In the millimeter-wave band, the series-fed array antenna is facing a problem of large transmission loss and narrow bandwidth by using a high-permittivity and large-loss-tangent material. In this paper, an air region is inserted in the half of the height in the LTCC waveguide of εr =6.6 and tanδ =0.013 to reduce the transmission loss. The reduction of the equivalent dielectric constant by the a...

Copy right Idea Grou p Inc . Copy right Idea Grou p Inc . Internet online sales totaled $7.8 billion for 1998, with the average online shopper spending $629 (Fasig, 1999). During the 1999 holiday season, online sales were reportedly double that of 1998 at many “e-tailers” (although final statistics had not been published as this chapter went to press). As Web-based consumer sales grow, so does ...

T HE industrial sector has long been regarded as the stepchild of marketing in terms of the amount of research effort devoted to its problems. There are, however, indications that the situation may be changing. Research on industriallorganizational buying behavior is growing, and a considerable body of empirical knowledge about processes surrounding the innovation and diffusion of industrial te...

The distribution of quality characteristic of a product is usually assumed to be known. In some situation, the quality characteristic of a product cannot be measured directly. It needs to be measured by controlling another factor. Wen and Mergen (1999) presented a method for determining the optimum process mean in order to minimize the expected total loss of a product. However, they have not co...

The loss caused by the so-called minor diseases is not usually considered of sufficient importance to warrant the adoption of control measures such as those used in combating major diseases; nevertheless it has frequently been asserted that if the total loss due to the activities of all minor diseases could be estimated it would probably amount to more than is imagined. Further, a disease which...

1. Moderately overweight, premenopausal women were assessed for bone mineral density of the total body, lumbar spine and proximal femur before and after 6 months of modest dietary restriction (minimum 4800 kJ/day). The aim was to evaluate the effect of loss of body mass on bone mineral density. 2. Dietary assessment included two analyses of 3 day weighed food intakes, one before and the other a...

"What about the gym?" was the big question at this week's presidential press conference, as all other school matters were put aside. The crowd filed from the Patroon lounge to the Assembly Hall and finally to the Ballroom. The number of persons attending seemed to increase with every move and soon totaled 600 or 700. Dr. Clifton Thome, VicePresident of Student Affairs, held the press conference...

UNLABELLED A variety of mechanisms have been proposed to explain the malnutrition and body mass loss in UC patients. The aim of the study trial was a nutritional state assessment of 347 UC patients, admitted for surgical treatment, and the evaluation of the impact of this state on the postoperative course in this group of patients. MATERIAL AND METHODS We referred the results of nutritional s...

Introduction: Laparoscopic gastric plication (LGP) is a relatively new restrictive bariatric procedure that emerged to avoid the problems and to reduce the cost of laparoscopic sleeve gastrectomy. In this study we present the initial short-term outcome of LGP and its effect on gastric emptying and compare it with the results of laparoscopic sleeve gastrectomy (LSG). <stro...

STUDY OBJECTIVES To determine the relationship between weight-loss and pulmonary function indexes, focusing on forced expiratory flows (ie, FEV(1), forced expiratory flow at 50% of vital capacity [FEF(50)], forced expiratory flow at 75% of vital capacity, and forced expiratory flow at 25 to 75% of vital capacity [FEF(25--75)]). Specifically, to determine the effect of losses in total and segmen...
