Rotationally resolved collisional transfer rates in OH

Fluorescence lidar measurements of the hydroxyl radical require detailed information concerning collision induced processes in order to deduce the radical number density from a lidar return. The Goddard SFC OH lidar currently utilizes a broadband detector which precludes the necessity of fully understanding collisional redistribution of rotational energy within the excited state. Numerous advantages result however from the inclusion of a detector with a bandpass only slightly larger that the Doppler width of a rotational line. This however places more stringent requirements on the spectroscopy. Measurements were accordingly made of rotationally resolved quenching rates for collisions with O2, N2, and H2O. Rotational transfer rates were also measured for the same colliders. Quenching rates were measured using a Nd-YAG pumped Rh6G dye laser doubled into the UV. The OH lifetimes were measured as a function of pressure of quenching gas at total pressures of between 50 and 250 microns. Rotational transfer rates were measured by recording the emission spectrum on an intensified diode array and integrating over 10.000 laser shots

Alfalfa for Beef Cattle

Alfalfa is sometimes said to be too good for beef cattle. Although it\u27s nutritional value may sometimes exceed beef cows\u27 needs, to dismiss it\u27s potential for beef cattle would be a mistake. Alfalfa can be useful as a harvested feed or as a grazing crop

Animal Welfare--Animal Rights: Protecting Animals or a Threat to U.S. Food Production and Our Way of Life?

Cattle producers are accustomed to dealing with many forms of adversity. Adversity generally comes in the form of blizzards, droughts, floods and economic conditions but now we must deal with animal activists who have their own opinions of what we can and cannot do as it relates to animal welfare and animal rights

Grazing Alfalfa — An Overview

Alfalfa is the most important forage legume grown in the United States. Grown over a wide range of soil and climatic conditions it has the highest yield potential and feeding value of all perennial forage legumes. This versatile crop can be used for hay, pasture, silage, green-chop, pellets, cubes and soil improvement. Because of its many merits, especially yield, quality and versatility, it can be used successfully in many animal feeding programs. Grazing alfalfa has not been practiced to any great extent in the U.S., but has been done extensively in other countries. Research and producer experience has shown excellent gains per animal and per acre without shortening the alfalfa stand\u27s life expectancy

Analysis of Traveler Characteristics by Mode Choice in HOT Corridors

This research examined travelers who have a vast array of travel options, including some rather unique ones: HOV3+ in an HOV lane, HOV2+ in an HOV lane off-peak, HOV2 plus a $2.00 toll in an HOV lane during the peak, and casual carpooling (slugging). Travelers using all these modes were surveyed in 2003, and significant differences between the groups of travelers were observed, providing some understanding of travel behavior when faced with these travel options. In the study, particular effort was spent on examining the characteristics of travelers who choose to travel as HOV2 carpools during peak periods and pay a$2.00 toll. This group of travelers was found to contain significantly more well-educated females with high household incomes on school related trips. The proximity of private schools near the terminus of the HOV lane probably contributed significantly to this result. Due to the array of mode choices available to these travelers, surveying all these groups was challenging and, therefore, the methodology employed in survey development and administration is also detailed in this paper

Maximizing Alfalfa Hay in Beef Feeding Programs

Beef cattle comprise the largest group of forage and hay users in Kentucky. Because of their ability to utilize large amounts of low quality roughage, they are sometimes relegated to that role exclusively. There are many instances in beef production when alfalfa hay can be utilized because of its high protein content. The value of alfalfa hay in a beef operation can be estimated by the protein and energy that it furnishes

Adulting 101: Know Your Audience

During the winter of 2017, I began to see a common topic on library programming group threads centering around ideas such as teaching basic life skills to young and new adults that may not have been taught at home or school. Around the same time, Clara Piazzola, the library’s young adult assistant, came to me to share an idea that was buzzing around her library school discussion boards. She told me about a program idea that would teach young people necessary skills to help them survive in the grownup world. Talk about a coincidence! I gave her the go ahead, and she began planning. Clara came up with the name, Adulting 101, and a six-month program outline. Planning each session, we chose to invite local speakers for a few of the topics that warranted professional facilitators. Flyers were displayed in the library and mailed to local bulletin boards and radio stations. Adulting 101 was posted to the library website, social media, and electronic calendars. We reserved the room, bought snacks, and were ready to launch. The event post on our library’s Facebook page started a ripple effect that took us by surprise. We had Facebook likes and shares from tens of thousands of viewers. People were emailing and phoning our City Administrator, Library Director, and the library for more information. The local television station saw the post, called for an interview, and covered the first program. There were radio interviews. We had electronic inquiries and phone calls from across the country and then some. The American Library Association’s Programming Librarian asked for an article (Lucas, 2017). Adulting 101 was even mentioned on the morning talk show LiveKellyandRyan (Adulting 101 for Millenials [sic], 2017)

Grazing Alfalfa — State Perspective

Alfalfa has been grown in Kentucky for many years, but in the last decade, its acreage has increased dramatically- from 208,000 in 1978 to 350,000 in 1981 (Ky. Agri. Statistics Service). Alfalfa is generally thought of as a hay crop but the practice of grazing alfalfa has received considerable attention recently. Much of this interest was generated by Graze-More-Beef demonstrations which have been conducted in the state. Demonstrations in which alfalfa was grazed averaged 791 pounds per acre during 1986-1988. Alfalfa\u27s ability to withstand dry weather and its excellent nutritional qualities make it an attractive grazing alternative to fescue - especially during the mid-summer period. Grazing also requires less equipment than expensive conventional harvesting of hay. But ... it also requires intensive management for optimum results

Do the Outburst Properties of M31N 2008-12a Depend on the Time Since the Previous Eruption?

Photometric observations spanning the UV to the near IR during the nine most recent eruptions (2014-2022) of the extragalactic nova M31N 2008-12a are presented and analyzed in order to explore whether the lightcurve properties for a given eruption, specifically the peak magnitudes and fade rates, are correlated with the time interval since the previous eruption. No significant correlation between the pre-eruption interval and the rate of decline was found, however it appears that the brightness at the peak of an outburst may be positively correlated with the time interval since the previous eruption.Comment: 5 pages, 1 figure, 1 table (data behind the figure); accepted for publication in Research Notes of the AA
