Lacustrine sediment accumulation provides meaningful and diverse long-term records of environmental change. This overview highlights the usefulness of the paleolimnological approach in evaluating the magnitude and direction of human-induced environmental change in lakes and their catchments. Because of the services they provide, freshwater ecosystems have always been significantly affected by h...

background: to evaluate the intermediate-term outcomes of radius shortening as a treatment for kienbock’s disease. materials and methods: in a historical cohort, 16 skeletally mature patients (9 men and 7 women) with kienbock disease, who were treated with radial shortening osteotomy between 2002 and 2012, were reviewed in our study. the mean age of our patients was 30 (range 18-43) years old. ...

This study examined the mechanisms by which income inequality among households with elderly members changed from the mid-1980s to the mid-2000s, focusing on the transformation of household structure and on income sources. The data that I analyze in this paper comes from the Comprehensive Survey of People’s Living Conditions in Japan (CSLCJ) conducted by the Japan Ministry of Health, Labour and ...

the present survey is a correlation study designed to determine extent and type of relation between mid-arm   circumference and weight in order to offer a scale for assumption of weight.   390 healthy, adults who are resident in tehran and between the ages 18-65 were selected from visitors at three   hospital censers at random. input accumulation was carried out by means of a questionnaire and ...

The Pacific North American (PNA) teleconnection has a strong influence on North American climate. Instrumental records and century-scale reconstructions indicate an accelerating tendency towards the positive PNA state since the mid-1850s, but much less is known about long-term PNA variability. Here we reconstruct PNA-like climate variability during the mid- and late Holocene using paired oxygen...

Vowel quality perception in quantity languages is considered to be unrelated to vowel duration since duration is used to realize quantity oppositions. To test the role of microdurational variations in vowel category perception in Estonian listening experiments with synthetic stimuli were carried out, involving five vowel pairs along the close-open axis. The results show that in the case of high...

US cotton growers have adopted Bt and herbicide-resistant varieties rapidly since their introduction in the mid-1990’s. The benefits to growers include higher yields, lower costs and ease of management. In addition, pesticide use has decreased since the introduction of these varieties.

We present multi-epoch 8.4 and 43 GHz Very Long Baseline Array images of the BL Lac object 0735+178. The images confirm the presence of a twisted jet with two sharp apparent bends of 90◦ within two milliarcseconds of the core, resembling a helix in projection. The observed twisted geometry could be the result of precession of the jet inlet, but is more likely produced by pressure gradients in t...

Climate change and forest disturbances are threatening the ability of forested mountain watersheds to provide the clean, reliable, and abundant fresh water necessary to support aquatic ecosystems and a growing human population. Here, we used 76 years of water yield, climate, and field plot vegetation measurements in six unmanaged, reference watersheds in the southern Appalachian Mountains of No...
