Published: June 2019

<p> The present study aims to evaluate the control of C. benghalensis by herbicides applied in post-emergence and in pre-emergence sequentially in the infesting weed in the coffee crop. Two field experiments were carried out in a coffee crop, with natural infestation of C. benghalensis, the experimental design of both was completely randomized with 4 replicates. The first experiment, involving a single application of herbicides in post-emergence presented the following treatments: (1) saflufenacil (70 g i.a. ha-1); (2) glufosinate (400 g i.a. ha-1); (3) carfentrazone (20 g i.a. ha-1); (4) flumioxazin (120 g i.a. ha-1); (5) metsulfuron (6 g i.a. ha-1), and (6) witness (without application of herbicide). In the second experiment, the treatments were: (1) saflufenacil (70 g i.a. ha-1); (2) carfentrazone (20 g i.a. ha-1); (3) flumioxazin (120 g i.a. ha-1); (4) metsulfuron (6 g i.a. ha-1), all these treatments with a sequence of indaziflam (75 g i.a. ha-1), at 21 days after the application of the treatments (DAT) of pos-emerging; (5) Witness (without application of herbicides). In the first experiment the herbicides safluenacil and flumioxazin presented the best percentages of control in post-emergence with 90 and 85.25% respectively, at 7 DAT, keeping the control superior to 80% at 21 DAT. In the second experiment, the treatments saflufenacil and flumioxazin with indaziflam sequential, presented control of 80% and 82.5% respectively at 28DAA (Days After Application). The herbicides saflufenacil and fluxioxazin represent an option for the control of C. benghalensis in post-emergence and favor the performance of the sequentially applied indaziflam herbicide. </p>
É A FAVELA O MODELO DE UM "URBANISMO INSURGENTE"? PISTAS PARA UM ESTUDO DAS FORMAS DISCIPLINAR E SECURITÁRIA DE PRODUÇÃO DO ESPAÇO URBANO DE SALVADOR (1946-1988)
Authors: Nascimento Jùnior Manoel Maria do 
Published: June 2019

Tendo como base a distinção entre formas disciplinares e securitárias de exercício da soberania, tal como conceituadas por Michel Foucault, este artigo pretende, a partir de uma revisão bibliográfica sobre o processo de formação do território urbano de Salvador no século XX, responder às seguintes questões: é a favela um "urbanismo insurgente"? Pode a favela constituir uma alternativa ao urbanismo oficial? Em que medida a ação dos invasores, dos "favelados", compromete este urbanismo oficial? E em que medida o reforça? Conclui-se que: a) Sim, pode ser um “urbanismo insurgente” desde que considerada como expressão dos fenômenos da ocupação de terra urbana por massas proletárias e como conjunto de ações mais ou menos descoordenadas de sujeitos coletivos diversos; b) As invasões e favelas, sendo parcelares, não constituem uma alternativa global ao urbanismo e ao planejamento urbano oficiais, mas a proliferação de invasões e favelas num tempo histórico curto pode indicar que as muitas ações individuais e coletivas formadoras das invasões e favelas ofereceram um sentido alternativo ao desenvolvimento urbano da cidade.
ABERTURA, MANUTENÇÃO E FECHAMENTO DA CASA DE SAÚDE SANTA TERESA: TRAJETÓRIA MANICOMIAL DO CARIRI CEARENSE

Published: June 2019

<p>A história da loucura no Brasil é indissociável da história dos hospitais psiquiátricos, uma vez que a organização das cidades e sua higiene, pautadas nos moldes franceses do século XIX, dependiam dessas instituições para a manutenção da ordem social. A região do Cariri cearense contou com a existência de um hospital psiquiátrico (Casa de Saúde Santa Teresa) que funcionou a partir da década de 1970. Sua inauguração não foi uma aleatoriedade, mas fruto de formações discursivas específicas e relações de saber e poder que constituíram o alicerce para que o hospital abrisse suas portas na região, bem como para se manter em funcionamento até os dias atuais. A Casa de Saúde Santa Teresa foi uma instituição privada, credenciada inicialmente ao Instituto Nacional de Previdência Social e posteriormente ao SUS, recebendo financiamento público. Sua localização geográfica favoreceu o atendimento às pessoas da região do sul do Ceará, mas também do interior dos estados de Pernambuco, Paraíba e Piauí. Até fechar contou com 200 leitos cadastrados ao SUS, atendeu em regime ambulatorial e de internamento para uma média de 400 pessoas/mês. Apesar do intenso fluxo de atendimentos e se tratar da única referência para atendimentos de urgência, emergência e para situações de crise, o hospital encerrou seus anos de funcionamento em fevereiro de 2016. Segundo dados da Casa de Saúde, não havia aumento no valor das Autorizações de Internação Hospitalar (AIHs) desde o ano de 2009, o que tornava inviável a manutenção e funcionamento do hospital. </p>
The Relationship between Corpus Callosum Morphometric Measurements and Age/Gender Characteristics: A Comprehensive MR Imaging Study
Authors: Arda Kemal Niyazi , Akay Sinan 
Published: June 2019

Objective:
The objective of the study was to examine a possible relationship between morphometric corpus callosum (CC) measurements, age, and gender characteristics using MR images.

Materials and Methods:
The medical data and MR examinations of 436 consecutive subjects were retrospectively reviewed. The CC thickness from five different sites, and additionally splenium length, height, and total length of the CC, and the splenium index (SI) were measured with a mid-sagittal T1-weighted sequence. Those measurements were compared with age and gender characteristics.

Results:
A weak but statistically significant negative correlation was found between age and thicknesses of genu and all body portions of CC (P = ≤0.001 for all, r = -0.32 for genu, r = -0.317 for B1, r = -0.328 for B2, r = -0.328 for B2, and r = -0.194 for B3 and B4). There was a weak but statistically significant positive correlation between age and the lengths of CC and splenium (P ≤ 0.022 for both, r = 0.112 for CC length and r = 0.11 for splenium length). The second part of the body (B2) was thicker in females (P = 0.014). On the other hand, the CC and splenium lengths were greater in males compared to females (P = 0.029 for both).

Conclusion:
We designed a comprehensive MRI study to investigate a possible relationship between normal morphometric CC measurements in 436 healthy subjects. We preferred splenium length and SI as the main splenium measurements instead of direct splenium thickness, due to discrepancies regarding splenium measurement methods in the medical literature. There was a wide spectrum of results, and we compared those results with existing medical literature.
A RELATIVE ASSESSMENT OF THE CONTRIBUTIONS OF AGRICULTURE, OIL AND NON-OIL TAX REVENUES TO NIGERIA’S ECONOMIC EXPANSION
Authors: OMODERO Cordelia Onyinyechi 
Published: June 2019

The decline in oil prices globally has led to diversification of economy in most oil enriched countries. In Nigeria, more attention is given to agriculture and non-tax revenue sources to ensure that the country overcomes a mono-economy syndrome which has affected the nation in the past. This study assesses the contributions of agriculture, oil and non-oil tax revenue to economic expansion in Nigeria using data that cover a period from 1981 to 2017. The regression results indicate that oil revenue has a significant negative impact on economic growth which is represented by gross domestic product. On the contrary, the study finds evidence that agriculture and non-oil tax revenue have a robust significant and positive influence on economic growth. Therefore, the study suggests that tax administration in Nigeria should be more business-growth conscious and that agriculture should be given a boost by creating an enabling environment that could attract foreign direct investments in the agricultural sector. The study also recommends that oil revenues should be utilized for reinvestments into other sectors of the economy. Keywords: Oil revenue, non-oil tax revenue, agriculture, economic growth, Nigeria.JEL Classifications: H27, H24, H25, N5, O4

Potensi Rancang Bangun Platform Tepi/Lepas Pantai Untuk Pembangkit Listrik Tenaga Gelombang Laut Berbasis Material PZT (Piezoceramics)
Authors: Nugroho Wibowo Harso 
Published: June 2019

Krisis energi listrik telah menghampiri Indonesia, oleh sebab itu perlu dipikirkan sumber energi baru yang tepat, berlimpah dan terbarukan. Salah satu pilihan terbaik untuk negeri kepulauan ini adalah energi gelombang laut. Penulisan ini menggambarkan potensi dari sistem penghasil tenaga listrik yang ramah lingkungan dengan menerapkan pemakaian keping – keping Piezoceramics ( Lead Zirconate Titanate / PZT) pada fix platform di pantai / lepas pantai untuk nantinya secara langsung akan mengkonversi beban gelombang menjadi energi listrik yang akan disimpan kedalam sejumlah baterei dimana selanjutnya dapat di distribusi ke darat. Hal ini mungkin dilakukan karena material PZT ini akan menghasilkan beda potensial jika diberi gaya mekanik. Konsep dari pembangkit listrik ini adalah jika gelombang datang buoy bola baja tersebut akan terseret menghantam platform sehingga muncul gaya impak berupa pulsa stress pada struktur platform dan menghasilkan regangan pada keping – keping PZT yang terpasang dengan demikian tentunya akan menghasilkan medan listrik yang selanjutnya dapat didistribusi langsung melalui jaringan atau disimpan pada baterai yang telah dipersiapkan.

Published: June 2019

Problem getaran kapal saat ini semakin kompleks dan sering terjadi ditambah pula semakin ketatnya persyaratan dari biro klasifikasi kapal untuk tingkat getaran yang diijinkan agar penumpang dan awak kapal semakin nyaman dan aman. Secara umum getaran yang berlebih dapat mempercepat kelelahan struktur kapal, juga menyebabkan kerusakan atau tak berfungsi dengan baik peralatan mekanik dan listrik yang terdapat di atas kapal serta berkurangnya kenyamanan penumpang dan awak kapal. Salah satu metode untuk mengurangi pengaruh getaran struktur kapal adalah dengan melakukan pengurangan terhadap respon dari getaran tersebut dengan menggunakan peredam(damper). Pada paper ini dijelaskan metode penentuan koefisien redaman(damping) getaran dari peredam berbahan semen pelapis plat dek kapal di laboratorium uji getaran. Pengujian dilakukan dengan menggunakan martil impak (impact hammer) dan respon plat diukur oleh accelerometer. Secara umum sifat – sifat bahan pelapis ini tetap melekat pada material utama pembangunnya yaitu beton atau “ concrete” hal ini diperlihatkan dari nilai koefisien redaman (ζ) yang diperoleh pada uji getaran yaitu untuk material Deck Screed (DS) ~ 0.083482 dan Deck Compound (DC) adalah ~ 0.083182. Nilai koefisien redaman ini sedikit lebih tinggi dari rata – rata koefisien redaman dari bahan semen coran dengan penguatan ( Reinforced Concrete Structure) pada umumnya yaitu berkisar antara 0,04 – 0,07
ANALISIS KOMPARATIF HAMBATAN KAPAL KATAMARAN PADA PERAIRAN DANGKAL, MEDIUM DAN DALAM
Authors: Suwarni Endah , Pria Utama I Ketut Aria 
Published: June 2019

Berbagai literatur menunjukkan bahwa kapal katamaran menjadi populer dan sukses digunakan sebagai moda transportasi karena tersedianya area geladak yang lebih luas dan tingkat stabilitas yang lebih aman dan nyaman. Kapal katamaran mempunyai sarat rendah, memungkinkan untuk dioperasikan di perairan dangkal (shallow water) seperti halnya di perairan Indonesia yang relatif dangkal antara lain pelabuhan dan sungai. Di sisi lain hal tersebut dapat menimbulkan efek dan fenomena squat yang meningkatkan hambatan total kapal katamaran. Paper ini mengkaji hambatan lambung katamaran terhadap variasi kedalaman perairan. Eksperimen dilakukan di Tangki Tarik (Towing Tank) Jurusan Teknik Perkapalan (JTP) ITS dengan variasi rasio jarak antar lambung kapal – panjang kapal (S/L) 0.2 ~ 0.4 dan variasi kecepatan pada angka Froude (Fr) 0.25~0.42 di perairan dangkal dan medium serta dibandingkan dengan penelitian yang telah dilakukan sebelumnya pada perairan dalam, sehingga dapat memberikan komparasi hambatan total kapal katamaran di perairan dangkal, perairan medium dan di perairan dalam. Hambatan kapal katamaran yang cenderung meningkat di perairan dangkal dan medium pada kecepatan Fr 0.25~0.37 akibat terjadinya perubahan tekanan dan kenaikan kecepatan aliran antara bagian bawah badan kapal dan dasar perairan. Hal tersebut dapat memberikan kontribusi data untuk mengevaluasi prediksi hambatan total kapal katamaran, sehingga penentuan daya mesin kapal dan efisiensi bahan bakar kapal katamaran yang dioperasikan di perairan dangkal-medium dapat menjadi lebih optimal

Published: June 2019

INTRODUÇÃO: Diversos estudos têm demonstrado existir uma perturbação do processamento emocional em crian-ças com perturbação hiperatividade/ défice de atenção (PHDA). No entanto, existem poucos estudos relativos à as-sociação entre alexitimia e PHDA tanto em adultos como em crianças, e nenhum na população portuguesa.
MÉTODOS: A amostra acidental inclui 50 crianças previamente diagnosticadas com PHDA e sob tratamento e 51 crianças saudáveis sem PHDA, com idades compreendidas entre os 8 e os 17 anos. Com o intuito de avaliar a alexiti-mia foi aplicada a versão portuguesa do questionário de alexitimia para crianças.RESULTADOS: Comparando os dois grupos, não se verificaram diferenças significativas em nenhum dos três fatores da escala de alexitimia: dificuldade em identificar sentimentos, dificuldade em descrever sentimentos e pensamento orientado externamente, assim como na pontuação total da escala.
DISCUSSÃO: No nosso estudo, crianças com PHDA sob intervenção farmacológica e psicoterapêutica apresentaram níveis de alexitimia sobreponíveis à população controlo.
CONCLUSÃO: O nosso estudo pretende reforçar a importância da avaliação do processamento emocional na PHDA e a sua relação com as intervenções terapêuticas realizadas, abrindo portas a que outras investigações se dediquem a este tema.
Normal Appendix in the Elective Inguinal Hernia Repair: Case Report and Review of Literature

Published: June 2019

INTRODUCTION: The presence of the vermiform appendix in an inguinal hernial sac is known as an Amyand’s hernia. In the elective hernia repair, this represents a rare finding and the decision to perform appendectomy is always ambiguous. The literature seems to claim the idea that a normal appendix should be preserved unless the benefits of an appendectomy outweigh the risks of a future acute appendicitis. Our purpose was to analyse all published clinical cases of Amyand’s hernia indexed in MEDLINE and evaluate patient’s characteristics and the surgeons’ decisions regarding prophylactic appendectomy in these cases.METHODS: A bibliographic search of MEDLINE database using “Amyand’s Hernia” as keywords was done. Inclusion criteria included clinical cases in adults, where a normal, non-inflamed appendix was encountered during elective hernia repair. We also present the clinical case from our institution.
RESULTS: We identified 25 papers from which 41 clinical cases were extracted. In more than half the clinical cases the surgeons opted for a prophylactic appendectomy. This decision seemed to have no impact on the type of hernia repair (with/without mesh) or on the reported complications.
CONCLUSION: Amyand’s hernia is a rare finding, and even though prophylactic appendectomy is not recommended, most of the surgeons in the published clinical cases opted to do so. The absence of evidence-based information and the very low risk associated with appendectomy in this context may explain this option. The final decision therefore remains surgeon-dependent.

Published: June 2019

Electricity Market Act № 2019-VIII passed in 2017 by the Verkhovna Rada of Ukraine enacts in July 2019 and causes the transition of this segment of the economy to the free market principles. The implementation of this Act is perceived ambiguous. Many experts criticize this Act, which have numerous risks, especially pricing risks. In order to better understand the implications of the enactment of the adopted Act, a study was carried out on the methodology of the pricing mechanism in the retail segment of the electricity market based on the Demand Side Management (DSM) approach. In the study, one of the varieties of DSM models was used – a dynamic demand-supply model for describing the pricing mechanism and short-term forecast of retail prices. Test and comparative analysis were conducted. The last one based on possibilities of short-term forecasting of prices of DSM model with the well-known Holt-Winters method. For testing were set historical data on electricity prices in England and Wales, during the transition period from a model similar to the current model of the Ukrainian electricity market.
Predicting performance of a thermal shield of a spacecraft in a high-temperature gas flow
Authors: Gracheva Lyudmila Ivanovna 
Published: June 2019

A fundamental understanding of the mechanism of material interaction with a medium is based on correspondence between experimental studies and actual operating conditions of a given model or a structure. We estimated performance of thermal shield structures based on computations brought about considering physical properties of materials obtained under conditions simulating re-entry of a spacecraft into the atmosphere.A thermal shield is considered of a layered type shell, made of fiber glass with phenol-phormaldehide matrix. Both elastic and thermo-physical characteristics are varied depending on the temperature change.A thermal-stressed state of a cylindrical shield subjected to action of a high-temperature gas flow, is defined based on solving a 3D problem simultaneously using equations of theory of elasticity, thermal conductivity, and numerical analysis. Results are given as dependencies of stress distributions through the thermal coating, taking into account such parameters of atmosphere in re-entry as temperature, heating rate, pressure of a gaseous medium.
