Muhammad Ishtiaq Ishaq,Nazia Hussain,Waseem Khaliq,Muhammad Waqas 한국유통과학회 2012 Asian Journal of Business Environment (AJBE) Vol.2 No.2

Purpose - Today’s world is rapidly changing due to swift changes in organization’s infrastructures and supply chain is becoming an important factor which affects the organization’s global competitiveness. Research design / data / methodology - Researchers indicated that environment uncertainty is considered an external driving force to establish a unique supply chain. Market competition, reducing the gap of performance and quality between the products are compelling the practitioners and researcher to change the paradigm of managing the business processes effectively and efficiently. Results - In old times, supply chain of any organization was measured on the basis of inventory turns, defect rats, lead times, stock buffering and service level. But, Lee H.L. in 2004, published an article in Harvard Business Review who proposed three A (Adaptable, Agile and Aligned) termed as “Triple-A” of successful supply chain. Conclusions - He claimed that organizations can compete through the creation of Triple-A supply chain. Hence, the basic aim of this review paper is to develop basic insights regarding what is Triple-A of supply chain, its importance and functioning in today’s competitive world.

Elaeagnus umbellata is a plant that grows in the hilly areas of Pakistan. Free radical scavenging activities and anti-lipid peroxidative properties of hot water, methanol, n-hexane, and acetone extracts of E. umbellata berries were evaluated. Extracts showed inhibition against thiobarbituric acid reactive species (TBARS) induced using the pro-oxidants iron (10 μM FeSO4) and sodium nitroprusside (5 μM) in brain and liver homogenates of mice. Extracts also showed metal chelating activities of IC50 (extract concentration that causes 50% scavenging)=40-43 μg/mL and DPPH radical scavenging activities of IC50=45.4- 49 μg/mL. HPLC analysis revealed the presence of gallic, vanillic, coumaric, ferulic, sinapic, and caffeic acids in berries. The fruit of E. umbellata is a potential source of antioxidants with therapeutic importance.

Fakhar Zaman,Muhammad Waqas Ishaq,Aisha Munawar,Umer Younas,Zahid Ali 한국탄소학회 2023 Carbon Letters Vol.33 No.7

Energy storage for sustainable development and progress of power production industries is vitally important. The energy storage devices are under extensive research from last three decades to ensure the hand-on-hand coordination with power supply phenomenon and to reduce the energy loses in lines. The cost-effective materials are still highly demanding as an electrode material for energy storage devices. Biomass-derived carbon materials are best candidates due to their low cost, relatively high abundance, pollution-free nature. Here, we are reporting a facile two-step green approach to convert Himalayan horse chestnuts (HHCNs) into activated carbon materials. In first step, grinding and pyrolysis of the HHCNs were carried out, and then activation was performed using KOH to enhance the pore density and surface area. HHCNs-derived carbon was utilized as an electrode in electrical double-layer capacitors (EDLCs) with 1 M H2SO4 as an electrolyte. The macroporous structure along with hierarchical porous network acts as an efficient source of transportation of charges across the electrode and separator. Cyclic voltammetry test was taken from 10 to 100 mV/s current and within a range of 0–1 V applied potential; approximately rectangular CV shown mirror response towards current and shown typical EDLCs properties. The proximate analysis confirms the presence of heteroatoms like sulfur, oxygen, and nitrogen which act as carbon dopants. The wettability of HHCNs-derived carbon enhanced due to the various types of oxygen functionalities inherited from the lignin skeletal part. The nitrogen content is primarily responsible for the pseudo-capacitive behavior of HHCNs-codoped carbon. HHCNs-derived activated carbon materials has emerged as a promising electrode material for energy storage applications.

Phatak, Sohail Ahmad,Chaudhary, Muhammad Azam Ishaq,Khattak, Muhammad Sajid,Naveed, Anjum International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.3

Ombudsmanship is the framework to provide the speedy administrative justice to poor man which is originated in Sweden in the 19^th Century and the modus operandi with modernized arrangement of public grievance redressal. Pakistan has thirteen different Ombudsman Institutions at both Federal and Provincial level with limited public accessibility. This paper presents a collaboration framework for extending the outreach of Ombudsmanship at proverbial doorstep of complainants. This framework has three main components as collaborative arrangements, Proceedings and Resolution of the complaints that increased the public trust. A pilot project titles Swift Complaint Resolution (SCR) was constructed and executed by Federal Ombudsman Secretariat to materialize the concept of speedy redressal of complaints. The SCR project first affirmed the strength of the components of the framework. The concept of SCR was first presented in the Federal Advisory committee for Administrative Justice, which comprised of highest level of the Parliamentarians, Public Officials, NGOs and Civil Society where presented guidelines to be adopted for the free and speedy redressal of grievances at proverbial doorsteps in tehsils and district headquarters ultimately to the extended to the union councils. In SCR, the complaints were decided within 25 days even though the Law permitted 60 days that is itself a record in any judicial /quasi-judicial forum.

Ahmed Raja Qaiser,Ishaq Mohammad,Shoaib Muhammad 한국외국어대학교 국제지역연구센터 2021 International Area Studies Review Vol.24 No.4

This study investigates the changing political trends in erstwhile Federally Administered Tribal Areas of Pakistan. Analysis of the last three elections (2008, 2013, 2018) shows a substantial change in the region. The tribal structure, local traditions, power arrangement and electoral practices have changed significantly over a decade. The extension of the Political Parties Order to the region and its merger with Khyber Pakhtunkhwa stimulated political activities in the area that increased the political awareness of tribal people. The results of the 2013 and 2018 elections highlight the changes. Electoral activities, women participation and voter turnout increased with every election. Tribal youth joined existing political forums to demand their democratic rights. A significant percentage of the young, educated Pashtuns joined the Pashtun Tahafuz Movement in its demand for improved governance.

Hybrid DC circuit breaker with fault current suppression capability

Mei, Mingwan,Wang, Ping,Che, Yanbo,Ishaq, Muhammad,Xing, Chao The Korean Institute of Power Electronics 2021 JOURNAL OF POWER ELECTRONICS Vol.21 No.10

Due to the rapid development of DC transmission, research on DC side fault protection has also made significant progress. The bipolar short-circuit fault is one of the most severe types of DC side faults. It can cause a current surge, which affects the safe operation of a system. Therefore, this paper proposes a new type of hybrid DC circuit breaker (DCCB) to realize the rapid suppression of bipolar short-circuit current. The new DCCB consists of three parts: a nominal current branch (NCB), an energy absorption branch (EAB), and a freewheeling branch (FB). Different control strategies can be adopted to achieve line protection functions for different types of faults. For transient faults, the absorption and suppression of the fault current are achieved mainly through the EAB and FB. The DCCB ensures that the amplitude of the current delivered by the DC line is maintained in a safe operating area of the transmission line. The EAB is disconnected after a short-term of operation for permanent faults to achieve complete isolation between the converter side and the fault side. The parameter design of the DCCB is carried out to provide a reference for the practical application of this research. Finally, the effectiveness of the proposed DCCB protection strategy is verified by simulations, and the function of the DCCB is further verified by experiments.

Mohammad Zuber,Khalid Mahmood Zia,Muhammad Ashair Iqbal,Zahida Tariq Cheema,Muhammad Ishaq,Tahir Jamil 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.1

The present research work was performed to study the properties of polyurethanes (PU) based on ali-phatic diisocayanate and the effect of chemical structure of chain extenders. Two series of PUs were synthesized via twosteps polymerization technique. The PU samples constituted on hexamethylene diisocayanate (HDI), hydroxy-termi-nated polybutadiene (HTPB) and blends 1, 4 butanediol (BDO)/bisphenol A (BPA) and or 1, 4 butanediol (BDO)/bisphenol S (BPS) were prepared. Structural characterization was done using Fourier transform infrared spectroscopyduring and after the synthesis. The FTIR analysis confirmed the existence of proposed bisphenol A (BPA) and bisphe-nol S (BPS) based PU structures. Differential scanning calorimeter (DSC) analysis gives information about the thermaltransition of all the polymer samples. Because of the difference of polarity between hard and soft segments of PU,microphase separation can occur. The degree of phase separation in the prepared PU was confirmed using scanningelectron microscope (SEM) technique. The SEM techniques present a distinctive chance to directly visualize the mor-phology of the polyurethanes.

MeV carbon ion irradiation-induced changes in the electrical conductivity of silver nanowire networks

Bushra Bari,Shehla Honey,Madhuku Morgan,Ishaq Ahmad,Rauf Khan,Arshad Muhammad,Khalid Alamgir,Shahzad Naseem,Maaza Malik 한국물리학회 2015 Current Applied Physics Vol.15 No.5

MeV carbon ion irradiation-induced changes in the electrical conductivity of Silver nanowire (Ag-NW) networks is demonstrated systematically at different C+ ion fluences ranging from 1 × 1012 to 1 × 1016 ions/cm2 at room temperature. At low C+ ion fluences, the electrical conductivity of Ag-NWs decreases and subsequently increases with increase fluence. Finally, at high C+ ion fluences, conductivity again decreases. The variation in the electrical conductivity of Ag NW network is discussed after analysis using scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The observed increase in electrical conductivity is thought to be due to ion induced coalescence of Ag-NWs at contact position, which causes reduction of wire-wire contact resistance, while the decrease in electrical conductivity may be due to defect production by C+ ions into Ag-NWs. Ion beam technology is therefore a very promising technology that is capable of fabricating highly conductive Ag-NW networks for transparent electrodes. Moreover, a method for thinning, slicing and cutting of Ag-NWs using ion beam technology is also reported.
