In order to improve the operating efficiency of mixture storage yard, the problem of multiple yard cranes scheduling (MYCS) must to be solved. The paper develops a multiple yard cranes scheduling MIP model in order to minimize the sum of trucks’ waiting cost and yard cranes’ moving cost. An important feature is that the future has to be taken into account: the interference between two yard cran...

the present study focuses on the formation of various types of yards in mosques and the elements that contribute to the respective process. the significance of the issue lies in that certain scholars have associated the yard in mosques with the concept of garden, and have not taken into account the elements that contribute to the development of mosque yards of various types. the theoretical fin...

An analog of the Falconer distance problem in vector spaces over finite fields asks for the threshold α > 0 such that |∆(E)| & q whenever |E| & q, where E ⊂ Fq , the d-dimensional vector space over a finite field with q elements (not necessarily prime). Here ∆(E) = {(x1 − y1) 2 + · · ·+ (xd − yd) 2 : x, y ∈ E}. The second listed author and Misha Rudnev ([4]) established the threshold d+1 2 , an...

Abstract Media coverage of migrant and refugee camps often concerns not everyday life in camps, but violence or a camp's outright destruction. These portrayals risk inscribing into public memory as sites danger criminality, vulnerability without agency. What methods engaging with aftermath its representation might enable more complex understandings the reality camps? We engage camp site inscrip...

The authors examined factors related to participation in walking, gardening or yard work, and sports or exercise in 686 community-dwelling adults 60-95 years of age from Wave IV of the population-based Americans' Changing Lives Study. Logistic regression revealed that male gender, being married, and better functional health were associated with greater likelihood of participating in gardening o...

The 6-min walk test (6MWT) is a common component of fitness assessments of older adults; however, differing course configurations might affect 6MWT performance. It is unclear how comparable 2 different configurations are. To determine the comparability of 2 courses, 35 adults >65 years of age completed two 6MWT, once walking around a 20- by 5-yd outdoor rectangle and once on an indoor oval trac...

BACKGROUND Dengue is not well documented in Africa. In Cameroon, data are scarce, but dengue infection has been confirmed in humans. We conducted a study to document risk factors associated with anti-dengue virus Immunoglobulin G seropositivity in humans in three major towns in Cameroon. METHODOLOGY/PRINCIPAL FINDINGS A cross sectional survey was conducted in Douala, Garoua and Yaounde, using...

This study describes the effects of floor system, digital dermatitis (DD) and interdigital dermatitis and heel-horn erosion (IDHE) on locomotion performance in 225 dairy cows of 12 commercial dairy herds. Nine herds were kept in cubicle houses with concrete passageways (either solid, slatted, or grooved concrete) and three herds were kept in straw yards. Animals were at most five times examined...

In a container terminal, containers unloaded from a ship are moved to the yard during the import operation. The export operation is the reverse of the import process. When a ship is served by multiple shore-cranes having both loading and unloading activities at the same time, a yard-machine can process an import container and an export container in one single round-trip. This paper investigates...

On October 15, we met to listen to a presentation by Marques Griffin from ChevronTexaco. He gave an overview of the entire oil production process and gave an idea of what types of positions his company had available. We also had this semester’s officer auction, where bidders could hire an officer for an hour to do such as things as cleaning or yard work. Our volleyball tournament to be held on ...
