Phase-stabilized Y?O?–ZrO? nanocomposite were successfully synthesized in two different ratios (60% Y2O3-ZrO2 & 40% Y2O3-ZrO2) and systematically characterized to evaluate their potential for photocatalytic degradation applications. X-ray diffraction (XRD) analysis confirmed the formation of a stabilized cubic/tetragonal zirconia phase with fine crystallite size, indicating the effective incorporation of Y?O? into the ZrO? lattice. FTIR spectra revealed the characteristic metal–oxygen vibrational modes associated with Y–O and Zr–O bonding, further supporting the structural stability of the nanomaterials. UV–Visible absorption studies showed a strong absorption edge in the UV region with a reduced band gap, demonstrating enhanced photo-response suitable for photocatalysis. SEM analysis illustrated the formation of uniformly distributed nanosized particles with controlled morphology, which facilitates efficient charge separation during photocatalytic reactions. The photocatalytic studies confirmed that the Y?O?-ZrO? nanocomposite exhibit superior degradation efficiency toward organic pollutants under UV irradiation, attributed to their improved structural stability, optical activity, and surface morphology. These findings highlight the potential of Y?O?–ZrO? nanostructures as promising photocatalysts for environmental remediation applications.

The host plant, Pentaslanceolata, constitutes 77% of complete pollinators. We observed and labored out a total of 536 visits to this host plant. Oecophyllasmaragdina had 218 visits with more affinity, Papiliodemoleus (198), Tirumalaseptentrionis (177), and Euploea core (159). We recorded the top pastimes between 8.30 hours and 12.30 hours. 75% of the traveling endeavor finished for the duration of this period. Among the found foragers, the majority were E.core, P.demoleus, T.septentrionis, and P.polytes having two top intervals of vigorous visits.

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
