Introduction: Accurate postoperative alignment and implant positioning are determinant factors for successful total knee arthroplasty (TKA). Patient-specific template (PST) is a technique that uses computer technology for the planning, deigning and production of cutting guides. This study aims to compare PST to conventional technique in terms of mechanical axis alignment and component positioning. Patients and method: 109 TKA were performed for 78 patients in 2 groups. Group A included 69 conventional TKA in 55 patients and Group B included 40 patient-specific TKA in 23 patient. Postoperative long-film X-rays were done for all patients to observe the mechanical axis, anatomical axis, lateral distal femoral mechanical angle and medial proximal tibial angle. Results: No statistically significant difference was found between the two groups regarding alignment or component positioning. Conclusion: Both techniques have shown similar results in restoring the mechanical axis and alignment after TKA. However, PST had the advantages of reduced blood loss and shorter operative time.

This paper is concerned with the existence and upper semi-continuity of random attractors for the nonclassical diffusion equation with arbitrary polynomial growth nonlinearity and multiplicative noise in H1(Rn). First, we study the existence and uniqueness of solutions by a noise arising in a continuous random dynamical system and the asymptotic compactness is established by using uniform tail estimate technique, and then the existence of random attractors for the nonclassical diffusion equation with arbitrary polynomial growth nonlinearity. As a motivation of our results, we prove an existence and upper semi-continuity of random attractors with respect to the nonlinearity that enters the system together with the noise.

Two field experiments were carried out during growing seasons 2011 and 2012. It was executed in research farm of National Research Center in Nubaryia region, Egypt to study the effect of irrigation systems, fertigation rates by using the wastewater of fish farms “WWFF” in irrigation of potato. Study factors were irrigation systems (sprinkler irrigation system “SIS” and trickle irrigation system “TIS”), water quality (traditional irrigation water “TIW” and WWFF) and fertigation rates “FR” (20%, 40%, 60%, 80% and 100% NPK). The following parameters were studied to evaluate the effect of study factors: 1) Calculating the total amount of WWFF per season;2) Chemical and biological description of WWFF;3) Clogging ratio of emitters;4) Yield of potato;5) Irrigation water use efficiency of potato “IWUEpotato”. Statistical analysis indicated that, maximum values were obtained of yield under SIS × FR100% NPK × WWFF, also, there were no significant differences for yield values under the following conditions: SIS × FR100% NPK × WWFF > SIS × FR80% NPK × WWFF > SIS × FR60% NPK × WWFF > TIS × FR100% NPK × TIW. This means that, using WWFF in the irrigation can save at least 40% from mineral fertilizers and 100% from irrigation water under sprinkler irrigation system.

Different tillage practices are used for maize cropping in Libya. Yet, the effects of these practices on soil physical properties and maize growth and yield are not known. The objective of this study was to evaluate the effect of different tillage practices on soil physical properties and maize growth and yield in Libya. A field experiment was conducted in 2009 and repeated in 2010 using three tillage practices (conventional tillage (CT), ridge tillage (RT) and zero tillage (ZT)). Data about soil physical properties (penetration resistance (PR), bulk density (BD), total porosity (TP) and saturated hydraulic conductivity (Ks)) across soil depths, maize growth components (plant height, number of leaves, leaf area index and dry root weight) at 60, 75 and 125 days after planting, and maize yield (grain and stover) at harvest were collected and statistically analyzed in both years. To evaluate the effects of the tillage practices economically, the tillage operation cost and production cost were calculated. The results showed that at the surface layer (0 - 20 cm), CT had lower PR and lower BD, but higher TP and Ks compared to RT and ZT. At 20 - 40 cm and 40 - 60 cm depths, the lower PR and PD and higher TP and Ks were under ZT and RT compared to CT. All maize growth parameters at different times were highest for CT followed by RT and lowest for ZT. The CT practice presented the highest grain and stover yield followed by RT and ZT. However, harvest index was higher where ZT was applied. While tillage operation costs were the highest for CT followed by RT and ZT, the production costs were the highest for ZT followed by RT and CT. In general, the CT practice produced higher maize growth and yield, lower production cost, and higher tillage operation cost than those are planted using RT and ZT practices.

Objectives: Previous studies have demonstrated the role of inflammation in acute coronary syndrome (ACS). The neutrophil-to-lymphocyte ratio (NLR) was found to be a useful inflammatory marker for predicting adverse outcomes. We hypothesized that an elevated neutrophil-to-lymphocyte ratio would be associated with increased mortality in patients with acute coronary syndrome. Methods: The study consisted of 40 patients with acute coronary syndrome who were admitted to Cardiology Department—Menoufia University Hospitals. The primary endpoint was all-cause in-hospital as well as 30-day mortality, and the patients were divided into three tertiles according to their admission NLR results. Results: All-cause 30-day mortality in the three groups based on NLR was 0.0%, 7.7% and 28.6%, in the low-, middle- and high-NLR groups, respectively (P χ2 test). In a logistic regression analysis, including baseline demographic, clinical, and biochemical covariates, the neutrophil-to-lymphocyte ratio was an independent predictor of mortality (OR = 2.44, 95% CI = 1.185 - 5.007, P Conclusion: An elevated neutrophil-to-lymphocyte ratio (NLR), a simple, relatively inexpensive and universally available inflammatory marker, seems to be a predictor of 30-day mortality in patients with acute coronary syndrome.

Monitoring and assessment of agricultural land degradation is of vital importance for better land and water management planning and reclamation. It requires setting baseline information and basic analysis at specific time and space. About 33 geo-referenced soil sampling spots were selected in two agricultural production locations in the Kingdom of Bahrain to assess the status and preliminary causes of land degradation. Soil samples were taken from 13 sites in Diraz location while 19 samples were taken from Budayyi location. The samples were taken to 90 cm depth at 30 cm intervals. Standard procedures were followed to determine soil physiochemical properties. In addition, field observations on farm condition, distance from the sea, method of irrigation and irrigation water source were taken. Some of the soil samples were deliberately taken from outside the irrigated basins among trees compared with samples taken from inside the actively growing area for comparison. The results indicated that the salinity level was significantly (P < 0.001) higher at the 0-30 cm soil depth compared with 30-60 cm or 60-90 cm depths in both locations. The distance from the sea did not show clear correlation with surface soil salinity in Budayyi area compared with Diraz. Both locations showed significantly higher salinity levels on samples taken outside the actively growing areas compared with those taken from within. The effect is more prominent at the 0-30 cm depth. The observed variability on salinity levels may be attributed to farm management practices and deteriorating quality of ground water. Thus, agricultural land degradation in Bahrain cannot be attributed to ground water deterioration alone. The use of tertiary treated sewage water (TSE) may ease the pressure on ground water, but the pH of the TSE should be carefully monitored and managed with proper studies on leaching requirements to avoid further salinity complications.
