A Biochemical Study for Evaluation and Analysis of Serum Protein of Patients with Different Kidney Tumors
Authors: Journal Baghdad Science
Published: March 2019

The amount of protein in the serum depends on the balance between the rate of its synthesis, and that of its catabolism or loss. Abnormal metabolism may result from nutritional deficiency, enzyme deficiency, abnormal secretion of hormones, or the actions of drugs and toxins. Renal cancer is the third most common malignancy of the genitourinary system, and accounts for 3% of adult malignancies globally. Total serum proteins were measured in malignant kidney tumor, benign kidney tumors, and non tumoral kidney diseases patient groups, as well as in healthy individuals. A significant decrease (p< 0.001) of total serum protein levels in patients with malignant kidney tumors when compared with those of benign tumors, non tumoral diseases, and healthy individuals. The lowest serum protein levels were found in patients with stage IV, regardless their genders. Analysis of total serum proteins using PAGE revealed clear differences in the number and shape of the bands in patients with different kidney diseases compared with healthy controls.

Published: March 2019

Background

Mini-fluid challenge is a well tested and effective tool to predict fluid responsiveness under various clinical conditions. However, mini-fluid challenge has never been tested in patients with end-stage liver disease. This study investigated whether infusion of 150 ml albumin 5% can predict fluid responsiveness in cirrhotic patients following liver transplant.

Methods

Fifty patients receiving living donor liver transplant were included in the analysis. Mini-fluid challenge composed of 150 ml of albumin 5% administered over 1 min in three consecutive 50-ml fluid boluses. An additional 350 ml was then infused at a constant rate over 15 min (for a total of 500 ml). Stroke volume (SV) was measured as the product of the subaortic velocity time integral (VTI) and left ventricular outflow tract (LVOT) area. Fluid responsiveness was defined as an increase in SV by ≥15% after the infusion.

Results

Fifty patients were enrolled in the study. Fourteen patients were classified with Child A, 15 patients with Child B, and 21 patients with Child C cirrhosis. Thirty four patients were fluid responders and 16 patients were fluid non-responders. After 150 ml of albumin 5%, the SV increased significantly in our cohort. The area under receiver operating curve (AUROC) was 0.7 (95% confidence interval [CI] 0.5–0.8, P = 0.005). In subgroup analysis, the SV increased significantly after mini fluid challenge in the Child A group (P = 0.017) but not Child B or C groups (P = 0.3 and 0.29, respectively). The AUROC for mini-fluid challenge in the Child A group was 0.86 (95% confidence interval [CI] 0.6–0.9, P = 0.0004), while mini-fluid challenge failed to discriminate between responders and non-responders in Child B and C groups.

Conclusion

A mini-fluid challenge of 150 ml albumin 5% can predict fluid responsiveness in liver transplant patients with fair sensitivity and specifiicty. Subgroup analyis revealed that minifluid challenge can predict fluid responsiveness in patients with Child A cirrhosis but not patients with Child B or C cirrhosis

Ensuring the dependability of technical facilities through triplication and quadrupling
Authors: Tyurin S. F.
Published: March 2019

Redundancy, e.g. structural redundancy, is one of the primary methods of improving the dependability, ensures failsafety and fault tolerance of components, devices and systems. According to the International Patent Classification (IPC), the class of systems and methods G06F11/18 is defined as «using passive fault-masking of the redundant circuits, e.g. by quadrupling or by majority decision circuits». Obviously, «fault-masking» masks not only faults, but failures as well. The majority decision circuits (MDC) in the minimal configuration implements a «2-out-of-3» choice. According to the above definition, such redundancy should not require a special decision circuit. However, that is not always the case. In cases when the resulting signal out of a quadruple logic is delivered to, for instance, an executive device, a «3-outof-4» selection circuit is required anyway. Another dependability-improving solution is defined by class G06F 11/20, «using active fault-masking, e.g. by switching out faulty elements or by switching in spare elements». The word «active» is missing here, thus we have active and passive fault tolerance. The paper examines passive fault tolerance that uses triplication and quadrupling and compares the respective probabilities of no-failure.The Weibull distribution is used that most adequately describes dependability in terms of radiation durability under the effects of heavy ions. It shows that in a number of cases quadrupling has a lower redundancy than triplication. A formula is proposed that describes the conditions of preferability of quadrupling at transistor level.
Improving the reliability of professional psychological selection of aviation specialists
Authors: Arinicheva O. V. , Malishevsky A. V.
Published: March 2019

The research used the Thomas-Kilman Conflict Mode Instrument (TKI) (more specifically, TKI-R, the Russian adaptation by N.V. Grishina) psychodiagnostic procedure to assess the behaviour strategy in conflict situations, as well as the Buss-Durkee Inventory to determine the tendency of subjects to various forms of aggressive behaviour. Statistical processing of the findings was done using the Bravais-Pearson correlation coefficient and Pearson’s criterion.

Results.At the first stage of the multipurpose experiment 48 student dispatchers were surveyed, at the second stage the total of 603 subjects were surveyed (students of the Saint Petersburg State University of Civil Aviation and the Institute of Philology, Foreign Languages and Media Communications of the Irkutsk State University), i.e. while emphasizing operator professions in order to improve the validity of the experiment the sample was significantly extended to include, among others, students of the humanities. It was found that the results of the Buss-Durkee Inventory have an inverse correlation with the tendency to an adaptation strategy and direct correlation with the tendency to rivalry and collaboration strategies. According to Pearson’s fitting criterion, there are significant differences in the manifestation of such behaviour styles as rivalry and avoidance between pilot and humanities students, while for the samples of males and females the differences are in the manifestation of such behaviour stiles as rivalry, avoidance and compromise. Females are significantly less inclined to rivalry and somewhat more inclined to avoidance and compromise as compared to males. There are also no observable crucial differences between the intercorrelations of the TKI-R results of the first and second stages of the experiment. The authors’ findings were compared with the published results of the survey of the students of the Tuvan State University and Yaroslavl State Medical University, as well as with the results of surveys of athletes and business owners.

Conclusions.By generalizing own findings and those set forth in other authors’ publications, we can conclude that uncooperative behaviour of all tested students is dominated by average manifestation of strategies of competing, collaborating, compromising, avoiding and accommodating, which indicates the ability of the subjects of this age for flexible behaviour in conflict situations subject to the specific conditions of interaction. That means that students, unlike the success-seeking business owners, while prioritizing collaboration and compromise in conflict situations, flexibly use other behaviour strategies. This must be taken into consideration when planning measures aimed at improving the reliability of professional psychological selection in commercial aviation. It appears that in view of the above reasons, the application of the TKI-R procedure in the professional psychological selection of aviation specialists is unviable.
Clinical Operational Tolerance and Immunosuppression Minimization in Kidney Transplantation: Where Do We Stand?
Authors: Manzia Tommaso Maria , Gazia Carlo , Baiocchi Leonardo , Lenci Ilaria , Milana Martina , Santopaolo Francesco , Angelico Roberta , Tisone Giuseppe
Published: March 2019

Background:

The 20th century represents a breakthrough in the transplantation era, since
the first kidney transplantation between identical twins was performed. This was the first case of
tolerance, since the recipient did not need immunosuppression. However, as transplantation became
possible, an immunosuppression-free status became the ultimate goal, since the first tolerance case
was a clear exception from the hard reality nowadays represented by rejection.

Methods:

A plethora of studies was described over the past decades to understand the molecular
mechanisms responsible for rejection. This review focuses on the most relevant studies found in the
literature where renal tolerance cases are claimed. Contrasting, and at the same time, encouraging
outcomes are herein discussed and a glimpse on the main renal biomarkers analyzed in this field is
provided.

Results:

The activation of the immune system has been shown to play a central role in organ failure,
but also it seems to induce a tolerance status when an allograft is performed, despite tolerance is still
rare to register. Although there are still overwhelming challenges to overcome and various immune
pathways remain arcane; the immunosuppression minimization might be more attainable than
previously believed.

Conclusion:

Multiple biomarkers and tolerance mechanisms suspected to be involved in renal
transplantation have been investigated to understand their real role, with still no clear answers on the
topic. Thus, the actual knowledge provided necessarily leads to more in-depth investigations,
although many questions in the past have been answered, there are still many issues on renal
tolerance that need to be addressed.
Attenuating Effect of Portulaca oleracea Extract on Chronic Constriction Injury Induced Neuropathic Pain in Rats: An Evidence of Anti-oxidative and Anti-inflammatory Effects
Authors: Forouzanfar Fatemeh , Hosseinzadeh Hossein , Khorrami Mohammad B. , Asgharzade Samira , Rakhshandeh Hassan
Published: March 2019

Background:

Neuropathic pain responds poorly to drug treatments. The present study investigated
the therapeutic effect of Portulaca oleracea, in chronic constriction injury (CCI)-induced
neuropathic pain in rats.

Objective & Methods:

Neuropathic pain was performed by putting four loose ligatures around the sciatic
nerve. CCI resulted in the development of heat hyperalgesia, mechanical allodynia and cold allodynia
accompanied by an increase in the contents of TNF-α, IL1β, malondialdehyde, with a reduction
in total thiol content.

Results:

Administration of Portulaca oleracea (100 and 200 mg/kg intraperitoneal) for 14 days in CCI
rats significantly alleviated pain-related behaviors, oxidative damage and inflammatory cytokines in a
dose-dependent manner.

Conclusion:

In conclusion, it is suggested that the antinociceptive effects of Portulaca oleracea might
be due to antioxidant and anti-inflammatory properties.

Published: March 2019

In order to determine soil characteristics and above-ground and below-ground carbon sequestration potential of wheat, a systematic random sampling method was employed to select 5 samples from 50 fields situated in Khorasan-Razavi Province, Iran during 2015. The experimental design was a completely randomized design with three replications. The ash method was used to determine the carbon sequestration conversion coefficients in spikes, stems, leaves and roots. Then, greenhouse gases (such as CO2, N2O and CH4) emission were calculated using emission coefficients. The average organic carbon, total nitrogen, available phosphorus, available potassium, soil bulk density, pH and electrical conductivity were found to be 0.98%, 0.02%, 27.07 ppm, 341.32 ppm, 1.37 g.cm-3, 7.81 and 1.42 dS.m-1, respectively. The maximum (52.0%) and minimum (31.99%) conversion coefficients were related to spikes (seeds included) and roots, respectively. In addition, the total carbon sequestration was 8.25 t.ha-1 so that the maximum (4.28 t.ha-1) and minimum (0.35 t.ha-1) values were found in stems and roots, respectively. The total global warming potential (GWP) of wheat was recorded as 2377.86 kg CO2 –equiv. per ton of seed. The first contributing factor was nitrogen fertilizers, accounting for 1331.30 kg CO2 –equiv. per ton of seed.
Changes in Code-Switching Patterns among Hindi-English Bilinguals in Northern India
Authors: Klingler Anita
Published: March 2019

This study investigates changes in code-switching (CS) patterns among Hindi-English bilinguals in Northern India. There is a dearth of studies of naturalistic Hindi-English CS, which this study attempts to address. By recording a group of three older speakers and one of three younger speakers, the study identifies generational differences in CS behaviour. Echoing Si’s (2010) results, it finds younger speakers using more English overall, preferring to alternate between fully English or fully Hindi clauses, while older speakers insert English items into Hindi clauses more often. Finally, the paper investigates how CS reflects and aids speakers’ (linguistic) identity construction in modern India.
Switching costs and benefits affect user resistance in project implementation: Roles of positive emotions and user traditionality
Authors: Liu Shan , Zhang Yajun , Li Kaili , Tan Jing
Published: March 2019

In this study we investigated how perceived switching costs and benefits influence user resistance as a major cause of information systems project implementation failure, from the perspectives of individual emotions and traditional values. We used structural equation modeling and hierarchical
regression analysis to analyze data from 256 potential users of a new information system. Participants were employed by a telecom operator in China. Results indicated that positive emotions played a partial mediating role in the relationship between perceived switching costs and benefits and
user resistance. Further, user traditionality moderated the influence of perceived switching costs and benefits on user resistance. These findings have theoretical implications and we suggest practical ways in which managers can alleviate user resistance.
Study on the governance mechanism of rural e-commerce service centers in rural China: agency problems and solutions
Authors: Cai Yi , Wang Deqiang , Xia Chunping , Wang Cuicui
Published: March 2019

Agency problems, such as moral hazard and adverse selection, are prevalent in the public service sector, and the Chinese rural e-commerce service sector is no exception. With the focus on the top-down project ‘information and communication technology for development’ implemented in the underdeveloped areas in China, the rural e-commerce service center (RESC) operation mechanism was analyzed in this study. Based on the tension between RESC operators, local governments, and e-commerce service providers that was reported in a field survey, this study further employs the principal-agent framework to analyze the problems of asymmetric information. Based on this analysis, solutions are suggested that can remedy the moral hazard issues in rural e-commerce service delivery, including developing a service evaluation system, promoting the usage of ICTs, and enhancing rural social capital. To address the problem of adverse selection, the RESC recruitment process should be improved. Moreover, by dividing the potential RESC employees into native villagers and e-commerce entrepreneurs, the optimal subsidy schemes can be designed for both types of applicants according to their ability and sensitivity to incentive.

Otistik Çocuklarda Hayali Resim Çizebilme Performansının Otizm Derecesi ve Gelişim Tarama Testleri İle İlişkili Olarak İncelenmesi
Authors: SARI Oktay Taymaz
Published: March 2019

Araştırma otistik çocuklarda hayali resim çizebilme performansının
otizm derecesi ve gelişim tarama testleri ile ilişkili olarak incelenmesi amacı
ile tasarlanmıştır. Araştırmaya, 5-8 yaş arası toplam 17 (5 kız,12 erkek) otizm
tanısı almış,  Hayal ve Gerçek Ayrımı Ön
Değerlendirme Çalışması’nda tüm aşamaları (sözcükleri anlama, resim çiftlerini
ayırt etme ve resim tamamlama) doğru şekilde tamamlayan çocuklar alınmıştır.
Otistik çocuklar gerçek ve imkânsız varlıklara dair hayali resim çizme durumu
ve yaratıcı içerik puanı açısından değerlendirilmiştir. Ayrıca her çocuğa
gelişim tarama testleri olan Ankara Gelişim Tarama Envanteri (AGTE), Otizm Davranış
Kontrol Listesi (ABC), Peabody Resim Kelime Testi ve Gesell Gelişim Testi
uygulanarak, hayali resim çizme durumu ve yaratıcı içerik puanı tarama testleri
skorları açısından da incelenmiştir. Bulgularımız otistik çocukların resim
çiftlerinde imkânsız resmi tanımlama ve eksik resmi imkansız içerikle uyumlu
şekilde tamamlamayı başarmalarına rağmen, hayali imkansız resmi var olmayan bir
şeyi tasarlayıp çizme çizmede, özellikle insan figüründe büyük ölçüde başarısız
olmuşlardır. Otistik çocuklarda var olmayan bir şeyi tasarlayıp çizme çizebilme
performansı artan otizm derecesi ile azalmakta, gelişim tarama test skorları
ile doğru orantılı olarak artmaktadır. Otistik çocukların var olmayan bir şeyi
tasarlayıp çizmede yaşadıkları zorluğun hayal etme ve içsel temsil oluşturmadan
ziyade, planlama ve yürütme aşamalarında ortaya çıkabileceğine ve yaratıcılık,
kognitif ve dil gelişim düzeyi ve otizm derecesi ile potansiyel ilişkisine
işaret etmektedir.
Climate Change Affects Wetland Resources in Bangladesh: A Case Study on Hakaluki Haor
Authors: Hossain Mohd Shahadat
Published: March 2019

The wetlands of Bangladesh support a wide variety of floral and faunal diversity. Approximately half the area of the country can be considered as wetlands consisting of a wide variety of types ranging from haors, beels, lakes, rivers and coastal forests to deepwater paddy fields and ponds. The wetland resources of Bangladesh are of enormous economic importance. The present study has attempted to observe the present situation of existing condition of wetland resources. However these aquatic resources have been subjected to rapid degradation due to the increasing population pressure, habitat destruction as well as natural causes. Hakaluki haor is one of the major wetlands of Bangladesh. With a land area of 18,386 hectares, it supports a rich biodiversity and provides direct and indirect livelihood benefits to nearly 190,000 people. Because of the critical conditions of the haor ecology, the government of Bangladesh declared Hakaluki as an Ecologically Critical Area (ECA) in April 1999.So the Hakaluki haor area is very important site for study as wetlands conservation practice. As there are some problems in conservation process, it is very important to try and find out the main causes of wetlands degradation and keep wetlands free from such harmful impacts. The study was initiated to find out the problems and propose some suggestions to develop the wetlands conservation process. The resources users were empowered with a collective effort to build institutions and implement sustainable use practices resulting in wetland resilience of the resources.

The crystal structure of the title compound has been determined. The compound crystallized in the triclinic space group P -1 , Z = 2, V = 1839.42(18) A3 and unit cell parameters a= 11.0460(6) A, b = 13.3180(7) A, c = 13.7321(8) A, a= 80.659(3)° , b= 69.800(3)° and g= 77.007(2)° with one disordered dimethylsulfoxide solvent molecule with the sulfur and oxygen atoms are distributed over two sites; S101/S102 [site occupancy factors: 0.6035/0.3965] and O130/O131 [site occupancy factor 0.3965/0.6035]. The C22-S21 and C19-S20 bond distances of1.779(7) A and 1.788(8) A indicate that both of the molecules are connected by the disulfide bond [S20-S21 2.055(2) A] in its thiol form. The crystal structure reveals that both of the 5-bromoisatin moieties are trans with respect to the [S21-S20 and C19-N18] and [S20-S21 and C22-N23] bonds whereas the benzyl group from the dithiocarbazate are in the cis configuration with respect to [S21-S20 and C19-S44] and [S20-S21 and C22-S36] bonds. The crystal structure is further stabilized by intermolecular hydrogen bonds of N9-H35...O16 formed between the two molecules and N28-H281...O130, N28-H281...O131 and C41-H411...O131 with the solvent molecule.
Neighbouring countries – an important segment in inbound tourism An example of the European Union member states
Authors: Borzyszkowski Jacek
Published: March 2019

The aim of the article is to present the significance of neighbouring countries in the structure of inbound tourism for the member countries of the European Union. In order to achieve this aim, some secondary materials presenting the volume and the structure of tourist traffic in the analysed countries have been referred to. The structure of the article allows the Author to provide a detailed analysis of the particular problems in the discussed field. Firstly, a review of scientific literature on tourist traffic and the significance of neighbouring countries for inbound tourism is provided. The next part of the text presents the countries adjacent to the European Union member states. Subsequently, the significance of these destinations is indicated, due to the data that present the structure of inbound tourism. It transpires that in most analysed countries, their neighbouring states come as a significant - and often even the most important - segment in inbound tourism. Furthermore, neighbouring countries often take the top positions on the list of the countries the citizens of which visit particular destinations most frequently. The analysis of the structure of inbound tourism in Poland in the years 2012-2016 also indicates that the neighbouring markets form the most important segment, regardless of some changes that took place during the analysed time period. Due to the review of some relevant documents, it is indicated (on the example of Poland) that neighbouring countries are often of priority significance in the assumptions and development plans for tourism, although the ranks of the particular countries can be different. On one hand, the considerations presented in the article allow the Author to evaluate the significance of neighbouring countries for inbound tourism in the particular countries; on the other hand, they indicate the necessity of including these countries into the tourism policy, along with promotion activities undertaken in the foreign markets.

Implementación del sensor de potencia del equipo Well Analyzer para el balanceo de unidades de bombeo mecánico balanceadas por aire
Authors: Pérez Carlos Alberto , Córdoba Diego Fernando , Gaitán Oscar Felipe
Published: March 2019

Se desarrolló un software que permite llegar adecuadamente a un balanceo de las unidades balanceadas por aire en el bombeo mecánico utilizadas en ECOPETROL, mediante la implementación del sensor de potencia del equipo Well Analyzer. Dicho sensor representa una herramienta muy útil, la cual permite una medida precisa y mucho más fiable que la usada actualmente y que permite realizar análisis de corriente del motor para llegar a determinar el rango en el que se debe tener la presión en el cilindro para balancear la unidad. Se llevaron a cabo pruebas de campo donde se tomaron mediciones de corriente variando la presión del cilindro para tratar de llegar a una aproximación de que proporción y relación existe específicamente entre la presión del cilindro y la corriente de la unidad motriz en el bombeo mecánico, que facilita el proceso de balanceo. En el desarrollo del software se utilizó Visual Studio y se escribió en el lenguaje C# (C Sharp). Se utilizaron importantes librerías que permiten generar y encontrar funciones matemáticas necesarias para los análisis; se consiguió crear un software fácil de manejar, funcional y donde se lleva la secuencia para realizar un adecuado balanceo paso a paso integrando varios métodos que permiten tener un mejor criterio a la hora del balanceo en las unidades de bombeo mecánico balanceadas por aire. Por último se realizaron pruebas y validaciones para observar la eficiencia del programa.

Authors: Torrente Trujillo Armando
Published: March 2019

Se evaluaron las pérdidas de suelo en parcelas de escorrentía mediante la Ecuación USLE y la aplicación del modelo Epic (Environmental Policy Integrated Climate). Para los propósitos se seleccionaron tres fincas, localizadas en el municipio de Palestina (veredas Jericó y Pinos) y Pitalito (Finca Marengo) con manejo tradicional y alternativo de cultivos. Se realizaron los análisis físicos y químicos de los suelos en las parcelas, se instalaron pluviómetros, estructuras de captación y aforadoras para la medición de sedimentos y escorrentías en cada parcela experimental. En laboratorio se determinó la concentración de los sedimentos totales a través de procesos de filtración y secado. Se estimaron las pérdidas de suelo (ton/ha) para cada evento pluviométrico mediante la medición y aplicación de los modelos mencionados. Las parcelas con manejo alternativo mostraron perdidas de suelo significativamente menores comparadas con las parcelas tradicionales.

Published: March 2019

Uno de los cambios más significativos desde finales del siglo XX en el campo de la producción agrícola internacional y nacional, ha sido la aplicación de la agricultura de precisión. El presente artículo recoge la experiencia investigativa realizada en el distrito de riego el Juncal municipio de Palermo-Huila, donde se determinó el ambiente fisiográfico general de la zona a partir de fotografías aéreas e imágenes satelitales, estableciendo con base en el conocimiento preciso del medio natural actual, una grilla de muestreo Geo-referenciado de 143 puntos para la determinación y modelación de la probable variabilidad espacial de algunas propiedades físico-químicas de los suelos del distrito.

Con la aplicación del software Matemática 5.2 for  student, se desarrollaron ecuaciones de gobierno a partir de los parámetros determinados en las muestras que fueron recolectadas en campo. La densidad aparente y textura fueron las variables de dominio base en la modelación utilizada para la estimación de otras propiedades de los suelos como la porosidad, infiltración, capacidad de campo y punto de marchitez permanente, que en conjunto definen la dinámica del movimiento del agua en el suelo. Se aplicó el análisis estadístico de correlación, alcance y multivariado a las variables con los software MATLAB y GS+ Geostatistics for the Environmental Sciences, determinando los índices de variación en la selección del método de krigeado para el desarrollo de los modelos digitales de terreno en el software SURFER 8.0 logrando exponer la variabilidad espacial de cada variable en el área de producción agrícola, generando la base para la planificación de labores agrícolas como riego y drenaje.
