The protective factors of EC included conservation of food in refrigerator (OR=0.136) and dry place (OR=0.093), regular diet (OR=0.441), intake of fresh vegetables (OR=0.328),cereal (OR=0.583), and allium vegetables (OR=0.397).
This paper gives the experimental results and analyses of the terary near-azeotrope mixture R22/R152a/R114 as an aterlative refrigerant to R12used in domestic refrigerators. The results show that freezing level of the mixture R22/R152a/R114 is basically the same as that of R12, energy comsuption is approximately 3% lower than that of R12. It can sustitute the widely used R12 in domestic refrigerator.
The performances of the refrigeration cycle of the mixture HFC152a/HCFC22 and HFC152a/HFC125 used as a refrigerant for domestic refrigerators were theoretically calculated and analyzed. The experimental study on the main performances of refrigerator refrigeration cycle was conducted by using the two mixtures substituting for CFC12 under the condition of unchanged original refrigerator construction and its optimization composition and charge amount.
All the testers are exsanguinated the blood 5ml from the outer veins, heparin anticoagulant, spin the tubes at 3000r/min for 5min, isolation blood serum 1.5ml into Eppendorf test tube, and put it in the refrigerator in -30℃ for testing.
The refrigerators operate at a circulation rate of ～2-10 μmol/s and consume 1-2 l/day of liquid helium for maintaining their operation.
The refrigerators are designed to cool photodetectors or samples in experiments that do not require a high refrigerating capacity.
The results of spectral kinetic studies of several fluoride crystals activated by Yb3+ and Tm3+ ions are presented, and their possible application as cooling elements of optical refrigerators is discussed.
The possibility of using an n-type Bi2-xSbxTe3 solid solution in thermoelectric refrigerators at T>amp;lt;200 K is considered.
The model and the method presented in this paper could be used to design vapour compression units such as domestic refrigerators and air conditioners.
Nous avons étudié l'influence de la réfrigération et du chauffage sur le contenu en ADN dans le foie du rat, de même que l'influence des solvents organiques employés dans les techniques histologiques.
La réfrigération ne cause pas de perte importante d'ADN.
Les composants volatils du fromage Cheddar, obtenus par la distillation de la matière grasse et recueillis dans le tube réfrigéré à l'azote liquide, étaient neutralisés et analysés en phase gazeuse sur 3 colonnes différentes.
Elizabeth Frig our research dietitian, is very experienced and has been asked to present at national and international clinical trial meeting.
The essence of the reduction is to treat the four possible locations of frig as four colors.
We know that a group G is functionally complete if and only if it is either trivial or a finite simple non-Abelian group [Ref.
If X is a Banach space and X' is its conjugate, then a subset Y of X' is called madmissible for X if a) the topology σ(X, Y) is Hausdorff, b) the identity embedding of (X, σ(X, Y)) into X is universally measurable (Ref.
A p53 mutation is required for stable transformation of REF52 cells by themyc andras oncogenes
To study some additional factors necessary for such transformation, c-myc and N-rasAsp12 were consecutively introduced into REF52 cells by retroviral infection, and the cell cultures obtained were analyzed.
Attempts to obtain stable transformed cell lines by transduction ofras into REF52 cells not expressing exogenousmyc were unsuccessful.
