Food safety vs food quality
This document discusses food safety and quality. Food safety involves preventing risks that could directly or indirectly affect consumers, such as physical, biological, chemical and radiation hazards, commercial fraud, allergens, and pests. Food quality aims to ensure food has the required acceptable characteristics to consumers, including meeting both external specifications like color, size and odor, and internal specifications such as weight, taste, flavor, and nutrition value.

Feudalism by ijaz ul-haq
Feudalism has had a stronghold on Pakistan's economy and politics since its inception. Feudal landlords control vast tracts of land and exert influence over the bureaucracy, police, and judiciary in rural areas. While feudalism is in decline in urbanizing areas, it still plagues much of rural Pakistan. Younger, educated leaders are needed to implement land reforms and curb the power of feudal elites to help modernize Pakistan's economy and political system.

Persentation on magnetometer
Magnetometers are instruments used to measure magnetic fields. There are two main types: vector magnetometers measure the direction and magnitude of magnetic fields, while scalar magnetometers measure only magnitude. Common vector magnetometer types include induction coil, fluxgate, and SQUID, while scalar types are proton precession and optically pumped. Magnetometers are used to study the Earth's magnetic field and detect magnetic anomalies. The Earth's field is generated by electric currents in the Earth's core and ionosphere. Magnetometer measurements provide information about these fields and currents.
presentation on Persimmon
Persimmons are the edible fruit surveyed in the report. They are yellowish-orange, spherical to acorn-shaped, and contain 80% water. Persimmons are harvested by hand and graded based on size, shape, and color. They are packed into cardboard boxes of 54 fruits each and may be artificially ripened with sulfur. The fruit is transported by truck, cart, and auto-rickshaw and sold through a chain from farmers to wholesalers to commission agents to retailers to consumers. Issues faced include blocked routes during snowfall, packing damage from rain, lack of price control and surveys, and payment collection problems.
Watermelon
Pakistan is generally self-sufficient in watermelon production. Watermelon is commonly consumed in Pakistan during the summer months of April, May and June as it helps reduce body heat. There are over 18 varieties of watermelon grown in Pakistan based on taste, size and color. Pakistan ranks 30th globally in watermelon production, with top producers being China, Iran, Turkey, Brazil and Egypt. Proper harvesting, handling, storage and packaging help maintain watermelon quality post-harvest.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
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).
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
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.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Phenomics assisted breeding in crop improvement
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.

Animal cell by ijaz ul-haq
- 1. Fig: Golgi apparatus structural view Animal Cell Animal Cell definition Animal cell are the basic unit of life in organism of kingdom animalia. They have true nucleus and specialized structures called organelles that carries out different functions. They don’t have cell wall. Animal Cell overview Eukaryotic cell are distinguished by the presence of nucleolus and other membrane-bound organelles. Animal cells are considered heterotrophic. They have mitochondria that are used to create ATP from various sources. Different organelles performs different functions. Animal Cell Structure Nucleus The nucleus contains a cells DNA. DNA contains instructions for making proteins which controls all the body activities. Nucleus regulates which genes are expressed in the cell, which controls cells activity and functioning depending upon the type of cell. Cell usually have one nucleus each. Cell membrane Cell membrane surrounds the entire cell. The cell membrane is a double layer made up of phospholipids. It is selectively permeable, meaning it only allows certain molecules through. This maintains homeostasis within the cell. Ribosomes Ribosomes are where proteins are synthesized. The mRNA chain travels to the ribosomes via transfer RNA (tRNA) and its sequences is used to determine the correct placement of amino acids in a chain that makes up the protein. They are found freely in cell’s cytoplasm, or attached to the membranes of the endoplasmic reticulum (ER). Mitochondria The process of cellular respiration occurs in the mitochondria. Energy is released in the form of adenosine triphosphate (ATP). ATP powers all cellular processes, and mitochondria produce a cell’s ATP, so mitochondria are commonly known as “the powerhouse of the cell”. Fig: Nucleus structural view Cytosol and all the organelles within it, except for the nucleus, are collectively referred to as a cell’s cytoplasm. The pH is generally neutral, around 7. Endoplasmic reticulum The ER is a network of membranous sacs celled cisternae. There are two kinds of ER, smooth and rough. Rough ER has ribosomes attached, smooth ER dos not have ribosomes attached an has functions in making lipids and steroids hormones and the removing toxic substances. Golgi apparatus The Golgi apparatus, also called the Golgi complex or Golgi body, is also made up of cisternae, but the cisternae are not interconnected like those of the ER. The Golgi apparatus receives proteins from the ER and folds, sorts, and packages these proteins into vesicles. Vesicles They are used for transporting molecules throughout the cell from one organelle to another and are also involved in metabolism. Specialized vesicles called lysosomes contain enzymes that digest large molecules like carbohydrates, lipids, and proteins into smaller ones. Cytoskeleton The cytoskeleton is a network of filaments and tubules found throughout the cytoplasm of the cell. It has many functions: it gives the cell shape, provides strength, and stabilizes tissues. There are three types of cytoskeletal filaments: microfilaments, microtubules, and intermediate filaments.
