Authors: Nassarawa Sanusi Shamsudeen , Sulaiman Salamatu Ahmad 
Published: October 2021

Purpose: Culturally, consumption of local fermented skimmed milk (nono) is common in Northern Nigeria and many other parts of Africa. However, this is, associated with foodborne related diseases resulting from poor hygienic practices.
Methodology: Purposive sampling was used to collect a total of 12 different fermented products from Kano metropolis, Kano State, Nigeria.
Findings: The results obtained showed ranges of different parameters as Ph (4.890±0.01414 to4.450±0.07071), titratable acid value (0.315±0.06364 to0.270±0.0000), moisture content (92.090±10.5640 to 80.730±3.7760) and total solid (19.270±3.7760 to 7.910±10.5604). The total bacterial count ranged from (8.766 ±0.3512 × 103 CFU/ml(log104.94) to 1.150 ±0.0700 × 103 CFU/ml (log10 4.06), with fungal count of 2.400 ±0.2646 × 103 CFU/ml (log10 4.38) to 0.733 ±0.1528 × 103 CFU/ml(log10 3.87), coliform count of 14 to <3 (MPN/ml) and Staphylococcal count between the ranged of 8.567 ±0.7095 × 103 CFU/ml (log10 4.92) to 2.867 ±0.9504 × 103 CFU/ml (log10 3.46). The bacteria isolated were Staphylococcus spp, Bacillus spp, Micrococcus spp, Streptococcus, and E. coli, Moreover, the fungal isolates from the samples included Aspergillus niger, Aspergillus flavus, Mucor and Rhizopus stolonifera. The fermented skimmed milk consumed in the study area was found to be of low quality. Thus, awareness should be strengthened on hygienic methods of production, handling, and selling to the consumers.

ROLE OF FOREST DIVERSIFICATION IN PROMOTING TOURISM.A CRITICAL LITERATURE REVIEW
Authors: Kivuva Joyce 
Published: October 2021

Purpose: Global Tourism destinations provide different products which satisfy tourists with different interests, needs and wants. The general objective of the study was to establish the role of forest diversification in promoting tourism
Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps.
Findings: The study concludes that forest tourism products were positively and significantly influenced the tourism sustainability (r=0.258, p=0.001). This meant that a unitary increase in the forest tourism products leads to an increase in tourism sustainability by 0.258 units.
Majority of the tourists’ and destination operators agreed that cultural tourism experienced influenced tourism sustainability. Some of the cultural tourism practices experienced were visiting historical sites, tasting local food and drinks, listening to local music, witnessing local dancing, viewing local artifacts, visiting sacred sites, witnessing local basket making, sighting traditional homes, attending local cultural shows/events and local religious events and home staying in rural villages
Recommendations: The study recommends that forest tourism stakeholders should devise plans and ways of countering the challenges that face the forest tourism diversification These challenges included; inadequate relevant information about the forest tourism product; inadequate facilities in the forests such as rest centers, walking trails; poor quality services; unethical guiding practices such as request for tips, use of vulgar language; hostile residents; inadequate signage; unfavorable prices of forest activities; insecurity; unhealthy environment; poor communication facilities and inadequacy in tourism product diversity. These can be mitigated by building sustainable transport and communication infrastructure, encouraging community participation of the tourist resources, training tour guides, encouraging community visits to the sites and creating awareness on the importance to preserve tourist sites. The study suggested that cultural tourism practices in the indigenous forests in counties should be fully profiled and funds for its full establishment be allocated

Published: October 2021

Introduction: The Covid-19 pandemic continues to affect all aspects of human life, the most obvious of which may be its impact on the tourism industry, since it prohibits flights. All sectors of the world economy without exception, and restrictions on movement and travel are one of the first measures aimed at curbing the spread of the virus.
Purpose: The purpose of the study was to analyze the scope of the analysis in order to pay special attention to some of the best internationally recognized tourist destinations in the world, and taking into account the situation in Africa.
Methodology: Data was collected from previously published articles and this study used a mixed approach, using both qualitative and quantitative approaches. Secondary data has been collected from various published articles, libraries, newspapers, and conference reports that clearly show their relevance to our learning environment.
Findings: The conclusion of this study is that the tourism industry of countries that rely heavily on tourism income is most affected by the epidemic, while in Africa, due to the low tourism income in Africa, the impact of the epidemic on the tourism industry is relatively weak.
Recommendations: The study suggests that the Government should use the necessary technical, human and financial resources. The most important thing is that the owners of tourist products must adapt and innovate in their tourist offers in order to meet the demand for safe domestic tourism. This can prepare for international tourism and contribute to the development of tourism.
Diagnosis of Keratoconus with Corneal Features Obtained through LBP, LDP, LOOP and CSO
Authors: Subramanian P , Ramesh GP 
Published: October 2021

Keratoconus, by its name, is the condition of the eye wherein the cornea assumes a conical shape due to the thinning and protrusion of the cornea. Keratoconus, though bilateral, can be asymmetric in that it can progress differently in the eyes of the patient. Keratoconus can start from early adulthood and progress till the age of 40. Early detection of keratoconus is vital in preventing vision loss or costly repairs. The diagnostic tools available range from keratoscope to videokeratoscope but involves human efforts and thereby human errors. Automatic detection of keratoconus is required for large screening camps. With the advances in artificial intelligence techniques for medical diagnosis, new algorithms and techniques have been developed for the early and rapid screening of keratoconus, which aids clinicians in fast diagnosis. Artificial Neural Networks, Support Vector Machines, Radial Basis Function Neural Networks, Decision Trees, Computational Neural Networks, and various optimisation techniques have been used in different studies. The progression of keratoconus is identified by analyzing the shape of the cornea with Local Binary Pattern (LBP), Local Directional Pattern (LDP), Local Optimal Oriented Pattern (LOOP), and Cat Swarm Optimization (CSO) to detect the changes in cornea edges. The image processing with the CSO algorithm optimizes the result for the changes in the cornea and keratoconus detection. A new automated solution for detecting keratoconus is presented that employs texture analysis techniques such as LBP, LDP, LOOP, and CSO. The CSO extracts morphological and granular features from images of the cornea. The proposed method can be used to detect keratoconus by identifying the cornea shape change and improving clinical decisions. Further research can be in the way of grading the level of keratoconus.

AbstractSilicosis is a fatal occupational pulmonary disease that is characterized by irreversible replacement of lung parenchyma by aberrant Exracellular matrix (ECM). Metabolic reprogramming is a crucial mechanism for fibrosis. However, how the metabolic rewiring shifts the ECM homeostasis toward overaccumulation remains unclear. Herein, a phenotype with reduction in fatty acid oxidation (FAO) but enhanced glycolysis in myofibroblasts is shown. Perturbation of the glycolytic and FAO pathways, respectively, reveals distinct roles in the metabolic distribution of ECM deposition and degradation. Suppressed glycolysis leads to a decrease in insoluble ECM, primarily due to the inhibition of ECM‐modifying enzyme activity and a decrease in glycine synthesis. Notably, promoted FAO facilitates the intracellular degradation pathway of ECM. In addition, the findings revealed that hypoxia‐inducible factor‐1 alpha (HIF‐1α) serves as a crucial metabolic regulator in the transition from FAO to glycolysis, thereby playing a significant role in ECM deposition in silica‐induced pulmonary fibrosis. Further, the promotion of FAO, inhibition of glycolysis and HIF‐1α reduce ECM production and promote ECM degradation, ultimately impeding the progression of fibrosis and providing therapeutic relief for established pulmonary fibrosis in vivo. These findings unveil the metabolic rewire underpinning the deposition of ECM in silica‐induced lung fibrosis and identify novel targets for promoting regression of pulmonary fibrosis.

AbstractKaryotype diversity plays an important role in speciation and diversification. However, gymnosperms, particularly conifers, exhibit remarkable karyotype uniformity. To explore the evolutionary processes shaping karyotypes in gymnosperms, the karyotype evolutionary history is reconstructed through comparative genomic analyses. Synteny analysis confirms the absence of ancient polyploidy in conifers and its rarity across the gymnosperms as a whole. Further analysis reveals convergent patterns of reciprocal translocations between nonhomologous chromosomes in conifer genomes. Centromeric‐centromeric reciprocal translocations (CRTs) have been identified as the primary mechanism of karyotype evolution in conifers, while telomeric‐centromeric reciprocal translocations (TRTs) significantly contributed to descending dysploidy within Cupressales. A graph‐based method is utilized to infer the detailed evolutionary pathways from the proto‐gymnosperm karyotype (n = 12) to modern conifer karyotypes (n = 11–12). In conclusion, the scarcity of both polyploidy and dysploidy contributes to the karyotype uniformity of gymnosperms and potentially also to their lower species richness compared to angiosperms. However, the pervasive CRTs and occasional TRTs underlie this “apparent uniformity”, supporting the “karyotype orthoselection” hypothesis. This study provides new insights into the mechanisms maintaining karyotype uniformity in conifers and the role of karyotype evolution in their diversification.

AbstractCrystalline thermoelectric materials, especially SnSe crystals, have emerged as promising candidates for power generation and electronic cooling. In this study, significant enhancement in ZT is achieved through the combined effects of lattice distortions and band convergence in multiple electronic valence bands. Density functional theory (DFT) calculations demonstrate that cation vacancies together with Pb substitutional doping promote the band convergence and increase the density of states (DOS) near the Fermi surface of SnSe, leading to a notable increase in the Seebeck coefficient (S). The complex defects formed by Sn vacancies and Pb doping not only boost the Seebeck coefficient but also optimize carrier concentration (nH) and enhance electrical conductivity (σ), resulting in a higher power factor (PF). Furthermore, the localized lattice distortions induced by these defects increase phonon scattering, significantly reducing lattice thermal conductivity (κlat) to as low as 0.29 W m−1 K−1at 773 K in Sn0.92Pb0.03Se. Consequently, these synergistic effects on phonon and electron transport contribute to a high ZT of 1.8. This study provides a framework for rational design of high‐performance thermoelectric materials based on first‐principles insights and experimental validation.

AbstractAneuploidy eggs are a common cause of human infertility, spontaneous abortion, or trisomy syndromes. The spindle assembly checkpoint (SAC) plays a crucial role in preventing aneuploidy in oocytes, yet it is unclear if additional mechanisms exist to ensure oocyte adherence to this checkpoint. It is now revealed that the microtubule‐associated protein NUSAP can prevent oocytes from evading the SAC and regulate the speed of the cell cycle. Mechanistically, the study identifies NUSAP as a novel stabilizer of the E3 ubiquitin ligase APC/CCDH1, protecting CDH1 from SCFBTRC‐mediated degradation. Depletion of NUSAP reduces CDH1 protein level, leading to abnormal spindle assembly and chromosome alignment, and disrupting the balance of cell cycle proteins. This misregulated balance causes oocytes to evade the SAC. Consequently, these abnormal oocytes not only fail to arrest at metaphase but also accelerate the cell process, ultimately resulting in the production of aneuploid eggs. Together, the findings not only clarify the existence of mechanisms that ensure oocytes compliance with the spindle assembly checkpoint but also expand the new functions of NUSAP beyond its role as a microtubule‐ associated protein.

Published: December 2024

AbstractHigh‐performance boiling surfaces are in great demand for efficient cooling of high‐heat‐flux devices. Although various micro‐/nano‐structured surfaces have been engineered toward higher surface wettability and wickability for enhanced boiling, the design and fabrication of surface structures for realizing both high critical heat flux (CHF) and high heat transfer coefficient (HTC) remain a key challenge. Here, a novel “electrode‐transpose” all‐electrochemical strategy is proposed to create superhydrophilic microporous surfaces with higher dendrites and larger pores by simply adding an electrochemical etching step prior to the multiple electrochemical deposition steps. Enabled by the high nucleation density and high wicking capability, a high boiling performance is shown on such “etching‐then‐deposition” surfaces with simultaneously high CHF of 2,641 ± 10 kW m−2 and high HTC of 214 ± 6 kW (m2 K)−1, which are more than 2.5 and 4.3‐fold enhanced from those on smooth surfaces, respectively. A very stable morphology and boiling performance of such surfaces subject to consecutive tests are also shown. Using this strategy, such superhydrophilic microporous layers are fabricated on curved surfaces with larger areas, both on spheres and slender cylinders, and demonstrate excellent boiling performance in quenching tests. This facile, geometry‐adaptive, durable, and scalable strategy is very promising for making high‐performance boiling surfaces for large‐scale industrial applications.
