"Stretching out ahead a frigid wasteland,…so thick a sheet of ice as never locked the Don up in its frozen source"Dante, Inferno, Canto XXXII, "The Ninth Circle"On a wintry early April day, far out in the Lena River basin to the north of Lake Baikal, a file of workers some three thousand strong marched determinedly out of the deforested hills along a road toward a company settlement on the Bodaibo River. Most walked three or four abreast on a road narrowed by the previous night's snow fall, as others trudged along a parallel railroad track a few meters away; within the sparse township, a small figure in the distance waved his arms and shouted but his voice faded in the chill late afternoon air. As the miners proceeded along lengthy stables and stacks of firewood, a uniformed guard hurried forward to persuade them to turn off onto another road. As they rounded the stables, the road curved somewhat bringing them into full view of a substantial building; only a wooden bridge over a small stream and perhaps two hundred meters stood between the workers and their goal. A company of soldiers stood in formation beyond the bridge. The workers' lines faltered uncertainly but people pushed forward from behind.

Abstract It has been observed that the estimation of reference intervals of leukocytes in whole venous blood leads to higher upper reference limits (uRLs) with indirect methods than has been reported in the literature determined by direct approaches. This phenomenon was reinvestigated with a newer, more advanced indirect method, and could be confirmed. Furthermore, a diurnal variation was observed with lower values during the morning and higher values in the late afternoon and at night. This observation can explain why indirect approaches using samples collected during 24 h lead to higher uRLs than direct methods applied on samples collected presumably in the morning.

Feeding Activities

The banded butterflyfish (Chaetodon striatus) from the tropical and subtropical western Atlantic is a territorial, diurnal forager on benthic invertebrates. It is usually seen moving singly or in pairs, a few meters above the sea floor. We studied the foraging activity of C. striatus on rocky reefs in southeastern Brazil. This fish spent about 11 h and 30 min per day on feeding activities, and preferred colonies of non-scleratinian anthozoans over sandy and rocky substrata while foraging. The lowest feeding rates were recorded in the early morning and late afternoon, but we found no further differences between feeding rates throughout the day. We also found no differences between the feeding rates of paired and single individuals.

Abstract Hourly station rain gauge data are employed to study the seasonal variation of the diurnal cycle of rainfall in southern contiguous China. The results show a robust seasonal variation of the rainfall diurnal cycle, which is dependent both on region and duration. Difference in the diurnal cycle of rainfall is found in the following two neighboring regions: southwestern China (region A) and southeastern contiguous China (region B). The diurnal cycle of annual mean precipitation in region A tends to reach the maximum in either midnight or early morning, while precipitation in region B has a late-afternoon peak. In contrast with the weak seasonal variation of the diurnal phases of precipitation in region A, the rainfall peak in region B shifts sharply from late afternoon in warm seasons to early morning in cold seasons. Rainfall events in south China are classified into short- (1–3 h) and long-duration (more than 6 h) events. Short-duration precipitation in both regions reaches the maximum in late afternoon in warm seasons and peaks in either midnight or early morning in cold seasons, but the late-afternoon peak in region B exists during February–October, while that in region A only exists during May–September. More distinct differences between regions A and B are found in the long-duration rainfall events. The long-duration events in region A show dominant midnight or early morning peaks in all seasons. But in region B, the late-afternoon peak exists during July–September. Possible reasons for the difference in the diurnal cycle of rainfall between the two regions are discussed. The different cloud radiative forcing over regions A and B might contribute to this difference.

Objective. This study evaluated the effects on behavior and sleep of methylphenidate (MPH) administered at 4 PM to children with attention-deficit hyperactivity disorder (ADHD). Methodology. Twelve children admitted to a child psychiatric inpatient service with ADHD participated in a double-blind, crossover study in which they received a 4 PM dose of either 15 mg of MPH, 10 mg of MPH, or a placebo in random order for 12 consecutive days. Ratings of behavior, including ADHD symptoms, pertaining to the period from dose administration until sleep onset, were supplied nightly by hospital staff. Sleep latency and sleep adequacy were also assessed for each night. Results. MPH resulted in markedly improved behavioral control compared with placebo; there was no difference between 15-mg and 10-mg MPH doses. MPH did not alter sleep latencies observed with the placebo. Children were more often rated as less tired on awakening after nights that they received 10 mg of MPH compared with 15 mg of MPH and the placebo. Weight loss was apparent among 83% of the patients, but dinner intake did not vary with third-dose condition. Conclusions. Morning and noon administration of stimulants to children with ADHD is a near-universal practice, but many clinicians avoid a third, late-afternoon administration for fear of inducing insomnia. This study's findings show that children with ADHD derive substantial symptom reduction from MPH administered in late afternoon, with no untoward effects on sleep. Therefore, three-times-a-day dosing should be considered for those children exhibiting ADHD symptoms in the evening. Adverse effects on sleep latency were not apparent in the sample overall. Nonetheless, monitoring for possible aggravation of sleep problems and weight loss remains sound treatment practice.

We analyzed the thermal ecology and activity patterns of the lizard community from the Restinga of Jurubatiba, Rio de Janeiro, Brazil. The broadest activity was that of Tropidurus torquatus, a sit-and-wait forager, while the active foraging teiid Cnemidophorus littoralis had the shortest activity. The nocturnal gekkonid Hemidactylus mabouia was found active during the day only during early morning and late afternoon, when environmental temperatures are low. Body temperature was highest for Cnemidophorus littoralis and lowest for the two Mabuya species. The patterns found here are discussed and compared to those of congeneric species in other habitats in Brazil.

In a 42,750-ha survey area in subtropical Queensland, rabbit warrens are confined mainly to sandy soils. Within these favoured areas the population is distributed unevenly, and there is further selection for preferred habitats. Detailed studies on a 246-ha area of sandhill showed that the open woodland and grassy open woodland associations contain most warrens per unit area, and also the largest warrens. The quality of habitat for rabbits appears to be determined by availability of food, type of soil, and vegetation cover providing protection from predators. In some vegetation associations, use of burrows varies only slightly, in others there are significant changes. There is a significant correlation between the estimated numbers of rabbits in the population, the total number of rabbits seen on spotlight transect counts in the evening, the numbers of rabbits seen on warrens during late afternoon watches, and the total number of active burrow entrances present in the study area. A list of plant species present and a description of the 23 vegetation associations in the study area is presented.

Abstract. Marine stratocumulus (Sc) clouds play an essential role in the earth radiation budget. Here, we compare liquid water path (LWP), optical thickness (COT), and effective radius (CER) retrievals from two years of collocated Spinning Enhanced Visible and InfraRed Imager (SEVIRI), MODerate resolution Imaging Spectroradiometer (MODIS), and Tropical Rainfall Measuring Mission Microwave Imager (TMI) observations, estimate the effect of biomass burning smoke on passive imager retrievals, as well as evaluate the diurnal cycle of South Atlantic marine Sc clouds. The effect of absorbing aerosols from biomass burning on the retrievals was investigated using aerosol index (AI) obtained from the Ozone Monitoring Instrument (OMI). SEVIRI and MODIS LWPs were found to decrease with increasing AI relative to TMI LWP, consistent with well-known negative visible/near-infrared retrieval biases in COT and CER. In the aerosol-affected months of July–August–September, SEVIRI LWP – based on the 1.6-µm CER – was biased low by 14 g m−2 (~ 16 %) compared to TMI in overcast scenes, while MODIS LWP showed a smaller low bias of 4 g m−2 (~ 5 %) for the 1.6-µm channel and a high bias of 8 g m−2 (~ 10 %) for the 3.7-µm channel compared to TMI. Neglecting aerosol-affected pixels reduced the mean SEVIRI-TMI LWP bias considerably. On a two-year data base, SEVIRI LWP had a correlation with TMI and MODIS LWP of about 0.86 and 0.94, respectively, and biases of only 4–8 g m−2 (5–10 %) for overcast cases. The SEVIRI LWP diurnal cycle was in good overall agreement with TMI except in the aerosol-affected months. Both TMI and SEVIRI LWP decreased from morning to late afternoon, after which a slight increase was observed. Terra and Aqua MODIS mean LWPs also suggested a similar diurnal variation. The relative amplitude of the two-year mean and seasonal mean LWP diurnal cycle varied between 35–40 % from morning to late afternoon for overcast cases. The diurnal variation in SEVIRI LWP was mainly due to changes in COT, while CER showed only little diurnal variability.
