Application of Multiple Criteria Decision Models for Oilseed Crops in Pakistan’s Punjab
Pakistan is deficient in major food products. Self-sufficiency in food has virtually always been a major priority, because imports of wheat, edible oil, sugar, pulses and milk products put a massive burden on the balance of payments for the country. The increase in the production of oilseed has been a priority goal of the agricultural development policy in Pakistan. The oilseed crops have been validated as alternative crops on several target locations of different agro-ecological zones [PARC (1990)]; but the success of this validation work in terms of their dissemination is very limited. The possibility of including these crops in well established systems needed to be well conceived. The selection of farming systems, which have the potential to adopt such crops, is a prerequisite to investigate the problems and prospects of oilseed crops. The emphasis of the study is, therefore, on the identification of typical farm situations where the oilseed crops can be evaluated for their potential inclusion in the cropping plans. A real decision-making environment in agriculture involves several objectives along with their explicit targets.
Role of Opposition Parties in Pakistani Democracy: A Case Study of United Democratic Front (UDF)
This study is an attempt to explore the contribution and role of opposition parties to strengthen democracy in Pakistan. It also investigates and snoops the opposition alliance resulted from the politics of United Democratic Front which was a Parliamentary opposition alliance from 1973-1976 during Zulfiqar Ali Bhutto (1928-1979) period. Furthermore, this alliance exhibited critical views, presented their constitutional demands and played pivotal role in constitution formation of 1973 in Pakistan. It also encapsulates the role of aforesaid parliamentary alliance in various other amendments during Bhutto Government. To explore the role of this parliamentary alliance further, UDF demonstrated resilience and put forward their critical views for the constructive, productive and active role in democratic, constitutional and political developments specifically in Bhutto regime. Bhutto’s chrisamatic leadership was exquisitely responsive and dealt them tactfully regarding the UDF and opposition’s demand related to constitutions and political issues in Pakistan politics. This research work presents a fact finding analysis regarding political reservations of opposition parties, depicts circumstances and various compulsions which necessitated the formation of UDF; its aims and objectives as well as political resistance of UDF to Bhutto’s policies, constitutional formationand in different other constitutional amendments under Bhutto’s rule
A Technique for Better Energy Management of Single-Stage Topology of Stand-Alone Photovoltaic System
This paper proposes a technique for energy managing of a stand-alone photovoltaic system. The proposed system employs a power processing inverter, which contains high PV voltage at the input to mitigate the magnitude of AC signal at the output, eliminating use of DC-DC converter and reduces the input capacitor size of PV array. To meet the power requirement of load and to maintain the maximum power point operation of PV array, battery bank is utilized with a bi-directional converter. An impedance model of the complete system is executed. Based on the model, the control architecture is designed which works in four modes: 1) if load demands > MPP of PV, additional current is extracted from the battery; 2) if load demands < MPP of PV array, extra current is given to the battery; 3) only load management is utilized since the battery bank is not available because of over-charging or under-charging; 4) if irradiation varies then first mode is used for load requirement. The technique is designed which guarantees the maximum power point tracking of PV system even without using any intermediate stage of DC-DC converter, hence making it single-stage, MPPT is achieved by effectively controlling bi-directional converter used for battery charging and discharging purpose. To ensure better utilization of dc voltage enhanced efficiency and low less harmonic distortion, sinusoidal PWM technique is used to drive the inverter. Simulation results are carried out for ensuring better energy management along with MPPT operation demonstrated under uniform operating conditions
Study of rare mesonic decays involving di-neutrinos in their final state
We have carried out phenomenological implication of R-parity violating
(\NEG% {R}_{p}) Minimal Supersymmetric Model (MSSM) via analyses of pure
leptonic() and semileptonic decays of
pseudo-scalar mesons(% ). These analyses involve
prediction of branching fraction of pure leptonic decays by using experimental
limits/bounds derived from the study of semileptonic decays on \NEG{R}_{p}
parameters. We have found, in general that \NEG{R}_{p} contribution dominates
over the SM contribution i.e., by a factor of for the semleptonic
decays of , for the pure leptonic decays of , while
\& in case of and respectively. This
demonstrates the role of \NEG{R}_{p} as a viable model for the study of NP
contribution in rare decays
Effectiveness of Mckenzie Traction and Exercises on Neck Pain Secondary to Upper Crossed Syndrome.
OBJECTIVES: To examine the effects of McKenzie traction and exercises on neck pain, cervical ranges, functional activities and posture secondary to upper crossed syndrome. METHODS: Randomized control trial was conducted on patient of neck pain secondary to upper crossed syndrome from physical therapy setups of Lahore and Sargodha in total six months. 120 patients of 20-60 years’ age group were allocated in two groups (experimental and control), both contained 60 respondents, both groups received neck pain exercises with TENS for eight weeks, weekly three times and McKenzie traction and exercises were additionally received by experimental group. Partakers were assessed after eight weeks of treatment. Oswestry questionnaire was used for assessment, reed co scale and goniometer parameters, was used. RESULTS: Collected data was analyzed in SPSS 20. Independent sample t-test was applied to compare mean of quantitative data at the end of treatment in both groups. Mean pre-treatment Oswestry disability score in general exercise group and McKenzie group was 60.37 and 56.82 respectively (with p-value > .05). Mean post treatment Oswestry disability score in general exercise group was 30.63 and in McKenzie group was 26.70 (with p-value.02). Mean pre-treatment flexion, extension, side flexion and rotation means in general group were 36.38, 47.10, 36.32, and 66.37 respectively whereas in McKenzie these values were 38.30, 45.47, 37.47 and 67.38 respectively (with p-value > .05). CONCLUSION: Both general exercises and McKenzie treatment improved neck pain secondary to upper crossed syndrome, however the McKenzie treatment stood significantly better than general exercise.

Composite split cord malformation associated with a dermal sinus tract, dermoid cyst, and epidural abscess: A case report and review of literature
Background: Split cord malformation (SCM) is typically present at a single level but rarely, may be present at multiple levels in the spinal cord and can be associated with a wide array of lesions such as myelomeningoceles, lipomas, teratomas, and dermal sinus tracts (DSTs).Case description: We describe a case of a 15-month-old female child who presented with high-grade fever and progressive motor weakness in the lower limbs. Magnetic resonance imaging revealed the presence of SCM along with an epidural abscess, DST, and dermoid cyst. The child underwent surgery for excision of DST along with removal of the dermoid cyst and drainage of epidural abscess. The postoperative course was uneventful. Elective repair of the SCM was performed 4 weeks later. The postoperative course was uneventful again.Conclusion: To the best of our knowledge, the combination of a composite SCM with a DST and dermoid cyst with associated epidural abscess has rarely been reported in literature
