Abstract

In this work, carbon steel (CS) covered with bronze coating was treated by silane coupling agents with an aim to improve surface adhesion between metal and rubber blend. As we know the silane coupling agents offer the ability to form a durable bond between organic and inorganic materials. Through hydrolysis reaction R- silyl group can form a chemical bond with the inorganic surface. Two different chemical properties of materials provide high adhesive strength or improvement of the adhesion strength 1,2. The surfaces characteristics were analyzed by XPS, FTIR, and Contact angle measurements. Surface morphology of bronze surface treated by APS was investigated by AFM., In this work, carbon steel (CS) covered with bronze coating was treated by silane coupling agents with an aim to improve surface adhesion between metal and rubber blend.

Abstract

Pairs of peptide amphiphiles with immiscible hydrophobic tails were synthesized and their assembly formation was investigated. These pairs formed self-sorting supramolecular fibres using a standard heating-cooling protocol, while one pair with longer hydrophobic tails formed a co-assembly when an additional heating process was applied.

Abstract

A survey of nutrient and food oral intake was undertaken to clarify problems in nourishment support of chemotherapy outpatients with cancer diseases. The ingestion frequency survey (Food Frequency Questionnaire Based on Food Groups: FFQg) of nutrient and food intake was carried out in 54 patients, after chemotherapy at an outpatient clinic in Hyogo Prefectural Nishinomiya Hospital during three weeks from June 25,2007 to July 13,2007. Among them, 50 patients (92.6%) reported a valid response (14 breast, 13 colon, 6 stomach, 9 pancreas, and 8 other cancers). Body mass index (BMI; kg/m2, mean +/-SD) grouped by the type of the cancer was 22.3+/-3.1 in breast, 21.3+/-2.6 in colon, 17.9+/-2.0 stomach, 18.0+/-1.2 in pancreas and 22.6+/-1.8 in other cancers. BMIs in stomach or pancreas cancer patients were significantly low compared to those in patients with breast, colon, or other cancers. Each group's caloric intake per standard weight (kcal: mean+/-SD) was 31.4+/-5.3 in breast, 27.7+/-5.6 in colon, 34.2+/-10.3 in stomach, 29.1+/-5.0 in pancreas, and 26.8+/-6.4 in other cancers. No significant differences were recognized among them. In conclusion, oral intake in chemotherapy outpatients was secured from the result for each type of cancer; however, BMI was low in outpatients with stomach or pancreas cancer in spite of ingestion of food enough to maintain standard weight.
