Published: May 2020

The laboratory induced cellular stress on zygotes and embryos in their microenvironment could negatively influence the clinical outcome. One of the core components of an IVF lab is the culture incubator. Incubators can provide a stable and appropriate-culture environment by regulating optimal conditions on parameters such as temperature, gas levels and humidity. Clinical studies which compare incubator characteristics may provide insight to their efficacy. In humid conditions of the tropical climate, the incubators without humidifiers can also be used. Hence this study was done to identify the role of a humidifier in a tropical country. In this multicentre retrospective study, embryos from a total of 787 patients were cultured as two groups -A and B in two different types of incubators- humidified and dry, respectively. 647 patients in group A and 140 patients in group B were examined for the developmental parameters. The embryos were frozen at the blastocyst stage and replaced in subsequent frozen embryo transfer cycles. The resulted pregnancy, miscarriage and the clinical pregnancy outcomes were compared. The data was subjected to statistical validation. There was no significant difference observed in the clinical pregnancy rates between the groups. This study validates the possible use of dry incubators for the in vitro culture of human embryos in tropical climate without aiding any humidification.

ABSTRAKRacing line merupakan daerah lintasan yang berguna untuk pebalap atau pengemudi mendapatkan akselerasi maksimum. Dalam penelitian mobil listrik, racing line tidak hanya berguna untuk mendapatkan akselerasi maksimum, namun juga berguna untuk mendapatkan hasil efisiensi tertinggi terutama pada saat mobil berada di tikungan, hal ini disebabkan mobil listrik menghasilkan daya yang lebih besar pada saat berada di tikungan dibandingkan dengan lintasan lurus. Pemilihan racing line serta proses kontrol kecepatan pada mobil listrik yang baik pada tikungan bertujuan untuk mengurangi konsumsi daya pada motor serta meningkatkan hasil efisiensi mobil. Untuk dapat meningkatkan hasil efisiensi pada mobil listrik perlu ditambahkan sebuah ECU (Electronic Control Unit) dengan kontrol fuzzy logic sebagai pengendali kecepatan mobil secara otomatis pada saat mobil berada di tikungan, dengan penambahan kontrol fuzzy logic serta sensor sudut belok ini konsumsi daya yang dihasilkan oleh mobil saat berada di tikungan menjadi lebih rendah serta hasil efisiensi mobil lebih tinggi.Kata kunci: Racing Line, Sistem ECU, Logika Fuzzy ABSTRACTIn the research of electric cars, the racing line is not only useful for getting maximum acceleration, but it is also useful to get the highest efficiency results especially when the car is round the corner, this is due to electric cars producing greater power when in a curved compared to a straight track. The selection of a racing line and speed control process on a good electric car on the curved aims to reduce the power consumption of the motor and increase the efficiency of the car. To be able to increase the efficiency of the electric car, an ECU (Electronic Control Unit) is added by fuzzy logic controls as a car speed controller automatically when the car is in the corner, with the addition of fuzzy logic controls and turn-angle sensors. The car when on the curved becomes lower and the results of higher car efficiency.Keywords: Racing Line, ECU System, Fuzzy Logic

Kegiatan magang bertujuan untuk meningkatkan kemampuan dan pemahaman dalam pengelolaan perkebunan kelapa sawit. Kegiatan magang dilaksanakan di Kebun Adolina. Dalam pelaksanaan magang, manajemen panen dalam kegiatan panen kelapa sawit diutamakan untuk diamati dan dipelajari. Pengamatan dalam manajemen panen terdiri atas: rotasi panen, kerapatan panen, taksasi produksi harian, kebutuhan tenaga panen, kriteria matang panen, kapasitas pemanen, mutu buah dan pengangkutan buah ke pabrik kelapa sawit. Data yang diperoleh dianalisis secara kuantitatif menggunakan rata-rata, persentase dan standar deviasi (statistik deskriptif) serta uji t-student (komparasi). Hasil yang diperoleh menunjukkan bahwa manajemen panen kelapa sawit di Kebun Adolina perlu ditingkatkan. Hal ini karena kapasitas pemanen yang lebih rendah dari standar perusahaan dan tingginya persentase produksi buah yang tidak bermutu. Rendahnya kapasitas pemanen berpengaruh terhadap perhitungan kebutuhan tenaga panen dan terganggunya rotasi panen. Rotasi panen yang terganggu berpengaruh terhadap tingginya persentase produksi buah yang tidak bermutu. Kebun Adolina telah melaksanakan taksasi kerapatan panen yang cukup akurat terhadap kerapatan panen realisasi. Keakuratan taksasi kerapatan panen terhadap kerapatan panen realisasi berpengaruh terhadap keakuratan taksasi produksi harian serta perhitungan kebutuhan tenaga panen dan angkutan panen.

Background: HIV (Human Immunodeficiency Virus) and AIDS (Acquired Immunodeficiency Syndrome) pandemic is a major challenge that health care workers are faced with because of increased risk of infection. Despite the high risk of HIV infection among nursing assistants, less attention is currently paid to training this cadre of hospital staff to reduce the risk of infection. Objective: To assess the effect of educational intervention on knowledge, attitude and practice about HIV/AIDS among hospital orderlies in two tertiary facilities in Ogun State, South-west, Nigeria. Methods: The study was a quasi-experimental, non-randomized, controlled group design which was conducted in three phases; a pre-intervention evaluation, immediate post-intervention evaluation and another evaluation three months post-intervention. Hospital orderlies were recruited (108 from the Olabisi Onabanjo University Teaching Hospital, Sagamu (OOUTH) as intervention group and 112 orderlies from the Federal Medical Centre (FMC), Abeokuta as controls). Results: Significant increase in the knowledge, attitude and practice of the intervention group determined by percentage score was recorded immediately after the training. In the control group, there was a decline in the attitudinal score but an insignificant increase in the knowledge and practice of HIV prevention. Three months post-intervention, further increase in the knowledge score and attitudinal score in the intervention group respectively compared to the pre-test scores ( 83.3% vs. 99.1% and 94.4% vs. 96.3%) were recorded. Conclusion: The study showed good knowledge of HIV and AIDS which further improved after the educational intervention. Therefore, the need for continuous training for the hospital orderlies is germane.

Background: Breast cancer is the most common female malignancy in Nigeria. Neoadjuvant chemotherapy is the first line treatment for locally advanced breast cancer. The advancement of many cancers is accompanied by inflammation, and inflammatory cells play an essential role in the progression. Objective: To determine if haematological parameters can predict the responsiveness of breast cancer to neoadjuvant chemotherapy regime. Method: A prospective cohort study of all breast cancer patients who had neoadjuvant chemotherapy between July 2017 and December 2018 was carried out. Haematological parameters of red cell count (RCC), white cell count(WCC), neutrophil count (NC), lymphocyte count (LC), platelet count (PC), red cell distribution width (RCDW), mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) were measured. Response to chemotherapy was assessed by measuring the longest diameter of the lump and largest lymph node and applying the UICC criteria. Results: Thirty-five females with breast cancer with the age range of 33-82 years and mean age of 48 ± 11 years were studied. The overall clinical response rate was 80% consisting of 40% complete clinical response, 40% partial clinical response, 8.6% stable disease and 11.4% progressive disease. Eleven (78.6%) with PLR values below average had good clinical response while 21.4% of those with PLR value above average had a good clinical response (χ2 = 8.4, p = 0.006) Conclusion: The study showed that PLR is associated with complete clinical response to neoadjuvant chemotherapy and should be used as part of routine assessment before chemotherapy.
