The Widal test is a serological method used to diagnose typhoid or enteric fever caused by Salmonella typhi, Salmonella paratyphi A, B, and C. It detects antibodies in patient serum that agglutinate specific antigens prepared from Salmonella species. A positive result indicates a recent or past infection. While it has low specificity and can be difficult to interpret, the Widal test remains useful for diagnosing typhoid fever in developing countries due to its low cost. More specific tests such as Typhidot and PCR are also used but are more expensive. The document provides details on how to perform and interpret the Widal test as well as alternative diagnostic methods for typhoid fever.
Pneumonia is caused by bacteria like Streptococcus pneumoniae and Haemophilus influenzae that infect the alveoli of the lungs, filling them with fluid and reducing respiratory efficiency. Common symptoms include fever, cough, and headache. The common cold is caused by rhinoviruses infecting the nasal passages and upper respiratory tract, causing symptoms like nasal congestion and sore throat that typically last 3-7 days. Malaria is transmitted by the bite of an infected female Anopheles mosquito, whose sporozoites enter the liver and infect red blood cells, rupturing them and releasing toxins that cause high fevers and chills in a recurring pattern.
This document discusses human health and diseases. It defines health as a state of complete physical, mental and social well-being maintained through balanced diet, hygiene and exercise. Disease is any condition that interferes with normal body functioning and causes mental distress. Diseases are classified as infectious, which can be transmitted between people, and non-infectious, which cannot. Infectious diseases are further divided into bacterial, viral, protozoan, fungal and helminthic types. Typhoid fever is caused by the Salmonella typhi bacterium transmitted through food and water, and symptoms include persistent high fever and abdominal pain.
This document contains questions about human health and diseases. It asks about abbreviations related to the immune system and diseases like AIDS. It also asks about how HIV is transmitted and the differences between cancerous and normal cells. Other questions cover metastasis, the effects of alcohol and drug abuse, carcinogens, the cell mediated immune system, malaria parasites, the life cycles of HIV and malaria, cancer diagnosis and treatment methods, CT and MRI scans for cancer detection, and why cannabinoids are banned in sports. The document also provides short sections with multiple choice questions about different lessons.
Cancer is defined as uncontrolled cell division without differentiation that can form tumors. There are two main types of tumors - benign tumors which are non-cancerous and stop growing, and malignant tumors which are cancerous and show indefinite growth and metastasis. Cancer is caused by factors like chemicals, radiation, viruses, and genes that control cell growth becoming mutated oncogenes or tumor suppressor genes being inactivated. Common cancer treatments include surgery, radiation therapy, chemotherapy, immunotherapy and targeting biological factors like interferons.
AIDS is caused by the human immunodeficiency virus (HIV) which is transmitted through sexual contact, contaminated blood transfusions, sharing infected needles, or from mother to child. HIV infects helper T-cells and macrophages, replicating within them and destroying helper T-cells. This progressively weakens the immune system and allows opportunistic infections. AIDS is diagnosed through ELISA testing and prevented through education, safe sex practices, blood screening, and treatment of infected individuals.
The document discusses active and passive immunity, vaccination and immunization, allergies, autoimmunity, and the immune system. It defines active immunity as developing due to contact with a pathogen or antigen, while passive immunity involves injecting readymade antibodies. Vaccination introduces a weakened pathogen to provide future protection, while immunization is the body's production of antibodies in response. The immune system includes primary lymphoid organs like bone marrow and thymus where lymphocytes develop and mature, and secondary organs like spleen and lymph nodes where lymphocytes interact with antigens.
This document discusses innate and acquired immunity. Innate immunity is present from birth and provides non-specific defenses like physical barriers and cellular barriers that fight pathogens. Acquired immunity develops from exposure to pathogens and produces pathogen-specific antibodies and immune cells. It has memory that allows faster responses. Acquired immunity includes humoral immunity involving B-cell produced antibodies and cell-mediated immunity involving T-cells. Antibodies are Y-shaped proteins called immunoglobulins that recognize pathogens.

The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado

This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
