Published: March 2022

Background

Several live attenuated vaccines were shown to provide temporary protection against a variety of infectious diseases through stimulation of the host innate immune system.

Objective

To test the hypothesis that countries using oral polio vaccine (OPV) have a lower cumulative number of cases diagnosed with COVID-19 per 100,000 population (CP100K) compared with those using only inactivated polio vaccine (IPV).

Methods

In an ecological study, the CP100K was compared between countries using OPV vs IPV. We used a random-effect meta-analysis technique to estimate the pooled mean for CP100K. We also used negative binomial regression with CP100K as the dependent variable and the human development index (HDI) and the type of vaccine used as independent variables.

Results

The pooled estimated mean CP100K was 4970 (95% CI 4030 to 5900) cases per 100,000 population for countries using IPV, significantly (p<0.001) higher than that for countries using OPV—1580 (1190 to 1960). Countries with higher HDI prefer to use IPV; those with lower HDI commonly use OPV. Both HDI and the type of vaccine were independent predictors of CP100K. Use of OPV compared to IPV could independently decrease the CP100K by an average of 30% at the mean HDI of 0.72.

Conclusions

Countries using OPV have a lower incidence of COVID-19 compared to those using IPV. This might suggest that OPV may either prevent SARS-CoV-2 infection at individual level or slow down the transmission at the community level.
Study from microcosms and mesocosms reveals Escherichia coli removal in high rate algae ponds during domestic wastewater treatment is primarily caused by dark decay
Authors: Chambonniere Paul , Bronlund John E. , Guieysse Benoit
Published: March 2022

While high rate algal ponds (HRAPs) can provide efficient pathogen removal from wastewater, the mechanisms involved remain unclear. To address this knowledge gap, the mechanisms potentially causingEscherichia coli(E.coli) removal during microalgae-based wastewater treatment were successively assessed using laboratory microcosms designed to isolate known mechanisms, and bench scale assays performed in real HRAP broth. During laboratory assays,E.colidecay was only significantly increased by alkaline pH (above temperature-dependent thresholds) due to pH induced toxicity, and direct sunlight exposure via UV-B damage and/or endogenous photo-oxidation. Bench assays confirmed alkaline pH toxicity caused significant decay but sunlight-mediated decay was not significant, likely due to light attenuation in the HRAP broth. Bench assays also evidenced the existence of uncharacterized ‘dark’ decay mechanism(s) not observed in laboratory microcosms. To numerically evaluate the contribution of each mechanism and the uncertainty associated,E.colidecay was modelled assuming dark decay, alkaline pH induced toxicity, and direct sunlight-mediated decay were independent mechanisms. The simulations confirmedE.colidecay was mainly caused by dark decay during bench assays (48.2–89.5% estimated contribution to overall decay at the 95% confidence level), followed by alkaline-pH induced toxicity (8.3–46.5%), and sunlight-mediated decay (0.0–21.9%).

Published: March 2022

Background

A majority of non-invasive prenatal screening studies determining fetal RhD status have been tested on Caucasian and Asian populations, but limited or no studies have been conducted on the Ethiopian population. In the current study, we carried non-invasive prenatal screening of fetal RHD genotype in selected RhD negative Ethiopian pregnant women.

Methods

Cell-free DNA was extracted from the plasma samples of 117 RhD pregnant women between 9 and 38 weeks of gestation. Fetal RHD genotypes were detected by targeting exons 5, 7 and 10 of the RHD gene by using real-time PCR assay. RHD genotypic results were confirmed by neonatal cord blood serology.

Results

Fetal RHD genotyping was conclusive in all 117 subjects. RHD genotype was correctly predicted in 115 of 117 cases, thus the test yielded 98.3% accuracy (95%CI: 97.3–99.1%). Among 115 cases, 105 were genotyped as RHD positive and 12 were genotyped as RHD negative. The sensitivity and specificity of the test were 99.1% (95% CI: 94.8–99.9%) and 91.7% (95%CI: 61.5–99.7%) respectively. The negative and positive predictive values were 99.9% (95%CI: 99.2–99.9%) and 54.0% (95% CI: 15.2–88.4%) respectively. SRY genotyping results were in complete concordance with fetal sex.

Conclusion

Multi exon targeted non-invasive prenatal screening test for fetal RhD determination exhibited high accuracy and sensitivity. A confirmatory study with a bigger size of study subjects is warranted before enabling clinical implementation.
Association between osteoporosis and periodontal disease among menopausal women: The 2013–2015 Korea National Health and Nutrition Examination Survey
Authors: Lee Yunhee
Published: March 2022

Background

This cross-sectional study aimed to investigate the association between osteoporosis and periodontal disease among Korean menopausal women, as well as the association between osteoporosis and periodontal disease according to duration after menopause.

Methods

Of a total of 22,948 subjects who participated in the Korea National Health and Nutrition Examination Survey, from 2013 to 2015 the final study population was limited to 2,573 subjects with no missing values. The subjects were divided into two groups, normal bone mineral density (BMD) and osteoporosis, according to the T-score obtained from bone densitometry. Scores of ≥ 3 points for the community periodontal index of treatment needs were reclassified as periodontal disease. Moreover, after stratification of the variable ‘duration after menopause’ into 0–4, 5–9, and ≥10 years, binary logistic regression analysis was performed to investigate the association between osteoporosis and periodontal disease according to the duration after menopause.

Results

There was an association between osteoporosis and periodontal disease. The osteoporosis group had an adjusted odds ratio [OR] of 1.25 (95% confidence interval [CI]: 1.00–1.56) for periodontal disease compared to the normal BMD group. Of note, the osteoporosis group in the menopausal transition stage (0–4 years after menopause) showed an adjusted OR of 2.08 (95% CI: 1.15–3.77) for developing periodontal disease.

Conclusions

Osteoporosis was associated with periodontal disease and the association was strongest among women in the menopausal transition stage, 0–4 years after menopause. Oral health promotion, including regular oral examination and oral hygiene care, is particularly useful for menopausal transition women with osteoporosis.

Published: March 2022

Isoflavonoids with various structural elements show a promising potential effect on central nervous system activities. Despite their favorable medicinal properties, the pharmacokinetic characteristics of this thoroughly investigated group of natural phenolics have only been described to a limited extent. Regarding the lack of information about the BBB permeability of isoflavones, isoflavanones, and pterocarpans found in Ononis species, the aim of our study was to investigate their physico-chemical properties influencing their absorption and distribution. Furthermore, we aimed to characterize the possible MAO-B inhibiting features of Ononis isoflavonoids in silico. Octanol-water partitioning and BBB-PAMPA permeability of formononetin, calycosin D, onogenin, sativanone, medicarpin and maackiain were assessed for the first time in our study. The log P values ranged from 2.21 to 3.03 and log D7.4 values from 2.48 to 3.03, respectively, indicating optimal polarity for BBB permeation. The results of PAMPA-BBB expressed as log Pe values fell between -5.60 and -4.45, predicting their good permeation capability as well. The effective permeability values showed structure-dependent differences, indicating that the pterocarpan type skeleton was the most preferred type, followed by isoflavanones, then isoflavones. The methoxy or methylenedioxy substitution of the same skeleton did not influence the permeability significantly, contrary to an additional hydroxyl group. Membrane retention showed a similar structure dependent pattern to that of effective permeability, ranging from 16% to 70%. For the identification of volumes of chemical space related to particular biological activities the ChemGPS-NP framework was used. The MAO-B inhibitory potency and selectivity were also predicted and validated. Based on our results, MAO-B inhibitory potency could be predicted with good precision, but in the case of selectivity, only the direction could be concluded (favors MAO-B or MAO-A), not the magnitude. Our finding reflects that Ononis isoflavonoid aglycones show an excellent fit with the suggested parameters for BBB permeability and this is the first study to confirm the highly favorable position of these natural products for MAO-B inhibition.

Published: March 2022

Apicomplexa are obligate intracellular parasites responsible for major human infectious diseases such as toxoplasmosis and malaria, which pose social and economic burdens around the world. To survive and propagate, these parasites need to acquire a significant number of essential biomolecules from their hosts. Among these biomolecules, lipids are a key metabolite required for parasite membrane biogenesis, signaling events, and energy storage. Parasites can either scavenge lipids from their host or synthesize them de novo in a relict plastid, the apicoplast. During their complex life cycle (sexual/asexual/dormant), Apicomplexa infect a large variety of cells and their metabolic flexibility allows them to adapt to different host environments such as low/high fat content or low/high sugar levels. In this review, we discuss the role of lipids in Apicomplexa parasites and summarize recent findings on the metabolic mechanisms in host nutrient adaptation.

Recently, automotive industries are encouraging to use a virtual reality - head mounted display (VR-HMD) as a drive/flight simulator. As a background, there is an advantage that such devise can display parameters such as speed meter and GPS marker in the user’s viewing zone and can perform adjustments in test operation. However, even if there were advantages, the effect obtained by training is absolutely needed. Among them, improvement of safety during driving is the most important effect in this field. In this work, we add the VR video image withdifferences spatially and timely led by professional to the one for real time VR video image. We discuss the visual performance of the images obtained by this from the side of view of safety.
Assessing the public perceptions around covid-19 vaccine within the University of Eldoret community using WhatsApp focus groups.
Authors: Dena Simon
Published: March 2022

Infection caused by viruses can only be eradicated through the formulation of a vaccine that primes the body to fight the virus. No recent study exists on the attitudes and perceptions of students on the COVID-19 vaccine. Without information on the prevailing COVID-19 vaccine, set objectives towards the realization of a healthy nation will be unmet. The current research employed an exploratory survey design. The study mostly used stratified random sampling. Different age groups were sampled. Online questionnaires were administered through Whatsapp social media platforms. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 20 and excel 2013 spreadsheet. Data were analyzed using descriptive statistics. The majority of respondents were male (63.0%) and female (37.0%). The total number of respondents who were willing to take up the Covid-19 Vaccine was 84 of which 33 were females (16.5%) and males were 51(25.5%). In vaccine knowledge 110 (56.0%) of responses were positive which indicated most respondents knew about the vaccine center while 85 (44.0%) of the respondents did not know about Vaccine centers. Respondents who answered the online questionnaire demonstrated their knowledge of vaccines. Both males and females who total 160 (80%) knew the importance of a vaccine while 23 (11.5%) clearly acknowledge they had no idea of the role a vaccine plays, 12 (6%) were uncertain about the issue of vaccines. The 5 respondents (2.5%), did not answer the question on knowledge of vaccines. A large significant population fully trusted the pharmaceutical in vaccine production. Only 173 (86.5%) had not been vaccinated while 23 (11.5%) had been vaccinated. The responses showed that 44(22.0%) respondents had indeed been influenced by their religious leaders not to be vaccinated, 77(38.5%) maintained that their religious leaders entirely let them make a decision of whether to take the Vaccine or deal away with it. 40 (23.0%) respondents agreed to conspiracies revolving around Covid 19. Research recommends developing social-media platforms that would ensure education on vaccination and immunization within the population. Educating both genders with emphasis on females to impact them with the necessary knowledge on vaccines.
Higher Quality Colonoscopy: Worth the Wait?
Authors: Gawron Andrew J. , Dominitz Jason A.
Published: March 2022

To meet the high demand for colonoscopy, the Veterans Health Administration often refers veterans to community practices. Petros et al. compared colonoscopy quality at a Veterans Affairs Medical Center with that of local community practices. Although community providers performed more timely colonoscopy than the Veterans Affairs medical center (mean 25 days earlier), colonoscopy quality was significantly lower for other important quality metrics, including adenoma detection, advanced adenoma detection, adenomas per colonoscopy, and appropriate surveillance recommendations. This study highlights the need for continued efforts to assure high-quality colonoscopy in all settings.

Published: March 2022

Introduction:

Gastroparesis is a serious medical condition characterized by delayed gastric emptying and symptoms of nausea, vomiting, bloating, fullness after meals, and abdominal pain.

Methods:

To ascertain the genetic risk factors for gastroparesis, we conducted the largest thus far whole-genome sequencing study of gastroparesis. We investigated the frequency and effect of rare loss-of-function variants in patients with both idiopathic and diabetic gastroparesis enrolled in a clinical study of gastroparesis.

Results:

Among rare loss-of-function variants, we reported an increased frequency of a frameshift mutation p.Leu202ArgfsTer105, within the motilin receptor gene, variant rs562138828 (odds ratio 4.9). We currently replicated this finding in an independent large cohort of gastroparesis samples obtained from patients participating in the ongoing phase III gastroparesis clinical study.

Discussion:

Motilin receptor is an important therapeutic target for the treatment of hypomotility disorders. The identified genetic variants may be important risk factors for disease as well as may inform treatments, especially those targeting motilin receptor.

Published: March 2022

INTRODUCTION:

Antiprogrammed cell death protein-1 (PD-1) immunotherapy has substantially broadened in scope for the treatment of colorectal cancer (CRC). However, comparative safety, efficacy and survival outcome of anti-PD-1 therapy in CRC patients with and without hepatitis B virus (HBV) infection remain unclear.

METHODS:

This multicenter, retrospective cohort study included 180 advanced-stage CRC patients with available serological markers for HBV infection treated with anti-PD-1 therapy at the Sixth Affiliated Hospital, Sun Yat-sen University and Sun Yat-sen University Cancer Center between December 2016 and December 2019. A propensity score-matched analysis was performed to compare the safety, efficacy, and survival outcome between HBV and non-HBV groups.

RESULTS:

The incidences of deficient mismatch repair and metastatic disease were significantly different between HBV and non-HBV groups (both P < 0.05). After propensity score-matched analysis, any grade immune-related adverse events and grade ≥ 3 immune-related adverse events were 47% vs 38% (P = 0.25) and 5% vs 6% (P = 1.0) between HBV and non-HBV groups, respectively. The overall response rate was 39% with 17 complete responses and 13 partial responses for the HBV infection cohort and 39% with 11 complete responses and 19 partial responses for the non-HBV infection cohort (P = 1.0). Two-year progression-free survival rates were 38% vs 40% (P = 0.596) and 2-year overall survival rates were 55% vs 63% (P = 0.401) for HBV vs non-HBV infection cohorts.

DISCUSSION:

The incidences of toxicity, efficacy and survival outcome were similar between patients with HBV infection and non-HBV patients receiving anti-PD-1 therapy, which supports to include CRC patients with HBV in clinical trials of anti-PD-1 therapy.

Published: March 2022

The available taxonomic literature for Cordia species in Argentina (Cordiaceae, Boraginales) does not reflect the currently known phylogenetic relationships of the lineage. Recent studies evidence that Patagonula americana and Saccellium lanceolatum nest within Cordia, and that five species traditionally circumscribed under Cordia should be considered within Varronia. In this context, the present contribution provides an updated taxonomic treatment of Cordia in Argentina. Complete synonymy for all accepted species is provided, and morphological descriptions, geographic distribution maps, common names, an identification key, uses, illustrations, photographs and conservation status. Additionally, a lectotype is designated for the name Cerdana alliodora and Cordia trichotoma is recorded for the first time in Formosa province.

Published: March 2022

The concept of dark heritage has been used as a concept of preserving an area or site that contains relics due to dark events in the past. The 2004 tsunami disaster that hit the city as the most affected area after the disaster has left various relics and tsunami sites that need to consider dark heritage planning. However in dark heritage planning has not yet considered aspects of local communities, especially survivors as the most affected group from the tsunami disaster. The purpose of this paper is to look at dark heritage planning that involves the community as an important aspect in the preservation of post-disaster areas as well as to find out the components and values that are considered important by the community in preserving dark heritage. The study was carried out from August 2019 to December 2019 in the post disaster area of Banda Aceh as the most affected area using a qualitative approach. This study reveals that dark heritage planning that involves communities contributes to resilience thus creating resilient communities. In addition, religion and local culture in the post disaster area are important aspects that cannot be separated for the community in sustainable dark heritage planning.

Published: March 2022

CPTED studies has been popular since 1960-1970s, however studies in Indonesian city context showed limited references. This paper identified the need of CPTED study followed a massive MRT network development in Jakarta City, as the need for re-design and city beautification to fit with the vibrant TOD urban lifestyle may create moments as well to promote CPTED implementation. The perception survey was developed to understand the perceived crime risk level among the MRT users of Bundaran HI Station. The survey conducted in two scopes of context, i.e. the TOD precinct, an area of 800 radius from the station, and inside the station itself. Finding from the TOD context showed that the maintenance and information have been the most significant but often mostly ignored. These two component may lead to under-rated other CPTED components, weaken the territorial reinforcement and natural surveillance. Out of 56 parameters, 26 parameters or almost halve have rated below 3, alarmed for a more comprehensive design and intervention at the TOD neighbourhood level that emphasizes on the implementation of CPTED principles. Finding from the Bundarin HI station context showed that under the Likert scale 1 (the lowest risk) to 5 (the highest risk), most of the CPTED rated from 4 – 5. There were a variation in the perceived security among different respondents based on gender, time pattern, location pattern, and mode chosen for station access. However, these rating differences were not significant according to the ANOVA and the t-test statistics. The chi-square test found no association between the perceived securities with the type of mode uses for station access. These preliminary findings suggested that the Bundaran HI TOD station is secured from crime risk according to perception of MRT users; therefore little variation in the rating of perceived security gave little information to draw any association with other important variables such as the mode choice for station access. However, taken the measures on wider context at the TOD precinct, the rating of CPTED consistently lower in all components, suggested the urban design and land use zoning-and transportation intervention that consider CPTED principles to be emphasizing at wider area to support the security of the station.

Published: March 2022

In this article, a new technology of surface wrapping and strengthening of expandable polystyrene (EPS) beads is proposed. Three wrapping materials including magnesium phosphate cement (MPC), ultra-high performance concrete (UHPC), and water-borne polyurethane (WPU) were evaluated. Four groups of uniaxial compression tests of EPS concrete specimens were conducted: the failure process and the characteristics of the specimens were analyzed; and the complete stress–strain equation is proposed based on these analyses. The research shows that the EPS beads were strengthened by wrapping, and the axial compressive strength of concrete is increased by 50–75%; the concrete with EPS beads wrapped by MPC and WPU has obvious brittleness; the concrete with EPS beads wrapped by UHPC has axial compressive strength close to that of EPS concrete wrapped with MPC and WPU but has a larger ductility coefficient (150%), a larger toughness coefficient (50–90% larger), a higher energy dissipation coefficient (40% larger), and larger residual stress. The proposed stress–strain model is in good agreement with the experimental results, which can accurately describe the stress and deformation characteristics of EPS concrete under uniaxial compression and has good applicability. The discovery of this study provides background knowledge for the structural analysis and design of this kind of concrete; it provides a basis for selecting EPS concrete as structural materials.

Published: March 2022

The study investigated the existing guidelines on the quality and frequency of the follow-up visits after total hip replacement surgery and assessed the level of evidence of these recommendations.

The review process was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Additional works were retrieved by direct investigation of the available guidelines of the most important orthopedic societies and regulatory agencies.

The current systematic review of the literature resulted in zero original papers, four guidelines for routine follow-up and three guidelines for special cases. Concerning the quality of evidence behind them, these guidelines were not evidence based but drafted from expert consensus.

The most important finding of this review is the large variation of recommendations in the follow-up schedule after total hip arthroplasty and the lack of evidence-based indications. Indeed, all the above-reported guidelines are the result of a consensus among experts in the field (level of recommendation class D ‘very low’) and not based on clinical studies.
Memory and postmemory in the writing of North American writers of Lithuanian descent
Authors:   , Sruoginis Laima Vincė
Published: March 2022

This dissertation analyzes five memoirs written in English by North American writers of Lithuanian descent, published between 2001 and 2017 in the United States and Canada: Painted in Words—A Memoir (2001) by Samuel Bak, The Barefoot Bingo Caller (2017) by Antanas Sileika, White Field, Black Sheep: A Lithuanian-American Life (2010) by Daiva Markelis, A Guest At the Shooters’ Banquet (2015) by Rita Gabis, and Siberian Exile: Blood, War, and a Granddaughter’s Reckoning (2017) by Julija Šukys. In their memoirs, these writers reflect on and challenge aspects of Lithuanian historical trauma (the Holocaust) and Lithuanian cultural trauma (deportations to Siberia, World War II, the postwar experience, the refugee experience, immigration). They consider the impact of those historical events on their ancestors, themselves, and their descendants. All five embarked on postmemory rite of return journeys to Lithuania after Lituania’s independence from the Soviet Union, seeking answers about family narratives. These memoirs function both as memory and postmemory narratives. In each of the memoirs, the writers explore personal narratives as narratives of culture against the backdrop of collective memory and historical and cultural trauma. Superimposed onto their individual memory narratives are explorations of familial and affiliative postmemory that are geographically, historically, and culturally distant for these writers living on the North American continent, and yet vitally important to them. There is a belatedness to these memory narratives, which in part is caused by the divisions of the Iron Curtain and Cold War politics, and in part because of the time needed to process and heal from extreme trauma (the first generation) or come to terms with inherited postmemory traumas (the second and third generations). Writing in English about Lithuania, these writers function as cultural translators who translate their postmemory experience for an audience of North American readers. Their work is representative of a growing body of literary novels, memoirs, essays, plays, and poems that explore postmemory topics related to Lithuanian cultural and historical trauma and collective memory that are written in English and published in North America by both university presses and commercial publishers.

Results of the conducted botanical surveys in the Forest-Steppe part of Zhytomyr Region are provided. Nine alien taxa (mainly xenophytes) new for the flora of the Right Bank Forest-Steppe have been identified: Allium altissimum, Amaranthus deflexus, Aphanes arvensis, Artemisia umbrosa, Crataegus sanguinea, Epilobium pseudorubescens, Erigeron strigosus, Polygonum calcatum, and Silene coronaria. Localities of these species are described and botanical-geographical comments are provided for most of taxa. There are also 64 taxa newly reported for the Forest-Steppe part of Zhytomyr Region, of which 31 are native plants, 32 – alien plants, and 1 species of unidentified origin. Twelve taxa are rare and protected at different levels. Invasive plants in need of monitoring are identified among newly reported species. According to the new data, flora of the Forest-Steppe part of Zhytomyr Region includes more than 1320 taxa of vascular plants. An important result was the discovery at the border of Zhytomyr Polissya and the Right Bank Forest-Steppe of localities of five expanding species of the genus Rubus with predominantly Central European ranges: R. bertramii, R. gracilis, R. hirtus, R. montanus, and R. plicatus. Expansion of these species of blackberries in the eastern direction within the territory of Northern Ukraine is associated with natural migration and is probably caused by the gradual climate warming.

A literatura especializada tem acentuado a dificuldade de realização do potencial da internet para o desenvolvimento da conversação política com argumentação, tolerância e reciprocidade, qualidades desejáveis à deliberação pública, tal como ela tem sido idealizada em termos habermasianos. Apresentamos os resultados de pesquisa empírica sobre páginas oficiais de juventudes partidárias no Facebook que empregou análise de conteúdo para diferenciar as finalidades das postagens e distinguir características dos comentários, com o objetivo geral de verificar a qualidade de espaços que, por sua vinculação às instituições políticas formais, poderiam exibir características promissoras para a conversação política. Os resultados indicam a prevalência de uso da rede pelos partidos para divulgação de serviços públicos e promoção institucional, em detrimento das formas de diálogo. Nos comentários, foram identificadas características que sugerem o efeito de filtros-bolha e câmaras de eco, que tendem a dificultar o surgimento de condições propícias à conversação política.

Published: March 2022

Corn is widely used as a source of starch in the food, pharmaceutical, paper, mining and construction industries.This starch is usually obtained after the cleaning process, and corn germ, fiber and protein are also produced. It is used in theproduction of biodegradable plastic bags, medicines, paper, corrugated cardboard, detergents, paints, diapers, cosmetics,glue, surfactants and agrochemicals. Corn is the most important grain in the world. After all, in addition to the highest consumptionof all grains, corn is also a universal product from which you can get fuel, electricity and household goods. Thismeans that by increasing the volume of corn processing, it is possible to go beyond the agricultural sector and create goodswith high added value. Growing corn for grain allows better use of agricultural machinery due to the later dates of sowingand harvesting. Valuable properties of corn cause its consistently high demand on the world market.Corn grain processing is part of the technological lines that are part of cereals. The main equipment that ensureshigh quality products are impact centrifugal crushers.Analysis of the operation of the impact-centrifugal crusher revealed the possibility of its operation in a wide range ofchanges in design parameters. The oretical aspects of the dependences of crusher productivity, which basically take its designparameters and modes, include: rotational speed of grinding discs, disc diameter, disc tooth length, thickness, and propertiesand parameters of grain material.As a result of the conducted researches the possibility of increase of qualitative characteristics of the processedproducts, and also productivity of the shock-centrifugal crusher is defined.To increase productivity, it is proposed to implement two options. On the one hand to make the rotational speed ofthe adjustable working body, on the other hand to increase the sizes of diameters of working disks, taking into account a designof the crusher for corn grain, having provided productivity of the crusher.The purpose of this work is to increase the efficiency of the grain crusher, which is part of the preparation of grainfor grinding, to ensure the reliability of the machine, its productivity, improve the quality of finished products by implementingautomation based on SMART-technology, defined as self-control technology and reporting. This technology provideslong-term archiving of the received data that allows the dispatcher to watch work of the corresponding equipment, reactingby means of the IT- service program.

Published: March 2022

The article describes that budgerigar is one of the most popular domestic birds. Budgerigars have become so popular thatthey have "overtaken" even canaries in this regard.The budgerigars eat the same as other parrots. They like nuts, millet, oats and wheat. Undoubtedly, they need fruits andvegetables for development and growth. They like to indulge in slices of tangerine and lemon, pears and apples.It is advisable to use pelleted feed to meet all the needs of parrots in nutrients and biologically active substances. These aresmall dry pellets balanced in the amount of nutrients, with the addition of important essential amino acids and vitamins. Pelleted feedis made from a mixture of cereals, vegetables, mineral and vitamin supplements. No additional synthetic vitamins or supplements arerequired when feeding pelleted feed.Parrots are popular in the world. The budgerigars rank 4th in Ukraine in popularity among pets after cats and dogs.The pet feed market has existed for about 20 years in Ukraine, so in terms of volumes it lags far behind the world's leadingmarkets. At the same time, the Ukrainian pet feed market is characterized as fast-growing according to analysts at Euromonitor International.It is considered that Ukraine is in 8th place in the TOP-10 fast-growing pet feed markets. However, the Ukrainian marketis dominated by foreign producers feed from countries such as Hungary, Russia, the United States, France and others.The following brands are among the budgies feed in Ukraine: «Lori», «Nature», «Maxi», «Special One», etc.Proper feeding of budgies does not cause much trouble nowadays. Parrots like solid feed consisting of a mixture of cereals,and soft feed from fruits, vegetables and protein foods.Pellets are a solution for parrot owners who haven’t time to closely monitor their pet's diet. The pellets contain choppedfruits, vegetables and other useful components (depending on the brand and product). They can be given to the bird if it is not possibleto get fresh food.The pellets have advantages and disadvantages. The disadvantages include the difficult transition to a such diet, as theparrot does not understand that it is food. Advantages: the composition of pellets is enriched with essential and non-essential aminoacids and vitamins. Pelleted feed is well balanced for the daily diet and haven’t husks as an additional positive effect.The cost of raw materials for the developed pelleted feed is on average 10 UAH per 1 kg. It is advisable to produce pelletedfeed for budgies, because the low cost and high quality will attract owners of budgies.
How Do Management Students Perceive Their Cultural Intelligence?
Authors: Dudek Alicja
Published: March 2022

Objective: The ability to communicate remains one of the most sought-after qualities in university graduates. The globalisation and internationalisation of companies has increased the importance of capabilities allowing for effective cooperation in a culturally diverse environment. This study draws on the theoretical framework of cultural intelligence (cultural quotient – CQ) and utilises the Cultural Intelligence Scale (CQS) to examine the cultural intelligence of students at the Cracow University of Economics.Research Design & Methods: The survey instrument consisted of two sections. The first describes the 20-statement Cultural Intelligence Scale presented by Ang et al. in 2007. A seven-point Likert scale (strongly disagree = 1, strongly agree = 7) was used to rate each statement. The second section presents demographic information and some aspects of the respondents’ international experience (studying abroad and projects promoting international collaboration, for example).Findings: The results show that, of all of the elements constituting CQ, students possess the lowest levels of cognitive CQ.Implications / Recommendations: The literature review allows for a couple of conclusions. First, in order to enhance the CQ, particularly the cognitive component, international experience is crucial. The university should therefore encourage students to participate in exchange programmes and consider increasing the number of such programmes made available to students.Contribution: This paper deepens the understanding of the CQ, especially the areas that should be prioritised for improvement by students who will soon start to work in a culturally diverse environment.
Nowe wymagania w zakresie jakości usług wodociągowych dotyczące strat wody

Objective: Directive 2020 / 2184 on the quality of drinking water and the European Green Deal introduce new requirements for assessing the quality of water services and the need to reduce water leakage. The main purpose of the article is to compare the methods of determining water losses used in Poland with international standards and to determine the readiness of Polish water supply systems to implement mandatory leakage estimation standards.Research Design & Methods: The article presents a review of the literature on water loss assessment methods in Poland and abroad. Data on water losses in 11 water supply systems were presented, based on the information from the Central Statistical Office and the literature. Based on the data, a comparative analysis of selected entities was carried out.Findings: With a ranking of water utilities created, the impact of input data and the adopted calculation methodology on the position of a given entity in the ranking were analysed. The assumptions made for the calculation of the indicators and the choice of the evaluation method are shown to be important in the assessment of the entities.Implications / Recommendations: Comparing the scope of data collected at the national level and the requirements for international standards, it can be concluded that in Poland these data are not sufficient to calculate the value of the ILI (Infrastructure Leakage Index). The ILI is known in Poland, but its application is limited to the local level. The introduction of new requirements for the calculation of ILI at the national level will require the implementation of methods for collecting large amounts of data from many water utilities.Contribution: Due to the important role water utilities play, the level of infrastructure maintenance in supply systems must be constantly controlled. One of the basic indicators for assessing the condition of the water supply network is water loss. The conclusion from the article can be used by water operators to better evaluate their systems. The results of the analysis indicate the need for further research and the development of new methods of assessing water supply systems. The research contributes to the development of several scientific disciplines: environmental engineering, mining and energy management and quality studies.
