In this work, a comparative study on different drill point geometries and feed rate for composite laminates drilling is presented. For this goal, thrust force monitoring during drilling, hole wall roughness measurement and delamination extension assessment after drilling is accomplished. Delamination is evaluated using enhanced radiography combined with a dedicated computational platform that integrates algorithms of image processing and analysis. An experimental procedure was planned and consequences were evaluated. Results show that a cautious combination of the factors involved, like drill tip geometry or feed rate, can promote the reduction of delamination damage.

Malaria remains one of the most prevalent tropical and infectious diseases in the world, with an estimated more than 200 million clinical cases every year. In recent years, the mosquito stages of the parasite life cycle have received renewed attention with some progress being made in the development of transmission-blocking strategies. From gametocytes to late ookinetes, some attractive antigenic targets have been found and tested in order to develop a transmission blocking vaccine, and drugs are being currently screened for gametocytocidal activity, and also some new and less conventional approaches are drawing increased attention, such as genetically modified and fungus-infected mosquitoes that become refractory to Plasmodium infection. In this review some of those strategies focusing on the progress made so far will be summarized, but also, the challenges that come from the translation of early promising benchwork resulting in successful applications in the field. To do this, the available literature will be screened and all the pieces of the puzzle must be combined: from molecular biology to epidemiologic and clinical data.

A B S T R A C TThe characteristics of carbon fibre reinforced laminates had widened their use, from aerospace to domes-tic appliances. A common characteristic is the need of drilling for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, delamination assessment methods based on radiographic data are compared and correlated with mechanical test results (bearing test).

The syndrome of transient headache and neurologic deficits associated with cerebrospinal fluid lymphocytosis (HaNDL) is characterized by 1 or more episodes of severe headache, transient neurologic deficits, and lymphocytic pleocytosis in the cerebrospinal fluid. It is a benign and self limited disorder seldom reported in pediatric age. We report the case of a 14-year-old girl who suffered from 2 episodes of headache with transient focal neurologic deficits and pleocytosis consistent with the syndrome of HaNDL. This entity should be taken into account as a differential diagnosis in otherwise healthy children presenting with recurrent headache and acute neurologic deficits. Repeated use of invasive and expensive laboratory and imaging investigations can be avoided when the diagnosis of the syndrome of HaNDL is correctly established.
