We complete the Wilf classification of signed patterns of length 5 for both signed permutations and signed involutions. New general equivalences of patterns are given which prove Jaggard’s conjectures concerning involutions in the symmetric group avoiding certain patterns of length 5 and 6. In this way, we also complete the Wilf classification of S5, S6, and S7 for involutions.

The chloroplast rps12 gene encoding ribosomal protein S12 from wild-type as well as from streptomycin-resistant and -dependent mutants of Chlamydomonas reinhardtii was cloned and sequenced. At least six mRNA transcripts ranging in size from 800 to 4800 nucleotides were found to contain the rps12 coding sequence. As in Escherichia coli and Euglena, the C. reinhardtii rps12 gene is continuous, in...

Genetic studies with Burkholderia cepacia complex isolates are hampered by the limited availability of cloning vectors and by the inherent resistance of these isolates to the most common antibiotics used for genetic selection. Also, some of the promoters widely employed for gene expression in Escherichia coli are inefficient in B. cepacia. In this study, we have utilized the backbone of the vec...

In order to satisfy the needs of pig breeding, an intelligent feeding control system based on S7 1200PLC is designed in this paper. The design scheme selects Siemens S7-1200 PLC as main controller and MCGS TPC7062TI touch screen man-machine interface. article has carried electrical design, including I/O address allocation, circuit so on, written program debugging mode operation mode, finally in...

This Technical Bulletin reviews the indications for gonadotropin treatment in anovulatory women; outlines the recommended pretreatment evaluation, treatment regimens, and monitoring; describes the alternatives and adjuncts to treatment with gonadotropins; and summarizes the complications of gonadotropin treatment.

BACKGROUND & OBJECTIVE Activation of T cells is mediated through two critical signals provided by activated macrophages. The first signal is triggered when T cell receptor (TCR) binds to the major histocompatibility antigen (MHC/Ag) complex. The second signal is the interaction of co-stimulatory molecules with their respective ligands on T cells for their activation and proliferation. We undert...
