Rapid Prototyping and 3‐D Printing of Experimental Equipment in Soil Science Research
Authors: Rangel David P. , Superak Claire , Bielschowsky Mayra , Farris Katie , Falconer Ruth E. , Baveye Philippe C.
Published: November 2012

Until recently, the custom manufacture of equipment for laboratory or field experiments in soil science required appreciable know‐how, and was extremely time‐consuming. Technological advances in rapid prototyping and “3‐D printing” in the last decade afford significant, and as yet untapped, opportunities to manufacture equipment in a very different way. In the present note, we demonstrate with two concrete examples that 3‐D printing is not only a very effective and versatile technique to produce laboratory or field equipment. It also alleviates some of the restrictive technical constraints imposed by lathes and molding processes used traditionally, and it permits a much more efficient sharing of information among researchers. Given the tremendous advances in 3‐D printing unfolding at the moment, it is anticipated that this technology will revolutionize the way we design, and especially replicate, experiments in soil science.
Letrozole: Advancing Hormone Therapy in Breast Cancer
Authors: Lee Rebecca J , Armstrong Anne C , Wardley Andrew M
Published: November 2012

Letrozole is a type 2 aromatase inhibitor, which reduces availability of estrogen in postmenopausal women, thereby decreasing its ability to stimulate breast cancer cells. Phase III trials in both the advanced and early breast cancer setting have shown an improvement in disease-free survival compared with other compounds, including tamoxifen. Letrozole is well-tolerated, with the main adverse effects reported as hot flushes, arthritis, arthralgia and myalgia, and a trend towards increased risk of fracture.
Geographic Differences in Fractures among Women
Authors: Litwic Anna , Edwards Mark , Cooper Cyrus , Dennison Elaine
Published: November 2012

Osteoporotic fracture is associated with considerable morbidity and mortality in women throughout the world. However, significant variation in hip fracture rates among women from different nations has been observed and is likely to represent a combination of real and apparent differences due to ascertainment bias. Higher rates are observed in Caucasian women, with lowest rates observed in black women and intermediate rates among Asian women. These differences are likely to represent a combination of genetic and environmental differences; for example, among European women, the highest fracture rates are observed in Scandinavian women where vitamin D insufficiency is common. In all groups, an increase in absolute fracture numbers is anticipated due to demographic changes.
Biological Aspects of Postpartum Depression
Authors: Skalkidou Alkistis , Hellgren Charlotte , Comasco Erika , Sylvén Sara , Poromaa Inger Sundström
Published: November 2012

In comparison with the vast epidemiological literature on postpartum depression (PPD), relatively few studies have examined the biological aspects of the disorder. However, research into the biological mechanisms of PPD is a challenging task, as normal pregnancy and the postpartum period cause adaptive endocrine changes, which would otherwise be considered pathological in nonpregnant women. This review focuses on the adaptive changes of childbearing and nursing, which ultimately may put women at increased risk of PPD. In light of the normal physiology, the authors also attempt to describe the current evidence of the biological changes associated with the development of depression in the postpartum period, including ovarian steroids, the hypothalamic–pituitary–adrenal axis, the serotonergic neurotransmitter system, the thyroid system and inflammatory markers. In addition, current knowledge on candidate genes associated with PPD is reviewed.
Chemoprevention of Breast Cancer
Authors: Files Julia A , Stan Daniela L , Allen Summer V , Pruthi Sandhya
Published: November 2012

The development of pharmacologic agents for the prevention of breast cancer is a significant milestone in medical and laboratory research. Despite these advances, the endorsement of preventive options has become challenging and complex, as physicians are expected to counsel and tailor their recommendations using a personalized approach taking into account medical comorbidities, degree of risk and patient preferences. This article provides a comprehensive overview of the major breast cancer prevention trials, review of the pharmacologic options available for breast cancer prevention, and strategies for integrating chemoprevention of breast cancer in high-risk women into clinical practice.
Hypercyclic and chaotic integrated C-cosine functions
Authors: Kostic Marko
Published: November 2012

The main purpose of the paper is to display the main structural properties of
hypercyclic and chaotic integrated C-cosine functions. The notions of
hypercyclicity, mixing and chaoticity of an ?-times integrated C-cosine
function (??0) are defined by using distributional techniques. We provide
several examples which justify our abstract theoretical approach.
The structure of ν-isologic pairs of groups
Authors: Heidarian Shahram , Gholami Ahmad , Abadi Mohammad
Published: November 2012

In [2], the first two authors generalized the concept of n-isoclinism to the
class of all pairs of groups. In this paper, we extend that notion to
?-isologism and study the details of this notion. In addition, it is shown
that every pair of groups is ?-isologic with a quotient irreducible pair of
groups. Finally, as an application, we drive some inequalities for the
Baer-invariant of a pair of groups.
Quantum integrals and the affineness criterion for quantum Yetter-Drinfeld π-modules
Authors: Quan-Guo Chen , Shuan-Hong Wang
Published: November 2012

In the paper, the quantum integrals associated to quantum Yetter-Drinfeld
?-modules are defined. We shall prove the following affineness criterion: if
there exists ? = {?? : H? ? Hom(H?-1, A)} ? ? ? a total quantum integral and
the canonical map ? : A?B A ? ???? H? ? A, ?(a?B b)= ???? S?-1
??(b[1,?-1?-1?])b[0,0]<-1,?> ? ab[0,0]<0,0> is subjective. Then the
induction functor -?B A : UB ? H YD?A is an equivalence of categories. The
affineness criterion proven by Menini and Militaru is recovered as special
cases.
Polynomials of the Laguerre type
Authors: Djordjevic Gospava
Published: November 2012

In this noteweshall study a class of polynomials {f c,r n,m(x)}, where c is
some real number, r ? N?{0}, m ? N. These polynomials are defined by the
generating function. Also, for these polynomials we find an explicit
representation in the form of the hypergeometric function; some identities
of the convolution type are presented; some special cases are shown. The
special cases of these polynomials are: Panda?s polynomials [2], [4]; the
generalized Laguerre polynomials [1], [6]; the Celine Fasenmyer polynomials
[3].
A regularized method for two dimensional nonlinear heat equation backward in time
Authors: Tuan Huy , Trong Duc , Quan Hoang
Published: November 2012

In this paper, a non-local boundary value problem method for solving 2-D
nonlinear heat equation backward in time is given. Some error estimates
between the exact solution and its regularization approximation are provided
and numerical examples show that the method works effectively.

boundedness and compactness of the integral operator (Cn ?,1 f )(z) = ?z 0 f

Structure of shock wave for a viscous combustion model
Authors: Razania Abdolrahman
Published: November 2012

In this article, the existence of weak and strong detonation waves for a
viscous combustion model is proved. In order to prove the existence of this
kind of waves, it is necessary to consider a 3-dimensional system of
ordinary differential equations and prove the existence of heteroclinic
orbits of it. In order to prove this, topological arguments are mainly
tools.
