This paper presents 186 groups compressive strength tests data of concrete with manufactured sand (MSC) in different curing age and 262 groups compressive strength tests data of MSC at 28 days collected from authors' experiments and other researches in China. Further interpretation and discussion were described in this issues.

Research on the response of livestock grin to stocking rate tends to cluster into 5 “invisible colleges”, represented by 5 citation networks which only occasionally intersect. Each college is built around a paradigm of the stocking rate-gain response as developed in 2 key papers sharing 1 or more authors. Researchers tend to cite the paradigm developed by authors in their field of research or i...

We analyze optimal production and pricing strategies in the single period (newsvendor) dual sourcing problem that entails local and offshore suppliers. The local supplier is used reactively as an emergency source following the realization of random demand. A multiplicative demand model is employed. We show that dual sourcing flexibility may decrease optimal price when emergency supply cost is s...

Pond carrying capacity is largely determined by management practices. Earlier work on semiintensive culture of Nile tilapia (Oreochromis niloticus) using manure or inorganic fertilizers indicated that carrying capacity might reach 2,000 to 3,000 kg/ha (Diana et al. 1991a, b; Knud-Hansen et al. 1991). As stocking density is increased in fertilized ponds, carrying capacity remains largely the sam...

In this paper, a delayed ratio-dependent Holling-III predator-prey system with stage-structured and impulsive stocking on predator and continuous harvesting on prey is considered. We obtain sufficient conditions of the global attractivity of prey-extinction periodic solution and the permanence of the system. These results show that the behavior of impulsive stocking on predator plays an importa...

Compressive sensing provides a new framework for simultaneous sampling and compression of signals. According to compressive sensing theory one can recover compressible signals and images from far fewer samples or measurements that traditional methods use. Applying compressive sensing theory for holography comes natural since three-dimensional (3D) data is typically very redundant, thus it is al...

OBJECTIVES/HYPOTHESIS Compressive symptoms are common in thyroid disease, but few studies have focused on the presence, associated factors, and etiology of compressive symptoms. STUDY DESIGN Retrospective review. METHODS Patients who underwent thyroidectomy from 2005 through 2009 were reviewed. The data included demographics, indication for surgery, compressive symptoms, complications, diag...

A study was conducted to appraise the effect of different stocking densities on three male morphotypes named blue claw (BC), orange claw (OC) and small male (SM) at harvest  in all-male culture and to assess the growth performance of  BC, OC and SM in each isolated culture. Trials involving three stocking densities of all-male prawn viz., 20, 30 and 40 juvenile m-2 were carried out in...

An experiment on the polyculture of carps with high valued small indigenous fish species (SIS) pabda (Ompok pabda) and gulsha (Mystus cavasius) was carried out in six months culture period to evaluate the production performance of carp with small indigenous fish pabda (Ompok pabda) and gulsha (Mystus cavasius) in the on-farm condition. Three stocking densities of pabda and gulsha were tested, k...

In this study, the effects of oxygen supplementation in different stocking densities of rainbow trout (Oncorhynchus mykiss) on the specific growth rates (SGR), feed conversion ratios (FCR) and survival rates were investigated in a commercial-scale culture system. High density cultures were maintained in a total of nine (12 m3) flow-through systems supplemented with O2. Initial stocking rates fo...
