Farmland value in the “Conegliano Valdobbiadene Prosecco Superiore PGDO” area. An application of the Hedonic Pricing method.
Authors: Tempesta Tiziano , Foscolo Isabella , Nardin Nicola , Trentin Giorgio
Published: October 2021

In the last 30 years, numerous studies analysed the factors that affect land prices mainly using the Hedonic Pricing method. These studies have shown that many factors can affect land prices (e.g. land and surrounding territory characteristics, accessibility, proximity to urban area, etc.). However, they rarely addressed the analysis of the reliability of the models by comparing the estimated values to the observed one. Attempting to face this problem, our study analysed the land market of the “Conegliano Valdobbiadene Prosecco Superiore PGDO” area. Despite the quite high coefficient of determination (r2 = 0.76) and statistical significance of the model parameters, we found that the percentage absolute deviation between observed and estimated value is higher than 30% in 34% of cases. Our results seem to suggest that future researches should devote particular attention to the analysis of the discrepancies existing between estimated values and market prices in order to support the appraisal activity of professional valuers.

Published: October 2021

Several previous researches reported that there was a positive correlation between metacognitive skills and cognitive learning results. However, some others reported otherwise. This is believed to be related to the learning model used. This research aimed at revealing the correlation between metacognitive skills and cognitive learning results of pre-service teachers taught by using QASEE and RQA learning models, as well as by using conventional learning, and comparing the regression equations of the three learnings. 107 biology pre-service teachers at Universitas Islam Negeri Raden Fatah Palembang, Indonesia, were involved in this correlational study. Data were obtained by the essay test and were analyzed by simple linear regression analysis. The research result indicates that there is a significant correlation between metacognitive skills and cognitive learning results of the pre-service teachers taught by using the three learnings. It was also found that the regression equations uncovered at the three learnings was parallel and coincide. The contribution of metacognitive skills toward cognitive learning results uncovered in RQA learning model is the highest one among the three learnings preceded by that uncovered in QASEE learning model. This information is beneficial for lecturers in order to use the right learning model to empower pre-service teachers’ metacognitive skills and cognitive learning results.

Published: October 2021

Twenty-first century chemistry education researchers reported challenges in chemistry education pertaining to high school chemistry teaching-learning outcomes. Even though all studies intended to improve chemistry teaching-learning outcomes, unfortunately the impact of chemistry education research found not to be much encouraging. A few of these studies were compared to identify a possible missing link which is to be addressed under present context of chemistry education research (CER). The issue of students’ attitude, perception and a link of performance in chemistry with attitude and perception drew the attention and found to be missing in the present CER studies. The need to address the issue within the context of existing school environment was felt. This communication is prepared based on an analysis of students’ performance of eleventh grade students from a rural school of South Africa in a chemistry endof- year test.

This research is motivated by the lack of understanding of students' mathematical concepts in mathematics which is caused by a lack of motivation to learn in students and the lack of material connection with everyday life. Mathematics learning really needs to be learned by students because Mathematics has an important purpose to meet practical needs related to the development of students' abilities to use mathematics in everyday life, such as counting which is often experienced by students and can develop the ability to calculate weight. and content. Although Mathematics is considered important to learn, not a few students feel that Mathematics is difficult to master, so it is considered boring and makes students' interest in learning in Mathematics considered low. Based on the PISA annual study survey, the Indonesian Mathematics competency has decreased from 386 points in 2015 to 379 points in 2018 with an OECD average of 489. The benefits of studying Mathematics are used to make transactions in trade. One way to make mathematics more understandable is to use the Realistic Mathematics Education (RME) approach so that students can learn more realistically. The purpose of this study was to determine the increase in students' understanding of mathematical concepts using the Realistic Mathematics Education (RME) approach and whether there were changes that occurred after the treatment using this approach. This research was conducted with quantitative research methods and the research design of One Groups Pretest-Posttest Design.

Published: October 2021

The effect of mold conditions was investigated in terms of mold temperature (30oC and 90oC) and cooling time (30 s and 60 s) on the heat resistance of injection-molded bars for stereocomplex polylactide-b-polyethylene glycol-b-polylactide (scPLA-PEG-PLA). Comparative study was performed for poly(L-lactide) (PLLA) and PLLA-b-PEG-b-PLLA (PLLA-PEG-PLLA). scPLA-PEG-PLA was 90/10 (w/w) PLLA-PEG-PLLA/poly(D-lactide) blend. scPLA-PEG-PLA exhibited the easiest crystallization upon cooling scan as shown by differential scanning calorimetry (DSC). Higher mold-temperature and longer cooling-time induced higher degree of crystallinity as assessed by X-ray diffractometry (XRD) except for PLLA bars. The heat resistance of both PLLA-PEG-PLLA and scPLA-PEG-PLA bars was improved with increased mold-temperature and cooling-time as shown by dynamic mechanical analysis (DMA), vicat softening temperature (VST) and heat distortion-resistance tests except for PLLA bars. In conclusion, the heat resistance of injection-molded bars prepared at 90˚C mold temperature was in the order scPLA-PEG-PLA ] PLLA-PEG-PLLA ] PLLA. The results suggested that flexible PLLA-PEG-PLLA and scPLA-PEG-PLA with high degrees of crystallinity were successfully obtained by injection molding for use as good heat-resistant bioplastic products.

Published: October 2021

Great interest has been shown lately in bio-composite materials because they are inexpensive and sustainable. Composites with matrices and natural reinforcers have been little studied. Here, we study certain mechanical properties of composite materials with a Dammar-based matrix (also named hybrid matrix) and flax fabric reinforcement. To be precise, we examine three types of resins where Dammar is the major component, with a volume proportion of 55%, 65% and 75%. In this respect, we have made composite materials reinforced by two types of flax fabric and we have measured the characteristic curves and some mechanical properties, such as the Young�s modulus, tensile strength and elongation at break using tensile tests. Based on the obtained properties, it is proposed or possible to use these materials in orthopedics.

The number of surgical procedures for abdominal wall defects is increasing, often requiring the insertion of plastic material meshes. Surveillance of patients with inserted plastic meshes requires an accurate determination of the position of the mesh. However, this is a difficult task, depending on the kind of mesh, magnetic resonance imaging (MRI) protocol or consistence of the surrounding tissue (fat, muscle, aponeurosis). The aim of our research was to develop an experimental model to test the ability of MRI to identify the exact position of surgical plastic meshes: polypropylene or polyester. To simulate the placement of a mesh in human body we developed a model built up from two pieces of tissue with dimensions of 40 cm x 20 cm, harvested from a pig with a weight of 120 kg. The meshes were situated for MRI evaluation between the two pieces: abdominal pig muscle respectively suprajacent abdominal pig wall subcutaneous fat, approximately 2 cm high. Five surgical meshes were scanned through six MRI sequences, in view of establishing an optimal MRI scanning protocol and best visible meshes. The MRI scans were evaluated by 5 radiologists with different degrees of training. Our results showed that the experimental model developed by us can be successfully used to test the ability of MRI to visualize different kind of plastic meshes. Also, our experiment has revealed that T1fl2D sequence is the best in highlighting meshes from surrounding tissue, and the best visualized Mesh was number 4, made of polyester. In conclusion, based on our experimental model, we should select a plastic mesh or MRI protocol which will allow an optimal post implantation monitoring. Modern technology of material�s fabrication can help to better identify the mesh itself using MRI scanning.

Published: October 2021

The research was conducted by a member of the 60th Russian Antarctic Expedition at the all-yearround Mirny Station. The aim was to study what influence contact intensity with the outside environment has on adaptive capabilities of polar station staff. The level of adaptive capabilities was evaluated using the method of cardio-respiratory synchronism, assessing the index of regulatory and adaptive status (IRAS). This method had been developed at the Normal Physiology Department of Kuban State Medical University under the supervision of Prof. V.M. Pokrovsky. It is based on recording the synchronization parameters of controlled high respiratory rate and heart rate. We compared IRAS dynamics of two aerologists during one year of wintering. The subjects had similar anthropometric data, health status and working conditions, the same length of Antarctic wintering (6 years) and were in the same age group. Contact intensity with the outside environment was determined by varying periods spent outside the station premises, mostly due to the lay-out of the residential and amenity buildings (canteen, leisure area, medical unit, gym). This period ranged from 2 to 7 hours on different days. The negative IRAS dynamics, being a marker of human adaptive capabilities, allowed us to identify the relationship between the intensity of environmental influence and the level of the body’s adaptive abilities in one of the expedition members who had been exposed to stronger environmental effects. The authors conclude that proper organization of off-duty periods aimed to decrease the influence of the outside environment will contribute to improving the health of the station staff and optimize their living conditions.

The purpose of this paper was to compare the physiological parameters of the cardiorespiratory system at rest and during the bicycle ergometer test to exhaustion in biathletes and cross-country skiers to identify the difference in the aerobic performance of athletes of two closely related winter sports. Materials and methods: 18 biathletes and 28 male cross-country skiers aged 17–21 years, all with the rank of the Candidate for Master of Sport, were examined. Bicycle ergometer testing to exhaustion was used (Oxycon Pro, Germany), cardiorespiratory parameters were analysed, maximal oxygen consumption (VO2 max) was determined, and the physiological cost of a unit of work was calculated. Results. At rest, a statistically significantly higher level of fitness was revealed in crosscountry skiers compared with biathletes according to such haemodynamic parameters as systolic blood pressure, pulse pressure, and double product. At maximal load, an increased degree of fitness was found in cross-country skiers in terms of power and duration of bicycle ergometer exercise, cardiac and pulse cost per unit of work, as well as gross and specific VO2 max. The body of cross-country skiers under the test to exhaustion (according to oxygen pulse value) functions more efficiently than the body of biathletes. Thus, higher level of fitness among cross-country skiers of the Komi Republic is manifested in the economization of cardiorespiratory functions both at rest and at maximal ergometric loads, as well as in the value of specific physiological cost per unit of work. Increased functionality (or reserves) of cross-country skiers is indicated by such parameters as systolic blood pressure, pulse pressure, double product, respiratory minute volume, oxygen consumption, and energy expenditure. It can be assumed that the aerobic performance of biathletes is lower than that of cross-country skiers as the former receive less training in cross-country skiing.

The question of studying changes in the immune responses of mother and foetus against the background of infections acquired via various routes remains relevant. This study aimed to assess the state of T-cell immunity and cytokine balance in pregnant women with various pathways of intrauterine infection and the condition of newborns. The study involved 205 pregnant women at high risk for intrauterine infection. In the 1st trimester, bacteriological and DNA analysis of the lower urogenital tract and cytological examination of the cervical canal were performed, blood levels of immunoglobulins M and G for herpes simplex virus type 1 and 2, cytomegalovirus infection, toxoplasmosis, and rubella were determined. In the whole blood of the women, lymphocyte immunophenotyping was performed using CYTO-STAT® triCHROMETM CD8-FITC/CD4-RD1/CD3-FITC monoclonal antibodies; the content of cytokines (IL-6, IL-10) was analysed by means of enzyme-linked immunosorbent assay. After delivery, a pathomorphological examination of the placenta was performed in line with the generally accepted method. According to the results of the study, the following groups of women were identified: 1) without infectious or inflammatory changes (n = 59); 2) with confirmed ascending infection (n = 69); 3) with haematogenous infection (n = 33); 4) with mixed infection (n = 44). The condition of newborns was assessed with the help of laboratory and instrumental methods, using the INTERGROWTH-21st charts and the Apgar score. We found that the functioning of the immune system of pregnant women is affected by viral infections acquired via the haematogenous route, resulting in a relative increase in suppressor T cells and a decrease in helper T cells, as well as ina growing absolute number of lymphocytes in the blood. The identified inhibition of IL-6 and IL-10 production in the groups with signs of placental lesions due to infection at 16–18 weeks can indicate a strain on the immune processes and development of placental insufficiency. Newborns with morphological signs of haematogenous infection are characterized by changes in the cytological parameters of residual cord blood, signs of placental insufficiency, low birth weight, and hypoxic-ischemic damage to the central nervous system.

Damage to the tendon-ligamentous apparatus places serious limitations on a personʼs physical activity. Injuries are especially common in physically healthy people leading an active lifestyle, such as athletes. To treat such injuries in orthopaedics and traumatology, autoplastic operations are performed or prostheses made of synthetic or biological materials are installed. The known treatment methods, in spite of their effectiveness, have a number of serious drawbacks, which often limit their use. Therefore, the search for new approaches and materials for plastic ligaments is an urgent task. Today, biotissue prostheses are accumulating advantages over their synthetic counterparts. The most promising raw material for biological ligament prostheses, due to its availability in the required quantity and optimal size, is the flexor and extensor calf tendons. This paper aimed to develop a method for treating xenogenic tendon to manufacture ligament prostheses and assessing its biocompatibility in a heterotopic implantation model. To manufacture a ligament prosthesis, the raw material was subjected to mechanical cleaning and chemical-physical treatment, as well as treatment with supercritical carbon dioxide fluid with the addition of the nonionic surfactant Tween 80, which together contributed to effective decellularization and removal of other biologically active components, while maintaining the physical and mechanical parameters and natural fiberarchitectonics of native raw materials. The biocompatible properties of ligament prosthesis specimens made from the flexor and extensor calf tendons using this method were evaluated in a model of heterotopic implantation into the subcutaneous adipose tissue of rats. The results obtained confirm the promising use of this material, treated according to the proposed method, in clinical practice.

Wildfire smoke affects the health of the population of the entire planet and each year the situation is getting worse. Fire smoke has mutagenic, carcinogenic and other long-term effects. The aim of this paper was to study the genotoxic effect of wildfire smoke on male white rats and the transgenerational effect of wildfire smoke on their offspring. Smoke exposure simulation was performed on 40 male white rats in 200-litre exposure chambers. Forest litter, branches, fallen bark, and the upper layer of soil served as a combustible substrate. The exposure was carried out for 4 hours 5 days a week in the course of 4 weeks. Offspring of both sexes were obtained from the exposed animals and intact females. We analysed DNA fragmentation and global DNA methylation in the gonadal tissue and blood cells of the exposed animals immediately after the exposure and global DNA methylation in the blood cells of the offspring upon reaching sexual maturity. The research was performed using the comet assay with modifications to study global DNA methylation with MspI and HpaII restriction enzymes. The exposed animals showed an increased level of global DNA methylation in their blood cells. In male offspring, a decrease in the level of global DNA methylation in the blood cells was revealed, compared with the controls, while females showed no differences from the controls. The established facts of changes in global DNA methylation after exposure to wildfire smoke require further in-depth research, since the mechanism of the development of this phenomenon remains rather unclear.
