All astronomical bodies originate inside clouds of gas and dust, therefore there should be a common process that leads to
their condensation. In a galactic cloud there is always a gradient of speeds from point to point. Thanks to it, vortices originate
that rake the material of the surrounding cloud gradually forming large gaseous disks, inside which vortices of second order
develop that concentrate the matter of their orbits forming smaller and much denser disks, within which third order vortices
further concentrate the matter. The dense cores of these vortices finally condense in massive bodies: sun, planets and satellites.
The result should be a well ordered planetary system with no “debris” around and where both planets and satellites obey to
a precise rule of the distances from their central body. The solar system complies with these conditions with three main
exceptions. First, in an orbit where a large planet should be there is only a huge number of scattered asteroids. Second, Earth
and its moon with all evidence were not formed in the same vortex, which means that Moon originated somewhere else. Third,
Neptune’s satellite system has been shattered by the intrusion of a foreign body, Triton, and its largest satellites are missing.
These exceptions seem to be strictly connected to each other and all due to a unique event, that is: Triton has diverted the
largest Neptune satellite towards the Sun. This satellite impacted at high speed against the missing planet, scattering myriads
of fragments from its mantle and pushing it towards the sun, where it eventually fell. The planet had at least 4 satellites some
of which remained in their previous orbit, but two of them were dragged towards the sun and were captured by Earth. The
largest became its lonely moon while the second fell on its surface giving origin to the continents. This event happened about
3,96 billion of years ago, as it is proven by the ages of the numerous samples brought from the moon
The document summarizes the evolution of Earth from its formation to present day. It describes how:
- Dust and gas coalesced from the solar nebula to form planetesimals and eventually Earth around 4.5 billion years ago.
- Early Earth was mostly molten due to heavy bombardment and radioactive decay. The heat allowed the planet to differentiate into a core, mantle, and crust.
- As Earth cooled, water and an atmosphere formed. Photosynthetic life evolved and increased oxygen in the atmosphere around 2.4 billion years ago.
- Plate tectonics and volcanism have continuously recycled Earth's crust and regulated temperatures and atmospheric gases through geologic time.
1. James Hutton established the theory of uniformitarianism, which states that the geological forces shaping Earth today are the same as in the past. He is considered the founder of modern geology.
2. Charles Darwin developed the theory of evolution through natural selection, which explained how species change over time in response to their environment.
3. Andrija Mohorovicic discovered the boundary between Earth's crust and mantle, known as the Mohorovicic discontinuity or "Moho".
4. Beno Gutenberg studied earthquakes and discovered that their waves can be used to investigate Earth's internal structure
The document discusses several theories on the origin of the universe:
- The Steady State Theory proposed the universe has always and will always remain the same.
- The Oscillating Universe Theory proposed the universe exists in a cycle of big bangs and big crunches.
- The Eternal Inflation Theory proposes inflation never stops after the big bang.
- For the formation of the solar system, theories included the Nebular Hypothesis of a collapsing cloud forming the sun and planets, and the Condensation Theory of dust accumulating in the solar nebula.

The document provides information about the universe and solar system. It discusses:
- The universe is approximately 13.8 billion years old and consists of dark energy, dark matter, and normal matter.
- The solar system formed from a collapsing cloud of gas and dust around the sun approximately 4.6 billion years ago. Planetesimals collided and accreted to form the planets.
- The current model is that the sun and planets formed from a protoplanetary disk, with collisions forming the terrestrial planets close to the sun and condensation forming the gas giants further out.
This document discusses the field of geology. It defines geology as the study of the Earth, including its physical and chemical properties from its creation to present day. The main branches of geology are described as crystallography, mineralogy, petrology, paleontology, and stratigraphy. The layers of the Earth are also summarized, including the inner core, outer core, mantle, and crust. Finally, several hypotheses for the origin of the Earth are outlined, such as the nebular hypothesis, planetesimal hypothesis, gaseous tidal hypothesis, and gas dust cloud hypothesis.
Gravity is the force that attracts all matter to each other. It causes planets, stars, and galaxies to form and influences the motion of objects in space. Isaac Newton first proposed that gravity depends on the masses of objects and the distance between them. Later, Einstein's theory of general relativity explained that gravity is caused by the curvature of spacetime due to the uneven distribution of mass. Tests have supported Einstein's theory, such as observations of gravitational lensing and gravitational waves. Gravity plays a key role in the formation and evolution of astronomical objects throughout the universe.
Jack Oughton - Galaxy Formation Journal 02.docJack Oughton
1) The document discusses theories of galaxy formation from the early universe following the Big Bang.
2) It describes the top-down and bottom-up theories of galaxy formation, where top-down suggests the first objects to form were large irregular structures that later broke apart, and bottom-up suggests smaller dense areas first combined together to form galaxies.
3) The author argues the bottom-up theory of smaller areas hierarchically clustering together is most credible given current evidence of hierarchical clustering in the universe, but knowledge in this area remains limited.
According to the nebular hypothesis:
- The Sun and planets formed from a giant cloud of dust and gas that collapsed due to some event around 4.57 billion years ago.
- As the cloud collapsed and began rotating faster, it flattened into a disk with the Sun forming at the center.
- The terrestrial planets like Earth formed closer to the Sun from metals and rocks, while the gas giants formed beyond the frost line where ices could also form, allowing them to grow larger.
- Leftover debris that did not form planets remains in regions like the Asteroid Belt and Kuiper Belt today.

Galactic Context
The Solar System is located in the Milky Way galaxy, a barred spiral galaxy with a diameter of about 100,000 light-years containing about 200 billion stars. Our Sun resides in one of the Milky Way's outer spiral arms, known as the Orion Arm or Local Spur. The Sun lies between 25,000 and 28,000 light years from the Galactic Centre, and its speed within the galaxy is about 220 kilometres per second, so that it completes one revolution every 225–250 million years. This revolution is known as the Solar System's galactic year. The solar apex, the direction of the Sun's path through interstellar space, is near the constellation of Hercules in the direction of the current location of the bright star Vega. The plane of the Solar System's ecliptic lies nearly at right angles (86.5°) to the galactic plane.

The document also notes open questions in quantum gravity and efforts to develop a unified theory reconciling general relativity and quantum mechanics.
Theories on the origin of the Solar SystemJerome Bigael
The document discusses theories on the origin of the solar system. It begins by describing the basic composition of the solar system, including stars, planets, natural satellites, comets, asteroids, and the interplanetary medium. It then discusses several theories for how the solar system formed, including:
- The nebular hypothesis proposed in the 1700s that a rotating gaseous cloud contracted to form the sun and planets from the surrounding disc. However, it did not fully explain the distribution of angular momentum.
- Encounter hypotheses proposed interactions between stars caused matter to be drawn off and form planets, but cannot explain the different ages of the sun and planets.
- The currently accepted protoplanet
The document discusses the solar system from a broader perspective. It provides details on the formation of the solar system based on the nebular hypothesis, including how planets formed from a rotating cloud of gas and dust. It also describes the different types of objects in the solar system such as the terrestrial and gas planets, asteroids, comets, and Pluto. Additionally, it discusses theories for the origin of the Moon and evidence that Mars once had liquid water on its surface.
This document proposes a theory for the origin of the solar system. The theory belongs to the dualistic class of theories but retains aspects of monistic theories. It emphasizes that an instability in the boundary layer of the solar nebula could occur if a foreign body, such as a brother star of the Sun, approached the nebula. This instability could cause the boundary layer to split off into a rotating gas ring, forming the first planet. The theory derives a law of planetary distances from the Sun that is obeyed more closely than the Titius-Bode law. This law may also apply to satellite systems around other planets.

The solar system formed 4.6 billion years ago from a cloud of gas and dust left over from exploded stars. Over time, the cloud contracted due to gravity, causing the center to heat up and form the Sun. A rotating disc of debris remaining around the Sun eventually coalesced under gravity to form the planets. The inner rocky planets like Earth formed close to the Sun, while the outer gas giants like Jupiter were able to capture lighter gases further from the Sun.

Stars form from clouds of dust and gas that collapse under their own gravity. As the cloud collapses, a hot protostar forms at the center. Nearby clouds may break into blobs, explaining why most stars exist in pairs or groups. Planets form from disks of dust and gas that surround young stars. As the disk spins, dust clumps stick together, growing into planetesimals that eventually collide and merge into planets. Moons can form alongside planets from leftover material, be captured asteroids, or form from debris after a large impact. Eventually the sun will run out of hydrogen fuel and expand into a red giant, likely consuming the inner planets before collapsing into a white dwarf.
The universe contains billions of galaxies, each with billions of stars. A galaxy is a group of stars held together by gravity, and there are three main types of galaxies: spiral, elliptical, and irregular. Stars are formed from the collapse of large clouds of dust and gas under the force of gravity. Our solar system contains eight planets that orbit the Sun, including Earth. Copernicus first proposed that planets orbit the Sun, while Kepler developed the three laws of planetary motion describing their elliptical orbits and periods.

This article aims to present the origin and evolution of Universe, Sun and Earth as well as alternative solutions for the survival of humanity with the end of Earth planet, Sun and Universe.
The Big Bang model postulates that the universe began as a hot dense state around 13.8 billion years ago and has since expanded and cooled. It is supported by two theoretical pillars: general relativity, which describes gravity as the curvature of spacetime, and the cosmological principle that the universe is homogeneous and isotropic on large scales. The model accounts for the cosmic microwave background radiation and expansion of the universe, but is incomplete as it does not explain structure formation or the universe's uniformity on the largest scales.
Unit vi chapter 24 (stars, space and galaxies)evrttexohrt10
1) Stars originate from nebulae of dust and gas. They spend most of their life fusing hydrogen into helium through nuclear fusion in their cores as main sequence stars.
2) When stars have exhausted their hydrogen, their cores collapse and outer layers expand, forming red giants. More massive stars explode as supernovae, leaving behind neutron stars or black holes.
3) The sun is classified as a yellow dwarf star. Its atmosphere consists of the photosphere, chromosphere, and corona. Nuclear fusion in its core provides its energy.
The document summarizes problems that emerged with the Big Bang theory starting in the 1970s-1980s. Observational evidence showed:
1) Galaxies rotated too fast based on visible matter, implying 90% of matter is "dark matter".
2) The cosmic microwave background was too uniform across distances light could not have traveled, the "horizon problem".
3) The universe appeared "flat" requiring impossibly precise conditions shortly after the Big Bang.
4) Distant quasars existed too early, inconsistent with the universe's evolution. This "crisis in cosmology" suggested the Big Bang theory needed replacing.
Background: Intracoronary fibrinolytic administration immediately after primary PCI improves microvascular perfusion,
decreases long-term infarct size, and improves LV function especially in patients with superimposed thrombus. As a
consequence intracoronary thrombolytic is considered one of the pharmacological strategies for management of high
thrombus burden lesions during PCI.
Objectives: To assess the effect of low dose intracoronary streptokinase (ICSK) during primary PCI in patients presenting
with acute anterior wall S-T segment elevation myocardial infarction with a definite thrombus in the left anterior descending
artery on clinical, angiographic and echocardiographic outcomes.
Methods: A total of 167 patients at the National Heart Institute, Egypt who had undergone primary PCI following an acute
anterior wall STEMI presentation were included in this randomised controlled study (with a thrombus grading > thrombus
grade 2) and no history of coronary angioplasty or myocardial infarction of the LADs. Patients were randomized into two
groups: a control group (n = 90) receiving no extra therapy, and a study group (n = 77) receiving ICSK during primary PCI.
Following PCI, angiographic results and S-T segment resolution were evaluated. A follow-up of MACE and echocardiographic
results was subsequently carried out at 6 and 12 months.
Results: Post-PCI indices of perfusion, such as TIMI flow grade 3 (79% vs. 51%), MBG 3 (43% vs. 20%), and cTFC (18.20 ±
4.01 vs. 30.95 ± 3.75), were considerably better in the ICSK group than in the control group. The ICSK group’s SWMA index
score was substantially lower than that of the control group on the 6- and 12-month follow-ups (1.01 ± 0.02 vs 1.28 ± 0.04, and
1.22 ± 0.11 vs 1.7 ± 0.06, respectively).
Conclusion: The use of low dose ICSK during primary PCI in acute anterior STEMI patients with coronary thrombi enhanced
coronary perfusion and LV function, presenting a favorable approach for managing high thrombus burden PCI.
In forensic practice, PRIS is considered as the comorbid disease. The project was devoted to the study of PRIS signs in 38 cases
of sudden death after surgical interventions. Archival forensic material of “medical cases” for the period from 2011 to 2020
was studied. The clinical and laboratory features of PRIS are summarized. It was found that the most common symptoms were
lactic acidosis, hyperkalemia, and progressive heart failure. Optimization of standard forensic chemical study was carried
out, in which it was established that the hydrolysis stage must be included in the urine sample preparation procedure for
the determination of propofol. When conducting forensic chemical study of biological objects for the content of propofol, the
analytical technologies used must have the sensitivity for detecting propofol in the blood at the level of 0.01 μg/ml or lower.
Solid-phase extraction method on cartridges with mixed hydrophobic-anion exchange properties with sorbent such as Oasis
MAX Cartridge 3cc, /60 mg/60μm companies Waters (USA) is 17% more effective than the routine liquid-liquid extraction
method of propofol from blood. The preparation of TMS derivatives of propofol, increases the efficiency of chromatographic
separation and provides the possibility for the analytical study of extracts from blood over a longer period of time (up to 24 hours).

Chronic Renal Failure (CRF), a progressive, irreversible deterioration in renal function in which the body’s ability to sustain
metabolic and fluid and electrolyte balance fails, resulting in uremia or azotemia, is a global public health problem that tends to
take dimensions of epidemic and has severe impact on quality of patient’s life. Chronic kidney diseases represent a noteworthy
health problem across the globe with CRF. The clear-cut prevalence of CRF worldwide was obscure due to the clinical
continuum ranging from indolent, asymptomatic to complete renal decompensation. Thus, continual inputs through a series
of research considering various conventional and certain earlier techniques in background, along this thrust medical area, led
an emerging and medically most precise technique, namely, Electro-homeopathic therapy that has been currently in practice
by a number of practitioners in India revealing fascinating outcome without any significant post therapeutic physiological
and/or biochemical side effect as well as risk factor. The efficacy of the Electro-homoeopathy treatment for chronic kidney
disease has been successfully monitored over a period of 30-60 and 30-80 days, respectively, in the case of GFR and renal
lithiasis, based on improvement in the subjective parameters and blood investigations. Nevertheless, paralysis of bladder
cases was cured within 30 to 60 days of treatment. The outcome of this overview provides new insights into developing and
establishing more and more advanced account of Electro-Homeopathic system for accurate diagnosis enlightening specific
root cause/origin (Etiology) and smooth-running management of ‘Chronic Renal Failure’ as well as its manifestation.
Objective: To determine both tubotympanic and atticoantral disease in active chronic otitis media. To identify the
microbiological species that cause these two categories, as well as their sensitive medications, by culture and sensitivity
testing.
Methods: This was a prospective observational cross-sectional study conducted on Fifty Chronic otitis media patients from
the Department of Otorhinolaryngology at Jaipur National University during November 2021 to October 2023. An assessment
of the clinical presentation and course of Chronic otitis media and analysis of the microbiological etiology of the disease was
done. Clinical assessment included history taking, physical examination, and audiometric testing. Microbiological analysis
included culture and susceptibility testing and molecular testing.
Results: Fifty Chronic otitis media patients were included in the study and studied over the course of two years. There were
22 males and 28 females. The most common bacterial etiologies of Chronic otitis media were Streptococcus pneumoniae,
Pseudomonas aeruginosa, and Staphylococcus aureus. A mucopurulent type of discharge was seen in most pseudomonas
infections (50%). Acinetobacter (100%) and Staphylococcus (75%) both mostly discharged mucopurulent material.
Conclusion: These results provide insight into the management of Chronic otitis media and highlight the importance of proper
diagnosis and treatment of the condition.
Banks are directly affected by macroeconomic factors in China, with changes in these factors significantly impacting bank stock prices and the banks' operations and management. Due to differences in capital attributes, state-owned banks and non-stateowned banks exhibit various micro-level differences, leading to different reactions in their stock prices to macroeconomic changes. Consequently, the investment value analysis for banks with different attributes also differs. This paper conducts an empirical analysis of the investment value of bank stocks, primarily following these steps: first, conducting factor analysis on cross-sectional data to calculate the total variance explained by the factor analysis and the factor scores; second, calculating the common factors and composite scores for each quarter; and finally, using panel data and the improved TOPSIS-based factor analysis model to evaluate the stock investment value of 16 banks for the first, second, and third quarters of 2022. The results indicate a disparity in investment value between state-owned and non-state-owned banks, with an overall imbalance in investment value among these banks.
With the discovery of “Pulsar” a new probe of short duration radio pulses arises to the astronomers. Searching the “tomography”
of the galaxy using the short-pulses offered a new method to measure the fairly accurate distance to the new sources of pulse
radiation i.e. Pulsars. Another pulse radiative object i.e. fast radio burst (FRB) remains a mysterious object till today. Analysis
of observed data indicates that FRBs have multi-source origin, variation in location of the burst generation (i.e. radial distance
from their central compact objects, the Magnetar’s surface) depending on model to model. Two most important puzzle creating
facts of FRBs are: (a) microstructure appearance in FRBs on time-scale of ≤ 10 μs; (b) No FRBs observed at low latitudes.
Recoding of observed parameters from Cosmic Baby, i.e. Swift J1818.0 – 1607, shows that it has a steep spectra at first and
then flat spectra later which indicates possibly be a transient object between normal pulsars and magnetars. This unusual
characteristic of radio spectrum provides a clue to rethink about the magnetar origin of FRBS. i.e. Cosmic Baby can be a probe
of resolving the mangetar originated FRB problem.
The author thus encourages the radio wave burst community for continuous observation through advanced radio telescopes
ALMA, VLA, CHIME, UTMOST with a hope that detection of unseen FRBs at low latitudes unveil the secrets of the Universe.
Solid lipid nanoparticles were prepared by using the solvent evaporation method. The prepared solid lipid nanoparticles of
felodipine from different batches were weighed accurately and filled into appropriate-sized capsules for further evaluation.
The prepared nanoformulation was tested in vitro for drug entrapment efficiency found to be 97-99% for the formulation
with soya lecithin and glyceryl mono-stearate and percentage yield. The results of the in vitro drug release study for all
formulations performed at gastric pH 1.2 indicated that the drug was released in an immediate manner within 60 minutes,
which could be due to a burst effect or a faster rate of drug release due to smaller particle size SLN13 the concentration of
Glycerol Monosterate- 576.522mg and Poloxamer 188. In vitro release data from standardised nanoformulations was fitted
to various release kinetics models for the drug release mechanism. The optimised formulation demonstrated improved drug
release and entrapment efficiency, and in vitro release data were fitted to various kinetic models to better understand the
drug release mechanism. In vitro assay results were ranged between 76.5 to 96%, Zeta potential -40.75 ± 2.33 (mV) ± SD,
entrapment efficiency 99.32. Accelerated stability studies for standardised nanoformulations were performed for 6 months in
accordance with standard ICH guidelines, and no appreciable changes in the physical appearance, drug content, and in vitro
drug release rates of the nanoformulations were observed. As a result of the study's evidence, it is concluded that felodipineloaded solid lipid nanoparticles are the best choice for hypertension.
This study aimed to understand the behavior of the carbonate system in the Cananéia-Iguape Estuarine-Lagoon Complex
(CIELC) to evaluate its potential as a source or sink for atmospheric CO2. This estuarine-lagoon complex is one of the most
extensive in Brazil, more than 100 km long and covers protected and sparsely inhabited regions of the state of São Paulo. This
system presents, in its southern portion, most preserved areas, and evident anthropogenic impact in the northern portion,
where an artificial canal was created in the second half of the 19th century, with the aim of shortening the navigation path link
the river to the estuarine system offering a passage to the sea, resulting in several modifications, both from a hydrodynamic
and biogeochemical mechanisms. Sampling of salinity (S), temperature (T), total alkalinity (TA), pH, dissolved oxygen (DO),
and nutrients (P and Si) were performed along the CIELC in the winter of 2012 and in the summer of 2013. S, TA, pH and
nutrients were used to support the understanding the behavior of the species in the carbonate system (CO2
, HCO3
-
, CO3
2-)
and related variables were used to calculating the partial pressure of CO2
(pCO2
). The data showed the difference in salinity
and carbonate members distinguished the northern and southern areas, the influence of the marine waters entrance by the
bars, and the predominance of the system as a source of CO2
, even in the most preserved area. However, the difference in this
behavior is most evident under anthropogenic pression offering risk of extreme changes in direction to the southern sector,
now observed until the intermediate point of the system. The recommendation is an urgency in monitoring this region to

Church’s Sideband (Monadenia churchi) is a medium-sized endemic terrestrial snail with a broad geographic distribution. It
provides an excellent opportunity to evaluate habitat variance across a diverse geologic, topographic, and ecologic landscape.
Herein I document and model variance in macrohabitat characteristics of five riverine-segregated Eco-geographic Units (populations) within the range of the species (Mad and Sacramento rivers, and Northern, South-Central, and Western basins).
The most common forest cover-types were Sierra Mixed Conifer (49.6%), Douglas Fir (14.1%), and Montane Hardwoodconifer (8.7%). Statistical comparisons showed significant differences in 93.3% of the cover-types among groups. Principal
Components Analysis of macroscale biotic and abiotic ecological variables accounted for 51.7% of the combined variance along
both vectors for the species. K-means clustering using Multidimensional Scaling showed good separation of point-samples for
the Sacramento River and Western Basin, but there was considerable overlap in point-samples among the remaining groups.
All Habitat Suitability Models showed suitable habitat widely distributed throughout the range of M. churchi, but most areas consisted of Low suitability interspersed with few areas of Moderate to High “quality” habitat. For all groups, Generalized
Additive Model regression of grid-cell density against macroclimatic co-variates exhibited the best fit compared to models
of Forest Structure and Exposure-Distance to Nearest Stream. Dot-plots of variable importance, produced by Random Forest
Regression, showed that predictor categories with importance values > 10 were: 1) Macroscale Climate (64.0%, n = 78), followed by Exposure-Distance to Nearest Stream (20.0%), and Forest Stand Structure (16.0%).
As the importance of promoting college student mental health increases and campuses work to prevent suicide, resident assistants (RAs) are called upon to serve as gatekeepers to facilitate professional help as a part of suicide prevention initiatives on campuses. However, assessing the efficacy of suicide prevention training is lacking. This study develops and validates the Gatekeepers Self-Efficacy Scale among resident assistants (RAs) based on the Question, Persuade, Response suicide prevention model. Exploratory Factor Analysis (EFA), Parallel Analysis, and Multidimensional Graded Response model (MGRM) were used with 302 RAs sample. Two factors were found, (1) Communicating about Crisis and (2) Knowledge of Resources, with appropriate item fit and parameter estimates. The response patterns of the two factors and their correlations with objective suicide prevention knowledge were estimated and discussed. The implications of these findings for practical application are discussed, along with suggestions for future studies.
Climate change is one of the primary factors contributing to the loss of biodiversity worldwide. The purpose of this review paper was to give serious thought about the present and future impacts of climate change on biodiversity, even though we are not aware of its synergistic effects on biological populations. In order to fully understand the biota's reactions to these climatic
changes, we also concentrated on how these changes impact their phenology and physiology. This review article's subjects are
covered in a non-random order to make it easier for readers to understand the connections between biodiversity and climate
change. We also discussed about how 1.1°C of global warming brought about by human activity has altered the Earth's climate
in ways never seen before and negatively impacted human health. We covered how to safeguard our biota by implementing practical conservation strategies at the end of this review article in order to reduce the effects of climate change on it. We hope that one day, because research on climate change and biodiversity protection is interdisciplinary and spans many different scientific areas, we will be able to address all these concerns and preserve our biota from their terrible consequences.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

Abstract
All astronomical bodies originate inside clouds of gas and dust, therefore there should be a common process that leads to
their condensation. In a galactic cloud there is always a gradient of speeds from point to point. Thanks to it, vortices originate
that rake the material of the surrounding cloud gradually forming large gaseous disks, inside which vortices of second order
develop that concentrate the matter of their orbits forming smaller and much denser disks, within which third order vortices
further concentrate the matter. The dense cores of these vortices finally condense in massive bodies: sun, planets and satellites.
The result should be a well ordered planetary system with no “debris” around and where both planets and satellites obey to
a precise rule of the distances from their central body. The solar system complies with these conditions with three main
exceptions. First, in an orbit where a large planet should be there is only a huge number of scattered asteroids. Second, Earth
and its moon with all evidence were not formed in the same vortex, which means that Moon originated somewhere else. Third,
Neptune’s satellite system has been shattered by the intrusion of a foreign body, Triton, and its largest satellites are missing.
These exceptions seem to be strictly connected to each other and all due to a unique event, that is: Triton has diverted the
largest Neptune satellite towards the Sun. This satellite impacted at high speed against the missing planet, scattering myriads
of fragments from its mantle and pushing it towards the sun, where it eventually fell. The planet had at least 4 satellites some
of which remained in their previous orbit, but two of them were dragged towards the sun and were captured by Earth. The
largest became its lonely moon while the second fell on its surface giving origin to the continents. This event happened about
3,96 billion of years ago, as it is proven by the ages of the numerous samples brought from the moon.

Introduction
The current theory about the origin of our moon
maintains that it was formed by material removed from
Earth by a catastrophic impact with a foreign body. Not a
very convincing hypothesis because, among other things,
it assumes that our satellite was born as a result of an
extraordinary and unrepeatable event not applicable to
other similar satellites of the solar system [1].
No more convincing are the theories about the origin of
the other satellites and even less those about the formation
of the planets and the stars [2-4]. For each of them, in fact,
different explanations are provided, which seems unlikely.
All astronomical bodies, in the end, originate from clouds of
gas and dust. The process that leads to their condensation
within these clouds should be the same regardless of their
size.
