We have imaged the H92α (8.3 GHz), H75α (15 GHz), and H166α (1.4 GHz) Radio Recombination Lines (RRLs) from NGC 253 at resolutions of 4.5 pc (0.4) , 2.5 pc (0.2) and 53 pc (4.5) respectively. The H92α line arises from individual compact sources, most of which possess radio continuum counterparts. The line widths range from ∼200 km s for the sources near the radio nucleus to 70-100 km s for the ...

Acetylene, an important petrochemical raw material, is very difficult to store safely under compression because of its highly explosive nature. Here we present a porous metal-organic framework named FJI-H8, with both suitable pore space and rich open metal sites, for efficient storage of acetylene under ambient conditions. Compared with existing reports, FJI-H8 shows a record-high gravimetric a...

High cerebral blood flow velocity (CBFv) and low haemoglobin oxygen saturation (SpO(2)) predict neurological complications in sickle cell anaemia (SCA) but any association is unclear. In a cross-sectional study of 105 Kenyan children, mean CBFv was 120 +/- 34.9 cm/s; 3 had conditional CBFv (170-199 cm/s) but none had abnormal CBFv (>200 cm/s). After adjustment for age and haematocrit, CBFv > or...

PURPOSE This study aimed to determine which factors affect the prognosis of hepatectomy for hepatocellular carcinoma (HCC) larger than 5 cm, including the prognostic difference between tumor sizes from 5-10 cm and larger than 10 cm. METHODS The medical records of 114 patients who underwent hepatectomy for single HCC larger than 5 cm were reviewed and analyzed retrospectively. RESULTS In the...

OBJECTIVES This report presents national estimates of the use of non-Federal short-stay hospitals in the United States during 1997. Numbers and rates of discharges, diagnoses, and procedures are shown by age and sex. Discharges are also shown by geographic region of the hospital. Average lengths of stay are presented for all discharges and for selected diagnostic categories by age and by sex. ...

The partitioning of carbon in intact, mature cotton (Gossypium hirsutum L.) leaves was examined by steady-state (14)CO(2) labeling. Plants were exposed to dark periods of varying lengths, followed by similar illuminated labeling periods. These treatments produced leaves with a range of starch and soluble sugar contents, carbon exchange, and carbon export rates. Export during the illuminated per...

Centimetre-level accurate ionospheric corrections are required for a high accuracy and rapid convergence of Precise Point Positioning (PPP) GNSS positioning solutions. This research aims to evaluate the local/regional delay model using linear interpolation method across Australia. The is assessed as function both different latitudinal regions number spatial density Continuously Operating Refere...

Laparoscopy is now considered the gold standard for treating benign monolateral adrenal lesions. We present the case of a patient affected by Cushing's syndrome due to large bilateral adrenal adenomas (7.5 cm) who underwent simultaneous laparoscopic bilateral adrenalectomy. An anterior, lateral transperitoneal approach was used. Operative time was 200 minutes, and blood loss was 200 mL. No intr...

Analysis of the roles of the short chain fatty acid receptor, free fatty acid 3 receptor (FFA3), has been severely limited by the low potency of its endogenous ligands, the crossover of function of these on the closely related free fatty acid 2 receptor, and a dearth of FFA3-selective synthetic ligands. From a series of hexahydroquinolone-3-carboxamides, we demonstrate that 4-(furan-2-yl)-2-met...

This paper takes a doubting, though friendly, look at the hypotheses of “second generation deciine” and “segmented assimiiation” that have framed the emerging research agenda on the new second generation. We begin with a review of the basic approach, outlining the logic of argument, and specifying the central contentions.We then head toward the past, in search of material that will illuminate b...
