Published: July 2018

Pendistribusian produk berperan penting dalam dunia industri. Salah satu usaha yang dapat dilakukan perusahaan untuk mengoptimalkan pendistribusian produk adalah meminimalkan biaya tranportasi melalui penentuan rute optimal kendaraan yang disebut dengan VRP (Vehicle Routing Problem). Tujuan dari VRP adalah menentukan rute optimal yaitu rute dengan jarak minimum untuk mendistribusikan produk kepada konsumen. Salah satu variasi VRP adalah Capacitated Vehicle Routing Problem (CVRP), yaitu VRP dengan kendala kapasitas kendaraan. Kasus CVRP tersebut dapat diselesaikan dengan menggunakan Algoritma Tabu Search. Cara kerja Algoritma Tabu Search dimulai dengan penentuan initial solution menggunakan Nearest Neighbor, evaluasi move menggunakan Exchange, 2-Opt, Relocated, dan Cross Exchange, update Tabu List, kemudian apabila kriteria pemberhentian terpenuhi maka proses Algoritma Tabu Search berhenti jika tidak, maka kembali pada evaluasi move. Proses perhitungan Algoritma Tabu Search dilakukan secara manual pada PT IAP. Setiap perusahaan distributor atau pun jasa selalu mengadakan persediaan, salah satunya adalah Safety Stock. Perhitungan sederhana Safety Stock dapat membantu menyelesaikan persediaan pengaman yang harus dipersiapkan perusahaan untuk mengurangi tingkat kerugian. Berdasarkan proses perhitungan manual diperoleh solusi pendekatan optimal yaitu rute dengan total jarak terpendek sebesar 138,834 km dan nilai untuk Safety Stock adalah ± 9 karton.

One of the varieties of VRP is Capacitated Vehicle Routing Problem (CVRP), which is VRP with vehicle capacity problems. CVRP case can be solved by using Tabu Search Algorithm. How it works Tabu Search Algorithm starts with the determination of the initial solution using the Nearest Neighbor, evaluating the move using Exchange, 2-Opt, Relocated, and Cross Exchange, updates Tabu List, then when the criteria for termination are met then the Tabu Search algorithm stop if not, then go back to the evaluation of the move. Tabu Search Algorithm calculation process is done manually PT IAP. Every distributor or service company always hold inventory, one of them is Safety Stock. The simple calculation of Safety Stock can help solve the safety availability that should be prepared by the companies and reduce the level of losses. Based on the manual calculation process obtained optimal solution approach that is route with the shortest route to the optimal total distance of 138,834 km and the value of safety stock is ± 9 cartons.]

Rotation in sdB stars as revealed by stellar oscillations
Authors: Charpinet Stephane , Giammichele Noemi , Zong Weikai , Van Grootel Valérie , Brassard Pierre , Fontaine Gilles 
Published: July 2018

Abstract
An interesting opportunity offered by the detection of stellar oscillations is the possibility to infer the internal rotation rate of a star through the so-called rotational splittings. Such seismic measurements remained rather scarce for hot B subdwarf (sdB) stars until the advent of space observations with the Kepler spacecraft. Nowadays, however, a number of rotation measurements have become available, offering a glimpse on the global rotational properties of sdB stars. Here, we briefly discuss what asteroseismology starts to reveal on the rotation rate of these stars. We also make connections with the internal rotation of red-giant and white-dwarf stars. In particular, we show that the very slow rotation rates derived for single sdB stars, and their similarities with the dynamical properties of the cores of red-clump stars, strongly suggest that they evolved from red-giants rather than merger events.We also point out that no more angular momentum seems to be lost by stellar cores throughout the helium burning phase until the cooling white-dwarf stage, indicating that all the braking occurs before, most likely during red-giant branch evolution.
The genus Rosenvingea (Phaeophyceae: Scytosiphonaceae) in south-west Australia, with the description of Rosenvingea australis sp. nov.
Authors: Huisman John M. , Boo Ga Hun , Boo Sung Min 
Published: July 2018

Abstract
Two species of the brown algal genus Rosenvingea are reported from south-west (SW) Australia, including the widely distributed R. orientalis and the new species R. australis Huisman, G.H. Boo et S.M. Boo, sp. nov. Molecular phylogenies of mitochondrial cox3 and plastid psaA unequivocally align the SW Australian R. orientalis with specimens from Vietnam and the species is morphologically consistent throughout its Australian range. Australian specimens of the new species R. australis join with a specimen from New Caledonia and these resolve as a sister species to R. intricata, with levels of pairwise divergence (4.2–4.9% in cox3 and 3.9–4.0% in psaA) comparable to those between other scytosiphonacean species. The new species can be distinguished morphologically by its branch dimensions and the arrangement and size of plurangia, but further studies including molecular analyses of a full range of species and possible morphological variants are needed.
Evidence for the positive impact of ISO 9001 and ISO 15189 quality systems on laboratory performance – evaluation of immunohaematology external quality assessment results during 19 years in Austria
Authors: Buchta Christoph , Coucke Wim , Mayr Wolfgang R. , Müller Mathias M. , Oeser Reinhard , Schweiger Christian R. , Körmöczi Günther F. 
Published: July 2018

Abstract

Background
ISO 9001 and ISO 15189 have been established as continuative models for quality systems beyond national laws, mandatory standards and guidelines of expert associations regarding analytical and organisational performance of medical laboratories and transfusion services. Although widely used, their impact on laboratory performance has not been investigated.

Methods
We retrospectively analysed the results of 167 laboratories in 59 distributions of the Austrian red cell immunohaematology external quality assessment (EQA) scheme in the years 1999–2017. The performance for each parameter and trends of individual participants were compared with respect to certification or accreditation status of participants’ quality systems and to laboratory type.

Results
Considering more than 52,000 EQA results, the absence or presence of a laboratory quality management system showed different error rates. Laboratories with ISO 9001 or ISO 15189 certification/accreditation had 0.7% incorrect results, while this rate was doubled without such quality systems (1.4%, p=0.0002). Statistically significant error reductions were seen upon ISO 9001/ISO 15189 implementation (1.3% before vs. 0.7% after; p=0.0468). Transfusion services had fewer errors (0.9%) compared to hospital and independent laboratories (both 1.2%).

Conclusions
Implementation and maintenance of quality systems according to ISO 9001 or ISO 15189 as well as laboratory specialisation result in better analytical performance as can be seen in immunohaematology EQA results. The conclusion is that these results apply to other laboratory tests and perhaps to other areas of health care.
Mode switching phenomenon in geometrically nonlinear free vibration analysis of in-plane inhomogeneous plates on elastic foundation
Authors: Lohar Hareram , Mitra Anirban , Sahoo Sarmila 
Published: July 2018

Abstract
Effect of geometric nonlinearity onfree vibration behaviour of a non-uniform in-plane inhomogeneousplate on elastic foundation is carried out with an emphasis on mode switching phenomenon. The formulation is semianalytic displacement based and it is carried out in two distinct steps. First, the static problem is solved to find out the unknown displacement field by using minimum total potential energy principle. Secondly, subsequent dynamic problem is set up as an eigenvalue problem on the basis of the known displacement field. The governing set of equations in dynamic problem is obtained by using Hamilton’s principle. In static analysis, unknown co-efficient of the governing equations are solved using an iterative method, which is direct substitution with relaxation method. The dynamic problem is solved with the help of intrinsic Matlab solver. The results of the present method are validated with existing data. Backbone curve corresponding to different combinations of systemparameters are presented in non-dimensional plane.Mode switching is observed to occur in certain specific situation. The linear and nonlinear mode shapes are also furnished to support the presence of switching phenomenon.
Address inversion in Swahili: Usage patterns, cognitive motivation and cultural factors
Authors: Kraska-Szlenk Iwona 
Published: July 2018

AbstractAddress inversion occurs in many languages of the world and involves figurative use of kinship terms in the “reversed” meaning. In pragmatically defined contexts, a son can be called ‘daddy’, a daughter ‘mummy’, etc. The article explains general cognitive mechanisms underlying this widespread linguistic behavior, drawing parallels to other strategies based on opposition and used to express positive emotions. A detailed case study of Swahili will demonstrate that the phenomenon of address inversion is best understood, when a cognitive analysis takes into account a full sociolinguistic and cultural context. In addition, variation observed in Swahili usage patterns of address inversion provides insights into paths of semantic change which some kinship terms have undergone evolving into general words of endearment or discourse markers. The article contributes to cognitive linguistic research on emotions and words of endearment, and to studies on polysemy of kinship terms. The results shed light on general issues of language-culture interface and sociolinguistic contexts of semantic change.
Bacon’s New Atlantis and the Fictional Origins of Organised Science
Authors: Lucas Peter 
Published: July 2018

Abstract
It is a commonplace that science fiction draws inspiration from science fact. It is a less familiar thought-though still widely acknowledged-that science has sometimes drawn its inspiration from science fiction. (Arthur C. Clarke’s idea of geostationary communications satellites is a well-known example.) However, the debt of science to science fiction extends beyond such specific examples of scientific and technological innovations. This essay explores the paradoxical-sounding thesis that science itself, as we now know it, was originally the product of a science fiction vision. At a time when the collective endeavours of early modern researchers amounted to something less than science, Francis Bacon’s New Atlantis (1627) helped show what wonders might be achieved by organised and methodical state-sponsored scientific research. Bacon’s vision was highly prescient: many of the scientific possibilities he sketched have since become realities. It was also highly influential: early modern science bears the characteristic stamp of Bacon’s vision, and that same influence is discernible right down to the present day.
Cognitive error in an academic emergency department
Authors: Schnapp Benjamin H. , Sun Jean E. , Kim Jeremy L. , Strayer Reuben J. , Shah Kaushal H. 
Published: July 2018

Abstract

Background
Medical error is a leading cause of death nationwide. While systems issues have been closely investigated as a contributor to error, little is known about the cognitive factors that contribute to diagnostic error in an emergency department (ED) environment.

Methods
Eight months of patient revisits within 72 h where patients were admitted on their second visit were examined. Fifty-two cases of confirmed error were identified and classified using a modified version of the Australian Patient Safety Foundation classification system for medical errors by a group of trained physicians.

Results
Faulty information processing was the most frequently identified category of error (45% of cases), followed by faulty verification (31%). Faulty knowledge (6%) and faulty information gathering (18%) occurred relatively infrequently. “Misjudging the salience of a finding” and “premature closure” were the individual errors that occurred most frequently (13%).

Conclusions
Despite the complex nature of diagnostic reasoning, cognitive errors of information processing appear to occur at higher rates than other errors, and in a similar pattern to an internal medicine service despite a different clinical environment. Further research is needed to elucidate why these errors occur and how to mitigate them.
New Approach for n-Hexadecane Biodegradation by Sol-Gel Entrapped Bacterial Cells
Authors: Chernev Georgi , Christova Nelly , Kabaivanova Lyudmila , Nacheva Lilyana 
Published: July 2018

Abstract
In this study sol-gel hybrid materials in the system SiO2-chitosan (CS) - polyethylene glycol (PEG), as novel structures with potential application in bioremediation were investigated. The organic components - CS and PEG were used as structural modifiers for functionality improvement. The catabolic activity to n-hexadecane of Pseudomonas aeruginosa BN10 free and immobilized cells was estimated. The cell immobilization technique was employed to evaluate its efficiency on biodegradation and protective effect from high levels of hydrocarbons. The characteristics of obtained hybrid materials were investigated via X-ray Diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Atomic-force microscopy (AFM) analyses. The obtained results revealed that the organic part in the synthesized hybrids is important for microstructure and defined properties creation. The rate of n-hexadecane mineralization by the bacterial strain was influenced by variation in cell densities applied in the immobilization procedures. Semi-continuous processes with multiple xenobiotic supplies were carried out. The synthesized by the sol-gel method hybrid matrices proved to be suitable carriers for realizing an effective biodegradation process of n-hexadecane by Pseudomonas aeruginosa BN10. Biodegradation of 50 kg/m3 of n-hexadecane was realized by free cells. Significantly greater quantity (150 kg/m3) was mineralized for 15 active cycles by entrapped bacterial cells. Biodegradation process with gradual increase of xenobiotic concentration reaching 30 kg/m3 for 120 h was also accomplished.

Published: July 2018

Abstract
Antagonistic activity of microorganisms against phytopathogens is mainly the results of plants’ health improvement due to the inhibition of pathogens growth and the induction of plants resistance against diseases. The aim of the research was to determine antagonistic properties of Pantoea agglomerans against Rhizoctonia solani. The properties of two strains P. agglomerans BC17 and BC45 were assessed according to the following criteria: mycelial growth of R. solani in the presence of bacterial metabolites, an impact of P. agglomerans on the growth of sugar beet in the pots containing soil with and addition of R. solani and without it, the ability to produce indole-3-acetic acid (IAA). It has been recorded that antagonistic properties of tested strains are different. In the presence of metabolites of BC17 strains, the mycelial growth of R. solani was inhibited by 78 % and for the strain BC45 the value amounted 46 %. In the pot bioassay the number of infested plants growing in the soil inoculated with P. agglomerans and the pathogen was lower when compared with the pots containing R solani. A higher reduction of infested plants, amounting 23 %, was obtained for the strain BC17. Both strains had the ability to produce IAA - a plant hormone of the auxin class, in the presence of tryptophan and its absence in the medium. The highest concentration of IAA was recorded after 7 days of culturing in the supernatant obtained from the media containing 2000 μg/cm3 of tryptophan. For the strain BC17 the concentration of IAA marked in the post - culturing liquid amounted 71.57 μg/cm3, and for the BC45 strain it amounted over 80 μg/cm3. Obtained results prove that P. agglomerans may be used in the biological protection against phytopatogenic strains of R. solani.
Wireless Light-Weight IEC 61850 Based Loss of Mains Protection for Smart Grid
Authors: Mekkanen Mike , Kauhaniemi Kimmo 
Published: July 2018

Abstract
This paper presents a novel Loss of Mains (LoM) protection method based on IEC 61850 Manufacturing Messages Specification (MMS) protocol over wireless Global System for Mobile Communication (GSM) based access point name (APN) mechanism. LoM or anti islanding protection is a key requirement in modern power distribution grids where there is significant amount of distributed energy resources (DER). The future Smart Grids are based on extensive communication capabilities and thus the communication based LoM approaches will also become dominant. The IEC 61850 standard based systems are gaining ground in the substation communication, and therefore, it is natural to expand this technology deeper into the distribution network. Using this standard for LoM protection, also enables some advanced approaches utilizing large variety of information available in the Smart Grid. There is a specific part of the standard, IEC 61850-7-420, which defines logical nodes (LNs) suitable for this purpose; but, there are no available devices applying this part of the standard yet. In this research, a light-weight implementation of IEDs (Intelligent Electronic Devices) is developed using a low-cost open microcontroller platform, Beagle Bone, and an open source software. Using this platform, a wireless LoM solution based on IEC 61850 MMS protocol has been developed and demonstrated. This paper introduces object modelling according to IEC 61850-7-420 defined LNs and an implementation applying direct client server MMS based communication between lightweight IEDs. The performance of the wireless application using the developed platform is demonstrated by measuring the message latencies.
In this paper, a novel LoM protection concept is proposed based on the standardized communication solution brought by IEC 61850 and specific LNs for DERs defined in IEC 61850-7-420. A light-weight implementation of an IEC 61850 based IED is developed in order to reduce large overhead information and complexity of the standard. In addition to LoM function, the developed solution has the ability to monitor DERs status. The available monitoring information can be shared among various distribution management systems (DMS), enabling distributed decision approach for various purposes.
Where Do Accelerators Fit in the Venture Creation Pipeline? Different Values Brought by Different Types of Accelerators
Authors: Yang Shu , Kher Romi , Lyons Thomas S. 
Published: July 2018

AbstractDespite the emergence of startup accelerators as venture development organizations (VDOs) to high-growth firms, research has yet to identify where these accelerators fit into the venture development ecosystem. By clarifying and reviewing three different subsystems in the entrepreneurial ecosystem, our paper proposes that as an extension of the current incubation mechanism, accelerators contribute to the entrepreneurial ecosystem by transforming entrepreneurs and their ventures at early stages. Drawing upon the Pipeline model (Lichtenstein, G. A., and T. S. Lyons. 2006. “Managing the community's pipeline of entrepreneurs and enterprises: A new way of thinking about business assets.”Economic Development Quarterly20 (4): 377–386.), we first plot where the accelerator model fits in the broader entrepreneurship ecosystem, and then demonstrate how different types of accelerators help participating entrepreneurs and their ventures progress along the venture development pipeline. Our theoretical approach contributes to both the entrepreneurship ecosystem and the accelerator literature and provides a practical map for both policymakers and early-stage entrepreneurs to manage and utilize their entrepreneurship ecosystem more effectively.
