background: toxoplasmosis is a parasitic disease caused by protozoan, toxoplasma gondii. infections of human are common and are usually asymptomatic. the infection may be serious if is transmitted to the fetus during pregnancy. prophylactic measures, early detection of the infection and treatment can avoid congenital toxoplasmosis and many long term effects. objective: seroepidemiological study...

Kualitas dari daya listrik pada sebuah motor induksi sangatlah penting, dikarenakan jika listriknya rendah akan berpengaruh turunnya efisiensi kinerja induksi. Untuk itu diperlukan suatu metode sehingga dapat dipertahankan. Pada penelitian ini dilakukan pemasangan variasi kapasitas kapasitor untuk mengetahui pengaruhnya kualitas tiga fasa tak berbeban. Kapasitas yang digunakan yaitu 9 µF , 16,5...

no unique method has been so far specified for determining the number of neurons in hidden layers of multi-layer perceptron (mlp) neural networks used for prediction. the present research is intended to optimize the number of neurons using two meta-heuristic procedures namely genetic and hill climbing algorithms. the data used in the present research for prediction are consumption data of water...

Fatty acid signature analysis (FASA) is a powerful ecological tool that uses essential fatty acids (FA) from the tissues of animals to indicate aspects of diet. However, the presence of vertical stratification in FA distribution throughout blubber complicates the application of FASA to marine mammals. Blubber biopsy samples were collected from adult female southern elephant seals (Mirounga leon...
