ڈینگی بخار قابلِ علاج ہے

ڈینگی بخار قابل علاج ہے
انسان جب سے منصہ شہود پر جلوہ گر ہوا ہے نشیب و فراز اور افراط و تفریط اس کا مقدر رہے ہیں۔ کہیں مسرتوں اور خوشیوں نے اس کا ساتھ دیا ہے تو کہیں غم و اندوہ کی بھیا نک وادیاں اس کا مسکن رہی ہیں،کبھی اس کے دل و دماغ خوش و خرم ہوتے ہیں اورکبھی افسردگی اور پژمردگی کی تپش اس کے سہانے خوابوں کو ملیا میٹ کر دیتی ہے، ان متنوع حالات سے انسان کو پالا پڑتا رہتا ہے۔ اور پھر حالات بدلتے رہتے ہیں اور مشکلات آسانیوں کا لباس زیب تن کر لیتی ہیں۔
رنج سے خوگر ہوا انساں تو مٹ جاتا ہے رنج
مشکلیں اتنی پڑیں مجھ پہ کہ آساں ہو گئیں
در دوالم کا ستایا ہوا انسان آج کل پھر ایک بیماری جس کوڈینگی بخار کے نام سے یاد کیا جاتا ہے کی لپیٹ میں ہے۔ یہ بخار 1775 میں افریقہ ،شمالی امریکہ اور ایشیاء میں پراسرار طور پرنمودار ہوا، اس بخار کا سبب مادہ مچھر ہوتی ہے جو کاٹتی ہے تو بخار ہو جاتا ہے۔ اس بخار کے پیراسائیٹس کو پلازموڈیم کہتے ہیں۔ یہ مادہ مچھر طلوع آفتاب اور غروب آفتاب کے وقت عروج و شباب پر ہوتی ہے اور پھر اس کے حملے شدید ہو جاتے ہیں۔ یہ مادہ مچھر ایک اعلیٰ ترین نسل سے منسوب کی جاتی ہے جو گندے پانی وغیرہ کو پسند نہیں کرتی بلکہ خوشنما، سرسبز پھولوں، پھلوں والے پودوں اور درختوں پر ڈیرہ جماتی ہے، اس کی حکومت زیادہ سے زیادہ دو ہفتے ہوتی ہے اور پھر ختم ہوجاتی ہے۔
قرآنِ پاک میں ارشادِ باری تعالیٰ ہے’’ کہ جب میں بیمار ہوتا ہوں تو وہ ( اللہ تعالیٰ) مجھے شفاء دیتا ہے‘‘ (پارہ-19 سورۃ الشعرائ) اسی طرح حدیث پاک میںارشاد رسالت مآب صلی اللہ علیہ و آلہٖ...

اسلام میں سد ذرائع کی اہمیت

The Islamic laws prevent us from the evil deeds. As well as, according to Shariah, it is permissible and sometimes even compulsory to save the believers from the actions that may lead them towards the banned activities. Therefore, the ruling of prohibition from these types of activities is called Sadd-e-Zaree’a. This is the principle extracted from the Quran and Sunnah. As Almighty Allah forbade the believers to say ‘Ra’ina’ because this word was used by Jews knowingly in a wrong manner with evil intentions, whereas, Muslims presented their requests by this same word in the highest court of The Holy Prophet (peace and blessings be upon him) for seeking easiness and relaxation in their concerned matters. As in Quran: O People who Believe, do not say (to the Prophet Mohammed- peace and blessings be upon him), " Ra’ina (Be considerate towards us)" but say, " Unzurna (Look mercifully upon us)", and listen attentively in the first place. [Baqarah 2: 104]. (To disrespect the Holy Prophet – peace and blessings be upon him – is blasphemy.) Another example by Hadith, in this regard, it is also evidenced by the good character of The Holy Prophet (peace and blessings be upon him) that sometimes He stopped himself intentionally from the permissible activities lest the common masses may involve in undesired activities on the basis of The Holy Prophet’s act. Concisely, keen consideration is required on rational basis when explaining the Shariah rulings of any matter. Otherwise, the beauty andbenefits of the Shariah may be lost. Consequently, to prevent from the future turmoil is actually the spirit of Sadd-e-Zaree’ah. As this is the actually basic need and prerequisite of Shariah. It saves and prevents its believers form expected turmoil. Therefore, if the risk of turmoil would trigger with committing the permissible activity it must be abandoned due to the risk of turmoil.

Rare Semileptonic B Meson Decays Beyond the Standard Model

In this thesis the exclusive rare semileptonic decays of B-mesons have been studied beyond the Standard ∗ Model. In particular the decays B → K1 (1270, 1400)l+ l− and Bc → Ds l+ l− are considered. These decays are induced by flavor changing neutral current (FCNC) transitions which at quark level arises as b → sl+ l− . In the Standard model these FCNC decays are not allowed at tree level but are allowed at loop level through Glashow-Iliopoulos-Maiani (GIM) mechanism. In addition they are also suppressed in the Standard Model due to their dependence on weak mixing angles of the quark flavor rotation matrix- the Cabibo Kobayashi Maskawa (CKM) matrix. These two circumstances make the FCNC decays relatively rare and hence are important to study physics beyond the Standard Model, commonly known as new physics. The main points of this thesis are: • The implications of the fourth generation quarks in the decay B → K1 (1270, 1400)l+ l− with l = μ, τ are studied, where the mass eigenstates K1 (1270) and K1 (1400) are mixture of 1 P1 and 3 P1 states with the mixing angle θK . In this context, we have studied various observables like branching ratio (BR), forward-backward asymmetry (AF B ) and longitudinal and transverse helicity fractions (fL,T ) of K1 meson in B → K1 l+ l− decays. To study these observables, we have used the Light Cone QCD sum rules form factors and set the mixing angle θK = −34◦ . It is noticed that the BR is suppressed for K1 (1400) as a final state meson compared to that of K1 (1270). Same is the case when the final state leptons are tauons rather than muons. In both the channels all of the above mentioned observables are quite sensitive to the fourth generation effects. Hence the measurements of these observables at LHC, for the above mentioned processes can serve as a good tool to investigate the indirect manifestations of the fourth generation quarks. • The same decay B → K1 (1270, 1400)l+ l− is also studied in the standard model (SM) and in universal extra dimension (UED) model. In this work we first relate the form factors through Ward identities and then express their normalization atq 2 = 0 in terms of a single constant g+ (0) which is extracted from the decays B → K1 (1270, 1400)γ. These form factors are then used to analyze the physical observables such as the branching ratio and the forward-backward asymmetry in the SM. This analysis is then extended to the UED model where the dependency of the above mentioned physical observables on the compactification radius R, the only unknown parameter in the UED model. It is shown that the zero position of the forward-backward asymmetry for the decay B → K1 (1270, 1400)μ+ μ− is sensitive to the UED model, therefore the zero position of the forward-backward asymmetry can serve as a handy tool to establish new physics predicted by the UED model. ∗ • The semileptonic Bc → Ds l+ l− (l = μ, τ ) decays have been studied in the Standard Model (SM) and in the Universal Extra Dimension (UED) model. In addition to the contribution from the Flavor Changing Neutral Current (FCNC) transitions the weak annihilation (WA) contribution is also important for this decay. It is found that the WA gives 6.7 times larger branching ratio ∗ than the penguin contribution for the decay Bc → Ds μ+ μ− . The contribution from the WA and FCNC transitions are parameterized in terms of the form factors. In this work we first relate the form factors through Ward identities and then express them in terms of g+ (0) which is extracted ∗ from the decay Bc → Ds γ through QCD sum rules approach. These form factors are then used to analyze the physical observables like branching ratio and helicity fractions of the final state ∗ Ds meson in the SM. This analysis is then extended to the UED model where the dependency of above mentioned physical observables depend on the compactification radius R. It is shown that ∗ the helicity fractions of Ds are sensitive to the UED model especially when we have muons as the final state lepton. This sensitivity is marked up at low q 2 region, irrespective of the choice of the form factors. It is hoped that in the next couple of years LHC will provide enough data on the ∗ Bc → Ds l+ l− channel, and then , these helicity fractions would serve as a useful tool to establish new physics predicted by the UED model.
