A constraint is a limitation or a restriction that poses a threat to the performance and efficiency of a system. This paper presented a tactical review approach to production constraints modeling. It discussed the theory of constraints (TOC) as a thinking process and continuous improvement strategy to curtail constraints in other to constantly increase the performance and efficiency of a system...

  Cryptosporidium species are one of the most common causes of gastrointestinal infection in humans around the world. This study has aimed to investigate the hyper variable region of the 18S rRNA gene in Cryptosporidium for exact parasite identification .   DNA was extracted from 26 fecal samples from which initially Cryptosporidium oocysts were identified by Ziehl-Neelsen acid-fast , Auramine ...

Is the use of an online course delivery format, when compared with the more traditional face-to-face format, good or bad in the context of university education? Those who subscribe to the no-significant-difference perspective argue that online delivery is good, because it allows students with time and geographic distance constraints to obtain the education that they need, with no significant ne...

Point of Departure " First Law of Geography " : " Everything is related to everything else, but near things are more related than distant things. " — Waldo Tobler, 1970 Fundamental Dialectological Postulate: " Geographically proximate varieties tend to be more similar than distant ones. " — Nerbonne & Kleiweg, 2007 Tested on different types of data (surveys, corpora) Several kinds of geograph...

Understanding the evolution of body size and sexual size dimorphism has been a longstanding goal in evolutionary biology. Previous work has shown that environmental stress can constrain male-biased sexual size dimorphism at the population level, but we know little about how this might translate to geographical patterns of body size and sexual size dimorphism at the species level. Environmental ...

In this paper, we investigate the common scenario where every candidate item for recommendation is characterized by a maximum capacity, i.e., number of seats in a Point-of-Interest (POI) or size of an item’s inventory. Despite the prevalence of the task of recommending items under capacity constraints in a variety of settings, to the best of our knowledge, none of the known recommender methods ...

Background Despite Indonesia’s health status improvement over the last decade, special efforts to achieve the MDGs goals are still warranted, especially in maternal, neonatal, and child health (MNCH). However, the current centrally driven MNCH policies do not address the geographical disparities and the different constraints faced by Indonesian provinces and districts. Moreover, the MNCH slow p...

In real-time collaborative groupware, shared objects are replicated on distant geographical sites. Each user works on his own copies. This implies the divergence of different copies. Operational transformation approach makes it possible to reconcile the divergent copies. It allows to ensure the syntactic consistency of the copies by ensuring: convergence, causality and user intention. Although ...

persian and arabic have had long-lasting religious and cultural symbiosis. due to their speakers’ similar cultural conditions and geographical proximity, the two languages have lived a long time near each other, have grown together and enriched each other. the authors of this article studied the word formation processes in the two languages and showed the capabilities and limitations of each of...
