Phase Field Model for Dynamics of Sweeping Interface

Motivated by the drying pattern experiment by Yamazaki and Mizuguchi[J. Phys. Soc. Jpn. {\bf 69} (2000) 2387], we propose the dynamics of sweeping interface, in which material distributed over a region is swept by a moving interface. A model based on a phase field is constructed and results of numerical simulations are presented for one and two dimensions. Relevance of the present model to the drying experiment is discussed.Comment: 4 pages, 7 figure

Hematological derangement patterns in Nigerian dogs infected with Trypanosoma brucei: A simple prototype for assessing tolerance to trypanosome infections in animals

The haematology of Nigerian local puppies experimentally infected with the Federe strain of Trypanosoma brucei was studied in a total of six 9-weeks old puppies born to two local bitches. Four were randomly selected and inoculated with about 0.8 x 106 of T .brucei subcutaneously and the remaining two served as the uninfected control. The parasitaemia was monitored daily using wet mount microscopy. The packed cell volume (PCV), red blood cell (RBC) counts, total and differential white blood cell (WBC) counts and rates of both red blood cell and white blood cell loss per day and per parasitaemia log equivalent value(LEV) were monitored twice in a week . Parasitaemia was detected in the infected group four days after infection which was followed by an acute disease course, though with low fatality rate in the dogs. The anemia was characterized by a fluctuating PCV decrease from the pre-infection value of 29.5±4.5% and 15.3±3.3% at two weeks after infection when one of the dogs died. There was a mild decrease in the overall erythrocyte values which was attributable to trypanotolerance in the local breed of dogs. The post infection hematological derangement pattern was characterized by an overall post-infection RBC count drop of 1.92+0.23(x 1012/μ) (39.0%), mean daily drop of 0.07+0.05 (x 1012/μ) and an overall drop per LEV of 0.69(x 1012/μ). The overall mean postinfection total WBC count drop was 0.61±0.15(x109/μ)(43.6%) with a mean daily drop of 0.02±0.14(x109/μ), and an overall drop per LEV of 0.22±0.44(x109/μ). There was an overall higher post infection leukocyte drop compared to erythrocyte. The result poses fundamental research questions on the likelihood of differential surface sialic acid contents of erythrocytes and leukocytes and the possible roles of trypanosome sialidase in creating this difference as well as enhancing pathogenesis of leucopenia in the dogs . It was concluded that the patterns of hematological derangements demonstrated as erythrocyte and leukocyte drop (loss) rates and drop per parasitaemia Log Equivalent Values could serve as a prototype for comparing susceptibility to animal and human T. brucei infections and, other trypanosome species.Keywords: Federe, Trypanosoma brucei, haematology, derangement, pattern

Karakteristik Ikan Pelagis Kecil Yang Dipasarkan Di Pasar Arumbai, Kota Ambon

Small pelagic fish play a crucial role in the marine food chain and have significant economic value, yet information about them remains scarce. This research aims to map the origin and characteristics of small pelagic fish marketed at Arumbai Market in Ambon City. The study was conducted over six months, from May to October 2023, at Arumbai Market. The research utilized survey methods and interviews, and the data were analyzed descriptively. Observations were made on the quantity and size structure of four dominant fish species from five different fish landing locations: Hila, Tulehu, Laha, Hitu, and Latuhalat. The results of this research revealed variations in the composition of dominant small pelagic fish species sold, from the highest to the lowest, namely Decapterus sp, Rastreligger sp, Selar sp, and Auxis sp. The contribution of the five fish landing locations is as follows: Hila (31%), Hitu (24%), Tulehu (18%), Laha (15%), and Latuhalat (12%). Differences in the composition of the quantity and size marketed are suspected to be due to variations in seasons, fishing tools, and capture areas

Uptake of Antenatal Care Among Pregnant Women in Plateau State Nigeria

Background-Antenatal care offers pregnant women promotive, preventive and curative services. Despite this, some pregnant women still donrsquot access ANC at all while others donrsquot have access to ANC by skilled health care professionals. This increases the risk of maternal morbidity and mortality. This study therefore aims to determine the predictors of ANC attendance among in Plateau State. Methodology-A community based cross sectional study,400 study participants across six communities in the three senatorial zones in Plateau State were selected. Focused Group Discussion was conducted among study participants. Data was analysed using SPSS version 23. Results- 90.8% of respondents booked their last pregnancy out of which 55.8% had more than four ANC visits. Only 52.9% of the women had ANC by skilled health care providers. 69.7% of women who did not book their pregnancy delivered at home. Educational status, marital status and marital setting were predictors of ANC attendance among the study population. Women who had formal education were 1.7 times more likely to attend ANC compared to those with non-formal or no education at all. (P-value lt0.001 CI 1.267-2.321). Also, women in monogamous settings were more likely to attend ANC compared to those in polygamous setting (P-value 0.015 CI 0.162-0.822). Conclusion-Many of the respondents did not have the required number of ANC visits.nbsp More targeted interventions should be implemented in order to ensure that women have access to skilled care during pregnancy as this will reduce the risk of complications in pregnancy and delivery

Class Position of Immigrant Workers in a Post-Industrial Economy: The Dutch Case

In this paper, the issue of changing labour-market opportunities and the position of members of minority groups in advanced service economies is addressed, focusing on the Dutch case. We distinguish between two social hierarchies, one of traditional ‘fordist’ occupations and one of post-fordist occupations. Compared to the native Dutch, all immigrant groups are over-represented at the bottom of the labour market, both in the fordist and in the postindustrial hierarchy. Increased immigrant labour-market participation in the 1990s was accompanied by a strong rise in the number of flexible labour contracts. Native Dutch also work more frequently on flexible labour contracts, but not to the same extent as immigrants. The lower occupational level of the Surinamese, Antilleans and other non-Western immigrants employed in post-industrial occupations can be attributed to their low educational level. This is not true, however, for Turks, Moroccans and other non-Western immigrants employed in fordist occupations. Their low occupational level can not be completely explained by their low educational level. The effects of changes in the economic structure differ for ethnic groups, depending on their past employment, their cultural capital and the institutional framework in which they have to operate
