ABSTRACT
The limited fertile land and increasing flood intensity as a result of global climate changes become serious constraints in the sustainability of national rice production. Improvement of rice varieties, especially for rice cultivation in swampy area is necessary. The objective of this research were to evaluate responses and productivity of rice genotypes to stagnant flooding stress which occurs on swampy area. A total of 22 genotypes had been tested, included Tapus, IR42, and IR64 as check varieties. Water level at stagnant flooding environment was 50-60 cm and  started from 35 days after planting until harvest. Research was conducted in wet season of 2011/2012 at Babakan Experimental Farm, Bogor Agricultural University. The experiment used randomized block design with three replicates. The results showed that stagnant flooding stress caused an increase in plant height, flowering and maturity date, number of unfilled grain, and stem elongation ability. On the other hand, the number of productive tiller and the number of filled grain decreased. The number of filled grain positively correlated with grain yield (r = 0.74**), but stem elongation ability didn’t have strong correlation with grain yield (r = -0.29). Genotypes IPB107-F-5-1-1 and IPB107-F-82-2-1 showed the highest productivity, 5.47 ton ha-1 and 5.80 ton ha-1,, respectively, at which productivity decreased up to 20% compared to optimum condition.

Oil palm is one of the important plantation crops in the plantation sector. Increased oil palm plantation area causes the need for the availability of oil palm seedlings in large quantities. Good quality oil palm seedlings were obtained through intensive maintenance especially fertilization. Fertilizers needed for the growth of oil palm seedlings include calcium and magnesium fertilizers. The objective of this experiment was to determine the optimum rates of calcium and magnesium fertilizer for oil palm seedling (Elaeis guineensis Jacq.). This experiment was conducted at Cikabayan Experimental Station, IPB Darmaga, Bogor, from December 2011 to November 2012. The experimental design used was factorial randomized block design with three replications. The first factor was Ca fertilizer rates i.e., 0, 5, 10,  and  20 g CaCO3 plant-1. The second factor was Mg fertilizer rates, i.e., 0, 24, 48,  and 96 g MgSO4  plant-1. The results showed that calcium affected stomatal density, whereas magnesium fertilizer affected morphological and physiological variables (stomatal density and chlorophyll content) of oil palm seedling. Based on the plant height and stem diameter, the recommended rate of magnesium fertilizer for 8 months oil palm seedlings in the main nursery was 58 g plant-1. This total rate should be applied at different amount every month from 1-8 month, at 2.0, 2.0, 8.0, 9.3, 8.8, 9.3, 9.4 and 9.3 g MgSO4 plants-1, respectively. The optimum rate of calcium fertilizer was not able to be determined in this research.

ABSTRACT

Tidal swamp lands containing acid sulphate is easily become idle land, which can be fixed by reducing oxidation process of pyrite (FeS2). The pyrite oxidation causes disturbance on the growth and yield of rice plant. An experiment was conducted by means soil leaching in order to reduce accumulation of pyrites. The research had been conducted in Simpang Jaya village, Barito Kuala District in 2012 using a split plot design with three replications. As the main plot was leaching, and no leaching treatment, while as the subplot was soil tillage, i.e., 1) control, 2) weeds cleared without tillage, 3) soil tillage at a depth of 15 cm, and 4) soil tillage at a depth of 30 cm. The results showed that the leaching treatment combined with tillage at a depth of 15 cm or 30 cm increased the number of rice tillers, shoot dry weight, and number of panicles per hill, and number of seeds per hill, thus the leaching treatment was able to increase rice production.

ABSTRACT

Black cumin (Nigella sativa L.) is a native medicinal plant to subtropical West Asia and the Mediterranean regions. So far, information regarding black cumin fertilization is still limited. The objectives of this study was to obtain the optimum rate of N and P fertilizer in order to promote the growth and production of black cumin under tropical climates. This research was conducted at Manoko Experimental Station, Lembang, West Java from October 2012 to January 2013. The research was arranged in randomized complete block design with two factors and three replications. The first factor was four rates of N fertilizer (0, 40, 80, 120 kg N ha-1), and the second factor was four rates of P fertilizer (0, 40, 80, 120 kg P2O5 ha-1). The results showed that application of N and P fertilizers increased plant height, leaf number, branch number, leaf area, leaf area index, relative growth rate, net assimilation rate, plant dry weight, number of capsule per plant, number of seed per capsule, seed weight per plant, and weight of 1,000 seeds. Moreover, growth and production of black cumin still increased at the highest rates of N and P fertilizers, therefore, it is necessary to study for N and K at higher rates in order to obtain optimum production rate.

ABSTRACT

The accuracy of fertilizer dosage for one-year-old oil palm plants is very important. The objective of the research was to determine the optimum rates of Nitrogen and Phosphorus fertilizers for young oil palm. The experiment was conducted at IPB-Cargill Teaching Farm of Oil Palm at Jonggol, from March 2013-March 2014. This study consisted of two separate experiments namely (1) Optimizing Nitrogen and (2) Optimizing Phosphorus. Both experiments used randomized block design with one factor and three replications. The treatments were five rates of nitrogen or phosphorus (0, 135, 270, 405, 540 g N per plant; 0, 135, 270, 405, 540 g P2O5 per plant). The results showed that nitrogen fertilizer rates increased height linearly at 10 month after treatment (MAT) and quadratically at 12 MAT. Stem girth, frond production and leaf area of 9th frond increased quadratically with N rates (9, 10, 12 MAT). Nitrogen fertilizer quadratically increased leaf chlorophyll content (12 MAT), but did not significantly affected leaf-N content. Phosphorus fertilizer increased palm height linearly (9, 10 MAT) and quadratically (12 MAT). Phosphorus linearly increased stem girth (12 MAT) and quadratically (9, 10 MAT). Frond production was quadratically increased with phosphorus rates (9, 10, 12 MAT). Phosphorus linearly increased leaf area of 9th frond (9 MAT) and quadratically (12 MAT). The optimum rates of nitrogen and phosphorus fertilizers for one year old plant was 382 g N and 331 g P2O5 per plant, respectively.

ABSTRACT

Bambara groundnut can be cultivated in marginal land, however, its productivity is still low. In order to increase productivity, high quality seed must be used. The objective of the experiment was to evaluate the effects of seed invigoration using matriconditioning plus Rhizobium sp. and fungicide and reduction of N fertilizer on plant growth, yield, and quality of bambara groundnut seed. The experiment was conducted at Experimental Station in Cikarawang, green house in Cikabayan, and Seed Health Laboratory, Bogor Agricultural University from June 2013 until March 2014. This experiment was arranged in a split plot design according to completely randomized block design. The first factor was N fertilizer. Four levels of N fertilizer used were 0, 15.35, 30.7, 46.04, and 61.39 kg N ha-1. The second factor was seed invigoration. Seed invigoration consisted of without invigoration treatment (untreated), matriconditioning plus Rhizobium sp. and fungicide, matriconditioning plus Rhizobium sp., and matriconditioning plus fungicide. Result of the experiment indicated that matriconditoning plus Rhizobium sp. and fungicide improved plant growth (number of leaves, number of stem, nodule dry weight, root dry weight, and leaf dry weight), yield (weight of seed), and seed vigor (index of vigor). Matriconditioning plus Fungicide treatments significantly decreased the infection level of diseases on seed. Fertilizer application at the rate of 30.7 kg N ha-1 (half of optimum dose) was recommended because it showed the best result in pod fresh weight and dry weight, and seed weight.

ABSTRACT

Somatic embryo induction medium was reported to be genotype dependent for soybean. This study was aimed to obtain the optimum medium for embryo somatic induction and proliferation, and to regenerate somatic embryo of five soybean genotypes. Five soybean genotypes (Tanggamus, Anjasmoro, Yellow Biloxi, CG-22-10, and SP-10-4) were used in this study. The research was divided into four steps: (1) embryogenic callus induction of  five soybean genotypes, (2) embryogenic callus proliferation of five soybean genotypes, (3) optimation of embryo somatic induction on five soybean genotypes and (4) embryo somatic regeneration of five soybean genotypes. The induction experiment showed that based on number of embryogenic callus, the best somatic embryo-induction medium was 3% sucrose+ NAA 5 mg L-1+2,4-D 5 mg L-1+ Vitamin B5. Embryogenic callus number for each genotype tested was increased on proliferation media of 3% sukrosa + 2,4-D 5 mg L-1 + NAA 5 mg L-1+ Vit B5, and Yellow Biloxi gave the highest number of proliferated somatic embryos compared to other genotypes. Increasing number of globular somatic embryo of all genotypes was obtained from the optimation of somatic embryo induction media being used, and Tanggamus genotype gave the highest number of globular somatic embryo which followed by Yellow Biloxi genotype. Tanggamus and Yellow Biloxi genotypes were also successfully formed the four steps of somatic embryos (globular, heart, torpedo, and cotyledonary stages), but in regeneration medium of MS0 and media MS + sukrosa 10 g L-1 + GA3 2 mg L-1 + BAP 4 mg L-1 + Vit B5 only Tanggamus genotype was regenerated into plantlet.

ABSTRACT

An effective and efficient in vitro propagation system has important roles in preparing and producing high quality-seedlings of Dendrobium for commercial scale. The objective of this research was to establish an effective and efficient embryogenic callus (EC) proliferation method using bioreactor system and regeneration EC into plantlet for producing high quality seedlings of Dendrobium Indonesia Raya ‘Ina’. Differences in callus densities (5, 10, 15, and 20 g callus in 250 mL medium), aeration levels (2.5, 5.0, and 10.0 O2 volume  per  medium volume per minute; vvm), and regeneration media half-strength MS and 2 g L-1 NPK (32:10:10) combinated by 0.00, 0.05 mg L-1 BA, 150  mL L-1 coconut water and their combinations were tested in this experiment. The experiments were arranged using randomized completely block design (RCBD) with three replications for EC proliferation and randomized completely desaign (RBD) for EC regeneration. The results showed that combination of  aeration at 2.5 vvm and 10 g of EC was the most suitable aeration level and callus density for proliferation of EC in the 500 ml airlift bioreactor with 6.85 multiplication rate, 92.5% EC formation, and malformed callus morphology as low as 6.1%. The highest somatic embryos (SEs) formation was 87.7% with 44.5 SEs per clump and 92.1% SEs germination with 41.0 germinated-SEs per clump, 85.1% normal germinated-SEs, and whereas the best performance of plantlet was obtained from 1/2 MS + 0.05 mg L-1 BA semi solid medium. Plantlets were successfully acclimatized using Cycas rumphii medium with high survival rate (91.6%).

„Involvierte“ Väter zwischen Beruf und Familie. Zur Re/Produktion von Männlichkeiten in paarinternen Aushandlungen
Authors: Peukert Almut
Published: April 2017

Starting from the hypothesis discussed in research on masculinities and fathering that ‘involved’ fathering is incompatible with hegemonic masculinity, this paper examines continuity and change in interrelating work and family life by German fathers. Within the sociological frame of interaction theory on un/doing masculinity I focused on the production and presentation of gender differences and the hierarchizing demarcation against femininity and non-hegemonic masculinities within the couple. Based on 27 qualitative couples’ and individual interviews, three forms of re/production of masculinity were constructed and discussed along the dimensions of vocational/career concepts, financial care of the family, and parental leave arrangements within the couple. The results show that the re/production of masculinities within negotiations of the couples regarding paid and family work are fragile, challenged, or episodically undone. This implies that in addition to welfare state policies and work organizations, the negotiations within the couple about their division of paid and unpaid work have significant consequences for the un/equality between the parents.

Zusammenfassung

Ausgehend von der in der Männlichkeitsforschung diskutierten These, ‚involvierte‘ Väterlichkeit stehe im Widerspruch zum Leitbild erwerbszentrierter hegemonialer Männlichkeit, werden im vorliegenden Beitrag Kontinuitäten und Wandel in der Relationierung von Erwerbs- und Familienarbeit bei Vätern untersucht. Mit dem interaktionstheoretischen Ansatz zu ‚un/doing masculinity‘ liegt der Fokus auf der Her- und Darstellung von Geschlechterdifferenzen sowie der hierarchisierenden Abgrenzung zu Weiblichkeiten und nicht-hegemonialer Männlichkeiten im Paarkontext. Anhand von 27 qualitativen Paar- und Einzelinterviews werden – entlang der Dimensionen Berufs-/Karrierekonzept, finanzielle Versorgung der Familie und Elternzeitarrangement – drei Re/Produktionsformen erwerbszentrierter hegemonialer Männlichkeit rekonstruiert und diskutiert. Im Ergebnis zeigt sich, dass die Re/Produktion von Männlichkeiten in paarinternen Aushandlungen zu Erwerbs- und Familienarbeit fragil, herausgefordert oder episodisch ausgesetzt wird. Dies impliziert, dass auch die Aushandlungen auf der Paarebene zur Relationierung von Erwerbs- und Familienarbeit, neben wohlfahrtsstaatlichen Rahmungen und Arbeitsorganisationen, signifikante un/gleichheitsrelevante Folgen haben.

Authors: Umer Muhammad , Abid Muhammad
Published: April 2017

The global trade economy is worth $12 trillion per annum with $3 trillion dedicated to materials only. A significant amount of almost 75% of global waste is produced during materials processing and after their use. While considering materials, plastic in specific did modernize the way product manufacturing was done in earlier times. Keeping in view the significance of plastic and its ever embryonic trend in terms of its end-user demand, results of a detailed study based on extensive surveys from six different industrial estates are presented highlighting economy practices adopted at industry and societal level, sources of raw material, manufacturing practices, organizational size, demographical product distribution, variety of plastic types and products, plastic waste reprocessing and management, analysis of plastic production in Pakistan in addition to the global trends. It is concluded that in Pakistan plastic industry still mostly follow the linear economy practices at large. However, a need for circular economy practices implementations is recommended based on its existence at some scales to address the challenges ahead.
Influence of Various Dispersion Coefficients on Contaminant Migration in a Fracture-matrix System with Skin Formation
Authors: Natarajan N.
Published: April 2017

Subsurface contamination due to transient migration of chemicals through weathered fractures is a serious problem in hard rock terrains. In this paper, a numerical model has been used to analyse the effect of various dispersion coefficients on the movement of contaminants in a fracture-matrix system with skin formation. A constant continuous source of contaminants is considered at the inlet of a set of parallel fractures and an implicit finite difference technique has been used to solve the model. The transport of contaminants with constant dispersion coefficients were compared with those subjected to distance and time dependent dispersion. Sensitivity analysis has been conducted to study the effect of different fluid velocities, fracture-skin porosities, fracture-skin diffusion coefficients, fracture aperture, retardation factors, and dispersivity-distance ratio on solute transport mechanism within the system. Results suggest that the solute mass retained in the fracture is higher when time-dependent dispersion coefficients are used which may be due to seasonal conditioning of the rocks. When constant dispersion coefficient is considered, the reduction in the solute mass with increment in the fracture-skin porosity is gradual unlike other cases.The solute mass retained in the fracture increases with increase in dispersivity-distance ratio for time-dependent dispersion coefficients.

Published: April 2017

This descriptive cross-sectional study was conducted to explore the status of professionalism regarding knowledge, attitude and practice among intern doctors of different medical college Hospitals in Bangladesh. Study period was July 2015 June 2016.Sample size was 300 and convenient sampling technique was adopted. Study was carried out among all Bangladeshi intern doctors of 4 governments and 2 non-governments selected medical college Hospitals of Dhaka and outside Dhaka. Total 300 intern doctors responded to a self-administered questionnaire. Male female ratio was almost 1:1. Concept of professionalism and level of knowledge regarding its various aspects are not satisfactory in large extends. But attitude towards most of the major principles of professionalism are as much as positive like USA and UK physicians. However, regarding honesty with patients, one statement like physicians should disclose all significant medical errors to affected patients and/or guardians, only 36.9% agreed with this. Similarly, only 43% agreed the statement of re-certification examination to maintain professional competence. Regarding attitude and practice of major attributes & responsibilities of professionalism there is no significant difference (p>0.05) between male and female intern doctors working in different medical college hospitals; but regarding practice there is a significant difference (p<0.05) among intern doctors working in government and non-government hospitals.

This paper tests and confirms the cross-cultural equivalence of the Servant Leadership Survey (SLS) in eight countries and languages: The Netherlands, Portugal, Germany, Iceland, Italy, Spain, Turkey and Finland. A composite sample consisting of 5201 respondents from eight countries that all filled out the SLS was used. A three-step approach was adopted to test configural invariance, measurement equivalence, and structural equivalence. For the full 30-item version of the SLS, configural invariance and partial measurement equivalence were confirmed. Implications of these results for the use of the SLS within cross-cultural studies are discussed.

Published: April 2017

Motor imagery EEG (MI-EEG), which reflects one’s active movement intention, has attracted increasing attention in rehabilitation therapy, and accurate and fast feature extraction is the key problem to successful applications. Based on wavelet packet decomposition (WPD) and SE-isomap, an adaptive feature extraction method is proposed in this paper. The MI-EEG is preprocessed to determine a more effective time interval through average power spectrum analysis. WPD is then applied to the selected segment of MI-EEG, and the subject-based optimal wavelet packets (OWPs) with top mean variance difference are obtained autonomously. The OWP coefficients are further used to calculate the time-frequency features statistically and acquire the nonlinear manifold structure features, as well as the explicit nonlinear mapping, through SE-isomap. The hybrid features are obtained in a serial fusion way and evaluated by a k-nearest neighbor (KNN) classifier. The extensive experiments are conducted on a publicly available dataset, and the experiment results of 10-fold cross-validation show that the proposed method yields relatively higher classification accuracy and computation efficiency simultaneously compared with the commonly-used linear and nonlinear approaches.

Published: April 2017

Long term evolution-advanced (LTE-A) system introduces carrier aggregation (CA) technique to improve the user throughput by aggregating multiple component carriers (CCs). Previous research works related to downlink radio resource allocation with carrier aggregation have not considered the delay factor and the error probability. Therefore, the previous methods are unable to provide better quality of service (QoS) compared to the LTE-A standard. This paper considers the radio resource management problem by zooming into the head of line delay, probability of packet loss, and the delay threshold for different types of data. In doing this, several constraints are imposed following the specifications of LTE-A system. Hence, an improved method is developed in this study to enhance the system throughput and to maintain the computational complexity. Extensive simulations were carried out with other well-known methods to verify the overall performance of the proposed method. The result obtained indicates that the proposed method outperforms the previous methods in the measurement of average user throughput, average cell throughput, fairness index, and spectral efficiency.
Bi-Level Programming Approach for the Optimal Allocation of Energy Storage Systems in Distribution Networks
Authors: Shi Nian , Luo Yi
Published: April 2017

Low-CO2-emission wind generation can alleviate the world energy crisis, but intermittent wind generation influences the reliability of power systems. Energy storage might smooth the wind power fluctuations and effectively improve system reliability. The contribution of energy storage to system reliability cannot be comprehensively assessed by the installed capacity of energy storage. The primary goal of this paper is to investigate the impact of the installed location and capacity of energy storage on power system reliability. Based on a bi-level programming approach, this paper presents a bi-level energy storage programming configuration model for energy storage capacity and location configuration. For upper-level optimization, a depth search method is utilized to obtain the optimal installed location of energy storage. For the lower-level optimization, the optimal capacity of energy storage is solved to meet the system reliability requirements. The influence of the contribution of energy storage location to system reliability is analyzed. The proposed model and method are demonstrated using the RBTS-Bus6 System and Nanao (NA) island distribution system in China. The results show the effectiveness and practicability of the proposed model and method.

Two rare sulphate ellagic acid derivatives were isolated from the rhizome of Geum rivale L. in three simple steps. Their structures were identified by comprehensive NMR studies (1H NMR, 13C NMR, 1H-1H COSY, HMBC, HSQC) as 3,3′-dimethoxy-4-sulphoxyellagic acid potassium salt (1) and 3,3′,4′-trimethoxy-4-sulphoxyellagic acid potassium salt (2). Subsequently, a new precise (RSD < 2.6%), accurate (recoveries in the range of 96.5–98.7%), and sensitive (LODs in the range of 0.15–0.16 μg/mL) HPLC-PDA procedure was developed for the simultaneous quantification of compounds 1 and 2 in plant material. The rhizome of G. rivale proved to be a good source of both compounds, with the content of 2.94 ± 0.03 and 5.45 ± 0.03 mg/g dw respectively, whereas at most, trace amounts were detected in related plant materials (aerial parts of G. rivale, rhizome and aerial parts of G. urbanum). The cytotoxicity of isolated compounds tested on human leukaemia (promyelocytic HL-60 and lymphoblastic NALM-6) and melanoma (WM 115) cell lines with IC50 values in the range of 306.4–473.8 μM was demonstrated to be lower than that of ellagic acid (IC50 = 62.3–300.6 μM).

Published: April 2017

The research goal of this paper is to identify major academic branches and to detect research trends in design research using text mining techniques. In this paper, the information about scientific literature in design research isprocessed. A combination of clustering and bibliometric analysis led to shaping four academic branches and summarizing each academic branch. Then, research trends and the evolution for each academic branch are explored. We perform a two-dimensional text mining approach, including bibliometric and network analysis, in order to detect trends of major academic branches. Specifically, the bibliometric characterization aims to assess design research area outputs, while the network analysis intends to reveal research trends in each academic branch of design research and the evolution of core research themes.

Published: April 2017

Hydrophilic ceramic membranes (tubular and planar) made of TiO2 and Al2O3 were efficiently modified with non-fluorinated hydrophobic grafting molecules. As a result of condensation reaction between hydroxyl groups on the membrane and reactive groups of modifiers, the hydrophobic surfaces were obtained. Ceramic materials were chemically modified using three various non-fluorinated grafting agents. In the present work, the influence of grafting time and type of grafting molecule on the modification efficiency was evaluated. The changes of physicochemical properties of obtained hydrophobic surfaces were determined by measuring the contact angle (CA), roughness (RMS), and surface free energy (SFE). The modified surfaces were characterized by contact angle in the range of 111–132°. Moreover, hydrophobic tubular membranes were utilized in air-gap membrane distillation to desalination of sodium chloride aqueous solutions. The observed permeate fluxes were in the range of 0.7–4.8 kg·m−2·h−1 for tests with pure water. The values of permeate fluxes for membranes in contact with NaCl solutions were smaller, within the range of 0.4–2.8 kg·m−2·h−1. The retention of NaCl in AGMD process using hydrophobized ceramic membranes was close to unity for all investigated membranes.

This research include, to focus on the variation in the thickness of the liquid film in a porous space. The self-similarity variables have been applied to convert the modelled equations into a set of non-linear coupled differential equations. These non-linear differential equations have been treated through an analytical technique known as Homotopy Analysis Method (HAM). The effect of physical non-dimensional parameters like, Eckert Number, Prandtl Number, Porosity Parameter, Brownian Motion Parameter, Unsteadiness Parameter, Schmidt Number, Thermophoresis Parameter, Dimensionless Film Thickness, and Williamson Fluid Constant on the liquid film size are investigated and conferred in this endeavor. The obtained results through HAM are authenticated, from its comparison with numerical (ND-Solve Method). The graphical comparison of these two methods is elaborated. The numerical comparison with absolute errors are also been shown in the tables. The physical and numerical results using h curves for the residuals of the velocity, temperature and concentration profiles are obtained

With the increase of urban population and electricity demand, in order to provide sufficient power to residents, distribution transformers are getting closer to residential buildings, and are even directly placed on the first floor or the basement of buildings due to space limitations. The vibration and noise with low frequency of mainly 50–250 Hz generated by the distribution transformers spread to rooms through beams, bricks, walls and other building structures, which inevitably damages the living environment. In this paper, through focusing on the frame of buildings, simulation models of the indoor distribution transformer vibrating in the structure field are built, including a two-layer model and a six-layer model. This paper simulates and analyzes the vibration response of the structural system, studies the propagation laws of the structure-borne sound caused by the transformer and quantitatively analyzes the attenuation characteristics of the vibration. Finally the prevention method of the structure-borne noise, called vibration isolation, is introduced and analyzed by the field test to evaluate the noise reduction effect.

In this work, aluminum oxide films with excellent passivation effects were prepared on the rear-side surface of passivated emitter and rear cells (PERCs) using a self-developed spatial atomic layer deposition system. Various rear-side surface morphologies were obtained through different etching treatments. We compared the PERCs with standard etching treatment and further polishing processes on rear-side surfaces. Experimental results show that compared with the unpolished cell, the polished cell attained superior electrical performance, particularly in open-circuit voltage (Voc) and short-circuit current density (Jsc), because of the more effective rear-side surface passivation and reabsorption of long-wavelength light. The improvement in Voc and Jsc raised the conversion efficiency to 19.27%. This study verifies that despite polished cells requiring complex processes, the polishing treatment displays application potential for achieving high efficiency in the solar industry.

In this work, an efficient and green lipase-mediated technique has been mined for the amidation of anilines with 1,3-diketones via C–C bond cleavage. Under the optimal conditions, high yields (64.3%–96.2%) could be obtained when Novozym 435 was used as the catalyst. Furthermore, Novozym 435 exhibited a satisfying reusability and more than 80% of yield can be obtained after seven cycles. This work provides a more rapid and mild strategy for amide synthesis with high yield and expands the application of enzyme in organic synthesis.
