Abstract: Hemoglobin (Hb) is a parameter used to determine anemia prevalence. The average level of normal Hb at the end of pregnancy is around 12.5 g/dL, meanwhile, aproximately 5% of pregnant women have Hb level less than 11.0 g/dL. To date, Hb level below 11.0 g/dL especially at the end of pregnancy should be considered as an abnormal phenomenon and is usually caused by iron deficiency and not by hypervolemia which is commonly found in pregnancy. This study was aimed to determine the hemoglobin level of third semester pregnant women in Robert Wolter Mongisidi Hospital Manado. This was a descriptive study with a cross sectional design. Subjects were 39 third semester pregnant women who visited the Obstetric Department of Robert Wolter Mongisidi Hospital and fulfilled the inclusion criteria. The results showed that 25 subjects (64.1%) had low hemoglobin levels and 14 subjects (35.9%) had normal level of hemoglobin. In conclusion, most third semester pregnant women had low hemoglobin levels.Keywords: hemoglobin rate, third trimester pregnant women, anemia Abstrak: Hemoglobin (Hb) darah merupakan parameter yang digunakan untuk menetapkan prevalensi anemia. Nilai normal Hb pada akhir kehamilan rata-rata 12,5 g/dL, dan sekitar 5% wanita hamil konsentrasinya kurang dari 11,0 g/dL. Nilai Hb dibawah 11,0 g/dL terutama pada akhir kehamilan perlu dianggap abnormal dan biasanya disebabkan oleh defisiensi besi dan bukan karena hipervolemia yang umumnya ditemukan pada kehamilan. Penelitian ini bertujuan untuk mengetahui kadar hemoglobin pada ibu hamil trimester III di Rumah Sakit Robert Wolter Mongisidi Manado. Jenis penelitian ialah deskriptif dengan menggunakan desain potong lintang. Subyek penelitian ialah 39 ibu hamil trimester III yang berkunjung di Poliklinik Kebidanan di Rumah Sakit Robert Wolter Mongisidi Manado yang memenuhi kriteria inklusi. Hasil penelitian menunjukkan 25 subyek (64,1%) memiliki kadar hemoglobin rendah dan 14 subyek (35,9%) memiliki kadar hemoglobin normal. Simpulan penelitian ini ialah sebagian besar ibu hamil trimester III memiliki kadar hemoglobin rendah.Kata kunci: kadar hemoglobin, ibu hamil trimester III, anemia

Purpose The purpose of this paper is to improve the antifriction and antiabrasive behavior of the used oil through the addition of a lubricant. Design/methodology/approach The author selected 85W-90 used oil with three kinds of 4,758, 10,507 and 16,223 km mileages, which may represent run-in wear period, steady-state wear period and rapid wear for used oil, respectively. Nano copper, molybdenum dithiocarbamate (MoDTC) and copper dioctyl dithiocarbamate (CuDTC) of lubricant additive are added to the used oil to improve its antifriction performances and service life. The influence of lubricant additive on the tribological properties of used oil is investigated by the friction tests. Findings An abnormal phenomenon has been observed by the friction test under high mileage used oil with CuDTC in presence of MoDTC lubrication, and superlow friction coefficient of 0.04 has been achieved after a running-in period for the first time. It is found that CuDTC additive is beneficial to improve greatly the antifriction behavior of used oil, especially when MoDTC is present. The results indicate that the dissoluble of CuDTC and the tribochemical reaction of MoDTC play an important role in superlow friction of high mileage used oil. Moreover, the superlow friction is also closely related to the viscosity of used oil. Originality/value The possible mechanism of superlow friction is attributed to the additive thinning effect and the synergistic effect of the dissoluble of CuDTC and the tribochemical reaction of MoDTC binary lubricant additives in high mileage used oil. This work will extend the application of CuDTC additive widely and explore a new method to the reutilization and the life extension of used lubricating oil.

Abnormal Phenomenon

The number of the high slope along the highway is much more, except this, the geological conditions is complex. To ensure the driving safety and the normal operation of the highway, it’s meaningful to monitor the deformation trend of high slope and discover abnormal phenomenon timely and treat it. The paper taking freeway high slope monitoring project as an example, study the purpose of high slope stability monitoring, the monitoring method and the setting of the monitoring net. It also analysis the monitoring results. The results show that the monitoring spot displacements of the slope are small and there is no symptom to occur geological disaster such as landslide, slump, avalanches and so on. The slope is basically stable. The monitoring result has verified the feasibility and the effectiveness of the monitoring scheme. Expecting this can offer reference and gather experience for similar projects
