a fourth-degree substrate integrated waveguide (siw) crossed coupled band pass filter for wlan band is designed by using a new negative coupling structure. it consists of two u shape microstrip lines on top and bottom planes with via holes at the center of them. this paper investigates the phase characteristics of negative and positive coupling structures and their effects. the design, fabricat...

In this paper, we analyze the fracture patterns observed in wall paintings excavated from Akrotiri, a Bronze-age Aegean city destroyed by earthquakes preceding a volcanic eruption on Thera (modern Santorini) around 1630 BC. We use interactive programs to trace detailed fragment boundaries in images of manually reconstructed wall paintings. Then, we use geometric analysis algorithms to study the...

SUMMARY Leukocyte kinetics were studied in the CDF1 mouse using liquid scintillation and radioautographic technics. Although the latter method provides more detailed information, the former technic is readily adaptable-to experimental manipula tions. The kinetics of mouse leukocytes are different from those in man. Either marrow storage and transit times are different or the generation times of...

Diajrnostic measurement of electric skin conductivity (ESC) called the Ryodoraku system was introduced in mid 1950s by Nakatani. As has been shown by Ziobro et al. in case of infantile cerebral palsy, changes of ESC may provide a valuable electrophysiological parameter for monitoring a therapy. In this study ESC was measured in asthmatic children treated with a bioelectronic unit VEGASELECT. An...

abstract a 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. the cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. the most important physical finding which ...

Kidney transplantation is the preferred therapy for kidney failure. The leading cause of graft loss is chronic allograft nephropathy (CAN). We hypothesize that Interleukin-13 (IL-13), protective against acute kidney graft rejection, is involved in CAN. In mouse kidney allografts, we observe after 2 weeks signs of interstitial inflammation progressing to vasculitis. By 6 weeks, CAN is manifest. ...

The nuclear option at THERA provides an ideal and unique opportunity to investigate the black body limit (BBL) of high energy Deep Inelastic Scattering of highly virtual photons off heavy nuclear targets and thereby probe QCD in a new regime. At high enough energies, whichever hadronic configuration the photon fluctuates into, the interaction at a given impact parameter with the heavy nuclear t...

Colorectal cancer is a common gastrointestinal malignancy in the USA, Europe, and Japan. Most colorectal cancers are thought to arise from preexisting adenomas based on the concept of the adenoma-carcinoma sequence [1]. Chromoendoscopy, using Kudo and Tsuruta’s pit pat‐ tern classification, is an efficient tool for the differential diagnosis of colorectal polyps [2-4]. Re‐ cently, image-enhance...

Radiocarbon (carbon-14) data from the Aegean Bronze Age 1700-1400 B.C. show that the Santorini (Thera) eruption must have occurred in the late 17th century B.C. By using carbon-14 dates from the surrounding region, cultural phases, and Bayesian statistical analysis, we established a chronology for the initial Aegean Late Bronze Age cultural phases (Late Minoan IA, IB, and II). This chronology c...
