الگو (pattern) آن چیزی است که شکل گرفته و در یک گروه اجتماعی به این منظور که بعنوان مدل یا راهنمای عمل در رفتارهای اجتماعی بکار آید حضور می یابد و الگوهای کلی رفتار، عبارتند از شیوه های منتظم در رفتار که در جامعه از زمان گذشته تا کنون مشاهده می شوند و انسانها از طریق آموزش و جذب در یک فرهنگ خاص ، شبکه ای از عادات و واکنشهایی را کسب می کنند که موجبات تطابق آنان را به شیوه های کلی رفتار گروه فراه...

BACKGROUND Intravascular fluid shifts, mechanical ventilation and inhalational anesthetic drugs may contribute to intraoperative lung injury. This prospective observational study measured the changes in respiratory impedance resulting from inhalational anesthesia and mechanical ventilation in adults undergoing transurethral resection of bladder tumors. The components of respiratory impedance (r...

This paper studies the optimal choice of home equity release products. The decision problem of a retiring couple is modeled that holds the major fraction of their wealth as home equity and faces longevity, long-term care, house price, and interest rate risk. The couple can choose to buy annuities, long-term care insurance, and to borrow against the home using different equity release products. ...

Article history: Received: 26.4.2015. Received in revised form: 16.9.2015. Accepted: 22.9.2015. The scattered point cloud data, which comes from such small-sized objects with complex free-form surface as shelled shrimp, is processed as error points removing, points filtering, holes filling, clouds segmenting, etc. using CATIA V5 R20. The principle of data processing and skills utilized in the o...

3 4 q Ž If the low energy cross section for HeqpTM Heqe qn , the ‘hep’ reaction, is R20 times larger than the best but e . uncertain theoretical estimates, then this reaction could significantly influence the electron energy spectrum produced by solar neutrino interactions and measured in the SuperKamiokande, SNO, and ICARUS experiments. We compare predicted energy spectra for different assumed...

The R20 neurons of Aplysia exhibit frequency-dependent spike broadening. Previously, we had used two-electrode voltage clamp to examine the mechanisms of this spike broadening (Ma and Koester, 1995). We identified three K+ currents that mediate action-potential repolarization: a transient A-type K+ current (I(Adepol)), a delayed rectifier current (IK-V), and a Ca(2+)-sensitive K+ current(IK-CA)...

The aim was to evaluate the ventilation inhomogeneity (VIH) by multiple-breath nitrogen washout test (MBNW) after COVID-19 and identify relationship of lung clearance index (LCI) with other functional parameters respiratory system. Methods. cross-sectional study included 35 patients (97% men); median age 44 years. Spirometry, body plethysmography, diffusing capacity for carbon monoxide (DL co )...

A perceived advantage of cap-and-trade programs over more prescriptive environmental regulation is that enhanced compliance flexibility and cost effectiveness can make more stringent emissions reductions politically feasible. However, increased compliance flexibility can also result in an inequitable distribution of pollution. We investigate these issues in the context of Southern California’s ...

This paper studies the interaction between inequality and house prices using an incomplete market model with heterogeneous households. The model links cross-sectional household portfolio saving decisions to housing market outcomes. It illustrates a new price formation mechanism in which an investment motive among the wealthy plays a key role. A quantitative application of the theory rationalize...
