Calibration of FDR sensor for irrigation automation

The theoretical basis of FDR sensors is often obscure for many scientists and field users. The present work introduces the concept and gives a first local calibration of two affordable VH400 Frequency Domain Reflectometry (FDR) sensors (running at 80 MG Hz) from Vegetronics, Utah, USA, enhanced by local electronic components. The two calibrations were carried out in August 2013 (35°C) and January 2014 (15°C) at Cairo University, Egypt. The full scale relationships of moisture content to mV and soil dielectric, among others, were all non-linear. However, for the narrower scale useful for soil moisture contents, from wilting point to saturation, were acceptably linear. The observed strong linearity in this narrower range makes the sensor practical for irrigation automated control. A famous power dielectric mixing-formula was used to estimate soil dielectric from three components mixing (minerals, water and air). Temperature decrease significantly increased soil dielectric values of the used sand sediments of the Nile bank that were adjusted to given moisture contents. Temperature dependence urges that the calibration process must be run at least four times per year for each soil material. Irrigation automation is particularly needed in for the partial fulfillment of irrigation control in order to tackle Egypt's augmenting water scarcity problems.
Inhibitory Effect of Some Carbazides on Corrosion of Aluminium in Hydrochloric Acid and Sodium Hydroxide Solutions
The dissolution of aluminium in hydrochloric acid and sodium hydroxide solutions in the presence of semicarbazide, thiosemicar- bazide and sym.dipheny1carbazide as corrosion inhibitors has been studied using thermometric, weight-loss and polarization methods. The three methods gave consistent results. The higher inhibition efficiency of these compounds in acidic than in alkaline madia may be due to the less negative potential of aluminium in hydrochloric acid solution, favouring adsorption of the additive.The adsorption of these compounds were found to obey Frurnkin adsorption isotherm. Cathodic polarization measurements showed that these com- pounds are cathodic inhibitors and their adsorption in the double layer does not change the mechanism of the hydrogen evolution reaction. The results are analysed in terms of both molecular and cationic adsorption.
Isn’t evolution science, and creation just a religious belief?
Creationist scientists don’t have all the answers
Why does it matter?
But how do we know that Genesis was meant to tell us that things were really made in six Earth-rotation days—couldn’t there be some other meaning?
Do the fossils show evolution?

مادة 1- في الله
نؤمن بأنه يوجد إله واحد، حي، حقيقي، روح ذات، واجب الوجود، سرمدي، غير متغير، خالق الكون، وحافظه، وضابطه. اله غير محدود في المحبة والرحمة والقداسة. والبر والعدل والحق والحكمة والقدرة.
نؤمن بأن الإله الواحد كائن في ثلاثة أقانيم الاَب والابن والروح القدس وأن هؤلاء الأقانيم جوهر واحد متساوون في القوة والمجد.
مادة 8- في خطية الإنسان
نؤمن بأن اَدم أبانا الأول خلق بلا خطية، ووعد بالحياة الأبدية على شرط الطاعة الكاملة إلى حين تحت قصاص الموت الجسدي والروحي إذا عصى.
وأنَّ اَدم بصفة كونه أبًا للجنس البشري تعين نائبًا عنهم. وأنَّه تعدي الوصية الإلهية مجربًا من إبليس فسقط بتعديه من حالته الأصلية حالة القداسة والشركة مع الله وصار عبدًا للخطية. وأنَّه بسبب خطيته وقع تحت الدينونة جميع البشر المتناسلين منه تناسلاً طبيعيًا ويولدون بطبيعة خاطئة بعيدة عن الله منها تصدر جميع الخطايا الفعلية. وإنَّه ليس في طاقة احد أن يخلص نفسه من حالة الجرم والفساد هذه.
معنى كلمة «ملائكة» في الكتاب المقدس؟
* معناها الأول واحدٌ في اللغات العبرية واليونانية والعربية وهو «رسول». واستُعملت في الكتاب المقدس لكل ما يستخدمه الله لإجراء مقاصده وإعلان ذاته وقوته، فجاءت فيه بمعنى «رسول عادي» (أي 1: 4 و1صم 11: 3 ولو 7: 24 و9: 52). وجاءت بمعنى «نبي» (إش 42: 19 وحج 1: 13 وملا 3: 1) وبمعنى «كاهن» (ملا 2: 7) وبمعنى «خادم العهد الجديد» (رؤ 1: 20). واستُعملت أيضاً لغير العاقل كعمود السحاب (خر 14: 19) والرياح (مز 104: 4). وسُمّي الأقنوم الثاني من الثالوث الأقدس «ملاك حضرته» و«ملاك العهد» (إش 63: 9 وملا 3: 1). وسُمّيت الأوبئة «ملائكة أشرار» (مز 78: 49) ودعا بولس الشوكة في جسده «ملاك الشيطان» (2كو 12: 7). ولكن كلمة «ملاك» اشتهرت باستعمالها للأرواح السماوية الذين يستخدمهم الله ليُجروا إرادته (مت 25: 31) فعُرفوا باسم «ملائكة الله»

مادة 72- قراءة الكتاب المقدس
قراءة الكتاب المقدس عنصر جوهري في العبادة الجمهورية. ويجب أنْ يكون لها مكان في كل خدمة. وأهمية هذه الفريضة تتطلب استعداد القسيس للقيام بممارستها بواسطة المطالعة والصلاة. وينبغي أنْ تُقرأ الكلمة بالاحترام، والتفكر، بكيفية تعبر بوضوح عن رسالة الروح، ويمكن إدخال قراءة الكتاب بالتبادل في الجزء الخشوعي من العبادة الجمهورية بكيفية نافعة للشعب.
صرخ الاعمى ابن طيمــا
يا يســوع ارحم فتــــاك
نال غيرى منــك بُـــرءاً
فــأعــن ضعفــى كــذاك
الجموع انتهرته
غضباً وهو يزيد
فدعاه الرب اقبل
ثًم سلنى ما تريد
لم يُرد مالاً سيفنـى
منه مع فقر ٍعـــلاه
بل بَغى رحمـة ربً
ليس يعطيها سواه
قال أرجو نورَ عين ٍ
أنت تعطيها البصـر
أبصرت عيناه حالاً
فـاقتفـــاهُ وشكـــــر
هوذا اسمعه ينادى
بتسابيــح النشيـــد
انظروا يا أصدقائى
رحمة الفادى المجيد
ليتمــا كــل ضـريــــر ٍ
يعرف الشافى الوحيد
ويُــوافيــه ليُـعطــــىَ
بصـــراً مــن جديـــد
