    This study proposed control system that has been presented to control the electron lens resistance in order to obtain a stabilized electron lens power. This study will layout the fundamental challenges, hypothetical plan arrangements and development condition for the Integrable Optics Test Accelerator (IOTA) in progress at Fermilab. Thus, an effective automatic gain  control (AGC) unit has been introduced which prevents fluctuations in the internal resistance of the electronic lens caused by environmental influences to affect the system's current and power values ​​and keep them in stable amounts. Utilizing this unit has obtained level balanced out system un impacted with electronic lens surrounding natural varieties

    This research aimed to investigate the antibacterial activity of Camphor extract ,against biofilm formation of clinical isolates Staphylococcus aureus and Staphylococcus lentus .by detecting the presence and absence of virulence genes that responsible for the biofilm formation after treatment  with Camphor  extract. .thirty isolates were diagnosed initially as Staphylococci then selected five isolates depending on resistance to different type of antibiotics as virulence .After that the isolates test by VITEK-2compact system (ID and AST) to confirm the species of Staphylococci .The diagnostic result showed that three isolates belong to Staphylococcus aureus and two to Staphylococcus lentus. Investigation of the ability of camphor oil to inhibit the growth of bacteria using diffusion method in Muller Hinton agar ,the results showed the effect of camphor oil to prevent biofilm formation  on both bacterial species with concentration (0.1 g/ml )

    This study was carried out to determine bacterial contamination of imported and local corn kernel (used as animal feed) in Iraq, which causes diseases and great economic losses. A total of 163 samples were collected (100 samples of the imported corn kernel from border points and 63 samples of the local corn kernel from the provinces) and cultured then Isolates were identified according to morphological Characteristics, biochemical tests and Agglutination test. The results indicated a total Gram-negative bacteria in 94 samples of the total samples (163) at (58%), includes: 57 Isolates from the imported corn kernel at (57%), which includes :Salmonella spp. in 14 samples at (14%), Escherichia coli in 21 samples at (21%), Klebsiella spp. in 13 samples at (13%), Proteus spp. in 9 samples at (9%) but absence of Serratia spp. and Enterobacter spp. . Addition to 37 Isolates from the local corn kernel at (60%),which includes: Salmonella spp. in 10 samples at (16%), Escherichia coli in 15 samples at (24%), Proteus spp. in 6 samples at (10%), Serratia spp. in 3 samples at (5%), Enterobacter spp. in 3 samples at (5%) but absence of Klebsiella spp. This study concluded that must be evaluated the microbial quality of imported and local corn kernel (used as animal feed) by manufacturers and health authorities to ensure safety and quality of corn to prevent diseases and great economic losses

    The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

    Get PDF
    INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
