A binding site for the antibiotic GE81112 in the ribosomal mRNA channel.

The initiation phase is the rate-limiting step of protein synthesis (translation) and is finely regulated, making it an important drug target. In bacteria, initiation is guided by three initiation factors and involves positioning the start site on the messenger RNA within the P-site on the small ribosomal subunit (30S), where it is decoded by the initiator tRNA. This process can be efficiently inhibited by GE81112, a natural hydrophilic, noncyclic, nonribosomal tetrapeptide.

Beyond men and women: a critical perspective on gender and disaster.

Consideration of gender in the disaster sphere has centred almost exclusively on the vulnerability and capacities of women. This trend stems from a polarised Western understanding of gender as a binary concept of man-woman. Such an approach also mirrors the dominant framing of disasters and disaster risk reduction (DRR), emphasising Western standards and practices to the detriment of local, non-Western identities and experiences.

Comparison of the predation rate of freshwater cyclopoid copepod species on larvae of the mosquito Culex pipiens.

The predation rates of six copepod species: Acanthocyclops robustus G.O. Sars, Eucyclops neumani Pesta, Macrocyclops albidus Jurine, Mesocyclops longisetus Thibaud, Metacyclops grandis Kiefer and Metacyclops mendocinus Wierzejski (Copepoda: Cyclopidae) on mosquito larvae, Culex pipiens Linnaeus (Diptera: Culicidae) were assessed.

[The school child carrying heavy burdens].

In 163 Viennese pupils in standard 1 to 8, the weight of the schoolbag, the bodyweight and the ratio of these two parameters were examined in order to describe the amount of burden carried by those children. The results were: 1. The weight of the schoolbag war 4.
