Received: February 7th, 2021 ; Accepted: April 10th, 2021 ; Published: April 29th, 2021 ; Correspondence: [email protected] order to identify the most suitable varieties for organic farming, the Institute of
Agricultural Resources and Economics in 2018 started study four legume species. The
independent variables of the study were the legume genotypes: faba bean (Vicia faba L., cv.
‘Isabell’, ‘Lielplatone’, ‘Laura’, ‘Boxer’), field pea (Pisum sativum L, cv. ‘Astronaute’, ‘Bruno’,
‘Rebekka’, ‘Zaiga’), narrow lupine (Lupinus angustifolius L., cv. ‘Sonet’, ‘Probor’, ‘Derliai’,
‘Haags Blau’), and soya (Glycine max L., cv. ‘Annucha’, ‘Sculptor’, ‘Augusta’). The soil types
of the experimental organic field were sod–podzolic, sandy loam, and loamy sand. At the start of
the study the organic substance concentration was 15–18 mg kg-1
, pHKCl was 5.3–5.98, the
concentration of plant - available phosphorus (P205) was 133.2–182.9 mg kg-1
, and the
concentration of potassium (K2O) - 69.2–109.7 mg kg-1
. Green manure (buckwheat) was a
pre-crop, incorporated in autumn. For the comparison of economic indicators, the gross coverage
calculation was used, which based on the difference obtained by subtracting variable costs from
the valuation of gross output. All variable costs and revenues were included in the gross margin
calculation without value added tax. The study indicated large differences in yields between
genotypes. From the economic point of view, the most suitable cultivars for cultivation according
to the organic farming method were: field beans - ‘Isabell’ and ‘Lielplatone’ with average gross
cover (GC), 505.40 and 504.60 EUR, respectively, field peas - ‘Bruno’ (GC 379.60 EUR),
narrow-leaved lupin - ‘Derliai’ (GC 647.70 EUR), soybeans - ‘Sculptor’ (GC 204.40 EUR).
Among the legume species studied, lupine showed the highest economic performance, among the
genotypes - cultivar ‘Derliai’ (α = 0.05)

The Risk Assessment and Prediction Tool (RAPT) for Discharge Planning in a Posterior Lumbar Fusion Population
BACKGROUND: As the use of bundled care payment models has become widespread in neurosurgery, there is a distinct need for improved preoperative predictive tools to identify patients who will not benefit from prolonged hospitalization, thus facilitating earlier discharge to rehabilitation or nursing facilities.OBJECTIVE: To validate the use of Risk Assessment and Prediction Tool (RAPT) in patients undergoing posterior lumbar fusion for predicting discharge disposition.METHODS: Patients undergoing elective posterior lumbar fusion from June 2016 to February 2017 were prospectively enrolled. RAPT scores and discharge outcomes were recorded for patients aged 50 yr or more (n = 432). Logistic regression analysis was used to assess the ability of RAPT score to predict discharge disposition. Multivariate regression was performed in a backwards stepwise logistic fashion to create a binomial model.RESULTS: Escalating RAPT score predicts disposition to home (P \u3c .0001). Every unit increase in RAPT score increases the chance of home disposition by 55.8% and 38.6% than rehab and skilled nursing facility, respectively. Further, RAPT score was significant in predicting length of stay (P = .0239), total surgical cost (P = .0007), and 30-d readmission (P \u3c .0001). Amongst RAPT score subcomponents, walk, gait, and postoperative care availability were all predictive of disposition location (P \u3c .0001) for both models. In a generalized multiple logistic regression model, the 3 top predictive factors for disposition were the RAPT score, length of stay, and age (P \u3c .0001, P \u3c .0001 and P = .0001, respectively).CONCLUSION: Preoperative RAPT score is a highly predictive tool in lumbar fusion patients for discharge disposition
The Effect of a Food Addiction Explanation Model for Weight Control and Obesity on Weight Stigma
There is increasing scientific and public support for the notion that some foods may be addictive, and that poor weight control and obesity may, for some people, stem from having a food addiction. However, it remains unclear how a food addiction model (FAM) explanation for obesity and weight control will affect weight stigma. In two experiments (N = 530 and N = 690), we tested the effect of a food addiction explanation for obesity and weight control on weight stigma. In Experiment 1, participants who received a FAM explanation for weight control and obesity reported lower weight stigma scores (e.g., less dislike of 'fat people', and lower personal willpower blame) than those receiving an explanation emphasizing diet and exercise (F(4,525) = 7.675, p = 0.006; and F(4,525) = 5.393, p = 0.021, respectively). In Experiment 2, there was a significant group difference for the dislike of 'fat people' stigma measure (F(5,684) = 5.157, p = 0.006), but not for personal willpower weight stigma (F(5,684) = 0.217, p = 0.81). Participants receiving the diet and exercise explanation had greater dislike of 'fat people' than those in the FAM explanation and control group (p values 0.05). The FAM explanation for weight control and obesity did not increase weight stigma and resulted in lower stigma than the diet and exercise explanation that attributes obesity to personal control. The results highlight the importance of health messaging about the causes of obesity and the need for communications that do not exacerbate weight stigma
Daily Energy Intake from Meals and Afternoon Snacks: Findings from the Malaysian Adults Nutrition Survey(MANS)
Meal and snack patterns are associated with energy and nutrient intakes and
consequently health and nutritional status. The aim of this paper is to describe
the percentage of daily energy intake from meals and afternoon snack among
Malaysian adults. The study included a representative sample of adults aged 18-
59 years (n=7349) from a nationwide Food Consumption Survey conducted by
the Ministry of Health. Information on dietary intake was obtained using a one
day 24-hour diet recall (24-HDR). Dietary data on 6886 adults were analysed
using Nutritionist ProTM and statistical analysis was carried out using the SPSS
13.0. The median percentage of daily energy intake is reported only for adults
consuming meals and afternoon tea and by socio-demographic characteristics as
well as body mass index (BMI) status. More than 80% of Malaysian adults
consumed morning meals, lunch and dinner and 54% reported having afternoon
tea. The median percentage of energy intake from morning meals, lunch, dinner
and afternoon tea was 29.9%, 30.5%, 32.4% and 17%, respectively. There were
variations in the median percentage of energy from meals and snacks according
to the socio-demographic variables and BMI status. It is important to understand
the eating patterns of Malaysians as the information can assist in efforts to address
obesity and diet-related chronic diseases among adults
Energy and nutrient intakes: findings from the Malaysian Adult Nutrition Survey (MANS)
Nutrition surveys based on a representative sample of the Malaysian adult population have hitherto not been reported. In 2003, the Ministry of Health, Malaysia, conducted the Malaysian Adult Nutrition Survey (MANS), the first and largest nutrition survey in the country which aimed to provide detailed quantitative information on nutritional status, food and nutrient intakes, and physical activity pattern on a nationwide representative sample of adult subjects between the ages of 18 and 59 years. The survey covered four zones in Peninsular Malaysia (Central, Southern, Northern and East Coast), Sabah and Sarawak. This paper presents the mean and selected percentiles of energy and nutrient intake of 6886 subjects by selected demographic and socioeconomic characteristics. Energy contributions by macronutrients and dietary adequacy in relation to the Recommended Nutrient Intake for Malaysians are also described. Information on dietary intake was collected by trained nutritionists using a one day 24-hour diet recall. Dietary data were analysed using Nutritionist Pro, a diet analysis software and statistical analysis was carried out using the SPSS ver. 13.0. In most of the demographic and socioeconomic groups, males had higher mean energy (1776 kcal) and nutrient intake and percent achievement of RNI than females (1447 kcal). The proportions of calories derived from macronutrients were within the recommendations for a healthy diet. Intake of micronutrients such as iron, calcium and vitamin A was about 50% of RNI particularly in women. Sodium intake of Malaysians, not reported in earlier studies, is also made available. Under-reporting using the EI/BMR ratio was found in half of the population studied. The present study provides the first national estimates of energy and nutrient intake of the Malaysian adult population. Regular nutrition surveys are needed at the national level to provide valuable information on trends in food and nutrient intake, particularly among age and ethnically diverse subgroups of the population
A systematic literature review of skyline query processing over data stream
Recently, skyline query processing over data stream has gained a lot of attention especially from the database community owing to its own unique challenges. Skyline queries aims at pruning a search space of a potential large multi-dimensional set of objects by keeping only those objects that are not worse than any other. Although an abundance of skyline query processing techniques have been proposed, there is a lack of a Systematic Literature Review (SLR) on current research works pertinent to skyline query processing over data stream. In regard to this, this paper provides a comparative study on the state-of-the-art approaches over the period between 2000 and 2022 with the main aim to help readers understand the key issues which are essential to consider in relation to processing skyline queries over streaming data. Seven digital databases were reviewed in accordance with the Preferred Reporting Items for Systematic Reviews (PRISMA) procedures. After applying both the inclusion and exclusion criteria, 23 primary papers were further examined. The results show that the identified skyline approaches are driven by the need to expedite the skyline query processing mainly due to the fact that data streams are time varying (time sensitive), continuous, real time, volatile, and unrepeatable. Although, these skyline approaches are tailored made for data stream with a common aim, their solutions vary to suit with the various aspects being considered, which include the type of skyline query, type of streaming data, type of sliding window, query processing technique, indexing technique as well as the data stream environment employed. In this paper, a comprehensive taxonomy is developed along with the key aspects of each reported approach, while several open issues and challenges related to the topic being reviewed are highlighted as recommendation for future research direction
A practical and user-friendly toxicity classification system with microbiotests for natural waters and wastewaters
Various types of toxicity classification systems have been elaborated by scientists in different countries, with the aim of attributing a hazard score to polluted environments or toxic waste-waters or of ranking them in accordance with increasing levels of toxicity. All these systems are based on batteries of standard acute toxicity tests (several of them including chronic assays as well) and are therefore dependent on the culturing and maintenance of live stocks of test organisms. Most systems require performance of the bioassays; on dilution series of the original samples, for subsequent calculation of L(E C50 or threshold toxicity values. Given the complexity and costs of these toxicity measurements, they can only be applied in well-equipped and highly specialized laboratories, and none of the classification methods so far has found general acceptance at the international level. The development of microbiotests that are independent of continuous culturing of live organisms has stimulated international collaboration. Coordinated at Ghent University, Belgium, collaboration by research groups from 10 countries in central and eastern Europe resulted in an alternative toxicity classification system that was easier to apply and substantially more cost effective than any of the earlier methods. This new system was developed and applied in the framework of a cooperation agreement between the Flemish community in Belgium and central and eastern Europe. The toxicity classification system is based on a battery of (culture-independent) microbiotests and is particularly suited for routine monitoring. It indeed only requires testing on undiluted samples of natural waters or wastewaters discharged into the aquatic environment, except for wastewaters that demonstrate more than 50% effect. The scoring system ranks the waters or wastewaters in 5 classes of increasing hazard/toxicity, with calculation of a weight factor for the concerned hazard/toxicity class. The new classification system was applied during 2000 by the participating laboratories on samples of river water, groundwaters, drinking waters, mine waters, sediment pore waters, industrial effluents, soil leachates, and waste dump leachates and was found to be easy to apply and reliable. © 2003 Wiley Periodicals, Inc
