Authors: Dileep K. , Srinath A. , Banapurmath N.R. , Umarfarooq M.A. , Sajjan A.M. 
Published: April 2023

This work investigated the effects of graphene and SiO2 addition on the mechanical and fracture properties of epoxy (80%) - Polylactic acid (PLA) (20 %) composites. Epoxy-PLA composites were loaded with graphene and SiO2 (0.1-0.5 wt. % with equal weightage of each filler), and were manufactured by bath sonication followed by manual casting. The tensile, flexural strength and fracture toughness of nanocomposites increased with an increase in filler concentration till it reached 0.3 wt. %. The addition of filler content higher than 0.3 wt. % drastically reduced the mechanical and fracture properties. The fractured surfaces from the tensile tests were examined using Scanning electron microscopy imaging to understand the effects of filler addition. The numerical analysis was also performed to simulate the impact of filler concentration on the tensile strength of nanocomposites using representative volume element (RVE) in ANSYS workbench.

Authors: Li Yangjinyu , Zou Li , Zhu Zhengjie 
Published: April 2023

S-N curve fatigue samples of titanium alloy welded joints have such a comparatively significant scatter, that results in the issue that the fatigue life prediction accuracy is not optimal. In this work, the titanium alloy welded joints' fatigue data is used as analysis data, and the neighborhood rough set reduction with improved firefly algorithm efficient method of fitting stress-life curves is set forth. The welded joint's fatigue decision system is built with fatigue data. The continuous iteration of the firefly algorithm is used as the search strategy, the neighborhood rough set is adopted to decrease attributes, and the major deciding elements of welded joints' fatigue life is identified. The fatigue characteristic domains are divided based on the neighborhood rough set reduction with improved firefly algorithm's key factor set, and the S-N curves can then be fitted to each domain individually. According to the goodness-of-fit analysis, the proposed approach can improve fatigue life accuracy and reduce sample scattering from fatigue.

Published: April 2023

In this study, a novel quasi-three dimensional hyperbolic high-order shear deformation theory (quasi-3D HHSDT) is developed for free vibration analysis of porous functionally graded plates (FGPs). There are six unknowns in the current displacement field, and no shear correction factor is required. The mechanical properties are varied continuously through the thickness of porous FG plates using a modified power law function while considering the effect of porosities on the plate’s structural integrity. Two distinct porosity distribution models are considered, including even and uneven porosity distributions. The Navier technique is employed to obtain the closed-form solutions of motion's equations. An exhaustive parametric study is presented to show the influence of the different parameters on the fundamental frequencies.

A 56-day feeding trial was conducted to determine the effect of lye processed Moringa seed meal (LMSM) on performance and blood indices of broiler chicken. A total of 150 one- day-old cobb breed broiler chicks were randomly allotted to five (5) dietary treatments replicated three times with ten chicks per replicate. The experimental diets were formulated with LMSM at inclusion levels of 0%, 5%, 10%, 15% and 20% designated as T1, T2, T3, T4 and T5 respectively. Data were generated for final body weight, total feed intake, daily feed intake (DFI), total weight gain, daily weight gain (DWG), feed conversion ratio and blood indices. Data obtained were subjected to Analysis of Variance (ANOVA). The result of the performance showed significant (P<0.05) influence of LMSM on final weight gain, weight gain, daily feed intake and feed conversion ratio at both phases. Birds on diet 0%, 5% and 10% recorded the highest weight gain while birds on 15% and 20% LMSM obtained the least value in the starter phase. Birds on control diet and 5% LMSM recorded the highest feed intake while the lowest was obtained on 20% diet. The best FCR was observed in birds fed control diet, 5% and 10% LMSM diet. Finisher broiler fed control diet, 5% and 10% recorded higher final weight and weight gain. Birds fed control diet recorded the highest feed intake while birds on 15% and 20% LMSM recorded the lowest. Birds fed control diet, 5% and 10% LMSM obtained better FCR. The feed cost per gain was cheaper when fed LMSM irrespective of the inclusion level. Heamatology and serum chemistry results revealed that all measured parameters showed no significant (P>0.05) influence of LMSM treatments on the birds except packed cell volume (PVC), Hemoglobin (Hb) and White blood cell, Glucose and ALP. Broiler chickens could be fed up to 10% LMSM at starter phase and 15%LMSM of finisher phase.

Published: April 2023

Surveys were conducted to assess the occurrence of viruses on pepper in 2020 and 2021 dry and wet seasons, respectively. Farms in Kaduna, Kano, Bauchi and Gombe States were visited for sampling and sample collection. Leaf samples from plants showing typical viral symptoms were collected for laboratory analysis. The genomic nucleic acid was isolated from the samples by phenol – chloroform separation and purification. The viral coat protein was amplified in Polymerase chain reaction using specific primers and sequenced. Sequences were aligned and used to search the GenBank database for viruses with high similarity. Sequences with high similarity scores were retrieved and used for phylogenetic analysis. Field occurrence of virus-like symptomatic pepper plants ranged from 10 – 70 %. Sequence analysis and phylogeny revealed that the virus infecting Pepper in locations surveyed was highly homologous (94.52%) to Pepper veinal mottle virus. This represents the first confirmation of Pepper veinal mottle virus on pepper in the study areas using novel molecular techniques. It is recommended that more extensive studies be conducted to cover the other northern states being the major pepper growing region of Nigeria. It should be emphasized that caution be exercised in the movement of planting materials across regions, especially between neighbouring countries because of the known impact of viruses on vegetable production in general, and pepper in particular.
