Authors: Ashraf Mohd , Bhat Firdous Ahmed , Tak Shafat Ahmed , Iqbal Javaid , Kambay Altaf Hussain , Riyaz Anisa
Published: April 2019

Background: Acute kidney injury (AKI) is a common entity in neonates admitted to the neonatal intensive care unit (NICU). Neonatal AKI is associated with increased morbidity and mortality and a greater risk of chronic kidney disease among the affected ones in future. Objectives: The objectives of this study were to study the incidence and outcome of neonatal AKI in our NICU. Materials and Methods: This single-center retrospective study included all infants who were admitted in a tertiary care hospital, J and K, from June 2013 to May 2014. Neonates, who had known congenital kidney diseases or if they did not survive beyond the first 48 h of life or had a hospital stay for <24 h, were excluded from the study. AKI was defined according to the kidney disease: Improving global outcomes criteria. Both AKI and non-AKI neonates were followed up until NICU discharge. Outcomes studied included mortality and length of NICU stay. Results: A total of 1439 neonates were studied among whom 72.89% (1049/1439) were normal weight, 11.46% (165/1439) were low birth weight, and 15.63% (225/1439) were very low birth weight. Of 1436 studied, 72% (1036) were term babies and 28% (403) were preterm babies. Perinatal asphyxia accounted for 43% (620/1439), seconded by neonatal sepsis 31.6% (455/1439) as a cause of NICU admission. Incidence of neonatal AKI in our study was 8.33% (120/1439). Mortality rate among the neonatal AKI patients was 34.1% (41/120). Conclusion: Our study shows an incidence of 8.3% among the NICU patients with a high mortality rate of 34.1%, implying a heightened awareness and very close monitoring of renal function during hospitalization and after discharge in such infants.

Published: April 2019

Brucellosis, which is believed and categorized as an animal disease, can, surprisingly, be found in humans also. We report a 5-year boy presenting to us with prolonged (5 months) unexplained fever, non-tender discrete lymphadenopathy, and hepatosplenomegaly and finally proved to be a case of brucellosis, which was treated appropriately. Brucellosis should be considered as one of the differential diagnoses causing prolonged fever in children.

Calendars in Time-Cost Trade-Off
Authors: Csordas Helga
Published: April 2019

In project management, there are two main operation problems. Scheduling and cost optimisation. These are interrelated and have mathematically proven solutions for the basics. However, in case of applying arbitrary calendars, there may be generated such effects in scheduling that make the known time-cost trade-off model unusable. In consideration of these effects, this paper aims to apply known algorithms that have been successful for other problems.

Published: April 2019

Putting citizens in the position of city planners while giving them a sense of purpose and plans' ownership is a difficult task since the win-win effect of participating in mobility planning is, in the majority of cases, not properly communicated. Aiming to display to travelers the value of their contribution with ultimate scope to increase the participatory approach in Sustainable Urban Mobility Plans (SUMP) concept, the current paper presents the e-platform of MOTIVATE project (MED programme, 2014-2020) developed to cover low citizens' engagement levels. MOTIVATE e-platform is estimated to become a useful tool on the hands of city planners and transport engineers via which, the daunting task of data collection and idea/views/opinions capturing will be facilitated. Furthermore, the exploitation of MOTIVATE e-platform is estimated to support travel behavior change towards environmental friendly ways of transport and increase the acceptability, and thus the efficiency, of sustainable mobility plans.
Cyclic Timetable Scheduling Problem on High-speed Railway Line
Authors: Xu Wen , Tan Yuyan , Sharma Bishal , Wang Ziyulong
Published: April 2019

Due to several obvious advantages both in transport marketing and train operation planning, the cyclic timetable has already applied in many high-speed railway (HSR) countries. In order to adopt the cyclic timetable in China's HSR system, a Mixed Integer Programmer (MIP) model is proposed in this paper involving many general constraints, such as running time, dwell time, headway, and connection constraints. In addition, the real-world overtaking rule that concerning a train with higher priority will not be overtaken by a slower one is incorporated into the cyclic timetable optimization model. An approach based on fixed departure is proposed to get a cyclic timetable with minimum total journey time within a reasonable time. From numerical investigations using data from Guangzhou-Zhuhai HSR line in China, the proposed model and associated approach are tested and shown to be effective.

Authors: Tarasenkov Mikhail V. , Poznakharev Egor S. , Belov Vladimir V.
Published: April 2019

The simulation program by the Monte Carlo method of pulse reactions of bistatic atmospheric aerosol-gas channels of optical-electronic communication systems (OECS) is created on the basis of the modified double local estimation algorithm. It is used in a series of numerical experiments in order to evaluate statistically the transfer characteristics of these channels depending on the optical characteristics of an atmosphere plane-parallel model for wavelengths λ = 0.3, 0.5, and 0.9 μm at a meteorological visibility range SM = 10 and 50 km. The results are obtained for a set of basic distances between the light source and the light receiver up to 50 km and for the angular orientations of the optical axes of a laser radiation beam and of the receiving system in a wide range of their values. The dependences of the pulse reactions maximum values over-the-horizon channels of the OECS on the variations of these parameters are established.

Authors: Ates Seher , Yurtseven Mustafa B. , Onaygil Sermin
Published: April 2019

As the equipment is improving, the luminous efficacy of Chip on Board (COB) LEDs are increasing. In this study, the utilization of COB LEDs in an industrial high-bay luminaire, which can be considered as a relatively high power application, has been investigated starting from the initial design process. For an industrial hall, single-chip LED based reference luminaires, which can provide the required lighting quality criteria have been identified. COB LED selection and photometric measurements are done, and the number of COB LEDs to be used has been calculated by targeting the luminous flux value of reference luminaires. The COB LED based luminaire prototype with a plate finned heat sink was modelled by using a CAD software and the computer aided thermal simulations were performed. Then the prototype was manufactured and experimentally analysed. The highest difference between the experimental analysis and the thermal simulation was found to be less than 7 %, which demonstrates the consistency of design and analyses. This study is an example of the steps to be followed in the manufacturing stage of a COB LED based luminaire. Additionally, it is aimed to provide a perspective to the use of COB LEDs in high power applications.

Published: April 2019

Magnetic materials are present in rewriteable disk drives, electric motors and generators, and signal transformers/receivers. To improve the performance of these and other devices, much research in magnetism continues to be done. In particular, materials that are disordered on the atomic and nanometer scales have recently been the subject of extensive research, as the arrangement of atoms and the interactions between them significantly affect a material’s magnetic properties. We have prepared a disordered pure gadolinium (Gd) system using a melt-spinning technique. This resulted in a system of Gd crystals on the order of 160 nm in size embedded in an amorphous Gd matrix. The structure was identified using X-ray analysis and transmission electron microscopy. AC susceptibility and DC magnetization measurements at various temperatures (280 -350 K) and DC bias fields (0 – 3 kOe) were performed on a sample of the nanocrystalline Gd. Using modified Arrott-Noakes plots and scaling ideas for a second-order phase transition, critical exponents and the Curie temperature (TC) for the ferromagnetic transition in the nanocrystalline Gd system were obtained. TC was found to be 289.70 K, and the critical exponents had shift away from those of bulk Gd and toward those of the Heisenberg model with short-range interactions, indicating that melt-spinning suppressed the interactions present in bulk Gd.
A Graph Theoretical Approach to DNA Fragment Assembly
Authors: Kaptcianos Jonathan
Published: April 2019

Built on prior work on sequencing by hybridization, fragment assembly is a newly explored method of determining whether or not a reassembled strand of DNA matches the original strand. One particular way to analyze this method is by using concepts from graph theory. By constructing data models based on these ideas, it is possible to come to various conclusions about the original problem regarding reassembled strands of DNA. In this paper we will detail this approach to DNA fragment assembly and present some related graph theoretical proofs in the process, including the BEST theorem. Further, we will explore the Eulerian superpath problem and its role in aiding fragment assembly, in addition to other recent applications of graph theory in the field of bioinformatics.

Immunity is an important biological property of organisms that protects them from parasites. Similarly, body size is one of the most important biological traits because almost all biological processes, from the cellular to the ecosystem level, scale with body size. Our goal was to determine the correlation between body size and immune function in different populations of the eastern lubber grasshopper (Romalea microptera) which differ in body size. Field data was collected on grasshopper location, size (thorax and femur lengths), and immune function (measured by melanization response). In accordance with previous work, we found a significant body size cline among populations of south Florida grasshoppers: on average, small adult grasshoppers are found in western populations whereas large grasshoppers are found in eastern populations. However, we did not find a significant relationship between body size and one measure of immune function, either within or across these populations. Future work should be directed at understanding when body size and immune function might or might not be correlated.

The molecular distribution of the cyanine dye (5-chloro-2-[3-[5-chloro-3-(4-sulfobutyl)-2(3H)-benzothiazolylidine]-1-propenyl]-3-(4-sulfobutyl)-benzothiazolium hydroxide triethylamine salt, NK-3796) in aqueous solution was investigated using absorption and emission spectroscopy. Dimers of the dye are formed in concentrated solutions, while monomers dominate more diluted solutions. J aggregates are formed in solutions containing electrolytes such as sodium chloride, calcium chloride, and di-hydrogen ammonium phosphate. The dye readily forms J aggregates upon mixing with electrolyte. The J aggregates formation was followed spectroscopically by the appearance of a red-shifted narrow band centered at 653 nm in the absorption spectra. A similar shift is also observed in the emission spectra. The absorbance bandwidth is dependent on the charge of the cation of the electrolyte. This suggests different ground-state conformations for the J aggregates in solution.

Field studies on the efficacy of bio-control agents (lacewing and Trichograma) in the management of okra pests were carried out at the trial area of Entomology Section, Agriculture Research Institute, Tando Jam. Seeds of okra (Subz pari) were sown on 7th February 2017 in a complete randomized block design with three replications. The biocontrol agents, lacewing and Trichogramma (1300 eggs/card) each were released. Lacewing was found very effective against aphid, jassid and whitefly in the field. Aphid was found at early stage of crop and touched the maximum level in midFebruary, therefore its population decreased quickly. Jassid increased linearly and was high after 6th week of observation and then decreased subsequently till picking of the crop. On the other hand, whitefly population increased linearly till 9th week of observation and then decreased and eventually disappeared from the crop on 19th week of observation. Trichogramma was observed as a main natural enemy of spotted bollworm of okra and reduced bollworm population. The population of bollworm increased slowly till harvesting of the crop. It is concluded from the present study that both the bio-control agents successfully lowered the populations of sucking and chewing insect pests and bollworms of okra. Lacewing was found effective against sucking insect pests while Trichogram efficiently controlled bollworms and are recommended for field applications. These bio-control agents can also be incorporated in IPM strategy

Charcoal rot is one of the major threats to sunflower which causes complete crop loss in epidemic conditions. The genetic resistance of sunflower germplasm could be more economical and durable approach for the management of charcoal rot. In the current experiment, six genotypes obtained from Ayub Agricultural Research Institute, Faisalabad were evaluated for their resistance and morphological parameters against Macrophomina phaseolina. Under field conditions, none of the cultivars gave immune or resistant response against the disease. FH-337 was found to be susceptible with 54.87% infection while FH-331, FH-106 and Hycanth-33 appeared moderately susceptible with 25-49% infections. The least affected varieties were FH-259 and DK-40 with moderately resistant status in the range of 10-24%. Yield parameters of resistant varieties were better than susceptible ones when compared under inoculated conditions. Moderately resistant genotypes might have the better genetic makeup and could be selected in breeding programs to find out resistant sunflower germplasm to fulfill the needs of growing population. Moreover, these cultivars could be used for better yield of sunflower.

Leaf rust occurs worldwide wherever wheat is grown. The current research was planned to evaluate the response of 37 wheat (Triticum aestivum) genotypes against leaf rust resistance under field conditions during crop season 2017-18.These genotypes were sown in augmented design with two meter long line sowing method with 30 cm row to row distance at research area of Agricultural Biotechnology Research Institute (ABRI), Ayub Agricultural Research Institute (AARI), Faisalabad, Pakistan. After every five genotypes, a line of rust spreader “Morocco” was sown. Moreover, the trial was also surrounded by planting two rows of spreader to increase the inoculum pressure. Data was recorded on the basis of leaf rust severity scale. Leaf rust severity response was variable among tested genotypes. Out of thirty-seven genotypes, five wheat lines were immune (no disease symptoms) i.e. 17BT007, 17BT013, 16BT008, 16BT010 and 16BT011. Seven lines were found to be resistant with AUDPC vales ranged 1-199. Response of ten lines was moderately resistant while five lines were categorized as moderately susceptible. Ten genotypes exhibited susceptible response against leaf rust with more than 600 AUDPC value. High values above 600 of AUDPC showed greater incidence of leaf rust on wheat plants while lower AUDPC values indicated resistance to leaf rust. Present research provided the resistant wheat lines to the breeders to incorporate them in their breeding program against leaf rust.

Potato (Solanum tuberosum) is considered as staple food and ranks fourth after wheat, rice and maize in Pakistan. Many biotic constraints affect potato production as potato cyst nematodes (Globodera spp.) are considered to be the most important quarantine pests of potato posing serious potential economic consequences throughout the world. Two hundred soil samples comprising of Okara, Sahiwal, Kasur and Pakpattan districts were analyzed by floatation technique at Plant Pathology Research Institute, Faisalabad and were found free from Potato Cyst Nematodes (PCN) infestation. Soil health study was also carried out following standard analytical techniques and soil health indicators for arable land like organic matter, extractable potash, available phosphorus and microbial populations were found in sufficient levels to ensure healthy crop production.

Published: April 2019

Although rare, cardiac myxomas are the most common primary cardiac tumor with an incidence of 0.5 per million per year. Previous case series have reported on the epidemiology, clinical characteristics, diagnostic technologies and therapeutic outcomes that were evident at the time of publication. Because of the evolution of cardiac diagnostic (particularly imaging) and therapeutic options, we theorized that cardiac myxomas would be found at an earlier stage and this would result in improved therapeutic outcomes. Accordingly, a new case series (Current Group) is being reported and compared to historical case series that were published after widespread availability of echocardiography (after 1985). The case series were further divided into those published before (group 3), after (group 1) or overlapping (group 2) the proliferation of chest and cardiac imaging technologies that occurred in the mid-1990s. All 28 patients with pathologically proven cardiac myxoma at Florida Hospital Orlando from April 2007 to August 2013 (the Current Group) were studied. For comparative review, PubMed was searched for case series of cardiac myxoma from January 1, 1985 to December 31, 2013, and studies that met inclusion criteria were divided into three groups: Group 1: cases collected exclusively after 1995 (10 articles); Group 3: cases exclusively before 1995 (31 articles); and Group 2: those not belonging to group 1 or 3 (23 articles). The gender (2:1 female predominance), age and myxoma location (85% left atrium) have not changed significantly over time. However, the tumor size has declined from 5.3 cm to 3.3 cm. Asymptomatic cases (found unexpectedly) have increased to 21% of the Current Group while fever, heart failure and embolism have declined over time. Echocardiography has become the dominant diagnostic technology, followed by CT. Catheter based diagnostic imaging has declined substantially. Surgical mortality and tumor recurrence have remained low but unchanged. In summary, cardiac myxoma has trended to smaller, more frequently asymptomatic tumors found mostly by echocardiography or CT, but this has not altered surgical mortality or recurrence.

This article presents the research results on Mutual Recognition Agreement effect on the volume of exports – imports of the countries (parties) in the context of the EU – Israel Mutual Recognition Agreement. The authors used the Chow test to obtain the results. The article shows that there is no good reason to believe that Mutual Recognition Agreements boost the volume of mutual trade, at least, of pharmaceutical products. In other words, Mutual Recognition Agreements do not contribute to the growth in the number of exporters. It is concluded that the primary effect of such agreements is to facilitate conformity assessment procedures.

Diabetes mellitus (DM) is a group of metallic disorder characterized by steep levels of blood glucose prolonged over a time. It results the defection in insulin production or improper action of the cells to the insulin produced. It is one of the significant public health care challenge worldwide. Diabetes exists in a body when pancreas does not construct enough hormone insulin or the human body is not being able to use the insulin properly. The diagnosis of diabetes (diagnosis, etiopathophysiology, therapy etc.) need to generate and process the vast amount of data. Data mining techniques have proven its usefulness and effectiveness in order to evaluate the unknown relationships or patterns if exists with such vast data. In the present work, five techniques based on machine learning namely, AdaBoost, LogicBoost, RobustBoost, Naïve Bayes and Bagging have been proposed for the analysis and prediction of DM patients. The proposed techniques are employed on the data set of Pima Indians Diabetes patients. The results computed are found to be very accurate with classification accuracy of 81.77% and 79.69% by bagging and AdaBoost techniques, respectively. Hence, the proposed techniques employed here are highly adorable, effective and efficient in order to predict the DM.
