Tourism is one of the most important sectors of the economy of a country, but any event with negative connotations such as the appearance of epidemics, terrorist attacks, economic or social instability influences the activity in this sector. In the context of the current crisis triggered by the onset of coronavirus (COVID - 19) and based on past experiences, in this paper we intend to analyse how in the last 20 years, different epidemics have contributed to reducing tourism in the affected areas and to economic losses important. The paper tests by empirical analyses based on the data published in different international databases, as well as by a quantitative analysis how the appearance of epidemics influences the tourism in both the affected areas, as well as worldwide.

The article presents the results of research carried out in 2013 - 2017 in the conditions of the experimental field of the Mykolayiv National Agrarian University in southern chernozem to study the efficiency of the treatment of barley crops with modern growth-regulating preparations in the background of mineral fertilizers. The influence of variety (Adapt, Stalker, Aeneas) and ferilization (N30P30, Urea K1, Urea K2, Escort-bio, Organic D2) of barley plants on the formation of elements of the crop structure (total number of stemsand productive stems, number of grains in the ear and weight of grain from one ear) and the level of grain yield were investigated. It was determined that the application of preseeding cultivation of spring barley with mineral fertilizer at a dose of N30P30 (background) and the application of extra-root cropping at the beginning of the phases of stooling and the earing with fertilizers Urea K1, Urea K2,Organic D2 and Escort-bio created favorable conditions for the formation of optimal grain yield levels. It was determined that the highest yield of barley grain was formed in experimental variants using Organic D2 (3.22-3.56 t ha-1) and Escort-bio (3.25-3.61 t ha-1), depending on the variety. These exceeded the yield rate on an unfertilized plot by 20.5-21.3 and 21.2- 22.4% for Organic D2 and Escort-bio, respectively, and with the application of mineral fertilizers only, the yield rate grew by 12.0-13.5%. The highest yield of grain was formed by plants of the Aeneas’s variety: 2.80-3.61 t ha-1, depending on the variants of nourishment.

This study describes a prospective, randomized, blinded clinical study on 118 cats which required chemical restraint. The protocol of sedation was based on a combination of alfaxalone and an opioid among methadone, butorphanol and pethidine in order to improve the quality of sedation, offset the lack of analgesia and reduce side effects of alfaxalone. The patients underwent clinical evaluation and each of them was randomly allocated to one of the 3 groups. The evaluation procedure lasted 30 minutes from sedation, during which cats were monitored to fill an evaluation sheet at predefined time points. The quality of recovery was influenced by the opioid, with a higher score for butorphanol and pethidine, but also by body condition score (BCS) and age. The time of lateral recumbency was affected by the American Society of Anesthesiologists score (ASA), and it was higher in ASA 1-2. Physiological parameters were influenced by the molecule over time. The molecules influenced also the degree of muscular relaxation and quality of sedation. The last parameter was also influenced by ASA status with a greater score in cats classified as ASA 3.

Sorghum flour is a valuable ingredient for breadmaking. The thermo-mechanical properties of dough prepared out of wheat flour supplemented with 10, 20, 30, 40 and 50% sorghum flour and the bread characteristics in terms of specific volume, crumb firmness, resistant starch, total phenols and antioxidant activity were investigated. Water absorption and dough stability decreased when increasing the level of sorghum flour as a consequence of the dilution effect of gluten. Starch gelatinization speed was 0.50 Nm/min in case of wheat flour and increased up to 0.70 Nm/min for sample with 50% sorghum flour. In addition, gel stability during heating increased with the level of sorghum flour. Although wheat flour substitution by sorghum flour affected the specific volume of the bread and crumb firmness, the level of biologically active compounds in the final products was significantly increased. In particular, the addition of 50% sorghum flour caused the increase of the total phenols content and DPPH-RSA of bread from 122.41 to 527.59 μmol FAE/g d.w., and from 3.90 to 25.59%, respectively. Moreover, the content of resistant starch of the breads increased with the level of sorghum flour, most probably as a consequence of the presence of polyphenols from sorghum flour and of the interaction between sorghum starch and proteins.

Traditional culture system (TCS) in open field is high demanding in water and other natural resources and thus has driven the development of protected cultivation systems with innovative horticultural growing techniques. Greenhouse systems and soilless culture system (SCS) can allow obtaining high yields and improving water use efficiency especially in marginal and arid regions. Desert areas have tapped the opportunity arising from technical innovation to create new chances for horticulture development with important social and environmental impacts; today these advanced techniques can be successfully adopted in every context in which a high-water use efficiency is needed. Indoor and vertical farming represent new possible cultivation strategies for urban and peri-urban areas where the SCS plays an important role. Integrated systems must be adopted for lowering the production costs such as the use of innovative lighting systems and ICT controlling units for real time management. In fact, the application of highly specialized growing techniques represents an efficient tool to increase sustainable agricultural productions, thanks to the interaction between growers, supply chain partners, research institutes and governmental agencies.

Agritourism represents a fast-growing industry in Romania, with an average growth rate of tourist arrivals four times higher than the sectorial one. However, there are strong regional differences in the flow of tourists attracted, whereas the ability of the specific destinations to attract tourism flows, given their endogenous characteristics, are insufficiently studied. The paper analyses tourist flows between 2007-2016 from the supply-side of tourist products perspective taking into consideration the particularities of tourism destination (natural resources, infrastructure, socio-demographic aspects etc.). The dependent variable in this study is the number of new overnight stays, as a proxy for the attractiveness of the region. The results of the binary logistic confirm the importance of tourism infrastructure variables, as well as natural environment and socio-demographic aspects in determining domestic tourism flows. Thus, the demographic elements such as population density, young women population rate, young working population rate can give an important comparative advantage to a tourism destination. Moreover, the study highlights the presence of other relevant determinants such as the area occupied with meadows and ponds, as elements of the natural environment.
