        Irrigation Management in Spring Planted Sunflower (Helianthus annuus L.) sown with Different Planting Methods

        Muhammad Shahid,Abdul Khaliq,Naveed Ahmad,Khawar Jabran,Mohsin Zafar,Muhammad Rafiq,Mubshar Hussain 한국국제농업개발학회 2012 韓國國際農業開發學會誌 Vol.24 No.1

        This study was conducted to determine the influence of irrigation levels on spring planted sunflower (Helianthus annuus L.) sown with different planting methods. Sunflower was sown either on 60 cm apart single rows on flat seed-bed or on ridges. Three irrigation treatments were I0 (irrigation at early vegetative stage, at bud visible stage, at anthesis and at achene development stage), I1 (irrigation at early vegetative stage, at bud visible stage and at achene development stage) and I2 (irrigation at early vegetative stage, at bud visible stage and at anthesis stage). In I1, irrigation was missing at anthesis and in I2 irrigation was missing at achene development stage. Sunflower yield and yield components showed positive response to ridge sown sunflower with normal four irrigations. Maximum achene yield 3.33 t ha-1 was recorded in ridge sown sunflower with four irrigations. Oil content percentage was highest in case of I0 (42.25%) while the effect of planting methods on oil content was insignificant.

        SELECTION OF A SUITABLE METHOD FOR THE SYNTHESIS OF COPPER NANOPARTICLES

        ASIM UMER,SHAHID NAVEED,NAVEED RAMZAN,MUHAMMAD SHAHID RAFIQUE 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2012 NANO Vol.7 No.5

        Various methods for the synthesis of copper nanoparticles employing chemical, physical and biological techniques considering bottom-up and top-down methods synthesis have been studied. The properties of copper nanoparticles depend largely on their synthesis procedures. The results from various investigations performed by di®erent scientists using these methods have been summarized. The applications, characterization techniques, advantages and disadvantages of each synthesis method are also the point of discussion. A detailed study of the results reveals that chemical reduction methods are most suitable for the synthesis of copper nanoparticles. Chemical reduction of copper salts using ascorbic acid (Vitamin C) is a new and green approach in which ascorbic acid is used both as the reduction and capping agent. This approach is the most e®ective and is also economical. Wide applications have been reported in various ¯elds, including heat transfer, catalyst production, electronics and medicine at a commercial scale. This process is nontoxic, environment-friendly and economical. The applications, characterization techniques, advantages and disadvantages of each synthesis method have been presented.

        A UML-based Approach towards Test Case Generation and Optimization

        Shahid Saleem,Saif U. R. Malik,Bilal Mehboob,Roobaea Alroobaea,Sultan Algarni,Abdullah M. Baqasah,Naveed Ahmad,Muhammad Hasnain 한국인터넷정보학회 2024 KSII Transactions on Internet and Information Syst Vol.18 No.3

        Software testing is an important phase as it ensures the software quality. The software testing process comprises of three steps: generation, execution, and evaluation of test cases. Literature claims the usage of single and multiple 'Unified Modeling Language' (UML) diagrams to generate test cases. Using multiple UML diagrams increases test case coverage. However, the existing approaches show limitations in test case generation from UML diagrams. Therefore, in this research study, we propose an approach to generate the test cases using UML State Chart Diagram (SCD), Activity Diagram (AD), and Sequence Diagram (SD). The proposed approach transforms UML diagrams into intermediate forms: SCD Graph, AD Graph, and SD Graph respectively. Furthermore, by integrating these three graphs, a System Testing Graph (STG) is formed. Finally, test cases are identified from STG by using a traversal algorithm such as Depth First Search (DFS) that is an optimization method. The results show that the proposed approach is better compared to existing approaches in terms of coverage and performance. Moreover, the generated test cases have the ability to detect faults at the unit level, integration, and system level testing.

      • Synthesis, characterization and potential applications of Ag@ZnO nanocomposites with S@g-C<sub>3</sub>N<sub>4</sub>

        Ahmad, Naveed,Javed, Mohsin,Qamar, Muhammad A.,Kiran, Umbreen,Shahid, Sammia,Akbar, Muhammad B.,Sher, Mudassar,Amjad, Adnan Techno-Press 2022 Advances in materials research Vol.11 No.3

        It includes the synthesis of pristine ZnO nanoparticles and a series of Ag-doped zinc oxide nanoparticles was carried out by reflux method by varying the amount of silver (1, 3, 5, 7 and 9% by mol.). The morphology of these nanoparticles was investigated by SEM, XRD and FT-IR techniques. These techniques show that synthesized particles are homogenous spherical nanoparticles having an average particle size of about 50-100 nm along with some agglomeration. The photocatalytic activity of the ZnO nanoparticles and Ag doped ZnO nanoparticles were investigated via photodegradation of methylene blue (MB) as a standard dye. The data from the photocatalytic activity of these nanoparticles show that 7% Ag-doped ZnO nanoparticles exhibit much enhanced photocatalytic activity as compared to pristine ZnO nanoparticles and other percentages of Ag-doped ZnO nanoparticles. Furthermore, 7% Ag-doped ZnO was made composites with sulfur-doped graphitic carbon nitride by physical mixing method and a series of nanocomposites were made (3.5, 7.5, 25, 50, 75% by weight). It was observed that the 25% composites exhibited better photocatalytic performance than pristine S-g-C 3 N 4 and pure 7% Ag-doped ZnO. Tauc's plot also supports the photodegradation results.

        Industrial Internet of Things Based Efficient and Reliable Data Dissemination Solution for Vehicular Ad Hoc Networks

        Latif, Shahid,Mahfooz, Saeed,Ahmad, Naveed,Jan, Bilal,Farman, Haleem,Khan, Murad,Han, Kijun WILEY INTERSCIENCE 2018 WIRELESS COMMUNICATIONS AND MOBILE COMPUTING Vol.2018 No.-

        <P>Industrial Internet of Things (IIoT) is the other name of industrial Internet. It integrates a variety of existing industrial automation technologies with computing, machine learning, and communication technologies. Vehicular ad hoc network, an application of IIoT, is a self-organized network of vehicles which tends to provide improved road safety, diminished traffic congestion, and ultimate comfort to the travellers. In VANETs, vehicles exchange data with each other directly or through roadside units (RSUs). Data dissemination in VANETs experiences numerous challenging issues including broadcast storm, network partitions, intermittent connectivity between vehicles, and limited bandwidth. In literature, various data dissemination schemes are proposed. However, most of these schemes are designed for either urban or highway VANET scenarios and evaluated under sparse or dense traffic conditions. Moreover, these schemes do not effectively overcome the aforementioned issues simultaneously. In this paper, we present a new data dissemination protocol for VANETs, which disseminates the emergency messages in different scenarios under varying traffic conditions. During dense traffic conditions, DDP4V employs the segmentation of transmission region of a vehicle in order to select the most appropriate next forwarding vehicle (NFV). Accordingly, it divides the transmission region of a vehicle in three distinct segments and selects vehicle(s) inside the highest priority segment to forward the message to all neighbour vehicles, whereas it also uses implicit acknowledgements for guaranteed message delivery during sparse traffic Conditions. Simulation results show that DDP4V protocol outperforms the other existing related protocols in terms of coverage, network overhead, collision, and end-to-end delay.</P>

        Partial fetotomy: technique to resolve wry neck dystocia in mare

        Hassan, Mubbashar,Shahid, Sana,Asif, Akhtar Rasool,Naveed, Muhammad Ilyas,Shahzad, Abid Hussain,Khan, Mumtaz Ali The Korean Society of Animal Reproduction and Biot 2020 한국동물생명공학회지 Vol.35 No.4

        Foaling is a process of giving birth to foal which is prompt and forceful event in equine breeding. Dystocia is declared when 2nd stage of parturition exceeds from 20 min without fetal movements in mare. Dystocia is very challenging situation for both mare and veterinarian. Survivability of mare and foal, and subsequent fertility of mare depends on efficient management. Therefore, the current report described a rare case of wry neck (torticollis or unilateral bent neck) resulted in dystocia, that was efficiently resolved by partial fetotomy and repulsion technique in mare under field conditions. Intensive post operative care was performed to avoid infection and to achieve fertility subsequently.

        Biosorption of copper(II) on prunus amygdalus shell: Characterization, biosorbent size analysis, kinetic, equilibrium and mechanistic studies

        Mohsin Kazmi,Nadeem Feroze,Shahid Naveed,Syed Hassan Javed 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.10

        Deletion of Cu(II) from synthetic solution was investigated using ground Prunus Amygdalus shell (GPAS). FTIR revealed the probable functional groups for the binding of Cu(II). XRD revealed amorphous nature of the GPAS. SEM analysis furnished microscopic details of GPAS. GPAS size analysis was done using seven ASTM screens and three mean diameters, namely mass mean, volume mean and volume surface mean diameters. Kinetic study consisted of pseudo-first and pseudo-second order kinetics. Langmuir and Freundlich isotherms were used to elucidate the isotherm study of uptake of Cu(II) onto GPAS. Trend of Scatchard was used to verify the applicability of the Freundlich model, while D-R model helped to determine the nature of biosorption. A detailed analysis for rate controlling step was made. Various mean diameters were used to estimate the diffusion coefficient for the biosorption of Cu(II) onto GPAS.

        Effect of increasing dietary metabolizable protein on nitrogen efficiency in Holstein dairy cows

        Muhammad Imran,Talat Naseer Pasha,Muhammad Qamer Shahid,Imran Babar,Muhammad Naveed ul Haque 아세아·태평양축산학회 2017 Animal Bioscience Vol.30 No.5

        Objective: The objective of the study was to determine the effects of increasing levels of metabolizable protein (MP) on lactation performance and nitrogen (N) efficiencies in lactating dairy cows. Methods: Nine multiparous cows in mid lactation [113±25 days in milk] received three treatments in a 3×3 Latin square design with a period length of 21 days. The treatments were three diets, designed to provide similar energy and increasing supply of MP (g/d) (2,371 [low], 2,561 [medium], and 2,711 [high] with corresponding crude protein levels [%]) 15.2, 18.4, and 20.9, respectively. Results: Increasing MP supplies did not modify dry matter intake, however, it increased milk protein, fat, and lactose yield linearly. Similarly, fat corrected milk increased linearly (9.3%) due to an increase in both milk yield (5.2%) and milk fat content (7.8%). No effects were observed on milk protein and lactose contents across the treatments. Milk nitrogen efficiency (MNE) decreased from 0.26 to 0.20; whereas, the metabolic efficiency of MP decreased from 0.70 to 0.60 in low to high MP supplies, respectively. The concentration of blood urea nitrogen (BUN) increased linearly in response to increasing MP supplies. Conclusion: Increasing MP supplies resulted in increased milk protein yield; however, a higher BUN and low MNE indicated an efficient utilization of dietary protein at low MP supplies.

        Economic Burden of Periprosthetic Joint Infection Following Primary Total Knee Replacement in a Developing Country

        Faizan Iqbal,Bilal Shafiq,Syed Shahid Noor,Zulfiqar Ali,Nouman Memon,Naveed Memon 대한정형외과학회 2020 Clinics in Orthopedic Surgery Vol.12 No.4

        Background: Periprosthetic joint infection is one of the devastating complications after primary total knee arthroplasty, which increases the financial burden on patients and affects their quality of life as well. The financial burden of periprosthetic joint infection after joint replacement in developed countries is well known. There is a need to evaluate the economic burden in developing countries such as Pakistan. Methods: This is a single-center, retrospective, case-control study conducted at the Department of Orthopedic Surgery, Liaquat National Hospital Karachi. Cases of primary total knee arthroplasty performed during this study were divided into 2 groups: uneventful primary total knee arthroplasty and periprosthetic joint infection treated with 2-stage revision. To calculate the final cost, we divided the total hospital cost into the hospital stay cost and operating room cost. Results: During study period, 32 patients were diagnosed with periprosthetic joint infection. The total cost of revision surgery for periprosthetic joint infection considering 2 hospitalizations was 1,780,222 ± 313,686 Pakistani rupee (PKR). The total cost of uneventful arthroplasty was 390,172 ± 51,460 PKR. We observed significant difference with respect to economic details between the 2 groups. Conclusions: Management of periprosthetic joint infection was 4.5 times more expensive than uneventful primary total knee arthroplasty. Measures should be undertaken to reduce the prevalence of periprosthetic joint infection, thereby reducing patients’ economic burden.
