Published: September 2023

Water quality management has been considered one of the most important aspects of pond aquaculture for many years, but less attention has been given to the management of pond bottom soil. The quality of pond bottom soils greatly impacts the productivity of ponds with respect to fish production. The objective of this study is to explain the nutrient profile of bottom soils of selected regular and integrated ponds in the Ibadan metropolis, Oyo State, Nigeria. Bottom soils and water samples of three regular and three integrated ponds in Ibadan metropolis, Nigeria were sampled. In each pond, soil samples were sampled from two different points at three depths each (inlet and outlet) of 0-10cm,10-20cm and 20-30cm. Soil samples were also analysed for; pH, organic carbon, organic matter, nitrogen, phosphorous and potassium. The productivity of the ponds was evaluated using the measured parameters in line with standard procedures. The data obtained were analyzed using descriptive statistics, one-way analysis of variance, correlation and regression analysis. The organic carbon of all the ponds indicated that they were all suitable for aquaculture production with average values ranging from 0.82% to 2.66%. Three of the ponds’ bottom soil were of mineral soils having medium organic carbon of mean values 1.81%, 1.73% and 2.66% for integrated pond 3, regular ponds 1 and 3 respectively while the three other ponds were of organic soils having high organic carbon concentration of mean values 1.06%,0.82% and 1.01% for integrated ponds 3and 2 and regular pond 2. The pond soils were all neutral except two of the regular ponds with average values ranging from 7.00 to 9.60. All the mean values of phosphorous in the soil indicated that the soils were of high productivity and highly suitable for aquaculture production. Mean soil phosphorous concentration values 0.33%, 0.30%, 0.26%, 0.27%, 0.28% and 0.34% of integrated ponds 1 to 3 and regular ponds 1-3 respectively showed that the ponds were highly suitable for fish culture with respect to ability to synthesize phytoplankton and zooplanktons. The organic carbon concentration and the phosphorous concentration of all the ponds showed high productivity. The pH and the nitrogen concentration of all the ponds showed high productivity. Generally, the evaluation of the ponds in line with the three standard procedures indicated that the integrated pond soils was more productive for fish culture than the regular pond soils.

The aim of the study is to identify the suitable modified atmospheric storage condition required for long term storage of groundnut (Arachis hypogaea L.) variety TMV (Gn) 13. The experiment was conducted during 2022 at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. The groundnut pods and kernels were subjected into different storage conditions viz., pods stored in gunny bag, kernels stored in gunny bag, kernels stored in polythene bag, kernels stored with N₂gas and kernels stored in vacuum conditions. The results revealed that pod storage recorded the maximum germination percentage (73%), root length (14.5cm), shoot length(14.3cm), dry matter production (3.47 g 10 seedlings -1) and vigour (2136). Similarly, enzymes viz., dehydrogenase( 0.72 OD value), peroxidise (1.29U mgˉ¹ protein minˉ¹), alpha amylase (13.60mg maltose min-1) and catalase activity (1.253 µmolH₂O₂ minˉ¹gˉ¹ protein) were also maximum in pod storage with minimum harmful effect of pest(0.6%) and fungus incidence(17%). The nitrogen storage conditions also have maximum enzyme activity viz., dehydrogenase (0.64 OD value), peroxidise (1.24U mgˉ¹ protein minˉ¹), alpha amylase (13.58 mg maltose min-1) and catalase activity (1.220 µmolH₂O₂ minˉ¹gˉ¹ protein) with minimum harmful effect of pest (0.6%) and fungus incidence (20%). Present study, it is concluded that groundnut kernels stored under modified atmospheric storage i.e. nitrogen gas storage can maintain the seed longevity by minimizing the deterioration process in groundnut equally as that of pod storage. Further, it will helps to minimize the expenditure towards transport and storage.

Aim of the Study: To compare the efficacy of H&E and PAS staining techniques in the demonstration of TIP among patients attending Federal Medical Centre Keffi, Nasarawa state. Study Design: The study is a retrospective study, a total of 129 paraffin-embedded tissue blocks of patients who were diagnosed of TIP between January 1st 2013 and December 31st 2022 were retrieved from the archives of Histopathology laboratory and examined. Ten patients (10) with incomplete data were excluded.
Methodology: A semi structured questionnaire was used to collect demographic data. The tissue blocks were sectioned at 4um and stained using Haematoxylin and Eosin (H&E) staining technique and Periodic Acid Schiff (PAS) technique. The microscopic examination was done using x10 and x40 objectives of the Olympus light microscope.
Results: The study showed that males were more affected with TIP than females with ratio 1.6: 1. Ages of patients ranged between 6 months-77 years with mean age of 24.8+1.87 years. The highest number of TIP cases was recorded in December. The ileal segment was the most perforated among the intestinal segments. The socioeconomic status of patients, availability of potable water supply as well as hygiene and sanitary practices were discovered to be key factors in typhoid fever infection and treatment outcomes.
Conclusion: Although, both PAS and H&E staining techniques showed favorable features, the PAS technique gave better contrast and also revealed the perforation sites better than H&E at P<0.001. Hence, the PAS technique should be done alongside the H&E in the laboratory investigation of intestinal tissues.

Published: September 2023

Aims: This paper aims to investigate the costs and benefits of regional connectivity in Bangladesh from the economic perspective through using the analytical tools of benefit-cost analysis.
Study design: The study is conducted based on forecasted secondary data from different related published sources. A qualitative stakeholder survey is conducted to evaluate the intended impact of regional connectivity on the economy of Bangladesh.
Methodology: The study uses qualitative research tools to assess the impact of bilateral or multilateral connectivity and uses the tools of benefits-costs analysis (NPV, BCR, and IRR) applied to evaluate the effectiveness of regional connectivity from bilateral and multilateral perspectives. Our key hypothesis is that ‘regional connectivity improves benefits’.
Results: The study shows that Bangladesh can gain from connectivity. However, gains from regional connectivity, especially, bilateral connectivity is very sensitive to the changes in the variables particularly, transshipment charge, volume of transshipment, and cost of building physical infrastructure. With modest values of the parameters, we find that connectivity generates a positive net present value, if Bangladesh can charge rationally against the cost of building infrastructure. From the stakeholders’ point, connectivity is beneficial, particularly multilateral connectivity generates more net benefit than the bilateral connectivity. Besides, the economic costs, the security concern can play a big effect on the social cost of such connectivity. Meanwhile, grave concern is aired on incurring a huge project cost, if Bangladesh implements the project with a higher interest tide loan from India. Moreover, the imposition of congestion fees, water pollution, and traffic fees derive the benefit from transit facilities.
Conclusion: The net gains from regional connectivity depend on trading patterns’ transshipment of goods, trade creation, and trade diversion among the partners through the connectivity process. Bangladesh needs to adopt gains-optimizing strategies for fixing the direct and indirect fees. Bangladesh should prioritize the silk-route connectivity more than the Asian Highway to attract FDI and sunset industry from China.

Published: September 2023

AbstractIn Amami‐Oshima, folk houses are characterized by the “HIKIMUN construction” system, which is different from other wooden construction systems of the Japanese main island. Big beams that are dropped into primary posts are called “HIKIMUN.” This study aimed to clarify the regional characteristics of HIKIMUN construction systems and their determining factors. Ten HIKIMUN folk houses in mountainous, plain, and island areas were studied. According to the survey results, four types of HIKIMUN construction systems—Basic, Discontinuous, Extended, and Two levels—two types of HIKIMUN joints—Unprocessed and Watariago—and three types of floor level joints—Makura, Kusabi, and Combined—were identified. The regional characteristics of each type were also clarified.

AbstractResisting extreme loading and thermal ablation encountered by aerospace devices demands for high performance engineering materials. Aerogels have achieved satisfactory thermal insulation but the intrinsic brittleness of porous skeletons fail to ensure their normal operation under severe stress fields. Herein, aramid nanofibers (ANFs) are processed into tough 3D aerogel monoliths via a multi‐scale toughening strategy, involving unidirectional freeze‐casting‐enabled microstructure orientation and acid‐assisted nanofiber cross‐linking. Scalable production of ANFs aerogels is realized through fast air‐drying without excessive energy consumption. The aligned sheets in ANFs aerogels enable extreme thermal conductivity of 15.8 mW m−1 K−1, superinsulation from −130 to 300 °C, and durable combustion protection for 20 min. Particularly, highly aggregated nanofibers assemble into dense ANFs skeletons, endowing the tough aerogels with superior specific tensile strength (89 MPa cm3 g−1), ultra‐high toughness (1.3 MJ m−3), and impressive fracture energy (7.36 kJ m−2). Such mechanical properties are highly resistant to harsh environments, including water erosion (7 days) and high temperature baking (30 days). Moreover, ANFs aerogels exhibit two to three times more energy dissipation than commercial foams against ballistic impact at 140 m s−1. This integrated mechanical and thermal robustness may pioneer the potential application in impact‐thermal coupled safeguard for aerogel materials.

Published: September 2023

AbstractLithium‐sulfur batteries (LSBs) are regarded as a highly promising next‐generation energy storage technology due to their exceptional theoretical capacity and energy density. However, the practical application of these batteries is hindered by several challenges, including significant volume change of active materials, severe shuttle effect of lithium polysulfides, inadequate electronic and ionic conductivity, and safety concerns. These issues are particularly pronounced in cathodes with high sulfur loading, which are essential for the effective implementation of LSBs. Binders are an essential constituent of sulfur cathodes, and they perform a crucial function in enhancing the efficacy of LSBs, particularly when subjected to high sulfur loading. A considerable amount of research has been conducted to investigate the potential of multifunctional binders to tackle the aforementioned challenges associated with LSBs. This article provides a comprehensive overview of the various roles that advanced multifunctional binders play in LSBs, including but not limited to preserving electrode integrity, capturing lithium polysulfides, regulating Li2S deposition, accelerating reaction kinetics, enhancing ionic and electronic conductivity, promoting sulfur cathode safety, and safeguarding the environment. Additionally, the paper outlines the challenges and prospects for future research endeavors aimed at creating innovative multifunctional binders and improving the overall performance of LSBs.

Published: September 2023

AbstractRecent advances in the field of ophthalmology show great potential in the design of bioengineered constructs to mimic the corneal stroma. Hydrogels based on synthetic supramolecular polymers, are attractive synthetic mimics of the natural highly hydrated corneal stroma. Here, a fully synthetic corneal stromal construct is developed via engineering of an injectable supramolecular hydrogel based on ureido‐pyrimidinone (UPy) moieties. The hydrogel displays a dynamic and tunable behavior, which allows for control of biochemical and mechanical cues. Two hydrogels are developed, a fully synthetic hydrogel functionalized with a bioactive cyclic arginine‐glycine‐aspartate UPy (UPy‐cRGD) additive, and a hybrid hydrogel based on UPy‐moieties mixed with collagen type I fibers. Both hydrogels supported cell encapsulation and associated cellular deposition of extracellular matrix (ECM) proteins after 21 days. Excitingly, the hydrogels support the activation of isolated primary keratocytes into stromal fibroblasts as well as the differentiation toward more quiescent corneal stromal keratocytes, demonstrated by their characteristic long dendritic protrusions and a substantially diminished cytokine secretion. Furthermore, cells survive shear stresses during an injectability test. Together, these findings highlight the development of an injectable supramolecular hydrogel as a synthetic corneal stromal microenvironment able to host primary keratocytes.

AbstractThe highly contagious tuberculosis is a leading infectious killer, which urgently requires effective diagnosis and treatment methods. To address these issues, three lipophilic aggregation‐induced emission (AIE) photosensitizers (TTMN, TTTMN, and MeOTTMN) are selected to evaluate their labeling and antimicrobial properties in vitro and in vivo. These three lipophilic AIEgens preserve low cytotoxicity and achieve real‐time and non‐invasive visualization of the process of mycobacteria infection in vitro and in vivo. More importantly, these AIEgens can be triggered by white light to produce reactive oxygen species (ROS), which is a highly efficient antibacterial reagent. Among these AIEgens, the TTMN photosensitizer has an outstanding antibacterial efficacy over the clinical first‐line drug rifampicin at the same therapeutic concentration. Interestingly, this study also finds that TTMN can increase the expression of pro‐inflammatory cytokines in the early stage of infection after light irradiation, indicating an additional pro‐inflammatory role of TTMN. This work provides some feasibility basis for developing AIEgens‐based agents for effectively destroying mycobacterium.

AbstractRenal cell carcinoma (RCC) is a common urological malignancy and represents a leading threat to healthcare. Recent years have seen a series of progresses in the early diagnosis and management of RCC. Theranostic lipid nanoparticles (LNPs) are increasingly becoming one of the focuses in this field, because of their suitability for tumor targeting and multimodal therapy. LNPs can be precisely fabricated with desirable chemical compositions and biomedical properties, which closely match the physiological characteristics and clinical needs of RCC. Herein, a comprehensive review of theranostic LNPs is presented, emphasizing the generic tool nature of LNPs in developing advanced micro‐nano biomaterials. It begins with a brief overview of the compositions and formation mechanism of LNPs, followed with an introduction to kidney‐targeting approaches, such as passive, active, and stimulus responsive targeting. With examples provided, a series of modification strategies for enhancing the tumor targeting and functionality of LNPs are discussed. Thereafter, research advances on applications of these LNPs for RCC including bioimaging, liquid biopsy, drug delivery, physical therapy, and gene therapy are summarized and discussed from an interdisciplinary perspective. The final part highlights the milestone achievements of translation medicine, current challenges as well as future development directions of LNPs for the diagnosis and treatment of RCC.

Published: September 2023

AbstractA novel smart fluorescent polymer polyethyleneimine‐grafted pyrene (PGP) is developed by incorporating four stimuli‐triggers at molecular level. The triggers are amphiphilicity, supramolecular host–guest sites, pyrene fluorescence indicator, and reversible chelation sites. PGP exhibits smart deformation and shape‐dependent fluorescence in response to external stimuli. It can deform into three typical shapes with a characteristic fluorescence color, namely, spherical core–shell micelles of cyan‐green fluorescence, standard rectangular nanosheets of yellow fluorescence, and irregular branches of deep‐blue fluorescence. A quasi‐reversible deformation between the first two shapes can be dynamically manipulated. Moreover, driven by reversible coordination and the resulting intramolecular photoinduced electron transfer, PGP can be used as an aqueous fluorescence ink with erasable and recoverable properties. The fluorescent patterns printed by PGP ink on paper can be rapidly erased and recovered by simple spraying a sequence of Cu2+ and ethylene diamine tetraacetic acid aqueous solutions. This erase/recover transformation can be repeated multiple times on the same paper. The multiple stimulus responsiveness of PGP makes it have potential applications in nanorobots, sensing, information encryption, and anticounterfeiting.
