Published: September 2019

Penelitian dilakukan pada sistem persediaan tabung gas LPG di PT. Wina Wira Usaha Jaya, Yogyakarta.  Saat ini perusahaan tersebut belum memiliki jadwal pasti untuk penebusan tabung gas dan hanya melakukan penebusan tabung LPG perhari tergantung pada tabung kosong yang tersedia. Terbatasnya penebusan tabung LPG serta permintaan konsumen yang tidak pasti sering menyebabkan kurangnya persediaan tabung LPG di gudang. Kekurangan dari permintaan baru bisa dipenuhi pada periode pemesanan berikutnya yang mengakibatkan beberapa konsumen beralih kepada agen lain untuk memenuhi kebutuhannya. Adapun tujuan dari penelitian ini adalah untuk menentukan periode pemesanan serta jumlah pemesanan tabung gas LPG supaya dapat  memenuhi permintaan konsumen.   Metode yang digunakan dalam penelitian ini adalah dengan menggunakan model periodic review (P). Metode periodic review ini digunakan untuk menentukan waktu periode pemesanan dan menentukan jumlah maksimal persediaan di gudang. Hasil analasis perhitungan biaya persediaan dengan menggunakan metode model periodic review ini akan dibandingkan dengan biaya persediaan yang dilakukan oleh perusahaan saat ini.   Berdasarkan dari hasil pengolahan data   dapat disimpulkan bahwa dengan menggunakan model periodic review didapatkan biaya persediaan yang lebih minimal.  Adapun system persediaan yang dilakukan adalah dengan cara sebagai berikut: periode pemesanan untuk tabung gas 12 kg adalah   0,0022 tahun (1 hari),  dan periode pemesanan untuk tabung gas 50 kg adalah  0,0192 tahun (7 hari).  Sedangkan jumlah  persediaan maksimal  untuk tabung gas ukuran 12 kg  adalah 817 tabung. dan untuk 50 kg adalah  79 tabung .  Dengan menggunakan system persediaan periodic review   maka  biaya persediaan berkurang 3,24 %. dari kebijakan perusahaan sebelumnya.
PENGEMBANGAN STRATEGI PEMESINAN BENTUK RONGGA SEGITIGA UNTUK MENGURANGI WAKTU PEMESINAN
Authors: Chaeron Mochammad Chaeron
Published: September 2019

Terdapat dua strategi untuk pemesinan bentuk rongga segitiga yaitu: direction parallel dan contour parallel. Kedua strategi tersebut masing-masing mempunyai kekurangan. Pada strategi direction parallel, untuk menyelesaikan pemesinan, harus ditambahkan lintasan pahat mengelilingi batas untuk menghilangkan scallop. Sedangkan pada strategi contour parallel, pemesinan harus dilakukan secara overlap untuk menghindari timbulnya daerah sisa pemesinan di tengah area bentuk rongga. Kedua hal tersebut menyebabkan terjadinya proses pemesinan berulang. Pengembangan terhadap strategi contour parallel dan direction parallel dilakukan untuk mengurangi sebanyak mungkin terjadinya proses pemesinan berulang itu. Penambahan ataupun penggantian lintasan pahat menjadi pilihan utama dalam pengembangan startegi ini.Pada akhirnya strategi hasil pengembangan berhasil memberikan lintasan pahat yang lebih pendek, yang berarti dengan menggunakan strategi hasil pengembangan, proses pemesinan bentuk rongga dapat dilakukan lebih cepat.

Extension of nodal diffusion solver of Ants to hexagonal geometry
Authors: Rintala A. , Sahlberg V.
Published: September 2019

The development of a new computational framework for core multi-physics problems, called Kraken, has been started at VTT Technical Research Centre of Finland Ltd. The framework consists of modular neutronics, thermal hydraulics and thermal mechanics solvers, and is based on the use of continuous-energy Monte Carlo reactor physics program Serpent. Ants is a new reduced order nodal neutronics program developed as a part of Kraken. The published methodology and first results of Ants has previously been limited to rectangular geometry steady state multigroup diffusion solutions. This work describes the solution methodology of Ants extended to hexagonal geometry steady state diffusion solutions. The first results using various two-dimensional and three-dimensional hexagonal geometry numerical benchmarks are presented. These benchmarks include the AER-FCM-001 and AER-FCM-101 three-dimensional VVER-440 and VVER-1000 mathematical benchmarks. The obtained effective multiplication factors of all considered benchmarks are within 18 pcm and the RMS relative assembly power relative differences are within 0.4% of the reference solutions.
Fuel cycles with PK-3+ FAs for VVER-440 reactors
Authors: Mikoláš P. , Vimpel J.
Published: September 2019

In order to increase the efficiency of fuel utilization at Dukovany NPP, the design of FA was changed by shroud removal and replacement with a structure called “Karkas”. Optimization of PK-3+ type FAs with different average enrichments was performed in order to find out those enrichment profiles with minimized non-uniform energy generation in FA (during burn-up). In addition, it was assumed that such a radial enrichment profile in FA could be achieved by making a change in the location of the fuel pin with a Gd2O3 burnable absorber – from the 2nd row to the 3rd row of pins from the edge of the fuel assembly on the fuel assembly diagonal. The aim of this study was to achieve a full quadruplicate cycle, every 15 months (approx. 450 days) at 1475 MWt nominal power. Preliminary results indicate that combination of PK-3+ and Gd-2M+ fuel assemblies does not show any unusual phenomena from the point of view of reactor physics. The proposed strategy is based on B1C33 cycle implemented at Dukovany NPP that is designed to be 395 FPDs. Already in the first “transient” cycle (34th) loaded with 60 fresh PK-3+ FAs and 12 Gd-2M++ CAs, the reached length at EOR is 424 FPDs, which means stretch-out 26 effective days. Averaged, the transition cycle stretch-out length is 23.5 effective days. For steady cycles, this average value is 19.2 effective days.

Neutron balance in two-component nuclear energy system
Authors: Blandinskiy V.
Published: September 2019

Most nuclear reactors under operation are thermal reactors, which consume 235U in once-through fuel cycle resulting in ineffective resource utilization and dramatic SNF volume growth. However, sustainable nuclear energy system (NES) should provide NFC closing for all hazardous radionuclides to minimize its life-time within NES and to make risk to be proportional to NES capacity, rather than total energy produced. These two basic principles require enough amount of neutrons for both energy generation and hazardous radionuclides transition to fission products. Therefore, taking into account politic, economic and technological risks and uncertainties, these issues can be solved in terms of two-component NES consisting of both thermal and fast reactors. In this work two methods to estimate neutron balance in NES are discussed. The fist method is based on the analysis of nuclear transformation chain due to radioactive decays and neutron induced reactions. The second one is the most complete one and relies on reaction rates comparison. Neutron balance estimation approach is demonstrated for two-component NES case study.
Criticality safety analysis for GNS IQ® – The Integrated Quiver System for damaged fuel
Authors: Chernykh M. , Amian D. , Tittelbach S. , Bannani A. , Cebula W. , Funke T. , Hüggenberg R.
Published: September 2019

The phase-out of nuclear energy in Germany has triggered the demand for a comprehensive solution to dispose of damaged fuel rods, normally remaining in the fuel pond until the final shutdown of the NPP. In order to establish a disposal concept for damaged fuel rods suitable for the needs of German utilities, GNS has developed a first of its kind solution, the Integrated Quiver System for Damaged Fuel (GNS IQ®), which can be loaded into the transport and storage casks of the CASTOR® family also by GNS. The GNS IQ® features a robust yet simple design with a high mechanical stability, a reliable leak tightness and large safety margins for future requirements on safety analysis. It can be easily adapted to a large variety of different damaged fuel rods and tailored to the specific needs of the customer. The quiver is adaptable e.g. in length and diameter for use in other types of transport and storage casks and is applicable in other countries as well. The paper gives a general overview of the disposal concept and provides a description of the Integrated Quiver System for Damaged Fuel with the focus on criticality safety assessment.
Rethinking the Role of the Armed Forces in Statebuilding: From Annihilation to Acceptance
Authors: Chandler David
Published: September 2019

This article analyses how international statebuilding has shifted from ‘problem-solving’ towards a new discursive regime of acceptance and affirmation. It seeks to explore how the shift to ‘bottom-up’ or ‘post-liberal’ approaches in the early 2000s led to a focus upon epistemological barriers to intervention and an appreciation of complexity. It then describes a process of reflection upon statebuilding as a policy practice, whereby the need to focus on local context and relations, in order to take problems seriously, begins to further undermine confidence in the Western episteme. In other words, the ‘bottom-up’ approach, rather than resolving the crisis of policy practices of statebuilding, seems to have further intensified it. It is argued that the way out of this crisis seems to be found in the rejection of the aspiration to know from a position of a ‘problem-solving’ external authority and instead to ‘unlearn’ from the opportunities opened up through the practices of exploring and engaging with the ‘other’.
The Role of Cyber-attacks in 21st Century War
Authors: Kassab Hanna Samir
Published: September 2019

Abstract         Deterrence theory states that world stability can be maintained if the costs of war far out-weigh its benefits. Weapons and strategies that make defense cheaper and offense more costly decrease the likelihood of conflict. Nuclear weapons may have thereby helped create the stability of the Cold War via the costs associated with launching first; according to this argument, war between the US and USSR never occurred because the price of war (i.e. mutual destruction) was too high. This theoretical paper will extend this argument to cyber-attacks and suggest that in order to maintain the security of a nation’s information technology, cyber-defense systems that correspond with Deterrence theory must be introduced. Cyber-attacks can be deterred if the proper system, a virus wall, is in place to counter any infiltration of a nation’s defense systems. This proposed virus wall would be a way to achieve stability from nation state cyber-attacks. Theoretical advancements of International Relations will also be proposed, specifically considering the area of Security Studies.

Authors: Neto Jacintho Maia
Published: September 2019

The dynamics of wars have demanded new challenges from the military. Acting on the whole spectrum of conflicts, in an environment that may not have winners, achieve goals with the lowest number of military and civilian casualties, with minimal material losses, and manage the chaos that comes after the conflicts, the major challenges for states and international organizations. Alongside these challenges, the military structure, in times of peace, needs to be adapted to its strategic environment, that is, to what is imposed on it by governments and the society it must protect. Flexible, specialized, and better equipped military structures have become, not only an operational requirement of the new asymmetric battlefield environment, but a requirement of society. It is understood that the main result of this work will be to present a proposal of how the Armed Forces and Brazilian society need to face these new challenges, ranging from aid to natural catastrophes, support for major events, acting in a police environment, and at the same time, be able to act in an external environment, markedly in UN missions or regional cooperation.

Time of superposition of the Arkansas River, Chaffee County, Colorado
Authors: Reinking Robert , Hoeksema Richard
Published: September 2019

Threemile Creek, a tributary to Colorado's upper Arkansas River, underwent two episodes of stream piracy during the Pleistocene. Recognition of the abandoned stream segments and determination of the time when each stream capture took place, permits determination of the position of the Arkansas River during the Pleistocene. This study reveals that it was established in its present channel In Browns Canyon by late Tertiary, thus discounting the suggestion of some authors that the Arkansas River flowed west of Browns Canyon during the Nebraskan stage. The study also suggests that more attention should be paid to abandoned tributary streams when determining the history of a major river.

Utilization and referral pattern at Sidamo Regional Hospital: A one-year prospective registration study in 1985/86
Authors: Lindtjorn Bernt
Published: September 2019

Hospitals can serve as important complement to Primary Health Care. Periodic reviews of hospital functions are therefore needed. We have reviewed hospital use and referral pattern at a regional hospital in southern Ethiopia. 85 % of admitted patients were from the region, and 2/3 from the local province. The effect of proximity on hospital use is shown but varied for the different patient groups. Patients from the local province were less often referred than patients from the remote provinces. The hospital functions mainly as a local hospital for the Sidamo Province and less as a referral hospital for the other parts of the region. The very large functional catchment area may worsen the local population's access to the hospital.

By reducing one of the basic images to the Riemann-Mellin contour integral for the modified Bessel functions and analyzing the corresponding inversion formula using the approaches of the complex variable function theory, an analytical form of the original original is found, which is abrupt in nature with a break point. It is shown that analytical solutions of the corresponding mathematical models using the found originals have a wave character, which is expressed by the presence of the Heaviside step function in the solutions. The latter means that at any time there is a region of physical disturbance to the point of discontinuity and an unperturbed area after the point of discontinuity. The images studied are included in the operational solutions of mathematical models in many areas of applied mathematics. physics, thermomechanics, thermal physics, in particular in the theory of thermal shock of viscoelastic bodies, in the study of the thermal reaction of solids based on the classical Maxwell-Cattaneo-Lykov-Vernott phenomenology, taking into account the final rate of heat propagation. These models are needed to study the thermal reaction of relatively new consolidated structurally sensitive polymeric materials in structures exposed to high-intensity external influences. The analytical relations obtained for the originals and the original improper integrals resulting from them, containing combinations of Bessel functions, can be used in the general methodology of constructing and applying various mathematical models in a wide range of external influences on materials in many fields of science and technology.

Published: September 2019

Oils of the dry seeds of Jatropha curcas and Tamarindus indica plants grown in Nigeria were obtained by maceration using n-Hexane. GC/MS analysis was performed using a Shimadzu QP2010plus series gas chromatography coupled with Shimadzu QP2010 mass spectroscopy detector. Characterization of constituents was done by comparison with the MS library (NIST) and further confirmed by interpreting the observed fragmentation pattern. Comparison of the mass spectra with the database on MS library revealed about 90-95% match. The antimicrobial screening of the oils were also performed for oils from the species: Jatropha curcas (Jatropha seeds) which was active against Aspergillus niger and Tamarindus indica (Tamarind) which showed antimicrobial activity against staphylococcus and Escherichia coli The most common major constituents of the fixed oils: were 14-methyl pendecanoic acid methyl ester 13.71%, 11-octadecanoic acid methyl ester 23.68%, Heptacosanoic acid methyl ester 10.22% and 9, 12-octadecadienoic acid methyl ester 17.44% for the Tamarindus indica While for Jatropha seeds oil 14- methylpentadecenoic acid methyl ester 12.31%, Hexadecanoic acid methyl ester 7.75%, 11- octadecanoic acid methyl ester 43.32% and 9- octadecenoic acid methyl ester 21.98% were obtained. Minimum inhibition concentrations of 12.50mg/ml were recorded for all test organisms by Jatropha seeds oil except for Escherichia coli which showed 6.25mg/ml. Both Tamarindus indica and Jatropha curcas showed minimum bactericidal activities at 12.50mg/ml were evaluated for all the samples. Recommendations for further research were also proffered.
A Review of Rain-Fed Wheat Production Constraints in Zambia
Authors: Tembo Batiseba
Published: September 2019

Wheat (Triticum aestivum L.) is an important food crop in Zambia. It is the second most widely grown cereal crop after maize. However, its production and productivity during summer rain season is limited by socio-economic, abiotic and biotic constraints. The socio-economic factors limiting high wheat yield are high cost of inputs, lack of improved rain-fed wheat seed, lack of affordable loans, lack of access to market information and poor mechanization. The abiotic constraints on the other hand include drought, high temperature and aluminium toxicity. Biotic constraints affecting rain-fed wheat production include various weeds, pests (aphids, grass hoppers, pink stalk borers and termites) and diseases (powderly mildew, loose smut, leaf rust, fusarium head blight and spot blotch). Termites being the most serious and destructive pest of rain-fed wheat. Spot blotch is the most devastating and widely distributed among the diseases causing high yield losses of between 7-100% followed by fusarium head blight. This review paper, looks at the factors that limit the production and productivity of rain-fed wheat among small holder farmers in Zambia.

Kulit buah naga merah (Hylocereus pilyrhizus) mengandung sanyawa antibakteri yang dapat menghambat pertumbuhan mikroorganisme. Dengan adanya senyawa antibakteri tersebut, kulit buah naga berpotensi untuk dijadikan bahan pengawet alami, untuk menggantikan penggunaan bahan pengawet kimia seperti Nitrit pada pengolahan se’i (daging asap khas Nusa Tenggara Timur). Hasil penelitian menunjukkan bahwa ekstrak kulit buah naga mampung menghambat pertumbuhan bakteri patoogen seperti E.coli ATCC 25922 dan bakteri S.aureus ATCC 25923. Perbedaan perlakuan bakteripatogen yang diberikan berpengaruh nyata terhadap diameter zona hambat aktivitas antibakteri jus kulit buah naga merah (P<0.05). Penggunaan jus kulit buah naga sebagai bahan curing pada se’i dapat menghambat pertumbuhan bakteri dan memperpanjang masa simpan sampai pada hari ke enam pada suhu ruang. Dapat disimpulkan bahwa penggunaan jus kulit buah naga sebagai bahan curing pada se’i dapat menghambat pertumbuhan bakteri sehingga mampu memperpanjang masa simpan se’i pada suhu ruang.
