RIC-HSCT for MF/SS
No full textAdvanced-stage mycosis fungoides and Sezary syndrome (MF/SS) have a poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT), particularly using a reduced-intensity conditioning (RIC) regimen, is a promising treatment for advanced-stage MF/SS. We performed RIC-HSCT in nine patients with advanced MF/SS. With a median follow-up period of 954days after HSCT, the estimated 3-year overall survival was 85.7% (95% confidence interval, 33.4-97.9%) with no non-relapse mortality. Five patients relapsed after RIC-HSCT; however, in four patients whose relapse was detected only from the skin, persistent complete response was achieved in one patient, and the disease was manageable in other three patients by the tapering of immunosuppressants and donor lymphocyte infusion, suggesting that graft-versus-lymphoma effect and "down-staging" effect from advanced stage to early stage by HSCT improve the prognosis of advanced-stage MF/SS. These results suggest that RIC-HSCT is an effective treatment for advanced MF/SS
Hydrologic assessment of check dam performances in semi-arid areas: a case study from Gujarat, India
No full textIn semi-arid India, managed aquifer recharge (MAR) is often used to enhance aquifer storage, and by implication, water security, and climate resilience, by capturing surface runoff, mainly through check dams implemented at the community level. Despite their extensive use, the design of these structures typically does not follow a systematic method to maximize performance. To aid in the improvement of check dam design parameters and location siting, we develop a dynamic tool, which integrates the daily water balance of a check dam with analytical infiltration equations to assess check dam performance measured as temporal dynamics of storage, infiltration, and evaporation. The tool is implemented in R environment and requires meteorological and hydrogeological data, as well as check dam geometry and nearby well-abstractions, if any. The tool is applied to a case study in Saurashtra in Gujarat, where field visits were conducted. Simulations show that typical check dams in the area are able to store a volume between three and seven times their storage capacity annually. Infiltration volumes highly depend on hydroclimatic and hydrogeological conditions, as well as the formation of a clogging layer, highlighting the importance of site selection and periodic maintenance. The tool is validated with data from a previous study in Rajasthan, where daily water balance parameters were monitored. Validation results show an average R 2 of 0.93 between the simulated and measured water levels. The results are adequate to suggest that the tool is able to assist in check dam planning in semi-arid environments

The contribution of sustainability practices and microfinance on micro-enterprise business performance in Malaysia: the moderating role of business location / Noorul Hafizah Hashim, Hisham Mohammad and Md. Mahmudul Alam
No full textThis study aimed to examine the impact of sustainability practices (SP) and microfinance (MF) on the financial performance (FP) and non-financial performance (NFP) of micro-enterprises in Malaysia. This study also introduced business location as a moderating variable in the model. A cross-sectional research design using a quantitative research approach was adopted. The data were collected from the owners/managers of micro-enterprises of provision stores in retail sectors covering 12 districts in Kedah. Total 300 self-administrated questionnaires were distributed to micro-enterprise owners/managers, and 282 were utilised for further analysis. Data were further analysed using SPSS and SmartPLS 4 software through the structural equation technique. The results showed a significant direct effect of SP and MF on the FP and NFP of micro-enterprises. Meanwhile, business location significantly moderated the relationship between SP, MF and NFP but not FP of micro-enterprises. This study is the first in examining business location as a moderator on the relationship between SP, MF, FP and NFP in a single model. The findings from this study would enrich the current literature on RBV theories by incorporating SP and MF in the context. Furthermore, this study could also contribute to the government and microfinance institutions designing or strengthening the microfinance programs, infrastructure and guidelines, particularly in improving the overall business performance of MSMEs
Preparation of mono-sized epoxy/MF microcapsulesin the appearance of polyvinyl alcohol as co-emulsifier
No full textFor epoxy microcapsules embedded in concrete as mechanic-triggered self-healing adhesive, globular shape with uniform size is the basic requirement to ensure the solid shell broken and the liquid core released at a designed stress. In this paper, monodispersed melamine\u96formaldehyde (MF) resin-walled epoxy E-51 microcapsules were successfully fabricated in an in situ polycondensation process, in which a certain amount of polyvinyl alcohol (PVA) solution was added as coemulsifier to control the microcapsules\u92 shape and size. Detail investigation shows, with the cooperation of PVA, the microcapsule morphologies and size distribution were ease to be adjusted by the parameters such as emulsifying agents, agitation rate, pH value and acidification time
ACT Family Violence Intervention Program review
No full textThis paper reports on a review of the Australian Capital Territory’s Family Violence Intervention Program, which provides an interagency response to family violence matters.
The scope of the review was to analyse the program’s activities and outcomes using 2007–08 data provided by participating agencies, supported by in-depth interviews with key stakeholders including victims whose matters had been finalised in court. After the completion of this report, additional data from 2008–09 and 2009–10 was made available by some Family Violence Intervention Program (FVIP) participating agencies. Although not within the scope of this evaluation, these data pointed to some preliminary improvements in the FVIP
NF membrane fouling by aluminum and iron coagulant residuals after coagulation-MF pretreatment
No full textThe effects of coagulant residuals on fouling of a nanofiltration (NF) membrane were investigated. Experiments were carried out with a laboratory-scale microfiltration (MF)-NF setup and a pilot MF-NF plant. In the laboratory-scale experiments, NF feed water was pretreated with poly-aluminum chloride (PACl) or alum followed by MF. NF membrane permeability declined when the feed water contained residual aluminum at 18 μg/L or more, but not when it was lower than 9 μg/L. When pretreated with ferric chloride, no substantial decline of NF membrane permeability was observed: residual iron did not affect the permeability. When SiO2 was added to the water before the pretreatment with PACl, the NF membrane permeability declined at about double the speed. Thermodynamic calculations and elemental analysis of foulants recovered from the membranes indicated that the majority of inorganic foulants were compounds composed of aluminum, silicate, and possibly potassium. In the pilot plant, NF feed was pretreated by PACl. Transmembrane pressure for NF doubled over 4.5 months of operation. Although the aluminum concentration in the NF feed was not high (30 μg/L), analysis of membrane foulants revealed excessive accumulation of aluminum and silicate, also suggesting that aluminum residuals caused the membrane fouling by alumino-silicates or aluminum hydroxide
Integrative approaches to protein homology search
No full textAlam I. Integrative approaches to protein homology search. Bielefeld (Germany): Bielefeld University; 2005.Many methods have been developed to search for homologous members of a protein family in databases, and the reliability of results and conclusions may be compromised if only one method is used, neglecting the others. This thesis introduces an integrative approach to homology search and shows that an effective combination of homology search methods reveals superior results (Alam et al., 2004). Two protein sequence database search methods (called CHASE (Comparative Homology Agreement SEarch) and GenCHASE (Genomic CHASE)) were developed, which serve as a major step to improve the detection of remote homology. CHASE combines methods that search proteins in protein databases. We implemented some improvements in CHASE that we now call CHASE2. An evaluation based on the SCOP database reveals that, on average, a coverage of 55 percent and 49 percent can be obtained by CHASE2 and CHASE respectively, in searches for distantly related homologues (i.e. members of the same superfamily, but not the same family - the most difficult task), accepting only 10 false positives, while the individual methods obtain a coverage of 31 to 44 percent. GenCHASE combines methods that search proteins in genomic sequences and predict gene structure. Using GenCHASE we have found several candidates for ABC, S100, and Cadherin proteins. Experimental verification of some of these candidates is underway
Biomass‐Derived Materials for Interface Engineering in Organic/Perovskite Photovoltaic and Light‐Emitting Devices
No full textCompared to their inorganic counterparts, organic optoelectronic devices receive considerable attention due to their lower cost, mechanical flexibility, bandgap engineering, and solution processability. In particular, achieving sustainability in solar cells and light emitting devices is an important milestone in the development of green electronics. This has facilitated a close collaboration between different technological fields, opening new ways for low-cost production and application of biomaterials. Recently, biomass materials, mainly derived from plants, animals and microorganisms, have emerged as effective candidates to modify the interfacial properties, and thus enhance the performance, lifetime, and stability of organic solar cells (OSCs), perovskite solar cells (PVSCs), and organic light-emitting diodes (OLEDs). Compared to the commonly used synthetic interfacial materials, the use of biomass interlayer materials (BIMs) is still in its embryonic stages; however, their nontoxicity, biorelevance, sustainability, special proton conductivity, and rich functional groups are stimulating researchers around the globe to fabricate novel devices with improved efficiency. Herein, a comprehensive review of BIMs and their importance in next-generation optoelectronic devices is provided. A well-targeted comparison between the electrical and physical properties of different BIMs is provided, and how such characteristics improve the performance of three key optoelectronic devices: OSCs, PVSCs and OLEDs, is discussed
