This document describes an experiment to observe how blood circulation is affected by gravity. Students measured the circumference of the neck and ankles of classmates in different body positions - standing, lying down, and standing upside down. Preliminary results from Italian students showed the neck was larger when lying down and ankles were smaller, indicating blood flows differently due to gravity. The conclusion is that in space without gravity, blood spreads equally throughout the body, while on Earth it is pulled downwards.

Circulation of the blood and optical nerve
1) The experiment measured the circumference of participants' necks and ankles in different body positions to simulate how blood circulates differently in space without gravity.
2) When standing, the neck circumference was smaller and ankle circumference was larger compared to lying down, due to more blood pooling in the legs with gravity. Upside down, more blood rose to the head.
3) The results supported the hypothesis that less blood in the head in space could cause pressure on the optical nerve, explaining why astronauts see flashes of light.

This document summarizes an experiment measuring blood circulation and its effects on the optic nerve. Students measured the circumference of their necks and ankles while standing, lying down, and hanging upside down. Regardless of position, neck measurements increased while upside down while ankle measurements decreased. This is because without gravity in space, blood spreads equally throughout the body, increasing pressure on the brain and optic nerve. On Earth, gravity causes more blood to pool in the ankles while standing and spread throughout the body when lying down.

The Integrated Spring-Mass Approach to Treating Thoracic Outlet Syndrome
Presented at the Florida Chiropractic Physicians Association Conference in Orlando Florida in 2015
by Dr James Stoxen DC, FSSEMM (hon)
If you have headaches, neck pain, upper back or shoulder pain, you may have thoracic outlet syndrome.
As a syndrome rather than a disease, TOS produces a variety of symptoms that suggest underlying causes, rather pointing directly to a specific ailment. These, atypical symptoms, are the result of persistent compression of nerves, arteries and veins traveling through the thoracic outlet and tunnel.
The thoracic outlet, inlet or compartment is a tunnel located under the shoulder and over the rib cage, where the artery, vein and nerves pass from the chest and neck area into the arm and hand.
It is one of the most underrated, overlooked and misdiagnosed conditions and proves difficult to manage. Medical professionals appreciate that it is probably the most important peripheral nerve compression in the upper extremity. (1)
Thoracic outlet syndrome (TOS) is a complicated disorder and generates great medical controversy.
In this presentation I discuss the Integrated Spring-Mass Approach to examination, treatment and prevention of thoracic outlet syndrome. eTwinning biology skeleton 3WETab
The document summarizes an experiment about how the human skeleton is affected by the absence of gravity in space. The experiment involved soaking chicken leg bones in acid to simulate the bone loss that occurs in astronauts. It also used cardboard with and without holes to demonstrate how bones and tissues deteriorate in space. The results showed that acid-soaked bones and cardboard with holes broke and tore more easily, mirroring the bone and muscle loss astronauts experience without exercise in the weightlessness of space.
Grounding
The document discusses how humans are bioelectrical beings that are naturally grounded through contact with the Earth. It explains that the Earth acts as a giant battery that we have become disconnected from due to modern lifestyles. Being grounded or "earthing" provides health benefits by reducing inflammation and balancing the nervous system. Various techniques are presented for reconnecting to the Earth's natural electrons, such as going barefoot outside, using grounding mats indoors, and engaging in mindful activities like walking or yoga to feel the connection to the ground. Research supports the health impacts of reconnecting to this untapped resource.

The document summarizes an experiment conducted by students in Belgium and Italy to understand why astronauts experience space sickness, also known as space adaptation syndrome. The students in each country performed experiments spinning themselves and then trying to walk or stand in various conditions with their eyes open or closed. Both groups found it was difficult to balance after spinning. The Belgian students concluded that space sickness occurs because the balance system and eyes provide different signals to the brain. The Italian students concluded that the body experiences nausea to find a way to improve its condition and throw up any potential poisons.

Biology a chapter two powerpoint
Homeostasis refers to the maintenance of a constant internal environment in the body. The body has mechanisms to keep key conditions like temperature, water levels, and glucose concentration within normal ranges to allow cells to function properly. Diseases and stress can disrupt homeostasis by affecting these regulatory mechanisms. The metric system provides a logical and consistent way to measure quantities in science by using prefixes that denote multiples of ten for units of length, volume, and mass. Microscopes allow observation of microscopic structures and organisms by magnifying small objects. The amount of magnification is determined by multiplying the powers of the ocular and objective lenses.

Rigor mortis ppt
Rigor mortis is the stiffening of muscles after death. It begins in involuntary muscles within 1-2 hours, then spreads to voluntary muscles over 6-12 hours. Maximum rigor is reached at 12 hours and passes off over the next 12 hours. It is caused by depletion of ATP and influx of calcium ions into muscles. Rigor mortis can help determine time and position of death, and distinguish ante-mortem from post-mortem injuries. It may be simulated by heat stiffening, cold stiffening, or cadaveric spasm at the moment of death. A case study described rigor mortis revealing an unusual body position, indicating the crime scene differed from where the body was discovered.
Cellebelar
The cerebellum is involved in coordinating movement, balance, and muscle tone. It compares intended movements with feedback from the limbs to correct movements if needed. Disorders can cause ataxia, which affects balance and coordination. On examination, this may appear as abnormal gait, finger-pointing difficulties, or positive tests like Romberg's sign of increased sway with eyes closed. Other signs include intention tremor, nystagmus, dysmetria, and dysdiadochokinesis.
Human Physiology and Anatomy in Space 2013
This document discusses the physiological effects of microgravity on the human body during spaceflight. It notes that in microgravity, fluids shift upwards causing face and head swelling, dehydration occurs as kidneys eliminate excess fluids, muscles and bones weaken due to lack of weight-bearing activity, and the heart shrinks as it doesn't need to work as hard. Precautions like exercise and lower body negative pressure are used to counter these effects. Prolonged microgravity exposure can lead to long-term health issues, so further research is still needed on its impacts and ways to minimize risks to support future long-duration space missions.

Spondylitis is a condition caused by inflammation of the vertebrae in the spinal cord. This leads the vertebral joints to become inflamed and causes the vertebrae to grow or fuse together, resulting in a rigid spine. The pain may not be felt initially but gradually worsens as the condition progresses, usually starting in the lower back and moving upwards. Spondylitis is commonly caused by genetics, as over 90% of people with the condition carry a particular gene, and having a family history increases risk.

This document defines cephalopelvic disproportion and describes factors that can influence pelvic size. It discusses various types of contracted pelves, including developmental, metabolic, and traumatic causes. Methods for diagnosing a contracted pelvis are provided, including history, examination, and pelvimetry techniques. Degrees of disproportion and contracted pelvis are defined based on pelvic measurements.
COMA 2.2.pptx
1. Coma is a state of unresponsiveness in which patients fail to arouse even with vigorous stimulation. It can result from diffuse brain disturbances, large supratentorial lesions, or direct damage to the brainstem.
2. The Glasgow Coma Scale is used to assess a patient's level of consciousness by evaluating eye opening, motor response, and verbal response.
3. Causes of coma include metabolic disturbances, toxins/drugs, infections, vascular issues, trauma, and epilepsy. Common causes are hypoglycemia, hypoxia, drugs/alcohol, and subarachnoid hemorrhage.
Craniosacral Inservice
Craniosacral therapy was developed in the late 19th century by William Garner Sutherland who believed that the bones of the skull were capable of subtle movement, in contrast to accepted anatomical views. John Upledger later expanded on Sutherland's work in the 1970s. Craniosacral therapy involves gentle palpation to detect and manipulate the cranial bones and release restrictions in the craniosacral system to support health and healing. While some research studies show promise for reducing migraine symptoms, the subtle and variable nature of craniosacral therapy makes it difficult to study and research results are mixed.
Bodylength 2
Two student groups from France and Belgium conducted an experiment to understand how body length changes in space compared to on Earth. They measured the body lengths of students both standing up and laying down, and found that stretching before measuring increased length. Their conclusion was that people appear taller in space than on Earth because gravity does not pull limbs downwards, and laying down results in a longer body length than standing up due to the effects of gravity.

The heart and lungs
This document provides information about the heart and lungs. It discusses what each organ does, key facts about their structure and function, and how to keep them healthy. The heart pumps blood through the body and beats faster with exercise. The lungs exchange oxygen and carbon dioxide as we breathe. Maintaining a healthy heart and lungs involves regular exercise and avoiding smoking.
Homeostasis of the body
The document discusses homeostasis, which refers to the body's ability to maintain stable internal conditions such as temperature, water levels, and glucose concentration. It does this through various mechanisms. For temperature regulation, the body uses sweating and vasodilation/vasoconstriction to cool down or warm up. Insulin and glucagon work to regulate glucose levels. The kidneys control water levels and remove waste like urea through urine production and excretion. Together, these mechanisms allow the body to maintain homeostasis.
Cardiovascular assessment
1) The document reviews the anatomy and physiology of the cardiovascular system and describes methods for assessing cardiovascular status including health history, physical exam techniques like inspection, palpation, percussion and auscultation, and diagnostic tests.
2) The physical exam involves assessing things like vital signs, jugular vein pulsations, heart sounds and murmurs auscultated over the precordium.
3) Diagnostic tests discussed include electrocardiograms, echocardiograms, stress tests and cardiac catheterization.
Q1-Lesson 2-Coordinated Functions Of Restpiratory and Circulatory System.pptx
The document discusses the coordinated functions of the respiratory and circulatory systems. It describes how oxygen is absorbed from the lungs into the blood and carried throughout the body by the circulatory system, while carbon dioxide is transported from tissues to the lungs to be released. The respiratory and circulatory systems work together to oxygenate blood in the lungs and transport it to tissues to support cellular respiration before returning deoxygenated blood to the lungs to repeat the cycle.

This document presents six arguments for why God may exist. First, it argues that the complexity and design of our planet, including its size, distance from the sun, moon, water, human brain, and eye, point to an intelligent designer. Second, it claims that the Big Bang that started the universe requires a cause. Third, it questions why the universe operates based on consistent, uniform laws of nature.
Asphyxia.pptx
Asphyxia refers to a condition where cells or organs do not receive enough oxygen. It can be partial (hypoxia) or total (anoxia). There are four main types of anoxia: anoxic, stagnant, anaemic, and histotoxic. Hanging, strangulation, and drowning are three common forms of violent asphyxia that can cause death. In a hanging, the weight of the body constricts the neck, while in strangulation an object other than the body applies pressure. Drowning occurs when fluid prevents air from entering the lungs. Autopsies of asphyxia victims examine for signs like petechial hemorrhages, visceral congestion, and
Neurological assessment ppt by heena mehta
The document provides guidance on performing a neurological examination. It outlines assessing the cranial nerves, reflexes, motor system, and sensory system. The cranial nerve examination involves testing each nerve individually. Reflex testing grades reflexes on a scale from 0 to 4. The motor exam evaluates muscle strength on a scale from 0 to 5. Finally, the sensory exam tests sensations like pain, touch, and position sense. The goal is to identify which parts of the neurological system may be affected.

2) They tested identifying foods like carrots, crackers and chocolate while blindfolded with and without blocking their nose, and identifying chocolate while smelling onions.
3) Their results found that blocking the nose made identifying foods more difficult, but they could still taste foods to some degree, and that strong smells like onions interfered with identifying foods by taste.
eTwinning biology muscles 3WETab
This document describes an experiment about how astronauts have trouble standing and walking when they return to Earth from space. The experiment involves measuring a person's mass when standing and lying down to show that muscles are needed to apply force against gravity. When astronauts spend time in space's microgravity, their muscles weaken from disuse and have trouble supporting their body weight on Earth, causing them to collapse initially until their muscles regain strength.

Second, it claims that the Big Bang that started the universe requires a cause. Third, it questions why the universe operates based on consistent, uniform laws of nature.
Asphyxia.pptx
Asphyxia refers to a condition where cells or organs do not receive enough oxygen. It can be partial (hypoxia) or total (anoxia). There are four main types of anoxia: anoxic, stagnant, anaemic, and histotoxic. Hanging, strangulation, and drowning are three common forms of violent asphyxia that can cause death. In a hanging, the weight of the body constricts the neck, while in strangulation an object other than the body applies pressure. Drowning occurs when fluid prevents air from entering the lungs. Autopsies of asphyxia victims examine for signs like petechial hemorrhages, visceral congestion, and
Neurological assessment ppt by heena mehta
The document provides guidance on performing a neurological examination. It outlines assessing the cranial nerves, reflexes, motor system, and sensory system. The cranial nerve examination involves testing each nerve individually. Reflex testing grades reflexes on a scale from 0 to 4. The motor exam evaluates muscle strength on a scale from 0 to 5. Finally, the sensory exam tests sensations like pain, touch, and position sense. The goal is to identify which parts of the neurological system may be affected.

eTwinning biology taste 3WETab
1) Italian girls Martina and Greta and Belgian boys Tobie and Wout conducted experiments on taste and smell using foods while blindfolded.
2) They tested identifying foods like carrots, crackers and chocolate while blindfolded with and without blocking their nose, and identifying chocolate while smelling onions.
3) Their results found that blocking the nose made identifying foods more difficult, but they could still taste foods to some degree, and that strong smells like onions interfered with identifying foods by taste.
eTwinning biology muscles 3WETab
This document describes an experiment about how astronauts have trouble standing and walking when they return to Earth from space. The experiment involves measuring a person's mass when standing and lying down to show that muscles are needed to apply force against gravity. When astronauts spend time in space's microgravity, their muscles weaken from disuse and have trouble supporting their body weight on Earth, causing them to collapse initially until their muscles regain strength.
eTwinning biology bodylength 3WETab
1) A group of students measured their body length both standing up and lying down, as well as their mass, to understand why NASA makes spacesuits longer than necessary for the body length on Earth.
2) Their results showed that body length increased slightly when lying down compared to standing up, with the percentage difference in length being lower for students with higher mass.
3) Comparing their results to those of students in Italy, they found that the percentage difference in body length was generally lower for students with higher mass, and that lying down makes one "taller" due to the effects of gravity.
eTwinning biology taste 3WETc
The document describes an experiment where participants were blindfolded and given different foods to taste while smelling other scents. They first ate chocolate while smelling onions, finding it difficult to taste the chocolate. Next they ate grapes while smelling onions again, which made it even harder to taste. They concluded that smell influences taste, so smelling one food makes it challenging to identify the taste of another food being eaten.
eTwinning biology muscles 3WETc
1) The document describes an experiment measuring muscle force standing up versus lying down. Students measured their weight standing and then pushing against a wall-mounted scale while lying on their backs.
2) The results showed students could exert less force on the scale when lying down compared to standing. One student pushed with 7kg of force lying down versus 55kg standing.
3) The conclusion is that it is more difficult to exert force while lying down due to muscles being used less in that position. The explanation discusses how astronauts' muscles atrophy in space due to less gravity usage.
eTwinning biology skeleton 3WETc
1) Astronauts are more likely to develop osteoporosis than others because living in a low-gravity environment in space causes bone mass to decrease over time due to carrying less weight.
2) An experiment showed that a normal chicken leg was harder to break than one that had been soaked in acid, demonstrating that healthier bone is stronger. Similarly, perforated cardboard ripped easier than solid cardboard.
3) The conclusions were that astronauts' bone mass decreases in space without gravity, making their bones weaker, and that they have a higher risk of osteoporosis and bone fractures when returning to Earth gravity.

THEMATIC APPERCEPTION TEST(TAT) cognitive abilities, creativity, and critic...Abdul Wali Khan University Mardan,kP,Pakistan
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsApplied 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 binding of cosmological structures by massless topological defects
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).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).
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.
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.

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.
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.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
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.

- 1. CIRCULATION OF THE BLOOD AND THE OPTICAL NERVE Alessia Poggioli Ludovica Rocchi Leentje Clement Xenia Cordonnier 1
- 2. MATERIALS To make this experiment, you just need: • a tape measure • a person • a person who takes the measures to the other one. The objective is to discover how the blood acts in the body on the Earth. 2
- 3. HOW TO MAKE THE EXPERIMENT Firstly, a person has to measure the circumference of the ankles and the neck while the other one is standing up. Secondly, the same person has to measure the same circumferences while the other person is laying down. Thirdly, the person has to measure the circumference of the ankles and the neck while the other one is standing upside down. Finally, compare all the results obtained. 3

- 5. ITALIAN EXPERIMENT Standing up Laying down Standing upside down Circumference of the neck (cm) 38 40.5 43 Circumference of the ankles (cm) 24 23.5 23 BELGIUM EXPERIMENT Standing up Laying down Standing upside down Circumference of the neck (cm) Circumference of the ankles (cm) RESULTS AND REMARKS 5
- 6. In space, in absence of gravity, the blood is spread equally all over the body. For this reason, the pressure of the blood around the brain is transmitted along the optical nerve into the eye and it increases the pressure of the eye causing flashes of light. In addiction, the flashes can also be produced by cosmic rays. Otherwise, on the Earth the circulation of blood behaves in a different way because of gravity. In fact, standing up the blood is attracted to the middle of the Earth, it is more concentrated in the ankles than in the neck. Instead, laying down the blood spreads all over the body, so the circumference of the neck increases while the circumference of the ankles decreases. 6
- 7. We don’t know anything about space because we have never studied it, but doing this experiment we learnt that the blood acts according to the gravity. So, it makes sense that the blood spreads equally all over the body in the space. REFLECTION 7
- 8. CONCLUSION • On the Earth, the blood is attracted down by the gravity. • In space, the blood spreads all over the body because there’s no gravity. • In fact, the blood rushes to the head more than normal. • Consequently, blood in the head presses on the optical nerve. • Impulses of lights go straight to the brain. 8
