The comparison of various gas turbine inlet aircooling methods for various ambient condition trough energy and exergy analysis

The strong influence of climate conditions on gas turbine behavior is well known. During the summer season the output of gas turbines falls to a value that is less than the rated output under high temperature conditions. Cooling the turbine inlet air can increase output power considerably, because cooled air is dense, giving the turbine a higher mass flow rate and resulting in increased turbine output and efficiency. This study is to use the energy and exergy analysis method to evaluate the air cooling method used for enhancing the gas turbine power plant. In addition, the effect of inlet air cooling method on the output power, exergy efficiency and exergy destruction have been analyzed. Also at the end of the paper the comparison of two mentioned methods has been investigated

Effect of Using Ginger Roots Powder and Pure Allicin in Fattening Awassi Lambs Rations on Productive Performance and the Accessory Cut Parts of Carcasses

   أُجري البحث بهدف دراسة تأثير إضافة الاليسين أو الزنجبيل أو خليطهما إلى علائق تسمين الحملان العواسية في الصفات الإنتاجية وبعض الأجزاء الثانوية للذبائح.     استعمل في البحث 28 حملاً عواسياً وزعت عشوائياً على أربعة معاملات متساوية كل معاملة احتوت 7 حملان ، غذيت الحملان على أربعة أنواع من العلائق التجريبية والتي كانت كالآتي: العليقة الأولى عليقة مركزة خالية من الإضافات الغذائية (سيطرة)، العليقة الثانية احتوت على الاليسين النقي بنسبة 3 كغم لكل طن علف مركز، العليقة الثالثة احتوت على مسحوق جذور الزنجبيل بنسبة 2 كغم لكل طن علف مركز أما العليقة الرابعة فقد احتوت على خليط من الاليسين (1.5 كغم/ طن علف مركز) ومسحوق جذور الزنجبيل (1كغم/ طن علف مركز).    غذيت الحملان بطريقة التغذية الجماعية ولمدة 91 يوماً ودرست الصفات الإنتاجية والتي تضمنت الزيادات الوزنية الكلية واليومية ومعامل التحويل الغذائي وكميات العلف المستهلك من الخشن والمركز.    ذبح 12 حملاً من حملان التجربة بواقع ثلاثة حملان من كل معاملة لغرض تسجيل أوزان الأجزاء الثانوية للذبيحة والتي شملت الرأس والجلد والأرجل.    أشارت نتائج البحث إلى عدم وجود فروقات معنوية بين المعاملات المدروسة للأوزان الابتدائية والنهائية والزيادات الوزنية اليومية والكلية، ولم تلاحظ فروقات معنوية في كميات العلف المركز والخشن المستهلك ومعامل التحويل الغذائي، و أوضحت نتائج البحث أيضاً عدم وجود فروقات معنوية في صفة الرأس للذبائح بين المعاملات المختلفة بينما كانت الفروقات معنوية (P<0.05) لصفة الجلد والأرجل.The research has been conducted to investigate the effect of ginger roots powder with allicin in the fattening of Awassi lambs rations with its effect on productive traits as well as the secondary cuts parts of carcasses. A total number of 28 Awassi lambs were used in the research , those lambs were randomly distributed into 7 treatments, lambs fed on 4 experimental rations as follows the first ration was concentrated ration without any supplement (control), the second ration supplemented with 3.0 kg/ton of allicin, the third ration supplemented with 2.0 kg/ton ginger powder, the fourth ration supplemented with a combination of allicin (1.5 kg /ton) and ginger powder (1.0 kg/ton). Lambs fed by group feeding along with the experiment which had been lasted 91 days. The productive traits were studied such as a daily and total weight gain as well as feed conversion ratio and the consumed quantity of concentrated and rough feed. Twenty-one lambs were slaughtered (three lambs for each treatment)  to study the secondary cuts parts of the carcasses. Results revealed no significant differences among treatments in the initial and final weights and daily and total weight gains.  There were no significant differences in the consumed feed among treatments and feed conversion ratio. Results indicated also nonsignificant differences in weights of the head among treatments. Meanwhile, there were significant differences (P<0.05) in skin and legs weights among treatments. &nbsp

Penerapan Model Pembelajaran Berdasarkan Masalah ( Pbm ) Untuk Meningkatkan Hasil Belajar IPS Siswa Kelas IV SD Negeri 18 Babussalam Kecamatan Mandau

This research is motivated by the lack of student learning outcomes IPS, it can be seen from the results of social research Elementary School fourth grade students Babussalam 18, with the average value of the class 63.60. Therefore, the researchers provide an alternative learning for the implementation of the model Problem Based Learning (PBM) in the fourth grade SDN 18 Babussalam. This study aims to improve learning outcomes IPS fourth grade students of SD Negeri 18 Babussalam Implementation of Problem Based Learning Model (PBM). Design research is action research (PTK) with two cycles. Based on the analysis of research data after applying the model of Problem Based Learning (PBM), the average percentage of activity the teachers in the first cycle of 82.5% increased to 92.5% in the second cycle. The average percentage of student activity also increased, namely 77.5% in the first cycle increased to 87.5% in the second cycle. learning outcomes in basic score with the average value of 63.60 and the first cycle of students increased by an average value of 72.66 with an increasing percentage of classroom learning achievement of 12.46% and the percentage of students who completed 76.66%, and the second cycle increased again to an average of 77.33 with the percentage improvement class learning outcomes 13.73% and the percentage of students who completed 83.33%. These results suggest that application of the model of Problem Based Learning (PBM) can improve learning outcomes IPS fourth grade students of SD Negeri 18 Babussala
