Concentrations of metallothionein in the bivalve molluscsAnodonta spp.andUnio spp.from Latvian lakes with different anthropogenic pressure

2013

Concentrations of metallothioneins (MT) were analysed in bivalve molluscs Anodonta spp. and Unio spp. from 6 lakes and watercourses of Latvia with different anthropogenic pressure. The aim of the study was to find the relationship between MT in molluscs and concentrations of heavy metals in sediments. Unio spp. and Anodonta spp. showed no significant differences in the concentrations of MT. High concentrations of heavy metals (Cd, Pb, Hg, Cu, Zn) were detected in the deepest parts of polluted water bodies, however their concentrations significantly decreased in near shore sediments inhabited by molluscs. Only Zn tends to accumulate in the molluscs, reaching 2-7 times higher concentrations i…

The developmental dynamics of task-avoidant behavior and math performance in kindergarten and elementary school

2012

Besides cognitive factors, children's learning at school may be influenced by more dynamic phenomena, such as motivation and achievement-related task-avoidant behavior. The present study examined the developmental dynamics of task-avoidant behavior and math performance from kindergarten to Grade 4. A total of 225 children were tested for their arithmetic skills in kindergarten and in Grades 1, 2, and 4 of elementary school. Children's task-avoidant behavior in learning situations was rated by their teachers. The results of latent growth curve analyses showed that math performance and task-avoidant behavior develop in tandem: an increase in task-avoidant behavior was related to less improvem…

Motywacja jako zmienna w badaniach pedagogicznych z odniesieniami do aktywności sportowej

2018

Celem artykułu jest zaprezentowanie roli motywacji w wychowaniu i w sporcie, w kontekście traktowania motywacji jako zmiennej zależnej bądź zmiennej niezależnej w badaniach edukacyjnych. Motywacja może mieć wpływ na osiąganie pożądanych wyników w nauce i w sporcie. Możliwa jest jednak także sytuacja odwrotna: lepsze wyniki i osiągnięcia mogą zwiększać poziom motywacji do podejmowania dalszych wysiłków. Artykuł składa się z trzech części. W pierwszej przywołane są najważniejsze koncepcje i stanowiska dotyczące motywacji, w drugiej opisane są różne sposoby traktowania motywacji jako zmiennej w badaniach. W trzeciej części – przy uwzględnieniu tych różnic – ukazane są możliwe konsekwencje i po…

‘So close, yet so different’ – reflections on the multicultural course of Slavic languages

2019

The complexity of language learning may be expanded to learning the languages belonging to the same language family, for example, Slavic languages. This paper reports on the reflection-on action research aimed at the increase of learners’ multicultural competence and enhancement of critical thinking at the interdisciplinary, blended course of Slavic languages and cultures. The course organized in modules is implemented in Moodle. Course content is designed by the teacher; however, Slavic languages are presented by native speakers of these languages. Learners have an opportunity to get familiar with Slavic languages, history, and culture from the presenters’ perspective, what generally resul…

MULTINATIONAL ENTERPRISES – DYNAMICS AND TRENDS

2012

Multinational enterprises (MNEs) represent both cause and result of the new economic geography of globalization. Thus, the dynamics and trends of the world’s most influential MNEs contribute decisively to the new global architecture and to the economic development, being influenced, at their turn, by these processes of continuous reconfiguration and evolution that take place on the global arena. The paper proposes a comparative (in space) and historical (in time) analysis of the most well known global rankings of the multinational enterprises – Fortune Global 500 on one hand, and The world's top 100 non-financial TNCs, ranked by foreign assets and Top 100 non-financial TNCs from developing …

The early changes in trunk muscle strength and disability following lumbar spine fusion

2012

To analyze trunk muscle function pre- and postoperatively in patients undergoing lumbar spine fusion. Associations between changes in trunk muscle strength and disability were also studied.A total of 114 patients undergoing lumbar spine fusion participated in the study. The flexion and extension strength of the trunk was measured preoperatively and 3 months after surgery using a strain-gauge dynamometer. Disability and pain during the past week was evaluated with the Oswestry disability index (ODI) and visual analog scale (VAS), respectively.Preoperative trunk extension and flexion strength levels were 319 N and 436 N in males, respectively, and 160 N and 214 N in females, respectively. In …

Treatment of Knee Osteoarthritis with Bone Marrow-Derived Mononuclear Cell Injection: 12-Month Follow-up.

2018

Objectives To evaluate the main symptoms of knee osteoarthritis (OA) and tissue structure changes after a single dose bone marrow–derived mononuclear cell (BM MNC) intra articular injection. Case series study. Patients with knee OA Kellgren Lawrence (K-L) grade II and III received 1 injection of BM MNC. The clinical results were analyzed with the Knee injury and Osteoarthritis Outcome Score (KOOS) and Knee Society Score (KSS) before, 3, 6, and 12 months after injection. Radiological evaluation was performed with a calibrated x-ray and the magnetic resonance (MR) imaging before and 6 to 7 months postinjection. Results A total of 34 knees were treated with BM MNC injections. Mean (±SD) age of…

Pain and clinical findings in the low back: a study of industrial employees with 5-, 10-, and 28-year follow-ups.

2009

Little is known about the relationships of clinical findings in the low back with low back pain (LBP) in the normal working population. We studied whether physiotherapist's findings in the low back were associated with local and radiating LBP among a cohort (n=902) of employees in the engineering industry. A systematic non-proportional sample was drawn in strata by age, gender, and occupational class. The non-proportionality aimed at increasing sample size in smaller strata. Physiotherapists performed the straight-leg raising test (SRL), and made assessments of the fingertip-to-floor distance and pain in palpation of the lumbar interspinous spaces. The variables on pain at the interspinous …

Estimation of structural and geometrical properties of cortical bone by computerized tomography in 78-year-old women

2009

The structural and geometrical properties of the tibia shaft were investigated at two sections by means of computerized tomography (CT) in 78-year-old women with high (n = 19) and low (n = 17) calcaneal bone mineral density (BMD, g/cm3) previously measured by 125I-photon absorption. The high BMD group had a 20-21% higher tibial BMD and 9-12% higher bone cross-sectional area than was observed in the low BMD group. The distribution of bone mass indicated that the low BMD group had lost bone mainly from the endosteal surface, especially in the anterior part of the tibia. However, both groups had a similar basic pattern of mass distribution at the measured sections. The high BMD group had highe…
