AbstractThe goal of this study was to assess the water needs of elderberry. The investigation included elderberry plants that had been planted in land reclamation areas more than three years earlier. The water needs were evaluated for 5 agro-climatic regions of Poland. The calculations were based on the observation of meteorological conditions in the years 1981-2010 for the period from June 1 to July 31. To determine the water needs, the plant coefficient method was applied. The Blaney-Criddle formula, which was modified for Polish conditions by Żakowicz (2010), was used to calculate the reference evapotranspiration. The plant coefficients of elderberry, adapted to the reference evapotranspiration, were adjusted to Żakowicz’s method. The rainfall deficit with the probability of occurrence: N50%, N25% and N10%, was assessed in accordance with Ostromęcki’s method. The highest water needs of elderberry occurred in central-north-west (264 mm) and central-east (262 mm) Poland, while the lowest (244 mm) in the south-east region. In June, the highest total monthly water needs (119 mm) were noted for south-west Poland, whereas the lowest (107 mm) for the south-east region. In June and July, except for the central-north-west region, an upward time trend of water needs was noted throughout Poland. In June and July, the highest value (135 mm) of rainfall deficit N50% and N25% was estimated for the central-north-west region, while the highest rainfall deficit N10% (269 mm) for central-east Poland. The results of the presented research find application in the planning of irrigation treatments for elderberry in Poland.

Essential oils serve as a natural alternative to chemical or synthetic antimicrobials and antioxidants to fight against food borne pathogens or spoilage organisms, inhibiting lipid peroxidation and extending the shelf life of fish and other seafood. This study examines the antibacterial properties of essential oils from leaves of Ocimum gratissimum L. from two localities of the North West and South West of Cameroon on some pathogenic spoilage gram negative and positive bacteria isolated from mackerel, and their antimicrobial and antioxidant effectiveness on the fish quality during preservation for one month at -18oC. The plant materials were harvested from Bambili, the North West Region of Cameroon and from Mbonge, the South West Region of Cameroon and the essential oils extracted by hydro-distillation using Clevenger-type apparatus. Escherichia coli, Salmonella typhi and Staphylococcus aereus were isolated from mackerel by culture techniques and their susceptibility to the essential oils determined by well diffusion method. Psychrophilic bacteria and Enterobacteraceae counts were used to evaluate the microbiological quality of the fish during storage. Total volatile basic nitrogen and thiobarbituric acid reactive substance assays were used as indices to assess the biochemical quality of the fish during storage. Antibacterial susceptibility test showed that essential oils of O. gratissimum from the North West and South West Regions were active on all the tested microorganisms with different degree.The inhibitory diameters for essential oil from the South West Region were 28.0 mm, 27.2 mm and 26.0 mm while that for essential oil from the Bambili were 24.1 mm, 20.4mm and 21.9 mm for Staphylococcus aereus, Escherichia coli and Salmonella typhi respectively. At the end of storage periods, the values of Psychrotrophs plate counts, total volatile base nitrogen and thiobarbituric acid reactive substances for fish samples treated with essential oil from the Mbonge were 2.71log10cfu/g, 12.88 mgN/100g and 0.88 mgMDA/Kg, while that treated with North West essential oil were 3.00 log10cfu/g, 16.24 mgN/100g and 1.26 mgMDA/Kg respectively. From the obtained results, essential oil of O. gratissimum from the Mbonge was the most effective in preserving Atlantic mackerel.

AbstractSome dietary patterns (DPs) identified across the world are classified as universal (e.g. ‘Western’ or ‘Prudent’) while other patterns are country-specific, often labelled as ‘Traditional’. Regional, country-level variations in DPs adherence were not extensively studied to date. The aim of this study was to analyse differences in DPs adherence among Polish females between country regions. A cross-sectional study was performed using data from a representative sample (n = 1107) of Polish females 13–21-year-old, enrolled for the Girls Eating Behaviours and Health Study. Initially, 2104 females were randomly selected from the Universal Electronic System of Population Register database. The response rate was 52.6%. All data were adjusted for survey weights to maintain the representativeness. Three short form food frequency questionnaires were applied. Four DPs were identified by principal component analysis: ‘Traditional Polish’ (positively loaded by higher consumption frequency of white bread, potatoes, meat and fat), ‘Vegetables and fruit’, ‘Fast-food and sweets’ and ‘Dairy and fats’. In line with the Polish database of Central Statistical Office, six Polish regions were considered: East (with the lowest Gross Domestic Product, GDP = 69.7; Poland = 100), North (DP = 84.8), North-West (GDP = 95.1), South (GDP = 98.8), South-West (GDP = 104.8) and Central (the highest GDP = 140.4). Multiple logistic regression analysis was used. Odds ratios (ORs) were adjusted for age and body mass index. Higher adherence to ‘Traditional Polish’ DP was found in 4 out of 5 regions (OR 2.02 to 2.53) when compared to the East region. Higher adherence to ‘Vegetables and fruit’ DP was found in 2 out of 5 regions (the South and the South-West; OR 1.71 and 1.81, respectively), when compared to the East region, and in 3 out of 5 regions (the South, the South-West and the Central; OR 1.69 to 2.23), when compared to the North-West region. Higher adherence to ‘Fast-food and sweets’ DP was found in the North region when compared to the three other regions as reference: the East (OR 1.94), the North-West (OR 1.93), and the South (OR 2.10). In young Polish females, high adherence to the ‘Traditional Polish’ DP was observed across the country, except of the poorest region (the East). The study highlights that young females from economically deprived regions are at higher risk of unhealthy (westernized) dietary behaviors while those living in more affluent regions more frequently consume fruit and vegetables being a high-cost food. Increasing the affordability of healthy foods should be considered as an important component of public health interventions, particularly in more deprived regions.

Abstract The aim of the study was to determine the prevalence of Mycoplasma bovis infection in clinical cases of bovine respiratory disease (BRD) in 2011. There were examined 841 serum samples and 41 nasal swabs and lungs of cattle from different farms of six regions of Poland (13 provinces). The obtained results indicated that the mean prevalence of M. bovis infection in Polish cattle population suffering from BRD was 64.3% and among them 8.4% of the animals were highly positive. On the other hand, in particular regions, it altered - 72.0% in east region, 52.7% in central region, 66.4% in south region, 64.1% in north-west region, 56.5% in north region, and 58.8% in south-west region. It should be added that within the presented regions, the highest values (82.4%) were reported in south region (Malopolskie province), whereas the lowest ones (42.9%) were in east region (Lubelskie province). However, field strains of M. bovis were isolated from the lungs of affected cattle only in the north-west region of Poland (Zachodniopomorskie province).

In modern Icelandic, spoken in the South, West, and North-West of Iceland, there is a phonemic opposition between voiced and voiceless nasals before stop consonants. For the present investigation the research instrument was the velograph. The purpose of the research was to investigate patterns of velar movement associated with each type of nasal consonants. The results show different types of velar movement organized according to two separate temporal patterns. For the voiceless nasals the movement of the velum is more rapid and begins earlier than for the voiced nasals. There are also significant differences in the nasalization of the preceding vowel according to whether the following nasal consonant is voiced or voiceless.

The Cyclopean Terrace Building lies to the north-west of the Lion Gate on the northern end of the Panagia Ridge and faces almost due west across the valley of the Kephissos and modern main road from Corinth to Argos. It lies just below the 200 m. contour line, and one terrace below the houses excavated in 1950–51 by Dr. Papadimitriou and Mr. Petsas to the east at the same end of the ridge. The area contains a complex of buildings, both successive and contemporary, and in view of the discovery of structures both to the south-west and, by the Greek Archaeological Service, to the north-east it is likely that this whole slope was covered by a portion of the outer town of Mycenae. This report will deal only with the structure to which the name Cyclopean Terrace Building was originally given, the so-called ‘North Megaron’, supported by the heavy main terrace wall.The excavation of this structure was begun in 1923. The main terrace wall was cleared and two L.H. IIIC burials discovered in the top of the fill in the south room. In 1950 it was decided to attempt to clear this building entirely in an endeavour to find out its date and purpose. The clearing was not, however, substantially completed until the close of the 1953 excavation season, and this report presents the available evidence for the date as determined by the pottery found beneath the building; the purpose is still a matter for study, though various tentative conclusions can be put forward.

Abstract Introduction: Modern Postnatal Care Services (PNC) in Nigeria is vital tool for providing quality health for mothers and newborns. Nonetheless, many regions in Nigeria are still struggling to achieve optimum utilisation of modern PNC services due to variation in associated socioeconomic factors of mothers based on their regions. This study aims at assessing regional socioeconomic factors associated with PNC services utilisation and its relationship with child morbidity in Nigeria. Methods Data for this study was extracted from the Nigeria Demographic and Health Survey (NDHS) 2018 birth recoded file dataset, with a sample size of 30713 women (aged 15–49). Data were analysed using descriptive statistics, Chi-Square Test and logistic regression. The main predictor variable was the region, while others included the type of PNC service utilised and various demographic variables of the respondents – age, education, type of residence, religion, ethnicity among others. Results The average age of the respondents was 29.5 ± 6.8. The use of modern PNC services ranged from South-West (20.3%), South-South (10.9%), South-East (23.0%), North-Central (22.0%), North-East (13.0%) to North-West (10.9%). The prevalence of child morbidity ranged from South-West (8.5%), South-South (9.8%), South-East (11.4%), North-Central (15.3%), North-East (26.3%) to North-West (28.7%). Child morbidity is significantly higher in the South-South (OR = 1.46), South-East (OR = 1.50), North-Central (OR = 1.13), North-East (OR = 2.31) and North-West (OR = 1.35) compared to the South-West. Conclusion Majority of women in Nigeria are not using modern PNC services. Regional variations in the use of PNC services and socio-demographic characteristics of mothers influence child morbidity in Nigeria. There is need for regional-specific context sensitisation for mothers in the use of modern PNC services.

The paper concentrates on the measurement of the total factor productivity of dairy farms in the south-west region of Bangladesh. The study used stochastic frontier approach for analyzing the technical efficiency of the dairy farms. Here, seventy dairy farms are considered as a sample. The data reveals that the number of labor and the quantity of food are statistically significant at a 1 percent level of significance.The data also manifests that numerous farm-specific characteristics, i.e. farm size, farmer’s age, and amount of credit are statistically significant at 1 percent, 10 percent, and 10 percent respectively. The range of technical efficiency for the farms varies from 26 percent (minimum) to 95 percent (maximum) where the mean value is 68 percent for the dairy farms of the south-west region. This implies that an average output of milk production falls 32 percent short of maximum possible level. Hence, there is scope of improvement in this sector. Therefore, to improve the farm productivity government should provide proper training, and medical treatment facilities for the farms so that the animals become healthy. If it is possible to do so then the farm level production frontier will shift upward.
