    Abstract Salinity and waterlogging are the widespread problems of many areas of Pakistan. Wheat varieties were tested at salinity, waterlogging and saline-waterlogging treatments for their performance to Na + , K + , stomatal conductance, SPAD (Special Products Analysis Division) chlorophyll, grain dry weight, ear/plant and grain/plant measurements. Na + content in leaves was continuously increased with saline and saline-waterlogged treatments. Also, K + content was increased with salinity treatment but decreased with saline-waterlogged treatment. Stomatal conductance decreased with waterlogging, saline and saline-waterlogged treatments but SPAD readings were not influenced by these treatments. Generally, waterlogging increase the grain dry weight, ear and grain number per plant. However, this was greatly reduced by saline and salinewaterlogged treatments in all varieties

    Person Identification through Harvesting Kinetic Energy

    Energy-based devices made this possible to recognize the need for batteryless wearables. The batteryless wearable notion created an opportunity for continuous and ubiquitous human identification. Traditionally, securing device passwords, PINs, and fingerprints based on the accelerometer to sample the acceleration traces for identification, but the accelerometer's energy consumption has been a critical issue for the existing ubiquitous self-enabled devices. In this paper, a novel method harvesting kinetic energy for identification improves energy efficiency and reduces energy demand to provide the identification. The idea of utilizing harvested power for personal identification is actuated by the phenomena that people walk distinctly and generate different kinetic energy levels leaving their signs with a harvested power signal. The statistical evaluation of experimental results proves that power traces contain sufficient information for person identification. The experimental analysis is conducted on 85 persons walking data for kinetic power signal-based person identification. We select five different classifiers that provide exemplary performance for identifying an individual for their generated power traces, namely NaiveBayes, OneR, and Meta Bagging. The experimental outcomes demonstrate the classifier's accuracy of 90%, 97%, and 98%, respectively. The Dataset used is publicly available for the gait acceleration series

    The study was conducted to determine the prevalence of gastrointestinal nematodes of goats (n=1065) in and around Hyderabad using qualitative and quantitative coprological examinations. Results revealed that 43.10% (459) goats were infected with different species of nematodes including Haemonchus contortus (14.65%), Trichuris ovis (8.17%), Trichostrongylus axei (7.61%), Trichostrongylus colubriformis (6.76%), Oesphagostomum columbianum (5.35%), Ostertagia circumcincta (5.35%), Chabertia ovina (4.79%) and Strongyloides papillosus (4.51%). Infections with mixed species of nematodes were recorded in 6.54% (n=30/459; T. ovis + H. contortus), 5.23% (n=24/459; C. ovina + H. contortus), 5.88% (n=27/459; S. papillosus + C. ovina), and 12.42% (n=57/459; O. circumcincta + T. ovis) goats. Of the total infected (n=459); 51.4, 38.3 and 10.2% goats had light, moderate and heavy infections, respectively. The prevalence, nature and intensity of the helminthiasis in goats warrant an immediate attention to devise strategies for its control to reduce the production losses

    Assessment of Soil Quality of Taluka Thari Mirwah, District Khairpur, Sindh, Pakistan

    Soil salinity is an increasing threat for agriculture. The knowledge of physical and chemical properties of the soil is vital for the assessment of the capacity of soil for better plant productivity and improvement through management practices. We assessed the soil of ten union councils of Taulka Thari Mirwah, district Khairpur. The soil was evaluated for pH, EC, organic matter and salt contents through standardized methods. The overall soil was found to be slightly alkaline (pH 8 ± 0.6 SD), with a varied texture among the sites. The soil EC (10 ± 7.9 SD dS/m) was recorded to be comparatively higher than the surrounding districts. The study did not find any significant variation in various salt contents in the area. The organic contents were lower than the advised extent. However, the management practices were suggested to improve the health of soil for better productivity

    Polyembryony is the most beneficial and distinct character in citrus seeds. This characteristic can be beneficial in citrus improvement programs. Nucellar embryos developed from nucellar wall in citrus seeds along with zygotic embryo are found to have high plants regeneration ability in comparison to zygotic embryos. Under In vitro culture conditions, nucellar embryos were detected and multiplied on MT media with 0.5ml of coconut water along with 50g/L sucrose. These nucellar embryonic tissues were also regenerated on MT media supplemented with 0.5 mg/L BAP and 0.5 mg/L kinetin. Many shoots were regenerated from nucellar embryonic tissue; these shoots were rooted on MT media supplemented with IBA 0.5mg/L and NAA 0.1 mg/L in addition to activated charcoal 0.5gm/L. The resulting plantlets were acclimatized in the green house. After micropropagation, histological studies of nucellar embryonic tissues were carried out under fluorescence microscope to examine their high regeneration ability in comparison with usual plant parts, like seeds, shoots as well as with tissue culture stages including embryogenic and non-embryogenic callus. It was found that nucellar embryos have more regeneration ability as compared to usual plant parts and other tissue culture stages
