Hydroxyapatite bioceramics has attracted many material scientists as it is the main constituent of the bone and the teeth in human body. The synthesis of the bioceramics has been performed for years. Nowadays, the synthetic work is not only focused on the hydroapatite but also on the fluorapatite and chlorapatite bioceramics since later materials have also biological compatibility with human tissues; and they may also be very promising for clinic purpose. However, in comparison of the synthetic bioceramics with natural one on microstructure, a great differences were observed according to our previous results. We have investigated these differences further in this work since they are very important to appraise the synthetic bioceramics for their clinic application.The synthetic hydroxyapatite and chlorapatite were prepared according to A. Krajewski and A. Ravaglioli and their recent work. The briquettes from different hydroxyapatite or chlorapatite powders were fired in a laboratory furnace at the temperature of 900-1300°C. The samples of human enamel selected for the comparison with synthetic bioceramics were from Chinese adult teeth.

This is a combined study of two diffirent branches, photogrammetry and morphology of blood cells. The three dimensional quantitative analysis of erythrocytes using SEMP technique, electron computation technique and photogrammetry theory has made it possible to push the study of mophology of blood cells from LM, TEM, SEM to a higher stage, that of SEM P. A new path has been broken for deeply study of morphology of blood cells.In medical view, the abnormality of the quality and quantity of erythrocytes is one of the important changes of blood disease. It shows the abnormal blood—making function of the human body. Therefore, the study of the change of shape on erythrocytes is the indispensable and important basis of reference in the clinical diagnosis and research of blood disease.The erythrocytes of one normal person, three PNH Patients and one AA patient were used in this experiment. This research determines the following items: Height;Length of two axes (long and short), ratio; Crevice in depth and width of cell membrane; Circumference of erythrocytes; Isoline map of erythrocytes; Section map of erythrocytes.

Summary: My comment is basically restricted to the situation in which less-able students find themselves and refers only to literature in German. From this point of view I am basically able to confirm Marsh's results. It must, however, be said that with less-able pupils the opposite effect can be found: Levels of self-esteem in these pupils are raised, at least temporarily, by separate instruction, academic performance however drops; combined instruction, on the other hand, leads to improved academic performance, while levels of self-esteem drop. Apparently, the positive self-image of less-able pupils who receive separate instruction does not bring about the potential enhancement of academic performance one might expect from high-ability pupils receiving separate instruction. To resolve the dilemma, it is proposed that individual progress in learning be accentuated, and that comparisons with others be dispensed with. This fosters a self-image that can in equal measure be realistic and optimistic.

Abstract. Background: Suicide rates in older men are higher than in the general population, yet their utilization of mental health services is lower. Aims: This study aimed to describe: (a) what primary care providers (PCPs) can do to prevent late-life suicide, and (b) older men's attitudes toward discussing suicide with a PCP. Method: Thematic analysis of interviews focused on depression and suicide with 77 depressed, low-socioeconomic status, older men of Mexican origin, or US-born non-Hispanic whites recruited from primary care. Results: Several themes inhibiting suicide emerged: it is a problematic solution, due to religious prohibition, conflicts with self-image, the impact on others; and, lack of means/capacity. Three approaches to preventing suicide emerged: talking with them about depression, talking about the impact of their suicide on others, and encouraging them to be active. The vast majority, 98%, were open to such conversations. An unexpected theme spontaneously arose: "What prevents men from acting on suicidal thoughts?" Conclusion: Suicide is rarely discussed in primary care encounters in the context of depression treatment. Our study suggests that older men are likely to be open to discussing suicide with their PCP. We have identified several pragmatic approaches to assist clinicians in reducing older men's distress and preventing suicide.
