    In this article, efficient minimal circular weakly balanced RMDs are constructed for the situations where these designs cannot be constructed through generators. Catalogues of these efficient designs are compiled in periods of three different sizes. In the proposed designs, v/2 ordered pairs of distinct treatments do not appear as their preceded value while the remaining ones appear once, where v is number of treatments to be compared

    Impact of Money Supply and Exchange Rate on Agricultural Prices in Pakistan

    Get PDF
    This study analyzed the impact of the long-run neutrality of money supply and exchange rate on Pakistan's agricultural prices using data from 1975 to 2019. Engle and Granger and Johansen and Jusileius techniques were used to analyze the data. The results showed that the exchange rate's neutrality does not hold in the long-run. Simultaneously, the money supply coefficient was found to be insignificant in the long-run, emphasizing money's neutrality. The study concluded that monetary authorities can control the exchange rate by designing and implementing appropriate policies to overcome the overshoot problem of agricultural prices in Pakistan

    A PRELIMINARY INVESTIGATION OF GEMSTONES, MINES,MINERS AND PROBLEMS IN GILGIT-BALTISTAN, PAKISTAN

    Gilgit-Baltistan possesses a complex history of crustal evolution and rich diversity of geological environments, and is favorable for various types of mineralization and production of gemstone all over GB. Two batholiths; Kohistan Batholith and Karakorum Batholith which are hosting gemstones mineralization. This investigation reveals that thirty-two precious and semi-precious stones are mined, 95% of the total gemstones produced in Pakistan come from GB. These varieties of gemstones come from 2150 mines which are in working conditions scattered all over GB and number of miners involved is 25000. Miners face problems like lighting, ventilation and drilling. They lack the basic safety equipment like helmets, mining shoes, gloves, googles and masks. Due to the fumes of explosives, miners are suffering from different diseases like Silicosis. The main gemstone-producing areas are Hunza valley, Sumayar (Nager Valley), Shengus and Haramosh (District Gilgit), Bulachi and Mir Malik (District Astore), Istak Nalah and Shiger Valley. The common gemstones mined are ruby, pargasite, spinel, corundum, sapphire, calcite, aquamarine, tourmaline, beryl, quartz, topaz, albite, microcline, apatite, fluorite, emerald, marganite, diopside, tanzanite, axinite, felsite, kunzite, emerald and garnet

    In the present study, the toxicity potential of ammonium chloride and urea-based deep eutectic solvent (DES) was studied. A homogeneous DES solution was obtained by heating at 60°C for 20 minutes. Fourier Transform Infrared Spectroscopy (FTIR) analysis was used to verify the synthesis. The toxicity profiling of ammonium-based DES was performed using in vitro cell lines (fibroblast growth factor) and microbes (fungi, Gram positive and gram negative bacteria) and in vivo model organism (fish). DES was found to the had maximum zone of inhibition against tested bacterial (Staphylococcus aureus) and fungal strains (Candida albicans). Ammonium chloride-urea DES had higher LC50 against Cyprinus carpio. DES was found to have a higher percentage of cell viability at higher concentration along with DPPH scavenging activity of 92%. In conclusion, ammonium chloride-urea based DES had been successfully formed and found less harmful at higher concentrations, thus can be used as promising solvents in the future

    A Generalized Class of Circular Designs Strongly Balanced for Neighbor Effects

    Get PDF
    Minimal strongly balanced neighbor designs are useful (i) to minimize the bias due to neighbor effects economically, and (ii) to estimate the direct effect and neighbor effects independently. Such designs can easily be obtained for v odd and are available in literature. In this article, A generalized class of minimal circular designs strongly balanced for neighbor effects in blocks of equal and two different sizes have been constructed in which only v/2 unordered pairs of treatments do not appear as neighbors, where v is the number of treatments

    Some New Constructors of Circular Strongly Generalized Neighbor Designs

    Get PDF
    Minimal strongly balanced neighbor designs are well known designs to balance the neighbor effects at low cost as well as to estimate the direct effects and neighbor effects independently for v odd, where v is number of treatments to be compared. Minimal strongly generalized neighbor designs are used to minimize the bias due to neighbor effects for v even. In this article, constructors are developed to construct two useful classes of minimal circular strongly generalized neighbor designs

    Vulnerability of Environmental Resources in Indus Basin after the Development of Irrigation System

    Get PDF
    The climatic and topographic characteristics of Indus Basin provided an excellent condition for the development of irrigation system. Archaeological remains of Harappa and Mohenjo-Daro indicated that several canals were constructed in this region. The Indus River System (IRS) was developed into a complex network of canals, and 74% of its water was utilized for irrigation after Indus Water Treaty. After 1947, Indus irrigation network was extended, and cropland area was increased from 8.5 to 18.2 MH in Pakistan and 2.02 to 8.5 MH in India. Construction of dams, barrages, and canals to divert the maximum river water for irrigation resulted in drying up the natural pathways of the rivers, except during monsoon season. The aquifer in the irrigated areas became high and created problems of waterlogging and salinity, but due to extensive groundwater extraction, water table near urban centers is lowered now. Water quality was degraded due to addition of fertilizers, pesticides, chemicals, municipal sewage, and industrial effluents. Due to climate change, the glaciers in the upper catchment areas are continuously retreating and the frequency of floods and droughts is increasing. The objective of this chapter is to provide a comprehensive review of irrigation system developments in Indus Basin and its implications on environmental resources
