An Analytical Formulation for Pollutant Dispersion Simulation in the Atmospheric Boundary Layer

引用

Journal of Environmental Protection 2013年第8期4卷 57-64页

作者： Glenio A.Goncalves regis S.de Quadros Daniela Buske Federal University of Pelotas(UFPel) Department of Mathematics and Statistics(IFM/DME)PelotasBrazil

In this work we present the solution of the two-dimensional advection-diffusion equation by the GILTT method. The GILTT approach uses, in the series expansion, eigenfunctions given in terms of cosine functions. Here, a different expansion for the solution of the advection-diffusion equation will be explored. In other words, a Sturm-Liouville problem carrying more information of the original problem is considered, given by Bessel functions. Numerical simulations and comparisons with experimental data are presented.

Open Journal of Applied Sciences 2024年第7期14卷 1730-1753页

The waveguide which is at the center of our concerns in this work is a strongly flattened waveguide, that is to say characterized by a strong dispersion and in addition is strongly nonlinear. As this type of waveguide contains multiple dispersion coefficients according to the degrees of spatial variation within it, our work in this article is to see how these dispersions and nonlinearities each influence the wave or the signal that can propagate in the waveguide. Since the partial differential equation which governs the dynamics of propagation in such transmission medium presents several dispersion and nonlinear coefficients, we check how they contribute to the choices of the solutions that we want them to verify this nonlinear partial differential equation. This effectively requires an adequate choice of the form of solution to be constructed. Thus, this article is based on three main pillars, namely: first of all, making a good choice of the solution function to be constructed, secondly, determining the exact solutions and, if necessary, remodeling the main equation such that it is possible;then check the impact of the dispersion and nonlinear coefficients on the solutions. Finally, the reliability of the solutions obtained is tested by a study of the propagation. Another very important aspect is the use of notions of probability to select the predominant solutions.

目的:对比聚合酶链反应(PCR)和细胞分离培养在实验室诊断眼部单纯疱疹病毒(HSV)感染疾病的作用。方法:我们对连续患者的实验室结果(PCR实验,细胞分离培养及临床诊断)及病历进行回顾性研究在诊断眼部HSV感染疾病过程中,PCR检测结果、细胞分离培养及首诊结果进行了统计比较。结果:患者581例经过检查后,520例PCR检查阴性,细胞培养阴性(89.6%);0例PCR检查阴性,细胞培养阳性(0%);27例PCR检查阳性,细胞培养阴性(4.6%);34例PCR检查阳性,细胞培养阳性(5.8%)。PCR检测阳性率高于细胞分离培养(McNemars,P=0.0001)。47例PCR检查为HSV初诊感染阳性患者中,19例患者中有14例为细胞培养阴性结果(74%),5例HSV患者因缺PCR检测结果将被误诊;28例患者中有25例患者细胞培养阳性(占89%),3例HSV患者因缺PCR检测结果将被漏诊。结论:PCR诊断眼部HSV感染优于细胞分离培养。细胞分离培养对于眼部HSV感染的非典型表现不易诊断。

目的:厌氧细菌可引起眼部感染,我们测试OxyPlate^(TM)厌氧系统(OxyPlate^(TM) Anaerobic System,OXY)隔离可引起眼部疾病的厌氧细菌。方法:OXY不需要直接的厌氧条件(比如厌氧袋,罐),将其与常规的厌氧袋培养基相比。琼脂培养基上眼部厌氧细菌菌株在好氧和厌氧条件下(厌氧袋)行标准的菌落计数:(1)OXY(好氧);(2)5%羊血(sheep blood,SB);(3)巧克力琼脂;(4)Schaedler琼脂。测试的眼部体外培养细菌来自眼内炎,泪囊炎,包括10个丙酸杆菌和3个放线菌种类。在每个培养条件下,每个细菌菌落计数隔离,排名从大到小,并在非参数比较下确定最佳的培养条件。结果:所有的厌氧条件对于厌氧菌株呈阳性反应。厌氧菌在有氧条件下的SB和Schaedler的琼脂中无法增长。痤疮丙酸杆菌在巧克力琼脂中生长稀疏。作为一种厌氧系统,在厌氧袋SB分离比OXY(P=0.0028)和巧克力琼脂(P=0.0028)分离出更多的菌落数。结论:虽然OXY经测试并没比其他的厌氧系统更高效,它似乎是一个合理隔离厌氧细菌的替代方法。其琼脂培养基在一个专门设计的盘并不需要厌氧袋使得OXY优于其他厌氧系统。

A Survey on Pattern of Ocular Morbidity in a Rural Community in Rwanda

引用

Open Journal of Ophthalmology 2019年第2期9卷 54-63页

作者： Kingsley Ekemiri Lilian Omondi Marie Josee Uwisunze Francois regis Twiringirimana Denys Ndayambaje Fiston Kitema Department of Ophthalmology College of Medicine and Health Sciences University of Rwanda Kigali Rwanda

Background: Majority of ocular morbidities found in developing countries are preventable and curable and vary from country to country and from community to community. Screening of ophthalmic conditions in communities with underserved ophthalmic services, can help detect and treat various spectra of ocular morbidity. Untreated ocular conditions may lead to vision impairments and blindness. Methods: A free walked-in ophthalmic screening outreach survey was conducted at a rural community in Rwanda and the total number of attendees was 762. Patients’ demographics, detailed case history, and ophthalmic specific evaluation tests generated the survey data. Treatment offered was based on the diagnoses made. Patients who required special treatment or reviews were referred to the health care facilities for further investigations and subsequent management. The recorded data on observation forms were analyzed by Statistical Package for Social Sciences (SPSS) computer software using descriptive statistics. Results: Majority (91.5%) of the patients were from Mageragera community where the outreach was conducted. The number of females 71.7% (546) seen were more than males 28.3% (213) in the ratio of 2.5:1. Age group with the highest number of patients was (1 - 10) years, 139 (18.2%) while the least was ≥71 years, 34 (4.5%). Among ocular morbidities diagnosed, conjunctivitis ranked highest 562 (73.8%), followed by refractive errors 118 (15.5%) and cataract 31 (4.1%). Glaucoma was diagnosed in 4 (0.5%) clients. Medication given included steroidal, non-steroidal and antibiotics ophthalmic drugs. Conclusion: A total of 762 patients benefited from early diagnoses, treatment and referrals. The pattern of eye diseases observed was similar to other reports from other developing countries. Statistics from this survey provides baseline data which can be used for planning, management and prevention of ocular conditions in the studied community as well as in research.

We compute rational points on real hyperelliptic curves of genus 3 defined on whose Jacobian have Mordell-Weil rank r=0. We present an implementation in sagemath of an algorithm which describes the birational transformation of real hyperelliptic curves into imaginary hyperelliptic curves and the Chabauty-Coleman method to find C (). We run the algorithms in Sage on 47 real hyperelliptic curves of genus 3.

Preparation Characterization and Thermal Behaviour of Carbopol-TiO<sub>2</sub>Nanocomposites

Composites consisting of carbopol (CP) and ceramic titanium dioxide nanoparticles, TiO2 have been investigated. The CP-TiO2, organic-inorganic hybrid composites have been prepared in DMF by heating the mixture with a constant rate of 1。C/min, up to 30。C, 45。C, 60。C, 80。C, 100。C and 120。C. Proprieties such as absorption, structure and external aspect of the obtained materials were investigated by Uv-vis, FTIR, DRX and SEM analyses. The X-ray diffraction patterns confirmed that the TiO2 nanoparticles maintained their original tetragonal anatase-type crystalline structure in the composites. The chemical structure of the obtained materials was determined by ATR-FTIR spectroscopy. The influence of TiO2 nanoparticles on the thermal proprieties of carbopol matrix was investigated using thermo-gravimetric analysis and differential scanning calorimetry. The glass transition temperature (Tg) of the carbopol matrix was considerably increased by the presence of ceramic feller nanoparticles and its thermal stability was significantly improved. Furthermore the water loss which represents 7.56% of the weight loss in pure CP at 100。C was avoided in the CP-TiO2 nanocomposites at this same temperature. This important finding revealed that ceramic fellers blocked the water loss in the modified carbopol nanocomposites, which stayed stable till 200。C.
