Novel cellular materials for energy absorption applications
Authors: Mudassir Mohammed , Mansour Mahmoud
Published: June 2020

Cellular materials such as metal foams are porous, lightweight structures that exhibit good energy absorption properties. They have been used for many years in various applications including energy absorption. Traditional cellular structures do not have consistent pore sizes and their behaviors and properties such as failure mechanisms and energy absorption are not always same even within the same batch. This is a major obstacle for their applications in critical areas where consistency is required. With the popularity of additive manufacturing, new interest has garnered around fabricating metal foams using this technology. It is necessary to study the possibility of designing cellular structures with additive manufacturing and their energy absorbing behavior before any sort of commercialization for critical applications is contemplated. The primary hypothesis of this senior project is to prove that energy absorbing cellular materials can be designed. Designing in this context is much like how a car can be designed to carry a certain number of passengers. To prove this hypothesis, the paper shows that the geometry is a key factor that affects energy absorption and that is possible to design the geometry in order to obtain certain behaviors and properties as desired. Much like designing a car, it requires technical expertise, ingenuity, experience and learning curve for designing cellular structures. It is simple to come with a design, but not so much when the design in constrained by stringent requirements for energy absorption and failure behaviors. The scope was limited to the study of metal foams such as the ones made from aluminum and titanium. The primary interest has been academic rather than finding ways to commercialize it. The study has been carried out using simulation and experimental verification has been suggested for future work. Nevertheless, the numerical or simulation results show that energy absorbing cellular structures can be designed that exhibit good energy absorption comparable to traditional metal foams but perhaps with better consistency and failure behaviors. The specific energy absorption was found to be 18 kJ/kg for aluminum metal foams and 23 kJ/kg for titanium metal foams. The average crushing force has been observed to be around 70 kN for aluminum and around 190 kN for titanium. These values are within the acceptable range for most traditional metal foams under similar conditions as simulated in this paper.
Features of anxiety and depressive disorders in woman during pregnancy
Authors: Molotokas Antonina
Published: June 2020

The phenomenon of pregnancy is one of the most important factors in the formation of a specific complex of anatomical-physiological, neuro-psychological, psychological and socio-psychological formations and changes of women, which are most often described in the literature by the term «maternal sphere of personality», «maternity» At the same time, the pregnancy in women and the phenomena caused by it are, firstly, the specific phase of gender and individual ontogeny, and secondly, multilevel, multidimensional education, causing the above specific changes in its gender status. Pregnancy and depression often go hand in hand. This condition affects about every tenth pregnant woman. According to recent research, sudden surges and changes in the hormonal background that accompany the entire pregnancy can really affect brain biochemistry, which in turn can lead to real clinical depression. If a woman had problems with conception or she was treated for infertility, the probability of her depression in her pregnancy increases by 10 times. Depression may be more likely to eclipse pregnancy and women who have suffered mental illness, anxiety, or depression before conception. This disorder may also occur in problematic relationships, as well as in situations where relatives have had a depression or mental illness, a woman has already had a miscarriage or her current pregnancy is a high-risk group. Depression during pregnancy has significant implications for pregnancy outcomes and maternal and child health. There is a need to identify which family, physical and mental health factors are associated with depression during pregnancy.

Authors: Rudenko Oksana
Published: June 2020

The article presents the results of theoretical research of the problem of psychological well-being, personal qualities of the teacher highlights as the main markers that determine the choice of the positive functioning of the teacher and provide his psychological well-being. The specificity of motivating and stabilizing personal qualities highlighted in the context of personality-professional development of the teacher.The article analyzes «job satisfaction» as a component of the teacher’s subjective well-being, that reflects personal well-being in professional employment and provide its professional identity. In relation to pedagogical activity, satisfaction is determined by the relationship between the motivational value sphere of the teacher’s personality and the possibility of success of the activity in implementing the leading motives and acts like the main psychological mechanism of the behavioral substructure of self-consciousness. Emotional intelligence and developed social skills are also determinants of psychological teacher’s well-being.
The problem of health are substantiated (physical, mental and social) as a professional category of well-being, the measure of a person’s ability to act as an active subject of his professional activity is substantiated; the concept of psychological status are expanded in the context of mental health of personality. The specifics of the educational environment as a system of relations of all subjects of professional activity is determined by an important determinant of psychological teacher’s well-being, which determines the success of the disclosure of their potential, satisfaction of the need for self-realization.
Socio-psychological mechanisms of adaptation and integration of internal transmitted persons in the community
Authors: Fedorenko Oleksandra
Published: June 2020

This article is devoted to the case study of the social and psychological adaptation and integration of internally displaced persons in the host community. Theoretical analysis of modern local and foreign studies has been performed. A theoretical analysis of contemporary domestic and foreign researches was effectuated, during which the specialities of the socio-psychological mechanisms of adaptation and integration of internally displaced were identified. It was clarified that the process of adaptation involves acceptance and adaptation to social norms, and as a result of integration, the emergence of new formations that meet the needs of individual and group development takes place. Also, there were an attempt to define the existence of distinctions of the migrants, refugees, internally displaced persons and their special aspects of adaptation. The complexity of the social and psychological adaptation of internally displaced persons lies in the fact that the result of the process should be the conformity to socially regulated behavior, interests, and values orientations of community without losing its own individuality. Research findings point to the significant potential of internally displaced persons, which can contribute to improving the adaptive capacity of the entire community, to manifest itself in the cultural, social and working life of the host party.The material presented in the article emphasizes the importance of a more careful study of the mechanisms of adaptation and integration.
Correction of citizenship of population by types of healthy oriented therapy
Authors: Voitenko Oksana
Published: June 2020

The most important feature of adolescence is awareness of responsibility for the content of their lives before themselves and before other people. The psychological signs of a mature adult present a certain level of self-regulation, the specifics of experiencing ontological problems, the relation to the environment, the existence of a balance between the level of appetites and the satisfaction of their achievements. Overcoming the age limits of youth, the individual experiences differently. Some consider this stage of life as a new opportunity to realize their potential, others feel dissatisfied, internal embarrassment and anxiety. A man’s view of his mature adult may be due to the economic conditions of life, social circumstances and peculiarities of the time in which he lives. Many adults begin to feel that it is difficult for them to dispose of their own lives. In a situation of psychological deprivation, an adult is worried and confused about whether she really understood and realized the true purpose of her life. That is why it is important to notice in time and respond to emotional violations of the ontological direction. In our study, we aimed to analyze the empirical indicators of adult anxiety and test the means of correctional influence in the perspective of bodily oriented psychotherapy (TOP), which indicates the path to effective problem-solving without time and cognitive resources. The main task of our corrective work with the researchers was to intensify the manifestation of positive emotions through the removal of bodily and psychological clamps; personal anxiety was regulated by promoting physical and psychological liberation; extending the range of emotions in interaction with the outside world. In addition, we have induced participants of the TOP to form new, more effective patterns of motion; learning self-regulation skills and ability to realize stress through situations of stress. The correctional program had a positive effect on the emotional state of the participants in the experiment. In particular, it proved to be effective for dealing with reactive (situational) anxiety.
Features of the manifestation of posttrummatic stress disorders of ato participants
Authors: Herasina Svitlana
Published: June 2020

The article represents theoretical substantiation of the problem of the impact connected with traumatic events related to the military conflict in the east of Ukraine, on the psycho-emotional state of the soldiers participating in the antiterrorist operation (ATO). There is analysis of modern scientific researches on the interdependence of combat stress with post-traumatic emotional frustration of fighters, causing: intrusive memories, flashbacks and sleep disturbances; avoidance, manifested in emotional distress, apathy, indifference, despair, depression; hyperactivation, which manifests itself in agitation, intense emotional and physiological excitement, and in unproductive psychomotorism. There is proving of the expediency of psychodiagnostic method «Mississippi Scale» (military option) in the study of symptom complexes: «intrusions» – emotional jostling; «Avoidance» – suppression of traumatic memories; «hypersensitivity» – hypertrophied psychophysiological reactions; feelings of guilt and shame and suicidal inclinations. There is empirical definition of psychological peculiarities of respondents with post-traumatic stress disorder as a kind of neurosis, manifested as a result of the simultaneous experience of several psychotraumatic events by a fighter. There is disclosure of PTSD as a delayed reaction of the individual to a stressful event of a threatening nature, which also caused chronic stress – distress. The psychopathological condition of fighters is revealed, which is caused by the necessity to perform responsible combat tasks under the conditions of extreme ATO factors. There is determination of destructive mental states that are developing in the military and in the period of adaptation to the usual conditions of life and service, after returning from the war that reduces the stress resistance and the process of social adaptation.There is description of stressful factors: high responsibility, danger, death of friends, injury, contusion, disability, long stay in the ATO, etc., which destructively affect the psychological health of the soldiers. The basic psychotherapeutic strategies of psychoanalysis of ATO participants are offered: updating of adaptive skills and renewal of own resources of «I»; formation of «positive attitude» to the symptom; reduction of avoidance, focus on the transformation of psychotraumatic experience; change in the attribution of the content of the traumatic situation and its consequences, the feeling of its own «control and authority over the psychotrauma».
Formation of the life competence as the basis for personalized development of a primary school child
Authors: Hurina Zoia
Published: June 2020

The article presents the research theoretical analysis of personality’s competence, it reveals its components and characteristics; the competence is considered from the point of view of cultural-historical theory of higher psychic functions made by L. Vyhotskyi, according to which the intellectual development of personality is implemented through acquisition by meanings of words and visual symbols, as well as it demonstrates the procedural-active approach (S. Rubinshtein, A. Brushlynskyi, L. Venher), in which the key concept is «thinking and ability», and it is determined that the essence of intellectual education should consist in formation of personality’s ability to understand and generate the new thoughts. Competence is defined by scientists as the ability to make decisions and bear responsibility for their implementation in various fields of human activity. The concept of competence implies combination of physical and intellectual qualities of a person and the properties necessary for independent and effective way out from different life situations. Competence implies the appropriate level of personal mechanisms development, such as repetition, identification, imitation, empathy, reflection, image of «I», conscience, corresponding to age opportunities and individual life stories of a child. 

In psychological and pedagogical literature, different aspects of competence are considered: competence in communication, cognitive competence, social and psychological competence, life competence, etc. Communicative competence is considered as a system of internal resources necessary for building the effective communication in a certain range of situations during the interpersonal interaction. Cognitive competence makes it possible to determine what is true and what is false. Competence in the emotional-volitional sphere implies the preschooler’s morality formation. As the indicators of vital competence the scientists determine the activity of a child in gaming, subject-practical activities, communication and basic qualities formation in personality.
Localization of subjective control and features of self-attitude of deprived youth
Authors: Kiz Olha
Published: June 2020

The article deals with the influence of deprived conditions of socialization in institutional care institutions on the formation of the locus control and self-attitude of personality. The results of empirical research about the features and correlations between some scales of the studied phenomenon have been presented. It has also been found that the deprived youth both sexes have difficulty in self-absorbed, contradictory self-attitude, negative emotions to himself / herself, and the external type of locus control regardless some positive self-attitudes.In the deprived conditions of parental-child interaction, the emotional and value self-attitude of youth has been characterized as reduced ability to self-reflection, feeling guilty, internal conflict, a tendency to self-incrimination, which forming a dependent position in the development of intimate and reference contacts, narrowing the abilities for self-realization in preparing for independent life. Youth of both sexes with deprived experience are insecure in themselves, their potencies and opportunities. They have some ability to building a line of behavior independently; obeying the attitudes about their inferiority and insignificance in the regulation of life; the lack of interest of their internal world; the low assessment of the value of their own image “I” for himself / herself and for others; the expectation of unfavorable reactions, lack of sympathy, negative self-attitude, self-incrimination, self-analysis and self-criticism.In the conditions without psychological and correction work, the diffuse self- attitude causes a self-rejection as a big hurdle to the adaptation and integration into society and destabilizing effect on the possibility of successful personal self-realization in the future. The above actualizes the problem of socio-psychological support of growing personality in current conditions of a variety of deprivation, which provides necessary opportunities for deprived youth of both sexes to compare their real possibilities with the society requirements, their own behavior with the expectations of other people; and opportunity for self-asserted and self-development, resolving internal conflicts.
Risks of Propofol-based Total Intravenous Anesthesia Compared with Local Anesthesia in Patients Undergoing Percutaneous Transluminal Angioplasty in The Lower Extremity
Authors: Wongwiwattananon Wejpisit , Pakpirom Jatuporn , Akarapatima Raviwan
Published: June 2020

Objective: This study aimed to determine the risks of propofol-based total intravenous anesthesia (TIVA) compared to local anesthesia (LA) in patients undergoing percutaneous transluminal angioplasty (PTA) in a lower extremity. Material and Methods: A retrospective cohort study was conducted in 231 patients who underwent PTA in the lower extremity using either propofol-based TIVA or LA between January 2016 and September 2018. The outcomes of interest included perioperative major adverse cardiac events (MACE) and minor perioperative complications. Risk factors analysis was performed using a univariate logistic regression and backward stepwise multivariate logistic regression. Results: Although the rate of perioperative MACE was two times higher in the propofol-based TIVA group (7.8%) than the LA group (3.9%), no significant difference was found (p-value=0.221). The propofol-based TIVA group had a significantly higher incidence of all minor perioperative complications than the LA group (77.6% vs 13.6%, p value<0.001). Multivariate analysis found that low body mass index (BMI) and American Society of Anesthesiologists classification III were independent factors associated with perioperative MACE, while propofol-based TIVA, body weight (or BMI), hypertension, diabetes mellitus, previous coronary artery disease, and previous congestive hear failure were associated with perioperative minor complications. Conclusion: Based on this study, no significant differences in perioperative MACE were found using either TIVA or LA. However, TIVA produced a significantly higher incidence of perioperative minor complication than LA. Close intraoperative monitoring should be implemented when using propofol-based TIVA in patients undergoing PTA in the lower extremity.

Authors: Udaya K , Murteli Vijaykumar B , Desai Arun
Published: June 2020

Background: Acute respiratory infections (ARIs) are a public health problem in India. Timely intervention, correct treatment, and referral service can save many deaths, particularly pneumonia. Objective: This study aimed to study the sociodemographic and clinical profile of children hospitalized with pneumonia and its relation to the duration of stay at a tertiary care center at Belgaum district, Karnataka. Methodology: The study was conducted in Belagavi Institute of Medical Sciences, a referral hospital, during 2013-2015.  Sociodemographic and clinical features of children aged from more than 2 months to 18 years of age were studied. A total of 84 children who met the inclusion criteria for community-acquired pneumonia were studied. The patient population comprises mainly of the low-income group from rural areas, urban slums, referred patients from surrounding rural areas, and private clinics. Results: A total of 84 children were studied, 48 boys and 36 girls. Maximum numbers of children were in low socioeconomic group (43 in upper lower and 37 in lower group) according to modified Kuppuswamy classification. Passive smoking was present in 40.5% of studied and overcrowding was seen in 51% of children studied. 44% of children were breastfed for <6 months, and 30.64% were partially immunized. There is a significant association between passive smoking, delayed medical attention, and duration of stay. Conclusion: With this study, we can conclude that children who got early medical attention (<4 days) stayed for less period of time in the hospital (<7 days). Children exposed to passive smoking had a longer duration of stay.
Clinico-epidemiological profile of snake bite in children - A descriptive study
Authors: Sahni Gopal Shankar
Published: June 2020

Background: Snakebite is one of the important causes of occupational hazard in our country. The state of Bihar has the third largest number of snakebite deaths in India. Objective: Our aim was to study the clinical profile, seasonal pattern, complications and outcome in patients of snake bite in pediatric age group. Materials and Methods: This was a record-based retrospective study conducted at Sri Krishna Medical College, Muzaffarpur. Data were collected for patients admitted between 1 July 2015 and 30 June 2016. Patients were included if they had a history of snakebite or unknown bites. Results: There were 51 males (60%) and 34 females (40%) out of 85 patients studied. Among them, 50 patients had krait bite, 25 patients had Cobra bite, 2 patients had viper bite, and in 8 patients snake was not identified. Majority of the snake bites were in the lower limbs (80.0%). The highest number of cases occurred during June-October month (42%). Mortality in our study was 6%. The most common symptom detected was pain abdomen (80%), ptosis/ophthalmoplegia (82.35%), altered sensorium (29.41%), and respiratory difficulty (35.29%). Conclusions: Common krait (Bungarus caeruleus) accounted for the highest number of venomous bites. Lower limb was the most common bitten site. Victims were from a rural background, and most of them were bitten indoors and during the night time. Identification, timely diagnosis and early administration of anti-snake venom will certainly aid to curb mortality in snake bite.
Melatonin as a potential therapeutic molecule against COVID-19 associated gastrointestinal complications: An unrevealed link
Authors: Pal Palash Kumar , Chattopadhyay Aindrila , Bandyopadhyay Debasish
Published: June 2020

Outbreak of the novel coronavirus disease (COVID-19) was first reported in Wuhan, Hubei province of China, in early December 2019 which was later declared as a pandemic by World Health Organization (WHO) in March 2020. The International Committee on Taxonomy of Viruses has termed this novel coronavirus as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to the report of WHO on 29th April, 2020, 3018681 confirmed cases along with 207973 deaths have been documented globally. COVID-19 was originally reported as a lethal lung disease with fever and cough as the most common symptoms; however, the increasing number of gastrointestinal symptoms, such as diarrhoea, vomiting and abdominal pain in patients have clearly suggested that gastrointestinal tract (GIT) may also serve as a potential route for SARS-CoV-2 infection. To identify the effective therapies on this pandemic is urgent. Keeping this in mind, we realize that melatonin is a potent antioxidant, anti-inflammatory and immunomodulatory molecule and it has been used in diverse diseases and pathophysiological conditions, including respiratory disease and viral infections. Importantly, melatonin specific receptors and its endogenously synthetic machinery are distributed throughout the mammalian gastrointestinal system. Therefore, the therapeutic potentiality of melatonin in SARS-CoV-2 associated digestive symptoms cannot be ignored. In this review, we focus on the clinical implications of melatonin on the digestive complications associated with SARS-CoV-2 infection.
Genetic polymorphism in populations of voles and shrews from the Kronotsky Reserve (Kamchatka Peninsula, Russia)
Authors: Zhigileva O. N. , Levykh A. Y. , Gorbacheva E. V.
Published: June 2020

We studied genetic polymorphism of four mammal species Myodes rutilus, Myodes rufocanus, Sorex isodon, from four localities, the Valley of Geysers, Uzon volcanic caldera, the Death Valley, and the Shore of Kuril Lake. In total, 172 individuals were genotyped using the inter-simple sequence repeat technique. We observed the lowest polymorphism in shrews S. caecutiens. In this species, 68.8 % of bands were polymorphic, and Nei’s genetic diversity (h) was 0.27, while these values in S. isodon were 81.3 % and 0.29, respectively. Populations of M. rufocanus were the most polymorphic among the studied species (P = 91.4, h = 0.34). Polymorphism in M. rutilus from Kamchatka (P = 87.2, h = 0.29) was similar to that from Western Siberia. In addition, we found a high genetic differentiation of rodent populations. The interpopulation component of genetic variability was about 30–40 % (GST = 0.31 in M. rutilus and 0.39 in M. rufocanus). Gene flow among populations of M. rutilus from Kamchatka was two times lower than that of populations of the species from taiga ecosystems in Siberia.

Conflict of Interest policy
Authors: Balogh Lajos P
Published: June 2020

Public trust in the peer-review process and the credibility of published articles depend in part on how well conflict of interest is handled during writing, peer review, and editorial decision making. Conflict of interest exists when an author (or the author’s institution), reviewer, or editor has financial or personal relationships that inappropriately influence (bias) his or her actions (such relationships are also known as dual commitments, competing interests, or competing loyalties).

These relationships may vary from those with negligible potential to those with great potential to influence judgment, and not all relationships represent true conflict of interest. The potential for conflict of interest can exist whether or not an individual believes that the relationship affects his or her scientific judgment. Financial relationships (such as employment, consultancies, stock ownership, honoraria, paid expert testimony) are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the reviewers, and the authors.

However, conflicts can occur for other reasons, such as personal relationships, academic competition, and intellectual passion. Please, note that the appearance of a conflict also constitutes a conflict of interest.

The Use of Soundscapes to Monitor Fish Communities: Meaningful Graphical Representations Differ with Acoustic Environment
Authors: Carriço Rita , Silva Mónica , Vieira Manuel , Afonso Pedro , Menezes Gui , Fonseca Paulo , Amorim Maria
Published: June 2020

Many marine animals produce sounds in several phases of their life cycles, either actively or as a byproduct of their activities, such as during mate attraction or when moving. Recent studies of underwater soundscapes have proved passive acoustic monitoring to be a cost-effective, non-invasive tool to understand ecological processes, especially when sampling in adverse conditions or at great depth. Four days of sound recordings at three seamounts from the Azorean archipelago were examined to assess the suitability of different sound graphical representations to characterize different acoustic environments that contrast in the contribution of vocal fish communities. Long-term spectrograms, sound pressure level, spectral probability densities and the Acoustic Complexity Index (ACI) were computed for two shallow seamounts (Formigas and Princesa Alice, c. 35 m) and one deep seamount (Condor, 190 m) using graphics with different time spans. Only in Formigas, which presented the highest occurrence of fish sounds, was it possible to observe temporal patterns of fish vocal activity in the graphical representations. We highlight that habitats with a higher diversity and abundance of sounds are the most suitable targets for these methods, while in locations with a low prevalence of fish sounds a combination of several methods would be recommended.
Feedforward Plus Feedback Control of an Electro-Hydraulic Valve System Using a Proportional Control Valve
Authors: Ko Young-Rae , Kim Tae-Hyoung
Published: June 2020

The output feedback signal of the electro-hydraulic valve system (EHVS) affects the activation of its right or left envelope function; thus, even weak measurement noise can cause high-frequency switching between the two envelope functions, leading to chattering in the control input. Consequently, feedforward and feedback controllers in a cascaded configuration generate undesirable chattering in the output signal. We propose a practical and reliable control approach for an EHVS actuated by a proportional control valve. The proposed controller has a parallel structure comprising an inverse generalized Prandtl–Ishlinskii (P–I) model-based feedforward controller, with both hydraulic dead-zone and flow saturation limits, for compensating asymmetric hysteretic behavior. Further, the proposed controller comprises a robust proportional-integral-derivative (PID) feedback controller for achieving robustness against disturbances and noises. The proposed parallel structure is independent of the output feedback of the EHVS. Moreover, the proposed robust PID feedback controller guarantees EHVS stability by precisely selecting the cutoff frequency for the sensitivity and complementary sensitivity functions based on the amplitude spectrum of the inverse-model-based feedforward compensation error. The results verify the high reliability of the proposed EHVS control scheme for the precise control of an EHVS actuated by a proportional control valve in practice.

We investigate the level of tolerance towards tax non-compliance and the informal economy in Romania, using a sample of 250 respondents. This variable is determined by a complex set of latent variables that include, but is not limited to, state capacity, social and business norms, the perception of non-compliance, and the perception of distributive justice. We find that our respondents are intolerant towards tax evasion and the informal economy, but the level of intolerance is relatively mild. Using a partial least squares—path modeling approach, we also find that a weak state capacity and the perception of lack of distributive justice increases the level of tolerance. The perception of tax evasion stemming from media reports, and the respondents’ own self-enhancement bias, combine to push the level of tolerance lower.
Evaluation of Asphalt Concrete Airport Pavement Conditions Based on the Airfield Pavement Condition Index (APCI) in Scope of Flight Safety

Published: June 2020

Airoport infrastructure development requires care to maintain it in proper technical condition. Due to this, airport pavements should be constantly monitored, and, above all, correctly managed. High-level airport pavement management requires access to reliable information about their current technical condition as well as proper forecasting of this condition in the future. Obtaining good quality information about the technical condition of airport pavement should be based on a proven methodology, taking into account the introduced quality management system. The authors propose a method of technical pavement condition assessment based on the Airfield Pavement Condition Index (APCI), taking into account not only the results of the surface deterioration inventory, but also repair overviews, load bearing capacity, evenness and roughness of the surface, as well as the surface tensile bond strength. The method was developed during long-term work financed by the Ministry of Science and Higher Education. At the beginning of the article, the authors focus on reviewing the currently available methods of assessing the technical condition of the pavement. Then they briefly present the most popular surface assessment method based on the PCI indicator. Afterwards, a proprietary asphalt pavement assessment method based on the APCI indicator is proposed and an example of how to use the method is presented. Finally, they discuss the results and summarize the work done, and present further directions of work.
Effects of Thickness of Solid Media, Ventilation Rate, and Chamber Volume on Ammonia Emission from Liquid Fertilizers Using Dynamic Chamber-Capture System (DCS)
Authors: Kim Min-Suk , Kim Jeong-Gyu
Published: June 2020

This study was conducted with the aim of improving the dynamic camber-capture system, which estimates ammonia emissions during the application of liquid fertilizer from livestock manure. We focused on the volume of the chamber and headspace, the height of the solid media, the flow rate of the pump, and the ventilation rate. Total ammoniacal nitrogen (NH3 + NH4+) is an important factor affecting ammonia volatilization. Even though the characteristics of liquid fertilizer were changed, the effect of total ammoniacal nitrogen on ammonia volatilization remained the largest. Increasing the thickness of solid media inside the chamber has the effect of reducing ammonia emission by reducing the contact area between liquid fertilizer and air. Although it is very difficult to measure and control the wind velocity in a chamber using a general vacuum pump, it can be indirectly evaluated through the ventilation rate in the macroscopic aspect. The higher the ventilation rate, the faster the flow of air in the chamber, which is linear with the increase in ammonia emission flux. We find that it may be necessary to improve the steady wind velocity within the chamber and of the linkages to upscale the wind tunnel system.
Economic Contributions of Mega-Dam Infrastructure as Perceived by Local and Displaced Communities: A Case Study of Merowe Dam, Sudan

Investigations on the socioeconomic impacts of mega-dam projects have tended to focus on conventional cost–benefit analysis, while studies exploring perceptions of local communities, who are some of the prime beneficiaries of these development initiatives, are limited. This paper aims to address this research gap through a case study of community perceptions on the socioeconomic impacts of the Merowe Dam in Sudan from the residents of upstream, downstream, and relocated locations. Data were collected primarily through surveys and interviews with residents, government officials, dam implementation authority, non-governmental organizations (NGOs) and other key informants and a series of indicators were developed for the analysis from the responses. Three inter-related areas of impact were scrutinized: (a) electricity generation; (b) development of modern agriculture; and (c) institutional infrastructure in the region. The results reveal that local communities are fully aware of both the positive and adverse socioeconomic impacts of the Merowe Dam, although these are focused more on the visible impacts closely related to their livelihood and income, such as increased food production, water shortages, electricity supply and its costs. Policy implications include investments in the new settlement areas with respect to the agricultural economy, such as irrigation improvement through electrification, promoting crop diversity, research, development, and diffusion of modern agricultural technologies. Efforts are also needed to strike a balance between provision of utilities and services, (i.e., water, electricity and other infrastructural facilities) provided by the Merowe Dam, amongst communities in relocated, upstream, and downstream locations.

This study aimed to investigate how farrowing and rearing systems affect skin lesions, serum cortisol, and aggressive behavior as indicators for weaning stress of piglets. Between May 2016 and March 2018, in total 3144 weaning piglets from three different farrowing systems were examined: farrowing crates (FC), single-housing free-farrowing pens (FF), and group-housing of lactating sows and litters (GH). After weaning and regrouping, piglets were relocated to conventional rearing pens (conv; 5.7 m2) or to wean-to-finish pens (w-f; 12.4 m2). Skin lesions were scored 24 h after weaning. Blood samples were taken one week before and 24 h after weaning to analyze the individual difference in serum cortisol. Behavior was observed for 24 h after relocation. Animals raised in FC and FF had significantly more skin lesions than that of GH animals. Piglets born in GH showed lower cortisol differences and fought less and for shorter periods compared to FC and FF piglets. Piglets weaned to w-f pens showed greater cortisol changes and fought significantly longer than piglets in conv pens. Group housing during the suckling period reduced weaning stress for piglets in terms of skin lesions, serum cortisol, and aggressive behavior. Greater space allowance (w-f vs. conv) was not beneficial with regard to the investigated parameters.

Cultivation of spring cereal mixtures (SCMs) is one of the ways to increase the yield of crops in mountainous areas of Poland. There are only a few current long-term studies on this topic. Our study aimed at analyzing yield and competitiveness as well as the economic indicators of spring cereals in pure or mixed sowings in integrated or organic crop rotations over nine years. A field experiment including pure sowings of oats, spring barley, or spring triticale and their two-component SCMs, each in two systems, organic and integrated crop rotation, was carried out in the Mountainous Experimental Station in Czyrna, Poland, in the years 2011–2019. On average, cereals in the pure sowings and mixtures yielded 18% lower in the organic rotations compared with the integrated ones. However, SCMs yielded higher than the pure sowings, and displayed a higher leaf area index and land equivalent ratio. The average gross margin without subsidies was almost two times higher in the organic crop rotations than in the integrated ones, which was influenced mainly by the cultivation of barley in pure sowing. Summing up, the cultivation of SCMs in the mountainous areas of southern Poland is advised because of both productive and economic factors.
