Dolichoectasia of the Anterior Cerebral Circulation: a Case Report

We report a case of dolichoectasia of the anterior cerebral circulation, first suspected on computed tomography (CT) to be arteriovenous malformation (AVM) or dural arteriovenous fistula (DAVF), and was confirmed to be dolichoectasia using digital subtraction angiogram (DSA). This case highlights the importance of considering dolichoectasia as a differential diagnosis, since its differentiation from AVM or DAVF has important clinical implications in terms of subsequent treatment options. The case also highlights the important role of DSA in differentiating AVM or DAVF from dolichoectasia.
Is Consumer Experience the Next Best Thing? Reflections from a systematic review and research agenda proposition

Literature recognizes consumer experience as an important construct to understand consumer behavior as well as the dominant basis for market differentiation. There is a growing body of knowledge on consumer experience, but little is known about the characteristics of its scientific production. Considering this, we performed a systematic review in order to provide an overview on consumer experience developments. We selected 414 articles for the final analysis and categorized them according to demographic, institutional and methodological criteria. Results indicated the predominance of empirical work, quantitative methods and organizational perspective. We concluded consumption experience is at the top of marketing agenda on research and practice, but it is still an incipient construct, lacking theoretical discussions, especially concerning its conceptualization, and the development of consumer perspective, which will lead consumer experience to the comprehension of consumption phenomena on its totality and complexity.
Map Matching for Urban High-Sampling-Frequency GPS Trajectories

As a fundamental component of trajectory processing and analysis, trajectory map-matching can be used for urban traffic management and tourism route planning, among other applications. While there are many trajectory map-matching methods, urban high-sampling-frequency GPS trajectory data still depend on simple geometric matching methods, which can lead to mismatches when there are multiple trajectory points near one intersection. Therefore, this study proposed a novel segmented trajectory matching method in which trajectory points were separated into intersection and non-intersection trajectory points. Matching rules and processing methods dedicated to intersection trajectory points were developed, while a classic “Look-Ahead” matching method was applied to non-intersection trajectory points, thereby implementing map matching of the whole trajectory. Then, a comparative analysis between the proposed method and two other new related methods was conducted on trajectories with multiple sampling frequencies. The results indicate that the proposed method is not only competent for intersection matching with high-frequency trajectory data but also superior to two other methods in both matching efficiency and accuracy.
Oceanic heat transport into the Arctic under high and low CO 2 forcing

Enhanced ocean heat transport into the Arctic is linked to stronger future Arctic warming and polar amplification. To quantify the impact of ocean heat transport on Arctic climate, it is imperative to understand how its magnitude and the associated mechanisms change in other climate states. This paper therefore assesses the ocean heat transport into the Arctic at 70◦N for climates forced with a broad range of carbon dioxide concentration levels, ranging from one-fourth to four times modern values. We focused on ocean heat transports through the Arctic entrances (Bering Strait, Canadian Archipelago, and Nordic Seas) and identified relative contributions of volume and temperature to these changes. The results show that ocean heat transport differences across the five climate states are dominated by heat transport changes in the Nordic Seas, although in the warmest climate state heat transport through the Bering Strait plays an almost equally important role. This is primarily caused by changes in horizontal currents owing to anomalous wind responses and to differential advection of thermal anomalies. Changes in sea ice cover play a prominent role by modulating the surface heat fluxes and the impact of wind stresses on ocean currents. The Atlantic meridional overturning circulation and its associated heat transport play a more modest role in the ocean heat transport into the Arctic. The net effect of these changes is that the poleward ocean heat transport at 70◦N strongly increases from the coldest climate to the warmest climate state.
Improve of Harmony Search by Scramble Mutation for Global Optimizations Problems

Harmony search (HS) is a new meta-heuristic optimization method imitating the music improvisation process where musicians improvise their instruments pitches searching for a perfect state of harmony. The usage of HS has become a common thing for a variety of numerical and real-world problems. It has several advantages over other meta-heuristics. It considers all existing vectors to generate a new vector. It imposes fewer mathematical requirements. The main disadvantage of HS encompasses its tendency to converge prematurely, which in essence leads to lose diversity during the search. In this study, a new variant of HS, called Scramble Mutation Harmony Search (SMHS), is proposed in this work where concepts from Genetic Algorithm (GA) process are borrowed to enhance the performance of HS. The Scramble Mutation is original step of GA, and is popular with permutation representations. In this, from the entire chromosome, a subset of genes is chosen and their values are scrambled or shuffled randomly. The performance of the SMHS is evaluated and compared with HS (a recently developed variation of HS that is, DLHS, and MHS). The experiments conducted show that the SMHS generally outperformed the other approaches when applied to ten benchmark problems. The effect of the SMHS parameters is analysed. Finally, the results show that cellular approaches seem to be an efficient alternative for optimization problems.

Influence of latent infection by apple stem grooving virus (ASGV) on the development of young apple trees cv. Florina - preliminary research investigation

Article presents the results of a survey of some morphological and physiological indicators of young apple trees infected with Apple Stem Grooving Virus, (ASGV). Trees were symptomless for viral infection during the period of apple orchard monitoring (2013 – 2014). Samples of young leaves collected from 23 apple trees cv. Florina were tested using enzyme linked immunosorbent assay (ELISA). Trees with extinction values at least three times greater than the negative control were defined as infected. Trunk diameter of infected trees increased statistically significant compared to control. Spectral reflectance characteristics obtained by remote sensing method of leaf reflectance confirmed the presence of two groups of infected trees against the group of healthy (control) trees. With calculated vegetation indices were corroborated the changes in some indicators characterizing the evolution and habitus of trees. Good correlation between vegetation indices and extinction values obtained by ELISA was found. Results of spectral analyses indicate that the leaf spectral reflectance is a reliable tool for early detection of stress in young apple trees.
EXPRESSION OF PROTEIN CD73/CD90/CD105/CD34/CD45/CD11b/CD19/HLA-DR ON STEM CELLS FROM HUMAN FAT TISSUE, USING CYTOMETRY FLOW

AbstrakSel punca merupakan sel yang dapat membelah dan berdiferensiasi menjadi sel jenis lainnya. Sel punca asal jaringan lemak potensial dikembangkan sebagai salah satu alternatif sel punca yang bersumber dari limbah sedot lemak manusia. Sel punca asal jaringan lemak akan mengekspresikan protein spesifik penanda permukaan CD73, CD90, CD105 dalam persentase yang tinggi dan CD34/CD45/CD11b/CD19/HLA-DR dalam persentase yang rendah. Studi ini bertujuan untuk memanfaatkan limbah sedot lemak manusia dengan melakukan isolasi sel punca asal jaringan lemak dan menguji protein penanda permukaan spesifik sel punca. Beberapa tahapan dalam studi ini adalah isolasi stromal vascular fraction (SVF) dan kultur sel punca asal jaringan lemak manusia, population doubling time (PDT) serta analisis protein penanda permukaan CD7Ee3, CD90, CD105, dan CD34/CD45/CD11b/CD19/HLA-DR pada pasase ke-1 dari 3 donor. Hasil dari studi ini menunjukkan bahwa sel dari jaringan lemak berhasil dikultur dengan durasi pembelahan sel adalah 3,3 hari. Sel mengekspresikan CD73 (99,79%), CD90 (94,17%), CD105 (48,75%), dan CD34/CD45/CD11b/CD19/HLA-DR (kurang dari 2%). Ekspresi CD105 yang rendah dari ketiga donor diduga berkaitan dengan tingkatan pasase sel yang digunakan. Berdasarkan hasil tersebut dapat disimpulkan bahwa sel punca asal jaringan lemak pasase ke-1 telah mengekspresikan ketiga marker protein penanda permukaan sel punca, yaitu CD73, CD90 dan CD105.Abstract Stem cells are cells that can divide into other different types of similar cells. Stem cells from fat tissue potential have been developed as an alternative stem cell from human liposuction. Stem cells from fat tissue will express high protein-specific markers on CD73, CD90, CD105 and CD34/CD45/CD11b/CD19/HLA-DR in a low percentage. This study aims to utilize human liposuction waste by isolating stem cells from fat tissue and testing protein-specific stem cell surface markers. Some stages in this study are isolation of stromal vascular fraction (SVF) and stem cell culture from human fat tissue, population doubling time (PDT) and protein analysis of surface markers CD73, CD90, CD105, and CD34/CD45/CD11b/CD19/HLA-DR on the 1st passage of 3 donors. The results of this study showed that cells from fat tissue were successfully cultured with cell division duration of 3.3 days. Cells expressed CD73 (99.79%), CD90 (94.17%), CD105 (48.75%), and CD34/CD45/CD11b/CD19/HLA-DR (less than 2%). The low expression of CD105 from all three donors is thought to be related to the level of cell passage used. Based on these results, it can be concluded that the stem cells from first passage fat tissue have expressed the three protein markers of stem cell surface markers, namely CD73, CD90 and CD105.
Coliforms Contamination in Raw Milk and Some Dairy Products with Special Reference to Comparative Identification of Enterobacter spp.

The current study was undertaken to examine 200 sample of raw milk and some dairy products (Kariesh cheese, plain yoghurt, milk powder and infant formula) for contamination with Coliform group especially Enterobacter spp. Coliforms were detected in; 42/50 (84%) raw milk samples from farmers' houses, 25/30 (83.33%) kariesh cheese samples and 23/30 (76.67%) plain yoghurt samples, however, they could not be detected in any of raw milk samples from dairy shops, milk powder and infant formula samples. The mean values of coliforms in the examined samples were 2.80x106 ±0.73x105, 2.30×106 ±0.75×104 and 1.08×106 ± 1.50×104 cfu /ml or gm in raw milk from farmers' houses, kariesh cheese and plain yoghurt samples, respectively. The biochemically identified coliforms were E. aerogenes, E. agglomerans, E. cloacae, C. diversus, C. freundii, E.coli, K. oxytoca and K. pneumonia with respective percentages of; 1.19, 1.19, 2.38, 25, 15.48, 26.19, 13.09 and 15.48, in raw milk from farmers' houses, 6, 0, 2, 28, 10, 22, 0, and 32 in kariesh cheese, 0, 0, 2.12, 23.91, 0, 36.96, 26.09, 10.87 in plain yoghurt. Comparative identification of isolated Enterobacter spp.by standard biochemical methods and Matrix Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry revealed that the total conformity of identification of Enterobacter strains between standard biochemical technique and MALDI-TOF MS technique was 66.6%, where, it ranged from 50% to 100 for E. aerogenes and E. cloaca, respectively. However, the only identified E. agglomerans isolatesfrom raw milk could not be confirmed by MALDI-TOF MS technique. It has been shown through these results that the presence of coliform and Enterobacter bacteria is an evidence of the lack of health requirements and thermal treatments of raw milk and some of its products (kariesh cheese and yoghurt).
Evaluation of Leukocyte Mobilization and Platelet Aggregatory Effects of Ciprofloxacin, Lincomycin and Erythromycin in Wistar Albino Rats

This study evaluated leucocyte mobilization and platelet aggregation effects of ciprofloxacin, lincomycin and Erythromycin in Wistar albino rats. Thirty-three female Wistar albino rats weighing 130-160 g and three male Wistar albino rats weighing 188-194 g, fed commercial growers’ mash and clean tap water were used. In leukocytes assay, thirty-three adult female Wistar rats were assigned into five treatments, eleven groups of three rats per group. First three groups were treated 10 mg kg, 20 mg kg and 40 mg kg of ciprofloxacin, next three groups same doses of lincomycin, next three groups same doses of Erythromycin, the tenth group received Indomethacin 5 mg kg (reference drug), the last group 5 mg kg normal saline. Assay on platelet aggregator activity involved collection of blood samples (10 ml each, 1% EDTA, centrifuged at 3000 rpm for 10 minutes), test drugs dissolved in 1 mg/ml distilled water and Indomethacin (the reference drug). The three antibiotics significantly reduced leucocyte mobilization into the affected tissue. They all had their maximum inhibitory effects at the highest dose (40 mg kg) compared with indomethacin. Erythromycin 40 mg kg showed the highest inhibitory effect on leucocyte migration. Whereas ciprofloxacin and erythromycin had stepwise increase in absorbance from time 0 secs through to time 120 secs, lincomycin showed a sharp decrease in the absorbance at around 30 seconds followed by a continuous increase up to 120 seconds. The testing drugs prevented leukocyte mobilization also had stepwise increase in absorbance from time 0 secs through to time 120 secs in platelet aggregatory activity assay to some extent.
Marital Adjustment, Love, Personal Intimacy, Personality, Dyadic Coping and Spirituality on Marital Stability

Marital Stability is interpreted as whether a couple in a marriage remains together, instead of separating or getting divorced. It is also called as marital longevity or duration of marriage. The aim of the study is to find the relationship between different psychosocial factor (marital adjustment, love, personal intimacy personality, dyadic coping, and spirituality) and marital stability. For the purpose of sampling, thirty married couples were randomly selected using stratified random sampling. The measuring tools used were Locke-Wallace marital adjustment questionnaire (Marital adjustment), Love scale (Love), Personal assessment of intimacy in relationship (Personal intimacy), Big five inventory (personality), Dyadic coping inventory (Dyadic coping) and the daily spiritual experience scale (Spirituality). Six null hypotheses were raised and tested using descriptive and inferential statistics (Percentage, mean, standard deviation and correlation). The research finding shows that there is a significant negative correlation between sexual intimacy Original Research Article Priyadharshini and Gopalan; AJARR, 7(4): 1-16, 2019; Article no.AJARR. 53298 2 and marital stability(r= -.44 and p<.01). All other variables (Marital adjustment, love, personal intimacy, personality, dyadic coping and spirituality) are not shown to be contributing to marital stability.
Porting tree-based hash table compression to GPGPU model checking

The GPU-based model checker GPUexplore uses a lockless hash table for the shared store of visited states in the model checking process. However, as GPU memory size is relatively limited and is now the bottleneck, we have implemented a stand-alone GPU version of an existent compression algorithm that uses this shared hash table and optimised this GPU version.
Polioencephalomalacia Caused by Thiamine Deficiency in Sheep of Basrah Province, Iraq.

Polioencephalomalacia caused by thiamine deficiency in sheep of Barash province have been diagnosed. This current research was conducted on 44 local sheep breeds 1-3 years old and of both sexes reared in Basrah province. Ten clinically normal local sheep breeds were selected as controls. Diseased animals show various clinical manifestations, Such as Anorexia and head pressing, Muscular tremors. Moreover, diseased sheep show signs of opisthotonus and nystagmus, incoordination and ataxia, Furthermore, 41% of the diseased sheep show circling with lateral deviation of the head, recumbency and inability to stand. However, 18.1% of the diseased sheep exhibit blindness. Moreover, significant increase was detected in respiratory and heart rate of diseased animals in comparison with controls, but ruminal motility was decreased significantly in affected animals compared to controls. Additionally, considerable changes were detected in biochemical parameters of affected sheep in comparison with controls. The results of cross pathological features and histopathological examination of dying or slaughtered sheep show pale discoloration of the dorsal cerebral cortex, especially the occipital lobes, which might indicate a necrosis. However, gross lesions might also represent flattening of cerebral gyri, hemorrhages, necrosis to cavitations in the gray matter of the occipital and temporal regions. Further, histopathological examinations revealed gliosis as well to vacuolative changes of some neurons, Moreover, sections of the white matter of brain showed also gliosis with wallerian degeneration of some neuronal axons, Furthermore, sections were also indicated a severe vaculation of neuronal cell body and central chromatolysis of some neurons.
European Next Reusable Ariane ( ENTRAIN ) : A Multidisciplinary Study on a VTVL and a VTHL Booster Stage

The recent success of the emerging private space companies SpaceX and Blue Origin in landing, recovering and relaunching reusable first stages have demonstrated the possibility of building reliable and low-cost reusable first stages. Thus, the importance for assessing whether such a reusable launch vehicle (RLV) could be designed and built in Europe has increased. Due to this renewed interest in RLVs, the German Aerospace Center (DLR) has initiated a study on reusable first stages named ENTRAIN (European Next Reusable Ariane). Within this study two return methods, respectively vertical take-off, vertical landing (VTVL) and vertical take-off, horizontal landing (VTHL) with winged stages, are investigated. The goal is to assess the impact of the return method on the launcher and to conduct a preliminary design of a possible future European RLV. In the first part of the study, which ended in 2018, a broad range of possible launcher designs considering different propellant combinations, engine cycles and staging velocities were investigated and compared. By the end of this part, the most promising VTVL stage such as the most promising VTHL stage were selected to be investigated in more detail. Those two concepts were subjected to a preliminary system design and performance estimation, coupled with an aerodynamic and aerothermodynamic investigation of the re-entry loads and their impact on the structure. Furthermore, analyses of the dynamic behavior of descending RLV stages are considered. With the know-how gained within this study, the design of both launchers shall be enhanced to a level that brings it closer to a viable future reusable European launcher.
Risk factors associated with retail meat vendors in Lubumbashi, Democratic Republic of Congo

Food safety risk factors associated with retail meat sales in Lubumbashi, Congo D.R. , was assessed in 2013. The study involved 168 meat vendors. The methods used were an interview and direct observation. Females represented 55.9%, and males represented 44% of the study respondents. Their age ranged from 18 to 40 years (92.8%). Sixty percent had obtained a primary level of education, 38% a secondary level, and only 1.1% completed the university level of education. Sixty-nine percent had fixed activities, and 30.9% were mobiles. None had a training certificate in food safety or hygiene practices. Overall, the poor level of knowledge/attitude and practices was associated with low level of education and the age of the vendors ( 0.05). Attitude, practices, and lack of food safety knowledge in meat handling, improper slaughtering processes, poor environmental and personal hygiene, inadequate storage of food and lack of potable water were identified as major risk factors which may contribute to various contamination of meat sold at retail outlets in Lubumbashi. Key words: Retail meat vendors, attitudes, practices, knowledge, food safety, Lubumbashi, Congo D.R.
Simulation of Two-Phase Flow and Heat Transfer in a Channel and around a Tube by Lattice-Boltzmann Method

Determination of multiphase flow dynamics and thermal behavior of two-phase flow in a channel are of importance. The small-scale surface tension effect and related simulation efficiency, precision, and stability, have caused mesoscopic Lattice Boltzmann method broadening application. In the current study, the thermalhydraulic behavior of subcooled falling flow in a vertical channel and around a single horizontal tube is simulated by using Lee method and Phase-Filed model, and thermal Passive Scalar model. The modified curved boundary conditions and two different boundary conditions for side boundaries are investigated. The density ratio is 20 and other property’s ratios of water are applied, and the outside diameter of tube is 28.9mm. The flow, temperature, and pressure fields are presented and detailed understanding about the movement of the three-phase contact line, circulating flow and local and average Nusselt number are determined. The film thickness, thermal boundary layer variation by the film thickness, Reynold number effect on Nusselt number and mass conservation are investigated as verification. The results have shown good consistency and high effectiveness in the simulation of multiphase gas-liquid flows in the presence of a circular obstacle, and for viscosity and thermal diffusivity ratios of water.
