Authors: Baharun Hasan , Adhimiy Syafiqiyah
Published: January 2019

Although there is no shârih (clear) propotion about the prohibition on going out of the house for a woman who has just been left dead by her husband (‘iddah wafat), but jurists of the four Islamic schools have agreed that women who are iddah wafat may not leave the house except in emergencies or in hajiyah (desperate need). But then they differed about the time and limit of the ban. This study examines the prohibition on going out of the house for a woman who has just been left dead by her husband according to the ulema of ‘four schools. This study uses descriptive analysis method, with analytical techniques in the form of inductive, deductive and comparative. Based on the results of the study, it can be concluded that women in ‘iddah wafat are allowed to leave the house if there is a need that requires them to leave the house in the morning in hajiyah (needs). While for the night, she may leave the house only at times and in dharâriyah (emergency). Limitation to leave the house for women ‘iddah wafat in hajiyah or dharûriyah conditions is solely for benefit and does not contradict to the principles of maslahah mursalah.Although there is no shârih (clear) propotion about the prohibitionon going out of the house for a woman who has just been left dead by her husband (‘iddahwafat), but jurists of the four Islamic schools have agreed that women who are iddah wafatmay not leave the house except in emergencies or in hajiyah (desperate need).

The Penology of Islamic Criminal Law: Reintroduction of Islamic Penology
Authors: Candra Marli
Published: January 2019

The justification for punishment is an interesting topic and undying debate among the scholars. Those who in favor of traditional approach would state that punishment is retributive in nature, whereas the opposite party would declare that punishment is for future benefits either particularly for offender or society in general. In this article, the researcher will elaborate the penological approach of punishment in Islamic criminal law. This study applies a comparative analysis based on the qualitative approach to compare the concept of punishment and its justification in the modern penology as well as in Islamic perspective. The study finds out that the justification for punishment in Islam, which is mainly contained in the hudûd and qishâsh offenses, does not deviate from what is understood by modern penology. Islamic law provides harsher punishment for serious offenses, but at the same time, it also prescribes ways on how to reduce such punishments.

Published: January 2019

La búsqueda de materiales alternativos que sustituyan parcialmente el cemento portland debido a la problemática ambiental que presenta este en su producción, nace la necesidad de investigar el empleo de mezclas ternarias (cemento Portland de uso general (OPC), residuo de mampostería (RM) y cal hidratada (CAL) para mejorar las propiedades de los concretos y disminuir su impacto ambiental. En este sentido, el presente trabajo estudió el efecto del empleo de RM proveniente de residuos de construcción y demolición (RCD) y CAL como sustitución parcial del cemento Portland (hasta un 20 % en peso) en concretos ternarios sobre las propiedades en estado fresco (asentamiento) y endurecido, como la resistencia a la compresión, tracción indirecta, absorción y porosidad y succión capilar. Por otra parte, se realizó la optimización de resistencia a la compresión a los 28 días de curado mediante un diseño de mezcla de vértices extremos. Los resultados mostraron que a mayor porcentaje de reemplazo de RM y menores de CAL presentaron mejores resistencias a la compresión que cuando se presentaba mayores porcentajes de cal hidratada.  La resistencia a la compresión aumentó en 25,1%  y 16,1% a los 28 y 60 días de curado con respecto a la mezcla patrón.

Рак молочной железы (РМЖ) является одной из наиболее распространенных форм солидных опухолей. Анализ особенностей патогенеза РМЖ на молекулярном уровне с применением современных методов генетического анализа и на разных стадиях заболевания позволяет получить новые данные для их дальнейшего применения в клинической практике. Молекулярное профилирование с применением технологий высокопроизводительного секвенирования все чаще применяют в качестве клинического теста при подборе таргетных препаратов для лечения пациентов с высокорезистентными к терапии опухолями при РМЖ. Целью работы было провести таргетное секвенирование генов BRCA1 и BRCA2 в составе панели онкогенов. Из 66 образцов ДНК пациентов с опухолями молочной железы, мутации BRCA1/2 обнаружены у 39 пацентов. Найдено 78 уникальных генетических вариантов, из них 30 мутаций в гене BRCA1 и 48 мутаций в гене BRCA2. Идентифицировано 33 мутации, оказывающие влияние на сайты посттрансляционной модификации белков (PMT-мутации).

Published: January 2019

Недавние достижения в области нанотехнологии, в том числе современные методы, позволяющие усовершенствовать технологии приготовления лекарственных средств, открыли новые горизонты в наномедицине, связанные с разработкой наноразмерных средств доставки лекарственных препаратов и целых комплексов. Последнее десятилетие большое внимание уделяется использованию нанопереносчиков ― усилия исследователей направлены не столько на разработку новых препаратов, сколько на поиск способов целевой доставки терапевтических и/или диагностических агентов. В работе рассмотрены трансдисциплинарный подход к получению наноматериалов, нанокомплексов, нановезикул и перспективы их применения в биологии и тераностике. Особое внимание уделено получению нанопузырьков, стимулчувствительных наночастиц и наносистем с привитым циклодекстрином при нестандартных условиях, таких как действие ультразвука и микроволнового излучения. Помимо использования в процессе приготовления наночастиц, ультразвук может также эффективно применяться для активации чувствительных нановезикул и наночастиц.

Травма спинного мозга (ТСМ) - это травматическое повреждение, не являющееся следствием заболевания. Мезенхимальные стволовые клетки (МСК) становятся одним из наиболее используемых типов стволовых клеток как в научных исследованиях, так и в клинических испытаниях. С учетом предыдущих работ, в которых использовали от 4 x 105 до 1 x 106 клеток, целью данного исследования было определить количество МСК, оптимальное для трансплантации при хронической ТСМ. Магнитные наночастицы (НЧ) использовали для доказательства точности проведенной трансплантации. С помощью магнитно-резонансной томографии (МРТ), диффузионно-тензорной визуализации (DTI), диффузионно-тензорной трактографии (DTT) и поведенческих тестов мы проверили влияние различного количества МСК на уменьшение пораженной полости и посттравматического свища, подавление формирования глиального рубца, усиление ремоделирования нейронных волокон, содействие регенерации и прорастанию аксонов, улучшение васкуляризации, повышение уровня экспрессии нейронных факторов и улучшение функционирования системы. Магнитные наночастицы были точно трансплантированы в посттравматический свищ (ПТС). МСК могут восстанавливать функцию после хронической ТСМ посредством стимуляции регенерации и прорастания аксонов, уменьшая образование ПТС. Таким образом, влияние МСК на ПТС и функциональное улучшение после хронической ТСМ зависит от количества клеток, и в диапазоне от 4 × 105 до 1 × 106 наилучшей дозой является 1 × 106.

Published: January 2019

Магнитные наночастицы (МНЧ) привлекают все больше внимания в качестве перспективного материала для разработки эффективных систем противоопухолевой терапии и диагностики. В данной работе исследовано влияние формы магнитного ядра наночастиц (НЧ) оксида железа на эффективность доставки доксорубицина в клетки линии 4T1. НЧ сферической и кубической формы синтезировали методом термического разложения, что позволило эффективно контролировать их форму и размер. После гидрофилизирования с помощью Pluronic F-127 в полученные средства доставки загружали доксорубицин (15,22% для сферических и 15,44% для кубических НЧ). Для незагруженного доксорубицина IC50 достигала 1 мкМ, в то время как для сферических и кубических НЧ с препаратом ― 6,4 мкМ и 5,5 мкМ соответственно. В протестированном диапазоне концентраций (1,77–227,2 мг/л) цитотоксичность у наночастиц без препарата не выявлена. Согласно данным динамики накопления доксорубицина, в клетках 4T1 активнее всего накапливается свободный доксорубицин и локализуется в клеточном ядре. Препарат, загруженный в НЧ, накапливается менее интенсивно и первоначально локализуется в везикулах вокруг ядра, обнаруживаясь в самом ядре лишь через 2 ч совместной инкубации. Доставка противоопухолевого препарата на кубических НЧ несколько более выражена на ранних сроках инкубации с клетками по сравнению со сферическими частицами, однако данная разница не существенна.
Reformulasi Hierarki Peraturan pada Pembentukan Peraturan Perundang-Undangan di Indonesia
Authors: Sagama Suwardi
Published: January 2019

This article discusses the hierarchy of regulation formation. The problem being discussed in this article is related to the regulations that are formed contrary to the rules above and therefore, they are canceled or revised. Although explicitly in the formation of regulations, it is mandatory to follow the regulation hierarchy. Hence, it causes financial problems because the regulations cannot be implemented. It is juridical normative based research. The result of this research suggests that it is necessary to reformulate the regulations hierarchy on the formation of state regulations. It also suggests that the hierarchy of the regulations formation has positive and negative values. It is positive because it can maintain orderliness in the formation of regulations, while negative values will occur in the formation of the regulations. Therefore, to strengthen the hierarchy of the formulation of laws and regulations, it is necessary to have specifically certified legal drafter to form the regulations. As in the principle of legal fiction, that person is considered to know the rule can be realized properly.

Effect of contrast medium injection rate on computed tomography-derived renal perfusion estimates obtained with the maximum slope method in healthy Beagles
Authors: Lee Sang-Kwon , Kim Cheolhyun , Yoon Sooa , Choi Jihye
Published: January 2019

OBJECTIVE To evaluate the effect of contrast medium injection rate on CT-derived renal perfusion estimates obtained with the maximum slope method in healthy small dogs.

ANIMALS 6 healthy sexually intact male purpose-bred Beagles.

PROCEDURES All dogs underwent CT perfusion analysis 3 times in a crossover design, receiving a different contrast medium injection rate (1.5, 3.0, and 4.5 mL/s) each time, with a 1-week interval between imaging sessions. All CT images were obtained at the level of the left renal hilus. The time to peak aortic enhancement (TPAE) and time to initial renal venous enhancement (TIRVE) were measured from time-attenuation curves. The renal CT perfusion estimates (blood flow and blood volume) were estimated by use of the maximum slope method, which assumes no venous outflow of contrast medium during CT perfusion analysis.

RESULTS The TPAE occurred at or before the TIRVE at all injection rates. Median values of estimated blood flow and blood volume did not differ significantly among injection rates.

CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that the assumption of no venous outflow of contrast medium during renal CT perfusion analysis with the maximum slope method was satisfied for all 3 contrast medium injection rates in the evaluated dogs. A low injection rate may be more practical than higher injection rates that require large catheters for CT perfusion analysis in small dogs such as Beagles.

Authors: Yang Wenbin , Jiang Sen , Lin Jianbang , Li Yangkang
Published: January 2019

Background

Peripheral T-cell lymphoma (PTCL) is an uncommon disease with poor clinical outcomes. Radiological reports on the survival of patients with PTCL are scarce. The purpose of this study is to investigate the prognostic value of CT findings to predict clinical outcomes in fifty-one patients with histologically proven PTCL.

Patients and methods

The clinical data and CT images of all patients were retrospectively reviewed. CT features including number of involvement sites, lesion size, shape, margin, density, peritumoral invasion, intratumoral necrosis, lymph node involvement, and degree of contrast enhancement were evaluated. Univariate and multiple logistic regression analysis were used to determine the association between the clinical outcome and radiologic factors.

Results

Multiple site involvement, an ill-defined margin with peritumoral invasion, inhomogeneous density, and intratumoral necrosis were found to be associated with poor outcomes in univariate analysis (P < 0.05). An ill-defined margin with peritumoral invasion, was identified as an independent risk sign by further multivariate logistic regression analysis (P < 0.05). The area under the ROC curve of this CT feature was 0.745 (P < 0.05).

Conclusions

An ill-defined margin with peritumoral invasion was a valuable prognostic factor to predict the worse clinical outcomes in patients with PTCL.
Estimativa da resistência não drenada através da energia de cravação do SPT
Authors: Rodríguez Camilo , Schnaid Fernando , Odebrecht Edgar
Published: January 2019

O presente trabalho tem por objetivo a proposição de um método para a estimativa da resistência ao cisalhamento não drenada (Su) através de uma metodologia desenvolvida com base nos conceitos de propagação de ondas transmitidas no ensaio SPT. As estimativas são baseadas em um banco de dados de ensaios realizados em depósitos argilosos, que subsidiam a análise e formulação da proposta. O método combina o cálculo da energia dos ensaios SPT à capacidade de carga estática por equilíbrio limite para uma estaca isolada. A estimativa de Su é obtida através de formulação para determinação do coeficiente de adesão α como função direta do NSPT, desenvolvida a partir de um ajuste estatístico. O método proposto resulta em estimativas na faixa de grandeza de valores observados em campo, com um coeficiente de correlação médio (r2) de 0,65%, que reflete a dispersão inerente de resultados de ensaios SPT.

Critérios de engenharia para classificação de materiais de escavação em valas
Authors: Neto Silvrano , Filho Francisco , Silva Adriano
Published: January 2019

No Brasil, em obras de abastecimento de água e esgoto, a classificação dos materiais das escavações realizadas se dá em função da dificuldade que estes oferecem ao desmonte, como materiais de 1ª, 2ª e 3ª categorias, não havendo critérios de engenharia bem definidos para tal classificação. Este trabalho tem por objetivo apresentar uma proposta para classificação de materiais de escavação com base em critérios de engenharia definidos a partir de resultados de sondagens de simples reconhecimento (sondagens a trado, SPT e rotativa). Para aplicação de tal proposta, foi considerado um estudo de caso, que consistiu na classificação de materiais no Município de Coreaú, Estado do Ceará, na qual havia um conflito referente à quantificação dos materiais obtidos na escavação. Os resultados mostraram que os critérios propostos permitiram a classificação satisfatória dos materiais em função de ensaios geotécnicos correntes.

Published: January 2019

Barreiras verticais de contenção de contaminantes constituem atualmente uma solução rápida e eficaz na solução de problemas geotécnicos ambientais de contenção de contaminações subsuperficiais. Com o objetivo de estudar o comportamento de materiais de preenchimento para estas barreiras, ensaios triaxiais convencionais adensados não drenados (CIU) e ensaios de condutividade hidráulica foram realizados em misturas de solo-bentonita (SB) e solo-cimento-bentonita (SCB). Foram analisados diferentes fatores água cimento, teores de umidade e tensões confinantes, assim como três valores distintos de teor de bentonita nas amostras de SCB e dois teores de bentonita para as amostras de SB. A análise global dos resultados permitiu identificar as alterações provocadas no comportamento mecânico e condutividade hidráulica, mediante a variação dos parâmetros citados. Os ensaios CIU indicaram que, para um mesmo teor de bentonita, a diminuição do fator água-cimento ocasionou um aumento nos parâmetros de resistência ao cisalhamento do material. Para um fator a/c=6, o aumento do teor de bentonita também ocasionou um aumento nos parâmetros de resistência do material. A condutividade hidráulica das misturas de SB apresentou valores inferiores em relação às misturas de SCB.

Published: January 2019

A engenharia geotécnica é um dos primeiros domínios técnico-científicos a intervir em qualquer projeto de infraestruturas ou de desenvolvimento urbano, sendo, muitas vezes, o mais importante. No decurso dos tempos muitas inovações metodológicas, analíticas, numéricas e tecnológicas foram sendo descobertas e utilizadas nas investigações de campo e de laboratório e nas áreas da análise, do projeto e da construção de estruturas geotécnicas. Os campos em que a geotecnia tem forte intervenção e onde essas inovações foram sendo introduzidas são muito vastos e espraiam-se por escalas muito diversas. A globalização mundial, a utilização não sustentável dos recursos, as alterações ambientais causadas por razões antrópicas, o aumento dos desastres naturais e a carência de infraestruturas para dar resposta às necessidades das populações criam um quadro que condiciona decisivamente a evolução da engenharia geotécnica. Neste conjunto de quatro artigos perspetiva-se o futuro da geotecnia: parte-se de uma caracterização, feita no 1º artigo, das diversas condicionantes, tanto sociais, económicas e ambientais, como geotécnicas, e das necessidades das sociedades humanas, sumariadas no 2º artigo, e apontam-se vias de desenvolvimento futuro consideradas como das mais relevantes.

Published: January 2019

Muzički žanrovi su konvencionalne kategorije koje se koriste za opisivanje muzike. Danas se najčešće koriste za klasifikaciju rastućeg broja muzičkih numera, koja bi dalje trebalo da omogući precizniju preporuku i jednostavniju pretragu muzike. U radu je analizirano  nekoliko metoda i strategija za automatsku klasifikaciju muzike uključujući  konvolucione neuronske mreže (Convolutional neural network – CNN), rekurente neuronske mreže (Reccurent neural network – RNN), mašine potpornih vektora (Support vecotor machines – SVM), random forrest (RF), AdaBoost kao i One vs. Rest (OVR) i klasifikaciju glasanjem. Muzičke numere klasifikovane su na osnovu mel-frequency cepstrum coefficients (MFCC) predstave audio zapisa, a za potrebe CNN-a korišćen je spektrogram. Ostvareni rezultati (~60%) se mogu porediti sa tačnošću (~70%) sa kojom su ljudi u stanju da ispravno procene muzički žanr kao i sa rezultatima ostvarenim u radovima koji su se bavili sličnom temom na istom skupu podataka. Obzirom da preciznost ostvarena u radu nije daleko od procene ljudi, metode bi mogle naći primenu u automatskoj klasifikaciji muzike za potrebe radio stanica ili web sajtova koji se bave distribuiranjem i preporukom muzičkih numera.

Published: January 2019

Problem kojim se bavi ovaj rad jeste predikcija indeksa korisnosti igrača u euroligi. Ovaj rad nastoji da iskoristi veliku količinu podataka, koji se nalaze na oficijalnom sajtu evrolige, obradi ih i pripremi za upotrebu algoritama mašinskog učenja. Algoritmi koji su razmatrani u ovom radu su Naive Bayes, SVM (Support Vector Machine) i KNN (K nearest neighbours). Za svaki algoritam izvšena je optimizacija parametara koji najviše utiču na samu klasifikaciju. Osim navedenih algoritama mašinskog učenja, razmatrana su još dva jednostvna algoritma za predikciju indeksa korisnosti koje je implementirao autor. Najbolju tačnost od 92% postigao je algoritam SVM, dok su algoritmi Naive Bayes i KNN imali manju tačnost od 87%, odnosno 72%. Namenski razvijeni algoritmi imali su značajnije manju tačnost od algoritama mašinskog učenja.

Published: January 2019

ABSTRAKDeteksi sinyal banyak diimplementasikan dalam sistem pengolahan sinyal yang sangat kompleks. Sebagai contoh digunakan pada sub sistem pengolahan sinyal radar pengintai yang berfungsi untuk deteksi dan pelacakan target. Salah satu implementasi terbaru dari deteksi sinyal adalah untuk fungsi spectrum sensing pada Cognitive Radio. Deteksi sinyal dapat didefinisikan sebagai binary hypothesis testing, yaitu memutuskan satu dari dua keadaan: hanya derau atau tidak ada sinyal (null hypothesis), dan ada sinyal (alternative hypothesis). Teori deteksi sinyal merupakan bidang yang cukup luas, sehingga paper ini fokus pada pendekatan parametrik dengan Teorema Neyman-Pearson. Kedua hypothesis dimodelkan dengan variabel acak dengan distribusi rapat kemungkinan yang sama tetapi mempunyai parameter yang berbeda. Ditunjukkan penurunan test statistic untuk dua skenario, yaitu distribusi dengan diketahui sebagian dan diketahui penuh. Bagian simulasi menunjukkan kinerja detektor sinyal secara analitis mempunyai hasil yang serupa dengan simulasi Monte Carlo.Kata kunci: deteksi sinyal, Neyman-Pearson, hypothesis testing, spectrum sensing, radar. ABSTRACTSignal detection has been used in many sophisticated signal processing systems, such as for signal processing in surveillance radar which is to detect and to track a radar target. Recently, signal detection is widely used for spectrum sensing in Cognitive Radio. Signal detection is a binary hypothesis testing problem which is to choose one out of two conditions, i.e., noise only or signal absence (null hypothesis), and signal presence (alternative hypothesis). Since signal detection theory is a wide area, this paper only focuses on parametric approach using Neyman-Pearson theorem. The two hypotheses are modeled by random variables having the same distribution but different parameters. The derivations of test statistics (detectors) are shown for two scenarios, i.e., partially known and perfectly known distributions. Analytical results and Monte Carlo simulations of the derived detectors show similar performances.Keywords: signal detection, Neyman-Pearson, hypothesis testing, spectrum sensing, radar.

ABSTRAKSimulator tekanan darah biasa digunakan sebagai nilai referensi dalam mengevaluasi tensimeter otomatis (NIBP monitor). Penelitian sebelumnya menunjukkan bahwa simulator tekanan darah dapat dibuat dengan menggunakan micro air pump berbasis motor dc sebagai aktuator. Namun, hasil simulasi yang dihasilkan berbeda untuk setiap merek tensimeter. Hasil analisa menunjukkan bahwa laju inflasi dan deflasi yang berbeda mempengaruhi karakteristik simulasi. Studi ini bertujuan untuk mengembangkan firmware simulator baru berdasarkan nilai pulse width modulation (PWM) dan gradien inflasi-deflasi untuk meminimalkan pengaruh tersebut, sehingga simulator dapat memberikan hasil yang sama untuk berbagai jenis dan merek NIBP monitor. Validasi dengan simulator referensi dan evaluasi dalam kondisi statis dan dinamis menunjukkan simulator yang dikembangkan cukup andal untuk melakukan pemeriksaan awal, termasuk evaluasi pengulangan hasil tensimeter otomatis.Kata kunci: NIBP monitor, PWM, NIBP simulator, gelombang osilasi, lajuinflasi, laju deflasi  ABSTRACTBlood pressure simulators are commonly used as reference values in evaluating NIBP (noninvasive blood pressure) monitors. Prior research shows that an NIBP simulator can be made using dc motor based micro air pump as the actuator. However, the simulator yield different results for different brands of NIBP monitor. The analysis result showed that inflation/deflation rates do affect the simulation’s characteristic. This research aims to develop a new simulator firmware based on pulse width modulation (PWM) values and rising-falling slope to minimize the corresponding effect so that the developed simulator could generate the same result for various types and brands of NIBP monitor. Validation using a reference simulator and evaluation in static and dynamic conditions showed that the developed simulator is reliable enough to do a quick pre-checks, including assessing the repeatability of NIBP monitors.Keywords: NIBP Monitor, PWM, NIBP Simulator, Oscillometric Waveform, Inflation Rate, Deflation Rate
Решение задачи об электронно-колебательно-вращательных уровнях энергии многоатомной молекулы произвольного строения в обобщенных координатах
Authors: Грибов Л.А.
Published: January 2019

Задачи в классической механике при анализе движения в объектах со многими степенями свободы ставятся и решаются в системе не декартовых, а обобщенных координат. Показано, что аналогичный подход применим и в квантовой механике. И в том, и в другом случае для постановки задачи требуется ввести в подходящих координатах потенциальную функцию и найти матрицу кинематических коэффициентов, входящую в классическое выражение для кинетической энергии в импульсном представлении. Последовательно обсуждается возможность такой же постановки задачи об уровнях энергии многоатомной молекулы и приводятся примеры ее решения при использовании обобщенных координат.

Показано, что увеличение длины алифатической цепочки в аминной части лигандных систем блокирует образование биядерных металл-хелатных структур. В то же время моноядерные бис-хелат­ные комплексы, а также моноаддукты с координированной молекулой растворителя и тридентатно связанным азометиновым соединением формируются вне зависимости от количества метиленовых звеньев.

Authors: Paul A.K. , Kanagaraj R.
Published: January 2019

A crystalline mixed-metal sulfate compound NaPr(SO4)2(H2O) is synthesized under hydrothermal conditions and thoroughly characterized. Sodium bisulfite (NaHSO3) and piperazine are used with praseodymium acetate to obtain this sulfate-based structure. The single crystal structural analysis shows that the compound has the NaCe(SO4)2×H2O structure type and crystallizes in the trigonal space group P3221 (No. 154) with a = 6.9872(2) Å, c = 12.8935(8) Å, and V = 545.14(4) Å3. The compound has three-dimensional connectivity formed by the sulfate units with Pr and Na centers. Tricapped trigonal prismatic PrO9 units and square-antiprismatic NaO8 units link to the SO4 tetrahedron for building the three-dimensional structure. The compound is also characterized by PXRD, TGA, and FT—IR spectroscopy. The present study illustrates the usefulness of the bisulfite anion and secondary amine for the chiral structure building.
