Moving to Opportunity (MTO) offered public housing residents the opportunity to move to low-poverty neighborhoods. Several years later, boys in the experimental group fared no better on measures of risk behavior than their control group counterparts, whereas girls in the experimental group engaged in lower-risk behavior than control group girls. The authors explore these differences by analyzin...

A novel and efficient procedure to prepare highly oxidised aryltetralin lignans, such as isopodophyllotoxone and (-)-aristologone derivatives, by oxidation of podophyllotoxin and galbulin with methylrhenium trioxide (MTO) and novel MTO heterogeneous catalysts is reported. It is noteworthy that in the case of isopodophyllotoxone derivatives the functionalisation of the C-4 position of the C-ring...

Formaldehyde (HCHO), generating from hydrogen transfer (HT) of reactant, is significant for autocatalysis initiation and deactivation in methanol-to-olefins (MTO), but hitherto, its evolution throughout the reaction has not been thoroughly revealed. Herein, by established colorimetric analysis method, HCHO MTO dimethyl ether (DME)-to-olefins (DTO) reactions over SAPO-34 was situ quantitatively ...

the thermodynamic of the known and very effective catalytic system, hydrogen peroxide (h2o2) and methyltrioxorhenium (mto) is studied in different solvents using uv-visible spectroscopic method. the thermodynamic parameters (δg, δh and δs) for two equilibrium reactions, mto + h2o2 ⇌ a + h2o and a + h2o2 ⇌ b.h2o (a, [mere(o)2(o2)]; b.h2o, [mere(oh2)(o)(o2)2]), are determined. the obtained free e...

In small-pore zeolite catalysts, where the size of the pores is limited by eight-ring windows, aromatic hydrocarbon pool molecules that are formed inside the zeolite during the Methanol-to-Olefins (MTO) process cannot exit the pores and are retained inside the catalyst. Hydrocarbon species whose size is comparable to the size of the zeolite cage can cause the zeolite lattice to expand during th...

The aim of this study was to determine the acute and chronic effects of low doses of long chain (LC) n-3 polyunsaturated fatty acids (PUFA) (<100 mg per day) on plasma LC n-3 PUFA levels using a novel delivery form; bread containing microencapsulated tuna oil (MTO). Six omnivores (three men and three women) participated in the acute study, which involved ingesting a prototype MTO bread containi...

Survey nonresponse and attrition undermine the validity of many and possibly most econometric estimates. In this paper, we discuss simple methods for assessing the nature of the damage caused by such problems. A fundamental component of the methods we discuss is partial randomization of non–response. We evaluate the performance of simple grouped data estimators for sample selection (a là Gronau...

We study adult economic and health outcomes in the Moving to Opportunity (MTO) demonstration, a randomized housing mobility experiment in which families living in highpoverty U.S. public housing projects in five cities were given vouchers to help them move to private housing units in lower-poverty neighborhoods. An “experimental” group was offered vouchers valid only in a low-poverty neighborho...

As the use of pesticides in agriculture is increasing at an alarming rate, food contamination by pesticide residues becoming a huge global problem. It essential to develop sensitive and user-friendly sensor device quantify trace levels herbicide samples. Herein, we report electrocatalyst made up yttrium iron garnet (Y3Fe5O12; YIG) graphitic carbon nitride (GCN) attain picomolar-level detection ...
