Over the last few decades, the atmospheric carbon dioxide emission has been amplified to a great extent in Turkey. This amplification may cause global warming, climate change and environmental degradation in Turkey. Consequently, ecological condition and human life may suffer in the near future from these indicated threats. Therefore, an attempt was made to test the relationship among a number of expected factors and carbon dioxide emissions in the case of Turkey. The study covers the time series data over the period of 1970–2017. We employed the modern econometric techniques such as Johansen co-integration, ARDL bound testing approach and the block exogeneity. The results of the Johansen co-integration test show that there is a significant long-run relationship between carbon dioxide emissions and expected factors. The long-run elasticities of the ARDL model show that a 1% increase in the GDP per capita, electric consumption, fiscal development and trade openness will increase carbon dioxide emissions by 0.14, 0.52, 0.09 and 0.20% respectively. Further, our findings reveal that the environmental Kuznets curve (EKC) hypothesis and inverted U-shaped relationship between carbon dioxide emission and economic growth prevails. Therefore, the EKC hypothesis is valid and prevailing in the Turkish economy. The diagnostic test results show that the parameters of the ARDL model are credible, sTable and reliable in the current form. Finally, Block exogeneity analysis displays that all the expected factors are contributing significantly to carbon dioxide emissions in the Turkish economy.

We report the static magnetic properties of Maghemite (-Fe2O3) nanoparticles with an averagecrystallite size of 14 ± 1.8 nm synthesized via a co-precipitation method. The zero-field-cooled(ZFC) and the field-cooled (FC) magnetization measurements were performed using a physicalproperties measurements system (PPMS) at temperatures from 5 K to 300 K. The ZFC/FC measurementsshowed a typical superparamagnetic behavior with a narrow size distribution.

The infectious bursal disease (IBD) is a highly contagious and acute poultry disease caused by Birnavirus. However, the vaccination is the only disease prevention, but several factors impeded vaccine development. Thus, a need for time to develop a novel technique for managing and treating respiratory diseases in poultry birds. Passive immunization is a hope and a possible alternative used in birds to meet this need. The current research attempted to produce egg yolk-based polyclonal antibodies against the IBD virus. The benefits of IgY include ease of extraction, lack of reaction with mammalian Fc receptors, and low production cost. Commercial layers were immunized with inactivated IBD virus subcutaneously according to the treatment regimen. The eggs were gathered daily, and yolk antibodies were extracted with the ammonium sulfate precipitation technique. The use of an indirect hemagglutination test demonstrated that IgY was IBD-specific. Until the end of the experiment, the specific IgY immunoglobulins did not lose activity when stored at 4℃. The specific immunoglobulin (IgY) treated challenged birds were demonstrated 92% recovery in comparison to the control group. The study implies that the IBDV specific IgY is an easily prepared and rich source of antibodies and offers an alternative therapeutic agent to cure IBD-infected birds.

Complete Heart Block in Association with Dengue Hemorrhagic Fever

Hafeez Ul Hassan Virk,Faisal Inayat,Zia Ur Rahman 대한심장학회 2016 Korean Circulation Journal Vol.46 No.6

Dengue virus infection affects the heart structurally and functionally. Clinical manifestations of cardiac complications secondary to dengue virus infection vary from self-limiting arrhythmias to severe myocardial infarction, leading to hypotension, pulmonary edema, and cardiogenic shock. However, we report a case of dengue hemorrhagic fever (DHF) complicated by a complete heart block. A female with DHF due to dengue virus serotype 2, presented to the emergency department with fever, headache, rash, and fatigue followed by an episode of syncope. She was found to have a third-degree atrioventricular block, with pulseless polymorphic ventricular tachycardia. Patient was resuscitated and a temporary trans-venous pacemaker was placed. She reverted back to normal sinus rhythm after 4 days of syncope and was subsequently discharged from the hospital after complete resolution of symptoms, without the need for a permanent pacemaker. Physicians are warranted to have high index of suspicion for dengue virus infection as an etiology in patients with acute cardiovascular compromise, especially in tropical areas.

Electrochemical characterization and thermodynamic tendency of β-Lactoglobulin adsorption on 3D printed stainless steel

M.J.K Lodhi,K.M. Deen,Zia Ur Rahman,Ameeq Farooq,Waseem Haider 한국공업화학회 2018 Journal of Industrial and Engineering Chemistry Vol.65 No.-

The electrochemical behavior of 3D printed 316L stainless steel (3DPSS) was investigated in phosphate buffer saline (PBS), containing β-Lactoglobulin (BLG). The charge transfer resistance (Rct) was decreased from 629 to 40 k Ω cm2 with an increase in temperature from 293 to 323 K in BLG free electrolyte. At each temperature, the exponential decrease in the polarization resistance (Rp) of 3DPSS was a function of BLG concentration. The significant decrease in activation energy ‘Ea’ (∼15 kJ mol−1) upon adding 0.06 g/L BLG attributed to the charge transfer process involved in the adsorption process. The results were further used to quantify the thermodynamic parameters.

In this project, ovarian size and activity during the peak (November-April) and the low (May-October) breeding seasons in young and adult camels were studied. Ovaries of 92 camels (Camelus dromedarius), with clinically normal reproductive tracts, aged 3-15 years and slaughtered at Faisalabad or Lahore abattoirs over a period of 24 months, were collected. Jugular blood was collected from each animal before slaughter; the serum was separated and analyzed for oestradiol concentration. The size (length, width and thickness) and weight of each ovary were measured. Grossly observable Graafian follicles were counted and their diameter was measured using Vernier Calipers. The camels having ovaries presenting follicles more than 5 mm in diameter were taken as having active ovaries. The results showed that ovarian length, width and weight were significantly higher (p<0.05) during the peak than the low breeding season. The percentage of active ovaries was also significantly higher (p<0.01) during the peak than the low breeding season. However, the effect of season on ovarian thickness was non-significant. Similarly, the ovarian length, width, thickness, weight and activity did not vary significantly between young (3-7 years old) and adult (8-15 years old) animals. Serum oestradiol concentrations were significantly higher (p<0.05) during the peak ($67.70{\pm}1.36$ pg/ml) than the low breeding season ($15.25{\pm}1.54$ pg/ml). It was concluded that in Pakistani camels ovarian size and activity were higher during the peak than the low breeding season. However, age of the camel (from 3 to 15 years) had no effect on these parameters.

Interference-aware routing protocol design for underwater wireless sensor networks (UWSNs) is one of the key strategies in reducing packet loss in the highly hostile underwater environment. The reduced interference causes efficient utilization of the limited battery power of the sensor nodes that, in consequence, prolongs the entire network lifetime. In this paper, we propose an energy-efficient interference-aware routing (EEIAR) protocol for UWSNs. A sender node selects the best relay node in its neighborhood with the lowest depth and the least number of neighbors. Combination of the two routing metrics ensures that data packets are forwarded along the least interference paths to reach the final destination. The proposed work is unique in that it does not require the full dimensional localization information of sensor nodes and the network total depth is segmented to identify source, relay and neighbor nodes. Simulation results reveal better performance of the scheme than the counterparts DBR and EEDBR techniques in terms of energy efficiency, packet delivery ratio and end-to-end delay.
