Prospek Hukum Islam dalam Sistem Hukum Indonesia
Authors: Saifuddin Saifuddin
Published: January 2019

Although the majority of Indonesian citizens are Muslims, Islamic law cannot automatically apply in this country. This is because Indonesia is not a religious state and does not make religion as the state's ideology. This article analyzes the prospects of tranformation of Islamic law into the national legal system. The aim is to find a format that is in accordance with the character of the Indonesian state and does not deviate from state idiology of Pancasila . This study concludes that there are only a few ways to enforce Islamic law in Indonesia without changing the existing state order. First: through a constitution amendment. Islamic law can be transformed into positive law insofar as it is accepted by the legislative body through democratic ways. Second: through the transformation of legal material. This method is carried out by changing the material law based on secular values into a legal product based on Islamic values. Third: through regional autonomy. such as in Aceh, Banten, Madura, and Gorontalo.
Alternative Dispute Resolution Model in the AJB Bumiputera Life Insurance Company of Purwokerto in Shari'ah Perspectives
Authors: Triana Nita
Published: January 2019

Resolution of disputes by way of litigation always takes a long time, expensive dan results in a win and lose solution. Therefore resolution outside the court( non-litigation) is an alternative choice. This study analyses the resolution of insurance disputes using several methods or models outside the Court. This research is non-doctrinal legal research, with a socio-legal approach. It analyses a settlement model used by of Life Insurance AJB Bumiputera Purwokerto in the event of default of the insured/customer premium and the customer’s insurance claim against the company. The settlement involves several stages, first, by means of consultation and negotiation, second by means of mediation involving OJK (Financial Services Authority) as a neutral mediator, and the last, by means of conciliation and arbitration. In the perspective of Islamic law, this solution model is similar to the concept of sulh, a type of disputes resolution in which the conflicting parties drive to settle their dispute peacefully.
Islam and the Provisions of War
Authors: Iwansyah Henry
Published: January 2019

This article compares the provisions of war in Islam with the provisions contained in International Humanitarian Law (The four Geneva Conventions of 1949 and their Additional Protocols). The aim is not to judge Islamic according to or vice versa, but rather, to discover similarities and differences between the two regulations in governing the conduct of war. The study uses a comparative approach, exploring the Islamic values of ethics and rules of conduct of war and then comparing them with similar provisions of international humanitarian law. This article also analyzes the possibility of synthesizing the two legal system. Having reviewed the topic thoroughly, this study concludes that, in principle, there is no difference between Islamic law and international humanitarian law in regulating procedures and ethics of warfare. Both of the legal system are equallyconcern to regulate the behaviour of warriors by limiting the use of force and minimizing the impact of the battles to civilians

Радионуклидная терапия (РНТ) является эффективным методом лечения множественных метастазов злокачественных опухолей. Расширение номенклатуры злокачественных новообразований, для которых возможно применение РНТ происходит за счет создания новых туморотропных радиофармацевтических препаратов (РФП). Перспективно создание РФП на основе универсальной транспортной платформы, которая может быть модифицирована различными терапевтическими и диагностическими радионуклидами, а также векторными молекулами для достижения требуемой специфичности к опухолям и терапевтической эффективности. Целью данной работы было оценить в качестве такой транспортной платформы конструкцию на основе оригинального дендримера. Исследование на мышах показало его низкую токсичность (ЛД50 достигало 779 ± 111 мг/кг). Туморотропность и терапевтическую эффективность дендримера проводили для наноконструкции из дендримера, RGD-пептида и радионуклида 188Re (188Re-НК). В качестве опухолевой модели использовали мышиную карциному легкого Льюиса LLC1. Данные биораспределения предложенной наноконструкции показали ее эффективное накопление в опухоли с коэффициентом дифференциального накопления более 1 по отношению к основным органам и тканям и временем удержания в опухоли не менее 6 ч. Введение 188Re-НК в дозе 185 МБк/кг мышам с подкожно трансплантированной опухолью статистически достоверно (p < 0,05) способствовало торможению роста опухоли к 7-м суткам после введения до Т/С=5%, сохраняющемуся в течение 6 суток. Проведенные исследования показали перспективность исследованного дендримера как транспортной платформы для РНТ.
Problematika Yuridis Wakaf Hak Kekayaan Intelektual di Indonesia
Authors: Niswah Eva Mir'atun
Published: January 2019

Intellectual Property Rights (IPR) is one of movable objects that can be represented according to waqf regulation (Undang-Undang No. 41 Tahun 2004 Tentang Wakaf). The previous regulations did not mention IPR as waqf object. IPR becomes waqf object because there is a shift of  paradigm on productive waqf. However, the waqf regulation (Undang-Undang No. 41 Tahun 2004 Tentang Wakaf) has many juridical problems. For example, there is no specific explanation about IPR waqf as well as money waqf. Besides, the IPR practice is very rare due to unclear forms of IPR waqf. Juridical problems on IPR waqf are related to legal substance, legal structure and legal culture. On legal substance, there is no clear explanation and mechanism of IPR waqf. On legal structure, there is no clear explanations about who can be the wakif or nazir on IPR waqf. On legal culture, many people are still unfamiliar with intangible waqf object (the conventional waqf object is land). Therefore, the acceptance of an intangible object such as IPR as a waqf object is very low.

Authors: Nainggolan Ivani Juni , Handoyo Sofik
Published: January 2019

This study aims to examine the effect of implementing Corporate Social Responsibility (CSR) on the company's financial performance, with the industry type as a moderating variable. CSR disclosure was measured using CSR disclosure under ISO 26000. Return on Asset is a proxy to measure the company’s financial performance. The type of industry was divided into a high profile and low-profile company. The research subjects are the leading sector companies (raw material producing industries) and the second sector (manufacturing industries) which consist of various sectors namely agriculture, mining, basic and chemical industries, various industries, and consumer goods which are listed on the Indonesia Stock Exchange in 2012-2013. Partially, the results showed that the disclosure of CSR implementation and industry type positively and significantly affected the company's financial performance, and the type of industry succeeded in becoming a moderating variable that influenced the relationship between CSR disclosure and the company's financial performance. Simultaneously, the results of the study also show that there is a significant effect of the level of disclosure of Corporate Social Responsibility (CSR) on financial performance with industry type as a moderating variable.

Authors: Hopster Klaus , Bertone Cristina , Driessen Bernd
Published: January 2019

OBJECTIVE To evaluate the effects of 4 gas compositions at various volumes (simulated tidal volumes [VTs]) on accuracy of measurements obtained with 2 types of flow sensors and accuracy of gas volume delivery by a piston-driven ventilator.

SAMPLE 4 gas mixtures (medical air [21% O2:79% N2], > 95% O2, O2-enriched air [30% O2:70% N2], and heliox [30% O2:70% He]).

PROCEDURES For each gas mixture, reference VTs of 1 to 8 L were delivered into an anesthetic breathing circuit via calibration syringe; measurements recorded by a Pitot tube-based flow sensor (PTFS) connected to a multiparameter host anesthesia monitor and by a thermal mass flow and volume meter (TMFVM) were compared with the reference values. Following leak and compliance testing, the ventilator was preset to deliver each gas at VTs of 1 to 8 L into the calibration syringe. Effects of gas volume and composition on accuracy of VT measurement and delivery were assessed by ANOVA. Agreements between delivered and flow sensor-measured VT and preset versus ventilator-delivered VT were determined by Bland-Altman analysis.

RESULTS Flow sensor measurements were accurate and not influenced by gas composition. Mean measurement error ranges for the PTFS and TMFVM were −4.99% to 4.21% and −4.50% to 0.17%, respectively. There were no significant differences between ventilator-delivered and reference VTs regardless of gas volume or composition. Bland-Altman analysis yielded biases of −0.046 L, −0.007 L, −0.002 L, and 0.031 L for medical air, > 95% O2, O2-enriched air, and heliox, respectively.

CONCLUSIONS AND CLINICAL RELEVANCE The PTFS and the TMFVM measured VTs and the piston-driven ventilator delivered VTs with error rates of < 5% for all gas compositions and volumes tested.

OBJECTIVE To describe perfusion and diffusion characteristics of the liver, spleen, and kidneys of healthy adult male cats as determined by morphological, perfusion-weighted, and diffusion-weighted MRI.

ANIMALS 12 healthy adult male cats.

PROCEDURES Each cat was anesthetized. Morphological, perfusion-weighted, and diffusion-weighted MRI of the cranial aspect of the abdomen was performed. A region of interest (ROI) was established on MRI images for each of the following structures: liver, spleen, cortex and medulla of both kidneys, and skeletal muscle. Signal intensity was determined, and a time-intensity curve was generated for each ROI. The apparent diffusion coefficient (ADC) was calculated for the hepatic and splenic parenchyma and kidneys on diffusion-weighted MRI images. The normalized ADC for the liver was calculated as the ratio of the ADC for the hepatic parenchyma to the ADC for the splenic parenchyma.

RESULTS Perfusion-weighted MRI variables differed among the 5 ROIs. Median ADC of the hepatic parenchyma was 1.38 × 10−3 mm2/s, and mean ± SD normalized ADC for the liver was 1.86 ± 0.18. Median ADC of the renal cortex and renal medulla was 1.65 × 10−3 mm2/s and 1.93 × 10−3 mm2/s, respectively.

CONCLUSIONS AND CLINICAL RELEVANCE Results provided preliminary baseline information about the diffusion and perfusion characteristics of structures in the cranial aspect of the abdomen of healthy adult male cats. Additional studies of cats of different sex and age groups as well as with and without cranial abdominal pathological conditions are necessary to validate and refine these findings.

Published: January 2019

Background

The aim of the study was to evaluate diagnostic performance of functional parameters derived by conventional mono-exponential approach of diffusion weighted imaging (DWI) and by diffusion kurtosis imaging (DKI) in the assessment of pancreatic tumours treated with electrochemotherapy (ECT).

Patients and methods

Twenty-one consecutive patients with locally advanced pancreatic adenocarcinoma subjected to ECT were enrolled in a clinical approved trial. Among twenty-one enrolled patients, 13/21 (61.9%) patients were subjected to MRI before and after ECT. DWI was performed with a 1.5 T scanner; a free breathing axial single shot echo planar DWI pulse sequence parameters were acquired using seven b value = 0, 50, 100, 150, 400, 800, 1000 s/mm2. Apparent diffusion coefficient by conventional mono-exponential approach and mean of diffusion coefficient (MD) and mean of diffusional kurtosis (MK) by DKI approach were derived from DWI. Receiver operating characteristic (ROC) analysis was performed and sensitivity, specificity, positive and negative predictive value were calculated.

Results

Among investigated diffusion parameters, only the MD derived by DKI showed a significant variation of values between pre and post treatment (p = 0.02 at Wilcoxon test) and a significant statistically difference for percentage change between responders and not responders (p = 0.01 at Kruskal Wallis test). MD had a good diagnostic performance with a sensitivity of 80%, a specificity of 100% and area under ROC of 0.933.

Conclusions

MD derived by DKI allows identifying responders and not responders patients subject to ECT treatment. MD had higher diagnostic performance to assess ECT response compared to conventional DWI derived parameters.
Consideração de detalhes executivos no projeto de taludes com solo grampeado
Authors: Gerscovich Denise , Sayão Alberto , Lima André , Rosa Cauê
Published: January 2019

A técnica de estabilização com solo grampeado, ou pregado, consiste na instalação de elementos de reforço semirrígidos na massa de solo. O processo construtivo é realizado em etapas sucessivas de escavação, abertura de um furo para execução do grampo normal à face com a instalação da barra de aço, envolvida com calda de cimento, por gravidade ou por injeção em uma ou mais vezes. Ao final a face da escavação é protegida com tela metálica e revestida com concreto projetado. Os grampos são mobilizados em decorrência do desconfinamento induzido pela escavação progressiva do solo. Junto à parede, o grampo poderá ter deslocamento restringido ou livre, dependendo do tipo de acabamento. O projeto baseia-se, em geral, em análises de equilíbrio limite, sendo necessário o conhecimento da resistência ao cisalhamento (qs) mobilizada no contato solo-grampo. O valor de qs adotado no projeto deve ser confirmado em ensaios de arrancamento durante a obra. Há sugestões, na literatura, de correlações empíricas para estimar qs em função do índice de resistência à penetração (NSPT). Este trabalho tem como objetivo ressaltar influência dos aspetos construtivos na estimativa de parâmetros de projeto e no comportamento da obra, em termos de deslocamento e tensões transmitidas aos grampos. É apresentada uma nova proposta de correlação entre os valores de qs e NSPT, para solos típicos brasileiros. Adicionalmente, recomenda-se cautela ao se fazer uma previsão numérica do comportamento tensão-deformação de taludes grampeados, de modo a incorporar os aspetos executivos.

Authors: Sousa Nelci , Soares Anderson
Published: January 2019

A rocha calcária é abundante no subsolo da região de João Pessoa, capital do Estado da Paraíba, favorecendo o uso como agregado, devido sua extração econômica e baixos custos de transporte. Entretanto, é uma rocha sedimentar, constituída de material solúvel quando exposto à presença de água. Este trabalho propõe caracterizar a rocha calcária daquela região, verificando a sua aplicação como agregado de concreto. Foram executados ensaios de densidade real dos grãos; de massa específica aparente seca; de absorção de água; testes de abrasão, de resistência à compressão simples e análise física, em situação seca e saturada; de microscopia eletrônica; de difração de raios-X; e ensaios de campo. Os resultados indicaram que ela é composta de carbonato de cálcio (CaCO3), com alto índice de absorção de água e baixa resistência à abrasão e à compressão simples, concluindo que o seu uso deve ser restrito a determinados tipos de construções.
Desenvolvimento da geotecnia. Necessidades infraestruturais e perspetivas genéricas
Authors: Silva Cardoso António
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 e apontam-se vias de desenvolvimento futuro que ao autor parecem das mais relevantes.
Aplicação de uma metodologia multicritério construtivista à avaliação da vulnerabilidade de barragens e regiões a jusante
Authors: Baima Sandra , Campos José , Silva Adriano
Published: January 2019

Este artigo apresenta um modelo de classificação da vulnerabilidade de barragens, baseado em uma Metodologia Multicritério de Apoio à Decisão – MCDA (Multicriteria Decision Aid) que se caracteriza por adotar uma abordagem construtivista. A ferramenta escolhida para implementar esta MCDA-C foi o MACBETH por se tratar de uma metodologia que torna possível explicitar a forma como são atribuídos os pesos empregados neste tipo de classificação, através de um modelo formal e teoricamente robusto. A construção do modelo seguiu as fases da metodologia MACBETH e teve como base o sistema de classificação por categoria de risco e de dano potencial associado, estabelecido pela Resolução CNRH nº 143. Ao final aplica-se o modelo desenvolvido, avaliando um conjunto de 15 barragens de terra, e propõe-se um Índice de Vulnerabilidade de Barragens (IVB) e um Índice de Vulnerabilidade a Jusante (IVJB), a partir do suporte informático M-MACBETH.
Desenvolvimento de uma célula para realização de ensaios triaxiais em solos compactados rígidos
Authors: Oliveira Alex , Filho Francisco , Pessoa José
Published: January 2019

Este trabalho apresenta uma célula triaxial desenvolvida para realizar ensaios em solos compac ta dos de alta rigidez. O equipamento foi desenvolvido para facilitar a execução do ensaio triaxial, possibilitando a determinação dos parâmetros de resistência ao cisalhamento do solo, em laboratórios que não disponham de grande infraestrutura ou mesmo no campo. Na célula apresentada, a pressão confinante é aplicada por ar comprimido, não há um sistema de aplicação de contrapressão e não é possível o monitoramento das poro-pressões desenvolvidas. O ensaio é executado com baixa velocidade, livre drenagem para a água e o ar e a fase de ruptura pode ser realizada numa prensa de CBR (com deformações controladas) ou numa prensa de adensamento adaptada (com tensões controladas). Para a verificação do equipamento foram realizados ensaios, nas mesmas condições, utilizando a célula desenvolvida e a convencional. Os resultados obtidos indicaram que a nova célula pode ser utilizada para solos rígidos, como os utilizados normalmente em pequenas barragens de terra.

Published: January 2019

O objetivo desse trabalho foi avaliar a erodibilidade de um Cambissolo existente na sub-bacia do Córrego do Yung, localizada em Juiz de Fora, mesorregião da Zona da Mata Mineira. Analisou-se o comportamento dos horizontes pedológicos B e C, e, a partir de ensaios geotécnicos, de caracterização mineralógica e de caracterização física dos materiais, foram estabelecidas correlações qualitativas com a sua erodibilidade. Assim, determinou-se a granulometria, os limites de liquidez e plasticidade, mineralogia (difração de raios-X), a erodibilidade (Inderbitzen) e a resistência ao cisalhamento direto. O solo foi classificado como Cambissolo Háplico Tb Distrófico latossólico. O ensaio de Inderbitzen apresentou maior perda de solo acumulado no horizonte C, em vista do menor teor de argila e ausência de estrutura, que condicionam grãos mais soltos. Também foi verificada menor resistência ao cisalhamento na condição inundada desse horizonte. Concluindo, na sub-bacia do Córrego do Yung as áreas com maior potencial de erosão são aquelas em que se expõe o horizonte C.
Efeito do zinco e cobre na desagregação de seis solos do Distrito Federal, Brasil
Authors: Souza Newton , Gimenez Boscov Maria , Gurjão Cláudia
Published: January 2019

O efeito desagregador de lixiviados gerados em aterros de resíduos sobre as partículas sólidas de liners de solo compactado, com consequente alteração das propriedades mecânicas e hidráulicas da barreira mineral, é ainda mais preocupante no caso de solos tropicais lateríticos, nos quais os argilo-minerais estão aglomerados em concreções cimentadas por óxidos e hidróxidos de ferro e alumínio. A agregação é geralmente estudada com base no teor de argila do solo obtido por ensaios com e sem agentes desagregadores, químicos e/ou mecânicos. Este trabalho apresenta o comportamento à desagregação química por hexametafosfato de sódio e soluções monoespécies de zinco e cobre (50 a 800 mg/L) e à desagregação física por ultrassom de seis solos do Distrito Federal, Brasil, representativos de seis classes da Classificação MCT (Miniatura, Compactação, Tropical) de solos tropicais. O zinco e o cobre causaram desagregação dos solos estudados, com exceção dos solos NA e NA´, que pouco são afetados por possuírem pequena quantidade de argila. O efeito da desagregação provocada por esses metais é mais notável no solo NS´. O cobre causa maior desagregação quando comparado com o zinco. Por outro lado, os dois metais promoveram um aumento da resistência à ação desagregadora do ultrassom nos solos estudados, à exceção do solo NS´. Esse aumento foi maior para os solos contaminados com zinco. Assim se pode dizer que soluções de cobre podem causar maior dano que as de zinco a um liner de solo compactado.

Published: January 2019

Our main objective is in antagonizing the performance of two approaches: the Newton-Raphson (N-R) algorithm and maxLik function in the statistical software R to obtain optimization roots of estimating functions. We present the approach of algorithms, examples and discussing about two approaches in detail. Besides, we prove that the N-R algorithm can perform if our data set contain missing values, while maxLik function cannot execute in this situation. In addition, we also compare the results, as well as, the time to run code to output the result of two approaches through an example is introduced in [1].This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Published: January 2019

ABSTRAKSimulator penggunaan energi listrik sangat membantu dalam perencanaan pasokan listrik secara terus menerus atau perlu pemadaman bila terjadi gangguan. Agar kinerja pembangkit dapat kembali normal, bertahap, dan terencana akibat mengalami gangguan, maka digunakan metoda Load Shedding. Sistem otomasi dibutuhkan untuk merealisasikan metoda Load Shedding, dan melalui simulator dapat mengurangi resiko terhadap kerusakan bila langsung diimplementasikan. PLC digunakan untuk memprediksi beban saat load shedding, sedangkan SCADA digunakan untuk menampilkan prioritas dan status beban. Load shedding 1 adalah tindakan pelepasan beban bila pada salah satu genset mengalami gangguan, sedangkan Load shedding 2 bila pada kedua genset mengalami gangguan. Simulasi sistem load shedding 1 dan 2 berhasil dilakukan pelepasan beban secara otomatis. Setelah pelepasan beban, kapasitas beban yang ditanggung genset sesuai dengan prediksi dari PLC. Terdapat perbedaan hasil antara daya yang diprediksi secara perhitungan dan daya terukur, kemungkinan disebabkan beban masih belum steady saat data diambil.Kata kunci: Otomasi, Simulator, Sistem Load shedding, SCADA, PLC ABSTRACTSimulator of the use of electrical energy is very helpful in planning electricity supply continuously or needs to be suppressed if a disturbance occurs. In order for the generator performance to return to normal, gradual, and planned due to interference, the Load Shedding method is used. Automation systems are needed to realize the Load Shedding method, and through simulators can reduce the risk of damage if implemented immediately. PLC was used to predict load during load shedding, while SCADA was used to display priority and load status. Load shedding 1 was a load release action if one of the generator sets was disrupted, while Load shedding 2 if in both gensets were disrupted. Load system simulation of shedding 1 and 2 was successfully released by load automatically. After the load was released, the load capacity borne by the generator was in accordance with the predictions of the PLC., the load capacity borne by the generator was in accordance with the predictions of the PLC. There was a difference in results between the predicted power and measured power, possibly because the load was stillnot steady when the data was taken.

Published: January 2019

The aim of this paper is to set some scenarios for small and medium enterprises (SMEs) from a critical analysis of the provisions in the North American Free Trade Agreement (NAFTA) renegotiation, its challenges and opportunities. The critical analysis departs from the questionable position of the withdrawal from NAFTA and their consequences for SMEs of not giving continuity through a process of renegotiation among the three partners. The method used is the critical analysis based mainly in some sources of information, analysis of results of NAFTA, and the strategic examination of its challenges and opportunities for SMEs. Finally, the analysis establish some possible scenarios post-NAFTA renegotiation and some strategic proposals for the SMEs
Computational studies on the rotamers of 4-aryl-2-oxo-1,2,3,4-tetrahydropyrimidines and 4-aryl-2-oxo-1,2-dihydropyrimidines
Authors: Memarian H.R. , Amini S.
Published: January 2019

The potential energy surface of 2-oxo-1,2,3,4-tetrahydropyrimidines (THPMs) is explored by density functional theory at the B3LYP level with a 6-31++G** basis set. All minimum and maximum points display a flat boat conformation of the heterocyclic ring in which the C4-aryl ring occupies a pseudo-axial position. In order to elucidate the comparative effect of the space orientation of the C4-aryl ring or the 5-CO group towards the heterocyclic ring on the total energy content of THPM and also the changes in some characteristic bond lengths and angles, these groups are rotated around the C4—C11 and C5—C7 single bonds, respectively. The results indicate an effect of the orientation of the 5-CO group on the investigated parameters compared to that of the C4-aryl ring. Natural bond orbital (NBO) analysis is carried out to investigate the effect of various intramolecular interactions and also intermolecular interactions with a medium in the calculation on the stabilization energy compared to those in the gas phase calculation. The results indicate that the dipole moments and also the charge densities on the specific atoms are effectively changed by the orientation of the C4-aryl ring and the 5-CO group towards the heterocyclic ring. In addition, bond rotations around the C4—C11 and C5—C7 single bonds in the oxidized compounds 2-oxo-1,2-dihydropyrimidines (DHPMs) are also carried out to compare the effects of these changes with those in THPMs.

This work aims at studying the influence of structural parameters on computations of the 93Nb quadrupolar interaction and chemical shift parameters in various niobates using first-principles approaches. We demonstrate that some of the computed NMR parameters, especially the isotropic chemical shift and the quadrupolar coupling constant, may differ either the X-ray crystal structure or a relaxed structure used for the calculation of the spectroscopic properties.

Геометрия координационных полиэдров диспрозия и гадолиния соответствует трехшапочной тригональной призме.
Dihydrogenphosphate anionic template-assisted hydrogen bonded networks in 2-benzylaminopyridinium and 4-ethyoxyanilinium dihydrogenphosphate salts
Authors: Jagan R. , Sivakumar K.
Published: January 2019

In the title compounds, namely 2-benzylaminopyridinium dihydrogenphosphate C12H13N2+⋅H2PO4–, (I) and 4-ethoxyanilinium dihydrogenphosphate C8H12NO+⋅H2PO4–, (II), the H2PO4– anions form a one-dimensional chain and a two-dimensional supramolecular sheet built through O—H⋯O hydrogen bonds. The asymmetric unit of II consists of two symmetry-independent molecules with almost similar geometrical parameters, differing in the orientation of cations with respect to the anions. The 2-benzylaminopyridinium cations of I are linked to the anionic one-dimensional chain, while the 4-ethoxyanilinium cations of II are anchored to the anionic two-dimensional sheet through N—H⋯O hydrogen bonds. These anion-cation interactions lead to the formation of an organic-inorganic supramolecular one-dimensional chain and two-dimensional sheets in I and II respectively. In dihydrogenphosphate salts the formation of anionic supramolecular motifs and networks are very much influenced by the nature of cations and their interaction with the H2PO4– anions.

Published: January 2019

The Cultural Policy of Kuno Klebelsberg and the Higher Education. The study presents the higher education policy of one of the best known and succesful Hungarian Minister of Religion and Education (1922–1931) Kuno Klebelsberg (1875–1932). As a politician of a state dismembered to one third of her original size-a consequence of the war loss and the Trianon peace treaty-he became a minister in miserable economic circumstances. With the contribution of him the stabilization of so-called refugee universities (from Kolozsvár and Pozsony to Budapest and then to Szeged [1921] and to Pécs [1923], the Academy of Minery and Forestry from Selmecbánya to Sopron [1918–1919]) could succesfuly be managed. Because of his conservative-liberal political attitude he tried to ease the effects of the so-called Numerus clausus Acts of 1920 which made the university entrance for Jewish Hungarians extremely serious. In 1928 he achieved the modification of that regulation. Instead of Budapest he supported the development of universities of Debrecen, Szeged and Pécs as a consequence of his well-grounded education policy based on decentralization. With his higher education policy he made great contribution to preserve the pre Great War Hungarian higher educational capacity in a dismembered Hungary lost 60% of her original population.
