Centrifugal pumps work by using an impeller to increase the pressure and flow of a liquid. Liquid enters the center of the impeller and is accelerated outward by the curved blades of the impeller. This increases the pressure and flow of the liquid. Calculating the required head of a centrifugal pump involves accounting for static head, pipe friction losses, and adding additional head for safety. Proper pump selection is based on matching the required head and flow rate to the pump performance curves. Cavitation and ensuring adequate Net Positive Suction Head (NPSH) are also important considerations for centrifugal pump operation.

Evaluation of Protective Efficacy of Hydro Alcoholic Extract and Methanol Fra...paperpublications3
Abstract: The objective of the study was to investigate and compare the radioprotective effect of hydroalcoholic extract (HAE) and methanol fraction (MF) of Tamarindus indica pod in mice against electron beam radiation. Animals were treated with 100 mg/Kg body weight of HAE and MF of T. indica for 15 consecutive days before exposing to 6Gy (sublethal dose) whole body EBR. The irradiation of animals resulted in an elevation in lipid peroxidation and reduction in glutathione, total antioxidants and antioxidant enzymes such as superoxide dismutase, glutathione peroxidase and catalase activities. Irradiated group had shown micronucleus in the bone marrow cells. Treatment of mice with HAE and MF before irradiation, reduced the symptoms of radiation sickness when compared with the irradiated group. Pretreated mice showed a significant reduction in lipid peroxidation followed by elevation in reduced glutathione, total antioxidants and antioxidant enzymes such as superoxide dismutase, glutathione peroxidase and catalase. It also showed a reduction in the micronucleus formation in bone marrow cells. The findings of our study indicate the protective efficacy of HAE and MF on radiation induced biochemical and chromosomal changes in mice may be due to its free radical scavenging and increased antioxidant levels. It also reveals MF, a better protective agent than that of HAE of T. indica.
Abstract: Water is crucial factor in our life. It is one of fundamental needs of human being. As far as our health is concerned the water should be fit for drinking, it should not contain any undesirable substances rendering it unfit for drinking and domestic use. For such water we have to depend on sources of water such as river, lake , well etc. but to make it upto the standards of drinking water it should be treated1. In big cities municipal corporation supplies water to the people after treating it in treatment plant. In pimpri & chinchwad city PCMC treats and supplies water to city. Corporation divided city in 46 sectors to distribute water. Samples were collected from each of these sectors and conducted various tests such as hardness test, chloride content test, etc. To examine the contamination of water at tap sources.

This study has been done to know the use of electronic health records among nurses in private medium sized hospitals of Tamil Nadu, India. The objective of the study is to explore the use of Electronic Health Records and barriers in using it among nurses. This study also analyzes the factors affecting nurses to adopt electronic health record. Only a third of the nurses (33%) use electronic health record. Lack of training is the major hindrance in use electronic health record among nurses.
Abstract: This paper explores the socio-economic situation of women in Lesotho. Based on secondary data obtained from Bureau of Statistics, Land Administration Authority, country analytical annual reports ministerial reports as well as Lesotho government website; it analyzes the status of Basotho women with regard to access and control over economic opportunities. Main indicators discussed include access and control of resources like in education and land ownership, participation in decision making e.g. political participation. The issue of women and discriminatory laws is also addressed. This study is restricted to the relevant and available data and information on access on August 2015. The statistical data in this paper suggest that female is a dominating gender as far as land ownership is concerned. With regard to economic decision making and political participation, there is gender imbalance with men as a dominating gender. Women have been victims of discriminatory laws which denied them opportunity to own or inherit land and immovable property and hold senior positions in companies. These laws were later amended although gaps still exists. The finding shows that Lesotho has relatively high literacy and net primary school enrolment, but with a reversed gender gap signifying discrepancy to the advantage of girls. Gender related policies should be formulated and implemented so as to increase women’s representation and inclusiveness in political participation and economic decision-making. Given the responsibilities of women, improvement of women’s socio economic status in all sectors will not only be of essence to women alone, but also families and communities as well. This will also enhance women empowerment and contribute to inclusive sustainable economic growth, reduce poverty and social injustices and other forms of inequalities.Measures need to be developed to improve access to education for boys so as to ensure a balanced human development outcome. Amendments on Laws of Lerotholi should be a well understood public knowledge.
Evolution Analysis of Structures And Landforms Of Thalisain Area, Garhwal Him...paperpublications3
Abstract: Evolution of landforms of any basin is due to its diversity in lithology, geological structures and their impact on drainage pattern. Thalisan area is combination of two basin (partially) Western and Eastern Nayar and Bino, the area has a distinctive landform-ecology. The landforms are severely deteriorated by geo catastrophic processes like landslide, rockfall, soil creep and debris flow. Impact of morphological characters on the terrain is reflected by drainagebasin of the area. The repetitive calculated values of all the morphometric parameters of different litho-tectonic zones were processed. The quantitative study of these morphometric parameters suggests that the basin shape, stream density, relief, ruggedness, stream frequency and circularity index are controlled by altitude and climateas well as nature of bed rocks. The morphometric parameters like absolute relief, relative relief, dissection index, drainage texture, drainage frequency and slope were analysised and superimposed to workout homogeneity in landforms units.
Barriers to Development and Progress of Entreprenurs: Case of Lesothopaperpublications3
Abstract: This paper gives an analysis on the barriers to development and progress of entrepreneurs in Lesotho. It adopts the use of primary data which was collected through personal interview with structured questionnaire and direct observations. The results reveal that all entrepreneurs regardless of gender are equally faced with economic barriers which comprise lack of finance and problems of markets. Furthermore, the socio-cultural factors which involve negative view of society towards women and individual familial factors especially family problems basically affect women; these could be attributed to the fact that women are liable for domestic responsibilities in their families. However, structural barriers are observed to have an insignificant impact on development and progress of Lesotho entrepreneurs. Following these findings, through trade organizations, the government could assist in supporting the establishment of mentoring networks facilitating the development of the emerging entrepreneurs, as well as providing training workshops on women empowerment. Also, mechanisms to support entrepreneurs and assist them in gaining access to international markets should be developed.

Both units were planted with Schoenoplectus grossus (Giant bulrush).After establishing plants for three months, the treatment unit was saturated with seven Biochemical Oxygen Demand (BOD) loads of diluted and neutralized dairy wastewater ranging from 5g/m2d , 16g/m2d, 20g/m2d, 24g/m2d,33g/m2d, 48g/m2d and 186 g/m2d. Seven days were maintained as effective retention time under each BOD load. Control unit was maintained without the addition of dairy wastewater. Samples were collected from the inlets and outlets of each unit and analyzed for BOD, Chemical Oxygen Demand (COD),Total Nitrogen (TN) and Total Phosphorous (TP).Removal efficiencies of BOD, COD, TN and TP were calculated. The results of this study showed BOD removal efficiencies in the range of 30%-100%, COD removal efficiencies in the range of 75%-92%, TN removal efficiencies in the range of 40%-100% and for TP in the range of 0%-100% with respect to studied loading rates. Based on these results this paper suggests that this type of pilot scale SSHF CWs planted with Scheonoplectus grossus is appropriate for removal of BOD, COD, TN and TP in dairy wastewater arising from small and medium sector dairy industries.

Problems and Prospects of SMES Loan Management: Case of Lesothopaperpublications3
Abstract: Small and medium enterprises play a fundamental role in economic growth and developments. The economies of all market-oriented nations depend on the efficient operation of complex and delicately balanced indispensable element in these systems - systems of money and credit However, historically SMEs financing remains as major challenge to the growth of SME. This paper therefore tries to identify some underlying problems from the banks perspective. This study is based on primary data which is collected through personal interview with structured questionnaire and direct observations. Findings indicate that banks appear to be facing serious challenges of high cost of gathering information and collateral. Both high costs to gather reliable information on SMEs and high administration costs on loans made to SMEs were found to have fundamental impact on SME lending. Though lack of finance appears to be a major challenge hindering SMEs growth, this hindrance may be mostly enhanced by constraints that are within SMEs themselves.

Microalgae as Potential Feedstock for Biodiesel Production-A Reviewpaperpublications3
Abstract: This paper provides a background on the usage of microalgae which are increasingly recognized as promising for biofuel production. Compared to terrestrial crops, microalgae are very biodiverse and offer considerable versatility for a range of biotechnological applications including; the production of animal feeds, fuels, high value products and waste-water treatment. Microalgae are used as nutraceuticals and pharmaceuticals, as well as other industrial applications. In terms of environmental biotechnology, they are useful for bioremediation of agro-industrial wastewater, and as a biological tool for assessment and monitoring of environmental toxicants such as heavy metals, pesticides and pharmaceuticals. Microalgae are being considered as a viable feedstock for large-scale production of biodiesel. However, it may look simpler to obtain lipids from microalgae, the overall process of choosing an algal strain, cultivation, harvesting, dewatering, and extraction of oil is quite complicated and may not be economical at present.

Study of Bio-Nano Composite of Poly-Lactic Acid for Food Packaging- A Reviewpaperpublications3
Abstract: The impact of environment, economic and safety challenges have provoked the need to partially substitute petrochemical based polymer with bio degradable ones. [Poly lactic acid] PLA is the leading biodegradable polymer but its applications are limited by its relatively high cost, poor impact strength and barrier properties, which may be improved by adding reinforcing compounds (fillers), forming composites. Most reinforced materials present poor matrix–filler interactions, which tend to improve with decreasing filler dimensions. The use of fillers with at least one nanoscale dimension (nanoparticles) produces nanocomposites. Nanoparticles have proportionally larger surface area than their microscale counterparts, which favors the filler–matrix interactions and the performance of the resulting material.
Applications of nanomaterials in combination with PLA structures for creating new PLA nanocomposite with greater abilities are also covered. These approaches may modify PLA weakness for some food packaging applications. Nanotechnology approaches are being broadened in food science, especially in packaging material science with high performance and low concentrations and prices, so this category of nano-research is estimated to be revolutionary in food packaging science in the near future. The linkage of the 100% bio originated material and nanomaterial opens new windows for becoming independent, primarily, of petrochemical based polymers and, secondarily, for answering environmental and health concerns will undoubtedly be growing with time.
This study seeks to overcome PLA limitations by reinforcing PLA with nanoparticles and low-cost agricultural residues. The work presented in this thesis focuses on exploration of following relevant aspects:
• Preparation of PLA nanocomposite from LA [lactic acid].
• Reinforcement of various fillers during preparation.
• Testing of the formed nanomaterial to study the enhanced properties for sustainable green food packaging.
• Comparative study of the newly formed nanocomposites with respect to its properties
Nanotechnology has demonstrated a great potential to provide important changes in food packaging sector.
Nanocomposites are promising to expand the use of bio-degradable polymer, since the addition of nanoreinforcement has been related to improvement in overall performance of biopolymers, making them more competitive in a market dominated by non-biodegradable materials.

Implementation of T-Junction Traffic Light Control System Using Simatic S7-20...IJERA Editor
A conventional traffic light control system is designed by using devices such as timers, relays and
contactors etc. The critical timing operation is required to be carried out under the existence of heavy
traffic situations. This conventional practice leads to many problems that need additional maintenance
cost and subsequent delay for a long time. With the help of a PLC, the requirement of fast automation
and effective optimization of traffic light control system can be achieved. Use of PLC helps us to
develop this process not only for traffic signal on the roads, but also on the movement of trains and
the transfer of containers in ports in maritime works. In order to provide a solution to the above
problem, this paper introduces an execution and implementation of T-junction traffic control system
using SEIMENS S7-200 PLC. Programming in PLC is written in ladder logic with the help of STEP7

Speed Control of Induction Motor Using PLC and SCADA SystemIJERA Editor
Automation or automatic control is the use of various control systems for operating equipment such as
machinery, processes in factories, boilers and heat-treating ovens, switching in telephone networks, steering and
stabilization of ships, aircraft and other applications with minimal or reduced human intervention. Some
processes have been completely automated. The motor speed is controlled via the driver as an open loop control.
To make a more precise closed loop control of motor speed we will use a tachometer to measure the speed and
feed it back to the PLC, which compares to the desired value and take a control action, then the signal is
transferred to the motor – via driver – to increase / decrease the speed. We will measure the speed of the motor
using an incremental rotary encoder by adjusting parameters (PLC, driver) and also we need to reduce the
overall cost of the system. Our control system will be held using the available Siemens PLC. In addition, we will
monitor motor parameters via SCADA system.

Measuring gravitational attraction with a lattice atom interferometerSérgio Sacani
Despite being the dominant force of nature on large scales, gravity remains relatively
elusive to precision laboratory experiments. Atom interferometers are powerful tools
for investigating, for example, Earth’s gravity1
, the gravitational constant2
, deviations
from Newtonian gravity3–6
and general relativity7
. However, using atoms in free fall
limits measurement time to a few seconds8
, and much less when measuring
interactions with a small source mass2,5,6,9
. Recently, interferometers with atoms
suspended for 70 s in an optical-lattice mode fltered by an optical cavity have been
demonstrated10–14. However, the optical lattice must balance Earth’s gravity by
applying forces that are a billionfold stronger than the putative signals, so even tiny
imperfections may generate complex systematic efects. Thus, lattice interferometers
have yet to be used for precision tests of gravity. Here we optimize the gravitational
sensitivity of a lattice interferometer and use a system of signal inversions to suppress
and quantify systematic efects. We measure the attraction of a miniature source mass
to be amass = 33.3 ± 5.6stat ± 2.7syst nm s−2, consistent with Newtonian gravity, ruling out
‘screened ffth force’ theories3,15,16 over their natural parameter space. The overall
accuracy of 6.2 nm s−2 surpasses by more than a factor of four the best similar
measurements with atoms in free fall5,6
. Improved atom cooling and tilt-noise
suppression may further increase sensitivity for investigating forces at sub-millimetre
ranges17,18, compact gravimetry19–22, measuring the gravitational Aharonov–Bohm
efect9,23 and the gravitational constant2
, and testing whether the gravitational feld

Compositions of iron-meteorite parent bodies constrainthe structure of the pr...Sérgio Sacani
Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Mapping the Growth of Supermassive Black Holes as a Function of Galaxy Stella...Sérgio Sacani
The growth of supermassive black holes is strongly linked to their galaxies. It has been shown that the population
mean black hole accretion rate (BHAR) primarily correlates with the galaxy stellar mass (Må) and redshift for the
general galaxy population. This work aims to provide the best measurements of BHAR as a function of Må and
redshift over ranges of 109.5 < Må < 1012 Me and z < 4. We compile an unprecedentedly large sample with 8000
active galactic nuclei (AGNs) and 1.3 million normal galaxies from nine high-quality survey fields following a
wedding cake design. We further develop a semiparametric Bayesian method that can reasonably estimate BHAR
and the corresponding uncertainties, even for sparsely populated regions in the parameter space. BHAR is
constrained by X-ray surveys sampling the AGN accretion power and UV-to-infrared multiwavelength surveys
sampling the galaxy population. Our results can independently predict the X-ray luminosity function (XLF) from
the galaxy stellar mass function (SMF), and the prediction is consistent with the observed XLF. We also try adding
external constraints from the observed SMF and XLF. We further measure BHAR for star-forming and quiescent
galaxies and show that star-forming BHAR is generally larger than or at least comparable to the quiescent BHAR.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

1. INTRODUCTION
A crane is the type of machine mainly used for handling heavy loads in different industry branches: metallurgy, paper and
cement industry. By the construction, cranes are divided into overhead cranes and gantry cranes. Overhead and gantry
cranes are typically used for moving containers, loading trucks or material storage. This crane type usually consists of
three separate motions for transporting material. The first motion is the hoist, which raises and lowers the material. The
second is the trolley (cross travel), which allows the hoist to be positioned directly above the material for placement. The
third is the gantry or bridge motion (long travel), which allows the entire crane to be moved along the working area.
This paper presents the loading zone and unloading zone. Three-motors namely Main hoist, long travel And Cross travel
are used for accomplishing movements of electric overhead travelling cranes in desired directions.. PLC are used for
controlling the three motors using programs. Drives are used to control the speed of motors proportional to the weights.
SCADA techniques are used for monitoring and data acquisition and used as a communicating tool between the client,
PLC and other control systems of the crane.
2. BRIEF INTRODUCTION TO PLC AND SCADA
A digitally operating electronic apparatus which uses a programming memory for the internal storage of instructions for
implementing specific functions such as logic, sequencing, timing, counting and arithmetic to control through digital or
analog modules, various types of machines or process. Programmable Logic Controller (PLC) is used to control machines
and process . PLCs can be used with a wide range of control systems, which vary widely in their nature and complexity.
After programming the PLC, before starting a real process, the operator has to verify if the program is correct, i.e. if the
PLC correctly performs the predefined control task. Therefore, the operator monitors the states at input and output port of
the PLC. A usual way is to monitor all the states and program variables online, during the operation of PLC, with the
same programming environment which was used for programming the PLC. However, it is best to develop a physical

educational model of the system, where the operator manually enters the inputs of the PLC and monitors its output states.
However, this can take a long time depending on the complexity of the system. Also, this solution isn‟t modular because it
is difficult to rebuild the model if some changes are necessary. The most complex system for monitoring and control of
industrial processes which is widely used nowadays is Supervisory Control and Data Acquisition (SCADA) system. This
system requires use of communication protocols between the client on one side and PLC and other parts of control system
on the other side. Although the SCADA is standard monitoring and data acquisition system in industry, it isn‟t easy to
make, so it isn‟t appropriate in simple control systems, when it is necessary to make a simple cost-effective monitoring
system. The operator uses software simulator to activate certain inputs of the PLC, while the application receives the
information about output states of the PLC and it shows them graphically, i.e. in animation. This process is realized
through interface board which communicates with PC and controls/reads input/output ports of the PLC.

POWER SUPPLY: Provides the voltage needed to run the primary PLC components
I/O MODULES: Provides signal conversion and isolation between the internal logic- level signals inside the PLC and
the field‟s high level signal.
PROCESSOR: Provides intelligence to command and govern the activities of the entire PLC systems.
PROGRAMMING DEVICE: Used to enter the desired program that will determine the sequence of operation and
control of process equipment or driven machine.
Advantages of PLCs :
1. Less wiring
2. Wiring between devices and relay contacts are done in the PLC program.
3. Easier and faster to make changes.
4. Trouble shooting aids make programming easier and reduce downtime.
5. Reliable components make these likely to operate for years before failure.

Programmable Logic Controller (PLC) is used to control machine and processes. PLCs can be used with a wide range
of control systems, which vary broadly in their nature and complexity.
The most difficult system for monitoring and control of industrial processes which is widely used nowadays is
Supervisory Control and Data Acquisition (SCADA) system. This system needs use of communication protocols
between the client on one side and PLC and other part of control system on the other side.
The Crane normally used to run 24 hours without stoppage, which results in frequent electric failure. It was a major
issue regarding the operation of crane.
Using variable frequency drive (VFD) simulation fed in Ladder logic programming, the crane has been designed to run
at a variable speed and variable voltage to avoid the above software.
Designing of E.O.T Crane model by using Siemens make WINCC SCADA software and communicating it with
SIEMENS PLC and communicating with programmes is the main operation.
This VFD was successful to overcome this problem and hence PLC and SCADA has been designed to control the
motion of the electric overhead crane.
PLC is a Digital Electronic Device that uses a Programmable memory to store instruction and to implement function
such as Timing, Counting, Logic, Sequencing and Arithmetic in order to control the machines and their processes. Input
Devices such as switches, different types of sensors are used to control the input switching and output devices such as
motors solenoids are used to control the output circuitry. Input devices e.g. switches, and output e.g Motors.
Ladder Language:
LADDER LOGIC:
The Ladder logic is widely used in programming PLC where sequential control of a process or manufacturing operation
is required. It is a graphic Language and can be used to transcribe relay diagrams, and is suited to combinational
processing. It provides basic graphic symbols, contacts, coils, and blocks. Specific calculations can be executed within the
operation blocks. Any control task modifications are done by changing the program.

Based upon the steps discussed in the Methodology, the graphical user interface is designed in Simatic Software with the
help of WinCC, which makes the task easier. It has been cleared from SCADA picture that starting as well as running
performance of electric overhead travelling crane is improved and variable frequency drive simulation shows better
performance when compared with contactor logic and these will help us in reducing electrical failures and helps us in
improving the performance of electric overhead travelling crane.
4. CONCLUSION
PLC and SCADA today are advancing in terms of applicability and capability. The System works during normal
operation and greatly improved the automation processes with the use of the PLC ladder diagram. The ladder logic for
contactor logic and variable frequency simulation has been designed and comparison shows that variable frequency drives
based simulation shows better performance in starting as well running current for motions in desired directions at
different values of speed and troubleshooting and monitoring is easy.
5. FUTURE ENHANCEMENT
The system performance can be improved with simulation of electric overhead travelling crane of higher capacity rating
and these system can be implemented in any existing contactor logic system. In the further research, detailed ladder logic
has been explained for electric overhead crane.
