This study aims to determine the ethnomathematics in process of making Kedang woven fabrics. The approach used is qualitative ethnographic research. subjects this consisted two weavers. data collection observation, interview, and documentation techniques. Data were analyzed descriptively qualitatively. results showed that there are mathematical concepts can be observed fabrics, namely integers,...
Accumulation of Aluminium (Al) at concentrations far above 1,000 mg kg-1 in aboveground plant tissues of Arbor aluminosa (Symplocos) species is the main reason why traditional Indonesian weavers rely on their leaves and bark as a mordant for dyeing textile. Recently, Symplocos species have become a flagship species for the conservation efforts of weaving communities due to their traditionally n...
INTRODUCTION Several species of granivorous birds are responsible for damage to cereal crops in Senegal. Palearctic migrants, such as ruffs (Philomachus pugnax), godwits (Limosa limosa), and waterfowl damage newly sown rice seed or germinating plants. The main pests to ripening cereals are the red-billed quelea (Quelea quelea), black-headed weavers (Ploceus melanocephalus), village weavers (P. ...
Recent research has shown that nectar properties of flowers pollinated by generalist avian nectarivores differ markedly from those of flowers pollinated by specialist avian nectarivores. In particular, flowers pollinated by generalist avian nectarivores tend to have very dilute nectar dominated by hexose sugars. To establish whether pollinator-mediated selection can explain these traits, we tes...
The midbrain of the adult homozygous weaver (wv/wv) mouse is notable for a reduction in the numbers of dopamine-containing cells in the substantia nigra (A9) and the retrorubral nucleus (A8). We have determined that the reduction in tyrosine hydroxylase (TH)-positive neurons in the ventral midbrain of the weaver is attributable to the loss of neurons after postnatal day 7 (P7). Because the numb...
We estimated survival and movement probabilities in relation to breeding-colony size in the sociable weaver (Philetairus socius) by using multistate statistical methods, in which survival and movement to time t þ 1 is conditional on an individual’s colony size at time t. The sociable weaver is a colonial, cooperatively breeding species that builds a massive communal nest, with colony size rangi...
BACKGROUND/OBJECTIVE Textile manufacturing is a complex industry that has frequently been associated with bladder cancer. However, results have not been consistent. This study investigated the risk of bladder cancer in Spanish textile workers. METHODS We analysed data from a multicentre hospital-based case-control study carried out in Spain (1998-2001) including 1219 cases of bladder cancer a...
