Title: Method for assessing progression of glomerulonephritis
Inventor: SEMYDOTSKA ZHANNA DMYTRIVNA
Filed: 2001-11-20
Abstract: The method for assessing progression of glomerulonephritis is based on assaying fibronectin in biological liquids samples. Additionally the content of endotelin-1 is assaying in blood samples. The chronic glomerulonephritis with sufficient renal function is suggested when fibronectin and endotelin-1 content amounts to 436.061±170,75 μg/ml and 51.115±14.041 pg/ml respectively. The chronic glomerulonephritis with chronic renal insufficiency stage I is suggested when fibronectin and endotelin-1 content amounts to 354.91±189.83 μg/ml and 58,304±9,859 pg/ml respectively. The chronic glomerulonephritis with chronic renal insufficiency stage II is suggested when fibronectin and endotelin-1 content amounts to 326,47±181,9 μg/ml and 57.425±6.803 pg/ml respectively. When fibronectin content equals to 287.43±114.84 μg/ml and endotelin-1 content amounts to 61.03±12.059 pg/ml the chronic glomerulonephritis with chronic renal insufficiency stage III is suggested.

Title: Wind-operated turbine (wind generator) with horizontally -and vertically-positioned folding blades
Inventor: PAPAGEORGIOU CHRYSOSTOMOS TAXIARCHI
IPC: F03B17/06
Filed: 2012-04-10
Abstract: The invention relates to a wind generator having two systems of horizontally- and vertically-positioned blades 2, the blades of the one system being positioned in the void space of the blades of the other. A wind indicator assists the closure of the blade while for its opening an auxiliary blade is utilised at the base of the main one. At the base of the shaft there are placed the braking system, the gear box, and the power generator set either directly on the shaft or under angle. The arrangement of the horizontally-positioned blades is similar to the arrangement of the vertically-positioned blades while a gears system is placed between the two systems for inciting the rotation of a vertical shaft. Two vertical beams retain the horizontal shaft in position and allow the 360 deg-rotation of the air turbine. The mechanism assisting the closure of the blades is placed at the two ends of the shaft. The wind indicator is exclusively used for assisting the direction of the wind generator into the wind. The remaining elements are similar to these of the vertical shaft.

Title: 위생양말
Filed: 1994-07-06
Abstract: 본 발명은 양말의 개선에 대해 개시한다. 
     일반적으로 양말은 발의 발부리에서 부터 다리부분까지 덮어 감싸주는 단순한 구성이므로 발가락 사이사이나 발가락 기부의 움푹들어간 부위의 땀을 제대로 흡수하지 못하여 악취가 발생하고 무좀등의 피부질환이 자주 걸리는 문제가 있다. 이에따라 종래에는 발가락을 각각 끼워 착용하는 "발가락 양말"이 개발되었으나, 발가락 사이에 흡수된 땀이 건조되지 못하여 무좀발생을 가증시켰으며, 무좀에 걸린 사용자가 착용하면 무좀부위에 도포된 약이나 진물에 의해 양말과 피부가 달라붙는 등 무좀을 더 악화시키는 결과를 초래하였다. 
     본 발명에서는 발부리부와 같이 무좀이 발생하기 쉬운 부위의 양말을 편물간극을 다른부위의 편물간극보다 크게 형성시켜 통풍구가 형성되도록 하여 공기가 원활하기 흐르도록 함으로써, 종래의 문제점들을 해결하였다.
