In Thailand, ceramic jars (135-200 liters) covered by aluminum lids commonly are used to store water for household use. In laboratory cages, gravid female Aedes aegypti (L.) were able to enter and oviposit in a covered water jar. Although the aluminum lid was not a complete barrier to gravid females, it reduced the number of eggs oviposited by 77%. A vertically oriented foam rubber ring which w...

Section 1 A 60-year-old previously healthy man awoke with right arm pain and numbness. Opioids resulted in modest pain relief, but over the following weeks, the pain worsened. He began dropping things and had more difficulty writing, buttoning clothing, and opening jars. Cervical MRI demonstrated mild central canal stenosis and moderate foraminal stenosis at multiple levels, worse on the left. ...

An octopus can be a canny customer – by shortening, bending, elongating and twisting its highly dexterous arms it can catch prey, build a shelter and even open jars. The dazzling array of delicate tasks that they can perform is well documented, but how exactly do they do it? Yoram Yekutieli and colleagues at the Hebrew University and Wiezmann Institute of Science in Israel built a series of oct...

During the past seven years at this hospital the urines of all patients with skeletal tuberculosis have been examined at regular intervals with a view to detecting early renal infection. Our practice is to collect the first specimens passed on three successive mornings in sterile jars. These specimens are centrifuged in sterile tubes and samples of the deposits examined for pus and red cells an...

The excavation of the north house at archaeological site Arucci (Aroche, Huelva) has provided interesting data for understanding city planning in general, and domestic architecture particular. Investigation their environments allowed identification distinct functions which they were intended, including two significant tabernae that connected to one main thoroughfares city. In them, an set ceram...

A 1995 outbreak of dengue haemorrhagic fever (DHF) occurred on Samui Island in Thailand with an incidence of almost 500 cases/100,000 population. To find and develop effective strategies to control this disease through cost-effective vector control programs, entomological studies were carried out on the island between 1996 and 1998. There were two species of DHF vectors, Aedes aegypti and Ae. a...

Earlier studies have shown variation among experimental attempts to establish whether human monozygotic twins that are genetically identical also have identical individual scents. In none of the cases were the dogs able to distinguish all the individual scents of monozygotic twins living in the same environment if the scents were presented to them separately. Ten specially trained police German...

Many factors, both internal and external, influence the chromatic changes of coldblooded vertebrates, and of these, three external variables are recognized as significant—light, heat and moisture. The frog can change its colour, from brown or black through intermediate tints to pale lemon, by changing the contraction and expansion of three types of chromatophores—the epidermal and dermal melano...
