This paper investigates whether peer effects play an important role in retirement savings decisions. We use individual data from the staff of a university to study whether individual decisions to enroll in a Tax Deferred Account plan sponsored by the university (and the choice of the mutual fund vendor for people who choose to enroll) are affected by the decisions of other employees in the same...
the synthesis of smcl3(thf)3 from smcl3.6h2o is described. the reaction of smcl3(thf)3 with nabh4 in dry thf gave white microcrystalline tris (tetrahydroborato) tris (tetrahydrofuran) samarium (iii), sm(bh4)3(thf)3. the vibrational and magnetic properties of sm(bh4)3(thf)3 have been studied.

Sphingomyelin (SM) synthase has been assumed to be involved in both cell death and survival by regulating pro-apoptotic mediator ceramide and pro-survival mediator diacylglycerol. However, its precise functions are ambiguous due to the lack of molecular cloning of SM synthase gene(s). We isolated WR19L/Fas-SM(-) mouse lymphoid cells, which show a defect of SM at the plasma membrane due to the l...
a r t i c l e i n f o Keywords: 146 Sm– 142 Nd systematics eucrites early planetary differentiation isotope distribution through solar system Short-lived 146 Sm– 142 Nd and long-lived 147 Sm– 143 Nd chronometers have been measured in three cumulate eucrites (Binda, Moore County and Moama). The two major mineral phases (plagioclase and pyroxene) present in these achondrites are characterized by ...

برم-77 یک عضو از خانواده ی رادیوهالوژن ها می باشد که در امر تشخیص و درمان بیماری ها مورد استفاده قرار می گیرد. بیشترین تجمع برم-77 در مغز می باشد و به میزان کمتری در کلیه ها، جگر و مثانه نیز جذب می-شود. رادیوداروهای به دست آمده از برم برای درمان بعضی بیماری ها مثل پارکینسون و پروستات همچنین برای تصویربرداری از کلیه ها به کار می روند. رادیوایزوتوپ برم-77 از بمباران پروتونی سلنیوم در سیکلوترون تو...
Introduction: The target-organ approach of AFAST SM and the AFAST SM -applied fluid scoring system, the FAST DH view, and the TFAST SM format that also assesses heart and lung, encourages the sonographer using these abbreviated formats to look beyond the simplified objective of fluid-positive or fluid-negative FAST approaches. The Global FAST SM approach using these 3 techniques (AFAST SM , TFA...
Mastocytosis is a rare disease characterized by abnormal expansion and accumulation of tissue mast cells (MC) in one or multiple organs. In most adult patients, systemic mastocytosis (SM) is diagnosed. Based on histopathological findings and organ damage, SM is divided into indolent SM (ISM), smoldering SM (SSM), SM with an associated hematologic non-MC-lineage disease (SM-AHNMD), aggressive SM...
∗ ∗ ∗ The biaxial smectic-A (Sm-AB ) phase, appearing in the phase sequence Sm-A –Sm-AB–Sm-C ∗, is analyzed using Landau theory. It is found to possess a helical superstructure with a pitch that is significantly shorter than the pitch of the Sm-C ∗ helical superstructure. The Sm-AB ∗ –Sm-C ∗ transition can be either first or second order, and correspondingly there will be either a jump or conti...
