Second thoughts about double effect.
… doctrine known as the Doctrine of Double Effect (DDE) and its applications to issues in war and medicine. DDE maintains that it is harder to justify causing harm intentionally than it is to justify causing it foreseeably. Some of the strongest support for DDE comes from cases where an agent …

Applications of aerobic and anaerobic bacteria in the fields of biological degradation of contaminants and biological wastewater treatment
… and 1,1-bis (p-Chlorophenyl)-2-dichloroethylene (DDE) utilising pure bacterial cultures. The second investigation dealt with the degradation of DDE and polychlorinated Biphenyl’s (PCB’s) utilising anaerobic sediments and soils from New Zealand. The third investigation worked on the Granulation of …

Evaluación preliminar de dos variedades de frijol común (Phaseolus vulgaris L.) inoculadas en diferentes etapas fenológicas con el virus del mosaico amarillo del frijol (BYMV)
… se presentó en el momento de inoculación a los 7 DDE para la variedad Rev. 81 y para la variedad Rev. 84 el menor rendimiento fue a los 15 DDE. En la Etapa II el mayor rendimiento se presentó cuando la inoculación se hizo a los 15 DDE, para la variedad Rev.81 y a los 7 DDE, para la variedad …

Galerkin Approximations of General Delay Differential Equations with Multiple Discrete or Distributed Delays
Delay differential equations (DDEs) are often used to model systems with time-delayed effects, and they have found applications in fields such as climate dynamics, biosciences, engineering, and control theory. In contrast to ordinary differential equations (ODEs), the phase space associated even …

On The Design Of Physical Layer Rateless Codes
… density evolution method. We then show that the DDE method can be used in two-steps to provide the detailed asymptotic performance analysis of SCLDGM codes. We also provide the detailed error-floor analysis of both the LDGM and SCLDGM codes. We also prove a necessary condition for the successful …

Efecto de carbofuran y número de aplicaciones de chlorpyrifos sobre infestaciones de Spodoptera frugiperda (J.E. smith) (Lepidoptera: noctuidae) en maíz (Zea mays) en época de riego y primera
… 20-50, 20-30 días después de la emergencia (DDE) y testigo sin protección. Los periodos de 0-10 DDE recibieron aplicaciones de carbofuran (681 gr i.a) al suelo, los demás recibieron aplicaciones de chlorpyrtfos dirigidos al cogollo a una dosis de 0.5 1/mz. Los resultados demuestran que …

Organization and dynamics of the bacteriophage Mu transpososome
… three essential acidic amino acids (the DDE motif) to the active sites are identified. This work reveals that the transpososome contains two active sites, as defined by the number of required sets of DDE residues, each of which catalyzes cleavage and joining of one transposon DNA end to …

Ecological and Trophic Distribution of Pesticides in Lack Poinsett, South Dakota
… insects and fish. Concentrations of aldrin, DDD, DDE, DDT, dieldrin, endrin, heptachlor, heptachlor epoxide, lindane, methoxychlor, and toxaphene were determined by gas chromatography and thin-layer chromatography. DDT and its metabolites, DDD and DDE, were the highest residues detected in all …

Evaluación preliminar de dos variedades de frijol común (Phaseolus vulgaris L.) inoculadas en diferentes etapas fenológicas con el virus del mosaico común del frijol BCMV
… a los 7, 15, y 21 días después de la emergencia (DDE), y un testigo sin inocular en la etapa I. Se describieron los síntomas y se tomaron los datos de rendimiento. En las dos etapas de investigación ambas variedades resultaron susceptibles al virus. Tendiendo a ser más afectada en los rendimientos …

Períodos críticos de protección contra Spodoptera frugiperda (J.E. smith) (Lepidoptera: noctuidae) para producción de chilote en maíz (Zea mays) de riego y primera
… desde 0 hasta 50 días después de la emergencia (DDE), tiempo en el cual la planta de maíz es suceptible al ataque de cogollero. Los resultados indican que las aplicaciones de cabofurán no ejercen control sobre corgollero en las 2 épocas de siembra. En primera, cuando las infestaciones son menores …

Effects of embryonic exposure to androgen-active endocrine disrupting chemicals in Japanese quail
… to androgen-active EDCs, anti-androgenic DDE and androgenic trenbolone acetate, impairs development of the bursa of Fabricius in Japanese quail, providing a possible mechanism for EDC-induced immunosuppression. The bursa is a primary immune organ responsible for development of the humoral …

Random perturbations of delay differential equations at the verge of instability and periodically driven nonlinear oscillators
… perturbations on delay differential equations (DDE) whose fixed point is on the verge of instability. With appropriate scaling of coordinates, the dynamics close to the fixed point can be cast in the form of a linear DDE perturbed by small noise and small nonlinearities. The instability scenario …

Rapid reductive dechlorination of environmentally hazardous aromatic compounds and pesticides
… biphenyls (PCBs), pentachlorophenol (PCP), p,p'-DDE and Toxaphene, have been widely used in industry and agriculture for more than fifty years. Although they have served their purpose very effectively and at low cost, many of these compounds have been banned in the United States due to their …
