Abstract
Endosulfan is an organochlorine insecticide that has high toxicity, persistent and bioaccumulative. Endosulfan entering the waters can cause subletal toxicity to fish. Endosulfan residues that enter the body of the fish will inhibit their reproduction, such as the formation of vitelogenin. This study aimed to determine the effect of concentration and length of time endosulfan exposure which could reduce vitelogenin gene expression in female silver sharkminnow (Osteochilus hasseltii C. V.). Complete randomized design was applied using four treatments of endosulfan concentration i.e. 0 ppb, 0.88 ppb, 1.76 ppb and 2.64 ppb, respectively. The research was conducted for four weeks with sampling frequency every two weeks. The molecular study was carried out four steps include organ preparation, RNA isolation and DNAse treatment, measurement of RNA concentration and vitelogenin gene expression and RT-PCR was used in this study. Gene expression data analyzed by One Way ANOVA to each of the response variables to know whether differences existed among treatments. The results showed that the concentration and exposure time of endosulfan had not given different result on each treatment. This was presumably because the concentration of endosulfan given had not been able to influence changes in gene expression of vitelogenin in female silver sharkminnow.

Authors: Ghani I M Md , Rahim H A 
Published: December 2019

AbstractManufacturing is one of the major sectors that contribute to the economy of Malaysia. The situation of manufacturing sales, especially rubber gloves received the attention of investors to forecast. However, the pattern of economics exposed to unexpected changes, which called outlier which occurred because of internal or external factors. Consequently, give shock to time series data. The main approach used is the hybrid of Autoregressive Moving Average (ARMA) model and Generalized Autoregressive Conditional Heteroscedasticity (GARCH) model. The effectiveness of the volatility model with the existence of outliers are measured by Monte Carlo method. Besides, to find the best ARMA-GARCH model there are four models produced from different specifications in ARMA(a,b) and GARCH(g, h) models. In this paper, we used 216 monthly price data of Standard Malaysian Rubber Grade 20 (SMR 20) in Malaysia. The validity comparison of diagnostic checking is measured on AIC, AICc, SIC and HQIC. While the forecasting performance evaluated using MSE, RMSE and MAPE. The results of the empirical analysis indicate that the ARMA(2,0)-GARCH(1,2) model is the appropriate model to forecast the price of SMR 20 that were used to the manufacturing of rubber gloves in Malaysia.

AbstractThis study examines the problem of facility location and vehicle routes determination in supply chain system periodically. The problem is determining the location and route to meet the supply of commodity to the power plant that taken from the case of an electricity company in Indonesia. In this study, the problem is called Periodic Location Routing Problem (PLRP). Periodic Location Routing Problem is a non-polynomial hard problem (NP-hard), if locations considered is increase, the computation time used is increasing exponentially. Therefore, to solve a large-scale of this problem, a local search algorithm is proposed. Local search is a very simple metaheuristic algorithm. To explore the solution space for the problem, this algorithm will use the relocation operator. The results of computational experiments from 10 instances indicate that the results of the solution have a small standard deviation with short computing time in less than 2 hours.

Published: December 2019

Abstract
The objective of this research is to reduce the process distance on storage and retrieval (S/R) by suggesting storage system of piano’s cabinets (piano’s parts) on the certain storage shelf. The object of the research is department of setting cabinet that obligated to bridge and organize cabinet’s supply from department of painting to department of assembly. Based on the planning and actual delivery of piano cabinets to department of assembly, it is found that only 33,3% deliveries were accomplished as recorded by data on April 2018. One of the causes is internal handling problem at the department of cabinet setting that takes longer time due to unorganized cabinet storage. After all data of “in-out stock” are resumed, later it will be processed by employing class-based storage method for material’s grouping. The data indicated that cabinet with material class A is dominated by top 4 requested models of piano and the comparison between initial storage system layout and the proposed one shows the difference on total distance of retrieval activities for 210 kilometers during 5 months of working. It could be concluded that the purpose of storage system could reduce the retrieval distance by 68%.

Abstract
Aviation accidents still hit the news even though the growth of technological advancement on commercial aircraft avionic systems has been impressive. Hence, one of the objectives of this study is to plot the time-based graph of commercial aviation accidents, with direct consequence from avionics instrumentations in the period of two decades, from 1996 to 2015. The second objective is to analyse two main aircraft manufacturers, Boeing and Airbus, in determining specific model of its kind that significantly involved in avionics-related instrumentation as one of the contributing factors that leads to the incidents or accidents. The third objective is to identify which avionics system that most frequently involved in aviation incidents, for both manufacturers. The final objective is to examine the main probable cause that has the highest percentage in those accidents within the said time frame. The method of collecting data is by doing comparative analysis from reliable official websites of four well-known bodies such as National Transportation Safety Board (NTSB), Federal Aviation Administration (FAA), Aviation Safety Network and Flight Safety Foundation. Results show that misfortune occurrences are directly associated with avionics within the said two decades, which mainly involved Autopilot and Flight Management System (FMS) (14% each), meanwhile the aircraft model Boeing 737 carries the highest percentage of avionics-related incidents or accidents. Nonetheless, 67% of the misfortune occurrences within the scope of study are mainly due to human error instead of technology.
Purchase price adjustment disputes in mergers and acquisitions: an intersection of different dispute resolution procedures and a war of jurisdictions
Authors: Özdem Berk Hasan , İnce İpek 
Published: December 2019

Abstract
Frequently included in mergers and acquisitions (M&A) contracts purchase price adjustment clauses allow for upward or downward adjustments to the purchase price depending on a selected metric to help the parties of a transaction to overcome the information asymmetry about financial variables caused by the time lag between signing and closing. As a complex weave of technical accounting, financial, and legal issues, regardless of how objectively and meticulously conceived and drafted, it is quite often that disruptive issues arise in connection the with these clauses. In addition to the general arbitration clause typically contained in the M&A contracts, as a common practice, parties agree to submit any dispute concerning the values reported in the financial schedules to calculate the amount of an adjustment to an independent accounting firm for an expert determination. Since most of the time contracts do not provide any particular provision as to the relation between these two mechanisms, the practice shows that neither the demarcation of the two from each other nor the interaction between them is always unproblematic. This article, after explaining the price adjustment clauses, discusses the potential problems of which the parties should be well aware and address considering the case law and different approaches.
Application of topic models to a compendium of ChIP-Seq datasets uncovers recurrent transcriptional regulatory modules
Authors: Yang Guodong , Ma Aiqun , Qin Zhaohui S , Chen Li 
Published: December 2019

Abstract

Motivation
The availability of thousands of genome-wide coupling chromatin immunoprecipitation (ChIP)-Seq datasets across hundreds of transcription factors (TFs) and cell lines provides an unprecedented opportunity to jointly analyze large-scale TF-binding in vivo, making possible the discovery of the potential interaction and cooperation among different TFs. The interacted and cooperated TFs can potentially form a transcriptional regulatory module (TRM) (e.g. co-binding TFs), which helps decipher the combinatorial regulatory mechanisms.

Results
We develop a computational method tfLDA to apply state-of-the-art topic models to multiple ChIP-Seq datasets to decipher the combinatorial binding events of multiple TFs. tfLDA is able to learn high-order combinatorial binding patterns of TFs from multiple ChIP-Seq profiles, interpret and visualize the combinatorial patterns. We apply the tfLDA to two cell lines with a rich collection of TFs and identify combinatorial binding patterns that show well-known TRMs and related TF co-binding events.
