OBJECTIVE To observe and compare the Tympanic Temperature (TT) readings with the Oral Mercury Thermometer (OMT) in an OPD setting. STUDY DESIGN Observational comparative study. PLACE AND DURATION OF STUDY The Outpatient Department, Shifa International Hospital, Islamabad, from June to September 2008. METHODOLOGY By consecutive sampling, 2000 OPD patients were included in the study. Both t...

Arrays of semimetallic Bi nanowires have been successfully fabricated by electrodeposition. Each nanowire consists of elongated Bi grains along the wire direction. Very large positive magnetoresistance of 300% at low temperatures and 70% at room temperature with quasilinear field dependence has been observed. These features are desirable for wide-range field sensing applications. © 1998 America...

The viability of Ochlerotatus albifasciatus (Macquart) eggs stored at room temperature and at 5oC was studied over 31 months. After 12, 18 and 31 months of storage, eggs were acclimatized at 22oC for ten days, and then inundated twice every seven days. The effect of the storage period on the percentage of hatching was analyzed by one way ANOVA. Differences on the hatching response between the f...

Electronic transport properties of bismuth nanocontacts are analyzed using a low temperature scanning tunneling microscope. The subquantum steps observed in the conductance versus elongation curves give evidence of atomic rearrangements in the contact. The quantum nature of the conductance reveals itself through peaks in the conductance histograms. The shape of the curves at 77 K is described b...

Colon capsule endoscopy utilizing PillCam COLON 2 capsule allows for visualization potentially of the entire colon and is currently approved for patients who cannot withstand the rigors of traditional optical colonoscopy (OC) and associated sedation as well as those that had an OC that was incomplete for technical reasons other than a poor preparation. We will then describe the prior experience...

Temperature has a strong influence on biological rates, including the contractile rate properties of muscle and thereby the velocity, acceleration and power of muscle-powered movements. We hypothesized that the dynamics of movements powered by elastic recoil have a lower thermal dependence than muscle-powered movements. We examined the prey capture behavior of toads (Bufo terrestris) using high...

abstract objective fever and neutropenia are a common complication of chemotherapy in cancer. it is usually managed by hospitalization and empiric administration of antibiotics. use of fluroquinolones is limited because of joint/cartilage toxicity. this study attempted to compare the efficacy of oral ciprofloxacin with intravenous ceftazidim in low risk febrile neutropenic lymphocytic leukemia....

We have fabricated a high mobility device, composed of a monolayer graphene flake sandwiched between two sheets of hexagonal boron nitride. Conductance fluctuations as functions of a back gate voltage and magnetic field were obtained to check for ergodicity. Non-linear dynamics concepts were used to study the nature of these fluctuations. The distribution of eigenvalues was estimated from the c...

We have performed a comprehensive study into low temperature ( 500 °C) internal gettering in multicrystalline silicon (mc-Si). Two groups of as-grown mc-Si wafers from different ingot height positions were subjected to the same thermal treatments with surface passivation by either silicon nitride (SiNx:H) or a temporary iodine-ethanol (I-E) chemical solution . With either passivation scheme, l...

OBJECTIVE Dental materials are often made at room temperature, whereas clinically they are made in the mouth. This study evaluated the effects of temperature on the degree of conversion (DC) and Knoop microhardness (KHN). MATERIALS AND METHODS Two types of resin-based composites (RBCs) were light-cured using a light-emitting diode (LED) light-curing unit. The resin specimens were centered on ...
