, which altered antigen uptake drastically following intradermal microinjection. While OVA uptake was reduced by formulation in liposomes, Bet v 1 uptake in dDCs was increased by encapsulation in both cationic and anionic liposomes. This highlights the potential use of liposomes as adjuvant in intradermal allergy vaccine delivery. In conclusion, we observed that antigen uptake after intradermal injection was not affected by injection depth, but varied between different antigens and formulation.
