The off-stoichiometric Ni(2)MnGa Heusler alloy is a magnetic shape-memory alloy capable of reversible magnetic-field-induced strains (MFIS). These are generated by twin boundaries moving under the influence of an internal stress produced by a magnetic field through the magnetocrystalline anisotropy. While MFIS are very large (up to 10%) for monocrystalline Ni-Mn-Ga, they are near zero (<0.01%) ...

In recent years, a lot of investigations have been focused on ferromagnetic shape memory alloys (FSMAS), such as Ni2MnGa, FePd, CoNi and FeNiCoTi [1–4], due to their large magnetic-field induced strain (MFIS) and high response frequency. Of the above alloys Ni Mn Ga alloy is the only known Heusler alloy exhibiting thermal martensitic phase transformation. It is reported up to now that a maximum...

This study examines whether microfinance institutions (MFIs) that serve women borrowers at the base of the economic pyramid are likely to adopt a written code of positive organizational ethics (POE). Using econometric analysis of operational and economic data of a sample of MFIs from across the world, we find that two contextual factors—poverty level and lack of women’s empowerment—moderate the...

BACKGROUND As a symptom of multiple sclerosis (MS), fatigue is difficult to manage because of its unknown etiology, the lack of efficacy of the drugs tested to date and the absence of consensus about which would be the ideal measure to assess fatigue. OBJECTIVE Our aim was to assess the frequency of fatigue in a sample of MS patients and healthy controls (HC) using two fatigue scales, the Fat...

A Ni–Mn–Ga single crystal with a phase transformation temperature above 350 K is investigated. The material demonstrates a magnetic field-induced strain (MFIS) of 7% at room temperature and of 4.2% at 350 K. The temperature dependence of the magnetic anisotropy and of the saturation magnetization has been studied in detail. At 350 K a maximum magnetic stress of 1.6 MPa and a twinning stress of ...

The article examines the models of microfinance institutions (MFIs) and some alterations in this field. The regional distribution of MFIs has been shown, as well as their main ties with the real economy against a background of commercial banks. The study also provide some findings on the influence of the financial crisis, which erupted in the late 2007, on the microfinance sector. Therefore, th...

Metal-ferroelectric-insulator-semiconductor (MFIS) devices were successfully fabricated using poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) and poly (methyl methacrylate): titanium dioxide (PMMA:TiO2) nanocomposite as ferroelectric and insulator films, respectively on n-type silicon (n-Si) substrate. Both ferroelectric and insulator films were prepared by sol-gel spin coating method. ...

Credit agents in microfinance institutions (MFIs) must be given incentives to acquire information on potential borrowers and select them in accordance with the MFI’s objectives. We show that while giving incentives has no cost in for-profit MFIs, it is costly in propoor MFIs: When repayment and wealth are positively correlated, a pro-poor MFI cannot obtain the selection of poor clients in the p...

The purpose of this paper is to examine the role of micro finance in the empowerment of people and the realisation of financial inclusion in India. While there are reservations about the efficacy of MFIs in handling public money, their growth and achievements demand attention and appreciation. Today the MFIs want the government to empower them for mobilising savings. With increasing demand for ...

The study's objective was to develop a real-time measurement for fatigue and to evaluate whether it is an effective clinical trial outcome measure compared with the Fatigue Severity Scale (FSS) and the Modified Fatigue Impact Scale (MFIS). Forty-nine subjects with MS and an FSS >4 recorded Real-Time Digital Fatigue Scores (RDFSs) on a wrist-worn device four times a day over 3 weeks. Scores were...
