Evaluation of the influence of arbuscular mycorrhizal and organo-mineral fertilizer on productivity of Okra

The influence of Glomus clarum and organomineral fertilizer on productivity of Okra was studied in a field experiment conducted in National Horticulture Research Institute (NIHORT) Ibadan. The experimental design was randomized complete block design (RCBD). There were seven treatments which were replicated three times. The arbuscular mycorrhiza fungi (AMF) and organomineral fertilizer (OMF) were applied into 6 kg soil at the rate of 5, 10 and 15 g each per plant, while the control had 0 g. The result showed that the yield of plants treated with 5 gAM fungi produced highest cumulative number of harvested fruit (2.17) and harvested weight per fruit (7.71 g/plant) while, plants treated with 10 g OMF and 5 gAM fungi produced higher cumulative harvested fruit number which were not significantly different from each other. The fruit yield of Okra was optimized with 5 gAM fungi.
Phosphorylation of G (cid:1) 11 Protein Contributes to Agonist-Induced Desensitization of 5-HT 2A Receptor Signaling

Agonist treatment causes desensitization of many G protein- coupled receptor systems. Recent advances have delineated changes in receptors in the desensitization response; however, the role of G proteins remains unclear. We investigated the role of phosphorylation of G (cid:1) q/11 proteins in agonist-induced desensitization of serotonin 2A (5-HT 2A ) receptors. In an embryonic rat cortical cell line (A1A1v), 24-h treatment with 100 nM ( (cid:1) )-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane HCl (DOI), a 5-HT 2A/2C receptor agonist, decreased DOI-stim- ulated inositol phosphate accumulation and increased the phosphorylation of G (cid:1) q/11 proteins, as demonstrated by immu- noprecipitation of G (cid:1) q/11 and both incorporation of 32 P phos- phate and labeling with a S/T/Y phosphorylation-dependent antibody. Treatment with DOI for 30 min induced desensitiza- tion but did not increase phosphorylation of G (cid:1) q/11 proteins, suggesting that different mechanisms are involved in desensi- tization after short- and long-term treatments. Mutation of S154A in a protein kinase C (PKC) and calcium/calmodulin dependent kinase (CaMK) consensus site in G (cid:1) 11 significantly reduced DOI-stimulated phosphorylation of G (cid:1) 11 and DOI-in- duced desensitization of 5-HT 2A receptor signaling. Inhibition of PKC and CaMK attenuated phosphorylation of G (cid:1) q/11 pro- teins and DOI-induced desensitization of 5-HT 2A receptors. Expression of G (cid:1) 11 S154D, a phosphorylation mimic, reduced DOI-stimulated inositol phosphate accumulation. DOI treatment for 24 h also produced heterologous desensitization, as indicated by decreased bradykinin-stimulated inositol phosphate accumulation. These data suggest that phosphorylation of G (cid:1) 11 protein by PKC and CaMK contributes to agonist- induced homologous desensitization of 5-HT 2A receptor signaling as well as heterologous desensitization. The phosphoryla- tion of G (cid:1) protein represents a novel mechanism involved in regulation of receptor signaling and agonist-induced desensi- tization of G protein-coupled receptors.
Recent Advances in Drug Discovery for Triple-Negative Breast Cancer Treatment

Triple-negative breast cancer (TNBC) is one of the most heterogeneous and aggressive breast cancer subtypes with a high risk of death on recurrence. To date, TNBC is very difficult to treat due to the lack of an effective targeted therapy. However, recent advances in the molecular characterization of TNBC are encouraging the development of novel drugs and therapeutic combinations for its therapeutic management. In the present review, we will provide an overview of the currently available standard therapies and new emerging therapeutic strategies against TNBC, highlighting the promises that newly developed small molecules, repositioned drugs, and combination therapies have of improving treatment efficacy against these tumors.
Psychological empowerment and job performance of star-rated hotels: The mediating role of emotional intelligence

Abstract This paper examined the mediating role of emotional intelligence in the relationship between psychological empowerment and job performance. The quantitative approach was employed using a survey research design with a sample of 289 respondents from the star-rated hotels in the Central Region, Ghana. The explanatory research design was adopted to explain the relationships among psychological empowerment, emotional intelligence and job performance through the testing of hypotheses. PLS-SEM was used to test these hypotheses. It was found that psychological empowerment had a positive significant relationship with job performance in star-rated hotels. Furthermore, psychological empowerment had a positive relationship with emotional intelligence. Also, emotional intelligence had a positive significant relationship with job performance. Additionally, it was identified that emotional intelligence partially mediates the relationship between psychological empowerment and job performance. From the results, management of star-rated hotels should pay critical attention to employees’ psychological empowerment as a job resource since it improves emotional intelligence and enhance job performance.
ALTERAÇÕES NA DENSIDADE E NA MACROPOROSIDADE DE UM LATOSSOLO VERMELHO-ESCURO CAUSADAS PELO SISTEMA DE PREPARO DO SOLO

The study was conducted at the Embrapa Arroz e Feijao, Goiânia-Goias, Brazil, in a clayey dark red latosol, for four consecutive years (1992-1996). During this period eight soil preparation operations were conducted. The objective of the study was to evaluate the effect of systems of soil preparation on density and macroporosity of soil. The experiment was conducted in a completely randomized design with split plots. Soil preparation systems were: moldboard plough/harrow disc; moldboard plough; harrow disc and no-tillage. Soil was prepared by moldboard plough at 30 cm depth and by harrow disc at 15 cm depth. Soil density was determined by cylinder volume method and macroporosity by table tension method. Harrow disc reduced soil density in the upper layer (0-10 cm) and moldboard plough in the deeper layer (10-20, 20-30 cm). No-tillage increased soil density in the upper layer, whereas macroporosity reduced with increasing soil density. KEY-WORDS: Harrow disc; no-tillage; moldboard plough; physical characteristics of soil.
Food webs of Mediterranean coastal wetlands

En aquesta tesi doctoral s'han estudiat els efectes directes i indirectes de dos tipus d'especies claus de la comunitat aquatica dels aiguamolls de l'Emporda (aiguamolls costaners mediterranis amb una xarxa trofica senzilla). S'han realitzat experiments al camp utilitzant microcosmos i mesocosmos i els resultats han estat analitzats mitjancant tres aproximacions: la taxonomica, la funcional i la de mides. S'ha comprovat que en situacions amb absencia de predadors i dominancia d'una unica especie en el zooplancton (en aquest cas Calanipeda aquaedulcis i Daphnia magna), la segregacio del recurs entre els diferents estadis de desenvolupament de la mateixa especie zooplanctonica es una estrategia per evitar la competencia intraespecifica en condicions de limitacio de recurs. Per altra banda, la presencia de diferents top-predators a la comunitat aquatica (en aquest cas la medusa Odessia maeotica i el peix Aphanius iberus) desencadena una cascada trofica en el plancton pero amb efectes top-down diferents segons el top-predator.
Mass density at geostationary orbit and apparent mass refilling

We used the inferred equatorial mass density ρm,eq based on measurements of Alfvén wave frequencies measured by the GOES satellites during 1980–1991 in order to construct a number of different models of varying complexity for the equatorial mass density at geostationary orbit. The most complicated models are able to account for 66% of the variance with a typical variation from actual values of a factor of 1.56. The factors that influenced ρm,eq in the models were, in order of decreasing importance, the F10.7 EUV index, magnetic local time, the solar wind dynamic pressure Pdyn, the phase of the year, and the solar wind BZ (GSM Z direction). During some intervals, some of which were especially geomagnetically quiet, ρm,eq rose to values that were significantly higher than those predicted by our models. For 10 especially quiet intervals, we examined long‐term (>1 day) apparent refilling, the increase in ρm,eq at a fixed location. We found that the behavior of ρm,eq varies for different events. In some cases, there is significant apparent refilling, whereas in other cases ρm,eq stays the same or even decreases slightly. Nevertheless, we showed that on average, ρm,eq increases exponentially during quiet intervals. There is variation of apparent refilling with respect to the phase of the solar cycle. On the third day of apparent refilling, ρm,eq has on average a similar value at solar maximum or solar minimum, but at solar maximum, ρm,eq begins with a larger value and rises relatively less than at solar minimum.

The associa-tion between the variables and the outcome wasevaluated through prevalence ratios, 95% confi-dence intervals, and chi-square. Logistic regres-sion was performed according to a hierarchicalmodel. Some 97 children (15%) were living innegative environments. Eight risk factors wereassociated with environmental quality: lowmonthly family income, low maternal school-ing, male gender, households with more than 7members, 4 or more siblings, tobacco use duringgestation, children sleeping in their parents’ bedat age 4 years, and mothers with psychiatric dis-orders.Environmental Quality; Risk Factors; Child De-velopment; Educational Status
Positive impact of urbanization on vegetation growth has been continuously strengthening in arid regions of China

The ecological environment is fragile in arid regions, and the direct and indirect impacts of continuing urbanization on vegetation growth in cities still need to be studied in depth. In this study, we focused on four provincial capital cities (Urumqi, Lanzhou, Yinchuan, and Hohhot) in arid regions of China. We used continuous 30 m land cover and vegetation greenness (VG) data from 1990 to 2021 to extract the impact of urbanization on vegetation growth by separating the impact of natural conditions. Our results showed that the study area’s urban area (UA) had expanded rapidly at a rate of 39.2 km2/a, increasing by 3.39 times between 1990 and 2021. While urban expansion occurred rapidly, the overall VG of the study area also increased (slope = 2.16 × 10−3), with the enhancement of VG increasing gradually from west to east. The VG and its trend in the UA were significantly higher than those in the natural vegetation area (NA). In addition, the duration of the urban vegetation growth season was longer than that of the NA, which also confirmed the positive impact of urbanization on the vegetation growth period. Furthermore, we found that the positive impact of urbanization on vegetation had continuously strengthened over time. In 1990 and 2021, the VG areas had 83% and 87% above the ‘zero-impact line’ in the UA, respectively, indicating a very significant impact of urbanization on vegetation growth in arid regions with fragile natural conditions. Our study identified the long-term dynamic trends in urbanization and VG in arid regions and clarified the non-linear relationship between the two concurrent growth factors. This has significant implications for correctly understanding the impact of urbanization on vegetation in arid regions and can provide a scientific reference for the ecological construction of urban environments in the region.
A Rivest–Shamir–Adleman-Based Robust and Effective Three-Factor User Authentication Protocol for Healthcare Use in Wireless Body Area Networks

In healthcare, wireless body area networks (WBANs) can be used to constantly collect patient body data and assist in real-time medical services for patients from physicians. In such security- and privacy-critical systems, the user authentication mechanism can be fundamentally expected to prevent illegal access and privacy leakage occurrences issued by hacker intrusion. Currently, a significant quantity of new WBAN-oriented authentication protocols have been designed to verify user identity and ensure that body data are accessed only with a session key. However, those newly published protocols still unavoidably affect session key security and user privacy due to the lack of forward secrecy, mutual authentication, user anonymity, etc. To solve this problem, this paper designs a robust user authentication protocol. By checking the integrity of the message sent by the other party, the communication entity verifies the other party’s identity validity. Compared with existing protocols, the presented protocol enhances security and privacy while maintaining the efficiency of computation.
Sedimentation in the lakes and marshes (Ahwar) of the Tigris-Euphrates Delta, southern Mesopotamia

The fluvial plains of lower Mesopotamia crossed by the Tigris and Euphrates rivers are occupied by fresh-brackish water lakes and extensive reed-marshes dominated by Phragmites sp. and Typha sp. (together locally called Ahwar). Allochthonous sediment is mostly supplied by the Tigris and Euphrates seasonal floodwaters, and by winds which bring aeolian dust from the north-west and sand during storms from the western deserts in summer. Other contributions to the sediment budget are made by in situ biological activity and by biochemical-chemical processes within the sediments. The sediments are dominantly silts, with silt comprising more than 60% of the sediment. The remainder of the sediment consists of varying quantities of clay and sand. Clay is more abundant in the lower parts of most of the analysed cores (30–80 cm in length), indicating a change in sediment supply and/or sedimentary environment. Well developed stratification is found only on the river levees and in some clay-rich lake and marsh sediments. The remainder of the sediments are generally poorly stratified with irregular stratification and considerable bioturbation. Mineralogically, the sediments consist mainly of calcite, quartz, dolomite and feldspar (particularly albite). Aragonite is present as a result of in situ production by macrofauna. The clay fraction (<2 μn) consists of smectite, illite-smectite, illite, palygorskite, kaolinite and chlorite. The total organic carbon (TOC) content is usually <5% except for some peaty surface layers of the freshwater lakes and marshes where TOC may rise to 10–20%. The sediments have a relatively high calcium carbonate content. 20–80%, the highest values only being found in mollusc-rich horizons. The sediments contain high amounts of Ca, Mg and Sr and are generally low in Al, Ti. K. and V. Values for Fe, Co, Pb, Zn and Mn are close to the average for mudstones, whereas Cu and P are relatively low. The high Ni and Cr contents of the sediments are related to high contents in the source material of the major rivers and aeolian deposits. Multivariate statistical analysis shows that elemental components of surface and source materials correlate well with other sedimentary properties. Aragonitic molluscs of various species dominate the macrofauna, but a microfauna of foraminifers, ostracods and diatoms is also present in the sediments.
Enhancing English Learning: Self-Determination in Indonesia Digital Classrooms

This study explored the experiences of students with technology-integrated English language instruction at two Indonesian universities, Universitas Borneo Tarakan (UBT) and Universitas Sawerigading Makassar (UNSA). The primary aim was to understand the influence of perceived autonomy, competence, relatedness, and motivation levels on English language learning outcomes. Utilizing a mixed-methods approach that combined survey data and thematic analysis of interviews, we found that students generally reported high levels of these factors. Minor differences were observed between UBT and UNSA in terms of perceived autonomy and competence-relatedness. Positive correlations were identified between these factors and improved performance in English language learning; for example, autonomy positively correlated with English learning outcomes (r = 0.60*), as did competence (r = 0.65*), relatedness (r = 0.62*), and motivation levels (r = 0.70*). These findings highlight the importance of fostering learners' sense of autonomy, competence building, and relatedness in technology-enhanced instruction settings to promote intrinsic motivation according to Self-Determination Theory (SDT). Further research is recommended to explore other potential influencing factors such as individual attitudes towards technology or external factors like teaching quality or course design.
Eco‐meteorological characteristics of the southern slopes of Kilimanjaro, Tanzania

This study introduces the set‐up of a new meteorological station network on the southern slopes of Kilimanjaro, Tanzania, since 2010 and presents the recorded characteristics of air temperature, air humidity and precipitation in both a plot‐based and area‐wide perspectives. The station set‐up follows a hierarchical approach covering an elevational as well as a land‐use disturbance gradient. It consists of 52 basic stations measuring ambient air temperature and above‐ground air humidity and 11 precipitation measurement sites, with recording intervals of 5 min. With respect to precipitation observations, the network extends the long‐term recordings of A. Hemp who has installed and maintained up to 117 multi‐month accumulating rainfall buckets in the region since 1997. The meteorological characteristics of the study region based on the derived data since 2010 are mostly in line with previous studies, although we see increased precipitation amounts at higher elevations during these years when compared with long‐term means. We furthermore identify a mean annual condensation level at about 2300 m a.s. l. which has not been reported before. Finally, this is the first study to provide high resolution maps of mean monthly and mean annual temperature, humidity and precipitation for Kilimanjaro, which are of great value for geographically oriented meteorological or ecological investigations. Detailed performance statistics of the geo‐statistical and machine learning techniques used for the gap filling of the recorded meteorological time series and their regionalization to the Kilimanjaro region indicate that the presented data sets provide reliable measurements of the meteorological reality at Kilimanjaro.
Global Cooling‐Driven Summer Monsoon Weakening in South China Across the Eocene‐Oligocene Transition

Recent research has suggested that East Asia has experienced a prevailing monsoon climate since the Eocene. However, there is little knowledge about the development of the East Asian monsoon system before the Miocene, particularly in southern China, due to a lack of well‐dated continuous sediment records. Here, we present new magnetic proxy records from International Ocean Discovery Program Site U1501 in the northern South China Sea. We conducted rock magnetic experiments, made scanning electron microscopy observations and performed diffuse reflectance spectrum analysis on the late Eocene‐early Oligocene core sediments. The magnetic signal of the sediments is dominated by detrital magnetite and titanomagnetite formed during the silicate weathering and erosion processes, which were used to infer the evolution of summer monsoon precipitation in southern China. Our results along with geochemical and clay mineral data from Site U1501 strongly indicate that the East Asian summer monsoon generally weakened across the Eocene‐Oligocene transition. This change was linked to coeval global cooling rather than tectonic processes. Prior to the Eocene‐Oligocene transition, the summer monsoon intensified, likely due to the latest Eocene warming event caused by the enhancement of the Atlantic Meridional Overturning Circulation, which may have preconditioned the Earth system for the greenhouse‐to‐icehouse transition.
Board Size, Board Composition and Voluntary Disclosure: Evidence from Listed Manufacturing Firms in Nigeria

This study investigated the influence of board size and board composition on voluntary disclosure of quoted manufacturing firms in Nigeria from the period of 2015 to 2019. Thirty- three (33) were purposively selected for the purpose of this study. Information was produced from content analysis of yearly reports. Panel fixed effect model, correlation matrix and descriptive statistics were employed in the estimation. The estimation of the fixed effect model shows that size of the board and board composition have positive and significant connection on the level of voluntary disclosure evidenced by t-statistics = 10.524, p-value of 0.000 and 10.466, p-value is 0.000 respectively. However, the study concludes that board size and the composition of the board can affect the extent of voluntary disclosure positively. The study therefore recommends that the board should comprises of well experience, skilled, knowledgeable people who can govern the firm well. The firms should also guarantee that the number of experienced people in the board should be sufficient enough be able to provide the firm with more oversight.
Diagnostic Performance of an Artificial Intelligence Model Based on Contrast-Enhanced Ultrasound in Patients with Liver Lesions: A Comparative Study with Clinicians

Contrast-enhanced ultrasound (CEUS) is widely used in the characterization of liver tumors; however, the evaluation of perfusion patterns using CEUS has a subjective character. This study aims to evaluate the accuracy of an automated method based on CEUS for classifying liver lesions and to compare its performance with that of two experienced clinicians. The system used for automatic classification is based on artificial intelligence (AI) algorithms. For an interpretation close to the clinical setting, both clinicians knew which patients were at high risk for hepatocellular carcinoma (HCC), but only one was aware of all the clinical data. In total, 49 patients with 59 liver tumors were included. For the benign and malignant classification, the AI model outperformed both clinicians in terms of specificity (100% vs. 93.33%); still, the sensitivity was lower (74% vs. 93.18% vs. 90.91%). In the second stage of multiclass diagnosis, the automatic model achieved a diagnostic accuracy of 69.93% for HCC and 89.15% for liver metastases. Readers demonstrated greater diagnostic accuracy for HCC (83.05% and 79.66%) and liver metastases (94.92% and 96.61%) compared to the AI system; however, both were experienced sonographers. The AI model could potentially assist and guide less-experienced clinicians to discriminate malignant from benign liver tumors with high accuracy and specificity.
