Work Ability Index and Work Ability Score: A Comparation between both Scores in a Persistent COVID-19 Cohort

Aims: The present study aims to compare the assessment of work ability based on the use of the Work Ability Index (WAI) with another questionnaire base only on the use of WAI’s first item, termed as the “Work Ability Score” (WAS). Study design: A cohort of 384 Spanish workers included in a Post COVID-19 condition or persistent COVID-19 multicenter research was utilized. Place and Duration of Study: This cohort was enlisted in four hospitals (Hospital Universitario 12 de Octubre, Madrid;Hospital Universitario Virgen Macarena, Sevilla, Andalucía;Hospital Universitario Gregorio Marañón, Madrid and Complejo Asistencial Universitario de Salamanca, Castilla y León), since 2021 until 2022. Methodology: 384 Spanish workers (176 men and 208 women;aged 20 to 70 years) with Post COVID-19 condition or persistent COVID-19 were included. Descriptive analysis of primary scores was conducted. Given the non-normal distribution of data, the Mann-Whitney and Kruskal-Wallis tests were employed. Spearman and Kendall correlations were employed to assess the relationship between WAI and WAS, also used weighted Kappa to estimate the degree agreement between WAI and WAS. Logistic regression models were utilized to study determinants influencing WAI and WAS, categorized as poor or moderate. Results: WAI had an average score of 32.98 (SD = 10.28), whereas WAS had an average of 5.95 (SD = 2.77). Significant differences were observed in both WAI and WAS across the same variables. Strong and statistically significant correlations were evident between WAI and WAS (rs = 0.83, p < 0.001). All the variables used in the logistic regression model (gender, the sector employment, and previous chronic diseases) were statistically significant in both questionnaires. Conclusion: WAS questionnaire could be used as a tool for reliable assessment of work ability among Spanish workers with Post COVID-19 condition or Persistent CO-VID-19.

Body mass index is not associated with sperm-zona pellucida binding ability in subfertile males

Lifestyle factors, such as weight and nutritional status may affect male fertility, including sperm fertilization ability. The objective of this retrospective study was to evaluate the association between body mass index （BMI） and sperm-zona pellucida binding ability assessed according to the zona binding （ZB） test, which has been described to be a relevant diagnostic tool for the prediction of in vitro fertilization （IVF） ability. Three hundred and six male patients from couples diagnosed with primary idiopathic or mild male factor infertility were included. Correlations between BMI and semen parameters according to ZB test indices were assessed, together with frequencies of positive and negative tests across the BMI categories. In this selected population, BMI was not related to conventional semen parameters or sperm quality assessed according to the ability of spermatozoa to bind to the zona pellucida. The previously described poor outcomes of IVF procedures in cases of male obesity could be due to other sperm defects, such as alterations of sperm capacitation or acrosome reaction. The link between male BMI and biological outcomes during IVF procedures, such as fertilization rates, should be further evaluated.

Measuring Research on County Agricultural Technological Innovation Ability Index

Taking the mechanism of technological construction guidance theory and mode which consists of "objective-construction-evaluation-construction-objective" as a starting point, on the basis of county agricultural technological innovation ability and its index definition, this paper researches the constructing system of county agricultural technological innovation ability. Firstly, on the basis of defining county agricultural technological innovation ability and the definition of index, according to the principle of purposefulness, scientificity, systematicness, integration of dynamic state and static state, integration of quantitativeness and qualitativeness and so on, we construct the multi-level measuring system of county agricultural technological innovation ability, including 4 first-level indices, namely technological innovation environment, technological innovation basis, technological innovation ability, and technological innovation efficiency; 15 second-level indices, such as technological policy, technological system mechanism, technological institution construction, ability of innovation subject, ability of industrial expansion, scale merit, technological contribution rate. Moreover, this system has 45 third-level indices. Then, by using unascertained mathematics method and AHM method, we establish the multi-level unascertained composite measuring model of county agricultural technological innovation ability index. Finally, by using the survey data of one county in Hebei Province, and the established county agricultural technological innovation ability index model, we get the county agricultural technological innovation ability index of 0.711 by calculation, that is, the innovation ability is at the intermediate level, namely the modern agricultural sub-stage. The empirical research proves the correctness and applicability of this model.

Sprouting Value Index and Viability Percentage： An Integrated Measure of Vegetative Planting Material

Rooting ability of indole 3-butyric acid （IBA）-induced stem cuttings in vegetative regeneration experiments depends on various parameters, which can be entrenched using sprouting value index （SVI）, a mathematical approach. In this study, field studies were carried out in Tabebuia rosea to generate clonal planting stock regeneration using three rooting medium at a location in Central Kerala, Peninsular India, for three consecutive years from October 2014 till June 2016 at four months regular intervals. Three IBA concentrations, viz., 200, 500 and 1,000 ppm, have been used and the data obtained was evaluated using SVI method in order to establish the suitable medium, which gives the maximum rooting results. Control cuttings did not record rooting in any of the trials. The high SVI was obtained when stem root cuttings planted in root trainers with coir pith compost （RTCP） for all the three concentration of IBA applied. Sprouting percentage was marked up and the delay in completion of sprouting/rooting initiation decreased by the use of IBA treatment.

热水解对鸡粪和牛粪厌氧消化及重金属风险的影响

为探究热水解预处理对鸡粪和牛粪在厌氧消化过程中产气效率的提升作用以及对消化残渣中重金属形态变化及潜在生态风险的影响。该研究以鸡粪和牛粪为处理对象,采用热水解处理技术,开展了连续中温厌氧消化试验。考察了热水解对畜禽粪污可生化性和重金属迁移风险。该研究还评估了连续施用厌氧消化鸡粪和牛粪15 a后土壤中重金属的积累量和Hakanson潜在生态风险指数。试验发现,鸡粪中木质纤维素含量占干固体总量的25%,牛粪为57.7%。热水解处理能够增强牛粪中木质纤维素的水解,热水解后木质纤维素的降解率为19.2%;但热水解对鸡粪的木质纤维素水解影响不明显,降解率仅为5.3%。鸡粪挥发性固体(volatile solid,VS)产气率为482 L/kg,热水解后产气率提升了12.4%;牛粪产气率为321 L/kg,热水解后产气率提升了31.2%。仅通过热水解不能降低鸡粪中重金属的迁移风险;而经过厌氧消化后,除Hg和Ni外,其他重金属迁移风险均降低到了低风险水平。牛粪经过热水解和厌氧消化处理后重金属向残渣态转换,但迁移风险没有明显改善。连续施用鸡粪和牛粪15 a后,土壤未出现的重金属积累,且15 a内总潜在生态风险等级处于低风险。该研究结果可为鸡粪和牛粪的能源化、无害化处理以及土地利用应用提供了理论依据和数据指导。
