Authors: Rohn Karl , Kummerfeld Norbert , Mischke Reinhard , Guddorf Vanessa 
Published: May 2017

SummaryObjective: Information about the influence of species variety or diseases on coagulation values in avian blood is rare. The aim of this study was to assess the influence of species on measurements of coagulation parameters in avian plasma samples using commercially available reagents and to investigate potential influences of selected diseases on clotting times. Material and methods: Prothrombin time (PT), activated partial thromboplastin time (aPTT) and thrombin time (TT) were measured in citrated plasma of healthy individuals collected from eight different wild and captive avian species applying currently commercially available reagents prepared for use in humans, which were preselected in preliminary studies. The same parameters were tested in plasma samples from birds affected by aspergillosis, atherosclerosis, neoplasia and traumata. Results: PT and aPTT showed a high interspecies variety. Irrespective of species, aPTTs were extremely long and partially exceeded the measurement range limit. Minor variations between species were seen in TT measurements. Clotting times obtained from birds affected by aspergillosis, atherosclerosis and neoplasia were not significantly different when compared to healthy birds. Plasma obtained from traumatised individuals showed significantly shorter PT and aPTT than that in healthy birds. Conclusion and clinical relevance: Differences between species must be considered in diagnostic coagulation measurements in avian blood. Regardless of the avian species, aPTT measurements on avian samples appear to be of limited value. Lower PT and aPTT values reflect coagulation activation in traumatised birds.

Bayesian Hierarchical Scale Mixtures of Log-Normal Models for Inference in Reliability with Stochastic Constraint
Authors: Kim Hea-Jung 
Published: May 2017

This paper develops Bayesian inference in reliability of a class of scale mixtures of log-normal failure time (SMLNFT) models with stochastic (or uncertain) constraint in their reliability measures. The class is comprehensive and includes existing failure time (FT) models (such as log-normal, log-Cauchy, and log-logistic FT models) as well as new models that are robust in terms of heavy-tailed FT observations. Since classical frequency approaches to reliability analysis based on the SMLNFT model with stochastic constraint are intractable, the Bayesian method is pursued utilizing a Markov chain Monte Carlo (MCMC)
sampling based approach. This paper introduces a two-stage maximum entropy (MaxEnt) prior, which elicits a priori uncertain constraint and develops Bayesian hierarchical SMLNFT model by using the prior. The paper also proposes an MCMC method for Bayesian inference in the SMLNFT model reliability and calls attention to properties of the MaxEnt prior that are useful for method development. Finally, two data sets are used to illustrate how the proposed methodology works.

Technology Focus: Natural Gas Processing and Handling (April 2017)
Authors: Wang Xiuli 
Published: May 2017

Technology Focus
Natural gas had a bullish year in 2016 as the average Henry Hub spot price jumped from USD 2.28/million Btu in January to USD 3.59/million Btu in December (+58%), “the largest percentage increase in price among energy commodities,” according to the Energy Information Administration (EIA).
According to the same source, the US market consumed 75.07 Bcf/D of gas in 2016, 0.6% more than 2015, while US consumer-grade natural-gas production was down 2.4% from 74.14 to 72.36 Bcf/D compared with 2015. Coupled with the electric-power (+4.2%) and industrial (+1.9%) sectors, this contributed to a noticeable rise in gas prices. Although the US is a net gas importer, 2016 officially marked the US as an exporter of liquefied natural gas (LNG) (by Cheniere Energy from zero in 2015 to 0.5 Bcf/D in 2016).
While gas transportation primarily by pipeline over land and LNG over water remain the most economically attractive means to transport large quantities of gas over long distances, cost-effectively monetizing stranded gas is still a challenge, especially in offshore environments.
A recent absorption-system development by ExxonMobil claims to improve the efficiency of removing water vapor from natural gas, in both on- and offshore environments, by shrinking the surface footprint by 70%, reducing the overall weight by half, and, ultimately, lowering the total cost. This technology should enable the development of some otherwise uneconomical fields.

Quantitative Viscosity, Movable Oil, and Texture Evaluation in a Heavy-Oil Carbonate Reservoir With Advanced Dielectric and Nuclear-Magnetic-Resonance Log Integration
Authors: Ali M.. , Sangani P.. , Iqbal A.. , Yepes O.. , Murray M.. 
Published: May 2017

Summary
Textural and wettability variations are two main vexing problems in carbonate reservoirs. Adding heavy oil presents an incremental challenge to the reservoir description. Ineffectual analysis often leads to poor completion and high water production. Integrating multifrequency-dielectric and nuclear-magnetic-resonance (NMR) logs leads to improved carbonate-reservoir evaluation.
Dielectric and NMR logs have similar depths of investigation, both probing the flushed zone. It is difficult to distinguish bound water from heavy oil in rocks from NMR tools alone. The addition of accurate water-filled-porosity (ϕW) measurements from the dielectric log allows us to differentiate the fluids. Using ϕW as a reference and accounting for restricted molecular diffusion in small pores, NMR analysis on the basis of diffusion relaxation provides more-accurate oil viscosity and fluid volumes.
The computation of viscosity from NMR assumes that the oil relaxation is dominated by bulk relaxation; oil-wetting of pore surfaces causes viscosity to be overestimated. Conversely, the wetting state can be inferred if the viscosity is known. Dielectric dispersion with frequency provides a measure of the water-phase tortuosity MN_De, which in turn is affected by texture and wettability. We compared the in-situ NMR signal of oil to the surface NMR measurement of a bulk-oil sample. We also identified a correlation between MN_De and the Archie cementation exponent, mainly driven from NMR. This leads to interesting conclusions about texture and wettability, which are found to be coherent with the existing reservoir data.
Together with the viscosity profile, the comparison between the pore-fluid volumes in the flushed zone and the bulk volume of water from deep resistivity is used to identify the zones of movable oil and to estimate residual oil saturation. The method was applied to data sets from three wells in a shallow carbonate reservoir. The estimated viscosity was validated by pressure/volume/temperature (PVT) analysis. In two wells, the prediction of movable oil and water zones was confirmed by downhole test results. In the third well, the free-water zone was confirmed by production logging.

Published: May 2017

Background:Systemic sclerosis is an autoimmune connective tissue disease with significant pain, fatigue, and disability. Patients with systemic sclerosis are at increased risk for psychiatric disorders.Objective:This study assessed the personality and psychopathological characteristics of scleroderma patients.Method:Consecutive, in-patient female cases with systemic sclerosis (N=72) from the tertiary care center of the University of Pécs and age- and sex-matched healthy volunteers (N=56) and fifty patients with rheumatoid arthritis were enrolled. Participants completed the Minnesota Multiphasic Personality Inventory-2. Demographical and clinical data were also collected.Results:Rheumatoid arthritis and scleroderma patients had similar profiles with high scores (≥65T) on Scales 1, 2 and 3. Additionally, they achieved moderate scores on Scales 5 and 0. The Scale 7 was elevated only in females with rheumatoid arthritis distinctively.Conclusion:High scores on Scales 1, 2 and 3 may reflect the severe somatic symptoms of systemic sclerosis (and rheumatoid arthritis), but may also refer to the disease-related emotional distress, anxiety and depression. Likewise, social withdrawal and less feminine interests may be the results of the chronic and disabling illness. The minor differences between the patient groups indicate that females with systemic sclerosis may be less vulnerable to specific anxiety disorders (obsessive-compulsive disorders, phobias). Study results highlight the importance of developing psychosocial interventions designed to meet the needs of scleroderma patients.

Authors: Al Zebary Marwan K. , Yousif Samira Y. , Assafi Mahde S. 
Published: May 2017

Background:Staphylococcus aureusis one of the most important opportunistic pathogens. Impetigo is the common contagious bacterial infection of the skin caused byS. aureus.Method:Samples were taken from 204 patients with impetigo disease.S. aureusisolates were tested for their antimicrobial susceptibility. Genomic DNA ofS. aureuswas used to transformE. coliHB101 strain and expression capability ofS. aureusplasmids in transformedE. coliwas investigated. 68.62% (140/204) of the specimens were nonbullous impetigo and 31.38% (64/204) were bullous impetigo.S. aureusstrains were isolated from 41.66% (85/204) of impetigo cases (82.35% from nonbullous and 17.65% from the bullous impetigo). There was an inverse relationship between the incidence ofS. aureusisolated and age.Result:Three biotypes ofS. aureuswere identified based on their fermentation of different sugars. All isolates were resistant to penicillin and most isolates were resistant to ampicillin (95.3%), amoxicillin, (94.11%) and cephalexin (90.95%). Most isolates were sensitive against vancomycin and rifampicin (98.83%). 5.88% (5/85) ofS. aureusisolates were identified as MRSA. A maximum of 5 markers fromS. aureusisolates were capable to be expressed in transformedE. coliHB101 strains. The incidence of impetigo caused byS. aureusis comparable with reports from elsewhere.S. aureusisolates showed multidrug resistance against antibiotics.Conclusion:Plasmids ofS. aureusare capable to show its expression inE. coliHB101. Molecular study is needed to investigate the role of plasmids in different patterns of multi drug resistance.
Comparison of PV Cell Temperature Estimation by Different Thermal Power Exchange Calculation Methods

Published: May 2017

A steady-state thermal model for calculate the tem-perature of a photovoltaic (PV) module has been developed for outdoor installation such as ground-mounted systems. The PV temperature is influenced by environmental variables such as: irradiance ambient temperature, intensity and direction of the wind, module design, orientation and mounting structure. As well as it is influenced by electrical parameters. In literature some single layer thermal balance consider only an overall heat transfer coefficient as a function of wind speed, neglecting the radiative thermal flux. In this paper, five thermal balance are compared and it is shown that the radiative term cannot be neglected, otherwise the PV temperature could be overestimated for low solar radiation intensity and it could be underestimated for high solar radiation intensity. For this reason, the percentage contribution of the heat exchanges, normalized as function of normal incoming solar radiation, are evaluated for wind speed within 1 m/s (natural convection).
Research on Control Strategies of a Stand-alone Photovoltaic System
Authors: Qiu Bin  , Ma Yundong  
Published: May 2017

In order to assure that the system can run stably under different modes, energy storage equipment—Lead-Acid battery is added to the conventional two-stage PV system. PV panels and batteries are parallel connected to the DC-bus through a unidirectional Boost converter and a bidirectional Buck/Boost converter respectively. A full bridge inverter is linked to the DC-bus as the second stage of the system which is in charge of DC-AC power transforming for the AC loads. Control methods and power management strategies of a two-stage stand-alone photovoltaic system are proposed in this paper. A 500W experiment prototype is constructed to verify the theoretical analysis of the control methods and power management strategies.
Comparison of methods for implementing virtual synchronous machine on inverters
Authors: Yong Chen  , Ralf Hesse  , Dirk Turschner  , Hans-Peter Beck  
Published: May 2017

Virtual Synchronous Machine also called VISMA [1] is a control algorithm to make an inverter operated as a conventional electromechanical synchronous machine. It is a promising solution to overcome the problems of the grid stability and quality, which have been exacerbated by increasing integration of distributed generation units into the grid. Compared to the conventional power plants, in which the synchronous machine dominate, the distributed generation units have either significantly smaller or no rotating mass and damping effect. These weaknesses can be compensated by using the VISMA concept and thus the power system quality will be improved. Furthermore, the penetration level of the DG sources won’t berestricted any more. Up to now the VISMA was implemented by using a voltage-to-current model on a hysteresis controlled inverter [1][2][3]. This method will be called VISMA-Method 1 here. Since the most products of inverters in the market are PWM controlled, the VISMA-Method 1 cannot be easily applied on these inverters. Therefore, a new method is developed to implement the VISMA by using a current-to-voltage model on the currently widely applied PWM controlled inverter. This new method is called VISMA-Method 2 in this paper and will be compared with the VISMA-Method 1 by simulation results.

Published: May 2017

Based on existing installations of heating and cooling of the municipal sports centre of Ordizia (Spain) and its operating data, the remodelling of these facilities has been discussed according to new regulations. In order to facilitate decision-making reform of the facilities, this will be approached from eco-efficiency criteria, i.e. taking into account not only the usual economic and technological criteria (business as usual-BAU), but also integrating the concept of life cycle analysis (LCA) of the installation, allowing therefore to analyze the environmental impact prior to its implementation.The comparison between two types of boilers, the current diesel one and a high performance natural gas equipment, is presented in this first part. In both cases, the major impact has been found during the use stage compared with the stages of construction and dismantling, due mainly to the use of fuel. Thus, the used fuel has great influence on environmental impact, resulting to be the natural gas boiler the best option.

PENJATUHAN PIDANA BERSYARAT TERHADAP PELAKU TINDAK PIDANA PENGANIAYAAN
Authors: Nugraha Adia 
Published: May 2017

abstractBasic considerations of criminal law judges in imposing conditional on the perpetrators of criminal acts of persecution are juridical considerations, namely the fulfillment of a minimum of two items of evidence in the trial, the judge considered that there are justification, an excuse and a reason for removing the judge the prosecution to convict on parole. Beside the judges also look at the background of the events of the crime as a whole as well as the attitudes and actions of the defendant in the community daily. The defendant did cause by the maltreatment victims who are not acting in good faith to the defendant as a guarantor of loans receivable in the pawnshop and the defendant has been helping victims to get a loan. Court decisions that criminalize conditional against an abuser are deemed not in accordance with the justice community because judges are less sensitive to the suffering of victims of the crime of persecution by the defendant. The judge should impose a more optimal criminal defendant, given the criminal acts of persecution that resulted in physical harm to the victim in the form of bruises and abrasions due to blunt impact. Keywords: Imposition, Conditional Punishment, PersecutionabstrakDasar pertimbangan hukum hakim dalam menjatuhkan pidana bersyarat terhadap pelaku tindak pidana penganiayaan adalah pertimbangan yuridis sebagaimana diatur Pasal 184 KUHAP, hakim menilai bahwa terdapat alasan pembenar, alasan pemaaf dan alasan penghapusan penuntutan bagi hakim dalam menjatuhkan pidana bersyarat. Selain itu hakim juga melihat peristiwa yang melatar belakangi perbuatan pidana tersebut secara keseluruhan serta sikap dan perbuatan terdakwa sehari-harinya dalam masyarakat. Terdakwa melakukan penganiayaan disebabkan oleh korban yang tidak beritikad baik kepada terdakwa sebagi penjamin hutang piutang di Pegadaian dan terdakwa telah menolong korban untuk mendapatkan pinjaman. Putusan pengadilan yang menjatuhkan pidana bersyarat terhadap pelaku tindak pidana penganiayaan dipandang belum sesuai dengan keadilan masyarakat karena hakim kurang sensitif terhadap penderitaan korban akibat tindak pidana penganiayaan oleh terdakwa. Hakim semestinya menjatuhkan pidana yang lebih optimal kepada terdakwa, mengingat tindak pidana penganiayaan yang dilakukan tersebut mengakibatkan penderitaan fisik pada korban berupa luka memar dan lecet akibat benturan benda tumpul.
