Objectives: To describe the relationship between sensorimotor function and walking in incomplete SCI. Methods: 25 subjects were assessed using Lower Extremity Motor (LEMS) and Pinprick (LEPS) scores, and 7 walking measures: FIM-Locomotor Score, Assistive Device Score, Walking Index for SCI, 10-metre Walk Test (10mWT), Timed Up and Go (TUG), Six-Minute Walk Test (6MWT) and Walking Mobility Scale. Results: Walking and sensorimotor function varied between subjects. Walking measures significantly correlated with LEMS and individual leg muscles but not LEPS. 21/22 ambulatory subjects had LEMS threshold>20. Non-ambulatory subjects didn’t achieve threshold. Not all subjects completed all walking measures: 10mWT: n=19; TUG: n=14, 6MWT: n=13. Most walking measures were significantly related. 10mWT and 6MWT were highly correlated. Subjects walking0.95 m/s didn’t reach predicted 6MWT. Conclusion: Lower extremity strength is important for walking and should be further examined with other factors in a range of subjects across different measures to fully understand these relationships.

Early strength increase with training is normally attributed to neural adaptations but recent evidence suggests that muscle hypertrophy occurs earlier than previously thought. The purpose of this study was to examine the time course of adaptation through 20 days of training and 5 days of detraining. Twenty-two untrained subjects trained one arm every 2nd day for 20 days. Subjects performed isokinetic eccentric biceps training at 90°/s (6 sets of 8 reps). Muscle thickness (reported in cm) via ultrasound, strength (reported in Nm) and muscle activation (electromyography) were measured before, during and after training (9 time points). Muscle thickness increased after 8 days of training (3.66±0.11 to 3.90±0.12; p<0.05) and remained above baseline until the end of training (3.97±0.12). After 5 days of detraining muscle thickness decreased (3.97±0.12 vs. 3.85±0.11; p<0.05), but remained higher than baseline (p<0.05). Muscle thickness did not change significantly in the untrained arm at any time point. Strength in the trained arm decreased after 8 days of training (65.6±4.1 to 57.5±3.5; p<0.05) and remained suppressed throughout the study. Muscle activation amplitude increased after 14 days of training (p<0.05) and remained elevated throughout the study. In conclusion, biceps muscle thickness increases very rapidly with frequent intense eccentric training although this type of training appears to impair strength. These findings provide additional evidence that muscle hypertrophy may occur much faster than has been generally accepted.

Psykosocial motståndskraft (”resilience”) innebär att klara sig bra i samband med motgång. Det är viktigt att främja detta i unga år då utvecklingskaskader (kedjereaktioner) som följd av olika upplevelser kan påverka resten av livet. Syftet med denna studie var att undersöka hur motståndskraft uppfattas och hur det främjas i det dagliga arbetet i förskolan. Sju intervjuer med förskolepersonal genomfördes och analyserades och resultatet tyder på att begreppet i sig inte är känt men att många delar av det appliceras. Resultatet visade att personalen uppfattar att motståndskraft berör barnets inre förmågor, faktorer i interaktion med omgivningen och förskolans specifika roll. Barnets inre förmågor kan sammanfattas i temat inre motivation, interaktionen med omgivningen i temat anknytning och förskolans speciella roll som temat ekologiskt system. Framtida forskning kan utökas med hjälp av resultatet, förskolor kan använda redovisade faktorer för mer strukturerat hälsoförebyggande arbete och hälsobetydelsen av små barngrupper får ytterligare stöd för beslutsfattare.

Recycling has proven not only to address today’s economical, environmental and social issues, but also to be imperative for the sustainability of human technology. The current thesis has investigated the feasibility of a new philosophy for Recycling (Alloying-Recycling) using steel 1020 and aluminum 6061T6. The study was limited to the metallurgical aspects only and has highlighted the potential of recycled alloys made of recycled aluminum and steel to exhibit substantially increased wear resistance and strength-to-weight ratio as compared to initial primary materials. Three alloy-mixtures are considered: TN3 (5wt% 1020 +95wt% 6061T6); TN5 (0.7wt% 1020 + 99.3wt% 6061T6); and TN4 (10wt% 6061T6 + 90wt% 1020). A Tucker induction power supply system (3kW; 135-400 kHz) is used to melt the alloy mixtures for casting in graphite crucibles. Heat treatment of the cast samples is done using a radiation box furnace. Microscopy, Vickers hardness and pin-on-disc abrasive wear tests are performed. Casting destroyed the initial microstructures of the alloys leading to a hardness reduction in the as-cast and solution heat-treated aluminum rich samples to 60 Hv from 140 Hv. Ageing slightly increased the hardness of the cast samples and provided a wear resistance two times higher than that of the initial 6061T6 material. On the steel rich side, the hardness of the as-cast TN4 was 480 Hv, which is more than twice as high as the initial hardness of steel 1020 of 202 Hv; this hints to strong internal and residual stress, probably martensite formation during fast cooling following casting. Solution heat treatment lowered the hardness to the original value of steel 1020, but provided about ten (10) times higher wear resistance; this suggests higher ductility and toughness of normalised TN4 as compared to 1020. In addition, TN4 exhibits about 25% weight reduction as compared to 1020. The actual recycling process and the effect of non-metallic impurities shall be investigated in future works. Also, the casting and heat treatment processes need to be improved.

Strength for African American women and its psychological ramifications are being newly conceptualized and explored empirically in psychological research. The Strong Black Woman Attitudes Scale, (Thompson, 2003) was created to empirically test a three factor theoretical model: self reliance, affect regulation, and caretaking as a reliable culturally relevant coping mechanism for African American women. The primary aim of this study is to explore if cultural coping (SBW) moderates the relationship between depression and suicide in African American women. Other aims include, replicating the factor structure of the SBWAS with a community sample, and examining relationships between the SBW, racial identity, traditional coping, and depression. The Strong Black Woman Attitude Scale (SBWAS) was used to measure cultural coping, and the Ways of Coping Questionnaire (WOCQ) was used to measure traditional coping. Racial regard and centrality subscales from the Multidimensional Inventory of Black Identity (MIBI) measured racial identity and the Beck Depression Inventory (BDI) and Beck Suicide Scale (BSS) measured depression and suicide respectively. Results showed significant moderations for the total SBW score and the affect regulation subscale. Additionally, racial identity was positively associated with cultural coping, and cultural coping was negatively associated with traditional coping. Depression was positively related to the SBW and suicide. The three factor model was also upheld. The results of this study support the notion that strength for African American women can have detrimental psychological effects on women utilizing this coping style.
