Effects on the Double Bounce Detection in Urban Areas Based on SAR Polarimetric Characteristics
Authors: Delgado Blasco José Manuel , Fitrzyk Magdalena , Patruno Jolanda , Ruiz-Armenteros Antonio Miguel , Marconcini Mattia
Published: April 2020

Synthetic Aperture Radar (SAR) polarimetric datasets are widely used in the detection and classification of urban areas. Most methods used today are based on the decomposition of fully polarimetric SAR data, which allows for the extraction of physical information about the nature of the medium and the application of proper classification methods. According to the theory, the main and predominant backscattering mechanism for buildings is double bounce. However, when analyzing urban environments, the observed predominant backscatter may differ from theory depending on many aspects. In this paper, we analyze fully polarimetric ALOS PALSAR data for various cities located on different continents, proving that the theory does not hold for most cases. There are many factors that have an impact on the detected backscatter mechanism, and the theoretical principle of predominant double bounce in urban areas can be met only under specific conditions. These factors are, among others, the orientation of the buildings, the dimensions of the streets, the type of construction (i.e., numerous planes on the roof), etc. This paper also mentions the canonical example of San Francisco, widely analyzed in the literature, as a case showing the impact of building deorientation on double bounce scattering. This area of interest is also discussed in terms of the impact of SAR data resolution on the detection of specific backscatter mechanisms. The findings of this work are very useful for increasing the awareness of the utilization of classification approaches where only pixels with double bounce backscatter mechanisms are classified as urban areas. Moreover, the article lists factors that should be taken into consideration when performing urban area detection based only on polarimetric data and standard algorithms, such as street and building orientation, building heights, and structures.

Authors: Cerreta Maria , Giovene di Girasole Eleonora , Poli Giuliano , Regalbuto Stefania
Published: April 2020

The city-port context involves a decisive reality for the economic development of territories and nations, capable of significantly influencing the conditions of well-being and quality of life, and of making the Circular City Model (CCM) operational, preserving and enhancing seas and marine resources in a sustainable way. This can be achieved through the construction of appropriate production and consumption models, with attention to relations with the urban and territorial system. This paper presents an adaptive decision-making process for Naples (Italy) commercial port’s development strategies, aimed at re-establishing a sustainable city-port relationship and making Circular Economy (CE) principles operative. The approach has aimed at implementing a CCM by operationalizing European recommendations provided within both the Sustainable Development Goals (SDGs) framework—specifically focusing on goals 9, 11 and 12—and the Maritime Spatial Planning European Directive 2014/89, to face conflicts about the overlapping areas of the city-port through multidimensional evaluations’ principles and tools. In this perspective, a four-step methodological framework has been structured applying a place-based approach with mixed evaluation methods, eliciting soft and hard knowledge domains, which have been expressed and assessed by a core set of Sustainability Indicators (SI), linked to SDGs. The contribution outcomes have been centred on the assessment of three design alternatives for the East Naples port and the development of a hybrid regeneration scenario consistent with CE and sustainability principles. The structured decision-making process has allowed us to test how an adaptive approach can expand the knowledge base underpinning policy design and decisions to achieve better outcomes and cultivate a broad civic and technical engagement, that can enhance the legitimacy and transparency of policies.
Assessing Sustainability Performance at the Farm Level: Examples from Greek Agricultural Systems
Authors: Tzouramani Irene , Mantziaris Stamatis , Karanikolas Pavlos
Published: April 2020

In recent years, farmers and policymakers have faced ample challenges and have struggled to support the sustainability of the agricultural sector. Sustainable agriculture encompasses multiple concepts, and its performance produces extensive debate about data requirements, appropriate indicators, evaluation methods, and tools. Under the European Union (EU) financed project FLINT (Farm Level Indicators for New Topics in policy evaluation), detailed data have been collected at the farm level to provide broader coverage of sustainability indicators on a wide range of relevant topics to facilitate the assessment of sustainability performance. The approach has been applied in a pilot network of representative farms at the EU level, considering the heterogeneity of the EU farming sector to provide data infrastructure with up to date information for sustainability indicators. This study aims to assess sustainability performance at the farm level in Greece. Representative and dominant agricultural systems, such as permanent crops, olive trees, arable crops, and livestock (sheep) farms, comprise the Greek sample. It uses the analytical hierarchy process (AHP) methodology and attempts to gain insights into the sustainability performance of agricultural systems. The outcome of the sustainability assessment reveals knowledge and develops support for strategic farm choices in order to support both farmers and policymakers towards more sustainable development plans. The results indicate that three typical Mediterranean farming systems, namely permanent crops, olive trees, and extensive livestock systems (sheep farms), are more sustainable in contrast to intensive and arable crop farms.
Considering Cultural Consonance in Trustworthiness of Online Hotel Reviews among Generation Y for Sustainable Tourism: An Extended TAM Model
Authors: Bae So Young , Han Ju Hyoung
Published: April 2020

This study aims to predict Generation Y customers’ acceptance of user-generated content (UGC) websites by integrating an extended technology acceptance model (TAM), trustworthiness of online reviews, and cultural consensus and cultural consonance theory. To collect data, a free listing method was first used to recognize our ad hoc domain, i.e., the factors that determine the trustworthiness of online hotel reviews among Generation Y in South Korea, from an emic perspective. Based on the free listing results from 39 individuals, an online survey was conducted with 273 samples using a self-administered questionnaire. Cultural consensus analysis was conducted to determine whether there is a shared cultural model in trustworthiness factors among participants, and cultural consonance values were calculated. Then, a structural equation modeling technique was used to estimate how the proposed model explains the collected data. Results indicate that an agreed-upon cultural model of trustworthiness of online hotel reviews exists among sample members. Cultural consonance of trustworthiness was found to constitute a significant antecedent of perceived ease of use and attitude towards websites in the extended TAM model. This study can contribute to predict Generation Y customers’ acceptance of UGC websites and offer meaningful implications for sustainable tourism management, particularly when cultural variables are considered.
Expanding the Scope of the Bicycle Level-of-Service Concept: A Review of the Literature
Authors: Kazemzadeh Khashayar , Laureshyn Aliaksei , Winslott Hiselius Lena , Ronchi Enrico
Published: April 2020

Research into the bicycle level-of-service (BLOS) has been extensively conducted over the last three decades. This research has mostly focused on user perceptions of comfort to provide guidance for decision-makers and planners. Segments and nodes were studied first, followed by a network evaluation. Besides these investigations, several variables have also been utilized to depict the users’ perspectives within the BLOS field, along with other cycling research domains that simultaneously scrutinized the users’ preferences. This review investigates the variables and indices employed in the BLOS area in relation to the field of bicycle flow and comfort research. Despite general agreement among existing BLOS variables and the adopted indices, several important research gaps remain to be filled. First, BLOS indices are often categorized based on transport components, while scarce attention has been paid to BLOS studies in trip-end facilities such as bicycle parking facilities. The importance of these facilities has been highlighted instead within research related to comfort. Second, the advantages of separated bike facilities have been proven in many studies; however, scarce research has addressed the challenges associated with them (e.g., the heterogeneity within those facilities due to the presence of electric bikes and electric scooters). This issue is clearly noticeable within the research regarding flow studies. Furthermore, network evaluation (in comparison to segment and node indices) has been studied to a lesser extent, whereas issues such as connectivity can be evaluated mainly through a holistic approach to the system. This study takes one step toward demonstrating the importance of the integration of similar research domains in the BLOS field to eliminate the aforementioned shortcomings.
Second-Hand Smoke Exposure Effects on Human Health: Evaluation of PM10 Concentrations in the External Areas of a University Campus
Authors: Torretta Vincenzo , Tolkou Athanasia , Katsoyiannis Ioannis , Schiavon Marco
Published: April 2020

Studies about the measurement of outdoor tobacco smoke (OTS) are limited to a few very recent studies. In many countries around the world, within public buildings, smoking is prohibited by law. However, these prohibitions often drive smokers to move to the border of the areas where smoking is forbidden, typically the entrances of buildings, in order to smoke. When many smokers stand outdoors near the entrances, a significant “wall” of smoke is generated. This condition exposes nonsmokers to smoke and contaminates the indoor environment too. Such a situation is amplified if the outdoor external area is covered. This paper presents a work carried out in a university campus, near building entrances, with the aim of studying the second-hand smoke (SHS) exposure in outdoor conditions. Measurements of particulate matter in specific environmental conditions are evaluated to estimate the OTS impacts on the students and the academic staff. The results showed that the exposure to tobacco can be very high and even comparable to values found when tests were carried out indoors, at the same distances from the smokers. A discussion about forbidding smoking near the entrances of public buildings is reported, including considerations about the environmental and public health concerns induced by SHS exposure and the smoking activity.
The Significance of Community Training Centers in Building Affordable Housing and Developing Settlements
Authors: Bredenoord Jan , Park Joon , Kim Kyohee
Published: April 2020

This paper examines the visions and the roles of community training centers (CTCs) in community development and housing provision in developing countries from the perspective of assisted self-help housing. It reviews a Korean community center that contributed to community-led self-help housing for low-income groups in the 1970s. It also reviews a few notable CTCs from India, Uganda, Nepal, and three countries in Central America to examine the functions and contributions of the CTCs. It was found that CTCs play a central role in community empowerment and the production of affordable building materials receiving technical or financial assistance from non-governmental organizations (NGOs) and governments. The paper makes a compelling case for CTCs by drawing on these exemplary cases to provide a development model that has the potential to facilitate the improvement of the living environment in developing countries.

Published: April 2020

RIG-I plays an essential role in the duck innate immune response to influenza infection. RIG-I engages the critical adaptor protein mitochondrial antiviral signaling (MAVS) to activate the downstream signaling pathway. The influenza A virus non-structural protein PB1-F2 interacts with MAVS in human cells to inhibit interferon production. As duck and human MAVS share only 28% amino acid similarity, it is not known whether the influenza virus can similarly inhibit MAVS signaling in avian cells. Using confocal microscopy we show that MAVS and the constitutively active N-terminal end of duck RIG-I (2CARD) co-localize in DF-1 cells, and duck MAVS is pulled down with GST-2CARD. We establish that either GST-2CARD, or duck MAVS can initiate innate signaling in chicken cells and their co-transfection augments interferon-beta promoter activity. Demonstrating the limits of cross-species interactions, duck RIG-I 2CARD initiates MAVS signaling in chicken cells, but works poorly in human cells. The D122A mutation of human 2CARD abrogates signaling by affecting MAVS engagement, and the reciprocal A120D mutation in duck 2CARD improves signaling in human cells. We show mitochondrial localization of PB1-F2 from influenza A virus strain A/Puerto Rico/8/1934 (H1N1; PR8), and its co-localization and co-immunoprecipitation with duck MAVS. PB1-F2 inhibits interferon-beta promoter activity induced by overexpression of either duck RIG-I 2CARD, full-length duck RIG-I, or duck MAVS. Finally, we show that the effect of PB1-F2 on mitochondria abrogates TRIM25-mediated ubiquitination of RIG-I CARD in both human and avian cells, while an NS1 variant from the PR8 influenza virus strain does not.

The Jurassic of Skåne, southern Sweden
Authors: Ahlberg Anders , Sivhed Ulf , Erlström Mikael
Published: April 2020

In Sweden, Jurassic strata are restricted to Skåne and adjacent offshore areas. Jurassic sedimentary rocks predominantly comprise sandy to muddy siliciclastics, with subordinate coal beds and few carbonate-rich beds. During Mesozoic times, block-faulting took place in the Sorgenfrei– Tornquist Zone, a tectonic zone which transects Skåne in a NW–SE direction. The Jurassic depositional environments in Skåne were thus strongly influenced by uplift and downfaulting, and to some extent by volcanism. Consequently, the sedimentary record reveals evidence of numerous transgressions, regressions and breaks in sedimentation. Relative sea-level changes played a significant role in controlling the facies distribution, as deposition mainly took place in coastal plain to shallow shelf environments. The alluvial deposits in Skåne include floodplain palaeosols, autochthonous coals, overbank sandstones, and stream channel pebbly sandstones. Restricted marine strata comprise intertidal heteroliths with mixed freshwater and marine trace fossil assemblages, and intertidal delta distributary channel sandstones. Shallow marine sediments encompass subtidal and shoreface sandstones with herringbone structures, and bioturbated mudstones with tempestite sandstones. Offshore deposits typically comprise extensively bioturbated muddy sandstones. Floral remains, palaeopedology, clay mineralogy and arenite maturity indicate a warm and humid climate in Skåne throughout the Jurassic, possibly with slightly increasing aridity towards the end of the period. Most Jurassic strata in Skåne have been subjected to mild burial diagenesis, and the petroleum generative window has rarely been reached.
Calcareous nannofossil and foraminifer biostratigraphy of the Campanian–Maastrichtian chalk of the Femern Bælt (Denmark–Germany)
Authors: Sheldon Emma , Morigi Caterina , Møller Sarah D.
Published: April 2020

A new study based on calcareous nannofossil and benthic and planktonic foraminifer biostratigraphy is presented for the upper Campanian – Maastrichtian chalk of the Femern Bælt (Denmark and Germany; Fig.1). The results are consistent with recent studies of the Danish chalk for this interval, allowing correlation across the Danish Basin and forming the basis for correlation further afield within the Boreal Realm. Numerous studies have been carried out recently on the upper Campanian – Maastrichtian chalk of the Danish Basin, covering aspects such as sedimentology, depositional environment, macrofossil biostratigraphy, carbon isotope stratigraphy as well as nannofossil and dinoflagellate biostratigraphy. However, very few published studies on foraminifers exist across this interval in this area. The 09.A.006, 09.A.007 and 09.A.008 boreholes (Fig. 2) were drilled in 2009 in preparation for construction of a fixed link across the Femern Bælt, which will connect Denmark to Germany (Rambøll Arup JV 2011). The boreholes penetrated glacial till, Paleocene– Eocene clay and chalk (Sheldon et al. 2012). Here, for the first time, the Boreal foraminifer biostratigraphy of the late Campanian – Maastrichtian interval is investigated and presented alongside nannofossil biostratigraphy.
Outlet glacier dynamics and bathymetry at Upernavik Isstrøm and Upernavik Isfjord, North-West Greenland

Published: April 2020

During the past decades, the Greenland ice sheet has experienced a marked increase in mass loss resulting in an increased contribution to global sea-level rise. The three largest outlet glaciers in Greenland have increased their discharge, accelerated, thinned and retreated between 1996 and 2005. After 2005 most of them have slowed down again although not to previous levels. Geodetic observations suggest that rapid increase in mass loss from the north-western part of the ice sheet occurred during 2005–2010 (Kjeldsen et al. 2013).
Katabatic winds and piteraq storms: observations from the Greenland ice sheet
Authors: Van As Dirk , Fausto Robert S. , Steffen Konrad , PROMICE project team *
Published: April 2020

In 2007 the Programme for Monitoring the Greenland Ice Sheet (PROMICE) was initiated to observe and gain insight into the mass budget of Greenland ice masses. By means of in situ observations and remote sensing, PROMICE assesses how much mass is gained as snow accumulation on the surface versus how much is lost by iceberg calving and surface ablation (Ahlstrøm et al. 2008). A key element of PROMICE is a network of automatic weather stations (AWSs) designed to quantify components of the surface mass balance, including the energy exchanges contributing to surface ablation (Van As et al. 2013).
Spatial distribution of the anisotropy coefficient in the European upper mantle
Authors: Lyskova Evgeniia , Yanovskaya Tat'iana , Koroleva Tat'iana
Published: April 2020

The radial (transversal) anisotropy of the Earth’s upper mantle was found by comparing the velocity sections of transverse waves obtained by inverse of the dispersion curves of Rayleigh and Love waves. Information on variations in anisotropy with depth was obtained from dispersion curves on fairly uniform oceanic paths. In the oceanic mantle the SH wave velocities obtained from the Love wave data are greater than the SV wave velocities determined from Rayleigh waves, so that the anisotropy coefficient is positive and is about 4% under the Moho boundary and decreases to zero at a depth of about 200 km. The information about the anisotropy of the continents is much more scarce and often contradictory due to a strong lateral inhomogeneity of the crust and upper mantle of the continents. In the European region, some authors reveal the zones where VSV>VSH in the upper mantle, whereas some others confirm VSH>VSV to be everywhere. The uncertainty in the observed values of the anisotropy coefficient is explained by the fact that it was always determined from the results of the Rayleigh and Love wave velocity tomography carried out on the basis of different samples of paths. Accordingly, the values of the SH and SV wave velocities turned out to be averaged over different regions, which led to errors in the estimates of the anisotropy coefficient. To reduce these errors, we proposed an alternative method for estimating the spatial distribution of the anisotropy coefficient: to estimate the anisotropy co-efficient in the beginning at each path and then to fulfill the tomographic inversion for this coefficient. Preliminary results on the distribution of the anisotropy coefficient in the upper mantle of Europe were presented according to an earthquake and seismic noise. However, analysis of the anisotropy coefficient values obtained from the earthquake data and seismic noise has shown that those obtained from noise are usually underestimated. Therefore, in the present study, we used only the data obtained from earthquakes. It was shown that the anisotropy coefficient under the continental part of the European region is close to zero but two areas where VSV>VSH are detected – in the central part of EEP and in southern Italy. In both cases, the negative values of the anisotropy coefficient are observed within the interval of ~60–100 km depth.

Published: April 2020

Soap is a mixture of sodium compounds with fatty acids that are used as a body cleansing agent, in the form of solid, foam, with or without other additives and does not cause irritation to the skin. To improve quality, bath soap can be given additional ingredients that contain vitamins and various nutrients needed by the skin such as the addition of extracts of karika fruit (Carica pubescens). The purpose of this research is to find out the right formulation in making karika soap. This research used an experimental method with randomized block design (RCBD), consisting of two factorial variations in the concentration of karika juice (0%, 100%, 80%, 60%) and variations in the concentration of NaOH (30%, 35%, and 40% ) so that 12 treatments were obtained each with 3 replications. The process of making soap uses the hot process method. Soap quality analysis is carried out by comparing the results of chemical tests for karika soap with SNI 06-3532-1994 (SNI for solid bath soap), foam stability test, soap hardness, and organoleptic test. The data obtained were analyzed using ANOVA with a confidence interval of 5%. If an effect is found on one of the variebel, a further Tukey test is performed. The results showed that the water content, pH, and free alkali did not meet SNI, while the amount of fatty acids and mineral oil was in accordance with SNI, the significant difference between treatments was only in the water content. Karika soap has abundant and stable foam. The higher concentration of karika juice make the lower hardness of the soap. Organoleptic test results showed a low level of preference for panelists on karika soap products. The suggestion from this research is that karika juice can be tried to applied it in the liquid bath.

Published: April 2020

Purpose. To study the clinical features of non-psychotic depression and autoaggressive manifestations (AM) in cancer patients and to identify ways of improving the quality of medical support indicated patients.
Materials and methods. Clinical and paraclinical methods xamined 30 women with tumors of the female reproductive system ІІ-ІІІ stages: cervical cancer (C52) cancer of the vagina (C53) at age of 42 to 65 years (mean 47±0,5), who asked to diagnostic and treatment in the Department of radiotherapy of the National cancer Institute in a month or more after the establishing of cancer diagnosis, and outpatients treated with depressive complaints and the AM, to the Department of psychiatry and narcology of Bogomolets National Medical University. These patients are examined by oncologists, gynecologists, internists, neurologists, psychiatrists, endocrinologists, using clinical-psychopathological, clinical-dynamic, catamnestic, paraclinical methods, followed by radiation therapy, chemoradio therapy, psychopharmacotherapiy and psychotherapy. Catamnestic observation lasted from one to two years.
Results and discussion. AM was diagnosed in 30 of the women surveyed in the cancer (C52; C53) with depression underneurotic and stress-related disorders (ICD -10; F4). Highlighted anxious (n = 12; 40%), astheno-subdepressivee (n = 7; 23,3%), phobic (n = 6; 20%), dysphoric (n = 5; 16.7%) syndromes. About half of the 12 (40%) patients had accentuation of character, disharmony of personality and psychopathic traits.
Thus, patients with the cancer dominated by anxious-depressive, subdepressive and phobic disorders, rarely dysphoric disorder, which was confirmed by the aggregation (p <0.05; p <0,05-0,01).
Conclusion. In cancer patients with cancer (C52, C53) with depression and isdominated by AM, anxiety-depressive, astheno-subdepressive and phobic disorders, rarely dysphoric disorder (ICD-10; F4) that worsen the medical condition, prognosis and treatment of the underlying disease, reduce the quality of life of patients, increase the risk of suicide. The solution of this problem requires integration of efforts oncological, psychological, psychiatric and other institutions in the unifiedstate strategy.

Published: April 2020

Acetylcysteine (ACC) is a mucolytic, expectorant medicine with antioxidant, anti-inflammatory, anti-infective, radioprotective, pulmonary protective, anticarcinogenic and antitoxic effects. The review describes the examples of ACC application in radiation diagnostics and therapy for pharmacological radioprotection of the patient’s body and organs. ACC mitigates the negative effects of radiation therapy on the healing of a postoperative wound by reducing oxidative stress markers. ACC significantly reduces the x-ray density of breast tissue, that is, reduces the cancer risk. It has been proven that intravenous and oral administration of ACC prevents nephropathy caused by radiopaque agents. The clinical effectiveness of ACC in the treatment of acute and chronic neurological syndromes of radiation disease is assumed.

Este novo conceito de propriedade baseada em princípios econômicos – de economia política e não de economia moral - estava sendo teorizada desde final do século XVIII, mas foi no século XIX, e sobretudo a partir do código napoleônico que ganhou autoridade plena.

Novas funções e novas atividades como alternativas de desenvolvimento da agricultura familiar no Brasil
Authors: Machado André Grossi , Caume David José
Published: April 2020

O objetivo deste artigo é discutir alternativas de desenvolvimento da agricultura familiar no Brasil com um enfoque voltado aos conceitos de pluriatividade da agricultura familiar e multifuncionalidade do espaço agrário. Dentro dessa abordagem, e procurando comparar com a situação de outros países, objetiva-se explicar as especificidades, assim como as oportunidades e limitações da aplicação desses conceitos no país. A conjugação desses conceitos pode levar a um modelo sustentável de desenvolvimento rural, proporcionando a fixação e manutenção de famílias no campo ligadas a atividades como a agricultura orgânica, agroecologia, turismo rural, ecoturismo, artesanato e pequenos beneficiamentos de alimentos. Conclui-se que os formuladores de políticas voltadas ao desenvolvimento rural podem se beneficiar dessas idéias, e mais iniciativas deveriam ser tomadas relacionando os dois conceitos.

Analisa data menggunakan Analisis data kualitatif dengan model  interaktif.          

Berdasarkan hasil penelitian ini diperoleh hasil bahwa pengajuan klaim dan pemberian santunan kecelakaan lalu lintas jalan berdasarkan pada UU No. 34 Tahun 1964 jo PP No. 18 Tahun1965. Pemberian santunan yang diberikan terhadap korban kecelakaan lalu lintas jalan berdasarkan pasal 11 PP No. 18 Tahun 1964, Surat Keputusan Menteri Keuangan RI No. 416/KMK.06/2001 serta didasarkan pada Keputusan Direksi. Santunan kecelakaan lalu lintas jalan akan diberikan kepada setiap orang yang berada diluar alat angkutan lalu lintas jalan yang menimbulkan kecelakaan, yang menjadi korban akibat kecelakaanyang disebabkan alat angkutan lalu lintas jalan tersebut, dengan pengecualianyang tercantum dalam pasal 13 PP No. 18 Tahun1965. Pelaksanaan Asuransi Sosial Kcelakaan Lalu Lintas Jalan merupakan suatu upaya pemerintah dalam memberikan perlindungan jaminan sosial kepada masyarakat khususnya korban kecelakaan lalu lintas jalan. Pihak Jasa Raharja tetap memberikan dana santunan kepada korban kecelakaan lalu lintas jalan yang disebabkan oleh alat angkutan lalu lintas jalan yang lalai membayar sumbangan wajib, yang kemudian pihak Jasa Raharja dapat menuntu balik kepada pemilik kendaraan penyebab kecelakaan yang lalai dalam pembayaran sumbangan wajib untuk membayar semua penggantian kerugian yang telah dikeluarkan oleh Jasa Raharja. Mengenai hal ini diatur dalam Pasal 14 huruf d PP No. 18 Tahun 1965.

Implikasi teoritis ini adalah adanya pembaharuan dalam pengaturan asuransi sosial kecelakaan lalu lintas jalan, yaitu merubah dan melengkapi UU No. 34 Tahun 1964 jo PP No. 18 Tahun 1965, sedangkan implikasi praktisnya adalah hasil penelitian ini dapat dipakai sebagai rujukan pelaksanaan asuransi sosial kecelakaan lalu lintas jalan oleh PT (persero) Jasa Raharja Sulawesi Tenggara Perwakilan Kolaka dalam pelaksanaan Asuransi sosial Kecelakaan Lalu Lintas Jalan.
СИСТЕМА МОНІТОРИНГУ ЗАБРУДНЮЮЧИХ ГАЗІВ ТА СПОСІБ РЕГУЛЮВАННЯ ТЕМПЕРАТУРНО-ВОЛОГІСТНОГО РЕЖИМУ ТВАРИННИЦЬКИХ ПРИМІЩЕНЬ

Published: April 2020

Метою роботи було розробити інноваційну систему моніторингу забруднюючих газів та спосіб регулювання температурно-вологістного режиму тваринницьких приміщень. Методи. Дослідження проводили в умовах технологічної лабораторії Черкаської ДСБ НААН і лабораторії ФОП «Онищенко Р.О.». Розроблення газоаналітичної та структурної блок-схем здійснювали шляхом узагальнення літературних даних за тематикою досліджень та виготовлення технічних креслень і робочої документації вимірювальних блоків та блоку керування. Проведено закупівлю складових елементів, монтаж і пуско-налагоджувальні роботи вимірювальної системи. Розроблено програмне забезпечення мікропроцесорної системи та спосіб регулювання температурно-вологістного режиму. Результати. Розроблено мультипараметричну систему моніторингу забруднюючих газів тваринницьких приміщень. Вона є автоматизованою, компактною і портативною. Основною частиною системи виступає мікроконтролер. Мультипараметрична система дозволяє оперативно здійснювати оцінку санітарно-гігієнічних умов утримання тварин для прийняття відповідних управлінських рішень. Теплокровні тварини характеризуються розвинутим гомеостазом температури тіла та інших фізіологічних параметрів організму. Занадто стабілізовані впродовж доби умови мікроклімату є причиною надмірного зніження тварин. У зв’язку з цим, в приміщенні для утримання ремонтного молодняку кролів циркадне коливання температури взимку має становити від 8 до 11°C, у перехідний період року від 13 до 16°C і влітку від 18 до 21°C. Аналогічно повинна змінюватися і відносна вологість повітря взимку від 62 до 74 %, у перехідний період від 60 до 72% і влітку від 58 до 70 %. Впродовж добового періоду, запрограмований мікропроцесор, через заданий проміжок часу (2 год.) з відповідним кроком (0,5 °C) задає сигнал необхідної температури та з відповідним кроком (2 %) задає сигнал необхідної відносної вологості повітря. Висновки. Перехід вітчизняного кролівництва на промислову основу сприяв запровадженню кліткового способу утримання тварин у приміщеннях з контрольованим мікрокліматом. Мультипараметрична вимірювальна система здійснює добовий моніторинг низки забруднюючих газів в автоматизованому режимі, що економить 200-224 люд./год. робочого часу в рік зоотехніка-технолога. Експлуатаційні затрати на одне дослідження компонента шкідливого газу в 2,5 рази менші, ніж хімічними методами. Впровадження циркадного ритму дозволяє забезпечити фізіологічні потреби тварин у ритмічних добових змінах температури і відносної вологості повітря тваринницького приміщення. Це дозволяє підвищити резистентність організму тварин, шляхом стимулювання роботи нервової та нейрогуморальної систем.
