Absorption and Circular Dichroism Spectra of Molecular Aggregates with the Full Cumulant Expansion.
Authors: Cupellini Lorenzo , Lipparini Filippo , Cao Jianshu 
Published: June 2020

The exciton Hamiltonian of multichromophoric aggregates can be probed by spectroscopic techniques such as linear absorption and circular dichroism. In order to compare calculated Hamiltonians to experiments, a lineshape theory is needed, which takes into account the coupling of the excitons with inter- and intramolecular vibrations. This coupling is normally introduced in a perturbative way through the cumulant expansion formalism, and further approximated by assuming a Markovian exciton dynamics, for example with the modified Redfield theory.Here we present an implementation of the full cumulant expansion (FCE) formalism [Ma and Cao, J. Chem. Phys. 2015, 142, 094106 ] to efficiently compute absorption and circular dichroism spectra of molecular aggregates beyond the Markov approximation, without restrictions on the form of the exciton-phonon coupling. By employing the LH2 system of purple bacteria as a challenging test case, we compare the FCE lineshapes with the Markovian lineshapes obtained with the modified Redfield theory, showing that the latter present a much poorer agreement with experiments. The FCE approach instead accurately describes the lineshapes, especially in the vibronic sideband of the B800 peak. We envision that the FCE approach will become a valuable tool for accurately comparing model exciton Hamiltonians with optical spectroscopy experiments.

Published: June 2020

<p>Parijoto <em>(Medinilla speciosa)</em> tumbuh subur dan tumbuh liar di lereng-lereng gunung atau di hutan-hutan pada tanah yang berhumus tinggi dan lembab di lereng gunung mulai pada ketinggian 700 hingga 2.300 meter diatas permukaan laut. Salah satu lokasi paling banyak ditemukan tanaman parijoto terdapat di lereng Pegunungan Muria, Desa Colo, Kecamatan Dawe, Kabupaten Kudus, Jawa Tengah. Buah parijoto mengandung senyawa fenolik dan flavonoid yang tinggi, diharapkan buah parijoto dapat digunakan sebagai alternatif pengganti antioksidan sintetik seperti <em>Buttylated Hydroxyanisol</em> (BHA) dan <em>Butilated Hydroxytoluen</em> (BHT). Senyawa BHA dan BHT sejak lama belum diterima sepenuhnya oleh konsumen karena dianggap berbahaya bagi kesehatan tubuh karena dianggap mengandung zat karsinogenik. Penggunaan buah parijoto sebagai antioksidan alami ke dalam makanan, minuman atau produk lainya dalam bentuk utuh maupun irisan sangat tidak efisien. Untuk itu perlu dilakukan tahap ekstraksi buah parijoto. Ultrasonic Assisted Extraction (UAE) adalah salah satu metode ektraksi dengan bantuan gelombang ultrasonik. metode ini adalah metode alternatif ekstraksi non-termal yang lebih efisien, lebih cepat, dan memungkinkan pengurangan pelarut, sehingga menghasilkan ekstrak murni dan yield yang lebih tinggi dibandingkan dengan ekstraksi konvesional. Untuk dapat meningkatkan efek yang optimum penggunaan ekstrak parijoto, diperlukan kondisi bahan yang baik, yaitu seperti bentuk sediaan nanoemulsi. Nanoemulsi merupakan partikel koloid padat dengan diameter 1-1000 nm. Dengan ukuran tersebut, globul-globul dapat terpenetrasi baik dan menembus lapisan pori bahan yang akan dicoating, sehingga ekstrak parijoto yang terlarut dalam globul akan banyak berpenetrasi. Sifat fisik dan stabilitas emulsi dipengaruhi oleh jenis dan konsentrasi emulgator. Jenis emulgator, Tween 80 dipilih dalam penelitian ini. Adanya emulgator yang ditambahkan akan menghasilkan monolayer yang mengelilingi droplet. Komposisi dari emulgator akan dikaji lebih lanjut, dimana Tween 80 yang memiliki nilai HLB 15 akan ditambahkan dengan beberapa variasi konsentrasi.</p>

Cerebral palsy is a neurological, non-progressive and commonest cause of severe physical disabilities. It affects body movement and muscle coordination permanently and usually appears in early childhood. Children with cerebral palsy have severe problems of fine motor skills. The research was conducted to achieve the following objectives 1) to identify the current level of fine motor skills of students with cerebral palsy studying in the schools, 2)Design an intervention strategic plan to enhance the fine motor skills of children with cerebral palsy,3)implement the prescribed intervention plan to enhance the fine motor skills of children with cerebral palsy.4)improve the fine motor skills of children with cerebral palsy by implementing the intervention strategies. It was an experimental research conducted by applying single subject research design (ABA).The researchers used two different checklists to assess the functional abilities of the children with CP before and after intervention. The reliability of all the instruments was checked by using cronbach alpha (.87 and .78) whereas the content validity of the instruments was estimated by taking expert opinions. On the basis of pretest an intervention plan was implemented to enhance the functional abilities of the students. A self-developed test was used after implementing the intervention strategies to see the improvement in the functional abilities of children with cerebral palsy.

O Projeto Cisternas nas Escolas objetiva o fornecimento de água para as escolas rurais do Semiárido, utilizando ações estruturais mediante concepção de cisternas como tecnologia social para armazenamento de água pluvial, e ações não estruturais por meio de práticas educativas contextualizadas. Este trabalho objetiva apresentar um pioneiro diagnóstico da infraestrutura dos serviços de abastecimento de água as escolas rurais em que foram implantadas cisternas do Programa Cisternas nas Escolas na Microrregião Serrana dos Quilombos, no estado de Alagoas, especificamente no município de Santana do Mundaú, utilizando-se como metodologia a pesquisa exploratória e qualitativa, com emprego de entrevista semiestruturada e não estruturada, além do uso de questionário, fichas-relatório e registros fotográficos. Das cisternas implantadas nas escolas, apenas uma está sendo parcialmente utilizada. Estão todas elas totalmente desprovidas de acompanhamento técnico, sendo possível perceber a falta de interesse do executivo municipal na promoção da manutenção desses equipamentos. São fundamentais ações que elevem o empoderamento social a essas construções. Cistern in Schools Program: case study in the mountainous microregion of quilombos in the state of Alagoas, Brazil The reality of many rural schools in the public system presents a still worrying scenario regarding access to water. The Cisterns in Schools Project aims to provide water for rural schools in the Semi-Arid and priority areas located in indigenous villages and quilombola communities, using structural actions through the design of cisterns as social technology for rainwater storage, and non-structural actions through contextualized educational practices. The work aims to present a pioneering diagnosis of the infrastructure of water supply services to rural schools in which cisterns of the Cisterns in Schools Program were implemented in the mountainous dos Quilombos Microregion in the state of Alagoas, specifically in the municipality of Santana do Mandau. The methodology was based on exploratory and qualitative research using semi-structured and unstructured interviews, using a questionnaire, report cards and photographic records. Of the cisterns installed in schools, only one is being partially used. They are all totally devoid of technical monitoring, being possible to perceive the lack of interest of the municipal executive in promoting the maintenance of this equipment.

Background Worldwide efforts have increased to understand what works in policy implementation, for whom and under what circumstances (context) are health policies useful and effective. All countries are striving towards Universal Health Coverage (UHC). Reforms are being implemented to ensure no-one is left behind. Methods We draw on our experiences of tracking implementation of policies aimed at achieving UHC in a national health insurance (NHI) pilot district (universal coverage in Tanzania and South Africa). Policies aimed at achieving UHC were tracked from 2011-2015 to understand why there are varying UHC policy implementation states and outcomes among facilities in the same district? Results Lessons learned in the process include: i) to adopt or adapt policy is a process – actors at the front-line seem to engage with policy, carry out a policy-context audit, try to engage with superiors if there are discrepancies between policy and context and eventually take a decision to adopt or adapt policy; ii) local facility contexts matter and vary – decision to implement policy is influenced by the conditions on the ground, hence implementation states can vary from one facility to the other despite being in the same district; iii) implementation states range from full policy adoption and implementation, policy adaptation and partial implementation, delayed implementation to non-implementation; iv) a resource audit before policy is implemented could go a long way in reducing policy-practice gaps; and v) Policy implementation states are dynamic subject to change – for example, when equipment breaks down and is not replaced immediately. Conclusion There seems to be inherent respect among implementing actors, for the department of health and people above them. They are however concerned with the fact that they are removed from the ground, could have lost touch with realities on the ground, hence the policy directives sent from the top, are often not congruent with ground conditions. Actors revealed how they engage with the policy, assess what they are being asked to do and compare that with the existing resources. To adopt or adapt policy in a UHC context: there seems to be a series of steps actors take.

PERBANDINGAN KONSTITUSIONAL : PENGATURAN IMPEACHMENT DI INDONESIA DAN ITALIA
Authors: Zulhidayat Muhammad 
Published: June 2020

Mekanisme pemberhentian Presiden dalam masa jabatan melalui impeachment process awalnya dikenal di dalam Hukum Tata Negara Amerika Serikat, lalu berkembang sehingga diikuti oleh negara-negara yang menganut sistem demokrasi, diataranya Indonesia dan Italia. impeachment sendiri dapat diartikan sebagai tuduhan atau dakwaan. Sehingga impeachment lebih menitikberatkan pada prosesnya dan tidak harus berakhir dengan berhenti atau turunnya Presiden atau pejabat tinggi negara tersebut dari jabatannya. Mekanisme ini dinilai sebagai wujud saling mengawasi satu sama lain antar lembaga eksekutif, legislatif dan yudikatif. Dalam jurnal ini rumusan masalah yang diangkat adalah bagaimanakah perbandingan mekanisme impeachment Presiden dan/atau Wakil Presiden antara sistem ketatanegaraan di Indonesia dan Italia ?, Penelitian dalam jurnal ini menggunakan metode pendekatan yang bersifat Perbandingan Hukum (comparative law). Simpulan dalam penelitian ini adalah Indonesia dan Italia sama-sama melibatkan DPR dan Mahkamah Konstitusi. Akan tetapi, secara mekanisme kedua negara mempunyai impeachment process yang berbeda. Saran dalam penelitian ini adalah Indonesia harus mengatur lebih jelas terkait syarat-syarat Presiden dan/atau wakil presiden bisa di-impeach. Hal ini dikarenakan dalam UUD Tahun 1945 Pasal 7A tidak menjelaskan terkait perbuatan tercela seperti apa sehingga menyebabkan Presiden dan/atau Wakil Presiden bisa dilakukan Impeachment Process.

Yu. Nedava initiated the development of the concept of VDK processing of semen of farm animals, determined their purpose in the system of conservation of genetic resources of farm animals, substantiated the importance of using such materials as the main link in the conservation of farm animals.
Distortion of Gears as Consequence of Lightweight Construction – Influence of Teeth*
Authors: Lübben Th. , Kagathara J. 
Published: June 2020

Abstract
On the basis of economic and ecological constraints a reduced weight and/or minimized volume of automobile components is more and more focused in industrial and scientific activities in recent years. Apart from the application of new materials with considerably lower density a change of component design can be used to succeed in aims regarding lightweight construction. But aspects of a production-oriented design, especially for heat treated drive train components, have to be considered, too. This topic applies in particular to the final heat treatment because serious distortion problems can arise due to reduced stiffness and asymmetric mass distribution of a component. In the previous research work, the distortion behavior of gear base bodies as essential part of a gear was analyzed and a first design guideline for gear base bodies resulting in tolerable distortion was developed. In the ongoing research work, the basic approaches used for the determination of this guideline for gear base bodies will be applied to a complex gear with strong asymmetric mass distribution. One of the first questions of this work concerns the influence of the teeth on base body distortion. In this paper results of comparitive experiments between a complexed shaped gear with and without teeth will be presented.

Published: June 2020

BACKGROUND: The cardiovascular response to resistance training is influenced by different variables such as intensity and volume. OBJECTIVE: To compare the effects of resistance training sessions differing in level of effort on blood pressure and arterial stiffness. METHODS: Thirty-two men performed 3 sets at 75% of 1-RM during the bench press and squat exercises to failure ([Formula: see text] 16; high-effort group), or performing half of the maximum possible number of repetitions per set ([Formula: see text] 16; low-effort group). Blood pressure (systolic blood pressure [SBP], diastolic blood pressure [DBP], and mean arterial pressure [MAP]) and arterial stiffness (pulse wave velocity [PWV]) were measured before training (Pre), immediately after training (Post 1), 5 minutes after training (Post 2), and 24 hours after training (Post 3). RESULTS: A main effect of time ([Formula: see text] 0.012) was observed for all variables due to higher values at Post 1 compared to Post 2 (effect size [ES] range: 0.34–1.37) and Post 3 (ES range: 0.37–0.92). When compared to Pre, increases higher than a ES of 0.20 were observed for the high-effort group compared to the low-effort group at all time points. CONCLUSIONS: Training to failure should be discouraged to avoid acute increases in blood pressure and arterial stiffness.

OBJECTIVE: To evaluate the utility of radiomics analysis for differentiating benign and malignant epithelial salivary gland tumors on diffusion-weighted imaging (DWI). METHODS: A retrospective dataset involving 218 and 51 patients with histology-confirmed benign and malignant epithelial salivary gland tumors was used in this study. A total of 396 radiomic features were extracted from the DW images. Analysis of variance (ANOVA) and least-absolute shrinkage and selection operator regression (LASSO) were used to select optimal radiomic features. The selected features were used to build three classification models namely, logistic regression method (LR), support vector machine (SVM), and K-nearest neighbor (KNN) by using a five-fold cross validation strategy on the training dataset. The diagnostic performance of each classification model was quantified by receiver operating characteristic (ROC) curve and area under the ROC curve (AUC) in the training and validation datasets. RESULTS: Eight most valuable features were selected by LASSO. LR and SVM models yielded optimally diagnostic performance. In the training dataset, LR and SVM yielded AUC values of 0.886 and 0.893 via five-fold cross validation, respectively, while KNN model showed relatively lower AUC (0.796). In the testing dataset, a similar result was found, where AUC values for LR, SVM, and KNN were 0.876, 0.870, and 0.791, respectively. CONCLUSIONS: Classification models based on optimally selected radiomics features computed from DW images present a promising predictive value in distinguishing benign and malignant epithelial salivary gland tumors and thus have potential to be used for preoperative auxiliary diagnosis.
