المبحث الأول: ممیزات أشعار نازك الملائکۃ
یوجد في شعر نازک الملائکۃ ’’القیمۃ الفعلیۃ‘‘ وھذہ القیمۃ لا تتمثل في أن شعرھا قابل للتقلید أو أخذہ کنموذج مثالي یقتدي بہ من بعدھا الآخرون، ولکن المیزۃ الممتازہ في شعرھا بأن لدیھا القدرۃ علی التحرر من العاطفۃ والرومانسیۃ وما إلی ذلک۔
ویذکر شوقي بزیغ في مجلۃ العدد’’ وقد تکون تربیۃ نازک المحافظۃ ونشأتھا في أسرہ متعلقۃ بأھداب القیم الموروثۃ ھي من بین العوامل التي دفعتھا إلی احترام العادات والتقالید المحیطۃ لھا من کل جانب، وعلی الرغم من إقامتھا الطویلۃ في أمریکا فنحن لا نلمع في شعرھا ما یشي بالتجرؤ علی الأعراف السائدۃ وتجاوز المحظورات لابل إننا نکاد لا نعرف شيئاً عن حیاتھا الخاصۃ أو عن علاقاتھا العاطفیۃ التي سبقت الزواج‘‘[1]۔
فیذکر شوقي بزیغ لا بد من الاعتراف بأن نازک، بسبب النشأۃ أو الخوف أو مکانۃ المرأۃ العربیۃ أو بعض الظروف الاجتماعیۃ لم تسمح للشاعرۃ أن تتعمق في الحداثۃ أو بما تکون الحالۃ الاجتماعیۃ أو مکانتھا أو عادات البيئة العربیۃ والواقع العربي والعراقي بوجہ خاص وقد تکون ھذہ الظروف نفسھا ھي التي لونت معظم قصائدھا بلون الحزن والألم ، وجعلت الموت یحتل موقعاً متعلقاً في نظرتھا، ولکن الجانب الإیجابي یحجب علی حزنھا ویظھر الجانب الآخر وھي قدرتھا علی تحویل حزنھا إلی مادۃ للتأمل الھادئ والتبصر العمیق والتعجب في الحیاۃ وفي أحوال النفس وأسرارھا، وھو ما تکمن ملاحظتہ في قصائدھا مثل "أجراس سوداء" و "مرثیۃ یوم تامہ" و "الشخص الثاني" و "الخیط المشدود في شجرۃ السرو" وغیرھا[2]۔ نلاحظ أن معظم قصائدھا ملون بلون الحزن والألم وقد تکون أسبابھا لیست ظاھرۃ ولکن ربما یکون ھناک سر مختبيئ في قلب الشاعرہ، وھي لا تستطیع إظھارہ وذلک بسبب حالة من الحالات أو بسبب ظروف معینۃ ویتضح ألمھا الداخلي ونظرتھا الی الوجود والأشیاء، بأنھا فانیة...
COVID 19 is a recent and global pandemic. Preventive medicine is not very popular in Pakistan. With the limited resources, an average Pakistani would spend on a medical treatment rather than on a preventive drug. In Pakistan, booster shots are recently made available only to those who can pay for the cost of the vaccine. A Utilitarian approach has been adopted at various levels since the pandemic emerged by health care organizations and the government. The purpose was to maximize the benefits and minimize the risk of harm. It is the need of the hour to think about health equity and justice in a pluralistic way and refrain from initiating booster shots for elite of a resource-poor country. This pandemic will never end if a maximum number of people are not vaccinated in each country. This is only possible if there is an equitable distribution of vaccines.
Present day low quantity, high variety, and make-to-order manufacturing scenario demands concurrent product development. Major attributes required for concurrent product development are: seamless and bi-directional data flow among design, manufacturing and quality control cycles. This thesis documents research in to the field of generic feature based design and manufacturing process planning of discrete sheet metal bend parts. In this context sheet metal forming is subjected to various variations, due to which state of the art in sheet metal pressbrake forming is still recognized as a separate and vague island of automation. Formal integration of standards and specifications is required for knowledge retrieval, generated during manufacturing phase. Sheet metal pressbrake forming is subjected to various process and material variations and ultimate shape of a 3D formed part depends upon the capability and health of the equipment of a native manufacturing setup. Process planning and process parameters are optimized by altering some of the design attributes. Valuable knowledge generated during this activity is lost and is not communicated back to the upstream design stage. This research highlights several issues regarding feature based design and manufacturing of discrete sheet metal parts. Contemporary standards STEP (STandard for Exchange of Product data) and STEP-NC ( STandard for Exchange of Product data for Numerical Control ) are utilized to formulate a framework for feature based design and manufacturing of discrete sheet metal parts augmented with the capability of knowledge retrieval. Major contribution of this research is a proposed framework for feature based design and manufacturing of discrete sheet metal parts developed on the basis of STEP and STEP-NC standards. It outputs a generic feature based manufacturing process plan that could be mapped and optimized according to the capabilities of a native manufacturing environment. In the proposed framework STEP enabled manufacturing process plan communicates generic information independent of any vendor specific detailing which is mostly based on rigid data formats such as ISO 6983. Functional requirements of the framework are categorized into three independent modules for the CNC pressbrake process control unit: 3 (1) Feature based design development of discrete sheet metal parts (2) Generic feature based process planning of discrete sheet metal parts (3) Offline process plan optimization according to the capabilities of a native manufacturing environment. The framework was validated through experimentation on a CNC pressbrake with 3-axis back gauge locating capabilities. STEP & STEP-NC compliant framework for feature based design and manufacturing of discrete sheet metal parts provides a powerful tool for generating generic process plans and knowledge retrieval generated during final process plan optimization and execution. Prototype system using ST-Developer® Visual C++ libraries is developed to demonstrate the functionality of the proposed framework.
