Potato is cultivated in plain and hilly area of eastern zone of Nepal and adjoining area of India. It is an important ingredient of vegetables- boiled, fried and spicy used in daily diet. Potato is grown a little in eastern zone against the demand and mostly imported from India. Potato requires a wide range of soil- sandy loams, slit loams, loams and peat. The tuber is rich in starch. The varieties of potato such as Kufri Red, Kufri Sinduri have been developed in Central Potato Research Institute, Simla. The survey of potato cultivation was completed on Date 15/03/2022 at Devanganj, Sunsari district of Province no 1. Some branches of potato were suffering from leaf roll disease by the pathogen Potato leaf roll virus (PLRV). Polero Virus transmitted by green peach aphid Myzus persicae. Severity of the disease was 4-8%. Identification of the potato leaf roll virus was according to Mehrotra (1980)21, Gibbs (1969)9, Gibbs & Harison (1976)12, Gibbs, et al. (1966)10, Nagaich, et al.

The aim of the present study was to improve the solubility and bioavailability of a poorly water-soluble drug in human body, using a solid dispersion technique. Solubility and dissolution rate is an important physicochemical factor affecting absorption of drug and its therapeutic effectiveness. Consequences of poor aqueous solubility would lead to failure in formulation development. The poor solubility of drug substances in water and their low dissolution rate in aqueous G.I.T fluid often leads to insufficient bioavailability. In the present investigation, an attempt was made to improve the solubility and dissolution rate of a poorly soluble drug, Eprosartan by solid dispersion method using skimmed milk powder as carrier. Four different formulations were prepared with varying drug:carrier ratios viz.1:1, 1:3, 1:5 and 1:9 and the corresponding physical mixtures were also prepared. The formulations were characterized for solubility parameters, drug release studies and drug-polymer interactions by using phase solubility studies, dissolution studies; XRD analysis, FTIR spectrum, TLC analysis and UV overlay spectra. All the formulations showed marked improvement in the solubility behaviour and improved drug release. Formulation containing drug: polymer ratio of 1:9 showed the best release with a cumulative release of 82.67 % as compared to 6.919 % for the pure drug. The interaction studies showed no interaction between the drug and the carrier. It was concluded that skimmed milk powder as a carrier can be very well utilized to improve the solubility of poorly soluble drugs.

The study aims to investigate projects submitted by graduating students to the College of Engineering of Afe Babalola University, Ado-Ekiti, Nigeria using citation analysis. A descriptive survey design was used for the study. A total of 406 copies of undergraduate projects submitted between 2015 –2017 to the College of Engineering of the institution were retrieved. Data were extracted manually from the title pages and reference lists of each of the project examined and analyzed. The findings show that from 12,741 citations made in all the projects submitted for the 7 programmes run in the College of Engineering, information materials mostly cited by students is journals followed by books and seminar/conference proceeding. The average number of citation per project is 31.38. The students cited more of recent materials, and more of foreign authors compared to that of Nigerians authors. The research provides an opportunity for the library in building their collection towards the area that will meet the needs of engineering students since the analysis shows the preferred formats of resources accessed by the students in their discipline. It was recommended that the supervisor should put more efforts in guiding the students attached to them on how to reference and carry out proper citations of materials consulted.

If a nuclear reactor happened to be prompt critical - even very slightly - the number of neutrons would increase exponentially at a high rate, and very quickly the reactor would become uncontrollable by means of cybernetics. The prompt neutron flux spectrum of the compact core of the Ghana’s miniature neutron source reactor (MNSR) was understudy using the Monte Carlo method. 20484 energy groups combined for all three categories of the energy distribution, thermal, slowing down and fast regions were modeled to create small energy bins. The moderator, the inner irradiation channels, the annulus beryllium reflector and the outer irradiation channels were the region monitored. The prompt thermal neutrons recorded it highest flux in the inner irradiation channel with a peak flux of (1.2091 ± 0.0008) × 1012 n/cm2•s, followed by the outer irradiation channel with a peak flux of (7.9393 0.0056) × 1011 n/cm2•s. The beryllium reflector recorded the lowest flux in the thermal region with a peak flux of (2.3328 0.0004) × 1011 n/cm2•s. The peak values of the thermal energy range occurred in the energy range 1.8939× 10-08 MeV – 3.7880× 10-08 MeV. The inner irradiation channel again recorded the highest flux of (1.8361 0.0301) × 1009 n/cm2•s at the lower energy end of the slowing down region between 8.2491× 10-01 MeV – 8.2680 × 10-01 MeV, but was over taken by the moderator as the neutron energies increase to 2.0465 MeV. The outer irradiation channel recorded the lowest flux in this region. In the fast region, the core, where the moderator is found, the moderator recorded the highest flux as expected at a peak flux of (2.9143 0.0195) × 1008 n/cm2•s at 6.961MeV. The inner irradiation channel recorded the second highest flux while the outer channel and annulus beryllium recorded very low flux in this region. The final k-effective contribution from only prompt neutrons is 0.9956, hence the Ghana MNSR not prompt critical

In this manuscript, we will discuss a definition of Laplace transforms with some of their properties. with common applications. This will be according to some types and ranks of differential equations. We will also show how to find the inverse Laplace transform. We also showed what are differential equations of the third order and how the Laplace transform is applied to them. In addition to (Heterogeneous Linear Equations), which is a type of differential equation. The articles of this manuscript were interspersed with a mention of some types of solutions.

This paper is deliberate the psycho study in earthquake affected area in Nepal. Earthquake is one of the fatal natural disasters we have regularly experienced. Nepal and its adjacent areas are vulnerable to very high magnitude of earthquake. On the basis of investigation it has been found that recent earthquakes had destructed many human lives and their properties in Nepal and north India. The earthquake was considered to be the main cause for avalanches, landslides, slumps, many creaks and fissures in the adjacent area of Nepal. The study endeavors to examine the nature, extent, causes and consequences of the tremor of quakes.

The Americium-Beryllium neutron irradiation facility at the National Nuclear Research Institute (NNRI), Ghana, was re-designed with a 20 Curie source using MCNP5 to investigate the maximum amount of flux that is produced by the source. The main objective was to enable us harness the maximum amount of flux for optimization of neutron activation analysis. The design was compared with the values recorded in the existing Am-Be source design. The thermal neutron flux ranges from (1.80 ± 0.0008) × 106 n/cm2.s to (2.28 ± 0.0008) × 105 n/cm2.s. The epithermal neutron flux ranges from (8.20 ± 0.0008) × 105 n/cm2.s to (3.73 ± 0.0008) × 104 n/cm2.s and that of the fast neutron flux ranges from (4.20 ± 0.0008) × 105 n/cm2.s to (1.72 ± 0.0008) × 104 n/cm2.s. The keff of the Am-Be source design was obtained as 0.00115 ± 0.0008.

The Retail employees are driven by the same universal motivational theories. Though their life style and the aspirations in economic terms are different in the Indian society, their behaviour towards the motivational stimuli are almost the same as employees of other industry. When we apply Maslow’s need hierarchy and check where the preference of the Retail employees lay. They are concentrated as social and elite needs as the lower physiological and basic needs are taken care of easily given their economic stand in the society. Work is an important event, a fact that is inevitable in the life of an individual whatever form, it is done; it is an activities and source of satisfaction ones needs. Employee try to find satisfaction in what they do and as a result the manager should be able to understand the problems faced by his workers and find a way of satisfying their needs and aspiration The general assumption is that an adequately motivated worker will in turn give in his or her best towards the attainment of a general consensus. The observations of the present study corroborate the fact that, there is a strong positive relationship between employee motivation and His/her productivity. 98% of the employees responded that they will get motivated by their working environment. The kind of monitoring they have from their managers, the compensation what they get from the company is also important motivator to retain them. Over 90% of the employees say that quality of their working environment motivates them to work with enthusiasm, working culture, behaviour and attitude about their work. Based on the above respondents response we can say that there is a relation between employee motivation and his/her productivity.
