Abstract
Purpose
Unleavened flat bread (chapatis and rotis) is staple food of the Pakistani population. Almost 90 per cent of wheat produced in the country is used for chapatis and roti preparation. Present study was carried out to prepare composite flour, assess suitable level of composition. The main aim was to increase the mineral content of the diet, as they are deficient in the diet of the Pakistani people as for other developing countries.
Design/methodology/approach
Composite flours were prepared by replacing wheat flour with 8, 16, 24, 32 and 40 per cent soy flour. Composite flour and chapatis were analysed for mineral and phytate contents. Sensory evaluation (color, flavor, taste, texture, folding ability and chewing ability) of chapatis was also carried out to assess acceptance of suitable level by the consumers.
Findings
The statistical analysis of data obtained showed significant increase in minerals (Fe, Zn, Cu, Mn, Ca and Mg) and phytic acid content of flour. Significant decrease in phytate was found during the baking of chapatis. Chapatis were found acceptable by the panel of judges up to 24 per cent supplementation of soy flour. To combat mineral deficiency in developing countries composite flour technology can use as replacement of mineral salts fortification. As in case of composite flour natural source of nutrient are used.
Practical implications
Soy supplementation of wheat flour can be successfully done through flourmills and small‐scale grinders as it causes no problem in milling operations.
Originality/value
The research carried out is one of outstanding type as no such research was done earlier. Phytate besides minerals was also given due consideration in same study which is one of chelating agent found in plant source of minerals.

Abstract
Pakistan's present war against extremists has many folds and sheds. The country's initial participation in the Afghan War in 1979 later gave birth to different extremist trends in the country. State patronage of the extremist Wahabi Islamists during the Afghan jihad opened another conflict in Pakistan, and things became more complicated. The combination of external and internal factors gave birth to the worst kind of conflict, which now has not only become dangerous for the country's own existence but also a major threat for global peace. The Afghan jihad initially started as a war against Soviet occupation and later became the hub of global jihad-war against infidels.
This chapter analyzes how external factors promoted internal contradictions in Pakistan due to which the country became not only an exporter of jihadis for the world but also the worst kind of sectarian conflicts, including. Shia–Sunni, Deobandi–Wahabi clashes, entered into in the past two decades. Such a strong link exists with Pakistan's official support to global jihad. Draft sectarian groups now head to head with their opponents have killed thousands of members of rival sectors, have strong support from external sympathizers, and have spread in the country. The well planned terrorist activities of these groups reflect the fact that support to these groups in the past is now leading to a severe crisis in Pakistan. The nexuses of these indigenous extremists like Lashkar-e-Jhangvi, Lashkar-e-Taiba, Tehrik-e-Taliban Pakistan, and Hizb-ul-Mujahideen with external terrorist organizations like Al-Qaeda, the Taliban, and Islamic Movement of Uzbekistan of Tahir Yuldasher Chechen Guerilla War has led to several bloody clashes in the country and outside.

Abstract
Purpose
The purpose of this study is to focus on Pakistan’s food manufacturing enterprises and explore the knowledge and implications of green innovation, green intellectual capital (GIC) and green human resource management (GHRM) in achieving environmental performance and competitive advantage.
Design/methodology/approach
Using a quantitative approach, this research adopted a cross-sectional survey design to facilitate an objective and precise evaluation of the proposed relationships. The demographic comprised managers and supervisors from food manufacturing enterprises in Lahore, Pakistan. Through purposive sampling, 281 respondents were selected, ensuring representation from food enterprises.
Findings
This study explores that GIC is vital for implementing sustainable technologies in Pakistan’s food sectors. GIC and human resource management are identified as accelerators for green innovation, potentially providing an enhanced environmental performance and competitive edge.
Practical implications
By recognizing the potential of green practices as strategic resources, managers in the Pakistani food sector invest in fostering intangible resources and GIC. This approach leads to sustainable market dominance and efficient operations through continuous green innovation and effective stakeholder communication.
Originality/value
This research offers a consolidated view of the function of GIC in encouraging green innovations in Pakistan’s food enterprises, emphasizing the importance of GHRM procedures and sustainable business methods. This study also provides insights into the strategic management of green projects from a managerial perspective, emphasizing the need for alignment with company strategy and stakeholder communication.

Present work deals with the partial substitution of cement by waste demolished concrete powder (WDP) for reducing the carbon footprints of concrete.
Abstract
Purpose
Present work deals with the partial substitution of cement by waste demolished concrete powder (WDP) for reducing the carbon footprints of concrete.
Design/methodology/approach
Control specimens and the specimens with 20% WDP as fractional substitute of cement were prepared. The waste powder was thermally activated at 825 °C prior to its use in the mix. The prepared specimens were evaluated in terms of density, workability, mechanical strength, Ultrasonic pulse velocity (UPV) and rebound hammer (RH).
Findings
The results showed that with the substitution, the workability of the mix increased, while the density decreased. A decrement within a 20% limit was found in compressive strength. The UPV and RH results were closely linked to the other results as mentioned above.
Research limitations/implications
The study deals with only M15 concrete and the substitution level of only 20% as a baseline.
Practical implications
The concrete containing 20% WDP is lightweight and more workable. Moreover, its strength at 28 days is 14 MPa, only 1 MPa lesser than the characteristic strength.
Social implications
The WDP can be recycled and the dumping in landfills can be reduced. This is an important effort towards the decarbonation of concrete.
Originality/value
Previous literature indicates that the WDP has been frequently used as a partial replacement of aggregates. However, some traces of secondary hydration were also reported. This work considers the effect of partial substitution of cement by the WDP.
