Background: An open fracture is an injury in which the fracture site and/or hematoma communicates with the external environment. It is associated with significant morbidity and disability and is a challenge to the surgical team. The lower extremities are the most often exposed to traumatic injuries compared to other anatomical parts of the body. Patterns of open fractures differ with different mechanisms of injury and the segment of the long bone affected. The correct and timely management of open fractures is beneficial to the patients and leads to a more favorable outcome. This study aimed at describing the pattern of open fractures of long bones of the lower limb treated in 3 major hospitals of the south west region, Cameroon. Methodology: This was a hospital-based retrospective review of files of patients with open fractures of long bones of the lower limb managed at the surgical units of three secondary health facilities in the South-West region of Cameroon from the 1st of January 2015 to the 31st of December 2019. The socio-demographic characteristics, clinical presentation, treatment modalities, and outcomes were recorded. The data was stored and analyzed using Epi info version 7.0 and SPSS version 23.0 respectively. Results: A total of 195 files of patients aged 8 to 80 years were studied. The main age group affected was between 20 tyle

Objectives of this study were to investigate the effects of milk replacer (Mr) acidification for free- access feeding on pre- and post-weaning performance, morbidity and mortality of calves. Calves were randomly assigned to free-access feeding of acidified (ACID, n = 31) or non-acidified (NON, n = 31) Mr, and weaned at 42 days. ACIDMr was prepared to pH 4.0 - 4.5 using formic acid. Intakes were measured daily and weights weekly. Samples of ACID and NON Mr were analyzed for coliform and aerobic bacterial growth. After weaning, calves transitioned to a grain-fed veal diet, weighed every 2 weeks. At slaughter (approximately 6 months of age), lungs were evaluated for gross pathological changes and dressed carcass weights were obtained. Generalized linear mixed models were constructed to examine the effects of Mr acidification. Differences by treatment group for pre- and post-weaning morbidity and mortality were tested using Pearson’s χ2 and Fisher’s exact tests. ACID calves consumed less Mr than NON (10.6 vs. 11.7 L/d, P = 0.02). Acidification tended to promote earlier onset of starter ration consumption (32.0 vs. 39.5 d, hazard ratio = 1.5, P = 0.07), but did not affect average daily starter ration or water intakes across the pre-weaning period. ACID and NON calves did not differ for BW at weaning, pre- or post-weaning ADG or dressed carcass weight. ACID Mr had less coliform (P robic bacterial growth (P than NON Mr, but odds of disease treatment and mortality did not differ. ACID calves tended to have lower odds of pulmonary lesions during post-mortem inspection than NON calves (Or = 0.3, P = 0.07). these results indicate that under free-access feeding conditions, acidification limited bacterial growth and Mr intake, but there were no long-term impacts of acidification on calf performance or health. In conclusion, acidification to pH 4.0 - 4.5 will significantly reduce bacterial growth in milk fed to calves.

Half of altogether 60 cylindrical implant devices made of titanium-aluminum-vanadium alloy （ ti-6Al-4V） were plusna-sprayed with a hydroxyapatite-couting and the other half had a corundum blasted porous surface. 15 implants of each group of the titanium test buplants were coated with 230 μg porcine, high-purified BMP- 3-precipitute per implant. In each case a BMP- 3-couted and an uncoated control-device were implanted into the femoral part of the putellofemoral joint of the right and left leg of 30 adult giant rabbits. Histomorphological and histomorphometrical we found in both groups with BMP- 3-coated test devices an improved osteointegrution. Stutistical evaluation using the t-test for matched samples showed 5 weeks after surgery a significant higher volume of tony formed bone of the BMP- 3-coated corundum- blasted or hydroxyapathe- coated ti- 6Al- 4 V test devices compared to the non-couted controls of the same t）pe （p 〈 0.01, t-test for matched samples）. In both implant groups with BMP-couting a synergetic effect was verifiable although the bone ongrowth in the hydroxyaputite coated implants was more extensive than in the corundum blasted implants. Light microscopy demonstrated osteointegrution without connective tissue membrane around the surface of the implants. Our results indicate that composite metal implants,as used in endoprosthetics and implantology , are suitable carriers for BMP- 3 and im proved fixation of the implants can be achieved. the hydroxyapatite surface is superior to the corundum-blasted surface with regards to the observed parameters because of its pronounced bioactivity and its osteoconductive characteristics.

Novel ti6Al4V particles-reinforced AZ91 Mg matrix composites were successfully fabricated by stir casting method. the stirring time in semisolid condition directly affected the particle distribution and the quality of the ingots. Furthermore, the optimal speed of the heating and the liquid stirring could overcome particle settlement caused by the density difference between the matrix and the particles. ti6Al4V particles distributed uniformly in the composites with different particle contents. the average grain size decreased with the increase in the particle contents. the ti6A14V particles bonded pretty well with the alloy matrix. In addition, there were some interfacial reactions in the composites. there were rod-like A13ti phases at the interface. the precipitates extended from the particle surface to the matrix, and they might improve the interfacial bonding strength. the ultimate tensile strength, yield strength and elastic modulus were enhanced as the particle contents increased, and the elongation was much better than that of the same matrix material reinforced with SiC particles. thus, the novel composites exhibit better comprehensive mechanical properties.

With the current situation of insecurity in Nigeria and the worsening condition of Nigerian roads, there is increasing demand for air travel. this increasing demand for airline services amidst limited resources results in passenger dissatisfaction and reduction of revenue for airports and airlines. the dynamics of service demand and resource supply result in check-in issues for all the stakeholders in the commercial aviation industry. Hence, this research simulated the developed model for travelers’ check-in process at the “D Wing” of the Departure Section of Murtala Muhammed International Airport (MMIA), Ikeja, using Arena Software tool. the simulation of the developed model was carried out by varying five different configurations of the servers with respect to the baggage weighing machines and passenger profiling devices to obtain the minimum average check-in time (ACt) for the process, with each configuration undergoing 133 completions of simulation runs. the result of the experimentation revealed that the 3 × 3 × 4 configuration of servers produced the smallest ACt of 18.25 minutes. this translates to a difference of about 58 minutes from the 76.16 minutes ACt of the real system;representing about 76% improvement in the check-in time of passengers. this study contributed to knowledge by revealing that the main choke points in the MMIA check-in system occur at the baggage weighing and passenger profiling areas as against the check-in counter sub-section as advanced by previous works. Furthermore, the research added value to knowledge by creating a balance between customer satisfaction and cost of operations thereby accommodating the interests of the passenger and the operator who are the two main stakeholders in the commercial aviation industry.

试验采用4×4拉丁方设计,利用4头18月龄,体质量为(262±17.9)kg处于生长期的泰国沼泽性水牛,通过饲喂粗料中4种不同比例香根草的日粮,观察每单位可消化有机物质尿嘌呤衍生物排泄量(PD/DOMI)的变化,来研究不同日粮对水牛尿嘌呤衍生物(PD)排出量的影响.结果表明,随着香根草在粗料中比例的增大,尿囊素(Allantoin)、尿酸(Uric acid)及总嘌呤衍生物(total PD)的排出量都增加,且日粮间差异显著(Pthine+hypoxanthine)的排出量在各个日粮间差异不显著(P>0.05);PD/DOMI随着日粮中香根草含量的增加,在日粮间差异不显著(P>0.05).研究说明香根草占粗料50%时,对水牛尿嘌呤衍生物(PD)的排泄量影响最大(PD的排出量:17.5 mmol/d,PD/DOMI:6.11 mmol/kg).
