Published: December 2019

AbstractThe study aimed to explore challenges and solutions in applying green human resource management practices for the sustainable workplace. The field of enquiry is ready‐made garments factories, with the study drawing on qualitative research. The researchers interviewed 12 managers from leading ready‐made garments factories in Dhaka, Bangladesh. The participants interviewed provided rich qualitative data and identified a number of challenges such as a poor level of knowledge, no rules for practicing, a lack of managerial interest and organisational support, high costs of practicing, and high employee turnover as the main challenges in applying green human resource management practices in the factories of the industry. The study also found that strict rules and regulations, monitoring, courses in universities, training programs, and monetary incentives could be effective solutions in applying green human resource management practices in the organisations. This study is amongst the first in academic research to reveal the challenges and solutions in applying green human resource management practices in organisations; therefore, primary data could be useful for academicians and policymakers for further research and subsequent decision‐making.
RETRACTED: Combination of aloin and metformin enhances the antitumor effect by inhibiting the growth and invasion and inducing apoptosis and autophagy in hepatocellular carcinoma through PI3K/AKT/mTOR pathway

AbstractHepatocellular carcinoma (HCC) is a devastating and highly metastatic cancer worldwide. Metformin (MET) is the priority drug for treatment of type 2 diabetes; however, it possesses multiple biological effects like anticancer and hepatoprotective activity. Herein, we examined the effects of aloin (barbaloin) and MET as well as combination treatment in HCC cell line in vitro and in vivo. As a result, aloin and MET alone exhibited inhibitory effects on proliferation and invasion of HepG2 and Bel‐7402 cells. Specially, combination treatment of aloin and MET showed enhanced inhibitory effects in vitro. Aloin and MET alone induced apoptosis and autophagy in vitro. Similarly, aloin and MET cooperated to promote apoptosis and autophagy in HepG2 and Bel‐7402 cells. In the HepG2 xenograft models, aloin in combination with MET confine tumor growth and facilitate apoptosis and autophagy. Both the in vitro and in vivo results showed that aloin and MET alone as well as combination treatment activated the PI3K/AKT/mTOR pathway. Overall, our research demonstrated that the concomitant treatment with aloin and MET enhances the antitumor effect by inhibiting the growth and invasion as well as inducing apoptosis and autophagy in HCC through PI3K/AKT/mTOR pathway.

Published: December 2019

AbstractHeterojunction nanocomposites comprising Nickel‐doped porous ZnO nanosheets decorated with CuInS2 nanoparticles (CuInS2/Ni−ZnO) were prepared through a facile two‐step process. Compared with pure ZnO nanosheets, the Ni doping modifies the energy band structure and narrows the bandgap from 3.1 eV to 2.4 eV, thus enhancing the absorption of visible light. The production of high‐quality CuInS2/Ni−ZnO nanosheets with well‐matched band energy alignment facilitates effective charge transportation and separation. Benefiting from these favorable properties, the as‐prepared CuInS2/Ni−ZnO heterojunction nanosheets exhibit higher photocatalytic activity for reduction of Cr (VI) than CuInS2 and Ni−ZnO in the presence of visible light. The CuInS2/Ni−ZnO‐5 (2 % Ni) composite shows the best photocatalytic activity, which is 7.2 and 5.4 times higher than that of the Ni−ZnO and CuInS2. 98 % of Cr (VI) (50 mg/L) can be reduced within 25 min. Moreover, the activity and structure of the CuInS2/Ni−ZnO catalyst are maintained after five cycles. Combining theoretical calculations and experimental results, a possible photocatalysis mechanism of the CuInS2/Ni−ZnO heterojunction nanocomposites is proposed.
Boron–Nitrogen Double Tweezers Comprising Arylboronic Esters and Diamines: Self‐Assembly in Solution and Adaptability as Hosts for Aromatic Guests in the Solid State

Published: December 2019

AbstractThe thermodynamic stability of 1 : 1 and 2 : 1 boron–nitrogen (B←N) adducts formed between aromatic boronic esters with mono‐ and diamines was studied in solution by NMR and UV‐vis spectroscopy with association energies (ΔG°) ranging from −11 to −28 kJ mol−1. The effect of different substituents in the boronic ester, the nature of the diamine linker, and the effect of the solvent was explored. Stable 2 : 1 B←N adducts with diamines such as 1,3‐diaminopropane were produced in solutions of hydrogen‐bonding acceptor solvents (acetonitrile and ethyl acetate), which can be isolated in the solid state as crystalline solvates, whereas the use of noncoordinating solvents such as 1,2‐dichloroethane afforded mainly 1 : 1 B←N adducts. In suitable combinations, aromatic bis‐pyridyl diamines produced stable 2 : 1 B←N adducts that were isolated either as solvent‐free solids, solvates, or cocrystals. In these crystalline forms, double‐tweezer hosts were observed with an exceptional syn/anti conformational guest‐adaptability driven by simultaneous donor‐acceptor and C−H⋅⋅⋅π interactions in the tweezer cavities, resembling preorganized covalent tweezer hosts. Interestingly, cocrystals with electron‐rich guests such as tetrathiafulvalene and pyrene showed non‐centrosymmetric crystal lattices with infinite π‐stacked donor–acceptor columns.
A simple void node and loop‐free three‐dimensional routing protocol for multi‐hop wireless networks
Authors: Begum Afruza , Hussain Md Anwar 
Published: December 2019

SummaryWireless networks are now very essential part for modern ubiquitous communication systems. The design of efficient routing and scheduling techniques for such networks have gained importance to ensure reliable communication. Most of the currently proposed geographic routing protocols are designed for 2D spatial distribution of user nodes, although in many practical scenarios user nodes may be deployed in 3D space also. In this paper, we propose 3D routing protocols for multihop wireless networks that may be implemented in two different ways depending on how the routing paths are computed. When the routing paths to different user nodes from the base station in the wireless network are computed by the base station, we call it centralized protocol (3DMA‐CS). A distributed routing (3DMA‐DS) protocol is implemented when respective routing path of each user node to the base station is computed by the user node. In both of these protocols, the user (base station) selects the relay node to forward packets in the direction of destination, from the set of its neighbours, which makes minimum angle with the reference line drawn from user (base station) to the base station (user), within its transmission range. The proposed protocols are free from looping problem and can solve the void node problem (VNP) of multihop wireless networks. Performance analysis of the proposed protocol is shown by calculating end‐to‐end throughput, average path length, end‐to‐end delay, and energy consumption of each routing path through extensive simulation under different network densities and transmission ranges.
Umweltwirkungen von Bauprodukten – Möglichkeiten und Grenzen beim Vergleich verschiedener Wandkonstruktionen
Authors: Walther Hartmut B. 
Published: December 2019

AbstractLife cycle assessments quantify the environmental impact of goods and services. Increasingly, their results should be used for variant comparisons in construction planning and procurement.
For the ecological assessment of wall building materials, this should not be limited to the assessment of the blocks, but the influence of insulation, plaster and mortar have to be taken into account as well. The considered wall should also fulfil predetermined properties such as a certain U‐value.The LCA data available today still do not permit any comparison of variants. For this, product‐specific life cycle assessments/environmental product declarations would have to exist on the basis of uniform background data. Because the latter are being constantly developed and there are hardly any product‐specific calculations, comparisons today are very inaccurate and subject to great uncertainties.

The walls were constructed with unfilled thermally insulating clay units with a thermal conductivity of λ = 0.09 W/(m · K).The current design rules for clay unit masonry according to DIN EN 1996‐1‐1/NA [5] are conservative compared to the presented test results for thermally insulating clay unit masonry.
Bee pollinator functional responses and functional effects in restored tropical forests
Authors: Montoya‐Pfeiffer Paula María , Rodrigues Ricardo R. , Alves dos Santos Isabel 
Published: December 2019

AbstractWild pollinators are necessary for ensuring plant reproduction, not only among crop fields but also remnant and restored ecosystems. Restoration activities should, therefore, lead to wild pollinator recovery, and thus be monitored to evaluate effects on pollinator diversity and functionality. We assessed bee pollinator functional responses in restoration plantings by creating functional groups (traits: body size, nesting location, sociality, and foraging strategy), comparing their abundance and diversity to that of other habitats (i.e., conserved and degraded primary forest fragments, anthropogenic wetlands, and sugarcane fields), and testing for an effect of source habitat (i.e., primary forest fragments) isolation. We analyzed functional effects on pollen transportation by identifying the pollen grains attached on the bodies of bees; creating plant functional groups with the identified species (traits: habit, successional class, geographic origin, and pollination mode); comparing their frequency, diversity, and interaction network structure among habitats; and searching for key interactions in network modules. In general, the abundance and diversity of bee communities and the frequency and diversity of the interacting plant species in restoration plantings were lower than those in primary forest fragments but higher than those in anthropogenic wetlands and sugarcane fields, suggesting that restoration plantings better enhance bee community recovery and functionality than other disturbed habitats. The interacting bees and plants were also negatively affected by habitat isolation, demonstrating the importance of primary forest fragments to supply bee populations to restored sites. The structure of interaction networks was little affected by habitat change and isolation, but the composition and diversity of functional groups varied significantly. There were more effects on larger bee species with more restricted nesting and floral requirements, and the woody species with which they interact most frequently. We identified key functional groups of bee pollinators that deserve priority for conservation because they play an important role in the pollen transportation of some the most relevant species in remnant forests and restoration plantings and also respond more negatively to habitat disturbances. Restoration efforts should include provisioning of nesting resources and management and conservation of primary forest remnant fragments that represent source habitats for them.
High mortality rates in a juvenile free‐ranging marine predator and links to dive and forage ability

Abstract

High juvenile mortality rates are typical of many long‐lived marine vertebrate predators. Insufficient development in dive and forage ability is considered a key driver of this. However, direct links to survival outcome are sparse, particularly in free‐ranging marine animals that may not return to land.

In this study, we conduct exploratory investigations toward early mortality in juvenile southern elephant seals Mirounga leonina. Twenty postweaning pups were equipped with (a) a new‐generation satellite relay data tag, capable of remotely transmitting fine‐scale behavioral movements from accelerometers, and (b) a location transmitting only tag (so that mortality events could be distinguished from device failures). Individuals were followed during their first trip at sea (until mortality or return to land). Two analyses were conducted. First, the behavioral movements and encountered environmental conditions of nonsurviving pups were individually compared to temporally concurrent observations from grouped survivors. Second, common causes of mortality were investigated using Cox's proportional hazard regression and penalized shrinkage techniques.

Nine individuals died (two females and seven males) and 11 survived (eight females and three males). All but one individual died before the return phase of their first trip at sea, and all but one were negatively buoyant. Causes of death were variable, although common factors included increased horizontal travel speeds and distances, decreased development in dive and forage ability, and habitat type visited (lower sea surface temperatures and decreased total [eddy] kinetic energy).

For long‐lived marine vertebrate predators, such as the southern elephant seal, the first few months of life following independence represent a critical period, when small deviations in behavior from the norm appear sufficient to increase mortality risk. Survival rates may subsequently be particularly vulnerable to changes in climate and environment, which will have concomitant consequences on the demography and dynamics of populations.
Global canopy rainfall interception loss derived from satellite earth observations
Authors: Zheng Chaolei , Jia Li 
Published: December 2019

AbstractInformation on global canopy rainfall interception loss is essential for understanding the dynamics of land surface processes and the water cycle. In addition, large uncertainty remains regarding the global variation in this factor. The development of satellite earth observations has provided a great opportunity for the estimation of global rainfall interception loss to reveal the spatiotemporal variations. In the current study, the analytical Gash model was adapted and applied to estimate global rainfall interception loss from 2001 to 2015 on the basis of satellite remote‐sensing products, for example, gross rainfall amount and rate and leaf area index. The Dalton‐type equation was adopted to estimate the wet canopy evaporation rate in the revised Gash model. The estimation on the basis of the Dalton‐type equation showed better agreement with the ground observations than the classical Penman–Monteith equation in terms of estimated rainfall interception loss and its ratio to gross rainfall. Large spatial variations in global rainfall interception loss were found, and high values appeared in the regions with dense vegetation cover and high gross rainfall amounts, for example, tropical rainforests, whereas high rainfall interception to gross rainfall ratios occurred in the regions with low rain rates and high vegetation cover. This study constitutes a significant step forward in understanding global hydrological cycle on the basis of earth observation products.
A decadal‐scale numerical model for wandering, cobble‐bedded rivers subject to disturbance

Published: December 2019

AbstractAlluvial rivers are composed of self‐formed channels which are sensitive to disturbances in their flow and sediment‐supply regimes. Regime changes commonly occur over decadal and longer timescales and can be caused by anthropogenic alterations such as dam construction and removal. Advances in numerical modeling have increased our ability to explore geomorphic adjustments over long timescales; however, many models designed to be run for decades or longer assume that banks are immovable or that channel width is constant. Since river channels often respond to disturbance by adjusting their geometry, this is a significant shortcoming. To investigate the impact of long‐term sediment supply alterations on channel geometry and stability, we have adapted MAST‐1D, a reach‐scale bed evolution model, to incorporate functions for bank erosion, vegetation encroachment, and local avulsions. The model is designed for medium‐large, coarse multithreaded rivers and can be run over long (decades–centuries) timescales. Bank erosion is a function of the mobility and transport capacity for structurally‐important grains which protect the bank toe. Vegetation growth is proportional to point bar width and occurs during conditions of low shear stress. Local avulsions occur when aggradation causes channel depth to drop below a threshold. We apply the model to the Elwha River in Washington, USA with the goal of investigating if and when the river recovers from dam emplacement and removal. The Elwha was dammed for nearly 100 years, and then two dams were removed, releasing a large pulse of sediment. We have modeled the set of reaches between the two dams. Our simulations suggest that channel response to dam emplacement occurs gradually over several decades but that the channel recovers to near pre‐dam conditions within about a decade following the removal. The dams leave a lasting legacy on the floodplain, which does not completely recover, even after two centuries. © 2019 John Wiley & Sons, Ltd.

Published: December 2019

AbstractNowadays, the quest of new radical precursors based on heteroatom complexes occupies an increasingly prominent position in contemporary research. Herein, we investigated the behavior and the limitations of hexa‐ or pentacoordinated organochlorosilanes and related pentacoordinated silyliums as new families of complexes for the generation of radicals under photocatalytic reductive conditions. Particularly, treatment of chlorophenylbis[N,S‐pyridine‐2‐thiolato(−)]silicon(IV) or the related silylium derivative with thefac‐Ir(ppy)3(5 mol‐%)/NEt3(1.5 equiv.) system under blue LEDs irradiation generates a thiopyridyl radical which can participate in the formation of a carbon−sulfur bond by reaction with an allylsulfone. Computational studies supported this experimental finding, and particularly by showing that homolytic fragmentation of C−Ts bond is favored over the fragmentation of thiopyridyl radical.

AbstractMagneto peristaltic flows of nanofluids play a key role in magnetic drug transport systems. Therefore, peristalsis of a nanofluid through a uniform porous medium under the influence of a uniform magnetic force is studied here. Ohmic heating and Hall aspects are incorporated in the analysis. Three distinct types of nanoparticles (ie, silver, alumina, and copper) have been used for theoretical analysis. A large wavelength and a small Reynolds number scheme are adopted in mathematical modeling. The dimensionless nonlinear system is solved using the well‐known perturbation method, and physical analysis is done via graphs. A comparison of different nanoparticles is also presented. It is noticed that an increase in the Hall effects nullifies the variations, which are due to an increment in the Hartman number. The temperature of the nanofluid can be reduced by increasing the permeability of the porous medium.

AbstractGlioma, like most cancers, possesses a unique bioenergetic state of aerobic glycolysis known as the Warburg effect, which is a dominant phenotype of most tumor cells. Glioma tumors exhibit high glycolytic metabolism with increased lactate production. Data derived from the gene expression profiling interactive analysis (GEPIA) database show that pyruvate dehydrogenase kinase 1 (PDK1) is significantly highly expressed in glioma tissues compared with corresponding normal tissues. PDK1 is a key enzyme in the transition of glycolysis to tricarboxylic acid cycle, via inactivating PDH and converting oxidative phosphorylation to Warburg effect, resulting in increment of lactate production. Silencing of PDK1 expression resulted in reduced lactate and ATP, accumulation of ROS, mitochondrial damage, decreased cell growth, and increased cell apoptosis. Aberrant expression of miR‐128 has been observed in many human malignancies. Mechanistically, we discover that overexpressed miR‐128‐3p disturbs the Warburg effect in glioma cells via reducing PDK1. Our experiments confirmed that the miR‐128‐3p/PDK1 axis played a pivotal role in cancer cell metabolism and growth. Collectively, these findings suggest that therapeutic strategies to modulate the Warburg effect, such as targeting of PDK1, might act as a potential therapeutic target for glioma treatment.

AbstractIn an attempt to obtain a model of copper(II) ion‐selective sensors, a new 1,8‐naphthalimide‐based fluorescence chemosensor,N‐allylamine‐4‐[(E)‐4‐(([2‐aminoethyl]imino)methyl) benzene‐1,3‐diol]‐1,8‐naphthalimide (NABN), was designed and synthesized. The sensor NABN is fully characterized by melting point analysis, fourier transform infrared spectra, Ultraviolet–visible (UV–vis) spectra, fluorescence spectra,1H NMR and13C NMR spectroscopy, and mass spectrometry. NABN showed an unrivaled sensing behavior and an ardent selectivity toward copper(II) ion over other competitive metal ions tested in solution (N,N‐Dimethylformamide (DMF)/Tris–HCl buffer, 1:1, v/v, pH = 7.2). The sensor showed a linear fluorescence quenching toward copper(II) ion in the range 0–50 μM, with a detection limit of 1.92 × 10−7M estimated. Job's method indicated the formation of a 2:1 coordinative mode of the sensor with copper(II) ion with a high threshold of binding constant of 4 × 1012 M−1. Combining the above results, the quenching response of NABN toward Cu(II) ions could be ascribed to the strong, intrinsic paramagnetic behavior of Cu(II).
