PENGARUH MODEL SNOWBALL THROWING TERHADAP HASIL BELAJAR SISWA KELAS V PADA MATA PELAJARAN PKn DI SD INPRES XX SOLOT
2020
ABSTRACTThis study aims to determine student learning outcomes by using the snowball throwing modelon PKn subjects in the diversity of ethnic groups in Indonesia towards the learning outcomes ofstudents in class V SD Inpres XX Solot Nita District, Sikka Regency. This research is aquantitative study with the tipe of experimental research method used in this study using thepre-experimental (nondesings) type one-group pretest-design method. The population andresearch sample were all students of class V which numbered 14 students. The test instrumentused to determine is in the form of a pre-test and post-test. Based on the learning outcomes thevalues obtained the average experimental class in t…
150 years of rowing faster: what are the sources of more and more speed?
2015
Rowing has a 150 yr+ competitive history. Examining results from historic races like Oxford-Cambridge (established 1829) and the world championships (established 1893) reveals a linear increase in boat speed by 2-3% per decade. Boat velocity increases if propulsive power is increased and/or power losses are reduced. Over time, the propulsive power capacity of elite rowers has increased. Part of this increase is a result of recruiting athletes from a population that has become taller (1-3 cm per decade) and heavier. Modern world class rowers are typically 190-200 cm tall and weigh 90-100 kg. However, physical capacity does not scale directly with body dimensions but conforms instead to biolo…
Selection of low investment in sex in a cyclically parthenogenetic rotifer
2009
Cyclical parthenogens, which combine asexual and sexual reproduction, are good models for research into the ecological and population processes affecting the evolutionary maintenance of sex. Sex in cyclically parthenogenetic rotifers is necessary for diapausing egg production, which is essential to survive adverse conditions between planktonic growing seasons. However, within a planktonic season sexual reproduction prevents clonal proliferation. Hence, clones with a low propensity for sex should be selected, becoming dominant in the population as the growing season progresses. In this context, we studied the dynamics of the heritable variation in propensity for sexual reproduction among clo…
The Experience of Living through the Transition from Adolescence to Adulthood for Young People with Cerebral Palsy
2023
This study explored the lived experience of transition from adolescence to adulthood for young people with cerebral palsy to inform occupational therapy practitioners as to what might promote positive life opportunities. A phenomenological methodology was used with six participants, aged 18 to 25 years with cerebral palsy. The findings are presented in the form of hermeneutic stories and three themes: The storm of uncertainty; time, space and the body, Capsizing in a world of others and, Securing anchorage; being heard and understood. Recommendations include service integration across health, social care and education based on partnership and provision of coordinators. peerReviewed
PLASMA MEMBRANE REDOX SYSTEM IN THE ERYTHROCYTES OF ROWERS: PILOT STUDY
2015
Background: The oxidative stress results from a change in the physiological balance between oxidant and antioxidant species. The purpose of this study is twofold: first, to investigate the effects of long-term training in sports with high energy requirements on the redox balance which exists between the plasma vs. the erythrocytes; second, to study the activity of the PMRS (Plasma Membrane Redox System), which is a compensatory mechanism of cellular redox homeostasis, in the rowers’ erythrocytes in order to determine the rowers’ counteraction to oxidative stress. Methods: Venous blood samples was collected from rowers and control group; then FRAP (Ferric Reducing Activity Power) method has …
INTERFERENCE PHENOMENA IN FOREIGN LANGUAGE LEARNING- SOME OBSERVATIONS FROM ROMANIAN-ENGLISH CONTACT
2012
Foreign language learning is the locus of varying degrees of interference from the learner’s first language (L1), the product of this influence being called interlanguage. As such, it is important to identify those areas of the L1 which could lead to negative transfers into the target language and thus result in imperfect learning. The present paper is concerned with English learning by speakers of Romanian, and analyses possible L1 retentions resulting from the use of English borrowings that diverge grammatically from their original counterparts. The particular cases described will be those of borrowed words which have undergone a process of conversion, and the use of bilingual verb phrase…
Nitrogen uptake and nitrogen fertilizer recovery in old and modern wheat genotypes grown in the presence or absence of interspecific competition
2015
Choosing genotypes with a high capacity for taking up nitrogen (N) from the soil and the ability to efficiently compete with weeds for this nutrient is essential to increasing the sustainability of cropping systems that are less dependent on auxiliary inputs. This research aimed to verify whether differences exist in N uptake and N fertilizer recovery capacity among wheat genotypes and, if so, whether these differences are related to a different competitive ability against weeds of wheat genotypes. To this end, 12 genotypes, varying widely in morphological traits and year of release, were grown in the presence or absence of interspecific competition (using Avena sativa L. as a surrogate wee…
A fully automatic method for biological target volume segmentation of brain metastases
2016
Leksell Gamma Knife is a mini-invasive technique to obtain a complete destruction of cerebral lesions delivering a single high dose radiation beam. Positron Emission Tomography (PET) imaging is increasingly utilized for radiation treatment planning. Nevertheless, lesion volume delineation in PET datasets is challenging because of the low spatial resolution and high noise level of PET images. Nowadays, the biological target volume (BTV) is manually contoured on PET studies. This procedure is time expensive and operator-dependent. In this article, a fully automatic algorithm for the BTV delineation based on random walks (RW) on graphs is proposed. The results are compared with the outcomes of…
Labor Market Search, Housing Prices and Borrowing Constraints.
2010
Mortgage market deregulation in the early 1980s coincided in time with a sharp break in the cyclical behavior of many variables related to housing and to the labor market. This paper analyses the joint dynamics of labor market variables, output and housing prices in a search model with efficient bargaining and financial frictions. In a setting of household heterogeneity, only mortgaged-backed loans are available for impatient households, whose borrowing cannot exceed a proportion of the expected value of their real estate holdings. This feature of the credit market, together with search and matching frictions in the labor market, establish a strong link between credit constraints and consum…
"Awake Surgery" of Slow-Growing Tumors and Cortical Excitability Measured by EEG Recordings. Preliminary Results
2012
International audience; To investigate interhemispheric imbalance following "awake surgeries" of slow-growing tumors we recorded EEG in a visuo-manual RT paradigm. Increase of cortical excitability within the ipsilesional hemisphere was signed by increased ERPs amplitude for two patients. The cortical excitability in the lesioned hemisphere may be increased to maintain performances and cerebral plasticity.
