    Get PDF
    The National Internal Security Policy (NISP) initiated ten months before the Peshawar Army Public School (APS) assault in Dec 2014, when an all Parties meeting was directed and chaired by the PM Nawaz Sharif including the top army brass, pronounced an inclusion of twenty Points of National Action Plan (NAP) to impede the terroristic and extremist activities in the country. Recently, through a thought-process, the detailed NAP fundamentally redesigned and included two more points while setting the motives of the NISP: the establishment of Army courts to manage the postponed trials of “jet black” terrorists and death penalty reinforcement for the attackers of (APS) and other has terrorists’ activities to curb radicalism and militancy in the state. In view of this scenario, this paper attempts to propose some reflections on what are the policy management challenges in implementation of NISP and NAP? What are the deficiencies of state’s regulatory authorities which plague the effective implementation of NISP in Pakistan? What are the perils and prospects of NAP? And what are the achievements of NAP thus far? Keywords: National Internal Security Policy, National Action Plan, National Counter Terrorism Authority

    Controllability Backbone in Networks

    Full text link
    This paper studies the controllability backbone problem in dynamical networks defined over graphs. The main idea of the controllability backbone is to identify a small subset of edges in a given network such that any subnetwork containing those edges/links has at least the same network controllability as the original network while assuming the same set of input/leader vertices. We consider the strong structural controllability (SSC) in our work, which is useful but computationally challenging. Thus, we utilize two lower bounds on the network's SSC based on the zero forcing notion and graph distances. We provide algorithms to compute controllability backbones while preserving these lower bounds. We thoroughly analyze the proposed algorithms and compute the number of edges in the controllability backbones. Finally, we compare and numerically evaluate our methods on random graphs.Comment: Accepted in 62nd IEEE Conference on Decision and Control, Dec. 13-15, 2023, Singapor

    The late Cretaceous Kawagarh Formation has been investigated in terms of field observation, and petrographic analysis, to understand the petrography and its impact on the geotechnical properties. The Kawagarh Formation is well exposed among the upper Indus Basin, and has been studied by various workers in different aspects. Kawagarh Formationexposed in Kahi section of Nizampur Basin has been selected in this study to know the behavior of carbonate rocks for engineering purposes. Lithologically, this formation is composed of thick to medium bedded, highly fractured limestone, marls, and dolomitic limestone which has undertaken diagenetic alteration including dolomite, calcite veins, and stylolites. Followed by petrographic analysis which reveals that the Kawagarh limestone is mostly fossiliferouscomprised of a large number of planktonic foraminifera fossils like Globotruncana Hilli and Globotruncana Linneana fossils. Furthermore, to know the impact of petrographic minerals on engineering behavior, mechanical properties in terms of uniaxial compressive strength (UCS) and uniaxial tensile strength (UTS) were also computed by using a universal testing machine (UTM). The resultant mechanical values lie in the strong compressive strength and suggest their usage for various construction purposes. Aggregate degradation tests including water absorption, specific gravity, aggregate impact value, Los angles abrasion, and soundness was also computed according to the International standard organization, ASTM (American Society for testing materials) and British standard. The aggregate values of the Cretaceous Kawagarh Formation are within the defined standard limits and can be used as an aggregate source for different construction engineering projects

    Economics of date palm production and its constraints in District Kech, (Balochistan) was analyzed during 2012-13 using 60 date palm producers; while a good number of market agents/middlemen were also included to analyze date palm marketing. The data indicated that Turbat and Panjgoor are the districts of excellence for their high quality and remarkable date palm production; and Begum Jangi dominates in area and production, followed by Halini, Hussaini, Goknah, Dishtri, Konzenabad, Muzwati, Pashpag, Shakri and Washakar. The total estimated costs on date palm production were Rs. 225271.31/hectare which included Rs. 50903 land inputs, Rs. 66468 initial development of orchard, Rs. 76111 operational costs and Rs. 31789.31 marketing costs. Among initial orchard development costs, purchase of date palm suckers was the item of highest cost, followed by the farmyard manure and ploughing charges. The total land inputs including land rent and land tax accumulated to Rs. 50903/hectare. Among marketing costs the transportation charges were the highest amount of costs. The overall average date palm fruit yield was estimated at 77.29 maunds per hectare. The date palm yield was higher in trees aging 10-20 years; while Washakar variety fetched highest sale price, followed by Begum Jangi, Konzenabad and Goknah, while hydrated form of dates (Chhuhara) is mostly prepared from Halini variety. The income from date palm per hectare was estimated at Rs. 286745.90 against total costs Rs. 225271.31 resulting net returns of 61474.59 per hectare, resulting cost: benefit ratio of 1:1.27. The marketing analysis indicated that total price spread was Rs. 3500.00 per maund while the product reached in the hands of ultimate consumer. The middlemen (Wholesalers and commission agents) and retailer earned marketing margins of 31.68 and 24.69%, net margin 75.23 and 85.34 %, markup 46.36 and 32.78 %. The retailer shared 42.10 paisa of the consumer’s rupee, middlemen (wholesaler and commission agents) 35.86 paisa; while the producer shared the lowest (22.04 paisa) of the consumer’s rupee. The retailer earned 5.82 rupees (CBR=1:5.82), middlemen (wholesaler and commission agents) 3.03 rupees (CBR=1:3.03) and date palm grower earned 0.27 rupee (CBR= 1:0.27) on payment of one rupee cost. Among constraints, farm to market infrastructure and high transportation costs were the problems of rank-1 faced by 100 percent of the growers. Market facility to growers, quality seed and irrigation water, lack of date processing unit and cold storage were rank-2, rank-3 and rank-4 problems, respectively. The quality pesticides and high fertilizer and FYM price and timely availability were the problems at rank-5, while training of date palm growers for production and post-harvest handling and non-existence of soil testing facilities were the problems of low ranking.

    Background. Several point mutations in the mitochondrial DNA cause maternally inherited metabolic disorders. The most common type of mutation A3243G in the gene of transfer RNA leucine (tRNALeu(UUR)) is thought to be responsible for the prevalence of type 2 diabetes mellitus. This study was designed to analyze the tRNALeu(UUR) gene of mtDNA of the diabetic individuals with familial history of diabetes to identify the point mutations A3243G. Material and methods. Saliva samples were preferred as a source of DNA to minimize the risk of infection. DNA was successfully extracted from their saliva. Samples of high-quality DNA was amplified with PCR and sequenced in Macrogen Inc. Korea. Results. The m.3243A>G mutation in mitochondrial tRNALeu(UUR) gene was not observed. Conclusion. The result shows that the m.3243A>G mutation in mitochondrial tRNALeu(UUR) gene is not frequent cause of type 2 and some other factors may be possible i.e. genetic, behavioral or environmental. It is recommended that the sample size for diabetic individuals need to be increased for a future study and screened for the mitochondrial as well as other mutations of nuclear origin

    To ensure universal health care, the World Health Organization recognized the significance of complementary and alternative medicines (CAM) and recommended the use of natural herbs and plants bearing therapeutic potential and fewer adverse effects. Therefore, Artemisia annua herb was evaluated for its antibacterial potential and therapeutic efficacy against Staphylococcus aureus, Streptococcus and Escherichia coli both in vitro and in vivo. Artemisinin was extracted from Artemisia annua by chemical treatment. Subsequently, the culture sensitivity tests were performed on MHA by disk diffusion method to determine the antibacterial potential of the Artemisinin extracts against the test bacteria (in vitro phase). The results of this in vitro trial revealed that the test bacteria Staphylococcus aureus and Streptococcus were significantly sensitive to Artemisinin extracts and showed a diameter of 27.7 and 22.3 mm of the bacteriostatic zone, respectively, while the Escherichia coli was moderately sensitive to the Artemisinin extracts with the bacteriostatic zone of 12.9mm. During the 2nd phase of the study (in vivo trial), 20 rabbits were maintained which were infected with S. aureus and were successfully treated with varying concentrations of the Artemisinin extracts @ 1 mg/ml, 2 mg/ml and 5 mg/ml in DMSO and were recovered. Similarly, rabbits infected with Streptococcus were also successfully treated and recovered. Thereafter, rabbits infected with E. coli were treated with Artemisinin, and out of 15 rabbits in three test groups, 03 rabbits died while the others were recovered. Hence, as per findings of this study, Artemisinin extracts were recommended against Staphylococcus aureus and Streptococcus infections
