In order to understand how changes in individual performance (growth, survival or reproduction) influence population dynamics and evolution, ecologists are increasingly using parameterized mathematical models. For continuously structured populations, where some continuous measure of individual state influences growth, survival or reproduction, integral projection models (IPMs) are commonly used...

Despite its theoretical prominence and sound principles, integrated pest management (IPM) continues to suffer from anemic adoption rates in developing countries. To shed light on the reasons, we surveyed the opinions of a large and diverse pool of IPM professionals and practitioners from 96 countries by using structured concept mapping. The first phase of this method elicited 413 open-ended res...

The aim of this investigation was to assess the applicability of lipid bilayer alteration using a combination of isopropyl myristate (IPM) and glyceryl monocaprylate (GEFA-C(8)) to the enhancement of pentazocine (PTZ) permeation through hairless mouse skin. The skin permeability of PTZ was enhanced by increasing the concentration of GEFA-C(8) up to 10% w/w in combination with IPM. Attenuated to...

This study assessed the cost and effectiveness of a building-wide cockroach integrated pest management (IPM) program compared with bait alone treatment in public housing. In total, 12 buildings (66 apartments) were treated and monitored for cockroach infestations over 7 mo. The buildings were divided into two groups: bait treatment and IPM. Apartments in the bait alone group were treated with M...

We analyzed the possible causes of imipenem (IPM) resistance in multidrug-resistant isolates of Acinetobacter baumannii. Comparison of the outer membrane protein (OMP) profiles of two genomically related strains (Ab288 [IPM sensitive] and Ab242 [IPM resistant]) indicated the conspicuous loss of a 29-kDa polypeptide in the Ab242 strain. No carbapenemase activity was detected in any of these stra...

Many low-income housing units in the United States continue to have chronic German cockroach, Blattella germanica (L.), infestations and high prevalence of cockroach allergens despite the availability of highly effective cockroach control products. Several studies have demonstrated the greater effectiveness of integrated pest management (IPM) compared with routine chemical interventions in apar...

A retrospective comparative study was done to compare the outcome of intermittent Pringle manoeuvre (IPM) and selective hepatic vascular exclusion (SHVE) in 19 major hepatectomies in non-cirrhotic patients that were done from October 2003 to June 2009. Intra-operative blood loss (IBL), total operative time (TOT) and immediate outcome were assessed in the two groups. Thirteen underwent IPM and t...

The interphotoreceptor matrix (IPM) is a mixture of acidic mucosubstances, which can be demonstrated histochemically with cationic dyes, such as Alcian blue, and metal precipitates, such as colloidal iron. In the normal rat retina, staining of the IPM with these reagents is found predominantly at the apical surface of the retinal pigment epithelium (RPE) and, to a lesser extent, at the junction...

The U.S. Environmental Protection Agency encourages school officials to adopt integrated pest management (IPM) to reduce children's exposure to potentially harmful pesticides. In California, the Healthy Schools Act of 2000 (HSA) establishes right-to-know requirements for pesticide use in public schools; requires school districts to designate an IPM coordinator; and requires the California Depar...

Integrated pest management (IPM) involves integrating multiple pest control methods based on site information obtained through inspection, monitoring, and reports. IPM has been deployed to achieve the judicious use of pesticides and has become one of the most important methods of securing agricultural productivity. Despite the efforts made to strengthen IPM during the past decades, overuse as w...
