The research on the Culturing of Duckweed (Lemna minor) plants under different chicken manure concentrations in the laboratory was conducted to determine relative growth rate of duckweed and to determine the physicochemical parameters of the experimental water. The experimental design was based on an assumption that duckweed spores are contained in the bottom of flood plain stagnant pools. The sprouting of duckweed (Lemna minor) was monitored under media chicken manure concentrations of 5g per 10 litre for treatment one. Treatment two was 7.5g per 10 litre of water. Treatment three, 10g per 10 litre of water, treatment four, 12.5g per 10lit of water, and for treatment five 15g per 10 litre of water was used. 75 litre plastic bowls were used for this experiment. Each bowl were inoculated with 100 pods of duckweed. Water quality in tanks treated with chicken manure and inoculated with duckweed shows that there was no significant difference in water quality across the treatments (p>0.05). However, the pH varied over the weeks of experimentation with increase in pH being observed from an initial value of 7.92 to a final value of 10.25 in week 4. There was a high percentage increase of 45% in DO for T2 while all other treatments recorded declines in DO. Each treatment was replicated, giving a total of 12 experimental containers including the control treatment. To every plastic container 100g of wet soil that was collected was introduced along with 10 liters of domestic water supply. The various chicken manure levels were weighed and randomly assigned to the experimental containers in replicate. Under favorable climatic conditions and nutrient balance in growth media, Lemna minor can double its biomass within seven days. The plot of numerical abundance of duckweed stems in the culture media revealed that duckweed mean levels in T2 (M=213.8000) was more than other treatments with significant difference at P<0.05. T5 (M= 83.6000) was least, and Control (M= 95.0000), during the experiment.

Orissa is the fourth largest state in India covering an area of 15.57 m ha out of which the net sown area is 6.13 m ha. Out of 8 broad soil groups found in the state, red and laterite groups of soil occupy more than 75% of total cultivable area. Low productivity of crops in red and laterite soils are associated with deficiency of Ca, Mg, S, B and Mo (Mitra and Sahu, 1988). The DTPA extractable Zn also indicates that red and laterite soils of Orissa is deficient in available Zn and respondent to Zn application to rice crop (Anonymous, 2002; Mandal et al., 2009). Next to Zn, the deficiency of B is wide spread in many districts of the state as well as contrary (Sharma et al., 2006). Rice-Groundnut is the most prevailing cropping pattern in red and Lateritic soils of Orissa. In spite of recommended dose of NPK fertilizer, the farmers get low yield. A field experiments were carried out with rice-groundnut cropping systems in two successive cropping seasons each, to study the effect of S, B and Zn on grain yield, nutrient uptake and their accumulation. The experimental design included ten treatments, T1: control, T2 : S 40 kg/ha, T3 : B 1 kg/ha, T4 : Zn 5 kg/ha, T5 : FYM 5 t/ha, T6 : S+B, T7 : S+Zn, T8 : B+Zn, T9 : S+B+Zn and T10 : S+B+Zn+FYM replicated thrice in randomized block design. Integrated use of S + B + Zn with FYM was the ideal combination for rice-groundnut cropping system as it was more sustainable, recorded the highest yield and SYI value along with higher accumulation and uptake of nutrients. The results revealed that red and lateritic soils are poor in S and B need integrated use of S, B and Zn along with recommended dose of NPK for getting synergistic and best effect in rice-groundnut cropping system.

Published: November 2024

A study was conducted to analyze milk's marketed surplus and marketing efficiency in the Vishakhapatnam and Chittoor districts of Andhra Pradesh. The study randomly selected 80 dairy farmers from four villages in Chittoor and Vishakhapatnam districts. According to the study, average milk production and marketable surplus increase as herd size increases. The average marketed surplus is highest for the large size category (58.75 lit/day) followed by Medium (45.40 lit/day) and small size category (19.01 lit/day). Because of the lowest price spread and highest producer share in consumers' rupee, the most efficient marketing channel was producer-consumer (Channel-I), followed by producer-creameries-consumer (Channel-II). The study suggests that producers' choice of supply network influences their profitability.

AbstractHerein, persistent luminescence nanoparticles (PLNPs) and photosensitizer are integrated for cancer theranostics with high specificity and without the need of continuous illumination. Specifically, ZnGa1.996O4:Cr0.004 (PLNPs) and IR780 (photosensitizer) are encapsulated by a temperature‐responsive “wax‐seal” composed of oleic acid and hexadecanol. The seal prevents luminescence quenching and premature initiation of photodynamic therapy (PDT), until it is melted down by heat stimulus. After photothermal activation, the near‐infrared afterglow offered by PLNPs provides imaging with high signal‐to‐background ratio because of the absence of tissue autofluorescence, as well as continuously excited photosensitizer for reactive oxygen species generation. Such theranostic nanoplatform offers multimodal imaging–guided localized cancer PDT.

AbstractComposite films consisting of wrinkles on top of the elastomeric poly(dimethylsiloxane) film and a thin layer of silica particles embedded at the bottom is prepared as on‐demand mechanoresponsive smart windows. By carefully varying the wrinkle geometry, silica particle size, and stretching strain, different initial optical states and a large degree of optical transmittance change in the visible to near infrared range with a relatively small strain (as small as 10%) is achieved. The 10% pre‐strain sample has shallow wrinkles with a low amplitude and shows moderate transmittance (60.5%) initially and the highest transmittance of 86.4% at 550 nm when stretched at the pre‐strain level. Stretching beyond the pre‐strain level leads to a drastic decrease of the transmittance at 550 nm, 39.7% and 70.8% with an additional 10% and 30% strain, respectively. The large drop of optical transmittance is the result of combined effects from the formation of secondary wrinkles and nanovoids generated around the particles. The 20% pre‐strain sample has wrinkles with a moderate amplitude, showing 36.9% transmittance in the initial state, and the highest transmittance of 71.5% at 550 nm when stretched to the pre‐strain level. Further stretching leads to increased opacity similar to that seen from the 10% pre‐strain sample.

Published: September 2018

AbstractSpectrally selective thermal emission is in high demand for thermophotovoltaics, radiative cooling, and infrared sensing applications. Spectral control of the emissivity is historically achieved by choosing the material with suitable infrared properties. The recent advancements in nanofabrication techniques that lead to enhanced light–matter interactions enable optical properties like infrared emissivity that are not naturally available. In this study, thermal emitters based on nanometer‐thick dielectrics on field‐enhancement surfaces as optical security features are proposed. Such a function is achieved by generating patterns by ultrathin dielectrics that are transparent in the visible and exhibit strong infrared absorption in the spectral range of thermal cameras. The invisible patterns are then revealed by thermal imaging. The field‐enhancement surfaces enhance the emissivity of the patterns, in turn reduce the minimum temperature to detect the thermal emission down to ≈30 °C from >150 °C to exploit ubiquitous heat sources like the human body. The study provides a framework for the use of thermal emitters as optical security features and demonstrates applications on rigid and flexible substrates.

AbstractNature‐inspired self‐assembled peptide‐based nanoscale materials are of great interest for biomedical applications. Here, ionophore gramicidin‐inspired designed nanoscale materials for drug delivery and cancer nanotherapeutics are reported. The length dependent formation of diverse nanoarchitectures by experimental and computational studies from gramicidin‐inspired sequences is explored and their therapeutic potential is evaluated. Mechanistic studies revealed that gramicidin A (gA) and gramicidin‐inspired octapeptide (LD8) induce cytotoxic effects, mitochondrial depolarization, and apoptotic cell death against metastatic breast cancer cell line MDA‐MB‐231. Doxorubicin loaded LD8 peptide (LD8‐Dox‐NP) and doxorubicin loaded gramicidin (gA‐Dox‐NP) show cytotoxicity determined by MTT assay and apoptosis as evidenced by DNA fragmentation study and Western blot analysis of poly (ADP‐ribose) polymerase (PARP) expression and cleavage. gA‐Dox‐NP and LD8‐Dox‐NP treated MDA‐MB‐231 cells show upregulation of tumor suppressor protein p53, which can inhibit cell proliferation. Interestingly, cell cycle analysis suggests that gA‐Dox‐NP and LD8‐Dox‐NP induce S and G2 phase cell cycle arrest, respectively. These data establish gA and LD8 peptide as new potential anticancer therapeutics against metastatic breast cancer and suggest that gA‐Dox‐NP and LD8‐Dox‐NP can be potentially used as two‐in‐one nanomedicine for treating breast cancer.

Published: September 2018

AbstractAmorphous small‐molecule hole‐transporting materials are commonly used in organic light‐emitting diodes and perovskite solar cells. Characterization of their main functionality, hole transport, has been complicated by the presence of large contact barriers. Using a recently developed technique to establish Ohmic hole contacts, the bulk hole transport in a series of molecules with a broad range of ionization energies is investigated. The measured charge‐carrier mobility dependence on charge concentration, electric field, and temperature is used to extract the energetic disorder and molecular site spacing. Excellent agreement of these parameters as well as ionization energies with multiscale simulations paves the way to predictive charge‐transport simulations from the molecular level.

AbstractA series of arylallenes react with HB(C6F5)2 in a 2:1 molar ratio to give the tail‐to‐tail 1,6‐diaryl‐2‐boryl‐hexa‐1,5‐diene coupling products. The reaction of the phenylallene substrate with HB(C6F5)2 was shown to initially give the 2‐boryl‐3,4‐diphenyl‐1,5‐hexadiene head‐to‐head coupling product which then rearranged, by a thermally induced Cope rearrangement, into the final product.

AbstractCorrosion of stone by acid rain and deterioration from biofilms are global problems for industrial and residential buildings as well as cultural heritage, such as statues or historic buildings. Herein we show how typical building stones can be protected from corrosion (“weathering”) and biofilm formation (“biodeterioration”) by application of thin films of polyoxometalate‐based ionic liquids (POM‐ILs). Stone samples are coated with hydrophobic, acid resistant POM‐ILs featuring biocidal properties. Exposure of the samples to simulated acid rain showed negligible corrosion compared to the significant deterioration of unprotected samples; in addition the biocidal properties of the POM‐ILs suppress the formation of biofilms on coated stone slabs. A new class of modular molecular materials for protecting stones can now be developed for use in construction, environmental protection, and cultural heritage preservation.
A sequential trial effect based on the motor interference effect from dangerous objects: An ERP study

Published: September 2018

AbstractIntroductionThis study aims to investigate whether processing a prepared response toward a dangerous object in a previous trial influences subsequent trial processing.MethodsThe design manipulated the Go/NoGo factor of the current trial, the target dangerousness of the previous trial and that of the current trial.ResultsIn current Go trials, the behavioral results revealed a classical motor interference effect in trials that were preceded by a safe trial (a longer reaction time (RT) and a larger error rate for the previous safe and current dangerous (sD) condition than for the previous safe and current safe (sS) condition). However, the motor interference effect diminished in trials that were preceded by a dangerous trial (insignificant differences in the mean RTs and error rates between the previous dangerous and current dangerous (dD) condition and the previous dangerous and current safe (dS) condition). The event‐related potential (ERP) results identified more positive P2 and parietal P3 amplitudes (indicating attentional resource allocation) for the dD condition than for the dS condition. However, the P2 and parietal P3 amplitudes of the sD condition did not significantly differ from those of the sS condition.DiscussionsThese results support the hypothesis that the avoidance motivation elicited by a dangerous target in a previous trial may indicate a dangerous situation, which leads to recruitment of more attentional resources allocated to the subsequent dangerous trial. Therefore, RTs are improved and errors are reduced in the consecutive dangerous condition, subsequently decreasing the motor interference effect in trials preceded by a dangerous trial compared with trials preceded by a safe trial. However, analysis of current NoGo trials revealed that none of the main effects or interactions reached significance in both the behavioral and ERP results, indicating that the hypothesis holds true only if the prepared response needs to be executed.
Linking green customer and supplier integration with green innovation performance: The role of internal integration
Authors: Du Longzheng , Zhang Zhenglin , Feng Taiwen 
Published: September 2018

AbstractAlthough green customer and supplier integration have gained much attention, how it affects green innovation performance is still unclear. This study examines the direct and interaction effects of green customer and supplier integration on green innovation performance and the moderating effect of internal integration, using data from 176 Chinese manufacturing firms. The results reveal that green customer integration, green supplier integration, and their interaction are all positively related to green innovation performance. In addition, internal integration moderates the relationship between green customer integration and green innovation performance, but does not moderate the relationship between green supplier integration and green innovation performance. Further analysis indicate that the effects of interaction term on green innovation performance and the moderating effects of internal integration on the relationship between green supplier integration and green innovation performance are significantly different across different firm sizes, providing useful insights for firms. This study provides novel insights for making environmental policies.
Environmental innovation inertia: Analyzing the business circumstances for environmental process and product innovations
Authors: Choi Hyundo , Yi Donggyu 
Published: September 2018

AbstractWe categorize the environmental innovations used in the environmental management and innovation management literature into two types: environmental process and product innovations. By using objective measurements of internal and external business circumstances from a large‐scale survey of manufacturing firms in Korea, we investigate whether firms delay adoption of specific environmental innovations and if so how to overcome the passive nature of environmental innovation activities. The main findings are as follows. Both low operational performance and high export intensity are likely to lead to environmental process innovations. On the contrary, they do not play a significant role in increasing environmental product innovations. Instead, environmental product innovations take place under normative pressure. These results contribute to the “it pays to be green” and true sustainability discussion by examining the business environmental fit of a focal firm—either with environmental process innovations or with environmental product innovations.
Buyer–supplier collaboration in green practices: The driving effects from stakeholders
Authors: Yen Yu‐Xiang 
Published: September 2018

AbstractGreen and environmental practices are considered critical to enhancing firm innovation and performance. Previous research has not fully explained how and why buyers collaborate with suppliers in green practices. This study aimed to verify the driving effects of stakeholders and the underlying mechanism in buyer–supplier collaboration. Questionnaires were used to collect empirical data from selected purchasing managers in listed Taiwanese electronics firms. Structural equation modeling was used to analyze the collected data and proposed model. Customer pressure and top management commitment are found to have a positive influence on buyer–supplier collaboration. Competitor pressure and regulatory pressure indirectly affect buyer–supplier collaboration through the mediating effects of customer pressure and top management commitment. However, green investment pressure does not significantly influence top management commitment and buyer–supplier collaboration. The results suggest that customers can leverage the pressure exerted by competing suppliers by bargaining with their current suppliers to improve collaboration with second‐tier suppliers.

Published: September 2018

AbstractIn this paper, we present the development of an opinion‐mining module. The development of the module consisted of creating an emotion tagged dataset of opinions; implementing an opinion mining module that processes sentences about computer programming, predicting or recognizing their polarity (positive/negative) and their type of emotion (frustrated, bored, excited, engagement, and neutral); and integrating the previous module in an intelligent learning environment. We evaluated the corpus, the accuracy of text polarity, and emotion recognition. The results with respect to polarity are promising (88.26%), however, the results in the detection of emotions are still low (60.0%). The reasons which likely explain these outcomes include a relatively small (7,777 records) and unbalanced corpus.

AbstractHerein the preparative (1 g scale), stereoselective syntheses of various alkyl‐substituted γ‐butyrolactone fragrances 1 is described. The α,β‐unsaturated γ‐keto esters 2 as starting materials were synthesized by a Horner‐Wadsworth‐Emmons reaction and are further reduced by an ene reductase and alcohol dehydrogenase in a one‐pot enzyme cascade to nine desired γ‐butyrolactones 1, among them whisky (1 c) and cognac lactone (1 d). The products 1 were obtained in moderate to good yields and very good diastereoselectivities. Furthermore, the position of a nBu‐substituent was permutated to study the effect on the enzyme cascade.

Published: September 2018

AbstractLayer‐structured SnS2 powders with plate‐like and flower‐like morphologies have been successfully synthesized through a facile hydrothermal method with different sources of sulfur. Their potential application as cathode catalysts of rechargeable Li−O2 batteries were electrochemically evaluated and analyzed with diverse physicochemical techniques. The results reveal that both SnS2 materials are capable of catalyzing oxygen reduction reaction as well as oxygen evolution reaction in the cathode of Li−O2 batteries, while the plate‐like ones perform much better. Moreover, the performance of SnS2 is also comparatively discussed with the opponent of tin oxides to identify the superiority of transition metal sulfides to transition metal oxides as cathode catalysts of Li−O2 batteries.
