CONDITIONS FOR DE VELOPMENT OF ENTREPRENEURSHIP IN REGIONS OF VISEGR AD GROUP COUNTRIES

1 The aim of this paper is to analyse and evaluate the directions of changes in the development of entrepreneurship in the regions of the Visegrad Group countries, i.e., the Czech Republic, Poland, Slovakia and Hungary, in the period 2004–2018. We carried out research using an entrepreneurship model based on the Global Entrepreneurship Monitor (GEM) methodology. The literature analysis made it possible to formulate the main research hypothesis, which states that the factors of entrepreneurship development in this period had a different impact on the establishment of enterprises at the level of regions in the Visegrad Group countries. Assigning individual regions of these countries to entrepreneurship classes in the investigated years showed significant differences, which means that the NUTS 2 regions of the Visegrad Group countries differ significantly in terms of entrepreneurship development conditions.

Microbial load of healthcare wastes in Aba Metropolis, Abia State

Introduction: Healthcare waste is the total waste both solid and liquid from healthcare establishment and laboratories. A hospital produces waste by giving their services to the patients. Purpose: This study examined the microbial load of waste from selected healthcare facilities in Aba metropolis, Abia State. Methodology: Tenfold serial dilution was used for processing of all the samples. After the dilutions, exactly 0.5ml of each the sample was planted on the media using the spread plate method and evaluated using the standard microbiological techniques. Results: The viable count (TVC) ranged from 1.0×10cfu/g to 0.3×10cfu/g, coliform count (TCC) ranged from 0.4×10 cfu/g to 4.2×10 cfu/g, staphylococcal count (TSC) ranged from 1.0×10 cfu/g to 1.4×10 and fungal counts ranged from 2.0×10 cfu/g to 0.8×10cfu/g in the microbial count of various waste samples within the Aba metropolis, Abia State. The laboratory waste had the highest microbial counts, followed by the Out-patient department waste and the least was the pharmaceutical waste. The microorganisms isolated from the hospital wastes were Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Aspergillus niger, A. Fumigatus, Candida albicans and among others. Unique contribution to theory, practice and policy: This research has revealed that healthcare waste contained pathogens with high microbial load densities, suggesting that the hospital wastes may pose a major health and environmental threat, if not properly managed. The study recommends that, the government should ensure that there is a policy on hospital waste management in line with recommended international best practices, which should be monitored and enforced.
Between Hemse and Mästermyr Craft interpretations of two archaeological findings from Gotland

The distance between Hemse church and the fields of Mästermyr on the Swedish Island of Gotland is about eight kilometers. The distance or rather the proximity between these two places is given importance in this filmed research article. In the 1930s, a farmer found a wooden chest in Mästermyr containing hundreds of forged tools and other artefacts. During a restoration of the Romanesque Hemse church in the 1890s, reused parts of a stave church were discovered in the wooden floor. The hypothetical question that is investigated in this study is whether the tools from Mästermyr were used in the construction of Hemse stave church in the early 1100’s? This filmed article analyzes and compares the traces of toolmarks in Hemse stave church and the woodworking tools from the Märstermyr finding. Through a forensic examination involving 3D scanning with structured light, 3D printing and reconstruction of tools and woodworking procedures, it is revealed that several toolmarks in the stave church correspond to the characteristics of woodworking tools in the Mästermyr find. The tool's shape, dimensions and mode of operation are traced in its negative imprint in the stave church’s oak wood.

Impact of Mindfulness on Social Media Promotions for FMCG Products - An Exploratory Study

In a world full of buzz and surface interactions, consumers seek more depth and meaning. This intensity can also come from a very different angle, in the form of mindfulness. Consumers think about and take responsibility for the ethical status of brands they buy and support. The shopping that they do is now more mindful and not just throwing items into basket without thinking twice. Companies always desire to follow consumerism orientation that portrays consumers as consuming anything and everything. This trend is changing now. More and more consumers have started to consume and spend just apt to their needs. Even in this age of internet, they feel paying through cash rather than card is a better option. It is something tangible and they do not want to hand more of it than is strictly necessary. In case of FMCG products, they now prefer to go to nearby markets where they get better value for money rather than big names. This is an exploratory study to determine influence of Mindfulness on social media promotions for FMCG products. Main purpose is to determine whether the promotion on social media platform helps mindful consumers in decision-making. Study also gauges whether social media promotion persuades them to buy a product that does not have much use to them by making them less mindful. This study assists companies to decide what type of promotion should be done to attract mindful consumers and to check whether the money spent on social media promotion generates revenue from mindful consumers. Study also guides marketing managers to make changes in its promotional methods to attract customers with different preferences. Above all, the study supports that market can be segmented based on mindfulness and give companies more ammunition to target customers.
DFT Studies of the Toxicity of Para-Substituted Ortho-Benzoquinones

Toxicity descriptors based on Cu(II) coordination ability of para-substituted ortho-benzoquinones and subsequent O → Cu electron density transfer are introduced. Geometries of quinones and of their Cu(II) complexes are optimized using DFT treatment. The transferred electron density is evaluated using the copper charge or the Laplacian of electron density at the Cu-O bond critical points. The toxicity of quinones with electron-withdrawing substituents is much more sensitive to the extent of electron density transfer. Quinone O atoms exhibit equal trends for electron-donating substituents only.
Smart Vehicle Parking System Using Computer Vision and Internet of Things (IoT)

Internet of Things is the interconnectivity between things, individuals and cloud administrations by means of web, which empowers new plans of action. Because of these exchanges, immense volumes of information are smartly created and is shipped off cloud-based server through web; the information is being handled and broken down, bringing about significant and convenient activities for observing the car parking. The serious issue that is arising currently at a worldwide scale and developing dramatically is the gridlock issue brought about by vehicles. A worldwide scale and developing dramatically is the gridlock issue brought about by vehicles. Among that, finding a better parking sparking space in urban areas has become a major problem with an increase of the numbers of vehicles on a daily bases. Therefore, making it difficult in having a better and safe parking spot. The system proposes an intelligent smart parking system using computer vision and internet of things. The proposed system starts by acquiring a dataset. The dataset is made up images of various vehicles, which was collected from the faculty of science car park at the Rivers State University, Port Harcourt, Rivers State Nigeria. We proposed two methods for vehicle/parking slot detection. The first method is the use of convolution neural network algorithm which is used with a haar cascade classifier in detection of multiple vehicles in a single picture and video, and put rectangular boxes on identified vehicles. This first method obtained an accuracy of 99.80%. In the second method, we made use of a Mask R-CNN, here we download a pre-trained model weights which was trained on a coco dataset to identify various objects in videos and pictures. The Mask R-CNN model was used to identify various vehicles by putting a bounding box on each of the vehicle detected, but one of the problem of the Mask R-CNN is that it quite slow in training, and it could not really detect all vehicles tested on a high quality high definition video. In summary our, trained model was able to detect vehicles and parking slot on high quality video and it consumes lesser graphic card.
MicropyramidVerticalUltravioletGaN / AlGaNMultipleQuantum Wells LEDs on Si ( 111 )

Micropyramid vertical GaN-based ultraviolet (UV) light-emitting diodes (LEDs) on Si(111) substrate have been fabricated by selective area growth to reduce threading dislocations and the polarization effects. )ere is no-light emission at the bottom and six planes of the pyramid at lower current due to the leakage current and nonradiative recombination of the dislocation at the bottom and the 90° threading dislocations (TDs) at six planes of the pyramid, and the top of the pyramid is the high-brightness region. )e micropyramid UV LED has a high optical output intensity under a small current injection, and the series resistance of unit area is only a quarter of the conventional vertical LEDs, so the micropyramid UV LED would have a high output power under the drive circuit. )e reverse leakage current of a single micropyramid UV LED is 2 nA at −10V.
Fabrication of smartphone-based colorimetric device for detection of water leaks

Water supply systems play a critical role in providing quality drinking water to household consumers, for agricultural purposes, and industrial usage (Cosgrove and Rijsberman, 2014). However, water leakage and water loss from burst pipes pose a serious threat to uninterrupted water supply (Yazdekhasti et al., 2018). This has a dire consequence to the quality of life, hygiene and health of hundreds or even thousands of inhabitants (Cosgrove and Loucks, 2015). Moreover, water is one of the vital and scarce resources of life (Pfister et al., 2017). In South Africa, this water scarcity is made even worse by the amount of municipality-supplied water being lost through leaking or burst pipes and dripping taps. This is highly concerning from an economic perspective, as the leaks and pipe bursts cost municipalities a lot of money. For instance, it is estimated that water loss due to burst pipes or water leakages costs eThekwini Municipality approximately 400 million ZAR annually (Thakur et al., 2019). Equally concerning, the recent water scarcity and drought experienced in the Western Cape (Cassim, 2018)called for an urgent need for effective management of water supply in South Africa.
WEED VEGETATION STRUCTURE IN AN AREA OF ORGANIC ACEROLA CULTIVATION , PARNAÍBA , PIAUÍ , BRAZIL

This study aimed to identify and quantify the weed species in an area of organic acerola cultivation in the Distrito de Irrigação dos Tabuleiros Litorâneos do Piauí (DITALPI) in Parnaíba, Piauí, Brazil. Phytosociological sampling was completed in the rainy season, before the farmers adopted management techniques for the plants. Thirty plots of 0.25 m2 were sampled. The plots were located between crop rows, which consisted of herbaceous-subshrub plants. The absolute and relative covers and the absolute and relative frequencies of each species were calculated based on the occurrence and cover of each species. In total, 25 species comprising 13 families were registered, among which the Poaceae family that presented the largest number of species. Commelina benghalensis occurred the most frequently overall. Shannon’s diversity index (H’) and evenness were calculated as 2.30 nats ind-1 and 0.69, respectively. Five species accounted for 79.33% of absolute cover at DITALPI. The species were distributed heterogeneously within the field, and Commelina benghalensis, Urochloa plantaginea, Panicum maximum, Amaranthus spinosus, Cynodon sp. , and Cyperus aggregatus were the species most likely to infest the acerola crop. As DITALPI is an area of organic cultivation, understanding these species is essential to help farmers select the best form of control.
A pricing model for water rights trading between agricultural and industrial water users in China

This paper presents a pricing model developed for the Chinese water rights trading market. The model focuses on the transfer of water rights from irrigators to industrial users in areas with limited water resources. Water rights trading is an efficient means of allocating water resources, and the price plays an important role in this market. At present, China lacks formal mechanisms in place for water rights pricing. Therefore, an integrated pricing model is built for situations when agricultural users implement water conservation measures and sell water rights to meet industrial water demand. The model accounts for project construction costs, operation and maintenance costs, renewal and reconstruction expenses, irrigation frequency compensation, and the economic cost of ecological damage. The marginal value of water rights to the industrial water user is also quantified on the basis of the production function accounting for water inputs. The pricing model is applied to an example of water rights trading between irrigators and industrial users in an agricultural area on the Yellow River near Ordos in Inner Mongolia.
Efficient adsorption of lead (II) and copper (II) from aqueous phase using oxidized multiwalled carbon nanotubes/polypyrrole composite

ABSTRACT Polypyrrole coated oxidized multiwalled carbon nanotubes (oMWCNT/Ppy) were applied to determine the adsorption characteristics of Pb(II) and Cu(II) from their aqueous solutions. Structural and morphological characterization studies using scanning electron microscopy, thermogravimetric analysis, Fourier transform infrared and Raman spectroscopy showed successful preparation of the oMWCNT/Ppy composite. The influence of pH, contact time, and initial metal ion concentration on the adsorption of Pb(II) and Cu(II) was studied. The adsorption processes fitted well with Langmuir isotherm and pseudo-second-order kinetic models. The maximum adsorption capacities for Pb(II) and Cu(II) were determined as 26.32 and 24.39 mg/g, respectively. Desorption studies indicated that the oMWCNT/Ppy composite could be reused for five cycles with minimum loss of its initial adsorption capacity.
Growth, secondary metabolite production, and in vitro antiplasmodial activity of Sonchus arvensis L. callus under dolomite [CaMg(CO3)2] treatment

Malaria is still a global health problem. Plasmodium is a single-cell protozoan parasite that causes malaria and is transmitted to humans through the female Anopheles mosquito. The previous study showed that Sonchus arvensis L. callus has antiplasmodial activity. Several treatments are needed for callus quality improvement for antimalarial compound production. This study aimed to examine the effect of dolomite [CaMg(CO3)2] on growth (morpho-anatomical structure and biomass), secondary metabolite production, and in vitro antiplasmodial activity of S. arvensis L. callus. In this study, leaf explants were grown in Murashige and Skoog medium with a combination of 2,4-dichlorophenoxyacetic acid (2,4-D, one mg/L) and 6-benzyl amino purine (BAP, 0.5 mg/L) with dolomite (50, 75, 100, 150, and 200 mg/L). The 21 days callus ethanolic and methanolic extract were analyzed by gas chromatography-mass spectrometry (GC-MS) and thin-layer chromatography (TLC). The antiplasmodial test was performed on a blood culture infected with Plasmodium falciparum strain 3D7 using the Rieckmann method. The results showed that dolomite significantly affected callus growth, metabolite profile, and in vitro antiplasmodial activity. Dolomite (150 mg/L) showed the highest biomass (0.590 ± 0.136 g fresh weight and 0.074 ± 0.008 g dry weight). GC-MS analysis detected four compounds from callus ethanolic extract. Pelargonic acid, decanoic acid, and hexadecanoic acid were major compounds. One new terpenoid compound is based on TLC analysis. S. arvensis L. callus has antiplasmodial activity with the IC50 value of 5.037 μg/mL. It was three times lower than leaf methanolic extract and five times lower than leaf ethanolic extract.
The impact of health worker absenteeism on patient health care seeking behavior, testing and treatment: A longitudinal analysis in Uganda

Introduction Absenteeism of frontline health workers in public sector facilities is widespread in low-income countries. There is little quantitative evidence on how health worker absenteeism influences patient treatment seeking behavior, though low public sector utilization and heavy reliance on the informal sector are well documented in low-income settings. Methods Using a unique panel dataset covering health facilities and households over a 10-month period in Uganda, we investigate the extent to which health worker absenteeism (defined as zero health workers present at a health facility) impacts patient care seeking behavior, testing, and treatment. Results We find high rates of health worker absenteeism at public sector health facilities, with most of the absenteeism occurring at lower level public health clinics. On average, no health worker was present in 42% of all days monitored in lowest level public health clinics, whereas this number was less than 5% in high level public hospitals and private facilities. In our preferred empirical model with household fixed effects, we find that health worker absenteeism reduces the odds that a patient seeks care in the public sector (OR = 0.65, 95% CI = 0.44–0.95) and receives malaria testing (OR = 0.73, 95% CI = 0.53–0.99) and increases the odds of paying out-of-pocket for treatment (OR = 1.41, 95% CI = 1.10–1.80). The estimated differences in care-seeking are larger for children under-five than for the overall study population. Conclusions The impact of health worker absenteeism on the quality of care received as well as the financial burden faced by households in sub-Saharan Africa is substantial.
The absence of fans removes the home advantage associated with penalties called by National Hockey League referees

The COVID-19 pandemic has had a major impact on professional sports, notably, forcing the National Hockey League to hold its 2020 playoffs in empty arenas. This provided an unprecedented opportunity to study how crowds may influence penalties awarded by referees in an ecological context. Using data from playoff games played during the COVID-19 pandemic and the previous 5 years (n = 547), we estimate the number of penalties called by referees depending on whether or not spectators were present. The results show an interaction between a team’s status (home; away) and the presence or absence of crowds. Post-hoc analyses reveal that referees awarded significantly more penalties to the away team compared to the home team when there is a crowd present. However, when there are no spectators, the number of penalties awarded to the away and home teams are not significantly different. In order to generalize these results, we took advantage of the extension of the pandemic and the unusual game setting it provided to observe the behavior of referees during the 2020–2021 regular season. Again, using data from the National Hockey League (n = 1639), but also expanding our sample to include Canadian Hockey League games (n = 1709), we also find that the advantage given to the home team by referees when in front of a crowd fades in the absence of spectators. These findings provide new evidence suggesting that social pressure does have an impact on referees’ decision-making, thus contributing to explain the phenomenon of home advantage in professional ice hockey.
Quantum-chemical study of molecular structure and relative stability of trans and cis isomers of model anilide derivatives

Abstract Derivatives of anilide were studied systematically by the density functional theory (DFT) using the B3LYP hybrid functional and the 6-311+G(3df,2p) basis set. Characteristic frequencies of N-H and C=O stretching modes for cis and trans conformers distinguishing were compared with available experimental and theoretical data. Effect of substitution in ortho position and acidic residue group is discussed with respect to the bond length changes in the aromatic ring and aromaticity indexes. Energy differences between cis and trans conformations allow estimating the effect of intramolecular hydrogen bonds stabilizing the studied conformations. The trans conformation of parent formanilide is stabilized via the C(aromatic) -H∙∙∙O=C interaction with the energy of around 4 kJ・mol-1. The selected anilide series represent model compounds for drug design.
