Prolonged cultivation of embryos to the blastocyst stage has become a routine practice in the human in vitro fertilization program (IVF) since 1999, when the first commercial sequential media were developed. The culture systems have been improved many times and today most of the blastocyst culture media enable the embryos to reach the blastocyst stage in more than 50% of cases (Gardner et al., ...

Tropical forests are under unprecedented pressure for conversion to pastoral and agricultural land or to plantations (including for biofuel production) and from the supply and extraction of forest goods and services, including timber and bushmeat (Kant 2004, Gardner et al. 2009). To preserve them, much effort has gone into setting up and managing a network of protected areas because, for variou...

In this paper, based on the known first integral method, we try to seek the traveling wave solutions of several nonlinear evolution equations. As a result, some exact travelig wave solutions and solitary solutions for Whitham-Broer-Kaup (WBK) equations, Gardner equation, Boussinesq-Burgers equations, nonlinear schrodinger equation and mKDV equation are established successfully. Key–Words: First...

The adiabatic parameter dynamics of solitons due to Gardner’s equation is obtained, in presence of the perturbation terms, by the aid of soliton perturbation theory. In addition, the integrals of motion are evaluated as well as the variation of the velocity is obtained due to these perturbation terms. Mathematics Subject Classification: 35Q51, 35Q53, 37K10 PACS Codes: 02.30.Jr, 02.30.Ik 788 A. ...

In this paper, a new technique using tensor product is presented in order to provide exact solutions some certain fractional differential equations. Particularly, the well-known third Gardner’s equation, which also known contexts as KdV-mKdV, of type. This type equations plays an important role modeling many symmetric and asymmetric problems. Moreover, existence atomic solution for second has b...

Gardner’s syndrome is characterized by a triad of intestinal polyposis, which ultimately become malignant, soft-tissue neoplasms such as desmoid tumors and fibromas, and osteomas, particularly of the skull and facial bones. A case report of bilateral osteomas of the coronoid process resulting in limited incisal opening in a 12-year-old girl and review of the pertinent literature is presented. G...

Multiexponential transient signals are particularly important due to their occurrences in many natural phenomena and human applications. For instance, it is important in the study of nuclear magnetic resonance (NMR) in medical diagnosis (Cohn-Sfetcu et al., 1975)), relaxation kinetics of cooperative conformational changes in biopolymers (Provencher, 1976), solving system identification problems...

To the Editor—The paper by Gardner et al [1] on the spectrum of engagement in human immunodeficiency virus (HIV) care provides an important heuristic for understanding the parameters and outcomes for a successful test-and-treat strategy to reduce HIV transmission. The spectrum begins with persons infected with HIV (unaware and aware) and progresses through diagnosed, linked to care, retained in...

Pregermination treatments applied to seed of Gardner saltbush, [ALriplexgar&cri(Moq.) D. Dietr.] were evahtated for alleviation of seed dormancy. Treatments selected simulated conditions the seed might be exposed to in its natural environment, including dry afterripening, scarification, leaching, and cold stratification. Germination response to individual treatments was equal to or higher than ...
