Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

A High Current, Low Ripple, Low Weight PFC Rectifier Using a Standard Power Module

Alfred Rufer

PFC rectifiers are more and more used as front end circuits for low and mid sized apparatus. Especially for the eigh current applications, the size and weight of passive components are an imprtant factor, also for the economic aspect. The number and size o ...

Induction of ob gene expression by corticosteroids is accompanied by body weight loss and reduced food intake

Johan Auwerx

Genetic studies in mice have identified the ob gene product as a potential signaling factor regulating body weight homeostasis and energy balance. It is suggested that modulation of ob gene expression results in changes in body weight and food intake. Gluc ...

Biochemical characterization and solubilization of human NK2 receptor expressed in Chinese hamster ovary cells

Gerardo Turcatti

The human ileum neurokinin NK2 receptor has been stably expressed in Chinese hamster ovary (CHO) cells using the dihydrofolate reductase (DHFR) expression system. Amplified cell populations expressing approximately 7 x 105 NK2 receptors/cell were selected ...

High-molecular-weight, water-soluble polyammonium compounds

Jutta Christine Wandrey

The title polymers of dialkenyldialkylammonium compds., useful in the coating and prepn. of paper, are prepd. in high space-time yield by the continuous or batch addn. of H2O-insol. azo compd. initiators in MeOH or DMF to aq. monomers. Thus, adding ten 2-m ...

Influence of mold design on the mechanical properties of high-pressure injection molded polyethylene

High-pressure injection molding (nominal pressure 500 MPa) is known to substantially improve the mechanical properties of high-density polyethylene of a high molecular weight (HMWPE). This work shows that if the mold is equipped with an exit cavity, the te ...

High-molecular-weight, water-soluble polyammonium compounds

Jutta Christine Wandrey

The title polymers, useful in coatings, paper manuf., etc., are prepd. by polymg. H2O-sol. di-2-alkenyldialkylammonium compds. in aq. solns. contg. peroxydisulfates, basic N compds., and pH control agents. Thus, a soln. 2.8 M in (CH2:CHCH2)2NMe2+ Cl-, 0.02 ...

High-molecular-weight, water-soluble polyammonium compounds

Jutta Christine Wandrey

High-mol. wt., water-sol. compds., useful for nonsticky coatings on elec. conductive paper are manufd. by polymn. of 0.01-5 mol.% Z(CO2CH2CR:CR'R2)2 (Z = (CH2)n, (CH:CH)m, O(CH2CH2)p O, arylene, cycloalkylene, n = 0-20; m = 1-4, p = 0-5, R, R1, R2 = H, C1- ...

High-molecular-weight, water-soluble polyammonium compounds

Jutta Christine Wandrey

A method is described for copolymg. diallyldimethylammonium chloride (I) with diallyl malonate (II), diallyl fumarate, acrylamide, or a similar monomer to prep. resins which were useful as elec. conducting coatings on paper, as flocculating agents, etc. Th ...

Micropipette calibration by differential pressure measurements

Philippe Renaud, David Vincent Bonzon

The pipetting of small volumes, typically ranging between a few and one thousand microliters (μl), is widely used in many laboratories and essentially relies on air displacement to aspirate and dispense the liquid contained in a small plastic tip. While th ...
