The Effect of Performance and Services Quality on Satisfaction of Internal and External Customers Based on Total Quality Management Social Services in Siak District

The success of the nation's development in Indonesia is inseparable from the role and function of government organizations that carry out government duties because of the success of government organizations in achieving goals that strongly support the achievement of national development goals. In achieving maximum performance a person must be active in completing all his tasks. Also, this action can prevent the occurrence of employee performance phenomena that are not disciplined, giving rise to unsatisfactory actions in providing services to the public. According to external (community) customers/visitors, some of them complained and mentioned that it was not uncommon to find employee phenomena in providing non-optimal services such as employees who were late or lacking in time discipline taken from attendance data. social service offices, employees who are not available when needed under the pretext of attending meetings or other service events. This research used quantitative approach with associative research type that goal to find influence among some variables. The population in this study were employees and visitors to the Siak District Social Service Office, with a total sample of 179 respondents including 25 internal people and 154 external people (community). The sample used in this study was based on Slovin Formula with a tolerance level of 5%. Sampling uses a simple random sampling technique. Data collection tools used are questionnaires/questionnaires arranged according to research variables using a Likert scale, where each question has five alternative answers. The results of the study show that there are effects that are owned by the Performance variable on the internal and external customer satisfaction variables partially is 73.8% internal while the external value is 34.9%. And for the strengh of the influence owned by the Service Quality variable on the internal and external customer satisfaction variables partially is 32.8% internal while the external value is 21.1%.
Investigating the flow behavior of dilute aloe vera biopolymer solutions in microchannel

Abstract The aim of the present work is to investigate the flow enhancement performance of an organic polymeric additive extracted from Aloe Vera in a specially designed microchannel simulating the real flow in the human artery. The additive rheological and flow enhancement properties were tested using a rheometer and an open-loop microfluidics flow system, respectively. The additive concentrations and solutions flow rates were the main investigated variables in the present work. The experimental results confirmed the flow enhancement effect of the new organic additive with a maximum flow enhancement up to 94% with the addition of 100 ppm of additives at 400 mbar pressure. The flow enhancement performance in heart artery-like microchannel was lower than in the straight channel due to the complexity of the design that can result in a high back pressure.
Dam Breach Size Comparison for Flood Simulations. A HEC-RAS Based, GIS Approach for Drăcșani Lake, Sitna River, Romania

Floods are the most destructive natural phenomenon, by the total number of casualties, and value of property damage, compared to any other type of natural disaster. However, some of the most destructive flash floods are related to dam breaches or complete collapses, that release the large amounts of water, affecting inhabited areas. Worldwide, numerous dams have almost reached or surpassed the estimated construction life span, and pose an increasing risk to structure stability. Considering their continuous degrading state, increasing rainfall aggressiveness, due to climatic changes, technical error, or even human error, there are numerous, potential causes, for which dams could develop breaches and completely fail. This study aims to portray a comparative perspective of flood impact, with real-life consequences, measured by quantifiable parameters, generated from computer simulations of different breach sizes. These parameters include the total flooded surface, water velocity, maximum water depth, number of affected buildings, etc. The analysis was undergone by means of HEC-RAS based 2D hydraulic modeling and GIS, depending on high-accuracy Lidar terrain data and historical hydrological data. As a case study, Drăcșani Lake with the associated Sulița earthfill embankment dam was chosen, being one of the largest and oldest artificial lakes in Romania.
Scalable and efficient authentication scheme for secure smart grid communication

Smart grids represent the latest trend that has disrupted the energy supplier sector. They are in the form of smart meters that automatically communicate power consumption data to the power grid operator. In fact, the smart-grid technology is a great solution for energy suppliers and their end customers, enabling them to perform more frequent measurements of energy, monitor their consumption and thus control the amount of their energy bills. Although the smart-grid technology brings significant gains in performance and economy to its users. However, this advanced technology immediately raises different types of attacks that can adversely affect the operation of smart grids by falsifying electricity consumption data transmitted between smart meters and the power distribution server and therefore through the generation of incorrect energy billing invoices. The reflection carried out in the proposed approach is part of this problem. It is particularly concerned with realising a new privacy-protected authenticated key agreement scheme for secure communication between smart meters and energy providers. The conducted experiments show that the proposed authentication scheme exceeds its competitors in terms of calculation costs and resistance to various types of attacks.
Association between polymorphic markers human leucocyte antigen-G and tumour necrosis factor alpha and susceptibility to recurrent miscarriages among Bulgarian women

Objective: To analyze the role of 14 base pair (bp) insertion (ins)/deletion (del) and tumour necrosis factor alpha (TNF-α) G/A polymorphisms as risk factors for spontaneous miscarriage in patients with two or more unsuccessful pregnancies and a group of control women with at least two normal live births. Materials and Methods: To investigate the role of these mutations, 50 patients with two or more idiopathic recurrent miscarriages and 50 normal fertile women were tested for the presence of human leucocyte antigen-G (HLA-G) 14 bp ins/del and TNF-α -308 G/A variants. The frequencies of the studied polymorphisms were compared between the two groups. Results: Individuals with a history of miscarriages had a significantly higher prevalence of 14 bp insertion alleles compared with control patients (p=0.04). There was also a two times higher relative risk for miscarriage among carriers of this variant. No statistical difference in allele frequencies of the TNF-α -308 G/A polymorphism was established between controls and study patients (p=0.78). Conclusion: The 14 bp ins HLA-G variant could be associated with a higher risk for unsuccessful pregnancy according to the results from the study. There is no association between the studied TNF-α -308 GA polymorphism and rate of spontaneous abortions.
Improving Animal Health on Organic Dairy Farms: Stakeholder Views on Policy Options

Although ensuring good animal health is a stated aim of organic livestock farming and an important reason why consumers purchase organic products, the health states actually achieved are comparable to those in conventional farming. Unfortunately, there have been no studies to date that have assessed stakeholder views on different policy options for improving animal health on organic dairy farms. To address this deficit, stakeholder consultations were conducted in four European countries, involving 39 supply-chain stakeholders (farmers, advisors, veterinarians, inspectors, processors, and retailers). Stakeholders were encouraged to discuss different ways, including policy change, of improving organic health states. Acknowledging the need for further health improvements in organic dairy herds, stakeholders generally favoured establishing outcome-oriented animal health requirements as a way of achieving this. However, as a result of differing priorities for animal health improvement, there was disagreement on questions such as: who should be responsible for assessing animal health status on organic farms; and how to define and implement minimum health requirements. The results of the study suggest that future research must fully explore the opportunities and risks of different policy options and also suggest ways to overcome the divergence of stakeholders’ interests in public debates.
Influence du polymorphisme du promoteur des sous-types du VIH-1 sur la dynamique de la réplication virale in vivo

Le promoteur viral module la transcription et par consequent la replication virale. Le promoteur du VIH-1 est polymorphe pour une variete de sites de fixation de facteurs de transcription, toutefois l'impact de ce polymorphisme sur la replication virale in vivo n'est pas elucide. Nous avons construit des virus chimeres isogeniques portant le promoteur minimal des sous-types B, C, et E du VIH-1 dans le genome du VISmac239. Dans quatre macaques rhesus co-infectes avec les trois chimeres, une discordance entre les genotypes des virus associes aux rPBMCs et des virions du serum est observee lors de la primo-infection. Un changement dans le genotype viral est egalement visible entre la primo-infection et la phase asymptomatique. Nos resultats montrent que le polymorphisme du promoteur des sous-types du VIH-1 constitue un determinant majeur pour la replication et la dissemination virale, et que la viremie en primo-infection est majoritairement due a la replication virale dans l'intestin.
Sustaining Productivity in Aonla Based Hortipasture System through In-Situ Soil Moisture Conservation in Semi-Arid Region of India

Introduction Globally land degradation affects about one sixth of the world population. In India, about 120 m ha area is affected with different kinds of land degradation. Under such situation, horti-pasture system provides best and economic alternative in conjunction with in-situ soil moisture conservation in general and semi-arid tropics in particular. India supports 55% buffaloes, 16% cattle, 20 % goats and about 4% sheep with deficit of 35% green fodder (525.51 mt), 10% dry fodder (453.28 mt) and 44% feed (28.4 mt) (IGFRI Vision, 2050). The per capita/day availability of fruits is 85 g as compared to average requirement of 120 g (CISH Vision, 2050). The above target could be achieved through adopting horti-pasture system in degraded land in combination of in-situ moisture conservation practices with suitable fruit and forage specie. Aonla (Emblica officinalis Gaertn.) is an important fruit crop and grown commercially because of its high economic return, therapeutic and neutraceutical value and its suitability for marginal lands (Kumar and Chaubey, 2008). Stylosanthes seabrana is perennial legume having good persistency under semi-arid condition and well adapted to tropical and subtropical environments with summer-dominant rainfall between 500-1,000 mm and very drought tolerant (Maass and Mannetje, 2002). Cenchrus ciliaris is also an important pasture easy to establish and provides comparatively high value forage suitable for direct feeding as well as quality hay (Trivedi, 2010).

A highly selective ATP-dependent potassium channel opener mimics ischaemic preconditioning protection in isolated human atrium

The K-ATP channel has been implicated in the mechanism of ischaemic preconditioning. We examined the effects of EMS 191095, a highly selective K-ATP channel opener, either alone or with glibenclamide (K-ATP channel blocker), on human atrium. Isolated human atrial trabecula superfused with oxygenated Tyrode's solution and paced at I Hz underwent one of four protocols prior to 90 min hypoxic substrate-free perfusion at 3 Hz (simulated ischaemia), followed by 120 min of reoxygenation with substrate at I Hz (reoxygenation). Preconditioning (PC) consisted of 3 min simulated ischaemia and 7 min reoxygenation. The experimental endpoint was recovery of contractile function, presented as percentage of baseline function. EMS (45.8% +/- 4.4) and PC (50.5% +/- 3.6) produced similar functional recoveries following 120 min reperfusion; significantly different to controls (20.8% +/- 3.5, p<0.05, ANOVA). Glibenclamide abolished the EMS protection (20.8% +/- 4.2). This results suggest that ischaemic preconditioning in humans may occur via a K-ATP channel opening effect.
Temperature and Estrogen Alter Predator–Prey Interactions between Fish Species

Synopsis A variety of environmental estrogens are commonly detected in human-impacted waterways. Although much is known about the effects of these environmental estrogens on the reproductive physiology and behavior of individuals within species, comparatively less is known about how these compounds alter the outcomes of interactions between species. Furthermore, few studies have considered how the effects of contaminants are modulated by natural variation in abiotic factors, such as temperature. To help fill this knowledge gap, we conducted a factorial experiment to examine the independent and combined effects of estrone (E1) and temperature on the outcome of predator–prey interactions between two common North American freshwater fishes, fathead minnows (Pimephales promelas) and bluegill sunfish (Lepomis macrochirus). Larval fathead minnows and adult sunfish were exposed to either a low (mean±standard deviation, 90.1 ± 18 ng/L; n = 16) or high (414 ± 147 ng/L; n = 15) concentration of E1 or to a solvent control for 30 days at one of four natural seasonal temperatures (15°C, 18°C, 21°C, and 24°C) before predation trials were performed. Exposure to E1 was associated with a significant increase in larval predation mortality that was independent of temperature. Across all temperature treatments, approximately 74% of control minnows survived; this survivorship significantly exceeded that of minnows exposed to either concentration of E1 (49% and 53% for minnows exposed to the low and high concentrations, respectively). However, exposure to E1 also impaired the prey-capture success of sunfish, partially mitigating predation pressure on exposed minnows. Overall prey-capture success by sunfish showed an inverted U-shaped distribution with temperature, with maximal prey consumption occurring at 21°C. This study illustrates the vulnerability of organismal interactions to estrogenic pollutants and highlights the need to include food web interactions in assessments of risk.
Simulation and Analysis of Polyetheretherketone Implants for Diaphysis Femur Fracture

 Abstract — In the present work, reverse engineering approach has been used to create a 3D model of a fractured femur diaphysis bone using the computed tomography (CT) scan data. Thereafter, a counter fit fixation plate of polyetheretherketone (PEEK) composite has been designed and analyzed considering static physiological loading conditions. Static stress distribution and deformation analysis of the plate have been performed. From the analysis, it has been found that the stresses and deformation developed are quite low. This implies that these designed fixation plates will be able to provide stable fixation and thus resulting in improved fracture union.
Learning Data Representation and Emotion Assessment from Physiological Data

Aiming a deeper understanding of human emotional states, we explore deep learning techniques for the analysis of physiological data. In this work, raw two-channel pre-frontal electroencephalography and photoplethysmography signals of 25 subjects were collected using EMOTAI’s headband while watching commercials. Taking as input the raw data, convolutional neural networks were used to learn data representations and classify the acquired signals according to the Positive and Negative Affect Schedule. This approach achieved promising results, with average F1-scores of 76.6% for Positive Affect and 83.3% for Negative Affect. Interpretation of the learned data representation was attempted by computing correlation values between features extracted from the raw inputs and the final classification. The features with the most significant correlations were the alpha band power, and the asymmetry and phase synchronization indexes. The extracted features seem to match the ones learnt by the neural network, hence endorsing their validity for emotional studies.
Contribution of "omics" approaches to sustainable herbivore production.

The molecular mechanisms underlying biological processes are governed by the expression of many genes. Methods to study these complex processes have known tremendous technological advances over the past few years. Whereas in the past, molecular biology targeted a few genes chosen for their biological function, today, genomics, proteomics and metabolomics allow studying simultaneously a large number of genes, proteins or metabolites, irrespective of their biological function. These new technologies will help improve our understanding of the biology of herbivores in a context of sustainable production. This short review presents some examples showing how “omics” may contribute to the improvement of production efficiency based, for instance, on the detection of markers of exposure to mycotoxins or on the improved metabolic and physiological efficiency of herbivores (partitioning of nutrients between tissues and organs, muscle differentiation for meat production, nutritional regulation of the expression of genes). “Omic” approaches can also contribute to the other pillars of sustainability: animal well-being (by revealing stress markers), protection of the environment (by studying nitrogen excretion from the animals), and product quality (by analysing the fatty acid composition of products and finding biomarkers of meat tenderness, and of milk and meat flavour).
Fine, Reversible and Broadband Tuning of the Group Velocity Dispersion of Tapered Silica Fibers in a Thermo-Optic Polymer Matrix

The development of tapered optical fibers embedded in a thermo-optic polymer matrix with reversibly tailored group velocity dispersion is hereby presented. Dispersion measurements for these tapered fibers were performed using white light spectral interferometry. The tapered fibers exhibit reversible thermo-optic group velocity dispersion tuning in both the normal and the anomalous regime in a broad spectral window extending from the E-band to the L-band of the telecommunication laser bandwidth. Group delay dispersion can be controlled thermo-optically within tuning ranges of up to −2230 fs2 in the anomalous and 2090 fs2 in the normal dispersion regime for single tapered fibers. Connecting a few of these polymer-embedded tapered fibers together offers even wider delay ranges that can be reversibly controlled. Thus, the polymer embedded tapers can be used as a versatile and modular dispersion management toolbox with the advantage of seamless integration with standard fiber optic systems. Such a dispersion management toolbox can be of use in the development of cavities for ultrafast fiber lasers and in other applications requiring fine and reversible dispersion control.
Development of a method to characterise the expression profile of electrogenic transmembrane proteins in excitable cells

Computational and mathematical models have become increasingly important and have contributed to significant advances in our understanding of complex biological systems. We developed a mathematical model to characterise the expression profile of transmembrane electrogenic proteins of excitable cells. The cell of interest is the myometrium smooth muscle cell, which is the principal unit of electrical activity in the uterus. These cells remain quiescent throughout most of gestation, whereas just prior to and during labour they are able to generate spontaneous action potentials. A more detailed and comprehensive characterisation of these cells, in comparison to previous models, would furnish an appropriate tool for the development of therapeutics to manage preterm birth and other perinatal problems associated with uterine contractility, such as postpartum haemorrhage. The "conductome" can be defined as the totality of ion channels and ion transporters expressed by an electrically active cell, i.e., a list specifying the cell surface density and oligomeric composition of each of these species. Gene expression techniques can accurately survey the complete set of all mRNA species encoding electrogenic proteins (e.g., subunits of channels). The conductome is constrained by this transcriptome, but the link between the two is complicated by the facts that (i) presence of an mRNA species does not necessarily imply the presence at the transmembrane proteomics level; and (ii) subunits can combine in various ways to give rise to conducting channels with different properties. Every individual potential oligomeric channel complex was represented as a mathematical model on the basis of biophysical data taken from the literature; these data were obtained mainly using heterologous expression systems. We investigate the possibility of combining the behavioural information of the action potential with the detailed molecular data of the transcriptome. The general problem is that electrical behaviour does not necessarily lead to a unique solution. The question addressed here is to what extent the additional information provided by transcriptomics helps to constrain the solution space. We develop and apply a method to characterise the functional redundancy of electrically active cells. We use mRNA sequencing to determine which electrogenic species the cell is capable of expressing, combined with a least-squares parameter estimation procedure to determine the conductome from electrophysiological data. Moreover, we estimate the parameters associated with the gating kinetics from published data, so that the only remaining free parameters are the surface densities of the species on the list defined by the transcriptomics analysis.
Toxicological studies of antioxidants, butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA)

식품에 항 산화제로 첨가시키는 BHT와 BHA의 독성에 대해 고찰하였다. BHT와 BHA는 실험동물에서 간, 폐, 신장, 순환계, 생식계, 등에 여러 영향을 주며 이러한 영향은 동물의 종류와 성에 따라 상당한 차이를 나타내고 있다. 대부분 실험에 사용된 BHT와 BHA의 양이 인체가 매일 식품으로부터 흡수할 수 있는 양보다는 훨씬 많은 양을 사용하였기 때문에 동물실험의 결과로 인체에 유독성을 직접 판단하기는 어렵고 이들의 안전성에 대해서는 보다 체계적인 연구가 앞으로 요구된다. 미량의 BHT와 BHA를 장기간 복용하였을 때 생기는 부작용에 대한 연구가 필요하며 또한 이들 항 산화제는 약물대사에 관여하는 효소의 합성내지 활성도를 증가시키는 것으로 알려져 있기 때문에 체내에서 다른 약물의 대사 및 독성에 어떤 상호 작용을 가져오는 지에 대한 면밀한 연구가 요구되고 있다. 더불어 본 논문은 현시점에서 이들 항산화제의 식품에 첨가여부를 논쟁하고자 하는 의도가 전혀 없음을 명백히 하는 바이다.
