Effects Of Kaluza-Klein Excited W On Single Top Quark Production At Tevatron

In extra dimension theories if the gauge bosons of the standard model propagate in the bulk of the extra dimensions then they will have Kaluza-Klein excitations that can couple to the standard model fermions. In this paper we study the effects of the first excited Kaluza-Klein mode of the W on single top production at the Tevatron. We find that the cross section for the single top production can be significantly reduced if the mass of the first Kaluza-Klein excited $W \sim 1$ TeV. Hence, a measurement of the single top production cross section smaller than the standard model prediction would not necessarily imply $V_{tb} <1$ or evidence of extra generation(s) of fermions mixed with the third generation.Comment: Text added, Latex, 16 pages, 3 figures, To appear in Phys.

X-rays from accretion shocks in T Tauri stars: The case of BP Tau

We present an XMM-Newton observation of the classical T Tauri star BP Tau. In the XMM-Newton RGS spectrum the O {\sc vii} triplet is clearly detected with a very weak forbidden line indicating high plasma densities and/or a high UV flux environment. At the same time concurrent UV data point to a small hot spot filling factor suggesting an accretion funnel shock as the site of the X-ray and UV emission. Together with the X-ray data on TW Hya these new observations suggest such funnels to be a general feature in classical T Tauri stars.Comment: 4 pages, 4 figures, accepted by A&

Wood fuel for heating (2012)

Increasing energy costs have resulted in resurgence in the use of wood as a fuel for home heating. But heating with wood is not for everyone. Here are a few questions you should ask yourself before investing in a wood-burning unit: Does it make economic sense? ; How do you properly size and install a wood-burning unit? ; Is burning wood suited to your lifestyle? ; Where will the wood come from? ; This guide provides the basic information to help you answer those questions.Revised 3/12/Web

Chipper-shredders (2014)

Disposing of yard waste can be difficult if your municipality bans leaves, grass clippings and other forms of yard waste from landfills. Leaves and other vegetation used to make up a large portion of landfill trash, so these restrictions increase the useful life of a landfill. But they make disposal of yard waste difficult, especially in areas that also ban burning. Composting is a viable alternative for leaves and grass clippings, but it does not work well for brush and small limbs. A chipper-shredder is an alternative that works for all of these yard wastes and offers beneficial side effects as well. (For information on composting, see MU Extension publication G6956, Making and Using Compost.) Chipper-shredders reduce brush and small limbs to a size that is easier to handle and that is suitable for composting or for soil covers, which reduce moisture loss and weed growth and add beauty to a landscaped lawn. Shredding leaves and grass clippings also will reduce the time it takes for composted materials to decay.New 7/93; Reviewed 9/14/300

Forestry assistance for landowners (2015)

Missouri citizens own about 85 percent of the state's 15 million forested acres. Proper care and management of the private forest resource are important to the health of Missouri's economy and environment. Once you as a forestland owner become aware of this valuable resource, you might have questions like 'How can I manage my forest for both wood and wildlife?' or 'Where can I go for help?' Throughout Missouri, the following agencies and organizations can help you find publications, technical advice, educational programs and financial assistance to help you manage your woodlands. The following descriptions will give you an idea of some of the assistance available.New 8/85; Revised 1/15/Web
