Prepositions in Krio

This paper is part of Peter Svenonius’ Adposition Seminar at the University of Tromsø which was taught in 2005-2006. The main focus was the distinction between locative path and locative place constructions. The aim of this paper is descriptive in nature and focuses on the complete prepositional system of Krio, an English-based Creole language spoken in Sierra Leone. The paper starts with a general introduction to prepositions in Krio. Three different categories are distinguished. This is followed by a description of each preposition individually and a discussion of intransitive prepositions and verb-particle constructions

Policy-Relevant Short-Term Consequences of Anthropogenic Greenhouse Disturbance

This study was triggered by recent publications in various periodicals, all indicating that an issue is newly coming up in the field of greenhouse science, viz. increased frequency in the near future of extreme climate events. Such threatening consequences of the greenhouse gas levels, still rising due to the passivity of the international community to take measures for lowering the emission of these gases, probably could more easily yield a consensus, at least in the industrialized world, that such measures have to be taken. The alternative will lead to a climate change where "any impact of a greenhouse warming on extreme climatic events will for many decades be far larger than the greenhouse effect itself" (Fred Pearce, New Scientist, 6 January, 1990, p. 31)

Managing Capacity by Drift Control

We model the problem of managing capacity in a build-to-order environment as a Brownian drift control problem and seek a policy that minimizes the long-term average cost. We assume the controller can, at some cost, shift the processing rate among a finite set of alternatives by, for example, adding or removing staff, increasing or reducing the number of shifts or opening or closing production lines. The controller incurs a cost for capacity per unit time and a delay cost that reflects the opportunity cost of revenue waiting to be recognized or the customer service impacts of delaying delivery of orders. Furthermore he incurs a cost per unit to reject orders or idle resources as necessary to keep the workload of waiting orders within a prescribed range. We introduce a practical restriction on this problem, called the $Ss$-restricted Brownian control problem, and show how to model it via a structured linear program. We demonstrate that an optimal solution to the $Ss$-restricted problem can be found among a special class of policies called deterministic non-overlapping control band policies. These results exploit apparently new relationships between complementary dual solutions and relative value functions that allow us to obtain a lower bound on the average cost of any non-anticipating policy for the problem even without the $Ss$ restriction. Under mild assumptions on the cost parameters, we show that our linear programming approach is asymptotically optimal for the unrestricted Brownian control problem in the sense that by appropriately selecting the $Ss$-restricted problem, we can ensure its solution is within an arbitrary finite tolerance of a lower bound on the average cost of any non-anticipating policy for the unrestricted Brownian control problem

Resource efficient collagen extraction from common starfish with the aid of high shear mechanical homogenization and ultrasound

Processes currently used for collagen extraction are complicated requiring a great deal of time and chemicals. Here, high shear mechanical homogenization (HSMH) and ultrasound (US) were integrated in the pretreatment step of collagen extraction from common starfish to reduce chemical use and time consumption. Effects of the assistant technologies on yield, structural integrity and functionality of collagen were also investigated. HSMH reduced the deproteinization time from 6\ua0h to 5\ua0min and its required amount of alkali 4 times, compared with classic methods. HSMH\ua0+\ua0US reduced the demineralization time from 24\ua0h to 12\ua0h and improved its efficiency in extraction of minerals. Collagen extraction with HSMH and HSMH\ua0+\ua0US resulted in similar yield as the classic method and did not affect triple helical structural integrity, polypeptide pattern, thermal stability or fibril-formation capacity of the collagens. Altogether, HSMH and US can effectively improve resource efficiency during collagen extraction without imposing negative effect on collagen quality

BEYOND DISRUPTIVE ELEARNING: HOLISTIC HEALTH INTEGRATED LEARNING CONCEPT

The main objective of this study was aimed to propose an Integrated Learning Concept (ILC) for holistic healthcare. The ILC was developed to alleviate the crisis from the fact that people around the world, including Thailand, can now access a substantial amount of health care knowledge from various online sources, however, the percentage of ailment and premature death from non-communicable diseases (NCDs) is still high. With a literature review, the researcher’s direct experience as a pharmacist in Thai traditional medicine as well as an in-depth expert interview, ILC was designed to provide learners self-medicated healthcare knowledge and inspire learners to change the everyday choice they made to enhance their state of wellness. ILC was beyond disruptive eLearning. It was a blended learning approach that integrated online learning (a combination between traditional eLearning and online social learning) and traditional classroom with standard health check and Dhatu check. ILC was designed to disrupt the idea that traditional eLearning is the approach that best fits with all dimension of learning. ILC was developed to overcome the shortcomings of eLearning and to enable people to have better comprehension in holistic healthcare. And once the development was finished, ILC shall be tested by comparing with a traditional eLearning class

Combined effects of isolation temperature and pH on functionality and beany flavor of pea protein isolates for meat analogue applications

The combined effects of isolation temperature (20, 30 and 40\ua0\ub0C) and pH (2.0–12.0) on yield, techno-functional properties, and beany flavor of pea protein isolates were investigated. Increasing pH from 2.0 to 9.5 and 11.0 increased yields from 37\ua0% to 75\ua0% and 79\ua0%, respectively, at 20\ua0\ub0C. At a constant pH, increasing temperature from 20 to 40\ua0\ub0C did not increase protein recovery; rather, negatively affected the techno-functional properties such as protein solubility, foaming and gelation. Protein isolated at pH 11.0 (20\ua0\ub0C) provided a higher fat absorption, gelation capacity, gel hardness, cohesiveness, chewiness, and gumminess than at pH 9.5, due to higher protein denaturation as supported by their higher surface hydrophobicity. Volatile beany flavor marker hexanal was predominant in all isolates than the starting material, irrespective of isolation temperature, probably due to lipid oxidation. The results provide a basis for tuning the isolation process for producing pea protein isolates with desired techno-functional properties for meat analogue applications
