Dysmenorrhea is a painful condition that occurs during menstruation can interfere with activities and cause pain in the lower abdomen, which radiates to back legs. Handling of dysmenorrhea be done non-pharmacologically, one ginger water compress therapy. The purpose this study was determine effect compresses on reducing adolescents SMA Negeri 5 Makassar.

The cyclic performance of structural steels after exposure to various elevated temperatures and cooling-down methods was experimentally investigated in this paper. Four types frequently used were tested including Chinese mild steel Grade Q235, high-strength Q345, stainless S304 S316. A total eighty specimens prepared using three different heating–cooling processes before being subjected loads. ...

There is uncertainty about average and peak levels of radioactivity to which some people are being exposed. Radioactive materials cause harm only when not enough antioxidants are present to soak up the extra electrons (energetic free radicals; oxidative stressors) induced by radioactive particles. Radiation is like a submolecular fire. There is a temperature above which even the best fire resis...

Abstract Wood has the ability to absorb and desorb moisture, which can affect its dimensional size when in use. Limiting this provide products with greater shape stability less stresses on external coatings. One method that been investigated for achieving through chemical modification. In work, stabilisation imparted Scots pine sapwood by modification maleic anhydride (MA) combined sodium hypop...

The increasing world population boosted the demand for basic needs such as energy, water, and food. In turn, agricultural production has increased, generating a large amount of agro-industrial waste every year. Globally, Brazil is seventh-largest rice producer, State Rio Grande do Sul responsible 70% in Brazil. Rice husks are composed organic compounds (cellulose, hemicellulose, lignin, extract...

The procedure previously described (Zwarenstein, 1949) has been modified as follows. A small knife-point (about 5 mg.) of solid o-tolidine hydrochloride is added to 5 drops of urine in a test-tube and thoroughly mixed. A drop of the mixture is placed on a small piece of Whatman No. 1 filter paper (about 17 mm. square) on a white porcelain tile. The drop is allowed to soak into the paper and one...

Even after heat soaking, toughened glass is liable to a few apparently spontaneous failures, generally attributed to incomplete conversion of nickel sulphide inclusions. Another alternative is explored here: even with full conversion, inevitably some of these inclusions are too small to fail in the heat soak, but may cause failures at unexpectedly low loads in service. Taking this into account ...

Timber and timber products are renewable materials that, due to their durability strength properties, meet the requirements of construction industry, widely used in buildings. An analysis scientific literature has shown that there is a lack detailed research fully investigates influence rate increase moisture content on mechanical and, especially, properties LVL panels. Upon immersion into wate...
