The specific and quantitative composition of the microflora was investigated within the range of the roots of 1-, 2- and 3-year plants in alfalfa cultures with the aim of finding effective new methods of control or prevention of diseases of alfalfa caused by <i>Verticillium albo-atrum</i> and <i>Ascochyta imperfect</i>. The biotic realations between the most numerous saprophytes found on the same sites and the above named pathogens were also studied.

Methods Of Control

For several years we have been investigating the effects of natural and artificial acoustical and electrical phenomena on the behaviour of insects with a view to the development of new methods of control.A. Sounds can be exploited in two ways:–firstly to affect insects whose behaviour is stimulated by naturally-occurring sounds; secondly to use the very rapid pressure changes associated with sounds as a sort of “death ray.”

The Ideal

1. The complacent attitude that fluke is no longer a disease of importance is attacked on the grounds that the recent low incidence of the disease is largely due to a temporary scarcity of the intermediary, Limnaea truncatnla.2. A description is given of methods of making contacts, taking samples, and recording observations in a survey of typical habitats of L. truncatula in England and Wales.3. Twenty-two such habitats are described in some detail.4. These form the basis of a brief discussion on factors contributing to the ideal habitat, knowledge of which is desirable for the elaboration of new methods of control.5. A provisional map showing the distribution of liver fluke in England and Wales is appended.

Methods Of Control

This article examines how colonial violence has been recast in light of Israel's disengagement from Gaza during the summer 2005. By looking at infrastructural networks —the systems that distribute water, electricity, sewage, fuel etc—it explores how far from ending the occupation, disengagement provided a distinct spatial scale from which to experiment new methods of control and repression. In particular, it seeks to expose how these life support systems function as geopolitical sites of spatial control and as biopolitical tools to regulate and suppress life. Specially, it illustrates how the mobilization of discourses, strategies and doctrines, criminalize these critical systems turning them into ‘legitimate’ and ‘pre-emptive’ targets. Drawing on the destruction of Gaza's only power plant and the subsequent sanctions on electricity and fuel, it argues that the destruction and manipulation of infrastructural networks has severe consequences, particularly in public health. In exploring these claims with respect to Gaza, the article draws attention to the ways in which infrastructures play a crucial role in regulating the elastic Gaza's humanitarian collapse. The article closes introducing the concept of infrastructural violence as way to further explore this discussion.

Methods Of Control

For the past four decades, Belém has been considered to be the largest focus of Bancroftian filariasis in the Amazon region and one of the most important ones in Brazil. In 1952, practically one-fifth of the population was infected and it was estimated that there were 2,500 cases of Bancroftian elephantiasis. The major factor considered to be responsible for this situation was the high density of the main vector species: it was calculated that in April 1943 there was a mean of 67 infected mosquitoes per house. A control campaign was initiated in 1952, involving treatment of patients with diethylcarbamazine, as well as control of the vector. In 1956, vector control was discontinued because of a lack of efficient insecticides and financial limitations. Even so, the campaign was very successful and the incidence was reduced from 19.9% to 0.03%. Total eradication could be achieved if new methods of vector control were introduced, such as the use of Reiter's expanded polystyrene balls in cesspits and pit latrines, biological control using pathogenic bacteria, and improvement of basic sanitation.

Methods Of Control

The species Lantana camara, commonly used as ornamental, has spread worldwide becoming one of the world's most important weeds. To develop new methods of control of this plant, it is essential to distinguish it from other species of the same genus, and this is usually accomplished through taxonomic studies of fertile samples. Considering the similarity between L. camara and L. radula, and the consequent difficulty in distinguishing one from the other when only sterile samples are available, this work aimed to investigate the use of the anatomical characteristics of the leaves of both species as tools for supporting correct classification. The leaves of L. camara and L. radula were anatomically examined by light microscopy and scanning electron microscopy. The major differences were observed in the petiole, which presented secretory idioblasts in L. camara. Secretory idioblasts were observed in the leaf blades of L. camara and Crystalliferou idioblasts were found in L. radula. Glandular and nonglandular trichomes as well as the abaxial surface are different in each species. Such results can support the strategies aiming at the control of L. camara without interfering with L. radula.

Methods Of Control

The problem of longitudinal gauge variations in hot- and cold-rolled sheet and strip metal is considered. It is suggested that they are caused mainly by elastic distortions of the mill in response to variations in the separating force between the rolls. A unique relation is shown to exist between the roll force and the thickness of the strip leaving the rolls, and this forms the basis of two new methods of continuous automatic control of gauge. These methods are independent of direct measurement of the thickness of the sheet or strip during rolling. They employ an electrical roll-force measuring element the output of which, after suitable modification, continuously adjusts either the position of the rolls or the tension applied to the strip, so that a substantially constant thickness is maintained in the rolled material. Some preliminary experiments on a 10 inches by 10 inches two-high mill have demonstrated that these methods of control are correct in principle.
