It serves as a crucial resource for the Metaverse's future growth and development by guiding developers, stakeholders, and policymakers as they navigate the Metaverse's seemingly limitless potential

Tool Path Definition for Numerical Simulation of Single Point Incremental Forming

AbstractIncremental sheet forming is a promising process for sheet metal prototyping and for bio-medical implants. The entire process cycle is computer integrated and part is manufactured on computer numerical control (CNC) milling machine. This process uses a spherical ended tool to press the sheet into required shape. The path of the tool is controlled by a part program generated using computer aided manufacturing (CAM) softwares. For the numerical simulation of the process tool has to follow the same path as in experimental work. But numerical simulation softwares normally do not accept the G-code file generated using CAM packages directly. In the present paper a methodology has been proposed to input the tool path trajectories generated using CAM packages in to numerical simulation softwares such as ABAQUS and Ls-Dyna. For certain sample symmetric and asymmetric shapes, this proposed methodology has been implemented in Matlab and Ls-Dyna. The results were found to be satisfactory

Seamless Handover between UMTS and GPRS

UMTS is one step ahead from the 2.5G network GPRS and supports faster data rates with wide coverage area. GPRS and UMTS are already deployed in many countries but seamless handover between GPRS and UMTS still remains as a stumbling block for the service providers to fulfill the continuously increasing customer demand for internet and data access in the IP-based wireless network and to maintain incessant connection for the itinerant service consumers. In this paper we propose a method that mongrelizes 3GPP IMS and MIPv4 to resolve the seamless inter-system handover between UMTS and GPRS with a result of no packet loss and minimum latency so that the itinerant service consumers can get services without any interruption

The Impact of Corona Virus (Covid-19) on E-Business in Pakistan.

This study documents the impact of Covid-19 on the E-Business in Pakistan.COVID-19 has a significant influence on public health and induces hasty changes in way of life, social distancing and home alienation, with social and economic implications. This indicates the socioeconomic expansion in the country has deteriorated. It's now messed up all sorts of industry on a global scale including the e-commerce sector. Big retailers had their stores turned off temporarily. In addition, due to declining footfalls, medium-sized and small- sized retailers are battling the situation. For fact, online companies are not off the list as well. Pakistan is also heavily impacted by them. Several e-commerce firms depend on China for most of their goods. In China, lockdown restrictions drastically decreased the production of goods, Thus it is expected to have a big impact on the Pakistan online sector, in particular Chinese goods. Primary research through a sample survey analysis is executed to boost outcomes.The result shows that because China is the biggest producer and the largest number of industries are locked. That’s why all the shipping processes which have hampered domestic economic growth are hindered by the influence of corona viruses

Growing Fashion Consciousness; A Threat to Environment

The Study stands on an assumption that growing fashion consciousness leads towards a general change oriented behavior and so escort towards an intense consumption pattern. To fulfill that huge demand of all kinds, massive industrialization takes place, which is evidently a threat to the environment. Study ascertains the fashion consciousness of only the most neglected segment of the market to establish that people are getting fashion conscious to a threatening level. This study identifies the fashion information sources, shopping preferences and in particular, measures the fashion consciousness of the underappreciated segment as mature female consumers in Pakistan. A comprehensive questionnaire is exposed to the females aging 45 to onwards who were explained with every question in order to ensure the validity of the instrument. It is found that mature women are fashion conscious but not as much as they share information of fashion. Mature women are more concerned about comfort than style and more concerned about style than brand name, which is a clear evidence of lack of advertisement and focus of businesses on this wealthy and independent segment. Even then, they are fashion conscious and acquire fashion information through catalogues, store display, fashion shows, asking family members, and social gatherings. This amplifying fashion consciousness leads to a change oriented behavior in general. People seek change in everything around (even before it expiries) which will obviously generate innovative demands and in result, industrialization will be at its peak; an obvious threat to the environment

DNA extraction and quantification from human saliva deposited on fruits with human bite

Background: Among important aspects of forensic science there stand recovery, preservation and analysis of stains originated by body fluid. DNA Isolated from evidence stains help to exclude an innocent suspect or to identify a perpetrator upon PCR-based typing. This study reports extraction and quantification of DNA from human saliva deposited on fruits. The research work was conducted at Department of Forensic Sciences, University of Health Sciences, Lahore and WTO laboratory of University of Veterinary and Animal Sciences, Lahore.Methodology: DNA from saliva deposited on bitten fruits. DNA from 55 samples were extracted by Chelax method, Quantifiler® DNA Quantification Kit was used for quantification of the extracted samples and amplification of DNA was done in 7500 Real-Time PCR systems (Applied Biosystems, Foster City, CA). Total 55 samples including controls (positive and negative controls) were collected from bitten fruits by sterile swabs.Results: All sample swabs with human saliva showed result for quantification. Overall good yield of DNA quantification obtained from all fruits and no sample showed internal inhibition. No sample showed non informative or incomplete quantification which occurs due to LCN (Low copy number) or lesser quantity of DNA extracted from saliva swab.Conclusion: This study has provided with optimized protocol to isolate DNA from saliva found in very minute quantity on organic surfaces like fruits. Adaptation of this method can play a vital role in establishing new trends in human forensics practiced in Pakistan. Moreover, for future work in human forensics, this study can provide important practical basis

Comparative study to access coagulation abnormalities in breast cancer

Background: Coagulation abnormalities such as thrombosis and disseminated intravascular coagulation (DIC) are the major factors that play a major role in breast cancer. In this study, coagulation abnormalities were assessed in breast cancer patients to help the clinician in early detection of DIC and management of patients at different stages of breast cancer.Methods: 75 patients were enrolled in the study, 50 were from case group (breast cancer patients) and 25 were selected as control group subjects used to compare the results. All of these subjects undergone, General Hematological analysis i.e. differential leukocyte count hemoglobin, platelets count and total leukocyte count were performed on each of the samples collected from the subjects and Specific Hematological analysis i.e. Activated Partial Thromboplastin Time (APTT), Fibrinogen Assay, Prothrombin Time (PT), D-Dimer Detection and Fibrin Degradation Products (FDPs).Results: PT was found to be comparable in patients with breast cancer when compared with controls. Difference between control group (II) and subjects with breast cancer (I) was non-significant, fibrinogen level was found to be significantly increased (p < 0.01) in patients with different stages of breast cancer when compared with controls. FDPs were found to be significantly increased (p< 0.01) in patients of breast cancer when compared with control group. These increased levels of FDPs may be due to enhanced fibrinolysis. D-Dimers were also found to be significantly increased (p < 0.01) in patients with breast cancer when compared with controls.Conclusion: Patients with breast cancer were associated with compensated DIC state including normal PT and APTT level but increased fibrinogen and platelets count as compared to the controls. Detection of D-Dimers offers a differential analysis over other laboratory tests for DIC

Prevalence of HCV in β-thalassemia major patients visiting tertiary care hospitals in Lahore – Pakistan

Post-transfusion hepatitis (PTH) is majorly caused by hepatitis C virus (HCV). So, recipients of blood/blood products, post-transfusion hepatitis (PTH), renal dialysis patients and intravenous drug users all represent high-risk groups for infection. The aim of the present research was to determine the prevalence of HCV antibody in β-thalassemia major patients visiting different tertiary care hospital in Lahore, Pakistan. HCV seroprevalence and risk factors were studied in 200 β-thalassemia major patients (24 females, 176 males) with different age groups by second generation ELISA during January 2013 to May 2013. Confirmed β-thalassemia major patients from three different tertiary care hospitals were selected with special reference to age, age at the time of diagnosis, frequency of transfusion and present clinical status. Among 200 patients, 82 (41%) were found reactive for HCV antibody with age range of 2 to 18 years with mean age of 8.5 years. This study showed that hemodialysis patients and β-thalassemia sufferers were at higher risk of having HCV infection; the prevalence being 41%

Prevalence of syphilis in Pakistani blood donors

Abstract Background: Blood transfusion is one among the common sources for transmission of the infectious diseases. In Pakistan, a country of population about 1.8 billions, blood required for transfusion is approximately 1.5 million bags per year. So, evaluation of the prevalence of syphilis among the blood donors by a retrospective study is important and critical to give a vivid picture of current situation for both the donors involved and medical practitioners.  Method: A questioner was administered and consent was taken before obtaining the blood sample for the syphilis serology from all the blood donors. ARCHITECT syphilis Treponema Pallidum (TP) assay was performed to detect the syphilis.Results: There were 449 (3.1%) confirmed cases found to be syphilis positive out of total 14,352 tested individuals. We found that male population is at far higher risk than female population. Out of 179 females, only 3 (1.6%) were found to be syphilis positive and out of 14173 males, 446 (3.1%) were having syphilis infection.Conclusions: We report high prevalence of syphilis in blood donors which was unexpected as in accordance with the previous studies. This calls for mandatory syphilis screening test of donor before transfusion of blood.  As this high prevalence poses a great risk to public health, we strongly suggest that there should me be more public awareness campaign to fight against this infectious disease

Asymmetric impact of renewable and non-renewable energy on economic growth in Pakistan: New evidence from a nonlinear analysis

This paper explores the asymmetric relationship between renewable energy consumption, non-renewable energy, and terrorism on economic growth of Pakistan. We applied a novel econometric cointegration method known as a nonlinear autoregressive distributed lag modeling (NARDL). Our empirical findings indicate that positive and negative changes have a significant long-run asymmetric relationship between renewable energy, and terrorism on economic growth. We also found a negative and significant effect of non-renewable energy consumption on economic growth. To keep our environment clean and free of emissions, the study specifies policies that rely on renewable energy sources to boost economic growth. However, reduces terrorism has a positive impact on economic growth in the long-run and shows as an influential tool to combat terrorism in Pakistan. These novel results will help policy-makers and government officials to understand better the role of renewable energy and economic growth in Pakistan's development
