So it is important to develop cold tolerance cultivars. In the present study, cold tolerance characters of 36 parents and 423 rice lines from 68 hybrid groups were investigated at seedling stage under low tempera- ture and sparse light conditions in field. There were 10 parent accessions with strong cold tolerance of level 1. Among them, 3 were common wild rice accessions; 4 were japonica rice cultivars; 2 were indica rice; 1 was offspring from hybrid be- tween indica and japonica.There were 33 lines with strong cold tolerance of level 1 from the hybrid groups of common wild rice,and 15 from the hybrid groups of IRBB5, and only 3 from the hybrid groups of BPHR96. There were abundant cold tolerance resources in rice germplasm. It was feasible to develop cold tolerance cul- tivars from the hybrids among common wild rice, japonica cultivars and indica culti- vars.展开更多

Relationship between compressive strength and Young’s modulus was obtained eventually. It is found that the compressive strength, flexural strength, and Young’s modulus of UHPC increase by 19.01%, 10.81%, and 5.99%, respectively, when 40 wt% cement is replaced with supplementary cementitious materials. The relationship between compressive strength and Young’s modulus of UHPC is an exponential form.展开更多

Uganda has high maternal and neonatal morbidity and mortality ratios, typical of many countries in sub-Saharan Africa. Recent findings reveal maternal mortality ratio of 435:100,000 live births and neonatal mortality rate of 29 deaths per 1000 live births in Uganda;these still remain a challenge. Women in rural areas of Uganda are two times less likely to attend ANC than the urban women. Most women in Uganda have registered late ANC attendance, averagely at 5.5 months of pregnancy and do not complete the required four visits. The inadequate utilization of ANC is greatly contributing to persisting high rates of maternal and neonatal mortality in Uganda. This study was set to identify the factors associated with late booking and inadequate utilization of Antenatal Care services in upcountry areas of Uganda. Method: Cross-sectional study design with mixed methods of interviewer administered questionnaires, focus group discussions and key informant interviews. Data was entered using Epidata and analyzed using Stata into frequency tables using actual tallies and percentages. Ethical approval was sought from SOM-REC MakCHS under approval number “#REC REF 2012-117” before conducting the study. Results: A total of four hundred one were enrolled with the majority being in the age group 20 - 24 years (mean age, 25.87 ± 6.26). Health workers played a great role (72.04%), followed by the media (15.46%) and friends (12.50%) in creating awareness about ANC. A significant number of respondents went to TBAs with reasons such as “near and accessible”, “my husband decided”, and “they are the only people I know”. 37.63% of the respondents considered getting an antenatal Card as an importance of ANC. 71 (19.67%) respondents gave a wrong opinion (late) on booking time with reasons like demands at work, no problems during pregnancy, advised by friends, just to get a card, long distance and others didn’t know. Almost half of the respondents never knew the recommended number of visits. Religion, occupation, level of education, and parity were found to influence place of ANC attendance, number of ANC visits and booking time. Husbands were necessary to provide financial support, accompany their wives ANC clinic, and ensure that they complete the visits. But their response was poor due to: fear of routine investigations and constrained economically. Conclusion: The study findings show the actual rural setting of ANC services attendance and utilization. Much sensitization has to be done specifically in these rural areas to empower pregnant women and their husbands as to improve ANC attendance and utilization.展开更多

The first part of the paper deals with the origins of white domination in South Africa, going back to mid-seventeenth century with the Dutch aggression against African tribes all the way through to the twentieth century and the appearance of the main political parties behind the ideology of apartheid. The second part of the paper focuses on the internal opposition to the segregationist state created by the whites in South Africa. Opponents came from different circles： intellectuals, politicians, churchmen, civil servants, lawyers, doctors, etc. But the most prominent opponent of Apartheid was the Africa National Congress （ANC） which was founded in 1912. The third and final part analyses the international struggle against apartheid in the United Nations forums. This opposition took first the form of political and diplomatic actions against the racial system of South Africa, and then was materialized by economic sanctions which revealed to be the most susceptible to affect seriously the apartheid regime.展开更多

This paper focuses on real-time hardware implementation of multi-tap adaptive noise cancellation （ANC） system by using the least mean square （LMS） algorithm on TMS320C6713 to remove undesired noise from a received signal for various audio related applications. Three different experiments are carried out by considering different audio inputs to test the efficiency of the designed ANC system. The ＇C＇ code implementation of LMS algorithm is introduced and simulated in code composer studio （CCS）, then realized on the digital signal processor （DSP） C6713. The 300 Hz, 500 Hz, 800 Hz, 1 kHz and 3 kHz of tone signals and male speech signal are used as the reference inputs to trace the noise of signal until it is eliminated. The performance of ANC system is studied in terms of convergence speed, order of the filter and signal-to-noise ratio （SNR）. The experimentam results demonstrate that the designed system shows a consider- able improvement in SNR.展开更多

Prenatal care is necessary, which is not often the case in our context. Aim: To analyze the influence of antenatal surveillance on maternal and perinatal prognosis. Patients and Method: Preliminary longitudinal and analytical survey at the Owendo University Hospital (OHU) over 6 months. It focused on prenatal surveillance. The study population consisted of parturients who gave birth within 24 hours and we studied sociodemographic characteristics, variables related to antenatal contact, those of delivery as well as maternal and newborn outcomes. Results: 2485 deliveries were recorded and 1300 patients were retained according to the inclusion criteria. No prenatal contact (ANC0) was performed in 93 (7.15%), insufficient (ANCI) in 943 patients (72.5%), and sufficient (ANCS) in 264 patients (20.30%). Patients with low school level were significantly found when the NPC was not performed or insufficient and the same was true for the group of patients who were not employed and those who were single (p < 0.005). The caesarean section rate and perinatal mortality are high in this case. Conclusion: The quality of prenatal contact is insufficient in our context. The absence or inadequacy of the latter has a strong negative impact on maternal and perinatal morbidity and mortality.展开更多

This innovative device features a dynamic noise modulation system that transitions between ANC and transparency modes, tailored to the acoustic needs of patient rooms, operating theatres, ICUs, and dental practices. It is designed for use in sleep laboratories to enhance rest and in audiometry rooms for precise auditory assessments. The portable and cost-effective design eliminates the need for traditional acoustic modifications. Post-ear surgery patients benefit from its calming auditory settings, while pediatric care is supported through its soothing properties. Its versatility extends to diagnostic imaging and recovery rooms, ensuring tranquil environments. Beyond healthcare, this ANC headphone has potential therapeutic applications, including vestibular rehabilitation, by supporting the recovery of the villi in semicircular canals. Its adaptability across environments such as libraries, mining, production industries, theatres, and urban noise landscapes highlights its broad utility. Although the ANC circuitry has been carefully designed, empirical validation is still pending. This manuscript explores the headphone’s diverse applications and its ability to transform noise management and auditory health across multiple domains. Tailored modes for specific scenarios, including traffic noise, emphasize its innovative potential as a key tool in auditory technology.展开更多
