Modelling the growth, development and yield of Triticum durum Desf under the changes of climatic conditions in north-eastern Europe.

How agricultural ecosystems adapt to climate change is one of the most important issues facing agronomists at the turn of the century. Understanding agricultural ecosystem responses requires assessing the relative shift in climatic constraints on crop production at regional scales such as the temperate zone. In this work we propose an approach to modeling the growth, development and yield of Triticum durum Desf.

Back pain in physically inactive students compared to physical education students with a high and average level of physical activity studying in Poland.

Background: The aim of the study was (1) to characterise back pain in physically inactive students as well as in trained (with a high level of physical activity) and untrained (with an average level of physical activity) physical education (PE) students and (2) to find out whether there exist differences regarding the declared incidence of back pain (within the last 12 months) between physically inactive students and PE students as well as between trained (with a high level of physical activity) and untrained (with an average level of physical activity) PE students.

Methods: The study included 1321 1st-, 2nd- and 3rd-year students (full-time bachelor degree course) of Physical Education, Physiotherapy, Pedagogy as well as Tourism and Recreation from 4 universities in Poland. A questionnaire prepared by the authors was applied as a research tool.

[Nutritional status of patients in hospitals in Poland. More thorough assessment of nutritional status of adult patients].

The purpose of the study was a more thorough assessment of the nutrition state of patients admitted to hospitals in Poland. The study was carried out in four hospitals at teaching centre level, in four hospitals at province level, and in four county hospitals. The patients for the study were selected randomly from 3310 adult patients (every 10th patient admitted to these hospitals).

[Nutritional status of patients in hospitals in Poland. I. Screening of adult patients].

The aim of the study was a screening assessment of the nutritional status of patients admitted to hospitals and discharged from hospitals. The study was carried out in 4 university hospitals, 4 woivodeship hospitals and 4 district hospitals. In randomly selected 3310 patients (every 10th patient admitted to hospital) anthropometric parameters were assessed: body height, body mass, body mass index (BMI), waist-hip ratio (WHR), arm circumference, blood morphological and biochemical parameters were determined (erythrocyte, white blood cell and lymphocyte count in blood, albumin and haemoglobin concentration in serum).
