The collapse of posterior prosthesis teeth also results in the loss of the normal occlusal plane and the reduction of the vertical dimension.

The compressional, mechanical and dissolution properties were analyzed using density, crushing strength and dissolution methods. The result obtained showed that tablets made with ginger starch had acceptable crushing strength and dissolution rate. The disintegration time for 2%, 4% and 6% w/w ginger starch were 22.25, 17.07 and 33.17 minutes respectively and that for cassava starch 34.24, 29.16 and 33.35 minutes respectively. The 2% w/w of the ginger and cassava starches did not fall within the standard limit of the hardness test (4–8 kg) but rather values of 8.55 kg and 8.45 kg respectively were obtained and this may be linked to the thresh hold of the concentration of the binder not being attained. All the formulations passed the qualitative analysis but that consisting of 4% w/w ginger starch performed excellently in the entire tests hence ginger starch of such concentration could be a very suitable excipient for ibuprofen tablet formulation as compared to cassava starch of the same percentage composition.

They impact such properties to the tablet formulation by ensuring that the tablet remains intact after compression as well as improving free powder flowing quality . Binders have been used as solutions and in dry form depending on nature of another ingredient in the formulation and method of preparation. The choice of a particular binding agent depends on the binding force required, compatibility with other ingredients, particularly the active pharmaceutical ingredient (API) .

Its situation is worsened by the presence of multidrug-resistant (MDR) strains of M. tuberculosis. In ancient time, it was considered a curse. Tuberculosis started to reemerge in the early 1990s. The completion of the first whole genome sequence of M. tuberculosis was in 1998. Multi drug resistant (MDR)-TB is caused by strains of M. tuberculosis that resistant to at least rifampicin and isoniazid. Worldwide India is the country with the highest-burden of both TB and MDR-TB. Isolation of MTB on solid media followed by subsequent DST on solid media is easy to perform in the lab. They are time-consuming classical laboratory tests methods. So the molecular method is preferable to detect MTB. Different types of tool are available to detect MDR-TB, XDR-TB.

Production of potato in the Sudan savanna agro-ecological zone of Nigeria is restricted to periods of low temperatures that prevailed from early November to late February. The general approach for potato in this region is to relate the planting date to coincide with the period of relatively low temperatures, as high temperature inhibits growth and yield. It is in view of the above that field experiments were conducted in two locations at the Teaching and Research Farm of the Kebbi State University of Science and Technology, Aliero, during 2016/2017 dry season. The aim was to determine the most suitable potato variety and most appropriate planting date in the study area. Treatments consisted of factorial combinations of four Planting dates (1 st November, 15 th November 1 st December and 15 th December 2016) and four potato varieties (Bertita, Diamant, Lady-christl and Nicola). The experiments were laid out in a Randomized Complete Block Design with three replications. Results revealed that number of tubers per plant, weight of tubers per plant, mean tuber weight, mean tuber diameter and fresh tuber yield were higher when planted on 1 st 15 th November. Bertita proved to be the most robust in terms of growth; and with Nicola, in terms of yield compared to the other varieties. Based on the results of this study, it could be concluded that planting of potato from 1 st November to 15 th November coupled with either Bertita or Nicola give the highest potato yield in the study area.
