POLYPHENOL QUANTIFICATION ON DIPSACUS LACINIATUS AND ARMORACIA RUSTICANA FROM ROMANIAN FLORA

In recent years, the polyphenolic compounds profile of plants has been intensively studied. These compounds protect the body against oxidative stress and certain diseases such as diabetes and cancer, where the antioxidant efficiency of the defence system is low. The plant material (harvested from Romania) was analysed for polyphenols and flavonoids using thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC) coupled with photo diode array and mass spectrometer. The polyphenols/flavonoids (caffeic acid, chlorogenic acid, p -coumaric acid, protocatechuic acid, rutin and quercetin) were identified and quantified in different part of the plants (flower, leaf, stem and roots for Dipsacus laciniatus and both roots and leaves for Armoracia rusticana ). The least amount of polyphenols were found to be as expected in the root part of Dipsacus laciniatus. This was also sustained by the further UHPLC-MS analysis. The results revealed that the flower extract has the highest radical scavenging activity with 87.43% followed by the leaf extract with 86.63%, the stem extract with 83.54% and the root extract with 78.17%. Higher concentrations of p-Coumaric acid and ferulic acid were identified in the Armoracia rusticana samples whereas the Dipsacus laciniatus samples contained higher concentrations of both protocatechuic acid and chlorogenic acid. The results of the present study revealed that the methanolic extracts of both Dipsacus laciniatus and Armoracia rusticana , can be considered an effective source of antioxidant compounds.
Simultaneous Catechol and Hydroquinone Detection with Laser Fabricated MOF-Derived Cu-CuO@C Composite Electrochemical Sensor

The conversion of metal-organic frameworks (MOFs) into advanced functional materials offers a promising route for producing unique nanomaterials. MOF-derived systems have the potential to overcome the drawbacks of MOFs, such as low electrical conductivity and poor structural stability, which have hindered their real-world applications in certain cases. In this study, laser scribing was used for pyrolysis of a Cu-based MOF ([Cu4{1,4-C6H4(COO)2}3(4,4′-bipy)2]n) to synthesize a Cu-CuO@C composite on the surface of a screen-printed electrode (SPE). Scanning electron microscopy, X-ray diffractometry, and Energy-dispersive X-ray spectroscopy were used for the investigation of the morphology and composition of the fabricated electrodes. The electrochemical properties of Cu-CuO@C/SPE were studied by cyclic voltammetry and differential pulse voltammetry. The proposed flexible electrochemical Cu-CuO@C/SPE sensor for the simultaneous detection of hydroquinone and catechol exhibited good sensitivity, broad linear range (1–500 μM), and low limits of detection (0.39 μM for HQ and 0.056 μM for CT).

This research is to investigate the relationship between personality and academic procrastination amongst undergraduate students in selected private Universities in Kuala Lumpur. In this research, the sample consisted of 150 undergraduate students from selected private universities in Kuala Lumpur, 106 female students and 44 male students. The first result for this present research showed that there is a significant relationship between personality and academic procrastination as three of the five personality domains are found to have a significant relationship with academic procrastination at 0.05 and 0.01 level of significance. The second result showed that there is a moderate significant negative relationship between conscientiousness and academic procrastination, r = . 402, p < . 01. The third result showed that there is a weak significant positive relationship between neuroticism and academic procrastination, r = . 244, p < . 01. The fourth result showed that there is a weak significant negative relationship between agreeableness and academic procrastination, r = -. 161, p < . 05. The fifth result showed that there was a nonsignificant correlation of . 030 (p = n.s.) between openness to experience and academic procrastination. The sixth result showed that there was a nonsignificant correlation of -. 098 (p = n.s.) between extraversion and academic procrastination. The recommendations for future researchers are also suggested in this research which included the conduct of this research in different countries with respondents from different backgrounds.
The Effects of Different Soil Component Couplings on the Methylation and Bioavailability of Mercury in Soil

Soil composition can influence the chemical forms and bioavailability of soil mercury (Hg). However, previous studies have predominantly focused on the influence of individual components on the biogeochemical behavior of soil Hg, while the influence of various component interactions among several individual factors remain unclear. In this study, artificial soil was prepared by precisely regulating its components, and a controlled potted experiment was conducted to investigate the influence of various organic and inorganic constituents, as well as different soil textures resulting from their coupling, on soil Hg methylation and its bioavailability. Our findings show that inorganic components in the soils primarily exhibit adsorption and fixation effects on Hg, thereby reducing the accumulation of total mercury (THg) and methylmercury (MeHg) in plants. It is noteworthy that iron sulfide simultaneously resulted in an increase in soil MeHg concentration (277%). Concentrations of THg and MeHg in soil with peat were lower in rice but greater in spinach. A correlation analysis indicated that the size of soil particles was a crucial factor affecting the accumulation of Hg in plants. Consequently, even though fulvic acid activated soil Hg, it significantly increased the proportion of soil particles smaller than 100.8 μm, thus inhibiting the accumulation of Hg in plants, particularly reducing the concentration of THg (93%) and MeHg (85%) in water spinach. These results demonstrate that the interaction of organic and inorganic components can influence the biogeochemical behavior of soil Hg not only through their chemical properties, but also by altering the soil texture.
Late Mesozoic Tectono-Magmatic Evolution History of the Jiaobei Uplift,Shandong Peninsula

Late Mesozoic kinematics history of the two major fault zones (the Zhaoyuan-Pingdu and the Muping-Jimo ones)in the Jiaobei uplift has been studied based on field observations,fault kinematics analysis and paleostress inversion.ombined with 40Ar-39Ar, SHRIMP and LA-ICPMS zircon U-Pb isotopic dating of volcanic and granitic rocks from this area, timing of main tectono-magmatic events and transformation of the tectonic stress regimes have been determined. The results show that the Jiaobei uplift experienced the transformation of tectonic stress regime from Late Jurassic compression to Early Cretaceous extension.Late Jurassic NW-SE compression resulted in thickening of the crust and emplacement of crustal-derived S-type granites;their intrusive ages indicate two tectonic-thermal events:one occurring in 160～150 Ma,and the other in 147～142 Ma.The Jiaobei uplift is characterized by an NNE fault zone with low-angle reverse thrusting and left-lateral strike-slip faulting . During the Early Cretaceous,tectonic stress regime was dominated by an NW-SE to NWW-SEE extension.This extension not only caused the formation of the Jiaolai basin,but also triggered eruption of I-A type granite in 135～106 Ma and intermediate to acid volcanic rocks.40Ar-39Ar analysis for hornblend and SHRIMP U-Pb dating for zircon collected from the intercalated basaltic volcanic rock, which was found in the lower Lianyang Formation of Early Cretaceous, indicate that the Early Cretaceous tectonic stress extension initiated at ca. 130 Ma. At the last, the study discusses the regional geodynamic settings in which tectonic regime transformed from compression to extension during the Middle to Late Mesozoic.
Combinatorial Discrete Choice: A Quantitative Model of Multinational Location Decisions

We introduce a general quantifiable framework to study the plant location decisions of multinational firms. Firms face fixed costs to set up plants in each potential production location and a general variable elasticity demand function. The firm’s plant choice problem is combinatorial because the return on each plant depends on which other plants it also operates. A new computational method to solve such combinatorial discrete choice problems and aggregate optimal solutions across heterogeneous firms is at the core of our analysis. We use a calibrated version of the model to study the exit decision of Britain from the European Union (EU) and recent sanctions on Russia on multinational activity. Multinationals’ plant reallocations across countries and geography are central in shaping economic effects in both counterfactuals.
The Effect of Burnout on the Performance of Nurses at Aliyah I Hospital in Kendari City in 2023

Performance is the work of an employee qualitatively and quantitatively in carrying out his duties in accordance with the obligations imposed on him. The purpose of this study was to see how burnout affects the performance of employees at RSU Aliyah I Kendari City in 2023. Using complete sampling, the population consists of 42 permanent nurses. Data collection methods include observation, interviews, and distributing questionnaires. Chisquare is the analytical approach used. Based on the research findings, 11 (68.3%) of the 16 respondents who experienced burnout in the low group performed well in the good category. Furthermore, 17 (65.4%) of the 26 respondents in the high burnout category were satisfied with patient satisfaction. On the other hand, the value of ρ<1. We get α = 0.031 < 0.05 and Ho is discarded. Therefore, at Aliyah I General Hospital in Kendari City in 2023, burnout can be interpreted as affecting nurse performance. Efforts to improve performance must pay attention to the comfort of nurses' work, need to pay attention to the skills and workload of nurses, and foster a sense of responsibility.
Land Reform in Japan

The land reform carried out in Japan during the period of American Occupation is often spoken of as one of the most successful of the post-war reforms. It was certainly one of the most thorough going redistributions of land which the world has seen. A third of the total area of arable land changed hands, and nearly a third of the total population of the country was affected. Socially, the land reform accelerated the decay in feudal institutions, rendering the lot of the Japanese farmer considerably better than it once was. First published in 1984, this title is part of the Bloomsbury Academic Collections series.
Facial Expression Recognition as markers of Depression

With research done to determine depression with different types of inputs, such as text, images, and mobile sensing, numerous distinct approaches have been devised and enhanced for identifying depression across diverse backgrounds. However, there is a significant lack of research in making use of only facial expressions to detect depression. Introducing such methods could be beneficial due to the large amount of research done to develop models capable of performing facial expression recognition. This project aims to utilize pre-existing facial expression models to determine depression based on the expression recognition capabilities, and to also determine the reliability and effectiveness of using only facial expression to detect depression. We have chosen to use EfficientNet, a state-ofthe-art facial expression recognition model, to experiment with the different facial expressions that are shown based on images of clinically proven to be depressed patients. The findings from our work can further improve depression detection research, specifically focusing on making use of only information from shoulder up of patients, while also helping the community to improve mental health.
Chemical fertilizer reduction combined with organic fertilizer affects the soil microbial community and diversity and yield of cotton

Introduction The soil microbial community plays an important role in modulating cotton soil fertility. However, the effects of chemical fertilizer combined with organic fertilizer on soil chemical properties, microbial community structure, and crop yield and quality in arid areas are still unclear. This study aimed to explore the effects of different organic fertilizers on soil microbial community structure and diversity and cotton growth and yield. Methods High-throughput sequencing was used to study the soil bacteria and fungi in different growth stages of cotton. The field fertilization experiment had five treatments. Results The results indicated that the treatments of chemical fertilizer reduction combined with organic fertilizer significantly increased soil available nitrogen and phosphorus in cotton field. There were significant differences in the abundance of the bacterial and fungal communities in the dominant phyla among the treatments. At the phyla level, there were not significantly different in the diversity of bacteria and fungi among treatments. There were significant differences in the composition and diversity of bacterial and fungal communities during the entire cotton growth period (p = 0.001). The rhizosphere bacterial and fungal community structure was significantly affected by soil TK, NH4+, AK, TP, AN, and NO3−. The different fertilization treatments strongly influenced the modular structure of the soil bacterial and fungal community co-occurrence network. A reduction in chemical fertilizer combined with organic fertilizer significantly improved cotton stem diameter and seed yield, and the effect of the biological organic fertilizer on plant growth and yield formation was greater than that of ordinary organic fertilizer. Discussion This study provide a scientific and technical basis for the establishment of environmentally friendly green fertilization technology for cotton in arid areas and the promotion of sustainable development of cotton industry.
Analysis of Farm Data License Agreements: Do Data Agreements Adequately Reflect on Farm Data Practices and Farmers’ Data Rights?

Farm data license agreements are legal documents that play an important role in informing farmers about farm data processing practices such as collection, use, safeguarding, and sharing. These legal documents govern the exchange, access, and dissemination of farm data and are expected to provide legal protection against misuse of data. Despite their significant influence on farm data processing and governance, there is limited understanding of the content of farm data license agreements and standards for drafting them. Although online privacy policy content has been extensively studied, farm data agreements’ evaluation and analysis have been overlooked. This study aims to investigate the structure, content, and transparency of farm data licenses. We collected 141 agricultural terms of use agreements and used natural language processing methods such as keyword and keyphrase analysis to perform text feature analysis, Flesch Readability Ease Score and Flesch Grade Level readability analysis, transparency analysis, and content analysis to gain insight into common data practices adopted by the agriculture technology providers. We also manually reviewed these agreements to validate the results and strengthen the observations. The findings show that data agreements are long, complex, and difficult to read and comprehend. The results suggest that 95% of the agreements fall under the difficult-to-read category and close to 75% of the policies require university-level education to understand the content. Furthermore, it is noted that some of the data management practices are not given adequate attention and are not as frequently mentioned in the agreements as expected. Finally, our analysis enabled us to provide recommendations on the content of farm data license agreements and strategies to improve them.
Study on ~(137)Cs and ~(210)Pb Dating and Sedimentation Rates of Wanghu Lake,Hubei Province

A sediment core was collected from the centre of Wanghu Lake in Yangxin,Hubei province.Environmental 137Cs and 210Pb dating techniques were applied to determine recent sedimentation rates.The results showed the recent sedimentation rate of the sediment by the 210Pb intensity and CIC model was 0.56 cm·a-1 while it determined by 137Cs were 0.594 cm·a-1 and 0.557 cm·a-1,respectively.The sedimentation rate was in agreement with the results of both methods.Base on the 210Pb intensity and CRS model,time-depth correlation was established.It showed that three periods with sedimentation rate during the last century.A lower average sedimentation rate was about 0.2 cm·a-1 before 1950,and it was increasing from 1950 to the mid-1980s,about 0.4 cm·a-1,and after the mid-1980s the higher average sedimentation rate led to 0.6 cm·a-1.The variations of sedimentation rate were in connection with flood of the Yangtze River and the Fushui River,as well as the intensity of human activities on the catchment.
The Status of Coral Reefs in the Remote Region of Andavadoaka, Southwest Madagascar

Three reef systems (fringing, barrier and patch reefs) were surveyed in the region of Andavadoaka, southwest Madagascar. Patch reefs had the highest coral cover and highest density of coral recruits (~45% and 1.8 m -2 recruits), followed by barrier reefs (~12% and 1.3 m -2 recruits) and fringing reefs (~8% and 0.8 m -2 recruits). Sea urchin assemblages varied greatly between reef systems, with fringing reefs being dominated by Echinothrix sp. , barrier reefs by the rock-boring sea urchin Echinostrephus molaris and patch reefs by Diadema sp. On all reef types, algae grazing sea urchin densities were six times lower then on overfished reefs elsewhere. The density of commercial invertebrates (e.g., sea cucumbers) did not differ significantly between the relatively unexploited patch reefs versus barrier and fringing reefs, which suggests that these are not yet over-fished in the region. Coral reef fish assemblages were significantly different on each reef system. Reef fish densities were high on both patch and barrier reefs (~170 per 100 m 2 ) compared to fringing reefs (~90 per 100 m 2 ). These reefs are not directly threatened by terrigenous sedimentation, which is considered to be one of the principle causes of reef degradation elsewhere in southwest Madagascar's extensive reef system; instead, it is over-fishing that appears to be the main threat to their existence.
Staff turnover and organizational performance: The case of a microfinance organization

Abstract Aim/purpose – This study examines the relationship between staff turnover and performance in the microfinance industry in a dynamic perspective and investigates some contingency factors that moderate this relationship. Design/methodology/approach – We ran random-effects and GMM models based on a database of 2,814 branch-month observations from a specific microfinance organization. Findings – It takes three months to see a significant negative impact of turnover on the volume of a branch’s loan portfolio. Moreover, it takes four months after the turnover event for this negative impact to be counterbalanced. After four months, turnover stops having negative consequences and even becomes advantageous in terms of loan portfolio growth, but this positive effect lasts only one month. The effect of turnover thus appears to be particularly limited in time. Finally, we find that the negative relationship between turnover rate and performance is weakened by the seniority level of departing loan officers and by the recruitment rate. Originality/value/contribution – First, this paper examines the duration of the consequences of turnover event, which is poorly studied in the literature. Second, it focuses on microfinance, an industry where relational capital is of high importance. Third, it extends the theory on turnover by highlighting that the seniority level of departing employees is a moderator in the relationship between turnover and organizational performance.
Impact of COVID-19 on cataract surgical competency of ophthalmology residents

Context: Coronavirus disease 2019 (COVID-19) pandemic led to a decrease in elective surgeries. Purpose: To compare the performance of postgraduate year 4 prepandemic (2018–2019) and pandemic (2021–2022) ophthalmology residents. Settings and Design: This was an observational comparative study conducted at a university-based hospital. Methods: Ophthalmology residents of postgraduate year 4 during prepandemic (2018–2019) and pandemic (2021–2022) time periods were included. The performances of residents in phacoemulsification were scored by a single faculty assessor using the International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric for phacoemulsification (ICO-OSCAR: phaco). The scores were compared between the two groups. Statistical Analysis Used: The comparisons between the pre- and post-pandemic groups were performed using the Chi-square and Mann–Whitney U test. Results: Seventy-one surgeries were rated in each group. All task-specific and global scores of the pandemic group were lower than those of the prepandemic group (all P values < 0.001). The maximum intergroup difference was in capsulorrhexis circular completion (difference of 1.21 score, P < 0.001) and tissue handling (difference of 1.21 score, P < 0.001) among task-specific and global scores, respectively. The residents of the two groups had the highest similarity in irrigation and aspiration (difference of 0.61 score, P < 0.001) from task-specific scores and central eye position from global scores (difference of 0.93 score, P < 0.001). Conclusion: The COVID-19 pandemic has negatively affected the surgical competency of ophthalmology residents in phacoemulsification.
The role of river flow dynamics and food availability in structuring hyporheic microcrustacean assemblages: a reach scale study

The influence of river flow dynamics on the functioning and structure of microcrustacean assemblages (Copepoda, Cladocera, Ostracoda) in the shallow (SHz) and deep (DHz) hyporheic zone were studied in a Sava River (Slovenia) gravel bar over a 3 year period. Temperature, conductivity, dissolved oxygen concentrations, po- tential food resources (nitrates, dissolved organic carbon - DOC, particulate organic matter - POM, and electron transport system activity of biofilm - ETSA) were measured in the deep hyporheic zone (DHz, 210 - 240 cm, n = 39) on six sampling occasions (2007- 2010) and in the shallow hyporheic zone (SHz, 30 - 200 cm, n = 10) during the first two sampling dates. Microcrustaceans were collected using the Bou-Rouch pumping method. The physical and chemical properties of the deep hyporheic water, such as conductivity, pH, SO4 and POM varied significantly over time and distance from the river. Less variability was observed in ETSA. Altogether 28 microcrustacean species were recorded within the two distinct habitat types (SHz and DHz). In the latter, mainly stygobiotic species oc- curred, with Acanthocyclops venustus (Norman and T. Scott, 1906) being the most frequent and abundant. During periods of low flow, patchiness of physical and chemical properties and microcrustacean assemblages increased in comparison to periods of moderate or high flow. Similarly, the patchiness was high after severe flooding with extensive sediment movements and increased clogging of interstitial spaces by fine sediments. Fine sediments and nitrates had the strongest influence on assemblage composition. The study demonstrated a strong connection between river flow dynamics, hyporheic processes and distribution of microcrustaceans, spatially and temporally .
