Stamina of a non-gasketed flange joint under combined internal pressure, axial and bending loading : an experimental study
No full textThe performance of a bolted flange joint is characterized mainly by its 'strength' and 'sealing capability'. A number of numerical and experimental studies have been conducted to study these characteristics under internal pressure loading conditions alone. However, limited work is found in the literature under conditions of combined internal pressure and axial loading. The effect of external, axial loading pressure being unknown, the optimal performance of the bolted flange joint cannot be achieved. Current design codes do not address the effects of axial loading on structural integrity and sealing ability. To study joint strength and sealing capability under combined loading conditions, an extensive experimental and numerical study of a non¬gasketed flange joint was carried out. Actual joint load capacity was determined at both design and test stages with the maximum external axial loading that can be applied for safe joint performance. Experimental and numerical results have been compared and overall joint performance and behaviour is discussed in detail

No full textal-Misbāh fī al-Nahw By Nāsir al-Dīn al-Mutarrizī al-Nahwī (d. 610/1213) A Critical Edition of the Text with the Life History of the Author
No full textNāsir al-Dīn al-Mutarrizī al-Nahwī (d.610/1213) was one of the most renowned figures in the field of Arabic Grammar. He has left an indelible mark on the world of Arabic language and literature. He is also known as the successor of al-Zamakhsharī.
He wrote a number of books but his al-Misbāh fī al-Nahw gained prominence at a level that no other book in this field could claim to achieve. For this reason, a great number of commentaries have been written in every age, of which the most famous are al-Daw and Khulāsat al-I‘rāb written by Tāj al-Dīn al-Isfrā’īnī and ‘Abd al- Karīm al-Tūsī (better known as Hājjī Bābā) respectively. Moreover, its translation into other languages also demonstrates its value as a useful book.
Although al-Misbāh has been edited on more than one occasion, the published editions do not fulfil the needs and requirements of modern academic research criteria. The basic aim of this thesis is to present this book with a current modern research style so that the students, teachers and ordinary readers of Arabic language and literature may benefit from this work.
This thesis is divided into two parts. The first part deals with the life history of the author and his other works. A brief note of the environment under which he grew up (generally referred to as the ‘Seljuk’ period) is also included in this part.
The second part consists of a text edition that deals with the derivation (Takhrīj) of syntactical issues together with the differing opinions of grammarians on syntactical/grammatical issues. This part also proffers the idiomatic English translation of al-Misbāh

Milk Supply Chain and Efficiency of Smallholder Dairy Producers in Pakistan
No full textMany developing countries are re-orienting their production and marketing systems by linking local agri-producers with organized supply chain networks and supermarkets to meet increasing consumer demands. However, the existing literature is silent on the effects of such integration on relative inefficiency of smallholder producers. This paper analyzes the effects of such supply chains using data from a natural experiment in the dairy sector of Pakistan. We study the impact of rural milk supply chain, known as milk district, on smallholder efficiency of commercial dairy producers by employing stochastic production frontier and technical inefficiency effects model using survey data of 800 dairy households. While location of dairy households in our sample is exogenously determined, building of milk supply chain indeed decreases technical inefficiency. We detect stronger power of milk district in further reducing technical inefficiency if the farms are located in remote areas, or if their size is relatively large. The advice to policy makers from these results conforms to the standard economic view that market competition leads to decreased levels of technical inefficiency of smallholder producers.supply chain, Production frontiers, Dairy efficiency, Food policy
Prevalence of Xerostomia in Diabetes Mellitus at lower Sindh.
No full textIntroduction: Xerostomia is a common problem in apparently normal as well as in ill individuals. Diabetes mellitus is a common endocrine disorder in which Xerostomia is complained frequently. Xerostomia contributes to altered eating habits and increase risk of dental caries and oral infection if there is inadequate blood glucose control. Factors affecting Xerostomia includes socioeconomic and medical condition, includes uncontrolled diabetes mellitus, presence of peripheral neuropathy, use of medications, gender and age.
Objective: To document the prevalence of Xerostomia among diabetic patients.
Methodology: This prospective, cross sectional study was conducted on known cases of Diabetes mellitus attending medical OPD at Muhammad Medical College, Mirpurkhas Sindh from March 2017 to August 2017. During this period 100 patients were included according to inclusion criteria. Demographic details were recorded. Fox questionnaire was filled in, the data collected was analyzed by SPSS version 22, and presented as number and percentage.
Result: Among100 patients; 37% were xerostomic and 63% were non xerostomic, age range of xerostomic was 50 ±7years and non xerostomic was 35 ±11 years. 21 females had Xerostomia and 29 had no Xerostomia .16 males were xerostomic, and 34 males were non xerostomic. Among xerostomic patients 15 were insulin dependent and 21 were non-insulin dependent. Where as in non xerostomic 22 were insulin dependent and 42 were non-insulin dependent. The mean duration of diabetes mellitus was 10 ±5 years in Xerostomic and it was 8 ±3 years in non xerostomic diabetes mellitus.
Conclusion: Xerostomia is common in elderly diabetics and in females and is dependent on glycemic control and duration of diabetes.
Key words: Xerostomia, Diabetes mellitus, Elderly and Duration of Diabetes Mellitus. 
FMEA of gasketed and non-gasketed bolted flanged pipe joints
No full textLimited work is available in the literature on the Failure Mode and Effects Analysis of bolted flanged pipe joints. From previous comparative reliability studies of both gasketed and non-gasketed bolted flanged pipe joints, generally it is found that both the joints types are of high integrity and perform well in excellent service under appropriate installation and maintenance conditions. However, based on certain factors better functional safety for non-gasketed joints can be achieved. All studies have been performed based on operational information and reported observations. This study reported herein presents a detailed failure mode and effects analysis (FMEA) in the light of industrial surveys, analysis, experimental work and subsequent observations in addition to previous studies. The aim of the study is to increase the reliability knowledge of the gasketed and non-gasketed flanged pipe joints and thereby to increase the basis for finding the optimal pipe connection based on surveys, observation and experimental studies performed

Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
