wing is one of the most characterstic feature of insects.
In majority of insects mesothorax and meta thorax carries a pair of wings.
On the basis of presence of wings class insecta is devided into 2 sub classes :
1. APTERIGOTA
2. PTERIGOTA

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.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
DERIVATION OF MODIFIED BERNOULLI EQUATION WITH VISCOUS EFFECTS AND TERMINAL V...Wasswaderrick3
In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.

3. Insect Nervous system
The basic component is the nerve cell, or neuron (neurone), composed of a cell
body with two projections (fibers):
1. The dendrite, which receives stimuli.
2. The axon, which transmits information, either to another neuron or to an
effector organ such as a muscle.
Insect neurons release a variety of chemical at synapses to either stimulate or
inhibit effector neurons or muscles.
In common with vertebrates, particularly important neurotransmitters include
acetylcholine and catecholamines.
4. Type of neuron
1. Sensory neurons:
Receive stimuli from the insect’s environment and transmit them to the central
nervous system.
2. Interneurons (or association neurons):
Receive information from and transmit it to other neurons.
3. Motor neurons:
Receive information from interneurons and transmit it to muscles.
4. neuroendocrine cells:
The cell bodies of interneurons and motor neurons are aggregated with the
fibers interconnecting all types of nerve cells to form nerve centers called
ganglia.
5. Diagram of a simple reflex mechanism of an insect.
The arrows show the paths of nerve impulses along nerve fibers (axons and dendrites).
6. The insect nervous system
1. Central nervous system.
2. Visceral nervous system.
3. Peripheral nervous system.
7. 1. Central nervous system
The central nervous system (CNS) is the principal division
of the nervous system and consists of series of ganglia
joined by paired longitudinal nerve cords called
connectives.
Primitively there are a pair of ganglia per body segment
The ganglia of all head segments are coalesced to form two
ganglionic centers:
The brain and the suboesophageal (subesophageal)
ganglion.
The chain of thoracic and abdominal ganglia found on the
floor of the body cavity is called the ventral nerve cord.
8. The brain
The brain, or the dorsal ganglionic center of the head, is composed of three
pairs of fused ganglia (from the first three head segments):
1. protocerebrum:
Associated with the eyes and thus bearing the optic lobes;
2. Deutocerebrum:
Innervating the antennae
3. Tritocerebrum:
Concerned with handling the signals that arrive from the body.
9. 2. Visceral nervous system
Consists of three subsystems:
1. The stomodeal (or stomatogastric)
which includes the frontal ganglion.
2. The ventral visceral
3.The caudal visceral.
Together the nerves and ganglia of these subsystems innervate the anterior
and posterior gut, several endocrine organs, the reproductive organs, and the
tracheal system including the spiracles.
10. 3. The peripheral nervous system
Consists of:
1. All of the motor neuron axons that radiate to the muscles from the
ganglia of the CNS, stomodeal nervous system.
2. The sensory neurons of the cuticular sensory structures (the sense
organs) that receive mechanical, chemical, thermal, or visual stimuli from
an insect’s environment.
