Abstract— Over the past years a great deal of work has been done in the field of tooth root resorption but notwithstanding this, understanding of the subject has progressed very little. This paper reviews the subject and suggests ways of minimizing root resorption or perhaps even eliminating it.

This chapter establishes the importance of African American shop workers to Texas railroad hubs such as Marshall, Texas, and explores black responses to the 1922 National Railroad Shopmen’s Strike. Newspaper sources reveal that, while some Texas black and white shopmen cooperated in the 1922 walkout, 216 black shopmen in Marshall dramatically broke ...

, 2008 Nonstationarity is certainly one of the most dominant and enduring characteristics of macroeconomic and financial time series. It therefore seems appropriate that this feature of the data be seriously addressed both in econometric methodology and in empirical practice. However, until recently this has not been the case.

Plant Science![Figure][1] CREDIT: DIANE DIEDERICH/ISTOCK PHOTO Too much salt is as bad for plants as it is for us. For plants, salt stress and drought stress go hand in hand. Some of the more rapid responses to salt stress are signaled through actions of the sucrose nonfermenting ...

This essay examines connections between the academy and Beat poet Gary Snyder, looking specifically at the poet’s relationship to scholarship and the impact it has had on both his writing and teaching. At Reed College, where he met fellow students Lew Welch and Philip Whalen, Snyder wrote a detailed anthropological thesis on Haida mythology, thus ...

AbstractWhen a plant root is reoriented within the gravity field, it responds by initiating a curvature which eventually results in vertical growth. Gravity sensing occurs primarily in the root tip. It may involve amyloplast sedimentation in the columella cells of the root cap, or the detection of forces exerted by the mass of the protoplast on ...

Several types of resorption affect teeth: internal, external, invasive, pressure, and idiopathic resorption. Diagnosis depends on an accurate medical and dental history, and radiographic and clinical examination. Because trauma appears to be a major factor associated with resorption, questions regarding past traumatic events may provide good leads to a
