السفرجل

 ‏ هو فاكهة شتوية قريب من التفاح والكمثرى لذا تطعم شجرة السفرجل على شجرة التفاح أو شجرة الكمثرى فيتحسن المنتوج ويقاوم الأمراض التي يصاب بها السفرجل ويقضى على حالة تدود المنتوج.

Quince السفرجل بالإنجليزية 

 

عرف الأكديون هذه الثمرة وكانوا يسمونها بكلمة قريبة من اسمها الحالي. المنشأ الأصلي للسفرجل هو جنوب شرق آسيا وقد نجحت زراعته منطقة حوض البحر الأبيض المتوسط كما يزرع في سوريا والعراق وجنوب المملكة العربية السعودية ونيوزلندا.

 الاستعمالات

يستفاد من السفرجل ثمره وبذوره وذلك لإحتواء ثمار السفرجل على عدد من الفيتامينات خاصة فيتامين A و B كما تحتوي على 64% ماء و 7% سكر و0.9% بروتين و 0.3% مواد دهنية و 5% كبريت و 0.9% فوسفور و 14% كالسيوم و 2% كلور و 3% صودا و 0.13% بوتاسيوم كما تحتوي على مواد عفصية وبكتين واحماض وحوالي 20% ألياف, لذا للسفرجل استخدامات طبية أضافة لكونه غذاء جيد, فهو يستخدم كمادة مقبضة ضد الاسهال كما يستخدم لعلاج الجروح الملوثة وككمادات, وتستعمل بذوره لمعالجة آفات الصدر والرئتين.

يؤكل السفرجل نيا أو مطبوخا مع السكر على شكل مربى أو حلويات. ويؤكل مطبوخا مع دبس الرمان (سفرجلية). وللسفرجل أهمية طبية خاصة فمغلي الثمار يستعمل قطوراً في الأذن فيشفي جزءاً من صممه ويزيل الدوار، والثمار السكرية وقابضة، ويحضر من عصيرها شراب يضاف إلى الأدوية القابضة لتحليتها، وهو طارد للبلغم ومخفض للحرارة عند شرب العصير على الريق، ومقوي للقلب، وقابض للإسهال والنزيف.

والبذور غروية ويحضر منها مطبوخات توضع على الأورام فتحللها وتدخل في مركبات للقطرة، ومركبات تثبيت الشعر، وهي مدرة للبول وتمنع القيء عند شربها ومعطر للفم والمعدة. ومسكن للعطش، ومفيد للحوامل فأكله يحفظ الأجنة ويمنع الإجهاض، ويزيل خشونة الصوت ومزيل للسعال والربو وباستعماله دهاناً يقطع تأثير العرق الزائد. وهو عموماً كثمرة تستعمل مقوية للمعدة، ومنشط ومقوي عام وفاتح للشهية، ومنشط للكبد، ويشفي من اليرقان والصداع ويزيل حرقان البول، ويستعمل كعطر لآثار العرق، وبكثرة أكل الثمار تقوي البصر، وعند استعماله دهاناً يشفي الحكة والجرب، وعند مضغ لب الثمار فيشفي قروح الفم.

• التسكين والتقوية وفتح الشهية، وعلاج المعدة والكبد.

• يشفي الإسهال المزمن، ويقوي القلب، ويفيد المصابين بسل الأمعاء والصدر والنزيف المعدي والمعوي وانهيارات الرئة، ويقوي الهضم والأمعاء، ويمنع القيء ويفيد الأطفال والشيوخ، ويشفي من سيلان اللعاب ومن الزكام الشديد ومن سيلان المهبل وفقد الشهية، والعجز الكبدي.

• منقوعه يفيد أكثر من تناوله، وإذا أضيف مقدار ملعقة من مسحوق السفرجل إلى كمية من الأرز المسلوق في 250غرام من الماء أفاد الأطفال المصابين باضطرابات الهضم والمسلولين والنحيلين.

• ما يؤخذ منه هو عشرون غراماً ومن عصارته ثلاثون ولا ينبغي أكل جرمه ولا قطعه بالفولاذ فإنه يذهب ماءه سريعاً، وبذر السفرجل يستعمل مطلقاً ومغليه غسولاً في تشقق الجلد والجروح والبواسير والحروق، ومضافاً إلى غسولات العين في حال هيجانها والتهابها، يستعمل من الخارج في حالات هبوط المعي الغليظ والرحم والتشقق الشرجي والثديي وتشق الأيدي والأرجل من البرد والهيجانات بشكل غسولات وكمادات.

Gyroscope physics

Gyroscope physics is one of the most difficult concepts to understand in simple terms. When people see a spinning gyroscope precessing about an axis, the question is inevitably asked why that happens, since it goes against intuition. But as it turns out, there is a fairly straightforward way of understanding the physics of gyroscopes without using a lot of math.

But before I get into the details of that, it's a good idea to see how a gyroscope works (if you haven't already). Click on the link below to see a video of a toy gyroscope in action.

As you've probably noticed, a gyroscope can behave very similar to a spinning top. Gyroscope physics can therefore be applied directly to a spinning top.

To start off, let's illustrate a typical gyroscope using a schematic as shown below.

Where:

w_s is the constant angular velocity of the spinning wheel, in radians/second

w_p is the constant rate of precession, in radians/second

L is the length of the rod

r is the radius of the wheel

θ is the angle between the vertical and the rod (a constant)

As the wheel spins at a rate w_s, the gyroscope precesses at a rate w_pabout the pivot at the base (with θ constant).

The question is, why doesn't the gyroscope fall down due to gravity?!

The reason is this:

Due to the combined rotation w_s and w_p, the particles in the top half of the spinning wheel experience a component of acceleration a₁ normal to the wheel (with distribution as shown in the figure below), and the particles in the bottom half of the wheel experience a component of acceleration a₂ normal to the wheel in the opposite direction (with distribution as shown). Due to Newton's second law, this means that a net force F₁ must act on the particles in the top half of the wheel, and a net force F₂ must act on the particles in the bottom half of the wheel. These forces act in opposite directions. Therefore a clockwise torque M is needed to sustain these forces. The force of gravity pulling down on the gyroscope creates the necessary clockwise torque M.

In other words, due to the nature of the kinematics, the particles in the wheel experience acceleration in such a way that the force of gravity is able to maintain the angle θ of the gyroscope as it precesses. This is the most basic explanation behind the gyroscope physics.

As an analogy, consider a particle moving around in a circle at a constant velocity. The acceleration of the particle is towards the center of the circle (centripetal acceleration), which is perpendicular to the velocity of the particle (tangent to the circle). This may seem counter-intuitive, but the lesson here is that the acceleration of an object can act in a direction that is very different from the direction of motion. This can result in some interesting physics, such as a gyroscope not falling over due to gravity as it precesses.

Now, since it takes a torque to change the orientation of a spinning wheel, an extension of this is that a stationary spinning wheel will tend to remain stationary, and will resist any attempt to change its orientation. This is why gyroscopes are commonly used in navigation, such as in boats and ships. They tend to remain level even if the boat or ship changes orientation (either by pitching or rolling). Such gyroscopes work by mounting a spinning wheel (powered by a motor) in a gimbal (metal frame). The spinning wheel is mounted in the gimbal so as to be free of external torque, therefore it tends to maintain its level orientation as the boat, or ship rocks. The figure below illustrates a gyroscope-gimbal unit.

So now that we have an intuitive "feel" for gyroscope physics, we can analyze it in full using a mathematical approach. We will hence determine the equation of motion for the gyroscope.

The 10 elite smartphones of 2010

With the rise of Android, the reboot of BlackBerry, and the redesigned iPhone, 2010 can rightly be called the year of the smartphone. After reviewing nearly all of the top devices, here is my countdown of the best devices of the year.

 

10. BlackBerry Torch

BlackBerry came under intense pressure in 2010 from the rapid growth of iPhone and Android. The smartphone incumbent fired back with the release of the BlackBerry 6 OS and a new form factor with a slide-down keyboard in the BlackBerry Torch. The device is a bit underpowered, the OS isn't a huge step forward, and overall it hasn't been enough to stem the losses to Apple and Google. But, there are still a lot of BlackBerry fans out there — not to mention all of the enterprises locked into BlackBerry — and for them, the Torch is now the pre-eminent device on the market.

9. Motorola Droid 2

This shows how much progress the smartphone market has made in one year. Last year, I would have ranked the original Motorola Droid and the Apple iPhone 3GS as the two best smartphones on the market. This year, the Droid got a very nice upgrade but still struggled to make the top 10. Still, due to its increased specs, solid build quality, and very usable form factor, the Droid 2 belongs on this list. Also, don't miss its cousins, the Droid Pro and the Droid 2 Global.

8. HTC Incredible

With much the same innards as the Google Nexus One (although not nearly as strong of a build quality), the HTC Incredible was a consolation prize for those who had been salivating for the Nexus One on Verizon. Unfortunately, Google and Verizon pulled the plug on those plans and instead HTC offered the Incredible through Verizon with the traditional two-year contract. The Incredible did get one thing that the Nexus One didn't have: HTC's Sense UI. Some viewed that as a bonus over the stock Android OS on the Nexus One, while others saw it as a detractor.

7. Samsung Focus

Microsoft finally got itself back in the smartphone game in 2010 with the launch of Windows Phone 7, and the first widely-available WP7 device was the Samsung Focus, which didn't disappoint. The Focus sported nice hardware specs in an attractive, futuristic form factor (albeit with a lot of plastic, similar to the Galaxy S). And, Windows Phone 7 offered a new take on smartphone UI that is a little but more polished and fluid than Android or BlackBerry, although not quite as finished as the iPhone.

6. Motorola Droid X

Verizon Wireless went all-in on Android in 2010, launching a steady stream of new Android-powered devices throughout the year and replacing BlackBerry with Android as its primary smartphone platform. The Droid X served as Verizon's flagship Android phone, with its huge screen, 8MP camera, enterprise-class hardware, and extensive list of high-end features.

5. HTC Desire

While the HTC Incredible had the same guts as the Nexus One but a much different outer shell, the HTC Desire had similar internals and an outer shell that closely resembled the high quality metal casing on the Nexus One. The Desire quickly became one of the most popular smartphones in Europe and Australia by mid-2010 and has spread to other carriers through the globe since then. Along with the Nexus One and the iPhone 4, the Desire feels like the most substantial and high quality smartphone on the market. You should also keep an eye on the HTC Desire HD and the HTC Desire Z.

4. Samsung Galaxy S

Samsung joined the Android movement with all guns blazing in the middle of 2010 by releasing its line of Galaxy S smartphones in a variety of different form factors (and a confusing array of product names) on all four US wireless carriers and a fleet of international carriers. In the US, the Samsung Vibrant and the Samsung Epic 4G were the most impressive of the Galaxy S phones, but all of the models across the globe have same technology base and generally provide a very good Android experience.

3. Google Nexus One

The first big smartphone of 2010 was the Google Nexus One, launched just after the new year and right before CES 2010. As a product, the long-rumored "Google Phone" wasn't a disappointment. It had excellent build quality (developed by HTC) and ran the stock Android OS, which got all of the latest Android updates directly from Google. However, the phone failed in its larger mission of moving the US telecom market toward the European model of being able to buy phones and wireless service separately. The Nexus One was sold as an unlocked device at full price ($500) through Google's online store. Google was not well prepared to handle customer service and didn't give US consumers enough time to warm up to the idea of buying a full price device. It also never released the promised CDMA version of the Nexus One. Eventually, Google abandoned the product altogether and replaced it in December with the Nexus S, built by Samsung and available under traditional contract with T-Mobile.

2. HTC EVO 4G

The premier Android device of 2010 was the HTC EVO 4G. It was the first major smartphone to break the 4-inch screen barrier. It was the first 4G smartphone in the US. It was the first major smartphone with an 8.0 megapixel camera. It was the first major smartphone to feature a kickstand (for video viewing). I pejoratively called it the "Hummer of smartphones" because of its massive size and the fact that it's such as battery hog, but there's no arguing that the EVO 4G stretched the boundaries of what was possible in a smartphone and forced all of its competitors to play catch-up.

1. Apple iPhone 4

With all of the momentum that was gathering around Android during the first half of 2010, Apple's iPhone 3GS was starting to look pretty stale by mid-year — especially since it was only a slight upgrade over the iPhone 3G from 2008. Then, Apple unveiled iOS4 and the iPhone 4 and launched itself back to the head of the class with top-quality hardware and a software experience that still outpaces all of its rivals in terms of ease of use, responsiveness, polish, and third-party software. The iPhone 4 antenna problem, which was more severe than Apple acknowledged but a lot less severe than the tech press portrayed it, was a wart for the iPhone 4. It also still lacks the widget capability of Android (and now Windows Phone 7). But, overall, the iPhone 4 remains the gold standard of the smartphone market

Ear Structure

The sound vibrations enter the ear, guided by the pina. These vibrations cause the ear drum (a thin membrane) to vibrate. The vibrating ear drum make the three ear ossicles (the hammer, anvil and stirrup bones) to vibrate in turn. These ear ossicles amplify the sound so that even very quiet sounds can be heard. The eustation tube (which leads to the back of the mouth) helps keep the pressure of the middle ear constant. The ear ossicles in turn make the round window of the cochlea vibrate. The vibrations enter the cochlea which is a coiled fluid filled tube. Vibrations travel better in a liquid than in a gas. The vibrations which travel through the cochlea, make sensitive cells which line the tube vibrate. The cells are sensitive to a particular frequency of vibration and so a number of cells may vibrate when hearing a particular sound. The cells send impulses via the auditory nerve to the brain.

The semi-circular canals are fluid filled tubes. When our head moves the fluid in these canals stays still. Sensory cells which can be found in these canals sense the movement of fluid over them as the head moves. In this way the brain has an awareness of the position of the head.

Just thoughts ep. (1) Gift of life and death introduction indicators

The gift of God "the Spirit of life" given by birth and taken by death and its mystery  is based on the following outcome indicator: (God knows):
 The indicator comes on:
 1 - Degree of love, harmony and understanding between parents mainly - since they are partners, comitted to a contract witnessed by God and His angels - and also between close relatives and the surrounding community.

2 - the surrounding circumstances in that moment and at that place such as the need, poverty, nescience or disbelief, while on the other hand, wealth, ability, science and faith.
3 - Introductions or results of the work or deeds of parents.
 There are the souls of tormented and tormenting while on the other hand, the hearts of satisfied and successful , all according to the indicator above.
 And "How wonderful is the human Drudge - I say man and not the believer only - is the toil in this life and God created his children either to offer aid to him or increase the load on him or becomes on the enemy side.

According to the verse (O you who believe that some of your wives and some of your children might become your enemy, but beware of them and Explore the pardon and forgive the ...), and Mujahid said that "your wives and your children might be your enemy," i.e. severing ties of kinship or disobey his Lord. And God ensures that the believers of his existance and the existance of a message to deliver and to do in favor of the humanitarian, God will furnish thier life and death with the satisfaction and acceptance, Great Prophet Mohammad (PBUH) said ( How wonderful is the believer, for all his affairs are good, and not that of one only for the believer; if he has been given gifts he thanks; was good for him, or been given tough life he bears it patiently; and it was good for him). Narrated by Muslim 
 

خواطر طارئة (1) هبة الحياة بالولادة والقهر بالموت

 هبة الله روح الحياة وعطيته بالولادة وأخذه لهذه الروح وقهره للنفوس البشرية بالموت فيه سر وإعجاز بليغ يغفل عنه الكثير من السابقين واللاحقين، منها: (والله أعلم):

 

وجود مؤشر ينبع عن:

 

1- درجة الحب، التناغم والتفاهم  بين الوالدين بشكل رئيسي- كونهم شركاء بينهم عقد يشهد عليه الله وملائكته والنفوس الأخرى من نفس المحيط ونفس المجتمع - وبشكل فرعي المحيطين الأقارب والمجتمع. 

2-الظروف المحيطة زماناَ ومكاناَ مثل الحاجة ، الفقر ، العجز ، الجهل أو الكفر وبالمقابل الإكتفاء ، الغنى ، القدرة ، العلم أو الإيمان

3-مقدمات أعمال الوالدين أو جزاؤ هذه الأعمال و نتائجها.

 

فهناك نفوس معذَبة ومعذِبة وبالمقابل نفوس راضية مرضية وموفَقة وموفِقة وكلها تبعاً لهذا المؤشر علواً أو إنخفاضاً

 

وعجباً لأمر الإنسان الكادح -أقول الإنسان وليس المؤمن فقط- حسب قول الله الخالق تعالى في سورة البلد (ياأيها الإنسان إنك كادح إلى ربك كدحاً فملاقيه ... الآية) فهو يكدح في هذه الحياة ويخلق الله له من أبنائه إما أعواناً يعينوه على هذا الكدح و إما أعداءا يزيدون من عنائه وكدحه...

حسب قوله تعالى (يَأَيّهَا الّذِينَ آمَنُوَاْ إِنّ مِنْ أَزْوَاجِكُمْ وَأَوْلاَدِكُمْ عَدُوّاً لّكُمْ فَاحْذَرُوهُمْ وَإِن تَعْفُواْ وَتَصْفَحُواْ وَتَغْفِرُواْ فَإِنّ ...)
الآية وقال مجاهد " إن من أزواجكم وأولادكم عدوا لكم " قال يحمل الرجل على قطيعة الرحم أو معصية ربه فلا يستطيع الرجل مع حبه إلا أن يطيعه.

 

وتكفَل الله للنفوس المؤمنة بوجوده ووجود رسالة لهذه الإنسانية تعمل  لها بالرضى والقبول في طبيعة سير حياتها ومماتها حسب قول الحق سبحانه في سورة الحج: (إن الله يدافع عن الذين آمنوا إن الله لا يحب كل خوّان كفور) وقول الرسول الأعظم محمد (ص) ( عجبا لأمر المؤمن إن أمره كله خير ، وليس ذاك لأحد إلا للمؤمن ؛ إن أصابته سرّاء شكر ؛ فكان خيراً له ، وإن أصابته ضرّاء صبر ؛ فكان خيراً له) . رواه مسلم

 

وبالمقابل قال ابن رجب رحمه الله " خاتمة السوء تكون بسبب دسيسة باطنة للعبد لايطلع عليها الناس "

وقال بعضهم: ( كم من معصية في الخفاء منعني منها قوله تعالى : " ولمن خاف مقام ربه جنتان " )
