 Abstract

Undoped and Dy/ Eu doped Fe2O3 thin films were deposited onto glass substrates using SILAR method. The films were prepared at 60 SILAR cycles and further annealed at 300? C. The optical properties of the films were investigated using optical absorption spectra and optical constants were determined and their variation was plotted against wavelength. The direct band gap energy values were determined using Tauc�s plots and were found to be in the range of 2.95eV to 3.15eV. Lower absorbance is observed in doped films in comparison to the un-doped Fe2O3 films. However the band gap values of doped films are higher than the un-doped films. On annealing, the band gap values were found to decrease. The optical constants were found to have higher values at lower wavelengths and were constant in the visible region of the spectrum.

 Abstract

In general it is obvious that glaciers are receding worldwide. This fits for Afghanistan glaciers as well, mostly the Afghanistan glaciers are ?spreaded in the ?high plateau of Pamir and Hindu Kush Mountain in north-eastern Afghanistan. More than ??18% reduction of the glacier surface had been discovered in 2016 in ?area of Afghanistan�s glaciers ??(ICIMOD/WRD Glacier Mapping Team, Ministry of Water and ?Energy of Afghanistan) On the bases of remote ?sensing studies. The purpose of this study is to find glaciers� changes in a year time cycle in upper Kabul River Basin by conducting mass balance measurement observations and hydro meteorological data analyses. The Pir Yakh Glacier in Panjshir province of Afghanistan has been chosen as benchmark since 2018. This glacier is under observationyealy base observation by Geo Sceince Facutly of Kabul University and Ministry or Energy and Water (MoEW) of Afghanistan . The study revealed the total accumulated mass of the glacier is ?222,791.28? cubic meters w.e. ?and total ablated ?mass of the glacier is 1,759,768.70? cubic meters w.e. the overall balance of glacier mass comes ?with ?-1,536,977.42 cubic meter w.e./year in a negative rate or 3230 mm w.e. /year. There is no glacier observation from Afghanistan glaciers in the past. Access the glaciers is a challenge since the glaciers are determined in remote areas of cities and insecurity if main one.

 Abstract

In India external assistance has taken in several forms. It includes outright grants, loans, repayable in rupees and loans repayable in foreign currencies. It is absolutely necessary for an developing country to relay to a large extent on foreign assistance for economic development. Such aid becomes necessary mainly to provide foreign exchange for purchasing capital equipment and industrial raw material from outside and for supplementing the capital and industrial raw material from outside and for supplementing the capital supply from domestic sources. India also found substantive foreign assistance when decided upon policy of planned economic development. Thus in order to cover the investment gap and the balance of payment gap the government of India has borrowed externally on a large scale. On this background the study focus on the performance of external debt in India from 2015-2016 to 2019-2020 and also examine the growth of sources of external debt by using statistical tools such as CAGR and AGR for the same period.

 Abstract

Abstract There is strong evidence in mathematics education literature that students benefit extensively from Geometry concepts of mathematics in daily life. The benefits include developing an advanced level of mathematical thinking, spatial reasoning and conceptual understanding. The purpose of this study was to investigate students understanding on geometry course and to give effective method of teaching. The sample consisted of 36 students in ML11 section of first year students in KCTE 2019.The sampling technique was used two stages sampling, in the first stage section ML11 selected purposely and the two groups experimental group and control group of the study selected randomly by using Microsoft excel. The collected data were analyzed descriptively and by inferential statistics using software package social science students SPSS (20.1). The reliability of research questionnaire was tested by cronbach�s alpha (0.641) which is reliable, and validated by experienced mathematics teachers. This study followed by pre-test and post-test for both experimental and controlled group. Conceptual understanding of the students on topics of geometry was measured through open-ended questions and some findings were obtained. The intervention given was teaching with involving GeoGebra software instruction for experimental group, And teaching geometry without involving GeoGebra software instruction for the controlled group. Statistical analysis is conducted by firstly testing the normality of the data, by using Kolmogorov Smirnov test data were distributed normally. Then the homogeneity was checked and result shows that data are not homogein due to this t-test was executed. Data were analyzed with an independent samples t-test on gain scores for control and experimental groups. In the conceptual understanding test, the gain scores of the experimental group were found to be 0.42 standard deviations higher than that of the control group on the average. Therefore from this result the researcher concluded that teaching with GeoGebra may be an effective tool for teaching Geometry concepts.

 Abstract

The experiment was conducted in Department of Agronomy, College of Agriculture (RVSKVV), Gwalior (M.P.) during the Rabi season of 2017-2018. The trial was laid out in a randomized block design replicated three times with 10. All the integrated weed management practices gave more tuber yield than weedy check. Amongst different weed control treatments, two hand weeding (HW) at 20 and 40 DAP was the most effective treatment for reducing weed population and weed dry weight and improving the growth. On the basis of above findings, it may be concluded that the maximum potato yield and net return were obtained from two H. W. 20 and 40 DAP, followed by one H. W. at 20 DAP + straw mulching 5 t/ha at 25 DAP. In the scarcity of labourer, the farmer may chose the second option i.e., one H. W. at 20 DAP + straw mulching 5 t/ha at 25 DAP or straw mulching 5 t/ha at 5 DAP. B:C ratio was obtained higher in two H. W. 20 and 40 DAP followed by one H. W. at 20 DAP + straw mulching 5 t/ha at 25 DAP.

 Abstract

Under present study, the effect of Self-disclosure as a trait of personality, on adjustment is investigated. De and Singh self-disclosure Inventory was used for measuring self-disclosure of the respondents along with Mohsin-Shamshad Adaptation of Bell�s Adjustment Inventory. Self-disclosure Inventory was administered to all the respondents (N=480) and their scores were obtained. Then the median value of the scores was calculated. The respondents falling at and above the median were placed in high self-disclosure group and those falling below it were placed in low self-disclosure groups. On the basis of their scores on self-disclosure scale the respondents were divided into the high self-disclosure group (N=280) and the low self-disclosure group (N=200) taking median as the cut mark in the manner stated above. Then Mean, SD and SE of the scores were calculated for each dimension. Then Mohsin-Shamshad Adaptation Inventory was administered to the subjects of both the groups and their scores on all the dimensions of adjustment were collected. For the analysis and treatment of the scores t-test, r-test and chi-square test were employed. The results showed significant association of adjustment with self-disclosure. The high self disclosure group of subjects showed better adjustment as compare to the low self disclosure group of subject.

 Abstract

Imagine writing a test and the moment you read the question paper, you cannot recall a single thing you studied for? Or imagine forgetting your important documents at home right before an interview? Both these scenarios are nightmares for most of us. Both what�s common between the two of them is our memory, which was unable to perfom the function it has been especially designed for. The WHO, in 2009 estimated that nearly one out of every five youngster in the world undergoes some sort of emotional, mental or behavioural issues. This accounts for a huge chunk of youngsters who need immediate help. This is when Psycho Neurobics comes into the picture. This therapy acts like an Energy Therapy. We inhale the Cosmic Energy through the intricacies of our mind and transfer it to our body and the neuro framework. Various surveys have also reported Indian women who undergo stress and anxiety. This stress also comes with numerous amounts of major health concerns, treating of which, can be heavy for the pocket. With this research paper, we aim to calculate the efficiency of Psycho Neurobics on Mental Concentration and Memory Enhancement.

 Abstract

Depression is a serious malady. It has shown to affect people of all age groups and is a growing cause of suicides. The electrical activity of the brain is depicted through electroencephalogram (EEG) signals. Studies have shown that EEG signals are a major indication of a person�s emotional state and hence are used in a huge number of studies on depression assessment. Deep learning is gaining ground in depression assessment using EEG signals. This paper summarizes the various methods used to assess depression using EEG signals, through machine and deep learning techniques.

 Abstract

An open top chamber (OTC) of 4.77 m2 experiment was conducted to study the impact of different elevated atmospheric carbon dioxide levels (500, 450 and ambient 400 ppm) on the growth and yield of pigeon pea and black gram. The study was conducted on two pulse crops i.e. pigeon pea and black gram in open top chambers (OTC) to study the impact of elevated CO2 levels on its growth performance in comparison to natural climatic conditions. There was positive impact of different elevated CO2 levels on plant growth and yield parameter. The results indicate that under varying levels of increased CO2 had a progressive increase in plant height, number of branches per plant, number of pods per plant, pod length, pod weight and number of grains per pod. Maximum values were found under 500ppm CO2 level followed by 450 ppm which was significantly higher over ambient 400 ppm and natural conditions. Similarly higher yield attributes were found in pigeon pea and black gram under 500 ppm CO2 level followed by 450ppm CO2, natural conditions & ambient. Highest grain yield (120g plant-1) & straw yield was under 500ppm CO2 followed by 450ppm level, natural condition & ambient (400ppm) in both pigeon pea and black gram. The yield attributes also differed significantly. Thus the findings focussed that increasing the CO2 level up to 500 ppm may be beneficial in terms of increasing the productivity of these pulses in semi-arid regions of Gwalior district of Madhya Pradesh.

 Abstract

Geo polymer concrete is an alternative to cement concrete. Geo polymer concrete is produced by pozzalonic material such as fly ash ,GGBS etc, alkaline solution (sodium hydroxide ( NaOH )+sodium silicate(NaSiO3))with various molar concentration. Based on literature fine aggregate(river sand), coarse aggregate of size 20mm with elevated temperature curing is to be used. In this study, it is proposed to use granite waste instead of fine aggregate as a partial replacement. Then the strength characteristics and durability test are to be performed and the values will be compared with control concrete.
