۴۔ زہر رگوں میں اتارنا پڑتا ہے

زہر رگوں میںاتارنا پڑتا ہے

تپتے سورج کی کرنوں کے نوکیلے پتھر

فگار دن کے برہنہ سر پر برس رہے تھے

ریل کی پٹری کو کاٹتی ہوئی کہنہ سڑک پر

انبوہِ آدم رواں دواں

قریب ہی پُل کے نیچے بیٹھے دھوئیں میں پریشاں حال

اپنے وجود کو تلاشتے چند انسان

موت کی آغوش میں پلتے ہوئے

دشت نما چہروں پر بے خوابی کی جھریاں

بد قسمتی کی دھول میں اٹے ہوئے بال

بوسیدہ پیراہن سے جھانکتا استخواں

آنکھوں میں خمارِ آشفتگی

جس میں ٹھکرائے جانے کا غمِ جاوداں پنہاں

 اس ہجومِ آشفتگاں سے ایک ژولیدہ مو

اپنی رگوں میں زہر اتارنے لگتا ہے

 زندگی بے اختیار چیخنے لگتی ہے

اے دشمنِ جاں یہ کیا۔۔۔؟

آشفتہ نوا گویا ہوا

سن اے زندگی!

’’خدا نے فقط تجھے عطا کر کے

بدلے میں مجھ سے کیا کچھ نہیں چھینا

اُس کے بے اماں جہان میں

رشتے بکتے ہیں

جذبات کا بیوپار ہوتا ہے

محبت بھیک مانگتی، تلوے چاٹتی ہے

جھوٹ مسکراتا ہے

سچ دریوزہ گر ہے

ہر کوئی نفرت کا خریدار ہے

اپنے بیگانے ہیں

یہ سب دیکھنے اور سہنے کے لیے

زہر رگوں میں اتارنا پڑتا ہے‘‘

Frequency of depression and anxiety among heart failure patients in a tertiary care hospital of Faisalabad, Pakistan Depression & anxiety among cardiac patients

Heart failure (HF) is a chronic illness with high prevalence and mortality, leading toeconomic burden ofhealth due to prolonged hospital stay and re-admissions. Failure to comprehend the importance of identifying mental illnesses could lead to explanations that why the morbidity and mortality of heart failure patients endure to be very high. Objective: To determine the frequency of anxiety and depression in heart failure patients. Methods: It is a descriptive cross sectional study including 323 CHF patients admitted to the Faisalabad Institute of Cardiology hospital, 250 were males and 73 were females, mean age was 54.1 ± 9.2 years having 70 years as maximum and 25 years as minimum.  Data was collected with the help of HADS questionnaire. Patients were interviewed for assessment of anxiety and depression. Data was analyzed using SPSS version 24. Mean and standard deviation was calculated for quantitative data and for qualitative data frequency and percentageswas calculated. To measure the association of anxiety and depression with age categories and gender, chi square test was used. P values less than and equal to 0.05 were taken as significant. Results: The results showed that 43% subjects had <11 score indicating no anxiety, 57% had >11score indicating anxiety. 45% subjects had<11 score indicating no depression, 55% had >11score indicating depression. Conclusions: The study concluded that frequency of depression and anxiety is high in congestive heart failure patients. Strategies are required to assess and diagnose these mental illnesses to establish early treatment which may foster multidisciplinary health care team approach and interventions that address the psychological burden.

Sliding Mode Framework Based Fault Tolerant Control for Air Path Actuators of a Turbocharged Diesel Engine

Exhaust emission control, especially in case of diesel engines, is a challenging re search problem as the emission regulating authorities place stringent protocols against emissions. The air management system of a diesel engine, that is fit ted with Variable Geometry Turbocharger (VGT) and Exhaust Gas Recirculation (EGR) actuators, is among the sub-systems, whose effective control ensures that emissions are kept to minimum. Both EGR and VGT sub-systems are located in the engine exhaust channel, hence, they are strongly coupled and exposed to high temperatures, un-burnt hydrocarbons and lubricants and thus prone to faults/cho king. One way to increase tolerance against faults is to have redundancy. Diesel engines do not have high number of identical actuators to preserve satisfactory operation, but, still have prospects for enhancing the reliability of these control loops by constructing algorithms, that are capable of performing online detection, diagnosis, estimation and compensation of faults. This research investigates the possible options for development of Fault Tolerant Control (FTC) schemes for coordinated control of air management system actuators of diesel engine. The dynamic nature of a control system and real time environment of Fault Detection and Isolation (FDI) and controller re-configuration requires FTC system to be capable of detecting, identifying and accommodating the faults as swiftly as pos sible. To meet the purpose, unified and systematic design techniques need to be developed to guarantee swift integration of FDI and FTC schemes, such that, the faults are handled in an early design phase by extending the control system with additional modules, i.e., FDI module. The model used in this research is a fully validated industrial scale Mean Value Model of a diesel engine that is equipped with VGT and EGR actuators. It has eight states and three control inputs. Two types of approaches i.e., passive FTC and unified FDI and FTC with further two algorithms of each have been proposed based on the sliding mode framework. The simulation results have shown that the proposed controllers can comfortably meet strict emission regulations even in the event of system faults. Specially fault de tection, estimation and compensation capability of unified approaches give them an edge over passive schemes.
