Mamah Muda Morphogenesis in Indonesia
Authors: . Rewindinar , Triputra Pinckey , Dua Mikhael 
Published: August 2019

There has been changes in the young housewives’ activities, as currently, they not only carry out domestic activities in the house, but also go outside of the house. Activities, such as taking children to school, become part of domestic roles, then meeting other young modern mothers and forming group. This group then raises the “mahmud (mamah muda)” or young moms term. Changes in traditional reproductive roles in the domestic sector are interesting to be analyzed using the Morphogenesis Theory by Margaret Archer. This theory acknowledges that there is an asymmetrical relationship between external structures that are relatively autonomous with internal cultures, and at the same time, there is a reciprocal relationship between the two. The cultural case of this young mothers groups could be used as an example of this Morphogenesis theory.
Constructivist paradigm study using this kind of phenomenological approach was able to explain how the process of morphogenesis change occurred, by conducting in-depth, open-ended interviews to ten mothers in their 30s whose children are in kindergarten/elementary school. This study was able to answer the research purpose, which was young moms, is the reality of changes in structure-culture and culture-structure, produced through the causality of both groups through communication of symbolic convergence that is the exchange of information (material) into symbols (non-material).

AbstractThe purpose of this study was to investigate the potential advantages of the fixed‐jaw technique (FJT) over the conventional split‐field technique (SFT) for cervical and upper thoracic esophageal cancer (EC) patients treated with intensity‐modulated radiotherapy. The SFT and FJT plans were generated for 15 patients with cervical and upper thoracic EC. Dosimetric parameters and delivery efficiency were compared. An area ratio (AR) of the jaw opening to multileaf collimator (MLC) aperture weighted by the number of monitor units (MUs) was defined to evaluate the impact of the transmission through the MLC on the dose gradient outside the PTV50.4, and the correlation between the gradient index (GI) and AR was analyzed. The FJT plans achieved a better GI and AR (P < 0.001). There was a positive correlation between the GI and AR in the FJT (r = 0.883, P < 0.001) and SFT plans (r = 0.836, P < 0.001), respectively. Moreover, the mean dose (Dmean), V5Gy–V40Gy for the lungs and the Dmean, V5Gy–V50Gy for the body‐PTV50.4 in the FJT plans were lower than those in the SFT plans (P < 0.05). The FJT plans demonstrated a reduction trend in the doses to the spinal cord PRV and heart, but only the difference in the heart Dmean reached statistical significance (P < 0.05). The FJT plans reduced the number of MUs and subfields by 5.5% and 17.9% and slightly shortened the delivery time by 0.23 min (P < 0.05). The gamma‐index passing rates were above 95% for both plans. The FJT combined with target splitting can provide superior organs at risk sparing and similar target coverage without compromising delivery efficiency and should be a preferred intensity‐modulated radiotherapy planning method for cervical and upper thoracic EC patients.

Published: August 2019

AbstractHere, a highly conductive cationic membrane is developed directly from natural wood via a two‐step process, involving etherification and densification. Etherification bonds the cationic functional group ((CH3)3N+Cl−) to the cellulose backbone, converting negatively charged (ξ‐potential of −27.9 mV) wood into positively charged wood (+37.7 mV). Densification eliminates the large pores of the natural wood, leading to a highly laminated structure with the oriented cellulose nanofiber and a high mechanical tensile strength of ≈350 MPa under dry conditions (20 times higher than the untreated counterpart) and ≈98 MPa under wet conditions (×5.5 increase compared to the untreated counterpart). The nanoscale gaps between the cellulose nanofibers act as narrow nanochannels with diameters smaller than the Debye length, which facilitates rapid ion transport that is 25 times higher than the ion conductance of the natural wood at a low KCl concentration of 10 × 10−3 m. The demonstrated cationic wood membrane exhibits enhanced mechanical strength and excellent nanofluidic ion‐transport properties, representing a promising direction for developing high‐performance nanofluidic material from renewable, and abundant nature‐based materials.

AbstractAll‐polymer solar cells (all‐PSCs) exhibit excellent stability and readily tunable ink viscosity, and are therefore especially suitable for printing preparation of large‐scale devices. At present, the efficiency of state‐of‐the‐art all‐PSCs fabricated by the spin‐coating method has exceeded 11%, laying the foundation for the preparation and practical utilization of printed devices. A high power conversion efficiency (PCE) of 11.76% is achieved based on PTzBI‐Si:N2200 all‐PSCs processing with 2‐methyltetrahydrofuran (MTHF, an environmentally friendly solvent) and preparation of active layers by slot die printing, which is the top efficient for all‐PSCs. Conversely, the PCE of devices processed by high‐boiling point chlorobenzene is less than 2%. Through the study of film formation kinetics, volatile solvents can freeze the morphology in a short time, and a more rigid conformation with strong intermolecular interaction combined with the solubility limit of PTzBI‐Si and N2200 in MTHF results in the formation of a fibril network in the bulk heterojunction. The multilength scaled morphology ensures fast transfer of carriers and facilitates exciton separation, which boosts carrier mobility and current density, thus improving the device performance. These results are of great significance for large‐scale printing fabrication of high‐efficiency all‐PSCs in the future.

AbstractSensitive, specific, yet multifunctional tattoo‐like electronics are ideal wearable systems for “any time, any where” health monitoring because they can virtually become parts of the human skin, offering a burdenless “unfeelable” wearing experience. A skin‐like, multifunctional electronic tattoo made entirely from gold using a standing enokitake‐mushroom‐like vertically aligned nanowire membrane in conjunction with a programmable local cracking technology is reported. Unlike previous multifunctional systems, only a single material type is needed for the integrated gold circuits involved in interconnects and multiplexed specific sensors, thereby avoiding the use of complex multimaterials interfaces. This is possiblebecause the programmable local cracking technology allows for the arbitrary fine‐tuning of the properties of elastic gold conductors from strain‐insensitive to highly strain‐sensitive simply by adjusting localized crack size, shape, and orientations—a capability impossible to achieve with previous bulk cracking technology. Furthermore, in‐plane integration of strain/pressure sensors, anisotropic orientation‐specific sensors, strain‐insensitive stretchable interconnects, temperature sensors, glucose sensors, and lactate sensors without the need of soldering or gluing are demonstrated. This strategy opens a new general route for the design of next‐generation wearable electronic tattoos.

AbstractHerein, we report the synthesis of a new class of functional silver nanoclusters (AgNCs) capped with pillar[5]arene (P5)‐based host ligands. These NCs are readily prepared through direct synthesis or ligand exchange synthesis and are stable at room temperature for over 4 months. The pillar[5]arene‐stabilized NCs (Ag29(LA‐P5)12(TPP)2) endorse reversible host–guest interactions with neutral alkylamines and cationic quaternary ammonium guests. This results in the formation of spherical assemblies with unparalleled changes in their optical properties including an astonishing circa 2000‐fold luminescence enhancement. This is the highest luminescence enhancement ratio reported so far for such atomically precise NCs. Our synthetic protocol paves the way for the preparation of a new generation of metal nanoclusters protected by macrocyclic ligands with molecular recognition and selectivity toward specific guests.

AbstractVerschiedene aryl‐ und heteroarylsubstituierte 2‐Bromobiaryle werden durch nBu2LaCl⋅4 LiCl in cyclometallierte Lanthanzwischenstufen umgewandelt. Die entstandenen Lanthanheterocyclen sind Schlüsselintermediate für die einfache Herstellung von funktionalisierten 2,2′‐Diiodobiarylen, Silafluorenen, Fluoren‐9‐onen, Phenanthrenen und deren verwandten heterocyclischen Analoga. Röntgenabsorptionsspektroskopie (XAFS) wurde verwendet, um die vorgeschlagenen Strukturen der beteiligten Organolanthanspezies zu erklären.

Published: August 2019

AbstractProPhenol‐Moleküle gehören zur Gruppe der chiralen Azakronen‐Verbindungen und bilden bei Umsetzung mit Alkylmetall‐Reagenzien wie Et2Zn und Bu2Mg spontan einen bimetallischen Komplex. Dieser Komplex hat Lewis‐saure und Brønsted‐basische Reaktionszentren, die eine simultane Aktivierung eines Nukleophils und eines Elektrophils in derselben chiralen Umgebung erlauben. Seit dem ersten Bericht im Jahr 2000 haben Metall‐ProPhenol‐Katalysatoren eine große Bandbreite asymmetrischer Umwandlungen wie Aldol‐, Mannich‐ und Henry‐Reaktionen sowie Alkinylierungen und konjugierte Additionen ermöglicht. Aufgrund der vielfältigen Einsatzmöglichkeiten bei unterschiedlichen Reaktionen erlauben diese Komplexe einen schnellen und atomökonomischen Zugang zu wertvollen komplexen Baugruppen. In diesem Aufsatz beschreiben wir detailliert die Entwicklung und synthetischen Anwendungen dieser vielseitigen Katalysatoren, mit besonderem Blick auf kürzliche Bemühungen, Reaktivität und Selektivität durch Ligandendesign und strukturelle Veränderungen zu verbessern.

Published: August 2019

AbstractThe synthesis and study of a library of cyclic (aryl)(amido)carbenes (CArAmCs), which represent a class of electrophilic NHCs that feature low calculated singlet‐triplet gaps (ΔEST=19.9 kcal mol−1; B3LYP/def2‐TZVP) and exhibit reactivity profiles expected from triplet carbenes, are described. The electrophilic properties of the CArAmCs were quantified by analyzing their respective selenium adducts, which exhibited the largest downfield 77Se NMR chemical shifts (up to 1645 ppm) measured for any NHC derivative known to date, as well as their Ir carbonyl complexes, from which large Tolman electronic parameter (TEP) values (up to 2064 cm−1) were ascertained. The CArAmCs were found to engage in reactions that are typically observed with triplet carbenes, including C−H insertions, [2+1] cycloadditions with alkenes as well as alkynes, and spontaneous oxidation upon exposure to oxygen.
A Greener Alternative Titration Method for Measuring Acid Values of Fats, Oils, and Grease

Published: August 2019

AbstractA greener alternative method is proposed for measuring acid values (AV) of fats, oils, and grease (FOG) based on visual titration. Compared with Official Method Cd 3d‐63 of the American Oil Chemists' Society (AOCS), this greener alternative method can eliminate the use of toluene, which in turn reduces toxicity and cost. A total of 44 samples of yellow and brown grease with AV ranging from 0.13 to 170.37 (mg KOH) g−1 were titrated using both methods. The alternative titration method can provide accurate and reliable results to determine the AV of FOG by various statistical analyses including repeatability, linear regression, f‐test, t‐test, and method accuracy calibration with AOCS Cd 3d‐63. This low‐cost method can be recommended for routine titration in research and development, and in biodiesel plants for most FOG samples.
Evaluation of polymer injection molded parts via density‐based magnetic levitation

Published: August 2019

ABSTRACTThe quality of polymer injection molded parts is definitely related to the molding process. Polymer injection molded parts with different properties differ in density and internal density distribution. This paper proposes a novel evaluation method for polymer injection molded parts through magnetic levitation (MagLev) to detect the differences among products by means of their densities and density distributions. Three cases of polycarbonate lenses are employed as samples in the experiments: lenses produced at different processing parameters, lenses obtained from different cavities in one mold, and those with different interior defects. The lenses obtained at different processing parameters differ in density, and those with different defects exhibit different behaviors during the levitation. The MagLev testing method shows its capability in distinguishing minute differences among the densities (< 0.0005 g cm−3) that even the subtle distinctions among the lenses formed from different cavities in one mold can be detected. Further analysis demonstrates that minute changes in thickness (2.5 μm) can also be detected. The theoretical analysis and experimental results indicate that the MagLev testing method is applicable to the evaluation of polymer injection molded parts. Moreover, the method affords advantages, such as high accuracy, high sensitivity, and convenience. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48431.
Ferroelectric switching in spin‐coated nylons 11 and 12

Published: August 2019

ABSTRACTHere, we investigate the correlation between the crystal structures and the ferroelectric switching by a sinusoidal alternative electric field for spin‐coated nylon 11 films as an odd nylon and for nylon 12 as an even nylon. These spin‐coated nylons afforded thin films with thicknesses ranging from 101 to 125 nm. The obtained thin films were subjected to melt‐quenching, melt‐cooling down, annealing‐quenching, or annealing‐cooling down. These processes were notably related to the resulting crystal structures. In particular, the crystal structures involving twisted bonds in the molecular chains were significantly related to ferroelectricity in both nylon 11 and nylon 12. Namely, the vector component of the amide dipole moments is transverse to the direction of the molecular chains, which is induced by the presence of more twisted bonds and is significantly related to the remanent polarization Pr for both nylons. In nylon 11, the hydrogen bonding interaction between the intermolecular amide dipole moments in the α and δ crystal forms was weakened by the existence of more twisted bonds. In nylon 12, the nonpolar γ crystal form was transformed to a polarizable γ’ crystal form because of the existence of more twisted bonds. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Consumers’ pursuit of material and experiential purchases: A review
Authors: Gilovich Thomas , Gallo Iñigo 
Published: August 2019

AbstractMore than 15 years ago, Van Boven and Gilovich (Journal of Personality and Social Psychology, 85, 2003, 1193) presented evidence that experiential purchases make people happier than material purchases once consumers have covered their basic needs. This experiential advantage has attracted significant attention from researchers in the fields of social and consumer psychology. In this article, we review the literature on this subject. We first define the constructs of experiential and material purchases, and contrast them with previous, related constructs. We then identify and review the different mechanisms that appear to underlie the experiential advantage. Finally, we examine evidence of systematic differences in how people make decisions about material and experiential purchases, focusing on differences in how consumers process information and evaluate options prior to making a purchase.

AbstractBackgroundThe aims of this study were to investigate the link between enhancer of zeste homolog 2 (EZH2) and histone deacetylase (HDAC) in preclinical studies and in human lung cancer tissue microarrays.MethodsEnhancer of zeste homolog 2 and HDAC1 mRNA expression in two lung adenocarcinoma (LUAD) datasets (MDACC and TCGA) were correlated with patient outcomes. We evaluated the association of EZH2 and HDAC1 expression with response to the HDAC1 inhibitor, suberoylanilide hydroxamic acid (SAHA). The response to SAHA was assessed at baseline and after alteration of EZH2 or HDAC mRNA expression in LUAD cell lines.ResultsDirect correlation was found between EZH2 and HDAC1 expression (P < 0.0001). When EZH2 expression was knocked down‐ or upregulated, there was a corresponding decrease or increase in expression of HDAC expression, respectively. Cell lines with high EZH2 expression responded to SAHA treatment with a mean inhibition rate of 73.1% compared to 43.2% in cell lines with low EZH2 expression (P < 0.0001). This correlation was confirmed in non‐small cell lung cancer (NSCLC) specimens from MDACC (Spearman's correlation r = 0.416; P < 0.0001) and TCGA datasets (r = 0.221; P < 0.0001). Patients with high EZH2 and high HDAC1 expression in stage I NSCLC specimens of both datasets had the lowest survival compared to the patients with low expression of either or both markers.ConclusionOur findings show that overexpression of EZH2 is a negative prognostic indicator. Increased EZH2 expression predicts for response to HDAC inhibitors and thus could serve as a biomarker for selecting NSCLC patients for treatment with HDAC inhibitors.
Turncoat Polypeptides: We Adapt to Our Environment

Published: August 2019

AbstractA common interpretation of Anfinsen's hypothesis states that one amino acid sequence should fold into a single, native, ordered state, or a highly similar set thereof, coinciding with the global minimum in the folding‐energy landscape, which, in turn, is responsible for the function of the protein. However, this classical view is challenged by many proteins and peptide sequences, which can adopt exchangeable, significantly dissimilar conformations that even fulfill different biological roles. The similarities and differences of concepts related to these proteins, mainly chameleon sequences, metamorphic proteins, and switch peptides, which are all denoted herein “turncoat” polypeptides, are reviewed. As well as adding a twist to the conventional view of protein folding, the lack of structural definition adds clear versatility to the activity of proteins and can be used as a tool for protein design and further application in biotechnology and biomedicine.

Published: August 2019

AbstractSpectroscopic characterization of AgI‐ion‐mediated C‐AgI‐A and C‐AgI‐T base pairs found in primer extension reactions catalyzed by DNA polymerases was conducted. UV melting experiments revealed that C‐A and C‐T mismatched base pairs in oligodeoxynucleotide duplexes are specifically stabilized by AgI ions in 1:1 stoichiometry in the same manner as a C‐C mismatched base pair. Although the stability of the mismatched base pairs in the absence of AgI ions is in the order C‐A≈C‐T>C‐C, the stabilizing effect of AgI ions follows the order C‐C>C‐A≈C‐T. However, the comparative susceptibility of dNTPs to AgI‐mediated enzymatic incorporation into the site opposite templating C is dATP>dTTP≫dCTP, as reported. The net charge, as well as the size and/or shape complementarity of the metal‐mediated base pairs, or the stabilities of mismatched base pairs in the absence of metal ions, would be more important than the stability of the metallo‐base pairs in the replicating reaction catalyzed by DNA polymerases.

Published: August 2019

AbstractWe report the novel oxygen evolution reaction (OER) catalyst based on cobalt incorporated hydroxyapatite (CoHAP). Our catalyst is prepared on the surface of hydroxyapatite by ion exchange reaction in Co2+ aqueous solution. The cobalt content is approximately 1 wt. % based on ICP‐AES and XPS experiments. XRD, TEM, EDX experiments suggest that individual cobalt ions are adsorbed on the HAP surface in non‐aggregated manner. The cyclic voltammetry (CV) of CoHAP exhibits a weak oxidation peak at 1.10 V which is comparable to CV of in‐situ formed Co−Pi in previous literature. Tafel slope is approximately 80 mV/decade which is independent on the loading amount of CoHAP. The Faradaic efficiency is 94 % measured by quantitative analysis of O2 using gas chromatography. Bulk electrolysis verifies that CoHAP can be utilized OER catalyst at neutral pH with high stability. Our preparation method using hydroxyapatite as a solid phase phosphate source offers a new strategy to fabricate the OER catalysts.
