A Mass Balance Approach in Sediment Budgeting of Large Alluvial Rivers with special emphasis on the Brahmaputra in Assam

Morphology of an alluvial river channel is the consequence of erosion, sediment transport and sedimentation in a river. Sediment budget accounts for the sources, sinks and redistribution pathways of sediments, solutes and nutrients in a unit region over unit time. Human activities are the most important factors that affect the variation in the pattern of river sediment load. This paper discusses sediment budget of a few large rivers by review of literature and estimation of sediment budget of Brahmaputra River in Assam using mass balance approach. An attempt has also been made to discuss human and climatic impact on sediment load of major rivers of the world. Total sediment load in the Brahmaputra River at downstream location (India-Bangladesh border) was estimated to be 814×106 t/year. Considering 10% of sediment load of the Brahmaputra as bed load, suspended sediment load at downstream was estimated to be 733×106 t/year. Tributaries, bank erosion and scouring of river bed were found to contribute 52%, 27% and 21% respectively to sediment load of Brahmaputra at downstream locations. In spite of limitations of the dependable data, future complexity due to climate change impact and hydropower dam initiative in upstream of the River, the study is a simplified approach in sediment budgeting of the Brahmaputra.

Cryo-EM structure provides insights into the dimer arrangement of the O-linked β-N-acetylglucosamine transferase OGT

The O-linked β-N-acetylglucosamine modification is a core signalling mechanism, with erroneous patterns leading to cancer and neurodegeneration. Although thousands of proteins are subject to this modification, only a single essential glycosyltransferase catalyses its installation, the O-GlcNAc transferase, OGT. Previous studies have provided truncated structures of OGT through X-ray crystallography, but the full-length protein has never been observed. Here, we report a 5.3 Å cryo-EM model of OGT. We show OGT is a dimer, providing a structural basis for how some X-linked intellectual disability mutations at the interface may contribute to disease. We observe that the catalytic section of OGT abuts a 13.5 tetratricopeptide repeat unit region and find the relative positioning of these sections deviate from the previously proposed, X-ray crystallography-based model. We also note that OGT exhibits considerable heterogeneity in tetratricopeptide repeat units N-terminal to the dimer interface with repercussions for how OGT binds protein ligands and partners.

Efek Mediasi Motivasi Atas Hubungan Etos Kerja Terhadap Kinerja Pegawai Dinas Kehutanan UPT. Kesatuan Pengelolaan Hutan Wilayah II Pematangsiantar

The purpose of this study was to determine the description of motivation, work ethic and employee performance at the Forest Service Unit of UPT. Forest Management Unit Region II Pematangsiantar and to determine the effect of motivation on the relationship of work ethic on employee performance at the Forest Service Unit of UPT. Forest Management Unit Region II Pematangsiantar. This research uses the design of library research and field research. The population in this study were UPT Forest Service employees. The Pematangsiantar Region II Forest Management Unit totaling 67 employees. The type of data used is qualitative and quantitative data. Data sources used are primary data and secondary data. Data collection is done by questionnaire, interview and documentation. The analysis technique used is the classic assumption test with validity, reliability and normality tests, qualitative descriptive analysis and quantitative descriptive analysis with path analysis and hypothesis testing. The results of the study concluded that the work ethic has a significant effect on employee performance. Motivation has a significant effect on employee performance and motivation is able to mediate the relationship of work ethics on employee performance.

ANALISIS KESIAPAN PENERAPAN POLA PENGELOLAAN KEUANGAN BADAN LAYANAN UMUM DAERAH (PPK-BLUD) DI UPTD BALAI KESEHATAN INDERA MASYARAKAT (BKIM) PROVINSI SUMATERA BARAT TAHUN 2016

Regional Public Service Regency (RPSR) to provide services to the community without priority to seek profits, with existing data in unit Region Indra Center of West Sumatra Province has not been optimal yet in financial management, lack of the services have not standards, this study aims to evaluate the readiness of the implementation of the Financial Management Regional Public Service Regency (RPSR) at unit region Indra Centre of West Sumatera Province in 2016. This study uses qualitative study conducted in May to October 2016, with informants as much as 6 (six), data collection using indepth interview, document review and observation, analyzed by triangulation method and source. The results of the research show that the inputs are not well available yet, namely the regulations related to the implementation of the Financial Management Model of the Regional Public Service Regency (RPSR), human resources, limited budget, facilities and infrastructures are not yet eligible. In the process of substantive requirements have been eligible, technical requirements of service performance is quite good. and administrative requirements by assessing 6 documents have > 60% that is with a value of 80.3% which means the documents qualify administrative requirements. The conclusion of the study on the implementation of the Financial Management Model of the Regional Public Service Rgency (RPSR) at Unit Region Indra Centre West Sumatra, Unit Region Indra Centre is able to implement the full RPSR. Researchers suggest that it is necessary to draft the West Sumatra governor’s regulation on RPSR and complete administrative documents and improve the quality of services through improved management.

Health Political Communication After the Issuance of Presidential Regulation No. 18 Year 2016: a Case Study in RSUD Kabupaten Karawang

Amendment to Government Regulation number 18 of 2016 begins with the issuance of Law Number 23 Year 2014 on Regional Instrument Organization to replace Law no. 32 year 2014. In this study, researchers used qualitative methods with Case Study approach, the researchers considered this method is very appropriate that best describe the phenomenon in political communication research related to post-implementation of Government Regulation No. 18 of 2016. Ability to provide rich portraits which is the main benefit of case studies. The research reader should be made to feel as if you were there with you in your research, see what you see, summarize what you have concluded. This research was conducted in Public Hospital Karawang regency. In this study researchers found that: 1. Hospital changed the status that was originally Regional Technical Institute into Limited Service Unit Region under the health service 2. The Director is a physician or dentist whose functional status is then given an additional duty to become the Director of the Hospital 3. The Health Office is a member of the hospital supervisory board as well as the operational operator of the hospital has resulted an overlapping coordination in organizational communication

Comparative Characterization of Complete and Truncated Forms of Lactobacillus amylovorus α-Amylase and Role of the C-Terminal Direct Repeats in Raw-Starch Binding

ABSTRACT Two constructs derived from the α-amylase gene (amyA) of Lactobacillus amylovorus were expressed inLactobacillus plantarum, and their expression products were purified, characterized, and compared. These products correspond to the complete (AmyA) and truncated (AmyAΔ) forms of α-amylase; AmyAΔ lacks the 66-kDa carboxyl-terminal direct-repeating-unit region. AmyA and AmyAΔ exhibit similar amylase activities towards a range of soluble substrates (amylose, amylopectin and α-cyclodextrin, and soluble starch). The specific activities of the enzymes towards soluble starch are similar, but the KM andV max values of AmyAΔ were slightly higher than those of AmyA, whereas the thermal stability of AmyAΔ was lower than that of AmyA. In contrast to AmyA, AmyAΔ is unable to bind to β-cyclodextrin and is only weakly active towards glycogen. More striking is the fact that AmyAΔ cannot bind or hydrolyze raw starch, demonstrating that the carboxyl-terminal repeating-unit domain of AmyA is required for raw-starch binding activity.
