Considering simple and multiple relationships of organizational culture and its components with high school teachers’ effectiveness

The present study aimed to investigate simple and multiple relationships of organizational culture and its components (creativity and innovation, competitiveness, attention to group, attention to organizational members, attention to details, attention to result and output, and stability and durability) with teachers’ effectiveness in high schools of the city of Shavor. For this purpose, samples consisting of 184 female and male teachers of these schools were chosen by using stratified random sampling. To collect data, they were given the two realized questionnaires of organizational culture (using Robins and Denison’s pattern) and teachers’ effectiveness. Results of this study indicated that there was generally a relationship between organizational culture and teacher effectiveness. Furthermore, there was a significant relationship between components of organizational culture except “attention to details” and “attention to output and results” with teacher effectiveness. In addition, attention to group, creativity and innovation were respectively considered the best predictors of teacher effectiveness

Investigating the Impact of Nano-Calcined Halloysite on Concrete Durability under Chloride Attack

يشكل تأثير العوامل العدوانية، وخاصة الكلوريدات، على الهياكل الخرسانية تحديا كبيرا في مجال الهندسة. يؤدي وجود الكلوريدات إلى تآكل الخرسانة وتدهورها مما يؤثر على أدائها. تخترق الكلوريدات الخرسانة مما يؤدي إلى تدمير الطبقة الواقية حول حديد التسليح مما يؤدي إلى تآكل الفولاذ وتكوين الصدأ، يؤثر هذا التآكل سلبًا على قوة الارتباط بين الفولاذ والخرسانة ويمكن أن يسبب أيضًا تشققات على سطح الخرسانة، مما يقلل من متانتها, ولمواجهة هذا التحدي، تم إجراء دراسة بحثية لاستكشاف استخدام المواد النانوية، وتحديداً الهالويسايت المكلس النانوي، لتحسين أداء ومتانة الخرسانة. كان الهدف هو دراسة تأثير دمج الهالويسايت في الخرسانة على تغلغل الكلوريدات والتآكل اللاحق لقضبان حديد التسليح. تم فحص ثلاثة خلطات خرسانية مختلفة تحتوي على نسب متفاوتة من الهالويسيت (1.5%، 3%، 4.5%). وقام الباحثون بتقييم معدلات امتصاص الماء ومعاملات الهجرة لهذه الخلائط, بالإضافة إلى ذلك، تم استخدام تقنية التيار المسلط، حيث تم تطبيق تيار 14 مللي أمبير لمدة 26 يومًا لتسريع تآكل قضبان التسليح الفولاذية. أظهرت نتائج الدراسة فعالية دمج الهالويسيت في الخرسانة لتعزيز خواصه. حقق الخليط المحتوي على 3% و4.5% من الهالويسايت (CHNC) الأهداف المرجوة، مما أدى إلى تقليل امتصاص الماء بشكل كبير. على سبيل المثال، أظهر الخليط الذي يحتوي على %4.5 (CHNC) انخفاضًا بنسبة 42.99% في امتصاص الماء بعد 7 أيام. كما أدى هذا الانخفاض في امتصاص الماء إلى انخفاض كبير في معامل هجرة الكلوريدات واختراقها في الخرسانة. علاوة على ذلك، أدى إدراج 4.5% من الهالويسايت و25% من خبث الفرن العالي المحبب (GGBS) في الخليط إلى تحسين أداءه.The impact of aggressive agents, especially chlorides, on concrete structures is a significant challenge in the field of engineering. The presence of chlorides leads to corrosion and deterioration of concrete, affecting its performance. Chlorides penetrate the concrete, leading to the destruction of the protective layer around the reinforcing steel, which results in the corrosion of the steel and the formation of rust. This corrosion negatively affects the bond strength between the steel and the concrete and can also cause cracks on the concrete surface, reducing its durability. To address this challenge, a research study was conducted to explore the use of nanomaterials, specifically nano-calcined halloysite, to improve the performance and durability of concrete. The aim was to investigate the impact of incorporating halloysite in concrete on the penetration of chlorides and the subsequent corrosion of reinforcing steel rebars. Three different concrete mixtures containing varying percentages of halloysite (1.5%, 3%, and 4.5%) were examined. The researchers evaluated the water absorption rates and migration coefficients of these mixtures. Additionally, the impressed current technique was utilized, where a 14mA current was applied for 26 days to accelerate the corrosion of steel rebars. The results of the study demonstrated the effectiveness of incorporating halloysite in concrete to enhance its properties. The mixture containing 3% and 4.5% of halloysite (CHNC) achieved the desired objectives, significantly reducing water absorption. For example, the mixture with 4.5% CHNC showed a 42.99% reduction in water absorption after 7 days. This decrease in water absorption also led to a considerable decrease in the migration coefficient of chlorides and their penetration in the concrete. Furthermore, the inclusion of 4.5% halloysite and 25% ground granulated blast furnace slag (GGBS) in the mixture further improved its performance

The electrophysiological findings of sensory and motor parameters of median nerve including (latency, amplitude and conduction velocity) between patients and control groups all show highly significant difference (p <0.01)

Investigation of the Corrosion and Scaling Potentials of Raw and Treated Water and Its Effect on Concrete Tanks at Al-Tayyaraa Water Treatment Plant

تم إجراء هذه الدراسة لتقييم الامكانيات التآكلية وتكوين التكلس للمياه الخام والمعالجة  في محطة الطيارة لمعالجة المياه خلال فترة اثني عشر شهرا بدءا من يناير حتى ديسمبر 2016. تم النظر في ثلاثة مؤشرات للتآكل والقياس في هذه الدراسة بما في ذلك مؤشر ريزنار (Ryznar Index (RI))  ومؤشر لانجيلير للتشبع (Langelier Saturation Index (LSI)) والمؤشر العدواني (Aggressive Index (AI)). في هذا البحث تم قياس معاملات جودة المياه pH، Alk (Ca) ، درجة الحرارة، الكالسيوم متمثلا ﺒ (CaCO3)، و أخيرا المعامل TDS. واظهرت النتائج للمياه الخام ان قيم LSI  و RI  كانت على التوالي (0.14-0.504) و (0.03-0.4)  في حين كانت نتائج نفس المؤشرين للمياه المعالجة  هي (6.956 -7.62) و (7.02-7.7) على التوالي. وكانت نتائج المؤشر AI للمياه الخام والمياه المعالجة هي (11.77-12) و (11.67-11.948 ) على التوالي. وكشفت القيم المحسوبة  للمؤشر LSI أن المياه المعالجة والماء الخام كانت متوازنة أو ممكن تكون طبقة رقيقة جدا من الترسبات. أشارت قيم المؤشر RI إلى أن المياه الخام والمعالجة كانت مسببة للتآكل وأظهرت قيم المؤشر العدواني (AI) أن الماء كان  مسببا لتآكل معتدل وليس له تأثير واضح على الخزان الخرساني في محطات معالجة المياه.This study is conducted to evaluate corrosion and scaling potentials of raw and treated water at Al-Tayyaraa water treatment plant during a period of twelve months, starting from January to December 2016. Three indices of corrosion and scaling in this study are considered including Ryznar Index (RI), Langelier Saturation Index (LSI), and Aggressive Index (AI). Water quality parameters pH, Alk, (Ca), temperature, calcium as CaCO3, and (TDS) are measured. For raw water, the values of LSI and RI are (0.14-0.504) and (6.956 -7.62), respectively, whereas for treated water, the values of LSI and RI are (0.03-0.4) and (7.02-7.7), respectively. The values of AI are (11.77-12) for raw water and (11.67-11.948) for treated water. The calculated values of Langelier Saturation Index (LSI) reveal that the treated and raw water are balanced to some faint coating (light scale forming). The values of RI point that the raw and treated water are corrosive and values of aggressive index show that the water is moderate corrosion and no obvious effect on concrete tank at water treatment plants
