Hundreds enrolled the online institute, where technologies (e.g., Zoom, Canvas, Google Docs, etc.) facilitated interactions among participants and preserved their ideas and perspectives throughout the program. Using a grounded theory analysis approach attentive to the participants’ words, the authors uncovered participants’ experiences and their perspectives on the structures that shaped those experiences. The data ultimately revealed five themes (pedagogical knowledge; student perspective; community and connection; technology; emotion) that relate to changes in participant attitudes, perceptions, and/or pedagogical approaches. Drawing on these themes, we identify implications for future professional development programing design that align with other results from the literature, including the importance of modeling the student experience, deliberately addressing community and connection, building in time for synthesis and commitment, and prompting faculty to identify and reflect on their emotions. Though some of the identified themes may have been more visible because data were captured in the first year of the COVID-19 pandemic, these themes are aligned with prior research and existing learning theories and will apply to the design of course design institutes beyond the context of crisis situations.

The quality of wine products is directly influenced by the quality of the grapes, their process technology, the care and the quality of the premises and equipment used, as well as the conditions for the storage and use of the wines. In most red wine-making processes, it is preferred that the maceration process is accompanied by the fermentation process, as increase in the alcohol content favours the intensification of the extraction process. For this reason, both processes are combined in a single technological operation known as maceration-fermentation. The largest amount of polyphenolic compounds of wine, anthocyanins and tannins comes from the solid parts of the grapes - the skins and seeds, and these have a decisive influence on the phenolic character of wines. Maceration is a fractional extraction which leads to the dissolution of the useful components of the grapes, which give the flavour, colour and taste typical of red wine. The aim of this research was to analyse the effect of different techniques of maceration fermentation on the phenolic composition of red wines obtained from Merlot, Pinot noir and Cabernet Sauvignon grape varieties in Copou-Iasi vineyard compared to red wines obtained from the same varieties in Murfaltar vineyard, located in the northeast and south of Romania, respectively. Wines obtained by maceration-fermentation in rotating tanks have higher values of the Folin-Ciocâlteu index (wines obtained from Pinot noir) in contrast to those obtained by the classical maceration-fermentation technique (wines obtained from Merlot and Cabernet Sauvignon).","PeriodicalId":74859,"journal":{"name":"Spring simulation conference (SpringSim)","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80782803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are an estimated 18 million palm trees in Algeria with more than 1000 cultivars. This poorly known resource is unfortunately threatened with extinction. This work was carried out on 24 date palm cultivars, studying their morphological and physicochemical characteristics, such as the weight, length and diameter of the date and the seed, and the consistency, moisture, pH and sugar content of the dates. Ten homogeneous palm trees were selected for each cultivar.\u0000From each tree, we collected 40 fruits devoid of their calices (4-5 fruits per bunch), at different heights and orientations in each bunch. The results show that the morphological and physicochemical characteristics vary from one cultivar to another. The dates of most cultivars have a combination of good and bad characteristics. The cultivar Tmar-Bousbaa has very high values for the characteristics weight, length, and diameter of the date and seed (23.16 g, 4.90 cm, 2.85 cm, and 1.53 g, 2.74 cm, 0.94 cm, respectively). The cultivars Takarnait and Halwa have high acidity, varying between 1.08 and 1.92 g/kg of fresh material and a pH of less than 5.46.\u0000The cultivar Bouarous has a low sugar content: less than 63%. Principal component analysis (PCA) was used to analyse the whole dataset, revealing high variability among the cultivars. Thus, out of 14 characteristics investigated, ten have been shown to be strong discriminating factors.","PeriodicalId":74859,"journal":{"name":"Spring simulation conference (SpringSim)","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88172335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, the conventional method of vegetative propagation by cuttings is associated with difficulties in rooting. Hence, for the first time, this study describes an efficient and reproducible in vitro protocol for breaking the dormancy of seeds from the endangered forest tree T. baccata L. via zygotic embryo culture. Embryos isolated from 100% sterile seeds were cultured on DCR medium that contains sucrose (30 g/l), agar (8 g/l), and activated charcoal (5 g/l), fortified with different concentrations of Plant Growth Regulators (PGRs), and held at a temperature of 25 ± 2 ºC in a growth room. The results revealed that the in vitro embryo germination percentage was mostly affected by gibberellic acid (GA3) and thidiazuron (TDZ). Among the nine treatments, the treatments with 0.5 mg/l TDZ and 1 mg/l GA3 showed the highest germination (100%), while the other treatments all increased the germination percentages significantly compared to the control (37.5%). The 1/2 DCR medium with the addition of 0.1 mg/l indole-3-butyric acid (IBA) resulted in the highest rooting ratio (94%). However, the greatest root and hypocotyl elongation (59.37 ± 3.77 and 62.75 ± 4.43 mm, respectively) occurred when seedlings were cultured on 1/2 DCR medium containing 0.5 mg/l BA. Plantlets were transplanted into plastic pots containing an autoclaved garden soil, sand, and vermiculite mixture (1:1:1) and held at a temperature of 25 ± 2 ºC in a growth room for 4 weeks before being transplanted into the greenhouse. These results indicated that the protocol developed during the current study will be useful to overcome seed dormancy and for multiplication and conservation of the species T. baccata L.","PeriodicalId":74859,"journal":{"name":"Spring simulation conference (SpringSim)","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81234855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the current paper was a comparative characterisation in terms of crude chemical composition, Ca and P, heavy metals (Pb, Cd, Zn, Cu), nitrates, nitrites and pesticides, for the natural meadow and green alfalfa, cultivated in ecological and conventional systems, utilised for feeding dairy cows. Sampling and analysis were performed according to established standards and working methods: drying for dry matter (DM); calcination for crude ash (C Ash); Kjeldahl method for crude protein (CP); Soxhlet method for crude fat or ether extract (EE), spectrophotometry for P, nitrates and nitrites; atomic absorption spectrometry for Ca, Pb, Cd, Cu and Zn; gas-chromatography for pesticides. For alfalfa, the highest values in the ecological system were for C Ash (12.68%), EE (2.50%), NFE (35.78%) and Ca (1.79%). For the natural meadow, the highest values in the ecological system were for DM (25.72%), OS (89.32%), EE (2.76%), NFE (45.27%) and Ca (0.70%). The toxic heavy metal content was below the limits allowed (1 mg/kg Cd and 30 mg/kg Pb). For Pb the values determined from the two feeds were between 0.06 mg/kg and 0.16 mg/kg and for Cd between 0.007 mg/kg and 0.02 mg/kg. The pesticides residuum was under the detection limit of 0.05 mg/kg DM for organo-chlorinated pesticides and 0.001 mg/kg for organo-phosphoric pesticides. All the studied forages were safe regarding pollutants (heavy metals, nitrites, nitrates and pesticides), but statistical differences existed between the production systems, such that the ecological system seems to be better.","PeriodicalId":74859,"journal":{"name":"Spring simulation conference (SpringSim)","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74531082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A combined analysis with a factorial layout in the two years of 2016 and 2017 with five replications was used to evaluate the yield and yield components of triticale under different methanol concentrations and irrigation managements in Isfahan, Iran. Irrigation treatments consisted of irrigation on the basis of 70%, 80%, 90% and 100% crop water requirements, and methanol treatments as foliar application on the basis of 15% methanol concentration, 30% methanol concentration and control treatment (0%). Methanol application influence on one hundred grain weight was significant. The maximum plant height, number of tillers, Leaf area index (LAI), leaf area duration (LAD), one hundred grain weight, grain yield, biological yield, harvest index and protein content were achieved in irrigation on the basis of 100% crop water requirement. The maximum plant height, number of tillers, LAI, LAD, one hundred grain weight, grain yield, biological yield, harvest index and protein were obtained in 2017. Foliar methanol application with 15% concentration obtained the maximum plant height, LAI, LAD, one hundred grain weight, biological yield, soil plant analytical development (SPAD) and protein percentage. The results of this experiment suggest that methanol can aid in alleviating the effects of drought stress on triticale in the climatic condition of Isfahan. It is concluded that triticale cultivars performed better in 2017, with 15% concentration of methanol application and irrigation on the basis of 100% crop water requirement.","PeriodicalId":74859,"journal":{"name":"Spring simulation conference (SpringSim)","volume":"24 1","pages":"100-110"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82811848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
