Reuse of effluent water obtained in different textile finishing processes
Authors: ERDUMLU Nazan , OZIPEK Bulent , YILMAZ Goncagul , TOPATAN Ziynet 
Published: February 2013

Abstract:

The use of clean water in textile finishing is both common and very expensive. Effluent water subjected to advanced methods of physical, chemical, and biological treatment could be used for this purpose. However, information obtained from industry and the literature shows that effluent water obtained from different finishing processes may be reused without being totally purified. In this paper, a method is proposed to determine the viability of reusing effluent water obtained from different textile finishing processes of cotton fabrics after just basic treatments. These treatments include; filtering, airing, pH regulating and ion exchange. Effluent water obtained in different textile finishing processes was analysed in terms of pH value, COD (Chemical Oxygen Demand), SS (Suspended Solids), colour, hardness and conductivity. Effluent water for treatment and the process where the treated water was reused were determined by means of the proposed method, based on a multiple criteria decision making approach. A laboratory scale trial was conducted to investigate the efficiency of treatment.
Evaluation of production effectiveness in garment companies through key performance indicators
Authors: Spahija S. , Shehi E. , Guxho G. 
Published: February 2013

Abstract

Key Performance Indicators help an organisation to improve productivity and to evaluate its success. Improved
productivity is an essential part of increasing the value-added services that companies can offer to clients and
hence their competitiveness. By using Key Performance Indicators, a company can establish baseline figures
against a number of important areas. They can be considered like a health check on a company or a diagnosis
of where a company can improve its performance. The definition of what they are and how they are measured
does not change often, but Key Performance Indicators may change as the organisation's goals change. In this
paper we present and discuss the way to establish Key Performance Indicators to evaluate the production
effectiveness of garment companies. The KPIs are being tested in several garment companies in Albania and
actually implemented in 25 companies.

ABSTRACT
Since the description by Stein and Leventhal the enigma of polycystic ovarian syndrome keeps on unfolding day by day. Recently due to changes in lifestyle the incidence of adolescent PCOS is on rise and form the basis of metabolic and endocrinological diseases in later life. Hence, it is of utmost importance to recognize the pathology at earliest and treat it before the features become resistant.

Young Australian adults with NF1 have poor access to health care, high complication rates, and limited disease knowledge
Authors: Oates Emily C. , Payne Jonathan M. , Foster Sheryl L. , Clarke Nigel F. , North Kathryn N. 
Published: February 2013

AbstractNeurofibromatosis type 1 (NF1) is a multisystem disease associated with a lifelong risk of debilitating and potentially life‐limiting complications, however many adults with NF1 have no regular health surveillance. We interviewed and examined 17 young adults with NF1 between the ages of 25 and 33. Most had not been assessed for NF1‐related complications within the previous 8 years, including patients with known serious vascular complications, for example, renal artery stenosis. Acute and/or chronic pain, particularly back and plexiform‐related pain were common symptoms, and despite a significant impact on quality of life, was untreated in most instances. Symptom and examination‐directed imaging revealed serious complications in 41% of the cohort. These included severe spinal cord compression (two cases), a highly SUV avid lesion suggestive of malignancy (one case), and a Juvenile Pilocytic Astrocytoma in a patient without any previous NF1‐related complications. Few study participants had a good understanding of NF1, its associated risks and complications, and many had not sought appropriate medical advice as questions or problems arose. NF1‐related cognitive deficits in some participants, and the lack of a clear source of expert medical advice for adults with NF1 likely contributed to poor health surveillance and management in this population. Overall, these findings suggest that many Australian adults with NF1 are at risk of serious and life‐threatening medical complications, but are not accessing and receiving adequate health care. Access to multidisciplinary adult clinics that specialize in NF1 may address many of the unmet health needs of young adults with NF1. © 2013 Wiley Periodicals, Inc.
Protein Organic Chemistry and Applications for Labeling and Engineering in Live‐Cell Systems
Authors: Takaoka Yousuke , Ojida Akio , Hamachi Itaru 
Published: February 2013

AbstractThe modification of proteins with synthetic probes is a powerful means of elucidating and engineering the functions of proteins both in vitro and in live cells or in vivo. Herein we review recent progress in chemistry‐based protein modification methods and their application in protein engineering, with particular emphasis on the following four strategies: 1) the bioconjugation reactions of amino acids on the surfaces of natural proteins, mainly applied in test‐tube settings; 2) the bioorthogonal reactions of proteins with non‐natural functional groups; 3) the coupling of recognition and reactive sites using an enzyme or short peptide tag–probe pair for labeling natural amino acids; and 4) ligand‐directed labeling chemistries for the selective labeling of endogenous proteins in living systems. Overall, these techniques represent a useful set of tools for application in chemical biology, with the methods 2–4 in particular being applicable to crude (living) habitats. Although still in its infancy, the use of organic chemistry for the manipulation of endogenous proteins, with subsequent applications in living systems, represents a worthy challenge for many chemists.
Biodegradation paths of Mater‐Bi®/kenaf biodegradable composites
Authors: Re Giada Lo , Morreale Marco , Scaffaro Roberto , La Mantia Francesco P. 
Published: February 2013

AbstractComposites obtained from biodegradable polymers and natural–organic fillers are attracting increasing interest, thanks to the environmental advantages they promise. On the other hand, the real biodegradation performance of a biodegradable polymer/natural organic filler composite should be assessed by performing specific biodegradation tests. These are often carried out under laboratory conditions, but more realistic conditions should be taken into account. In this work, a systematic study on the biodegradation of kenaf fiber‐filled Mater‐Bi® composites in different environments is presented, and some interesting parameters for the understanding of the optimum way to obtain a fast degradation of the composites can be extrapolated. In particular, it was found that the presence of the fibers, the environmental conditions, and the manufacturing procedures of the composites can significantly affect the biodegradation behavior. The results can be used to determine the most suitable disposal environments for biodegradation of Mater‐Bi®‐based wastes. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Facile Synthesis and Photophysical Properties of Sphere–Square Shape Amphiphiles Based on Porphyrin–[60]Fullerene Conjugates

AbstractMolecules constructed from a combination of zero‐dimensional ([60]fullerene (C60)) and two‐dimensional (porphyrin (Por)) nanobuilding blocks represent an intriguing category of sphere–square “shape amphiphiles”. These sphere–square shape amphiphiles possess interesting optoelectronic properties. To efficiently synthesize a large variety of C60–Por shape amphiphiles, a facile route based on Steglich esterification was developed. The synthetic strategy enables the preparation of hydroxy‐functionalized Por precursors (9, 10, 11, 12) with high purity in a one‐pot procedure. All of the C60–Por shape amphiphiles (1, 2, 3, 4, 5) can be readily synthesized in good yields through subsequent Steglich esterification with a highly soluble carboxylic acid derivative of methanofullerene (13). Photophysical studies indicated weak electronic coupling between the C60 and Por moieties and suggest an edge‐to‐face alignment for the moieties. The fluorescence of electronically excited Por portions of each amphiphile was efficiently quenched, which was indicative of electron transfer from 1Por to the C60 group(s). Increasing the number of C60 groups on the shape amphiphiles led to more pronounced quenching of the Por fluorescence, which indicated the potential for more effective generation of charge‐separated species, C60−.Por+., from the photoexcited C60–Por shape amphiphiles.
Application of hybrid SiO2‐coated CdTe nanocrystals for sensitive sensing of Cu2+ and Ag+ ions
Authors: Cao Yongqiang , Zhang Aiyu , Ma Qian , Liu Ning , Yang Ping 
Published: February 2013

ABSTRACTA new ion sensor based on hybrid SiO2‐coated CdTe nanocrystals (NCs) was prepared and applied for sensitive sensing of Cu2+ and Ag+ for the selective quenching of photoluminescence (PL) of NCs in the presence of ions. As shown by ion detection experiments conducted in pure water rather than buffer solution, PL responses of NCs were linearly proportional to concentrations of Cu2+ and Ag+ ions < 3 and 7 uM, respectively. Much lower detection limits of 42.37 nM for Cu2+ and 39.40 nM for Ag+ were also observed. In addition, the NC quenching mechanism was discussed in terms of the characterization of static and transient optical spectra. The transfer and trapping of photoinduced charges in NCs by surface energy levels of CuS and Ag2S clusters as well as surface defects generated by the exchange of Cu2+ and Ag+ ions with Cd2+ ion in NCs, resulted in PL quenching and other optical spectra changes, including steady‐state absorption and transient PL spectra. It is our hope that these results will be helpful in the future preparation of new ion sensors. Copyright © 2012 John Wiley & Sons, Ltd.
From Oxide‐Supported Palladium to Intermetallic Palladium Phases: Consequences for Methanol Steam Reforming

Published: February 2013

AbstractThis Minireview summarizes the fundamental results of a comparative inverse‐model versus real‐model catalyst approach toward methanol steam reforming (MSR) on the highly CO2‐selective H2‐reduced states of supported Pd/ZnO, Pd/Ga2O3, and Pd/In2O3 catalysts. Our model approach was extended to the related Pd/GeO2 and Pd/SnO2 systems, which showed previously unknown MSR performance. This approach allowed us to determine salient CO2‐selectivity‐guiding structural and electronic effects on the molecular level, to establish a knowledge‐based approach for the optimization of CO2 selectivity. Regarding the inverse‐model catalysts, in situ X‐ray photoelectron spectroscopy (in situ XPS) studies on near‐surface intermetallic PdZn, PdGa, and PdIn phases (NSIP), as well as bulk Pd2Ga, under realistic MSR conditions were performed alongside catalytic testing. To highlight the importance of a specifically prepared bulk intermetallicoxide interface, unsupported bulk intermetallic compounds of PdxGay were chosen as additional MSR model compounds, which allowed us to clearly deduce, for example, the water‐activating role of the special Pd2Ga‐β‐Ga2O3 intermetallicoxide interaction. The inverse‐model studies were complemented by their related “real‐model” experiments. Structure–activity and structure–selectivity correlations were performed on epitaxially ordered PdZn, Pd5Ga2, PdIn, Pd3Sn2, and Pd2Ge nanoparticles that were embedded in thin crystalline films of their respective oxides. The reductively activated “thin‐film model catalysts” that were prepared by sequential Pd and oxide deposition onto NaCl(001) exhibited the required large bimetaloxide interface and the highly epitaxial ordering that was required for (HR)TEM studies and for identification of the structural and catalytic (bi)metalsupport interactions. To fully understand the bimetalsupport interactions in the supported systems, our studies were extended to the MeOH‐ and formaldehyde‐reforming properties of the clean supporting oxides. From a direct comparison of the “isolated” MSR performance of the purely bimetallic surfaces to that of the “isolated” oxide surfaces and of the “bimetaloxide contact” systems, a pronounced “bimetaloxide synergy” toward optimum CO2 activity/selectivity was most evident. Moreover, the system‐specific mechanisms that led to undesired CO formation and to spoiling of the CO2 selectivity could be extracted.
A Self‐Assembled Luminescent Host That Selectively Senses ATP in Water

Published: February 2013

AbstractMetal‐ion‐directed self‐assembly has been used to construct kinetically inert, water‐soluble heterometallic Ru2Re2 hosts that are potential sensors for bioanions. A previously reported metallomacrocycle and a new derivative synthesised by this approach are found to be general sensors for bioanions in water, showing an “off–on” luminescent change that is selective for nucleotides over uncharged nucleobases. Through a change in the ancillary ligands coordinated to the ruthenium centres of the host, an “off–on” sensor has been produced. Whilst this host only shows a modest enhancement in binding affinities for nucleotides relative to the other two host systems, its sensing response is much more specific. Although a distinctive “off–on” luminescence response is observed for the addition of adenosine triphosphosphate (ATP), related structures such as adenine and guanosine triphosphate (GTP) do not induce any emission change in the host. Detailed and demanding DFT studies on the ATP‐ and GTP‐bound host–guest complexes reveal subtle differences in their geometries that modulate the stacking interactions between the nucleotide guests and the ancillary ligands of the host. It is suggested that this change in stacking geometries affects solvent accessibility to the binding pocket of the host and thus leads to observed difference in the host luminescence response to the guests.
