Characterization of Japanese Apricot (Prunus mume) Floral Bud Development Using a Modified BBCH Scale and Analysis of the Relationship between BBCH Stages and Floral Primordium Development and the Dormancy Phase Transition

Bud dormancy is an important developmental stage that ensures that trees can tolerate environmental stresses in winter and bloom uniformly in the following spring. Regarding Rosaceae floral buds, exposure to chilling conditions promotes floral primordium development and the transition from endodormancy to ecodormancy. A subsequent period of warm conditions induces blooming. In Japanese apricot (Prunus mume), dormancy progression is accompanied by morphological changes that alter the bud appearance and internal structures. We used a modified BBCH scale and conducted microscopy analyses to elucidate the bud developmental stage of three cultivars with contrasting chilling requirements. The floral bud developmental period corresponding to BBCH stages 51–53 includes the transition from endodormancy to ecodormancy in all three cultivars. Male meiosis and microspore development occurred during this transition in high-chill cultivars, but were detected considerably later than the transition in the low-chill cultivar. A slow or suspended developmental phase was observed only for the high-chill cultivars upon completion of floral primordium organ differentiation, suggesting that chilling may be required to induce floral bud maturation and dormancy release only in high-chill cultivars. Possible relationships among BBCH stages, flowering-related morphological characteristics, and the dormancy phase transition in Japanese apricot are discussed.
Comparison of the accuracy of a free 3D camera system with the Ariel performance system

ABSTRACT The aims were: (1) to determine the accuracy and time-consuming of the automatic digitalization feature of 3D motion analysis systems; and (2) to determine the reliability of the 3D position when a football player performed a hard kick with spin. Four high-speed cameras (Casio ZR200 (512x384)) with a 240 Hz field rate were used. Automatic scanning of the Kinovea® and APAS® software was used. The accuracy was determined through mean absolute error, maximum absolute error, mean standard deviation of absolute error, and the variability values. The reliability was calculated with the Intra-Class Correlation. The mean absolute error (3.62 to 3.78 mm), maximum absolute error (9.09 to 11.61 mm), mean standard deviation of absolute error (0.01 to 0.59 mm), variability values (<1 mm), and the auto-digitalization time (16 to 31 minutes) were calculated and were within the values obtained in the literature. The reliability was determined with the Intra-Class Correlation, and the results were higher than 0.90, warrantied a high consistency for chosen software. The accuracy and the reliability intra-operator were determined, and the results indicated that it is possible to apply the free 3D camera system, with consistency in free-kick analysis.
Contour Ridge Tillage for Improved Crops and Fodder Trees Production in the Villages of Kani and Noumpinesso, Southern- Mali

In rural Mali shortage of livestock feed is a challenging phenomenon worsening day by day, particularly in the villages of Kani and Noumpinesso. The significant decrease in crops yield and Journal of Agricultural Studies ISSN 2166-0379 2021, Vol. 9, No. 2 http://jas.macrothink. org 551 livestock are due to persistent and continuous land degradation and over grazing. Soil water erosion and inappropriate or ineffective farming systems led to land degradation over the many years. A purposeful growing of fodder plant (fast growing trees species) and crops in interacting combinations for a range of benefits would be required using a technology that is easily adaptable by the rural farming communities. Contour ridge (CR) technology is a holistic approach that protects farmlands from erosion; increases soil moisture, nutrient availability for crops and associated fast growing trees. The CR technology in combination with forage and improved crop production systems were applied in Kani and Noumpinesso villages of southern Mali and resulted indicated that at the end of rainy season of 2017 and 2018 the application of CR technology significantly increased (p < 0.05) Gliricidia sepium and Leucaena leucocephala growth and development. Similar to 2017, in 2018 CR technology significantly increased (p < 0.05) sorghum, millet, maize, and cotton growth, yield, and economic benefit. At Kani during 2017 and 2018 season soil moisture was always significantly higher (p < 0.05) under fodder planted area than non-fodder planted area, and the difference was high with respect to farmlands without CR.
Occurrence and distribution of ochratoxin A-producing fungi during post-harvest process of cocoa (Theobroma cacao L.)

The occurrence of ochratoxin A (OTA) and OTA-producing fungi in cocoa beans has been previously reported to be linked to harvest and post-harvest treatment conditions. The aim of this study was to identify OTA-producing fungi during harvest, fermentation, drying and storage of cocoa beans from two farms located in the most important cocoa-producing region in Mexico, and their relationship with OTA levels of contamination. A high contamination of ochratoxigenic fungi was observed in drying (78.4 % ± 13.6) and storage (70.3 % ± 3.2) steps of cocoa samples from farm A. In farm B, the wash step of cocoa beans after fermentation reduced pulp residues and consequently the OTA-producing fungi infection during drying (12.7 % ± 5.8) and storage (37 % ± 10.4) steps were diminished. The main OTA-producing strain isolated from Malt Extract Agar (MEA) growth medium was Aspergillus carbonarius (14307.5 µg/kg). The presence of ochratoxigenic species was correlated to high levels of OTA measured in cocoa beans during storage in both farm A and B (304.6 ± 15.3 and 11.3 ± 0.5 µg/kg, respectively), and in fresh cocoa beans from farm B (22.2 ± 3.5 µg/kg). This study reports for the first time OTA content and ochratoxigenic species during cocoa process in Mexico. This allowed the identification and evaluation of the sanitary risks linked to Mexican cocoa production.
Development instrument science process skills biology for Junior High School

Article Information ABSTRACT Submitted: 2020-08-15 Accepted: 2021-06-10 Published: 2021-06-10 Science process skills (SPS) are basic skills in science and tools of a scientist to investigate science phenomena. One of the ways to improve science process skills is by giving students practice questions. This study aims to develop a valid and reliable science process skills instrument. The research is developmental research using a procedural model adapted from Djaali and Muljono. These steps include the theory synthesis stage, the design stage (variable construction, development of question indicators, preparation of grids, making instruments, scoring), and the evaluation stage (validity test, reliability test, and item analysis). The research instruments used were expert validation sheets, practitioner assessment questionnaires, and product trial questions for 100 students. The results of judgment expert and practitioner judgment were processed descriptively. The empirical validity results, which are quantitative data, are processed using the software Microsoft Excel. The results showed that the developed questions were valid based on logical validity (89.43%) and empirical validity (84%). The reliability calculation shows the high category (0.66). This study concludes that the SPS questions developed are feasible to assess the process skills of biology subjects at the junior high school level.
Origin of the Co‐Seismic Variations of Elastic Properties in the Crust: Insight From the Laboratory

Seismological observations highlighted that earthquakes are often followed by changes in elastic properties around the fault zone. Here, we studied the origin of these variations using stick‐slip experiments on saw‐cut granite samples presenting different degrees of bulk damage (i.e., microcracks). Stick‐slip events were induced under triaxial compression configuration with continuous active ultrasonic measurements at confining pressures representative of upper crustal conditions (15–120 MPa). Both the P‐wave velocity ( VP ) and amplitude ( AP ) showed drops, concurrently with stress drops, and had a non‐monotonic dependence toward the fault's stress state. Our experimental results suggest that co‐seismic changes in VP were mostly controlled by the elastic re‐opening of microcracks in the bulk, rather than by co‐seismic damage or the formation of fault gouge. Co‐seismic changes in AP were controlled by a combination of elastic re‐opening of microcracks in the bulk and inelastic processes (i.e., co‐seismic damage and gouge formation and dilation).
A finite-element discretization of some boundary value problems for nonlinear strain-limiting elastic bodies

It is well known that the linearized theory of elasticity admits the logically inconsistent solution of singular strains when applied to certain naive models of fracture while the theory is a first-order approximation to finite elasticity in the asymptotic limit of infinitesimal displacement gradient. Meanwhile, the strain-limiting models, a special subclass of nonlinear implicit constitutive relations, predict uniformly bounded strain in the whole material body including at the strain-concentrator such as a crack tip or reentrant corner. Such a nonlinear approximation cannot be possible within the standard linearization procedure of either Cauchy or Green elasticity. In this work, we examine a finite-element discretization for several boundary value problems to study the state of stress–strain in the solid body of which response is described by a nonlinear strain-limiting theory of elasticity. The problems of notches, oriented cracks, and an interface crack in anti-plane shear are analyzed. The numerical results indicate that the linearized strain remains below a value that can be fixed a priori, therefore, ensuring the validity of the nonlinear model. In addition, we find high stress values in the neighborhood of the crack tip in every example, thereby suggesting that the crack tip acts as a singular energy sink for a stationary crack. We also calculate the stress intensity factor (SIF) in this study. The computed value of SIF in the nonlinear strain-limiting model is corresponding to that of the classical linear model, and thereby providing a tenet for a possible local criterion for fracture. The framework of strain-limiting theories, within which the linearized strain bears a nonlinear relationship with the stress, can provide a rational basis for developing physically meaningful models to study a crack evolution in elastic solids.
A Preliminary Investigation of Teacher-Reported Classroom-Level Adversity and Teacher–Student Interactions

Early elementary-age students with and at risk of emotional and behavioral disorders (EBD) tend to develop negative interaction patterns with their teachers. This preliminary study examines the extent to which symptoms of teacher burnout and teacher reports of classroom adversity are associated with the likelihood of negative interactions between teachers and students with and at risk of EBD. We conducted observations to assess teacher–student interactions in individual and group settings, and teachers reported on burnout and classroom adversity. This study included 10 teachers and 15 of their students with or at risk of EBD. High levels of classroom adversity increased the likelihood of negative teacher–student individual interaction. High levels of classroom adversity modified the relation between personal accomplishment and negative teacher–student interactions in group settings. Findings suggest teachers may need additional support for engaging in high-quality interactions with students with and at risk of EBD, particularly in classrooms facing high levels of adversity, and inform intervention design and implementation.
Plant naturalization trends reflect socioeconomic history and show a high likelihood of inter-island spread in Hawai‘i

Abstract The composition of nonnative floras is influenced by a region's socioeconomic history, yet rarely are these factors studied alongside plant naturalization rates over time. Such information is especially critical for archipelagos, which often host large numbers of nonnative plants and would benefit from prevention of inter-island spread. We compiled the first record of occurrence and first record of naturalization for all naturalized plants in Hawai‘i alongside data on their origin, native climate types, taxonomy, and likely introduction pathway and compared rates of naturalization with socioeconomic trends. We found that the rate of total plant naturalizations has increased at a roughly constant rate during the past century without any sign of plateauing. However, this relatively steady increase is underlain by notable fluctuations in naturalization rates for different introduction pathways, with ornamentals increasing recently, while agriculture-related plants have decreased. Furthermore, this trend mirrors a shift from an agriculture-dominated economy to a tourism-based one associated with increases in both resident and tourist populations as well as general economic well-being. We further found that the average naturalized species spreads at a rate of 1.86 islands per decade, eventually occupying most major islands in the archipelago, and the rate of spread appears to be increasing since Hawai‘i’s economic shift. Our findings also emphasize the diversity of Hawai‘i’s nonnative flora, which originates from a variety of climates, continents, and taxonomic groups. We demonstrated that many nonnative species have native ranges that include temperate climates, which is important, because these climates typically co-occur with higher-elevation, remnant patches of native-dominated ecosystems in Hawai‘i. This study reveals trends that may help predict a species’ ability to naturalize and spread within and between islands, and we discuss management implications that may be extended to other regions.
Microstructures in a shear margin: Jarvis Glacier, Alaska

Abstract Microstructures, including crystallographic fabric, within the margin of streaming ice can exert strong control on flow dynamics. To characterize a natural setting, we retrieved three cores, two of which reached bed, from the flank of Jarvis Glacier, eastern Alaska Range, Alaska. The core sites lie ~1 km downstream of the source, with abundant water present in the extracted cores and at the base of the glacier. All cores exhibit dipping layers, a combination of debris bands and bubble-free domains. Grain sizes coarsen on average approaching the lateral margin. Crystallographic orientations are more clustered and with c-axes closer to horizontal nearer the lateral margin. The measured fabric is sufficiently weak to induce little mechanical anisotropy, but the data suggest that despite the challenging conditions of warm ice, abundant water and a short flow distance, many aspects of the microstructure, including measurable crystallographic fabric, evolved in systematic ways.
Towards a Conceptual Development of Industry 4.0, Servitisation, and Circular Economy: A Systematic Literature Review

Industry 4.0 (I4.0) technologies have been highlighted in recent literature as enablers of servitisation. Simultaneously, businesses are advised to implement a circular economy (CE) to bring new opportunities. However, it is pertinent to mention that little attention has been given to assess the role of I4.0 in adopting the CE and servitisation in a fully integrated manner. This research fills this gap by developing a conceptual framework through a systematic literature review of 139 studies investigating the relationship between the I4.0, CE, and servitisation. This study identifies the impact of these variables on a firm’s operational and financial performance (revenue stream, growth, and profitability). Our research findings advocate that adopting I4.0 technologies to the business and manufacturing model enables sustainability, energy and resource efficiency while enhancing performance and offering innovative products through smart services. Thus, firms must systematically adopt I4.0 technologies to support a CE model that creates value through servitisation. This study identifies the research gaps that are unexplored for practitioners and future researchers while providing insight into the role of I4.0 in implementing CE in the servitisation business model.
The Factors Affecting the Physical Activity of the Health Care Workers of Iran University of Medical Sciences: A Qualitative Study

Background: The low physical activity is a challenge in adults. A majority of adults spend many hours each week at work, so the workplace is a suitable site for health promotion and implementation of physical activity programs. This qualitative study was implemented to identify worksite physical activity barriers and facilitators from the perspective of the employees of the Iran University of Medical Science. Methods: In the present qualitative content analysis, five focus group discussions were held with the participation of 68 personnel of Iran University of Medical Sciences. Purposive sampling with maximum diversity was carried out for the study. Results: The analysis of the data led to the identification of three general themes, including challenges and barriers, strategies, and incentives (facilitators). The four main categories of challenges and barriers included policy-making and legislation, organizational factors, structural factors, and personal factors. Most barriers identified by the participants were placed in the personal factors and organizational factors categories. The strategies for increasing physical activity were identified in the following three categories: Policy-making and legislation, organizational factors, and environmental factors. The majority of the strategies proposed were placed in the organizational factors and policy-making and legislation categories.Conclusions: Increasing physical activity in the workplace as a strategy for the general promotion of physical activity in people requires interventions in different areas, especially with regard to organizational factors and policy-making and legislation.
Transition policies for climatically sustainable aviation

ABSTRACT Emissions from aviation are expected to grow. With evidence that the International Civil Aviation Organization’s Carbon Offsetting and Reduction Scheme for International Aviation is an inadequate mitigation mechanism, there is interest in upscaling the sector’s climate-related policies. This paper reviews potential aviation emissions mitigation policies against the background of emerging complexities, such as the large share of radiative forcing not covered under any policy agreement, as well as highly skewed demand distributions. In total, 30 voluntary, market-based and regulatory “transition policies” are identified and evaluated with regard to their potential to reduce emissions from air passenger transport and to initiate the transition to new fuels and propulsion technologies. The paper also discusses the potential public acceptance of differing policies. It concludes that the removal of fossil fuel and related subsidies represents a priority, supported by policy mixes comprising levies (CO2, frequent fliers, premium classes) and a feed-in quota for definitively established sustainable aviation fuels. To reduce flight emissions is feasible in principle, but will require policy initiatives at the national level or at the level of regional jurisdictions such as the European Union.
Rural Community-Perceived Benefits of a Music Festival

There is a general consensus that tourism activity must have the support of a local community in order to build sustainable tourism development. Among the competitive Romanian tourism products, festival tourism should be mentioned, even though it is relatively new. Therefore, given the traditional communities from rural areas which are confronted with an international flux of tourists, it is vital to analyze the perception of and support for festivals. The presumption is that if there are benefits for the locals, support increases. In order to achieve the objective of the study, research has been conducted among the local rural community of Bontida, which is the location of an international annual music festival. The instrument used was a questionnaire which had four parts that aimed to measure the cultural benefits and costs of the festival and the sense of well-being of the community, given the fact that previous studies focused mainly on the economic and environmental impacts, but not so much on the socio-cultural dimensions. Descriptive statistics were used to analyze the data. The results indicated that the benefits are greater than the perceived costs, a fact which is encouraging from the perspective of developing a sustainable tourism strategy, both by the local authorities and private stakeholders.
Friendly or unfriendly confines: impact of Chicago baseball stadia on vicinity crime patterns

ABSTRACT Rationale/Purpose: The purpose of this paper is to explore the impact of the two Major League Baseball stadia in Chicago, Wrigley Field and Guaranteed Rate Field (GRF) on stadium vicinity crime to assess changes in crime pattern on game day. Design/methodology/approach: This study compares the impact of stadia location on crime while employing an analysis on radii and concentric bands around baseball stadia in Chicago. An analysis of the influences of factors on crime counts within a 3-km radius of baseball stadia in Chicago from 2015 to 2017. Findings: The analysis suggested significant differences in crime pattern due to the presence of baseball stadia; more crime closer to Wrigley, in general, but more crime in the further areas of interest near GRF. Practical Implications: : The findings demonstrate how venues may influence crime patterns in a city including evidence of a displacement effect of crime further away from GRF while crime clusters closer around Wrigley Field. Research Contribution: This shows the need for different policing, crowd, risk, and communication strategies for different venues within the same city. Furthermore, the study confirms the importance of considering the impact of sporting events beyond the immediate vicinity of the venue property.
