Poultry farming represents a significant sector of agriculture, playing a crucial role in ensuring high-quality produce while efficiently utilizing feed resources. The industrial development of this sector aims to achieve high yields in egg and meat production through the utilization of high-productivity poultry hybrids. The success of this approach largely depends on providing poultry with optimal feed rations that consider their physiological needs and biological characteristics. Adequate feeding plays a crucial role in achieving maximum productivity and product quality. Therefore, the development and implementation of scientifically-based approaches to poultry feeding are important strategic tasks for further poultry farming development. In this research, the influence of adding peat to the diet on the productivity and quality of eggs from laying hens was studied. The experiment was conducted on an industrial poultry farm with Hy-Line Brown W-36 laying hens. \nOur study has revealed that the use of a peat-based feed additive in the diet of laying hens has a positive impact on various productivity aspects, such as poultry live weight, viability, and egg-laying frequency. The application of peat-based feed meal, ranging from 0.5 to 1.25 kg per ton of feed for laying hens, resulted in increased egg mass compared to the control group: egg mass in Experimental Group 1 increased by 2.60%, in Experimental Group 2 by 2.90%, in Experimental Group 3 by 3.18%, and in Experimental Group 4 by 1.41% (P≤0.95). Thus, the utilization of peat-based feed meal demonstrated a positive impact on poultry live weight, viability, egg mass, and overall egg production yield.

The aim of this research consist in providing the first empirical evidence toward the effects of corporate board and CEO characteristics on firm value for the case of Romanian listed companies. We considered the following characteristics as regards board of directors: board independence, board committees, board size, and board diversity. CEO characteristics comprise age, tenure, duality, state of residence, and gender. The empirical research was employed for a sample of companies listed on the Bucharest Stock Exchange over 2007-2011. In order to catch the effects of selected variables on firm value we estimated multivariate regression models for panel data. Consistent with prior literature we employed industry-adjusted Tobin’s Q ratio to measure firm value. There resulted a positive effect of independent non-executive directors on firm value, whereas for non-executive directors the relationship was not statistically validated. Given the reduced number of companies which established board committees we concluded the lack of theirs influence on firm value. We notice a negative relationship between board size and firm value although not robust in all econometric specifications. We also find that female representation on board should be at least twenty percent in order to show a positive effect on firm value. The results provide support for a lack of any statistically significant relationship between CEO duality, CEO age, CEO tenure, and industry-adjusted Tobin’s Q ratio. Besides, CEO gender and CEO state of residence exhibit a positive effect on firm value.

Favism represents the clinical manifestation of Glucose 6-phosphate dehydrogenase (G6PD) deficiency and induces acute hemolytic anemia after the ingestion of fava beans or the consumption of several drugs such as antimalarias, sulfonamides and aspirin. It is known that aspirin is the cornerstone of percutaneous coronary intervention (PCI) and patients who are contraindicated for aspirin intake because of hypersensitivity or active gastric bleeding pose a challenge for PCI. G6PD deficiency is another condition in which aspirin treatment is generally contraindicated. We present a literature review of patients with known G6PD deficiency that needed to undergo PCI using drug eluting stent (DES) and double antiplatelet treatment.

The aim of this study was to evaluate the induced changes in curve of activity against time (Renogram) in unilateral rabbit\'s left kidney stenosis. Renal scintigraphy is a diagnostic technique imaging to evaluate the kidney and its function in which the special radioactive substance is injected intravenously. Renal activity is evaluated by gama camera machine and a curve of activity against time is plotted by computer. Changes in the shape of the renogram can be helpful in diagnosing renal diseases. Early diagnosis of renal stenosis can lead to appropriate therapy and so cause reduces involvement side effects. In order to evaluate the renogram of the left kidney stenosis, ten nonpregnant Germen female rabbits were chosen and the semi left renal artery was occluded by ligation. Scintigraphy was under anesthetic condition with using 99m-DTPA radiodrug .The radioactive substance was injected rapidly through the marginal ear vein. Immediately after intravenous injection of radiodrug scintigraphic operations were done and computerized dynamic scans were gathered to plot the renogram curve. The ROIs can be drawn in scans and radioactive counting was easily measured. In our results, the renograms showed that the graph of renal stenosis had not reached the maximum level and the evacuation phase was delayed. The percentage of radioactive substance reaching both kidneys had decreased and in the stenotic kidney it decreased drastically. It shows the stenosis status in comparison to the normal kidney. Thus scintigraphy and renograms could be used noninvasively and accurately to diagnose unilateral stenosis in the rabbit kidney.

Relay nodes are used in the transfer of the data packets to the base station (BS) via the sensor nodes (SN). The placement of RNs influences the lifetime and connectivity of a Wireless Sensor Network (WSN) system. A traffic aware random deployment technique for the relay nodes is proposed in this paper. The scalability and traffic of the WSN are analyzed. A traffic aware RN selection is performed for both single hop and multi hop communication cases. Traffic based random deployment methods of RN, namely, lifetime-oriented deployment, and hybrid deployment, solve the issue of a short WSN lifetime and insufficient energy utilization. The trade-off between the lifetime extension and connectivity of SN in a WSN is considered in the performance analysis. The proposed method provides an efficient approach for the placement of RNs in a heterogeneous WSN.

In this paper, a systematic model for chemical oxygen demand (COD) removal using the ANAMMOX process was provided based on an experimental design. At first, the experimental data was collected from a combined biological aerobic/anaerobic reactor. For modelling and optimization of COD removal, the main parameters were considered, such as COD loading, ammonium, pH, and temperature. From the models,the optimum conditions were determined as COD 97.5 mg/L, ammonium concentration equal to 28.75 mg-N/L, pH 7.72 and temperature 31.3oC. Finally, the analysis of the optimum conditions, performed by the response surface method, predicted COD removal efficiency of 81.07% at the optimum condition.

Abstract\nLearner-oriented education is a spectrum that extends from the interaction between learner and teacher to pure learner-oriented education. This study uses a descriptive-analytical methodology to explore the views of the three main contributors of learner-oriented education, namely, Jean-Jacques Rousseau, John Dewey, and Jean Piaget. This study is an attempt to find the positions of these three personalities on learner-oriented education spectrum. The findings of this study show that all three personalities supported learner-oriented education and emphasized on its many attributes. These attributes provide learner the freedom of experimentation, interaction, and participation based on his needs, motivation, interest, and willingness that are driven by his talents and understanding. Learner-oriented education is like a color spectrum. It starts at the light end (A) and turns darker as education moves on the spectrum toward the other end (B). Each one of the three contributors has a position on this spectrum.
