Research and development on IPM was initiated in Pakistan in the 70’s. However, efforts to implement IPM at the farm level did not bear fruit. A major obstacle has been the mindset at the policy level to increase crop production to feed the ever-increasing population. Pesticides became a major instrument of increasing production leading to ‘pesticide treadmill’ situation. Although IPM-FFS “Veha...

We study four measures of problem instance behavior that might account for the observed differences in interior-point method (IPM) iterations when these methods are used to solve semidefinite programming (SDP) problem instances: (i) an aggregate geometry measure related to the primal and dual feasible regions (aspect ratios) and norms of the optimal solutions, (ii) the (Renegar-) condition meas...

BACKGROUND Inverse potential mapping (IPM) noninvasively reconstructs cardiac surface potentials using body surface potentials. This requires a volume conductor model (VCM), usually constructed from computed tomography; however, computed tomography exposes the patient to harmful radiation and lacks information about tissue structure. Magnetic resonance imaging (MRI) is not associated with this ...

Two different types of soft alkyl ether prodrugs incorporating ethyleneoxy groups into the promoiety have been synthesized for a model phenol (acetaminophen, APAP): alkyloxycarbonyloxymethyl type (AOCOM) and N-alkyl-N-alkyloxycarbonyl-aminomethyl type (NANAOCAM). The solubilities in isopropyl myristate, S(IPM), and water, S(AQ), partition coefficients between IPM and pH 4.0 buffer, K(IPM:4.0), ...

The retinal interphotoreceptor matrix (IPM) occupies the space between the neural retina and the retinal pigmented epithelium (RPE), two neuroectoderm-derived epithelia. While the IPM appears to be a major route by which photoreceptor cells receive vital metabolic factors, relatively little is known concerning its structure and function. The studies reported here describe the presence of specia...

Responses of low-frequency neurons in the inferior colliculus (IC) of anesthetized guinea pigs were recorded to interaural phase modulation (IPM) before, during, and after iontophoresis of bicuculline, an antagonist to the inhibitory neurotransmitter GABA. Sensitivity to the direction of virtual motion resulting from IPM is an emergent property of neurons at the level of the IC. One model to ac...

The context-aware application’s main feature is that the program can adjust its behavior according to the context environment. In the traditional object-oriented model, behaviors related to the context may be separated through branching statement, thus greatly reducing the degree of adaptation to environmental changes. This paper, after analyzing the issue of programming context-aware applicati...

The interphotoreceptor matrix (IPM) fills the part of the eye referred to by ophthalmologists as the subretinal space. Located between the outer limiting membrane of the retina and the apical border of the retinal pigment epithelium (RPE), this unique matrix surrounds photoreceptor inner and outer segments projecting from the outer retinal surface. Structure–function activities of fundamental i...

In New Zealand, increasing levels of resistance in diamondback moth (DBM) to recommended synthetic pyrethroid and organophosphate insecticides were monitored for five years in vegetable Brassica crops until in 1997 they were associated with control failures in three regions. Subsequently, Crop & Food Research initiated a two-year IPM implementation programme with financial assistance from gover...
