Published: February 2023

This paper proposes image processing algorithms to recognize Three types of blood cells in Origenism body. First one is RBC , Second one is WBC and third one is Platelets. Theas are three types of blood cells have a very important role on human body for transport of Gases, Body immunity and Blood clotting. On a human body the blood have a great importance of a life. The Blood provide a surface for gases exchange on lungs and cellular region. This gases are helpful for cellular respiration and produesed cellular energy like ATP(ATP is a energy coin of a cell ). This energy are use in cellular activities and cellular repairing. Blood is a viscous fluid formed of cellular element suspended in plasma. The cellular composed of: Erythrocytes(R.B.C.), Leucocytes(W.B.C.) and Platelets. Plasma is a viscous, translucent, yellowish fluid composed of water (90%), protein (7%),organic salts(1%), and organic compound (2%) such as amino acids, lipids, and vitamins. The total blood volume is about 5L (depending on body size). Outside the blood vessels, blood undergoes a complex rection called coagulation or clot formation, which plays an importance role in repairing damaged blood vessels and preventing blood loss. The ability to provide all types of ancillary studies necessary to make specific diagnosis that will dictate treatment protocols will be demonstrated. A brief description of the general rule of circulation differentiating benign from malignant will be presented. It is hoped that this review will benefit all practicing clinicians that may face certain diagnostic challenges requiring the use of blood material. In the human embryo, the first site of blood formation is the yolk sac. Later in embryonic life, the liver becomes the most important red blood cell-forming organ, but it is soon succeeded by the bone marrow, which in adult life is the only source of both red blood cells and the granulocytes. Both the red and white blood cells arise through a series of complex, gradual, and successive transformations from primitive stem cells, which have the ability to form any of the precursors of a blood cell. Precursor cells are stem cells that have developed to the stage where they are committed to forming a particular kind of new blood cell. In a normal adult the red cells of about half a litre (almost one pint) of blood are produced by the bone marrow every week.

Published: February 2023

Cascaded H-bridge multilevel inverters have been developed for applications including user interface of renewable energy, voltage regulation, VAR compensation, and harmonic filtering in power systems. A modified cascaded H-bridge multilevel inverter (MLI) is implemented for solar applications. Multilevel inverter based on cascaded H-bridge topology will help in the reduction in number of switches. This concept helps to reduce the complexity of switching compared to other multilevel inverters. In this paper, cascaded H-bridge multilevel inverters output is validated with a combination of RLC load. With the increase of the levels of inverter the total harmonic distortion will be reduced.

It can be said that in the new education policy, where opportunities have been provided to the students and institutions, on the other hand, many challenges will also be present in front of them like a huge mountain.
A Study on Plant Structure
Authors: - Anil Kumar Saini , - Vishnu Kumar Jatav , - Amit Kumar Mishra , - Khemchand Bairwa
Published: February 2023

This paper propose image processing algorithms to recognize The Plant structure in Plant Kingdom. Anatomy is one of the oldest disciplines of plant science, and there is a huge amount of accumulated knowledge. At the same time, anatomy is highly important as a linking medium between several key branches of modern plant science. Detailed anatomical studies, these days using X-ray microtomography, allow much more detailed understanding of plant fossils and thus facilitate the accumulation of greatly extended non-molecular data sets. The use of anatomy is one of most efficient ways of increasing the number of characters in data sets employed to link fossil and extant plants. This link is essential for achieving the ambitious goal of acquiring a holistic knowledge of plant evolution combining the direct, but fragmentary evidence from the fossil record and the indirect, though highly informative data of molecular phylogenetics and phylogenomics. Anatomy is one of key tools of evo-devo research. Indeed, analyses of gene expression patterns are performed using anatomical techniques. More importantly, developmental biology of plants explores functioning of plant meristems and aspects of cell and tissue differentiation, the topics that have a long history of research in the framework of plant anatomy. Anatomy provides detailed information of the developmental processes in extant and extinct plants. Obviously, the detailed knowledge assembled through centuries of anatomical research has great perspectives of use in evolutionary developmental biology. Many theories developed in plant anatomy can be tested using molecular tools (e.g. Povilus et al., 2020), but it is important to pose the questions. Anatomy has many implications for plant physiology and ecology and provides an excellent tool for investigating historical aspects of these disciplines, including those related to climate change.

Authors: - Dharm Veer Singh
Published: February 2023

The Role of Autobiography in the review of M.K. Gandhi, J.L. Nehru and N.C. Choudhary. Autobiography is a proper medium of self expression, which is an innate human faculty. It is literature of personal revelation and its main interest lies in conscious or unconscious. Self- revelation or self portrayal by the author. M.K. Gandhi, J.L. Nehru and N.C. Chaudhary are incontrovertibly three significant Indian English autobiography writers. The Role of autobiographies of three significant writers belonging to three different, in fact, diametrically opposed back grounds will, no doubt be as delightful as profitable. They belonged to the freedom struggle of India and had an ambition to make the country independent. They belonged to political arena of India during British Rule, but Gandhi was not fully. As a writer they practised the same genre, they sharply differ from each other in manner of presentation and focus.
Causes and Impact of Agricultural Labour Migration: A Case Study of Ranchi District
Authors: - TARA BHAGAT , - GOPAL CHANDRA SINGH
Published: February 2023

India's economy has always been based on agriculture. The key component in the production of agriculture is laborers in the agricultural sector. The use of human resources is crucial. Due to agricultural workers moving to different regions of the nation to find work, there is an imbalance in the supply and demand for labor. Labor migration is still a significant issue that needs to be tackled in order to stabilize output in a certain area. The rate of labor absorption in agriculture may rise under certain conditions if cultivation is intensified. Migration is, and has been for millennia, a way of life for many poor people all throughout the world. However, globalization has drastically changed the scope of migration because it has made it easier for people to travel and made them more aware of opportunities elsewhere. In Jharkhand and India, seasonal agricultural laborer migration is not a recent phenomenon. During their rule, the British mobilized the labor force for commercial crop cultivation, mining, and other administrative objectives. The socialist-capitalist (mixed economy) model of development was implemented by the Government of India (GOI) through five-year planning after the country's independence. The regional gap is growing as a result of the inadequate agricultural development policies, which is fueling a rise in the seasonal migration of agricultural laborers. The goal of inclusive growth strategy is to integrate underrepresented groups into the mainstream economy, including women, marginalized groups, castes, classes, and tribes.

The Implications of the Performing Arts in Higher Education in India: An Analytical Study
Authors: - Bilambita Banisudha
Published: February 2023

Performing arts let youngsters explore their emotions and broaden their imagination, while also allowing them to discover and express their distinctive voices. A student's brain, body, and emotions are all stimulated in different ways by the many forms of music, dance, and theatre that they participate in. Performing arts can help students develop their cognitive abilities. As a result, arts education has a significant role to play in preparing students in higher education for a wide range of future vocations. When it comes to music or theatre, the creative process is well-rounded and allows students to focus on a particular issue and share their work with a big group of people. Students who are naturally timid learn how to deal with social situations, whereas anxious students may find refuge in the arts. As a result, students build self-confidence in presenting their work to a larger audience since they are forced to step outside of their comfort zones. The University seeks to produce graduates who can communicate effectively, think critically, study freely and cooperatively, and demonstrate expertise in their chosen fields. Performing arts instruction is a crucial factor in the development of communication skills. The goal of this paper is to determine the extent to which performing arts influence a student’s cognitive abilities and create an environment in which they can meet their physical, social, cultural, spiritual, and other personal needs while also developing a strong sense of a social and civic obligation for leadership and the service in dynamic, a multicultural society.

Gomti River is the lifeline for Lucknow and is a major source of water for domestic use. Over the years extensive urbanization in Lucknow city has changed the characteristics of Gomti River due to disposal of untreated wastes, which mainly include sewage, solid sludge and hospital wastes. This has caused the degradation of Gomti River resulting in aquatic pollution. The river water is extensively used for washing, bathing, recreational and religious activities. In the present paper we are presenting the findings pertaining to different physico-chemical and microbiological parameters, which have been assessed to determine the impact of socio-biological activities on the quality of river water. For this sampling of water has been done from six different sites at three points of every site, in the month of June, 2006 from Gomti River. Hardness of water samples ranged from 315.00-643.00 mg/l. the pH values of water ranged from 8.60- 8.90. The total dissolved solids varied from 230.40-530.50 mg/l and the dissolved oxygen of water varied between 0.00-4.80 mg/l. The chloride concentration varied between 99.30- 224.30 mg/l and the alkalinity of water samples ranged between 307.70-480.00 mg/l, the nitrate of water samples varied from 11.8- 18.6 mg/l. The fluoride concentration water sample was 0.58- 1.15 mg/l. The bacteriological examination of water yielded the results that >1600/100 ml of coliform 1600-> 1600/ 100 ml of fecal coliform were present in the water samples. These results have been clearly shown that the water of Gomti River is severely affected by various socio-biological activities around sampling site.

Published: February 2023

Let $N=\binom{n}{2}$ and $s\geq 2$. Let $e_{i,j},\,i=1,2,\ldots,N,\,j=1,2,\ldots,s$ be $s$ independent permutations of the edges $E(K_n)$ of the complete graph $K_n$. A MultiTree is a set $I\subseteq [N]$ such that the edge sets $E_{I,j}$ induce spanning trees for $j=1,2,\ldots,s$. In this paper we study the following question: what is the smallest $m=m(n)$ such that w.h.p. $[m]$ contains a MultiTree. We prove a hitting time result for $s=2$ and an $O(n\log n)$ bound for $s\geq 3$.
Cooperative Colorings of Forests
Authors: Bradshaw Peter
Published: February 2023

Given a family $\mathcal G$ of graphs spanning a common vertex set $V$, a cooperative coloring of $\mathcal G$ is a collection of one independent set from each graph $G \in \mathcal G$ such that the union of these independent sets equals $V$. We prove that for large $d$, there exists a family $\mathcal G$ of $(1+o(1)) \frac{\log d}{\log \log d}$ forests of maximum degree $d$ that admits no cooperative coloring, which significantly improves a result of Aharoni, Berger, Chudnovsky, Havet, and Jiang (Electronic Journal of Combinatorics, 2020). Our family $\mathcal G$ consists entirely of star forests, and we show that this value for $|\mathcal G|$ is asymptotically best possible in the case that $\mathcal G$ is a family of star forests.

Mathematical Model and Simulation for Improving Brake, Bump and Roll Steers in Light Commercial Vehicle (LCV)
Authors: Mahadevan Pichandi  , Satish Kumar R
Published: February 2023

Due to recent infrastructural developments and emerging competitive automotive market in India, there is seen a huge shift in customer demand and vehicle drivability pattern for small commercial vehicles. Various factors contributing to driver’s fatigue include driver negligence, inappropriate driving habits and vehicle inherent design error due to which a driver is forced to make frequent steering wheel corrections so as to make the vehicle run in a straight line. Thus, optimization of steering, suspension and front axle geometry becomes important for improving the overall vehicle drivability and reducing the driver fatigue. Mentioned herewith are the major kinematic characteristics in a vehicle which plays vital role for ensuring vehicle improved drivability – Brake steer, Bump steer, Roll steer and Ackerman Geometry. As on today, the above analysis for deriving optimized linkages hard points for steering, suspension and front axle system are done in customized Multi body dynamics software’s like ADAMS/Trucksim. Although the derived hard points in such MBD software’s are precise yet there are several drawbacks in such approach like increase in overall project time plan, mainly due to the vehicle packaging issues for the proposed hard points and also these software customized license and AMC are quite high which increases the overall operating cost of a project. In this paper, an approach has been developed so as to derive these linkages hard points through mathematical calculation and kinematic simulation model in product design Catia platform itself. This helps the designer to derive the optimized hard points of linkages for “n” number of design iterations at the concept stage itself. Thus, this design methodology saves not only on the project design cost but also it reduces the overall product design lifecycle and gives the respective designer to choose the optimum hard point based upon the vehicle packaging feasibility Brake steer, Bump steer, Roll steer, Catia 2D layout, Camber, TCD, Ackermann error.
Investigation and Study of Ammonium Hydroxide and Biodiesel Blend as an IC Engine Fuel
Authors: Bokam Surya Sashikanth  , Ch. Sainath Reddy  , Ravi K
Published: February 2023

The use of conventional fossil fuel has resulted in global warming. Biodiesel is a substitute fuel obtained from vegetable oil by transesterification process which can replace conventional diesel. Good alternative to traditional hydrocarbon-based fuel is ammonia combined with a biofuel. Ammonia is free of Carbon and can be extracted from sustainable renewable energy sources. It can be used with slight modifications on current IC engines. However running the engine on pure ammonia poses a lot of challenges which needs to be tackled. Running the engine on Biodiesel results in slightly more NOx emission, compared with traditional fuel. In the present study an experimentation has been carried out to examine the effect of biodiesel and ammonium hydroxide blend on ICE performance, emission and combustion aspects, in terms of specific fuel consumption, brake thermal efficiency, Nitrogen oxides (NOx) and Hydrocarbon (HC), Carbon monoxide (CO) and Carbon dioxide emissions. Biodiesel blends are examined using a single cylinder four stroke Kirloskar ICE. Experiments have been performed with varying percentages of ammonium hydroxide (3%, 6%, 9%) and B50 (50% diesel and 50% Karanja biodiesel) blended with Diesel and then compared with base line conventional diesel. This paper will help in understanding how percentage variation in ammonium hydroxide and biodiesel blend will effect emission and performance.

Neighborhood, Topography, and Wind Direction Effects on Wind Pressure Distribution on the Low-rise Building Roof
Authors: Camilo Vitor G. O. , De Campos Marco D.
Published: February 2023

Low-rise buildings are the majority of the houses that are constructed all over the world. Experiments of the wind loads acting on these buildings provide vital information to design secure structures and adverse weather conditions resistants, considering the basic parameters as roof slopes and the wind direction. This study estimated the distribution of wind pressures around the contour of buildings with gable roofs, considering diverse neighborhood conditions, namely the number and geometric configuration of buildings on the ground, in conjunction with the different angles of wind incidence and topography. The simulations took place with Ansys Workbench software, and the RNG K-Epsilon turbulence model and tetrahedral mesh were employed. The application validation of the CFD technique occurred in the double-sloped pitched roof structure. The results showed good concordance with the literature. The pressure coefficients were analyzed, as well, in the flow visualization, highlighting the attachment points and the recirculation zones.
Numerical Simulation of the Elastic Behavior of the Automotive Brake Disc in Dry Sliding Contact With the Pads
Authors: Kerrouz S. , Tamine T. , Bouchetara M.
Published: February 2023

During braking and when the disk brought into contact with the brake pads which represent the friction body, mechanical stresses are imposed at the contact zone. All physical parameters (temperature, pressure speed and mechanical characteristics, and tribological conditions change over time), heat from friction generated at the interface, and temperature may exceed the critical value. All these problems that allowed us to do this study which concerns the numerical simulation by finite elements of a mechanical torque in dry sliding contact with motor vehicle disk/brake pads at the moment of stop braking using the ANSYS calculation code 14.5 which is based on the finite element method with its friction contact management algorithms. This behavior was analyzed in the transient case in terms of equivalent stresses and deformations (Von Mises) as a function of the braking conditions ( the type of loading, the speed of rotation of a disk, the pressure force applied to the brake pads, the coefficient of friction between the disk and the pads), and the thermal conditions (the temperature of the disk, and the heat flux in the disk, and the heat exchange by convection over the entire surface of the disk), the geometrical characteristics of the disk pads assembly and the position of the pads with respect to the brake disk and the mechanical parameters assembly and the position of the pads with respect to the brake disk and the mechanical parameters ( Young’s modulus, density, Poisson coefficient). This analysis allows us to see the behavior of the disk and the pads in contact and to recognize these damages in order to find the optimal technological solutions that will meet the needs of the engineer responsible for the design of the braking system, in particular the disk-pads torque, and to improve this system and make it more reliable and for an optimal and economical choice of the disk and pads well resist heat.
Examining level of school garden integration among Georgia elementary agricultural education teachers
Authors: Frederickson Jade , Peake Jason
Published: February 2023

This study used the GREEN (Garden Resources, Education, and Environment Nexus) tool to examine the level of school garden integration in elementary agricultural teachers’ classrooms. The tool describes the 19 necessary components (e,g., organizational support, garden space) for gardens to become integrated within the school. This study utilized mixed methods with a concurrent triangulation design based on quantitative data obtained from an online questionnaire and qualitative data collected from focus groups. The findings were used to validate the findings produced by the other method. The population consisted of elementary agriculture teachers in Georgia. Though a definitive model does not yet exist for elementary agriculture education, it was clear that teachers rely on hands-on, experiential teaching activities such as garden maintenance tasks and taste tests. Teachers struggle most with volunteer and parent involvement and social events in the garden, largely because of the lasting impacts of the COVID-19 pandemic. Future research should consider how the results of the GREEN tool can shape professional development topics and help teachers set goals to improve their garden’s level of integration. Research should also examine how COVID-19 impacted school garden programs.

So schaffen Unternehmen Nachhaltigkeit
Authors: Reger Hendrik
Published: February 2023

Nicht zuletzt Bewegungen wie „Fridays for Future“ ist es zu verdanken, dass sich unser Bewusstsein für den Umweltschutz geschärft hat. Auch an der Logistik ging dieser Trend nicht spurlos vorüber. Durch die stetig wachsende Globalisierung fühlen sich mehr und mehr Unternehmen in der Verantwortung, ihren ökologischen Fußabdruck immer im Blick zu haben. So verwundert es nicht, dass sich viele eine „grüne Logistik“ auf die Fahne schreiben. Ziel einer solchen nachhaltigen Firmenpolitik ist es, Betriebskosten zu senken, Gewinne zu steigern und gleichzeitig negative Umweltauswirkungen weitestgehend zu vermeiden. Vor diesem Hintergrund sind die richtigen Softwarelösungen, die Prozesse digitalisieren und weitestgehend automatisieren, ein wichtiger Baustein hin zur grünen Logistik.
