An Embedded 5(4) Pair of Optimized Runge-Kutta Method for the Numerical Solution of Periodic Initial Value Problems
Authors: Fawzi Firas. A. 
Published: October 2022

This paper presents an alternative method for developing effective embedded optimized Runge-Kutta (RK) algorithms to solve oscillatory problems numerically. The embedded scheme approach has algebraic orders of 5 and 4. By transforming second-order ordinary differential equations (ODEs) into their first-order counterpart, the suggested approach solves first-order ODEs. The amplification error, phase-lag, and first derivative of the phase-lag are all nil in the embedded pair. The alternative method’s absolute stability is demonstrated. The numerical tests are conducted to demonstrate the effectiveness of the developed approach in comparison to other RK approaches. The alternative approach outperforms the current RK methods.

Published: October 2022

Methicillin resistant Staphylococcus aureus (MRSA) is the most common pathogenic bacteria in the hospitals and communities, the ability to form biofilm is considered the main cause of Staphylococcus pathogenicity since it provides resistance to both antibiotics and host immune response, so this study was aimed to evaluate the biofilms formation and its association with antibiotic resistance in clinical isolates of MRSA, in order to achieve this aim, 237 samples were collected from different patients with wounds infections after surgeries and samples from operations galleries from varies hospitals in Baghdad ,68 isolates out of 237 were subjected to Staphylococcus aureus according to conventional methods Additionally, the S. aureus isolates were re-identified by molecular method. The results for Susceptibility of 68 S.aureus isolates against 22 antimicrobial agents revealed all isolates were resistant (100%) to Cefotaxime, and showed resistance to Ceftriaxone, Oxacillin, Cefipime, Cefoxitin, ampicillin, Penicillin, Nalidixicacid, erythromycin in percentage (99, 97,97,87, 87, 79, 75, 65 )% respectively while other isolates showed variety in their resistant to other antimicrobial agents. while all 68 isolates were sensitive to Nitrofurantoin which is considered the most effective agent against the isolates. All 68 isolates were identified as MRSA on HiCromeMeReSa Agar Base medium, but 66 among 68 isolates were methicillin resistant in antibiotic sensitivity test, while 67 isolates had a positive reaction when detecting mecA gene using Polymerase Chain Reaction (PCR) technique. The finding of biofilm detection by microtiter plate method (MTPs) showed that 56 of 68 isolates produced biofilm in different degrees, while 66 (97%) among 68 isolates possessed the icaAD gene using PCR.

Published: October 2022

This research evaluates the optical properties of an inhomogeneous and non-paraxial system using a solar ball lens (SBL) as a new thermal solar concentrated collector. This evaluation is based on detecting a diacaustic curve in a straightforward and accurate manner, with the diagnostic relying on image processing as a computational tool using the MATLAB program rather than a complicated numerical analytic procedure. The circle of least confusion (CLC) of the (SBL), (Fluorinated ethylene propylene (FEP) polymer – water core), was calculated. Furthermore, the study evaluated the maximum geometrical concentration ratio (G C) of refracted solar radiation that can be captured by a receiver of the (SBL). Without energy losses due to spherical aberration, the (G C) ratio was (14.10) at (h/r) ratio, circular aperture radius to ball radius, around (0.6). The investigation also revealed an aplanatic point for preventing the development of optical envelope inside the solar ball lens at (h/r) equal to 0.8638, as well as a maximum (h/r) value of 0.7351 for collecting solar radiation.

Introdução: A violência contra à mulher é caracterizada especialmente pela desigualdade de gênero, diferença hierárquica, subordinação e pela agressividade do parceiro ou ex-parceiro. Entre os principais subtipos, cita-se; a violência física, psicológica, sexual, patrimonial e moral. Com o surgimento da pandemia de coronavírus em 2020 na tentativa de contenção da doença, medidas protetivas como o isolamento social aumentaram o convívio familiar. Dessa forma, as vítimas de violência passaram a ficar ainda mais tempo expostas aos seus agressores e consequentemente com maiores dificuldades para denunciar os abusos sofridos, pois a prestação dos serviços públicos, instituições de segurança e judiciais também foram restringidas. Objetivo: Caracterizar os casos de violência contra a mulher em tempos de pandemia de coronavírus em um município do Sudoeste do Paraná. Materiais e métodos: Trata-se de um estudo descritivo, documental e transversal com abordagem quantitativa realizada em um município do Sudoeste do Paraná a partir da coleta de dados, por meio das fichas de notificação de violência contra a mulher entre 2019 e 2021. Resultados e discussão: O estudo demonstrou prevalência de notificações no ano de 2019 em mulheres com idade de 12 a 18 anos (27,2%), brancas (71,3%), com ensino médio (21,9%), sendo ainda estudantes (23,1%) ou desempregadas (17,2%), sem companheiro (52,4%), residentes da área urbana (74%), heterossexuais (50,6%), sem possuir algum tipo de deficiência (51,8%). Ao verificar a tipologia da agressão com maior incidência, observou-se a lesão autoprovocada (53,6%) por meio da intoxicação /envenenamento (41,4%). Quanto a violência interpessoal, notou-se que a maioria das agressões foram ocasionadas pelo próprio cônjuge da vítima (12,4%), utilizando da força física (29,3%), salienta-se que o álcool não estava presente na maior parte das agressões. Conclusão: Evidencia-se a prevalência de violência autoprovocada (53,6%), em adolescentes com ensino médio, brancas, sem companheiro, residentes da área urbana, agredidas em ambiente domiciliar, motivadas por conflitos geracionais, sendo as violências mais incidentes a física por meio de envenenamento/intoxicação. Diante do exposto é importante abordar o fato de que é necessário realizar capacitações com os profissionais de saúde referente a ficha de notificação e orientá-los da importância de preenchê-la de forma correta, para haja a tomada de providências de acordo com cada necessidade.

O objetivo deste estudo foi comparar os desfechos clínicos dos pacientes em suporte ventilatório invasivo por período curto e prolongado e correlacionar funcionalidade e tempo de ventilação mecânica (VM). Estudo documental retrospectivo, realizado na UTI neurocirúrgica de um hospital escola. Dos prontuários clínicos foram coletados: idade, sexo, hipótese diagnóstica de internação, tempo de internação e de VM em dias, o desfecho sucesso ou falha da extubação e o nível de funcionalidade. Os prontuários foram divididos em grupo um (GI): pacientes em VM por até três dias e grupo dois (GII): pacientes em VM por mais de três dias. Foram analisados 210 prontuários, 73% dos pacientes permaneceram menos de três dias em VM. A idade média de GI foi 51,8±15,5 anos e GII 48,7±16,3 anos (p=0,20), prevalência do sexo masculino em GI (59%) e GII (68%). O acidente vascular cerebral foi o diagnóstico mais prevalente no GI (18%) e o tumor cerebral no GII (21%) e hipertensão arterial, a comorbidade mais prevalente em GI (28%) e GII (25%). O GII permaneceu maior tempo (p<0,0001) em VM e internação na UTI que o GI e percentual de sucesso no desmame/extubação menor (p=0,01) que o GI. Não houve correlação significativa entre funcionalidade e tempo de VM em GI e GII (p>0,05). Os pacientes em suporte ventilatório invasivo por período prolongado evoluíram com maior permanência em VM, maior tempo de internação na UTI e menor taxa de sucesso no desmame/extubação. O tempo de permanência em suporte ventilatório invasivo não interferiu na funcionalidade desses pacientes.

Description. Coffee cultivation plays an important economic and social role in Côte d'Ivoire. Among the dozens of Coffea species, only Coffea canephora, also known as robusta, is grown in the country. The genetic improvement of this species has been the subject of a selection program set up by the National Center for Agronomic Research (CNRA). This program involves two basic genetic groups, Guinean and Congolese. These groups have been determined using enzymatic markers which are known to be less informative. So little is known about the reliability of the genetic structuring of the parental populations. Objectives. The objective of this work is to refine the genetic structuring of the parental populations used to set up the C. canephora breeding program in Côte d'Ivoire using SNP markers and to relate this structure to test values in the genotypes concerned. Method. Sixty-six individuals representing parental genotypes of the two populations were analyzed using 200 SNPs markers. The parameters of genetic diversity were calculated and then the genetic structure was determined. The yield over four years of production, susceptibility to rust, and bean size have been evaluated. Results of these agronomic traits have been included in this analysis. The Guinean genotypes were crossed with a Congolese tester named 464 and the Congolese individuals were crossed with a Guinean tester 410, for assessing their combining ability. Results. The analysis of molecular variance (AMOVA) revealed that 75% of the total variation was due to variation between populations. Bayesian classification and Principal Coordinates Analysis (PCoA) structure the 66 genotypes into two main groups of Guineans and Congoleses. While the Guinean group appears to be homogeneous, the Congolese group is split into four subgroups of SG1, SG2, B and C. Maximum test values are found for the SG1 and SG2 subgroups. The Guinean group showed lower performance. It is important in this group to select the best progenitors. Conclusions. SNP markers were effective in genetic structuring of the population. This study also allows the identification of a genotype that was not determined. The use of this set of markers will be useful for the control of future progenitors. The same genetic progress can be achieved by crossing SG1 or SG2 with a good Guinean male. It seems important to make a selection among the Guineans before crossing them with a Congolese tester.

Данные материалы базируются на аналитической оценке результатов исследований, представленных на 26-м Генеральном собрании Европейской федерации луговодов, состоявшемся в Норвегии в 2016 году. Климатические изменения и их влияние на луговые травяные системы от Средиземноморья до северных регионов Европы стали одной из центральных проблем, рассматриваемых на форуме. В то время как продуктивность систем Средиземноморского региона становится из-за засухи всё более ограниченной, системы в северных регионах могут оказаться в более благоприятных условиях, хотя возникает ряд особенностей, касающихся возможностей их использования, которые связаны с удлинением вегетационного периода, влиянием избыточного увлажнения и др. В обоих регионах климатические изменения приведут к модификации ежегодных продукционных циклов, которая потребует адаптации сельхозтоваропроизводителей к режиму заготовки кормов и использования пастбищ. Агроэкосистемы с включением бобовых могут реагировать на повышение содержания углекислого газа лучше, чем многие другие культуры. Селекционные усилия должны быть направлены как на улучшение растений с целью повышения устойчивости к абиотическим стрессам, так и на адаптацию к новым сезонным изменениям и системам управления, обеспечивающим продуктивность.
The information of this paper is based on analytical evaluation of the results, presented at 26th General Meeting of European Grassland Federation, taken place in 2016. Climate change and its influence on grassland systems from Mediterranean to Northern Europe received a considerable attention at the meeting. While productivity of Mediterranean ecosystems reduces due to drought, northern vegetation may happen to be under more favorable conditions. However the number of new aspects appears, which are related to grass utilization under longer growing season, excessive humidity etc. In both regions climate change will result in modification of annual production cycles, requiring adjustment of farmers to regimes of fodder preparation and grassland cultivation. Agroecosystems, containing legumes may respond to the increase of carbon dioxide better than other crops. Breeders must focus on development of crops, having higher resistance to abiotic stress as well as crop adaptation to new seasonal changes and management systems, responsible for productivity.
TALE E QUALE, OR NOT REALLY?

In November 2020, on the Italian national television broadcast Tale e quale show (TQS), participant Sergio Muñiz imitated Tunisian-Italian rapper, Ghali, with a performance that received backlash from Ghali himself because of its use of blackface. This is not the first time that blackface was used on TQS, but the first time that it was used to imitate an Italian artist. In this paper, I analyze what implications this performance has from the perspectives of Cultural Studies, History, and Critical Race and Ethnic Studies. I argue that the performance invokes Mediterranean Whiteness to differentiate North-Mediterranean populations from their racialized South-Mediterranean ‘Others’.
OPTIMALISASI NILAI ILUMINASI DENGAN SKYLIGHT DAN MATERIAL TRANSPARAN UNTUK BANGUNAN DERET-BERTINGKAT PADA RUKO GAIA DI AYODHYA, ALAM SUTERA, TANGERANG
Authors: Devina D Felisitas , Mandala Ariani 
Published: October 2022

Abstrak - Bangunan deret-bertingkat seperti ruko (rumah-toko) memiliki permasalahan dalam mengakomodasi kebutuhan pencahayaan alami akibat tipologi bangunan yang linear, keterbatasan untuk membuat bukaan samping, dan terdiri dari dua lantai atau lebih. Tipologi bangunan demikian menghasilkan distribusi cahaya yang tidak merata, terutama pada bagian tengah ke belakang bangunan dan lantai-lantai selain lantai teratas.
Salah satu upaya untuk memasukkan cahaya alami atau daylight ke dalam bangunan ruko yang bentuknya memanjang adalah dengan menggunakan bukaan atas (top lighting). Namun keberadaan bukaan atas pun tidak memungkinkan untuk menerangi lantai selain lantai teratas dari bangunan ruko akibat terhalang permukaan lantai. Material transparan seperti kaca memungkinkan transmisi cahaya yang lebih tinggi daripada material opaque, sehingga dengan menggunakan material kaca dapat meningkatkan iluminasi pada ruang di balik kaca tersebut.
Tujuan studi ini adalah untuk mengkaji kesesuaian tingkat iluminasi pada desain pencahayaan alami Ruko Gaia terhadap nilai Daylight Factor (DF), Spatial Daylight Autonomy (sDA), dan Annual Sunlight Exposure (aSE) sesuai standar BREEAM dan IES LM-83-12, mengkaji pengaruh perubahan posisi skylight-tangga dan penggunaan material transparan pada bidang lantai-tangga terhadap tingkat iluminasi, serta melakukan optimalisasi desain untuk meningkatkan nilai DF sesuai standar yang digunakan.
Penelitian diawali dengan melakukan evaluasi pada desain pencahayaan alami Ruko Gaia. Dengan melakukan simulasi alternatif, kemudian akan dilakukan pengkajian pengaruh perubahan posisi skylight-tangga dan penggunaan material transparan pada bidang lantai-tangga terhadap tingkat iluminasi. Apabila tingkat iluminasi yang dihasilkan belum mencapai standar yang ditentukan, dilakukan optimalisasi dengan pengingkatan nilai Visible Light Transmittance (VLT) atau penambahan dimensi skylight.
Metode yang digunakan adalah metoda kuantitatif berupa evaluasi desain perencanaan dan simulasi alternatif. Teori-teori maupun data Ruko Gaia dikumpulkan dari studi literatur, website, brosur, maupun pihak agen properti, serta pengolahan data simulasi dengan software SketchUp dan Lightstanza.
Berdasarkan evaluasi, tingkat iluminasi pada Ruko Gaia belum memenuhi standar BREEAM dari nilai DF dalam kondisi langit overcast, terutama pada lantai dasar. Berbagai studi alternatif menghasilkan kesimpulan bahwa walaupun meningkatkan nilai DF, perubahan posisi tangga-skylight dan penggunaan lantai-tangga transparan belum menghasilkan nilai DF yang sesuai standar BREEAM. Optimalisasi nilai DF dapat dicapai dengan meningkatkan nilai VLT atau memperbesar dimensi skylight.

Abstrak - Sekolah Alfa Omega merupakan sebuah sekolah yang memiliki desain merespon alam. Strategi desain dibuat sedemikian sehingga secara konsep desain, menjawab permasalahan iklim di tempat sekolah itu dibangun. Berlokasi di area yang memiliki iklim tropis, dengan lebih spesifiknya area rawa dan persawahan, membuat iklim di sekitar tempat tersebut terasa kurang nyaman dengan temperatur udara yang cukup tinggi dan tingkat kelembapan udara yang berada di atas tingkat kenyamanan termal untuk beraktivitas.
Sekolah tersebut didesain dengan melakukan pengolahan pada kulit bangunannya. Raw Architect selaku pihak yang mendesain sekolah ini, memilih material bata dengan alasan utama mengangkat lokalitas yang berada pada kawasan tersebut. Selain itu, dengan menggunakan material bata sebagai bagian dari elemen arsitektural di dalam bangunan tersebut, maka mereka dapat seminimum mungkin menciptakan jejak karbon, yaitu emisi dari kegiatan manusia yang dalam waktu lama akan menimbulkan dampak negatif kepada alam, dimana ini berarti mereka dapat menciptakan desain yang tidak hanya mengangkat lokalitas tetapi juga ramah lingkungan.
Tujuan dari penelitian ini adalah untuk melihat apakah pengaruh dari dinding dengan susunan bata berongga dalam desain selubung bangunan ruang terhadap kenyamanan termal yang coba dibuat di dalam desain Sekolah Alfa Omega.Penelitian merupakan penelitian dengan jenis evaluatif – eksperimental dengan pendekatan kuantitatif dengan cara mendeskripsikan keadaan dan kondisi baik dari segi arsitektural, maupun segi kenyamanan termal yang ada lalu dibandingkan dengan teori mengenai kenyamanan termal secara umum dan secara lebih khusus sebagai sebuah sekolah. Penelitian ini dilakukan secara tidak langsung melalui media komputer, internet, serta program simulasi untuk melakukan pengukuran tingkat kenyamanan termal pada Sekolah Alfa Omega.
Hasil dari penelitiannya adalah pemahaman akan bagaimana pengaruh dari dinding dengan susunan bata berongga sebagai sebuah selubung bangunan dalam menanggapi iklim yang ada di daerah tersebut, sehingga dapat dipahami bagaimanakah kemampuan dari dinding ban dalam selubung ruang dalam mencapai kenyamanan termal yang dapat mendukung aktivitas di dalamnya sebagai sebuah sekolah. Dan apabila ditemukan ketidaknyamanan termal pada aplikasi material tersebut sebagai selubung bangunan, maka akan dicari cara untuk mengoptimalkan kualitas termal nya dengan teori-teori dan eksperimen simulasi.
