A procedure for estimation of sea-surface temperature from remote measurements in the 10 - 13 micrometers spectral region

The feasibility is demonstrated of a procedure for the remote measurement of sea-surface temperature which inherently corrects for the effect of the intervening atmosphere without recourse to climatological data. The procedure relies upon the near-linear differential absorption properties of the infrared window region between 10 and 13 micrometers and requires radiometric measurements in a minimum of two spectral intervals within the infrared window which have a significant difference in absorption coefficient. The procedure was applied to Nimbus 4 infrared interferometer spectrometer (IRIS) data and to Skylab EREP S191 spectrometer data, and it is demonstrated that atmospheric effects on the observed brightness temperature can be reduced to less than 1.0 Kelvin

An Assessment of Canning Practices among Food Preservation Workshop Participants during COVID-19 in Texas

Interest in home food preservation has continued through the COVID-19 pandemic. This study assessed home food preservation practices among individuals attending workshops delivered primarily through distance technology. Two hundred eighty (280) participants completed a survey that assessed methods of food preservation and sources of information and recipes that had been utilized within the previous 12 months. Of those participating, 148 had recently canned food, and 90 of those individuals reported using one or more unsafe methods of food preservation, such as processing vegetables with a boiling water bath canner, open kettle, or oven canning. The internet was the most popular source for food preservation information and recipes, followed by family and friends. One out of four participants who had canned within the previous year reported adapting the recipes. Results suggest a continued and strong need for promoting research-based information and recipes to help those interested in home food preservation gain the skills and knowledge necessary to do it safely

Assessing Master Gardener Practices and Confidence in Responding to Clientele Questions about Home Food Preservation in Texas

Interest in home food preservation has grown, especially among those who grow their own produce. Extension Master Gardeners (EMGs) are trained to teach consumers how to produce fruits, vegetables, and herbs, but little is known about how often they are asked questions about how to preserve them or their ability to answer such questions. This study used an online survey to ask EMGs across Texas about their food preservation practices and the extent to which they are asked questions about home food preservation. We also assessed their perceived confidence in answering those questions using a 5-point Likert scale (1 = not confident at all; 5 = very confident). Most (91%) of the 1875 EMGs who responded reported preserving food using one or more methods. More than half (n = 1034; 55%) had been asked questions about home food preservation, but their level of confidence in answering those questions ranged from a high of 3.1 ± 1.3 (mean ± SD) for freezing fruits and vegetables to a low of 1.6 ± 1.1 for pressure canning low-acid foods. Interest in learning more about home food preservation was high, especially regarding safe practices and recipes, drying herbs, freezing fruits and vegetables, and canning salsa and tomato products. The results suggest that EMG training programs could benefit from including basic information about home food preservation, especially sources of reliable information and recipes

Complex Alternative Splicing of the Smarca2 Gene Suggests the Importance of Smarca2-B Variants

BRM is an ATPase component of the SWI/SNF complex that regulates chromatin remodeling and cell proliferation and is considered a tumor suppressor. In this study we characterized transcripts from the Smarca2 gene that encodes the BRM protein. We found that the human Smarca2 gene (hSmarca2), like its mouse counterpart (mSmarca2), also initiated a short transcript from intron 27 of the long transcript. We name the long and short transcripts as Smarca2-a and Smarca2-b, respectively. Like its human counterpart, mSmarca2-a also underwent alternative splicing at the 54-bp exon 29. The hSmarca2-b had two alternative initiation sites and underwent alternative splicing at three different 3' sites of exon 1 and at exons 2, 3 and/or 5. We identified nine hSmarca2-b mRNA variants that might produce five different proteins. mSmarca2-b also underwent alternative splicing at exon 3 and/or exon 5, besides alternatively retaining part of intron 1 in exon 1. Smarca2-b was expressed more abundantly than Smarca2-a in many cell lines and was more sensitive to serum starvation. Moreover, cyclin D1 also regulated the expression of both Smarca2-a and Smarca2-b in a complex manner. These data suggest that the functions of the Smarca2 gene may be very complex, not just simply inhibiting cell proliferation, and in certain situations may be elicited mainly by expressing the much less known Smarca2-b, not the better studied Smarca2-a and its products BRM proteins
