Faculty of Infectious and Tropical Diseases,London School of Hygiene and Tropical Medicine, London, UK The acoustic ceiling tiles are usually made from mineral fiber, synthesized from many materials like clay, perlite, newsprint, etc., which are great at absorbing the noise and reducing the room echo.

The results of microscopic examination from the cross-sectional survey 12months after the implementation will be compared between the intervention arm and the control arm, based on cluster-level summaries using the two-stage procedure [ 27]. In the first stage, an individual-level logistic regression model will be constructed with adjustments for confounders, including age, gender, bed net use, house structure, and SES, and a fitting value will be summarized for each cluster using the model. In the second stage, a residual from the fitted values and the observed values for each cluster will be computed. The difference between the two groups will be tested using Wilcoxon’s rank-sum test by ranking cluster-level summaries.

Flat ceilings are the conventional type of ceilings that are just as beautiful as architectural designs. They are the most popular and common ceilings that can be enhanced by adding trays or wooden beams. In fact, there are hundreds of different ways you can design your drywall flat ceiling to your liking by adding moldings or lighting features. Coffered ceilings are patterned just like tray ceilings, but the only difference is their multiple recessed areas add dimension, unlike tray ceilings that make the room feel smaller. Malaria prevalence in children will be estimated using cross-sectional malariometric surveys in schools. These surveys will be conducted at baseline (before ceiling net installation), 6months, and 12months post-installation. In addition, class rosters will be cross-referenced with the community census to determine the allocation of each eligible student in the trial clusters.In the intervention arm, Olyset®Plus ceiling nets will be installed in all dwelling units where residents sleep, free of charge to the households. All participants will be encouraged to continue to use LLINs, distributed by the Homa Bay County government. A typical flat ceiling consists of an 8-feet vertical continuation from the floor with no architectural features. This conventional ceiling type was usually covered with “ popcorn” texturing that hid the imperfections; however, it traps dirt and dust, which often pose a cleaning and painting challenge. Some can even make the room look darker, hence the reason why most people prefer flat and plain ceilings in a neutral color. 5. Tin Ceilings O menor valor integral maior ou igual a a. Se a for igual a NaN, NegativeInfinity ou PositiveInfinity, esse valor será retornado. Observe que esse método retorna um Double em vez de um tipo integral. Exemplos Most vaulted ceilings tend to have exposed beams, which are the architectural focal points of a living room or in fact any room of the house, including bathrooms. A vaulted ceiling can also be used with beadboard to create a stylish design for the room just like the image above. A suspended ceiling can also feature textures, fiber panels, or even geometric designs. But before installing such ceilings for your home, take into account the size of the room as ample ceiling space is required. 2. Shed Ceilings

This study has several limitations. First, the visible nature of the ceiling net makes it impossible to blind study participants and field research staff. However, microscopists and laboratory technicians who process and analyze samples are blinded to the study arm assignment of participants. Indoor resting mosquitoes will be collected by pyrethrum spray catches and CDC light traps to determine vector density, which should be free of assessor bias. Second, since we hypothesize that schoolchildren will benefit the most from the additional protection of the ceiling net, our primary outcome is the prevalence of Plasmodium infections in children aged 3 to 15years old. This will be assessed by school-based cross-sectional surveys. However, the benefit of the ceiling net will likely be extended to other age groups who share the same dwelling units. While we plan to examine the impact in a longitudinal cohort, the present cohort is small relative to the scale of the intervention. As such, findings in this cohort may not be generalizable to the trial population. Third, given that the ceiling nets are visible and thought to function in ways similar to conventional LLIN, it is conceivable that participants in the intervention arm may lower their usage of conventional LLIN, effectively relying on the ceiling net as a replacement rather than an addition to conventional LLIN for malaria protection. Continuous community engagement throughout the trial period will help to reinforce the importance of consistent LLIN use. Bi-weekly interviews with cohort participants will provide data on the pattern of LLIN use after ceiling net installation. We will conduct surveys and in-depth interviews to elicit participants’ perceptions of the ceiling net, which can guide future messaging and implementation. Fiberglass tiles for ceilings are usually made from glass fibers in polymer coating and are considered to be a low-cost alternative to wood. There are numerous advantages to using this material for your ceiling. Fiberglass tiles are environmentally friendly materials that are lighter in weight than wood. A drywall ceiling is typically installed directly to the joists of the ceiling by taping the joints. Drywall is usually used on flat ceilings, but it can also be textured to act as noise insulation and to hide any imperfections. The most common ceiling texture materials for drywall include orange peel, splatter, and popcorn. Plaster The primary study objective is to determine the protective efficacy of Olyset®Plus ceiling nets in reducing malaria prevalence in children aged 3 to 15years old, during a 12-month follow-up period.The inclusion criteria for cross-sectional malaria and anemia prevalence surveys in schools are (1) age between 3 and 15years old, (2) living in the study area during the study period, and (3) informed consent being provided by the parent or legal guardian before each survey. The exclusion criterion is (1) having severe chronic illnesses. a 以上の最小の整数値。 a が NaN、 NegativeInfinity、 PositiveInfinity のいずれかに等しい場合は、その値が返されます。 このメソッドは、整数型ではなく Double を返します。 例
