Humanitarian Logistics is a critical set of actions that takes place during natural or man-made disasters to save lives and property. However, the subject is under-researched in comparison to business logistics in profit-making firms where profit is the primary motivation for existence. The main goal of this study was to examine the role of humanitarian logistics management practices on drought management response in Kenya, with the following specific objectives of the study: to examine the role of transport management drought management response in Kenya, to evaluate the role of inventory management drought management response in Kenya, to examine the role of order processing drought management response in Kenya, and to establish the influence of information flow on drought management response in Kenya. The study used a cross-sectional survey. The study's target population was 270 personnel from the National Drought Management Authority in 23 Arid and Semi-Arid Lands counties. A semi-structured questionnaire was distributed via e-mail survey and hand delivery. Secondary data was gathered from both public and unpublished records. The questionnaire's validity and reliability were assessed. The data was analyzed using both quantitative and qualitative methodologies with the help of the SPSS software program version 25. The study discovered that both transport management practices, inventory management practices, order processing, and information flow as humanitarian logistics management practices played a significant role in drought management response in Kenya; thus, the study recommended that managers in humanitarian organizations. Kenya should include humanitarian logistics management practices in their strategic plan, particularly investment in transport management practices, inventory management practices, order processing, and information flow, which may make it easier to bring about innovation in the organization and good information sharing to both suppliers and clients.
Las razones de un destierro: a propósito de las acusaciones de Alexandra von Teuffenbach contra el fundador de Schoenstatt
Authors: Serrano del Pozo Ignacio 
Published: July 2023

El objetivo de este trabajo es problematizar la lectura que Alexandra von Teuffenbach ha hecho sobre el actuar del sacerdote alemán Joseph Kentenich, a quien denuncia por haber cometido abuso de poder, abuso espiritual y emocional contra un grupo de Hermanas de María en los años 50. De acuerdo con la investigadora, una revisión de los expedientes vaticanos daría cuenta de que la razón por la que Kentenich habría sufrido un exilio durante 14 años fuera de Schönstatt, correspondería a una medida del visitador pontificio, el jesuita neerlandés Sebastian Tromp, para proteger a la comunidad de mujeres consagradas contra su abusador. El propósito de este artículo es mostrar que la cuestión juzgada por el Santo Oficio se mueve en otro plano, el que se debiese abordar desde una hermenéutica más objetiva que haga justicia a las palabras utilizadas en los documentos oficiales, así como a las mismas expresiones emitidas por el encargado de la visitación. En esa línea, se analiza en este trabajo la crítica dirigida por Tromp a la espiritualidad de Schoenstatt y de su fundador por falso misticismo, falso culto personal y falsa dirección espiritual. Para este trabajo se ha utilizado la reciente edición de los informes apostólicos publicados por Patris Verlag, archivos sobre los que sólo recientemente se ha levantado su embargo como parte de los documentos del pontificado de Pío XII.

Authors: Oluseyi Oyerinde David , Abayomi Ojomo David 
Published: July 2023

Aim: The continuous increase in the rate of unemployment among graduates of tertiary institutions in Ekiti State has been a source of worry for the government and the public. Despite the series of courses taken on entrepreneurship during the period of their studies in the institutions, it was observed that many graduates could not establish their enterprises after graduation due to certain reasons. It was against this background that this study investigated the relationship between risk-taking behaviour and entrepreneurial aspiration of undergraduates as well as the difference in the risk-taking behaviour of male and female undergraduates towards entrepreneurship.
Methodology: Descriptive research design of the survey type was adopted for the study. The population of the study was 7342 final-year students in all tertiary institutions in Ekiti State. Simple, stratified and proportional random sampling techniques were used to select 400 students from faculties/schools across the three types of institutions in the state. A self-constructed instrument tagged Risk Taking Behaviour and Entrepreneurial Aspiration Questionnaire (RTBEAQ) was used to collect the data for the study. The instrument was constructed on 4-point Likert scale statements. Three experts ascertained the accuracy of the items on the instrument. The reliability of the instrument was established through Cronbach's alpha after it had been administered to 40 students outside the sample for the study, which yielded a coefficient value of 0.86. The reliability coefficient obtained for the instrument was considered high enough for the study. Data collected were analysed using Pearson's Product Moment Correlation and z-test. All hypotheses formulated were tested at a 0.05 level of significance.
Results: Findings of the study revealed that there was a significant relationship between risk-taking behaviour (mean of 12.83) and entrepreneurial aspiration of undergraduates (mean of 80.92) with a p-value of 0.00, < 0.05. Also, the finding of the study showed that there was a significant difference between risk taking behaviour of male (mean of 241.2) and female (mean of 256.1) undergraduates with p-value of 0.01< 0.0.05).
Recommendation: It was recommended among other that adequate education should be given to undergraduates in tertiary institutions on risk-taking and entrepreneurial aspirations in a bid to prepare them for entrepreneurial activities in future. The quality of entrepreneurship education given across all tertiary institutions should be the same since all entrepreneurs are going to face the same challenges when engaging in entrepreneurial activities.

Published: July 2023

Vitiligo is a common acquired skin depigmentation that affects people of all races, but is significantly more disfiguring in black individuals. The exact cause of vitiligo is unknown. It is believed that an autoimmune process targeting melanocytes mediates its pathogenesis. In accordance with this hypothesis, histopathological examinations of vitiliginous skin have revealed the absence of melanocytes.
Multiple autoantibodies against melanocyte antigens, including various enzymes and other substances, have been detected in the sera of some vitiligo patients. Twenty to thirty percent of patients were reported to have a family history of the disease, suggesting that genetic factors play a role. Despite this, a substantial proportion of vitiligo sufferers have neither a family history of vitiligo nor a history of other autoimmune diseases. As a result, numerous alternative hypotheses have been proposed to explain the underlying causes of this disorder, such as a weak defence against the toxic effects of free radicals and exposure to industrial pollutants.
The most frequently prescribed treatments for vitiligo are systemic and topical phototherapy, immunomodulators such as corticosteroids, calcineurin inhibitors, and vitamin D analogues, as well as cosmetics that can camouflage the condition and improve quality of life. Other forms of treatment include surgical grafting and depigmenting procedures.

The world is attempting to increase water efficiency in all activities, especially in irrigation, which consumes three-fourths of total available water. Concerning the near future food demand and sustainability issues, views are directed to reduce the usage of water or increase the efficiency of water use. India is a major contributor to the agricultural production and food supply to many countries. Irrigated agriculture is being followed by the many farmers in India which consumes huge amounts of water. Considering the monsoon failure and increased water demand, one must find solutions for retaining water in an available manner. The focus is on finding major water-consuming crops and irrigation methods under different irrigation environments of Tamil Nadu. Pudukottai, Salem and Erode are the districts of Tamil Nadu state selected as a study area. In each district, blocks, villages and respondents are selected through multi-stage random sampling. This study is entirely based on primary data which is collected using a well-structured interview schedule. The collected data is used to estimate the Physical Water Productivity (PWP) and Economic Water Productivity (EWP). The results show that PWP and EWP are variable across crops under different irrigation environments. In a tank environment, the alternate drying and wetting method of irrigation in paddy is effective and saves around 39 per cent of water compared to the conventional method by flooding. For Groundnut crops, drip irrigation is more effective than check basins which are better than the flood irrigation method. We can conclude that the farmers should follow water-saving irrigation methods/technologies and cultivate crops that show less demand for water during the season when the water is scarce and turn to cultivation of crops like sugarcane and banana in water surplus season.

The malting parameters of two acha species (Digitaria exilis-white and Digitaria iburua-black), a small annual herbaceous indigenous African cereal grain were studied. This study was aimed at assessing the brewing potential of the two acha species. The research was carried out in Microbiology Laboratory of Nnamdi Azikiwe University, Awka. The brewing properties assessed were; moisture content, cold water extract, hot water extract, diastatic power, total nitrogen, cold water soluble protein, total soluble protein and free amino nitrogen. Extraction, digestion, titration, colorimetric and spectrophotometric methods were used to assess the above brewing properties. The moisture content of the white species malt (11.0 - 12.4%) was higher than that of the black (10.3 – 11.2%) and increased with germination time but decreased after the peak (4th) day. The lower moisture content of the black acha malts gave a resultant effect of more extract production from cold water extract ( CWE 27.5, 30.10%), hot water extract (HWE 278, 304ol/kg) and diastatic power (DP 19 ,23oL) of the two acha malts on the fourth (peak) day of germination. The peak values for total nitrogen (1.6, 1.75%), cold water soluble protein (120, 128%), total soluble protein (6.2, 7.5%) and free amino nitrogen (FAN 105, 114.5%) were also higher for the black acha on the peak day of germination. The correlation studies between the HWE (R2=0.9903, 0.9551), Cold water soluble protein (CWS-P- R2= 0.9809, 0.9285) and Diastatic power for the black and white species, respectively, were positively significant depicting a strong relationship between the correlated parameters. The black acha malt recorded more extract yield than the white acha and the result of the two acha species assessed showed that they possess brewing properties.

Published: July 2023

AbstractFabric‐based triboelectric nanogenerators (TENGs) exhibit superior output performance, flexibility, and wearability. However, the fabric structure often creates gaps that accumulate contaminants, which weaken the performance and durability of the TENGs. To address this challenge, a novel eco‐friendly superhydrophobic fabric‐based TENG (SF‐TENG) woven with superhydrophobic electroconductive bacterial cellulose fiber (SEBC fiber) is presented. To construct durable superhydrophobicity, an ingenious bio‐fabricated method is employed for the shell–core structure. SEBC fibers with bio‐fabricated shell–core structure exhibit excellent electroconductibility, mechanical property, biodegradability, and durable superhydrophobicity. SF‐TENG displays a maximum open‐circuit voltage of 266.0 V, a short‐circuit current of 5.9 µA, and an output power of 489.7 µW, and successfully powers devices such as stopwatch and calculator. Abilities of self‐cleaning and anti‐fouling guarantee the stable output performance of SF‐TENG under harsh environmental conditions such as liquids pouring. Furthermore, the intelligent clothing is designed based on SF‐TENG to detect motion signals, and it is further utilized to construct a Sports and Health Monitoring System as a deep application. In summary, this study provides a novel strategy of bio‐fabrication for the design and preparation of superhydrophobic electroconductive fiber with shell–core structure. The SF‐TENG demonstrates practicability, stability and is promising for wearable devices in harsh environmental conditions.

Published: July 2023

AbstractGallium‐based liquid metal (LM) nanoparticles are among the most promising nanoscale materials for biomedicinal applications because of their outstanding physicochemical properties, including unique flexibility, easy surface modification, excellent photothermal conversion efficiency, and high biocompatibility. Further exploration of the modification and remote‐controlling performances of LM nanoparticles with functional bioactive molecules for the development of an innovative treatment modality for diseases is challenging. Herein, it is reported that near‐infrared (NIR) light‐activatable LM nanoparticle, which functionalized with immunological activators of T and dendritic cells, can work as highly immunogenic and photo‐exothermic nanoscale stimulants for cancer treatment. The synthesized LM nanostimulant, which has low toxicity, powerful photothermal conversion property, and high immunogenic features, can effectively eliminate cancer cells, cancer spheroids, and colorectal tumors in living mice under NIR laser illumination. Moreover, the fluorescent LM nanostimulant can express strong fluorescence as a reporter agent to identify the targeted tumors in living mice for optical cancer diagnosis. Therefore, such a smart nanostimulant represents a way toward combination photothermal immunotheranostics.

AbstractDimensional engineering of appropriate structure is an effective approach to achieve high‐performance electromagnetic (EM) wave absorption for magnetic materials. However, controllable modulation of the material configuration and a comprehensive understanding of the relationship between structure and loss mechanism remain challenging. Herein, magnetic CoNi pentagonal nanopagodas (PNPs) are ingeniously tailored using a competition orientation strategy, in which high‐density PNPs with sharp corners/edges and hierarchical structure are rooted in situ on the surface of CoNi alloy microsphere. This unique configuration of PNPs originates from the orientation growth of CoNi fivefold twins, which can be effectively regulated by manipulating metal ratio and evolves into flake‐, serrated thorn‐, prismoid‐, and blocks‐like morphologies. Optimized CoNi microspheres with high‐density PNPs exhibit a broad absorption bandwidth of 6.82 GHz at only 1.8 mm thickness. Cross‐scale magnetic coupling networks strengthen magnetic loss ability, magnetocrystalline defects induce dielectric polarization enhancement, which are intuitively confirmed by Lorentz off‐axis electron holography and geometric phase analysis. The underlying mechanism of enhanced magnetic interaction in sharp structure is clearly deciphered by micromagnetic simulation. This study provides methodological guidance for dimensional engineering in fabricating hierarchical magnetic structure and significant insights into the morphology‐dependent loss mechanism for magnetic EM absorption materials.

AbstractConventional approaches to developing therapeutic cancer vaccines that primarily activate tumor‐specific T cells via dendritic cells (DCs) often demonstrate limited efficacy due to the suboptimal activation of these T cells. To address this limitation, here a therapeutic cancer nanovaccine is developed that enhances T cell responses by interacting with both DCs and T cells. The nanovaccine is based on a cancer cell membrane nanoparticle (CCM‐MPLA) that utilizes monophosphoryl lipid A (MPLA) as an adjuvant. To allow direct interaction between the nanovaccine and tumor‐specific T cells, anti‐CD28 antibodies (aCD28) are conjugated onto CCM‐MPLA, resulting in CCM–MPLA–aCD28. This nanovaccine activates tumor‐specific CD8+ T cells in both the presence and absence of DCs. Compared with nanovaccines that interact with either DCs (CCM–MPLA) or T cells (CCM–aCD28), CCM–MPLA–aCD28 induces more potent responses of tumor‐specific CD8+ T cells and exhibits a higher antitumor efficacy in tumor‐bearing mice. No differences in T cell activation efficiency and therapeutic efficacy are observed between CCM–MPLA and CCM–aCD28. This approach may lead to the development of effective personalized therapeutic cancer vaccines prepared from autologous cancer cells.

Published: July 2023

AbstractPorous electrodes govern the electrochemical performance and pumping requirements in redox flow batteries, yet conventional carbon‐fiber‐based porous electrodes have not been tailored to sustain the requirements of liquid‐phase electrochemistry. 3D printing is an effective approach to manufacturing deterministic architectures, enabling the tuning of electrochemical performance and pressure drop. In this work, model grid structures are manufactured with stereolithography 3D printing followed by carbonization and tested as flow battery electrode materials. Microscopy, tomography, spectroscopy, fluid dynamics, and electrochemical diagnostics are employed to investigate the resulting electrode properties, mass transport, and pressure drop of ordered lattice structures. The influence of the printing direction, pillar geometry, and flow field type on the cell performance is investigated and mass transfer vs. electrode structure correlations are elucidated. It is found that the printing direction impacts the electrode performance through a change in morphology, resulting in enhanced performance for diagonally printed electrodes. Furthermore, mass transfer rates within the electrode are improved by helical or triangular pillar shapes or by using interdigitated flow field designs. This study shows the potential of stereolithography 3D printing to manufacture customized electrode scaffolds, which could enable multiscale structures with superior electrochemical performance and low pumping losses.
Strong Coupling in Two‐Phase Metamaterials Fabricated by Sequential Self‐Assembly

Published: July 2023

AbstractSelf‐assembly processes provide the means to achieve scalable and versatile metamaterials by “bottom‐up” fabrication. Despite their enormous potential, especially as a platform for energy materials, self‐assembled metamaterials are often limited to single phase systems, and complex multi‐phase metamaterials have scarcely been explored. A new approach based on sequential self‐assembly (SSA) that enables the formation of a two‐phase metamaterial (TPM) composed of a disordered network metamaterial with embedded nanoparticles (NPs) is proposed. Taking advantage of both the high‐spatial and high‐energy resolution of electron energy loss spectroscopy (EELS), inhomogeneous localization of light in the network is observed, concurrent with dipolar and higher‐order localized surface plasmon modes in the nanoparticles. Moreover, it is demonstrated that the coupling strength deviates from the interaction of two classical dipoles when entering the strong coupling regime. The observed energy exchange between two phases in this complex metamaterial, realized solely through self‐assembly, implies the possibility to exploit these disordered systems for plasmon‐enhanced catalysis.
