Testo completoAbstract (sommario):
The expansion of bio-based value chains is prioritized through various European Union (EU) policy initiatives. Due to the growing awareness of the importance of a sustainable bioeconomy in Europe, the need to increase the availability and quality of statistics is increasing. There are several essential aspects lacking, including (i) comprehensive databases and statistics for bio-based sectors; (ii) transparent methodology for bio-based data collection; and (iii) integrated value chain data and indicators that illustrate the flows of different bio-based commodities. The aim of this paper is to develop a bio-based material flow monitor to measure the physical contribution of industries to the bioeconomy. The material flow monitor describes physical material flows (including biomass) to, from, and within the economy. It is recorded in the form of supply and use tables. To measure the bioeconomy, the BioSAM database, along with disaggregated commodities and activities, are used. Data regarding waste generation/treatment and CO2 emissions/sequestrations are added to assess the impact on climate change. The results indicate that the bioeconomy in the EU is underreported due to a lack of data, leading to an insufficient understanding of its contribution to the economy. It can also be concluded that the data from the BioSAM tables are the most complete and have the highest disaggregation level for commodities and sectors, allowing one to measure the significance of the bioeconomy.

Testo completoAbstract (sommario):
The development of the bioeconomy—or the substitution of fossil-based materials and energy by bio-based solutions—is considered a strategic economic orientation by the European Commission and its Green Deal. This paper presents a methodology to monitor the contribution of the bioeconomy to jobs and growth within the European Union (EU) and its Member States. Classified as an ‘‘output-based’’ approach, the methodology relies on expert estimations of the biomass content of the bio-based materials produced in the EU and the subsequent calculation of ‘‘sectoral’’ bio-based shares by using Eurostat statistics on the production of manufactured goods (prom). Sectoral shares are applied to indicators of employment, and value added is reported in Eurostat–Structural business statistics. This paper updates the methodology and time series presented in 2018. The bioeconomy of the EU (post-Brexit composition) employed around 17.5 million people and generated €614 billion of value added in 2017. The study evidences structural differences between EU national bioeconomies, which become more pronounced over time, especially in terms of the level of apparent labour productivity of national bioeconomies. Finally, this paper describes cases of transition over the 2008–2017 period.

Testo completoAbstract (sommario):
The drying of bio-colloidal droplets can be used in many medical and forensic applications. The whole human blood is the most complex bio-colloid system, whereas bovine serum albumin (BSA) is the simplest. This paper focuses on the drying characteristics and the final morphology of these two bio-colloids. The experiments were conducted by varying their initial concentrations, and the solutions were dried under various controlled substrate temperatures using optical and scanning electron microscopy. The droplet parameters (the contact angle, the fluid front, and the first-order image statistics) reveal the drying process’s unique features. Interestingly, both BSA and blood drying droplets’ contact angle measurements show evidence of a concentration-driven transition as the behavior changes from non-monotonic to monotonic decrease. This result indicates that this transition behavior is not limited to multi-component bio-colloid (blood) only, but may be a phenomenon of a bio-colloidal solution containing a large number of interacting components. The high dilution of blood behaves like the BSA solution. The ring-like deposition, the crack morphology, and the microstructures suggest that the components have enough time to segregate and deposit onto the substrate under ambient conditions. However, there is insufficient time for evaporative-driven segregation to occur at elevated temperatures, as expected.

Testo completoAbstract (sommario):
An extensive survey was performed covering all the regions of the country to find out the overall impacts of bio-digester on the economy of livestock farmers. Five districts were selected; ten farmers with having bio-digester of 3.2 m3 on average and ten farmers who have no bio-digester were selected from each district. Through direct interviewing and farm monitoring, all farm characteristics, i.e., diurnal biogas production, power generation, cooking time, income and expenditures, farmer’s gross earnings, and manure management practices data were collected accordingly. Descriptive statistics and student t-test was made to express the comparison response of the farms by using XL and SPSS software. It was observed that the owners of anaerobic digesters earned significantly (p < 0.001) more than the traditional farmers by selling animals and biogas (1715 & 306; 1146 & 0.00 USD, respectively). Not only that, by selling milk and fresh manure, the owners of bio-digester harvested more (p < 0.05) annual income than non-bio-digester farmers (4162, 3408 & 60.91, 44.63 USD, respectively). Though the expenditure of farmers having digester was high, but in a single fiscal year, they earned more (p < 0.05) profit than the conventional farmers (USD 4329 & 2842, respectively). However, owners of bio-digester used 67.2 % of their produced manure for gas production. Regarding storing manure as biomass and using it for cooking purposes significant difference (p < 0.001) was observed that was also reflected in the total manure management system of a farm. The farmers having no bio-digester stored 71.95% of their total manure in solid form, whereas the farmers who had bio-digester only stored 20.4% of their manure, which made a significant (p < 0.001) difference. From the biogas chamber, in an average one farmer used a gas stove for 4-5 hours and a gas lamp for 6-8 hours, which saved at least the expenditure of 18 USD per month/household. The notable thing was that the bio-digester alone contributed 7% to those farmers’ gross economy by producing gas. It can be recommended that the rural householders could generate power by installing bio-digester and turn a small bio-digester as a beneficial avenue of their household economy.

The study analysed farmers’ preferences and perception influencing decision to grow biofortified provitamin A cassava. Specifically, the study described the socio-economic characteristics of cassava farmers in the study area; identified sources of information on biofortified provitamin A cassava; ascertained farmers’ perception of the key attributes of biofortified provitamin A cassava; ascertained farmers’ preference for biofortified provitamin A cassava; analysed sio-economic determinants of willingness to grow bio-fortified provitamin A cassava, and, constraints that hinder farmers’ decision to grow bio-fortified provitamin A cassava. It was hypothesized that the socio-economic characteristics of farmers significantly influence the decision to grow bio-fortified provitamin A cassava. Structured questionnaire and interview schedule were used to elicit data from 90 cassava farmers in the study area. Data collected were analysed using descriptive and inferential statistics. The result revealed that farmers in the study area were mostly female, married, with a mean age of 50 years, mean years of formal education of 12 years, farming experience of 6 years and a mean household size of 6 persons. The sources of information on bio-fortified provitamin A cassava include agricultural extension agents, farmer groups and radio. The result also showed that farmers perceived bio-fortified provitamin A cassava to be able to make yellow Garri (Cassava granules); have low sugar content. The farmers preferred bio-fortified provitamin A cassava because of its low sugar content, ability to make yellow cassava granules (Garri) which makes it attractive for selling, and contain vitamin A which is necessary to reduce blindness. Poor access to information, poor access to bio-fortified provitamin A cassava stem, and high moisture content were some of the major constraints that affect the decision to grow bio-fortified provitamin A cassava by farmers’ in the study area. The study recommends that farmers should be given easy access to bio-fortified provitamin A cassava stems and extension agents should make more visits to cassava farmers to enlighten them on the benefits of growing biofortified provitamin A cassava.

Maximum likelihood estimation is a method of estimating the parameters of a statistical model in statistics. It has been widely used in a good many multi-disciplines such as econometrics, data modelling in nuclear and particle physics, and geographical satellite image classification, and so forth. Over the past decade, although many conventional numerical approximation approaches have been most successfully developed to solve the problems of maximum likelihood parameter estimation, bio-inspired optimization techniques have shown promising performance and gained an incredible recognition as an attractive solution to such problems. This review paper attempts to offer a comprehensive perspective of conventional and bio-inspired optimization techniques in maximum likelihood parameter estimation so as to highlight the challenges and key issues and encourage the researches for further progress.

Testo completoAbstract (sommario):
The relatively young science, ecotoxicology, has changed substantially during the last decade from a more practically oriented science to a basic one with more focus on problem solving and the search for causalities in the study of effects. In this article the origin and position of the discipline is analysed, as well as the influence of new developments in the fields of bio-informatics and genetics. The merit of this is discussed and the conclusion made that ecotoxicology can be seen as a separate science, notwithstanding its multidisciplinarity. A review is given of the historic development of the subject and its connection with broad ecology as an example of stress ecology. The importance of incorporating the most recent research developments in biology into ecotoxicology, such as bio-informatics, multivariate statistics and genomics, is discussed. The view is expressed that ecotoxicology will be changing in the near future to include ecotoxicogenomics. This will be a result of the interaction between ecotoxicology and ecology on the cross roads with genomics and bio- informatics.

Bio-based economy as a part of circular economy covers all sectors and systems that use biological resources. It is one of the largest and most important sectors of the EU and includes agriculture and forestry, fisheries, agro-food, biomass and bio-based products. Its annual turnover is about 2 trillion euros, and it employs about 18 million people. Bio-economy is also a key area for stimulating growth in rural and coastal areas. In Bulgaria there is still a limited understanding of the added value of eco-innovation, the effects of defragmentation of the value chain, the consequences of the limited application of environmental investments, as well as the lack of appropriate financial instruments stimulating technological progress. The focus of the research was to measure the innovation-supportive culture exhibited through innovativeness, creativity, business alertness and risk taking and how and how they influence the effectiveness of bio-enterprises. The research focused on a population of 285 enterprises for the production of organic food from all Bulgarian regions. Collected data were analyzed using descriptive and inferential statistics with the aid of Statistical Package for Social Sciences (SPSS). Correlation and multiple regression were employed to analyse the data and test the hypotheses. The study revealed that innovativeness, creativity, business alertness and risk taking were significant for the formation of an innovations-supportive culture and affecting performance of Bulgarian bio-economy. The study concluded that innovation-supportive culture or lack of it has a major effect on business performance and if any organization is bended towards development and growth, it would have to embrace this concept.

Testo completoAbstract (sommario):
This study investigates stakeholder knowledge, attitudes, and public perception concerning biofuels as an enabler towards a bio-based economy. In innovation and adoption studies, perceptions play a critical role in the acceptance of a technology. Biofuels have been touted as a clean fuel with an ability to reduce greenhouse gas emissions while simultaneously creating employment and growing economies. South Africa is in the process of transitioning towards a bio-based economy. Accordingly, policies and institutions have been developed to promote biofuels production and distribution. Knowledge, attitude and perception (KAP) surveys were carried out to deepen knowledge and understanding of the stakeholder’s KAP. Emails as well as telephonic and group interviews based on open questions and social media were used to gather data. The study employed cluster, purposive random and snowball sampling to select the participants with descriptive statistics, thematic analysis and discourse analysis used to analyse the data. The study found that the introduction of biofuels presents many opportunities and benefits for the economy and unlocking the potentials for the rural entrepreneurs. Stakeholders have concerns and issues regarding the use of biofuels on their internal combustion engines. The study recommends proper communication and education should be done on the benefits of biofuels in a bio-based economy.

The present study was conducted to evaluate the quality and bio-functional properties of Portuguese honeys of different botanical and geographical origins. Quality parameter analyses included the determination of palynological (predominant, secondary, minor and isolated pollen percentage), physicochemical (°Brix, moisture content, pH, electrical conductivity, free acidity, total dissolved solids, salinity, vitamin C content and specific weight) including colour-metrics (CIELAB, Pfund and colour intensity determinations), along with volatile compounds identification using solid phase micro-extraction coupled to gas chromatography mass spectrometry. Bio-activity parameter analysis included the determination of in vitro antioxidant activity and total phenolic content using the 2,2-diphenyl-1-picryl-hydrazyl and Folin-Ciocalteu assays, respectively. Melissopalynological analysis showed that Portuguese honeys were classified as eucalyptus, chestnut and heather, recording significant variations (p < 0.05) among physicochemical, volatile and bio-activity parameter analyses according to both: botanical and geographical origin. Based on the multi-parameter analysis data Portuguese honeys could be characterized by a distinctive colour, a characteristic aroma, whereas conform to the European legislation relating to honey identity and quality. Specific attention should be given in the case of heather honey which showed the highest in vitro antioxidant activity and total phenolic content. Parameters that were also highly correlated using bivariate statistics.

The present work represents potential bio-sorbents: Tilia cordata (little leaf linden) and Foeniculum vulgare (fennel). The copper removal was operated in batch procedure. Adsorbent mass, copper ion concentration, pH, time, and temperature considerations were inspected. The highly beneficial provisions for copper adsorption are 10 mg /L as preliminary concentration, 0.2 g as Tilia cordata and Foeniculum vulgare mass and pH 5.5 and 5.23 for Tilia cordata and Foeniculum vulgare. Adsorption statistics follow the Langmuir isotherm with qmax of 29.35 mg/g for Tilia cordata and 32.98 mg/g for Foeniculum vulgare. The removal procedure kinetics was provided perfectly via second-order equations. It was revealed that the copper ion adsorption procedure on mutual bio-sorbents is a spontaneous procedure, and is endothermal for Tilia cordata and Foeniculum vulgare. Characterization of Tilia cordata (little leaf linden) and Foeniculum (vulgare fennel) were inspected with a scanning electron microscope (SEM), Vis-IR Spectroscopy, GC-mass and milling cutter. A distinctive development in the adsorbent surface was exhibited through scanning electron microscope. The removal efficiency reached to 93.34 & 95.4 for Tilia (Tilia cordata) and Fennel (Foeniculum vulgare) respectively at 0.5 M bio-sorbent which indicated that Tilia (Tilia cordata) and Fennel (Foeniculum vulgare) has good renderability and stability.

The bio-indicator potentials of two invertebrate species, Eudrilus eugeniae (earthworm) and Pachybolus ligulatus (millipede) in toxic metals impacted soils in Akwa Ibom State, in the Niger Delta region of Nigeria were assessed. The study involved collection of Eudrilus eugeniae and Pachybolus ligulatus, and their site soil samples from different impacted and non-impacted soils in ten locations spread over four Local Government Areas. Toxic metals (Pb, Fe, Zn, Ni and Cd) in soils and in the bio-indicator organisms were analysed using Atomic Absorption Spectrometry, after acid digestion. Geo-accumulation Index (Igeo) was used to measure the extent of soil pollution; Bio-Accumulation Factor (BAF) to compute the metal uptake from soil by bio-indicators; and multivariate statistics to identify interrelationships among metals and the pollution sources. Metals in all soils were higher than the background levels, and were classified as unpolluted to very strongly polluted. Pb, Fe, Zn and Cd were higher in Eudrilus eugeniae, and Ni in Pachybolus ligulatus at 0.05 level. The organisms absorbed all metals (BAF<1), but Eudrilus eugeniae accumulated Cd and Fe and Pachybolus ligulatus, Ni and Fe (BAF>1). Metals were clustered into three (Eudrilus eugeniae) and two (Pachybolus ligulatus) dissimilar groups. Two principal components extracted, each for Eudrilus eugeniae and Pachybolus ligulatus accounted for 64% and 72% of total variations, respectively. The invertebrates exhibited varying levels of affinity in metals uptake. Eudrilus eugeniae appeared to accumulate Pb, Fe and Cd more, and could serve as a better bio-indicator for monitoring these metals. Pachybolus ligulatus accumulated 3-folds more Ni, and could provide a monitoring tool especially in agriculture, in the Niger Delta Region of Nigeria, plagued by crude oil pollution of its land and water bodies.

Testo completoAbstract (sommario):
The literature on reliable indices, suitable bio-indicators, taxonomic level, frequency of measurements, and replications on benthic macroinvertebrates remains scarce in Malaysia. In addition, no review study was conducted using bibliometric analysis related to this discipline. Thus, this review aimed at gap and bibliometric analysis of publications on benthic macroinvertebrates as potential biological indicators. Sixty-six relevant scientific research papers from 2011 to 2022 were selected from the different databases. Then, descriptive and inferential statistical analyses were performed to assess the most reliable potential bio-indicators for river assessment and monitoring. Visualized statistics regarding bibliographic coupling analysis of authors, journal proceedings, and organizations were analyzed. The findings revealed that publications on invertebrates had no significant relationship in the last ten years (r = 0.241; p > 0.05). Most publications on macroinvertebrates in Malaysian rivers were found in the Scopus database (53.57%). Therefore, research articles must be published in journals included in the Journal Citation Report (JCR) to improve their quality further. Besides, benthic macroinvertebrates are commonly identified only up to the family level (47%) due to incomplete tropical benthic macroinvertebrates identification keys. As such, using environmental DNA methods with the power of next-generation sequencing has come in handy in bio-indicator species identification. Among the potential bio-indicators found in Malaysian rivers are Chironomidae (9.11%), Baetidae (8.87%), and Hydropsychidae (8.62%). Based on the approaches utilized in analyzing benthic macroinvertebrates as bio-indicators, in-depth research such as bioassay and toxicology tests is necessary to realize the potential bio-indicators fully. Many studies focused on recreational rivers in Peninsular Malaysia. Therefore, research studies would be expanded to urban rivers and rivers in Sabah and Sarawak. Also, to overcome the limitation of the single biotic index, developing a multimetric index to evaluate the water quality by selecting many river basins is essential. Bibliographic analysis showed that the Institute for Tropical Biology and Conservation, Universiti Malaysia Sabah, made the greatest total link strength. The Serangga Journal published the highest number of research articles. Finally, utilizing advanced technologies is recommended to address Malaysia's lack of potential bio-indicator studies.

Abstract Background Risankizumab (RZB), a selective interleukin-23 inhibitor, demonstrated superior efficacy over placebo (PBO) as induction and maintenance therapy in patients with moderate to severe Crohn’s disease (CD). Here we compared the efficacy and safety of RZB in inducing and maintaining clinical remission and clinical response in patients with CD who demonstrated intolerance and/or inadequate response (IR) to biologic therapies (with prior bio-failure) versus those who demonstrated IR to conventional therapies only (without prior bio-failure). Methods This subgroup analysis included pooled induction data from patients randomized to receive intravenous (IV) RZB 600mg (N=527) or placebo (PBO) IV (N=362) every 4 weeks (wks) for 12wks in the ADVANCE+MOTIVATE studies, and maintenance data from IV RZB responders who were randomized to subcutaneous (SC) RZB 360mg (N=141) or withdrawn from RZB to receive PBO SC (withdrawal [PBO SC], N=164) every 8wks for 52wks in FORTIFY. Clinical remission (per CDAI and per stool frequency [SF]/abdominal pain score [APS]), CDAI clinical response, enhanced SF/APS clinical response, and maintenance of clinical remission were evaluated in the overall population, and in subgroups with and without prior bio-failure, using non-responder imputation. Only descriptive statistics were used for the subpopulations (Endpoints are defined in Table footnotes). Safety was assessed throughout the studies. Results Approximately three-quarters of randomized patients included in the subgroup analyses had prior bio-failure (ADVANCE+MOTIVATE: 75.4%; FORTIFY: 73.8%). Among the subpopulations, numerically higher rates of clinical remission (CDAI and SF/APS), CDAI clinical response, and enhanced SF/APS clinical response were observed at the end of induction (wk12) among patients receiving RZB 600mg IV versus PBO IV (Figure); rates were numerically higher in the subpopulation without prior bio-failure than with prior bio-failure. FORTIFY Wk52 response rates for these endpoints, along with maintenance of clinical remission, were higher in the RZB 360mg SC arm compared to the withdrawal (PBO SC) arm in both subpopulations, with numerically higher rates observed for the subgroup without prior bio-failure (Figure). RZB maintenance treatment was well-tolerated and no new safety signals were observed. The safety profile of RZB has been reported previously.1,2 Conclusion Across the induction and maintenance studies, compared to PBO, RZB treatment led to greater clinical remission and clinical response in patients with CD independent of prior biologic experience. The subpopulation without prior bio-failure achieved higher rates of symptomatic remission.

This paper describes a research project focused on identifying student-teachers’ critical thinking performance levels in scientific reasoning and, secondly, on analyzing the reliability level of the Critical Thinking Tasks test (CTT). As part of the methodology, a non-probabilistic sample of 129 teacher education students from different majors at Bio-Bio University was considered, and the Critical Thinking Task test was applied to collect data. The data analysis was conducted using descriptive statistics, reliability measures and mean score differences. The data showed that the instrument is reliable (α=0,79); there is also a relatively low performance in the global test and its dimensions; and there are differences between the different teacher education programs. It is concluded that the instrument is reliable, and findings support the idea that knowledge-based areas influence critical thinking. Finally, it is necessary to strengthen specific sub-skills to enhance critical thinking as a contribution for scientific reasoning.

Testo completoAbstract (sommario):
Monitoring bioeconomy transitions and their effects can be considered a Herculean task, as they cannot be easily captured using current economic statistics. Distinctions are rarely made between bio-based and non-bio-based products when official data is collected. However, production along bioeconomy supply chains and its implications for sustainability require measurement and assessment to enable considered policymaking. We propose a starting point for monitoring bioeconomy transitions by suggesting an adapted framework, relevant sectors, and indicators that can be observed with existing information and data from many alternative sources, assuming that official data collection methods will not be modified soon. Economic–environmental indicators and innovation indicators are derived for the German surfactant industry based on the premise that combined economic–environmental indicators can show actual developments and trade-offs, while innovation indicators can reveal whether a bioeconomy transition is likely in a sector. Methodological challenges are discussed and low-cost; high-benefit options for further data collection are recommended.

AbstractEvaluations of the factors influencing the adoption of agricultural and natural resource management technologies among small farmers in developing countries have been mostly limited to qualitative discussions or simple descriptive statistics resulting in superficial and inconclusive findings. This study introduces the use of Poisson Count Regressions as a statistically appropriate procedure to analyze certain common types of adoption data. It uses them to assess the impact of key socio-economic, bio-physical, and institutional factors on the adoption of integrated pest management, agroforestry, and soil conservation technologies among small farmers in three Central American countries: Costa Rica, Panama, and El Salvador.

ABSTRACT Profitable farming is a prime target of all farmers regardless of the scale of production adopted and the veritable opportunity to attain the threshold of bumper harvest is not unconnected with the adoption of new technology. Bio-fortified vitamin A cassava remains the best option for farmers to experience improvement in cassava performance in both the quality and quantity terms and they are encouraged to adopt it in order to improve their households’ welfare. The survey was launched to investigate the effect of bio-fortified vitamin A cassava on the poverty status of the farming households in Nigeria using Oyo State as a case study. A Multistage sampling technique was used to sample a total of 186 cassava farmers comprising 92 adopters and 94 non-adopters of bio-fortified vitamin A cassava variety using copies of well-structured questionnaires. Parametric tools used were descriptive statistics and probit regression for socioeconomic characteristics and adoption status analysis. The socioeconomic results showed that both the adopters and non-adopters were in the productive ages of 42 years and 59 years respectively. The majorities of farmers in the two categories were married and had formal education. Years of experience possessed by them were 11 years and 18 years while both groups were members of associations. Poverty classification result showed 41.3% of adopters being poor while 83.0% of non-adopters were poor. Marital status (2.1271<p=0.05), education (1.1510; p<0.1), seasonal income (0.0757; p=0.05) and poverty status (I.6019; p<0.1) had influence on the farmers’ adoption status while lack of credit was voted highest among the factors militating against adoption of bio-fortified vitamin A cassava. It is therefore recommended that stakeholders in the crop enterprise should make frantic efforts in providing credit and other basic inputs that will enhance improved vitamin A adoption.

Objectives The purpose of this study was to understand the importance of the Bio-healthcare Digital Living Lab for solving community problems and to suggest policy improvement so that it can be utilized based on the speci-alized fields of university. Methods From September 1 to October 10, 2022, the survey was conducted on 150 students enrolled in bio-healthcare courses at universities in the Jeonbuk region, as well as faculty and community industrial company related Bio-healthcare department. The collected data were analyzed using the IBM SPSS Statistic ver. 22.0 stat-istical program. Frequency analysis, descriptive statistics, χ-square, independent t-test, and 1-way ANOVA were performed to analyze the data. Results The study showed satisfaction with the community living environment at 3.68 out of 5. By gender, it was higher in men(3.77±0.90) than in women(3.62±0.85), and by age, it was highest in people in their 20s(3.86±0.80), and satisfaction tended to decrease as age increased. Among local issues, ‘culture/leisure’ was recognized as the most important in terms of quality of life(28.2%) and an area in urgent need of improvement(27.6%), and the area expected to have the greatest ripple effect if improved was ‘jobs/start-up’(33.9%). In addition, there was a stat-istical difference in areas requiring urgent improvement and areas with large ripple effects depending on age and status(p<.05). They recognized that the bio-healthcare field would play an important role in resolving local is-sues(52.7%), and that local residents‘ participation was necessary in promoting it(70.4%), but the highest re-sponse was that they would consider their participation depending on the nature and direction of the project (48.8%). And, teenagers showed statistically significantly lowest scores in terms of possibility of solving local is-sues, possibility of improving quality of life, need for resident participation, and willingness to participate (p<.05). Conclusions In process of promoting a digital living lab in the bio-healthcare, an accurate preliminary analysis of the needs of local community residents regarding its nature and direction is necessary. And, in promoting a digital living lab that solves community problems, universities must play a role in building a digital living lab infrastructure specialized in the bio-healthcare field while experimenting with technology, products, and services through com-munity linkage. Lastly, for the expansion and sustainability of community bio-healthcare living labs, it is necessary to plan a living lab platform that considers both the community's needs and the university's specialized fields, and it is need to develop into an infrastructure rather than a project type.

This article is a direct consequence of the authors' desire to discuss the role of statistics in data analysis. The analysis of coronavirus (COVID-19) databases are used as to show simple, but powerful statistical frameworks. We do believe that models for assessing future trends in temporal data in general, and in cases and/or deaths of COVID-19, belongs to the area of (Bio)Statistics. Just as engineers use knowledge of physics, chemistry and often architecture, when constructing bridges, buildings and roads, statisticians use knowledge of mathematics, computer science and even physics for modelling, analysing, and forecasting in order to transform data into information. While the statistician's contribution is rarely acknowledged, everyone knows that a building is a work of an engineer. Nonetheless, nowadays statistics has been gaining the attention that it deserves due to the rise of big data and data science that was built on the foundationsof statistics. This article shows that, even with only basic knowledge of statistics, one can adequately collaborate with the community in dealing with very important issues such as the COVID-19 numbers. In order to model and to obtain predictions we use well-known distributions to statisticians working on survival analysis: gamma, Weibull and log-normal distributions. We also make use of singular spectrum analysis, a simple non-parametric time series methodology, for an analogous purpose. Survival analysis is a research area widely used in Biostatistics and even in Reliability, while time series analysis is widely used across areas where the data is measured along the time.

The study attempts to determine the training needs of the farmers emphasizing nine selected major thematic areas. Under each major component, specific and relevant training needs item were collected and systematically incorporated into an interview schedule and administered in terms of frequency of training imparted. Four districts were purposively selected for the study and a total of eighty farmers were randomly selected from four districts. Primary data were analyzed using descriptive statistics. The study revealed that more male was involved in farming and 45% farmers were middle age category (30-39 years). Majority of the farmers completed primary level of education compared to other categories and family size of more than half (60 %) of the respondents was three. Majority number of respondents (57%) had more than 10 years farming experience. A small number of farmers (8.75%) had owned agricultural land and 45% had land between 0.50- 1 hectare. More than 75% of annual gross income of 57.50% farmers came from agricultural activities. More than half (55%) of the respondents collected information on crop and its varieties by own attempt while about 34% was informed from seed seller or dealer. Farmers in Chattogram district had first priority to get training on integrated pest and diseases management, production of bio control agents and bio pesticides, marketing and transportation. Water management, integrated pest and disease management, vermi-compost production, marketing and transportation ranked first in Khagrachori district. The areas of priority for training in Rajshahi district were production and management technology, processing and value addition, marketing and transportation, integrated pest and disease management, water management and vermi-compost production. Training on integrated pest and disease management, bio-control of pests and diseases, production of bio control agents and bio pesticides, production of off-season vegetables, vermi-compost production, marketing and transportation were most emphasized by the respondents in Rangpur district. Respondents defined identification of adulterated fertilizer, insecticide and pesticide application, disease and insects of mango varieties and fruit bagging system of mango as very good type of training. The study concluded that there is an urgent need to design regular training programs in identified thematic areas to fulfill the knowledge gap among the farmers of Bangladesh.Bangladesh J. Agril.

Abstract Introduction: In the context in which physical activity is considered today to be a profession, the profile faculties must seek both, the readaptation of study programs to the requirements of the labor market and the updating of student recruitment policies. This study‘s aim is to analyse AVU‘s PESF admission trials from a bio-motric perspective, in order to improve the admission methodology. Methods: The study is a longitudinal one, and subjects are applicants from the 2017 and 2018 academic year (N=117, M=25±9.20 years, out of which B=88, F=29). Methodological approach: a statistical analysis of applicants‘ admission trials using the IBM SPSS Statistics 19 (C.I. =95%) programme. Trial results have been equated to grades. Correspondingly, the gathered data has been compared to: 11th and 12th grade curricular areas, with data included in Faculty of Physical Education and Sport‘s Report (University of Bucharest) regarding the bio-motric potential of Romanian students (2015) as well as with admission methodology related data from other faculties. Results: The gathered results – grouped per trial type- are: speed Ms= 7.3±2.47, standing jump Msj=6.6±2.46, push up Mpu= 9.86±0.73, football Mf=8.18±1.71, handball Mh= 6.83±2.82, basketball Mb=6.56±4.24, volleyball Mv=8.87±0.97, gymnastics Mg=7.83±1.94. Conclusions: AVU‘s FEFS admission policy requires better suited trials in relation to the bio-motric potential (qualities and motor skills) of today‘s graduates. Also, FEFS‘ educational offer (meaning study programmes, study subjects, curricular content) must be able to better cover work force dynamics and labour market requirements.

The uncontrolled waste generation is a prevailing environmental concern where waste management is a critical issue in Sri Lanka. Even though different methods are practicing, insect-basedbio-degradation is forthcoming. Black soldier fly larvae (BSFL,Hermetia illucens) based emerging technology has recognized for the conversion of biodegradable waste into potentially more sustainable and marketable nutrient rich compost and animal feed rich with crude proteins. The study aims evaluate the potentials to introduce BSFL based biodegradation and to upgrade protein livestock feed sources by overwhelming urban catering bio-degradable waste in Ratnapura, Balangoda and Embilipitiyaurban council areas. Eighty-eight questionnaires were administrated through random sampling and the results were interpreted by descriptive statistics and bivariate correlation. More positively 97.7% were having the waste collection service supplied by local authorities (LA) with 93.2% daily collection. Importantly LA had a policy to collect the separated waste only. Even though 98.8%, 56.8% and 92.0% of the respondents were not known regarding BSFL protein production, live feeding and composting, 55.7% were willing to produce BSFL by their own bio-degradable waste. 46.6% and 71.6% were willing to sell 1kg of compost and BSFL larvae by Rs. 100-Rs.200 price for expected protein upgrade program in future. Further 60.2% were willing to use a BSFL based compost bin where it was requested to be compatible with the limited space. Since locally it is hardly evidenced regarding this insect-based technology, correlation results indicated the need of more awareness mainly BSFL bio-conversion and relevant technical knowhow procedures along with popularize BSFL based protein production.

Particulate organic carbon (POC) is a key biogeochemical parameter that helps us characterize export processes of the ocean. Ocean color observations enable the estimation of bio-optical proxies of POC (i.e. particulate backscattering coefficient, bbp) in the surface layer of the ocean quasi-synoptically. In parallel, the Argo program distributes vertical profiles of the physical properties with a global coverage and a high spatio-temporal resolution. Merging satellite ocean color and Argo data using a neural networkbased method has already shown strong potential to infer the vertical distribution of bio-optical properties at global scale with high space-time resolution. This method is trained and validated using a database of concurrent vertical profiles of temperature, salinity, and bio-optical properties, i.e. bbp, collected by Biogeochemical-Argo (BGC-Argo) floats, matched up with satellite ocean color products. The present study aims at improving this method by 1) using a larger dataset from BGC-Argo network since 2016 for training, 2) using additional inputs such as altimetry data, which provide significant information on mesoscale processes impacting the vertical distribution of bbp, 3) improving the vertical resolution of estimation, and 4) examining the potential of alternative machine learning-based techniques. As a first attempt with the new data, we used some feature-specific preprocessing routines followed by a Multi-Output Random Forest algorithm on two regions with different ocean dynamics: North Atlantic and Subtropical Gyres. The statistics and the bbp profiles obtained from the validation floats show promising results and suggest this direction is worth investigating even further at global scale.

Asian Journal of Advances in Agricultural Research 23, n. 2 (8 settembre 2023): 11–19. http://dx.doi.org/10.9734/ajaar/2023/v23i2457.

Bio-fortification of cassava increased its total carotenoid content (TCC) but may have boomerang effect on key quality traits of cassava like dry matter content (DMC). Meanwhile, DMC of cassava reflects its true biological and product yield. Therefore, this study was conducted to determine the relationship between TCC of some novel yellow root cassava varieties (YRCVs) and each of DMC and gari yield. Three bio-fortified YRCVs (TMSI010593, TMSI011368 and TMSI010539) and a white root variety (TMSI30572) as check were harvested 12 months after planting. The TCC (µg/g) and DMC (%) of the fresh storage roots were determined following standard procedures. Subsequently, the fresh storage roots were processed into gari and gari yield (t/ha) was estimated. Data collected were subjected to descriptive statistics, analysis of variance at 5% level of probability and correlation analysis. The check variety lacked TCC but had significantly higher DMC (34.34%) and gari yield (3.40 t/ha) than other varieties except variety TMSI010593 for DMC (33.95%). Total carotenoid content of the bio-fortified cassava varieties ranged between 7.81 µg/g (TMSI011368) and 10.23 µg/g (TMSI010593). Among the YRCVs, TMSI010593 consistently had the highest DMC (33.95%) and gari yield (3.2 t/ha) whileTMSI010539 had least values of 24.63% and 2.2 t/ha, respectively. The TCC of the fresh storage roots correlated negatively with DMC (-0.22) and gari yield (-0.22). Notably, TMSI010593 had a good combination of high TCC, DMC and gari yield, hence, it can deliver high gari yield and TCC to processors and consumers, respectively. Propagation of variety TMSI010593 is therefore encouraged because it can offer the triple benefits of food, nutritional and financial security.

"Aging and Allostasis: Using Bayesian Network Analytics to Explore and Evaluate Allostatic Markers in the Context of Aging".

Testo completoAbstract (sommario):
Allostatic load reflects the cumulative strain on organic functions that may gradually evolve into overt disease. Our aim was to evaluate the allostatic parameters in the context of aging, and identify the parameters that may be suitable for an allostatic load index for elderly people (>60 years). From previously published studies, 11 allostatic (bio)markers could be identified that sustain sufficient variability with aging to capture meaningful changes in health status. Based on reported statistics (prevalence of a biomarker and its associated outcome, and/or an odds/risk ratio relating these two), seven of these could be adopted in a Bayesian Belief Network (BBN), providing the probability of “disturbed” allostasis in any given elder. Additional statistical analyses showed that changes in IL-6 and BMI contributed the most to a “disturbed” allostasis, indicating their prognostic potential in relation to deteriorating health in otherwise generally healthy elderly. In this way, and despite the natural decline in variance that irrevocably alters the prognostic relevance of most allostatic (bio)markers with aging, it appeared possible to outline an allostatic load index specifically for the elderly. The allostatic parameters here identified might consequently be considered a useful basis for future quantitative modelling in the context of (healthy) aging.

This study aims to observe the possible negative effects that might occur on bio-chemistry and hemogram values of tennis players during the intense competition period by comparing the blood values of pre-competition period with 10 days of intense exercise. Blood samples were obtained from tennis team players who do not have any specific health problems and who study in university and regularly exercise. Mean age of the athletes are 22,40 ± 3,20 years and mean height is 179,83 ± 7,57 cm. This study is performed with 14 volunteer tennis players. Blood samples are obtained during the first day of the intense exercise program after the exercise, last day of the exercises and also right after the exercises. As per the obtained data, descriptive statistics are run (mean and standard deviation) and in order to compare the values of before and after the 10 days of intense exercise, Wilcoxon two related sample test was used. As per the results of the blood tests from before and after the exercise period, it is seen that values such as AST, ALT, MCH, MCHC and CK showed statistical significance (P<0.05). The athletes who prepared for the competitions with these values showed positive increases in bio-chemistry and hemogram values.

Testo completoAbstract (sommario):
Alzheimer’s disease (AD) is now classified as a silent pandemic due to concerning current statistics and future predictions. Despite this, no effective treatment or accurate diagnosis currently exists. The negative impacts of invasive techniques and the failure of clinical trials have prompted a shift in research towards non-invasive treatments. In light of this, there is a growing need for early detection of AD through non-invasive approaches. The abundance of data generated by non-invasive techniques such as blood component monitoring, imaging, wearable sensors, and bio-sensors not only offers a platform for more accurate and reliable bio-marker developments but also significantly reduces patient pain, psychological impact, risk of complications, and cost. Nevertheless, there are challenges concerning the computational analysis of the large quantities of data generated, which can provide crucial information for the early diagnosis of AD. Hence, the integration of artificial intelligence and deep learning is critical to addressing these challenges. This work attempts to examine some of the facts and the current situation of these approaches to AD diagnosis by leveraging the potential of these tools and utilizing the vast amount of non-invasive data in order to revolutionize the early detection of AD according to the principles of a new non-invasive medicine era.

Aim. Investigate the influence of treatment of maize plants with restrictive biological products on the formation of productivity of lines - parent components to optimize the elements of cultivation technology. Methods. 3-factor field experiment; measuring and weighing - to determine the structure of the crop; methods of mathematical statistics (analysis of variance, rectilinear and curvilinear correlation and regression). Results. Studies have shown that for the maximum manifestation of the sign "mass of 1000 grains" the optimal density is 70,000 plants ha-1. The increase in yield is positively influenced by the increase in the weight of 1000 seeds, which is due to both the genotype of the lines and the use of biologically active drugs Bio-gel, Helafit-combi. With the use of the drug Bio-gel laboratory germination increased by an average of 1.5 %, with the use of the drug Helafit-combi seed germination increased by 2.4 %. Conclusions. The maximum yield of the parent component DK 247 was observed at a density of 80 thousand plants/ha and treatment with the drug Helafit-combi - 4.89 t/ha. Mid-late lines - parent components DK 411 and DK 445 showed the highest yields at densities of 70,000 plants ha-1 and treatment with Helafit®-combi - 4.65 and 6.30 t/ha, respectively.
