Research Review of the Books written by the Scholars of District Haripur in Islamic Studies
No full textIn this article, twelve scholars of District Haripur have been discussed for their significant contribution in Islamic sciences and various religious issues. The fact remains that District Haripur has remained the center for Islamic education wherein almost every school of thought has existed. In this article, those scholars are provided expression who despite been a part of some particular school of thought, have always encouraged intra-faith harmony. For example, "Al Ribat li Rad Hiyla al Isqat" by Maulana Mohammad Azam contains plenty of updated information on this issue. Similarly, another book called as "Mu'in-ul-'Aqaid” by Maulana Mohammad Hassan, provides grounds for rejecting the hypocrisy of society in a befitting manner. Before writing this article, a session was held with those scholars who are still alive whereas details of those dead were collected from their family members

A Novel Multi-Layer Framework for Dynamic Operation of Prosumers in Peer-to-Peer (P2P) Energy Markets
No full textResearch in transactive energy systems, in recent years, has been primarily focused on
the financial aspects of peer-to-peer (P2P) energy trade with little attention paid to the
operational and practical aspects of how this energy trade should occur in a system. Practical prosumer behavior in such systems should be subject to their own internal status and
the external conditions of the electrical network. Moreover, for such practical realization of
a prosumer to be feasible, they should be primed to operate through system disturbances
and parameter uncertainties.
In this thesis, a novel mathematical model is presented to enable prosumers to partake
in P2P energy trades with full operational freedom over their own consumption, energy
storage system (ESS) operation and their distributed power generation capability. The
proposed model integrates a physical system (physical layer) with prosumer operations
(virtual layer) to evolve a multi-layer framework which allows physical network constraints
to be implemented with relative ease. The formulation is implemented on a 33-Bus test
system considering various system objectives and the results demonstrably prove the significance and applicability of the proposed framework in P2P energy markets.
The multi-layer framework is then further extended to enable the prosumer to respond
to uncertainties in the local grid or its distributed energy resources, through an MPC based
approach. The considered uncertainties are further split into categories termed as ’known
uncertainty’ and ’unknown uncertainty’; with the former referring to forecasting errors and
the latter referring to unexpected system disturbances. Several cases are developed considering combinations of system parameters to be uncertain and by introducing disturbances
to observe prosumer responses. The simulation results prominently show the prosumers
responding to unexpected disturbances by adjusting their behavior and P2P energy trade
while maintaining their optimal objectives. Such results demonstrate the viability of this
MPC approach for the realization of a practical prosumer

PEMIKIRAN THABATHABA’I TERHADAP MATAN HADIS-HADIS MUT’AH DALAM AL-MIZAN FI TAFSIR AL-QUR’AN
No full textPenyajian tentang matan hadis-hadis mut‟ah yang terkodifiksi dalam Tafsir al-Mizan fi Tafsir al-Qur‟an. Merupakan karya terbasar Thabathaba’iyang merupakan mengusai berbagai multidisiplin ilmu, termasuk Mufasir dan sekaligus mengusai hadis serta cabang ilmu lainnya dengan menggunaka teori “Fusion of Horizons” Hans-Georg Gadamer sebagai penguat dan karya ilmiah penulisan tesis. Thabathaba’i tidak terikat oleh suatu penafsiran tertentu, Thabathaba’i sangat kritis dan jenius dalam menyikapi suatu hal, termasuk kritis dan idealis dalam menyikapi matan hadis-hadis mut‟ah. Terbukti bahwa Thabathaba’i tidak literal dalam memahami konteks historis sosial munculnya teks matan hadis-hadis mut‟ah dan kontekstual terhadap konteks sosial yang mengitari Thabathaba’isehingga menemukan signifikansi terhadap makna teks historis dan makna konteks atas pembacaan Thabathaba’i.
Perhatian Thabathaba’i terhadap matan hadis-hadis mut‟ah tidak lepas dari argumentasi dan historisitas praktek mut‟ah yang terjadi masa Nabi Muhammad. Mut‟ah pada masa Nabi Muhammad sudah dikenal oleh sahabat dan banyak sahabat yang mempraktekan atas anjuran yang diberikan oleh Nabi Muhammad. Kemudian pemusatan perhatian Thabathaba’i terhadap matan hadis-hadis mut‟ah, yang dibentuk oleh suatu argumen bahwa sandaran larangan mut‟ah adalah Umar, bukan dari Nabi Muhammad. Begitu juga pada faktanya mut‟ah adalah di kontekskan li qayami al-dhararati untuk kemaslahatan dan mensucikan umat dari perbuatan zina. Kemudian perhatian Thabathaba’iterhadap matan hadis-hadis mut‟ah dalam memperbolehkan mut‟ah tidak lepas dari konteks Ayat al-Mu‟minun (24). Ayat tersebut perspektif Thabathaba’iadalah ayat tentang kebolehan mut‟ah. Thabathaba’i menyikapi ayat tersebut adalah mutlak untuk konteks mut‟ah dan kebolehannya. Karena pembacaan Thabathaba’i tidak memperlakukan nasyakh mansukh, baik dari sisi teks al-Qur‟an dan juga matan hadis-hadis mut‟ah.
Thabathaba’i dalam memahami konteks matan hadis-hadis mut‟ah tidak lepas dari dua horizon, yaitu horizon fakta sejarah tentang konteks mut‟ah yang terjadi di masa Nabi Muhammad dan horizon terhadap pembacaan Thabathaba’i pada konteks sosial alam yang menitari Thabathaba’i. Karena menurut pembacaan horizon Thaba>thaba>’i>, bahwa konteks mut‟ah pada faktanya di latar belakangi oleh kebutuahan yang sanagt mendesak, seperti kondisi keberadaan di medan perang dan psiskis sahabat sanagt butuh pada perempuan. Kemudian konteks tersebut oleh Thabathaba’i dikontekskan atas pembacaan ulang matan hadis-hadis mut‟ah terhadap konteks makna idealnya. Karena Thabathaba’i mengamati perkembangan zaman dan pertumbuhan perempuan yang sangat menggoda. Kemudian oleh Thabathaba’i konteks mut‟ah di masa Nabi Muhammad di kontekskan oleh Thabathaba’i atas kebolehan mut‟ah, karena berlandaskan horizon tersebut
Mitigating heavy metal pollution in agriculture: A multi-omics and nanotechnology approach to safeguard global wheat production
No full textThe escalating issue of heavy metal (HM) contamination in agricultural soils presents an urgent challenge to the sustainability of wheat (Triticum aestivum L.) production. This review underscores the critical need for innovative approaches to ensure food security while mitigating environmental degradation. The integration of nano and quantum technologies with multi-omics frameworks emerges as a groundbreaking solution to this pressing issue. HMs like Cd, As, and Pb severely impair plant physiology, leading to diminished yields and compromised grain quality. Nanoparticles such as ZnO, TiO₂, and MnO₂, along with quantum dots, have shown substantial promise in bolstering wheat's natural defense systems, enhancing both enzymatic and non-enzymatic antioxidant pathways, and reducing metal uptake through targeted detoxification mechanisms. By leveraging advanced omics technologies—transcriptomics, ionomics, proteomics, and metabolomics—researchers can unravel key molecular pathways and biomarkers, offering precision-guided interventions for metal stress management. Furthermore, future innovations like genome-editing technologies such as clustered regularly interspaced short palindromic repeats (CRISPR) and transgenic techniques hold the potential to create wheat varieties inherently more resilient to environmental contaminants. The review highlights the necessity of long-term field trials and the exploration of under-researched metals and nanoparticles to bring these promising laboratory findings to real-world application. These combined strategies not only contribute to sustainable agriculture but also provide a viable path toward reducing the ecological footprint of HM contamination, thereby safeguarding global food security.We are very thankful to the Quaid-i-Azam University administration for supporting our work.This research was funded by Quaid-i-Azam University, Islamabad, Pakistan, supporting the investigation of advanced strategies to mitigate heavy metal stress in agricultural systems
Piezoresistive behavior of MWCNT/PA12 honeycomb composites processed via selective laser sintering
No full textThis study examines the piezoresistive and mechanical behaviors of multiwalled carbon nanotube (MWCNT)/polyamide (PA12) lattice composites processed via selective laser sintering (SLS). Firstly, neat PA12 powder was ballmilled with either 0.3, 0.5, or 1.0 wt% MWCNT loading to obtain nanoengineered powder feedstocks. The feedstocks were used to realize electrically conductive MWCNT/PA12 bulk and honeycomb lattice structures via SLS. The piezoresistive and mechanical characteristics of bulk samples were assessed under tensile, compressive, and flexure loadings while those of honeycombs were investigated under in-plane and out-of-plane compression. The morphological and thermal characterizations were carried out to gain insight into the processing-structure-property relations. The microstructural observations, including in situ μ-CT imaging, revealed that the porosity of the sintered parts significantly increased (≈150%) with increasing MWCNT loading, resulting in reduced elastic stiffness and strength of the sintered composites, despite their slightly higher crystallinity (+6% for 0.5 wt% MWCNT loading). The bulk nanocomposites exhibited excellent piezoresistive characteristics, showing a maximum gauge factor of 31 (in compression), which is significantly higher than the sensitivity factors of extant piezoresistive self-sensing composites. The honeycomb structures showed a maximum specific energy absorption of 3 and 24 J g−1 at 40% relative density under in-plane and out-of-plane compression loading, respectively. It was also demonstrated, that the MWCNT/PA12 honeycombs possess excellent strain sensing characteristics due to their pronounced piezoresistivity, reporting gauge factors up to 25 and 17 for in-plane and out-of-plane loading, respectively
Mechanical and piezoresistive behavior of selectively laser sintered MWCNT/UHMWPE nanocomposites
No full textHerein, we present the mechanical and piezoresistive behavior of MWCNT/UHMWPE nanocomposites processed via selective laser sintering (SLS) under tensile, flexural and cyclic loadings. We show that the uniform dispersion of MWCNTs in UHMWPE enhances crystallinity (+10% for 0.5 wt.% MWCNT) and decreases porosity (as evidenced by μCT images), evincing the lowest porosity (∼ 1%) and the highest tensile strength of 20.3 MPa which is ∼45% higher than the maximum tensile strength of extant SLS processed UHMWPE and UHMWPE-based composites. The nanocomposite also exhibits superior piezoresistive characteristics, showing a sensitivity (in tension) of 0.6 and 2.6 in the elastic and inelastic regime, respectively. Furthermore, 2D-hexagonal nanocomposite lattices with a relative density of 50% reveal a linear piezoresistive response with a gauge factor of 1 and show consistent and stable strain sensing capability over 100 cycles. The results demonstrate the potential of MWCNT/UHMWPE nanocomposites for the development of smart biomedical devices
Rewriting history : postmodern and postcolonial negotiations in the fiction of J.G. Farrell, Timothy Mo, Kazuo Ishiguro and Salman Rushdie
No full textThis thesis is a study of the rewriting of history in the work of four novelists: J. G. Farrell, Timothy Mo, Kazuo Ishiguro and Salman Rushdie. I argue that their work occupies a particular position that is both within contemporary British fiction, yet at one remove from it.
Their work is situated within the context of critiques of history that are the source of a conflict between postmodernism and postcolonialism. I suggest that each writer engages with postmodemist aesthetics often in an attempt to produce critical histones that bear witness to the voices of those hitherto silenced in conventional historiography. However, these novelists remain anxious as to the potential consequences of mobilising postmodernist models of history, particularly as to the problems this creates concerning historical reference. The thesis aims to
identify the range of related attitudes to postmodernist critiques of history at this particular juncture of contemporary fiction in English.
I approach the specific position of the novelists under study through Homi Bhabha's work on the confluence of the postmodern and the postcolonial, focusing in particular on his suggestion that the postmodem refutation of Western epistemology enables a postcolonial space where a new range of histories emerge. Because each writer works between at least two cultures, and primarily within Britain, they negotiate from within received epistemology in an attempt to locate a space at its boundaries where conventional forms of knowledge no longer have efficacy. However, in contrast to Bhabha, these writers struggle to reach this space and remain sceptical as to the usefulness of postmodernism in making available new forms of
historiography. Ultimately, their work enables a critique of current ways of theorising the relationship between the postmodem and the postcolonial in literary studies
