Characters’ nomination according to external features in Ilf and Petrov’s “12 chairs”
Authors: Ratushnaya Ekaterina R. , Savelyeva Maria V. , Timofeeva Tatyana P.
Published: October 2019

The paper presents the analysis of nomination according to the external features of the characters in the novel “The Twelve Chairs” by I. Ilf and Eu. Petrov. The characters’ nomination is understood as the main part of the anthroponymic system of the novel. The system of nominations denoting a person according to different aspects is viewed as a complex of multiple levels including several subsystems or semantic unities. One of them is a unity of nominations denoting characters according to their external features. Due to their semantic meaning the units can be divided into two groups: units denoting a person according to permanent physical characteristics (such as age, sex, appearance) and units denoting a person according to situational physiological state or condition. The nominations in question serve to present a vivid description of personages and to express the esthetic impression based on the analysis of physical, physiological and anthropological qualities and states visually perceived by the author of nomination. The article will also touch upon the ways the nominations are translated into English by native speaking translators.

Published: October 2019

The issue of preparing non-linguistic faculty students for intercultural interaction in the context of the subject-language integrated environment is quite a topical one, and theory and practice of higher education have accumulated considerable experience in this process. However, we have to admit that in modern pedagogical science no research has been so far dedicated either to the development of effective and logical system of preparing non-linguistic faculty students for intercultural interaction, or to the identification of optimal conditions for the functioning of such system. The statements above convinced us in the need to develop the respective proprietary system and pedagogical conditions, which would meet the peculiarities of the given age of students, of the requirements of the Federal State Education Standards of higher education, and of the requirements to the personality of the modern world reflected in national and international documents.

Authors: Margarita Smirnova , Elena Vasilenko
Published: October 2019

The article examines the influence of the national culture of India on modern design. The reflection of ethnic features in different types of art is considered. At the present stage of design development it is important to preserve the age-old traditions of art and culture, synthesis with modern life, materials and technologies. In this regard, of particular interest is the national culture, formed under the influence of economic and geographical (crossing the most important migration and trade routes of Eurasia), climatic conditions, artistic traditions and ancient religious beliefs. Empirical, theoretical and analytical research methods are necessary for the study of ethnic style design. For better perception, the history of Indian culture, which is rich in ancient religious buildings and monuments of architecture, was studied. The heritage of folk culture is a contribution to the art of designing modern design. The study revealed that the ethnic (Indian) style in design, has undergone numerous changes in its development, United the traditions of different cultures. Born before our era, Indian art has transformed from laconic and elementary forms into exquisite and multifaceted with an abundance of a decorative pattern. The growing interest of modern society in ethnic design, national art of the East, and in particular India, gives new opportunities for designers to use the centuries-old heritage of these countries in their activities.

Stereotypic image of Siberia in Russian mass media
Authors: Kondratyeva Olga , Valko Olga
Published: October 2019

The article studies theoretical aspects of the image of the region and their realization as exemplified by the image of Siberia. The article treats the structure of the image and mechanisms of its formation from the point of view of the cognitive approach and with the help of frame structures. The cognitive analysis enables to differentiate three levels: frame, subframes, and slots, pertaining to the entity explored. The research allows demonstrating that the stereotypical ideas play an essential role in forming and sustaining the images of regions. Mass media appear to be the main source of the stereotypic image of the region due to highlighting different facts concerning the sterotypicized phenomenon, selecting various linguistic means for featuring it and influencing the emotional and evaluative perception of the image. The study was based on the data of the National Corpus of the Russian Language, which were analyzed with the help of content analysis and frame analysis. The image of the Siberian region actively exploits the frames “Nature and Geography of Siberia”, “History of Siberia”, “Economy of Siberia”. The research found out the dynamic and ambivalent character of the stereotypic image of Siberia.
Localization in translation theory and practice: historical and cultural view (the case of fiction adaptation)
Authors: Mityagina Vera , Volkova Irina
Published: October 2019

The paper deals with the concept of localization and historical prerequisites of its use within the field of translation studies. We show that the sphere of localization techniques use is not limited by computer-mediated products but spreads on purely linguistic procedures of text adaptation as well. Since today there is no consensus among researchers and translators about the status of localization in the modern translation studies, we make an attempt to clarify the role and relevance of this term for the theory and practice of translation using the examples of fiction adaptation. The research is based on the material of a number of original and translated poetry works, including plays by W. Shakespeare and poems by Robert Burns, Ivan Krylov and Walter Scott. It is shown that the techniques of linguocultural adaptation used by translators in the 18th – 19th centuries are in fact those peculiar of the modern localization process. This fact proves the terminological value of the concept under study as the one denoting a certain type of translation activity which implies communicative equivalence and vague ties between the two texts. The considered examples of free translation of fiction prove that the process of localization is conditioned by literary and translational traditions, in particular, by the conception of free translation, which focused on the popularization of foreign works and a given ideological impact.

Authors: Zhura Viktoria. V. , Rudova Yulia. V.
Published: October 2019

The sociocultural backdrop of international students coming to a foreign country from different cultural and social environments plays a key role in shaping their attitude towards learning. The article explores and compares the motivational drives of international students from the Arab countries and India, which underlie their attitude to academic activities and academic progress. We used the method of systematic literature review, a questionnaire survey, comparative, quantitative, and qualitative analyses to obtain data on the value systems, traditions, and worldview of international students, which will make it possible for educators to appreciate the cultural contexts these students are embedded in. Social and cultural awareness of different aspects of the students’ value systems will enable teachers in host countries to contribute effectively to international student integration into the educational process.
Identification of the mechanisms responsible for anomalies in the tropical lower thermosphere/ionosphere caused by the January 2009 sudden stratospheric warming

We apply the Entire Atmosphere GLobal (EAGLE) model to investigate the upper atmosphere response to the January 2009 sudden stratospheric warming (SSW) event. The model successfully reproduces neutral temperature and total electron content (TEC) observations. Using both model and observational data, we identify a cooling in the tropical lower thermosphere caused by the SSW. This cooling affects the zonal electric field close to the equator, leading to an enhanced vertical plasma drift. We demonstrate that along with a SSW-related wind disturbance, which is the main source to form a dynamo electric field in the ionosphere, perturbations of the ionospheric conductivity also make a significant contribution to the formation of the electric field response to SSW. The post-sunset TEC enhancement and pre-sunrise electron content reduction are revealed as a response to the 2009 SSW. We show that at post-sunset hours the SSW affects low-latitude TEC via a disturbance of the meridional electric field. We also show that the phase change of the semidiurnal migrating solar tide (SW2) in the neutral wind caused by the 2009 SSW at the altitude of the dynamo electric field generation has a crucial importance for the SW2 phase change in the zonal electric field. Such changes lead to the appearance of anomalous diurnal variability of the equatorial electromagnetic plasma drift and subsequent low-latitudinal TEC disturbances in agreement with available observations.

Plain Language Summary– Entire Atmosphere GLobal model (EAGLE) interactively calculates the troposphere, stratosphere, mesosphere, thermosphere, and plasmasphere–ionosphere system states and their response to various natural and anthropogenic forcing. In this paper, we study the upper atmosphere response to the major sudden stratospheric warming that occurred in January 2009. Our results agree well with the observed evolution of the neutral temperature in the upper atmosphere and with low-latitude ionospheric disturbances over America. For the first time, we identify an SSW-related cooling in the tropical lower thermosphere that, in turn, could provide additional information for understanding the mechanisms for the generation of electric field disturbances observed at low latitudes. We show that the SSW-related vertical electromagnetic drift due to electric field disturbances is a key mechanism for interpretation of an observed anomalous diurnal development of the equatorial ionization anomaly during the 2009 SSW event. We demonstrate that the link between thermospheric winds and the ionospheric dynamo electric field during the SSW is attained through the modulation of the semidiurnal migrating solar tide.

Magnetic field controlled hybrid semiconductor and resistive switching device for non-volatile memory applications
Authors: Xiong Chengyue , Lu Ziyao , Yin Siqi , Mou Hongming , Zhang Xiaozhong
Published: October 2019

A magnetic-field-controlled non-volatile memory device is fabricated by coupling Hall effect and resistive switching effect. The non-volatile property of the device is due to the fact that the Hall voltage of the semiconductor changes the resistance state of the resistive switching unit. By changing the device configuration, the storage can be controlled by magnetic fields in different directions. The parameters of the semiconductors and the resistive switching units are experimentally investigated and simulated to optimize the performance of the devices. The key to increasing the ON/OFF ratio and reducing power consumption is finding a suitable resistance match between the semiconductor and the resistive switching unit. By enhancing the mobility of the semiconductor, the performance of the device can also be significantly improved. This hybrid device provides new insights into the manufacture of magnetic field controlled non-volatile memory devices with potential of integrating computing and storage functions.
Equation of motion coupled-cluster for core excitation spectra: Two complementary approaches
Authors: Park Young Choon , Perera Ajith , Bartlett Rodney J.
Published: October 2019

This paper presents core excitation spectra from coupled-cluster (CC) theory obtained from both a time-independent and a new time-dependent formalism. The conventional time-independent CC formulation for excited states is the equation-of-motion (EOM-CC) method whose eigenvalues and eigenvectors describe the core excited states. An alternative computational procedure is offered by a time-dependent CC description. In that case, the dipole transition operator is expressed in the CC effective Hamiltonian form and propagated with respect to time. The absorption spectrum is obtained from the CC dipole autocorrelation function via a Fourier transformation. Comparisons are made among the time-dependent results obtained from second-order perturbation theory, to coupled cluster doubles and their linearized forms (CCD and LCCD), to CC singles and doubles (CCSD) and the linearized form (LCCSD). In the time-independent case, considerations of triples (EOM-CCSDT) and quadruples (EOM-CCSDTQ) are used to approach sub-electron volt accuracy. A particular target is the allyl radical, as an example of an open-shell molecule. As the results have to ultimately be the same, the two procedures offer a complementary approach toward analyzing experimental results.
Good and bad predictions: Assessing and improving the replication of chaotic attractors by means of reservoir computing
Authors: Haluszczynski Alexander , Räth Christoph
Published: October 2019

The prediction of complex nonlinear dynamical systems with the help of machine learning techniques has become increasingly popular. In particular, reservoir computing turned out to be a very promising approach especially for the reproduction of the long-term properties of a nonlinear system. Yet, a thorough statistical analysis of the forecast results is missing. Using the Lorenz and Rössler system, we statistically analyze the quality of prediction for different parametrizations—both the exact short-term prediction as well as the reproduction of the long-term properties (the “climate”) of the system as estimated by the correlation dimension and largest Lyapunov exponent. We find that both short- and long-term predictions vary significantly among the realizations. Thus, special care must be taken in selecting the good predictions as realizations, which deliver better short-term prediction also tend to better resemble the long-term climate of the system. Instead of only using purely random Erdös-Renyi networks, we also investigate the benefit of alternative network topologies such as small world or scale-free networks and show which effect they have on the prediction quality. Our results suggest that the overall performance with respect to the reproduction of the climate of both the Lorenz and Rössler system is worst for scale-free networks. For the Lorenz system, there seems to be a slight benefit of using small world networks, while for the Rössler system, small world and Erdös-Renyi networks performed equivalently well. In general, the observation is that reservoir computing works for all network topologies investigated here.

Nitroimidazoles are important compounds in medicine, biology, and the food industry. The growing need for their structural assignment, as well as the need for the development of the detection and screening methods, provides the motivation to understand their fundamental properties and reactivity. Here, we investigated the decomposition of protonated ronidazole [Roni+H]+ in low-energy and high-energy collision-induced dissociation (CID) experiments. Quantum chemical calculations showed that the main fragmentation channels involve intramolecular proton transfer from nitroimidazole to its side chain followed by a release of NH2CO2H, which can proceed via two pathways involving transfer of H+ from (1) the N3 position via a barrier of TS2 of 0.97 eV, followed by the rupture of the C–O bond with a thermodynamic threshold of 2.40 eV; and (2) the –CH3 group via a higher barrier of 2.77 eV, but with a slightly lower thermodynamic threshold of 2.24 eV. Electrospray ionization of ronidazole using deuterated solvents showed that in low-energy CID, only pathway (1) proceeds, and in high-energy CID, both channels proceed with contributions of 81% and 19%. While both of the pathways are associated with small kinetic energy release of 10–23 meV, further release of the NO• radical has a KER value of 339 meV.
Meta-interface enhanced light tunneling effect and related electromagnetic diode action
Authors: Yao Tian , Zhu Kejia , Chen Yongqiang , Lin Ruina , Shi Chunyan , Fang Yu , Wu Xingzhi , Sun Yong , Wu Quanying
Published: October 2019

A subwavelength electromagnetic diode scheme is proposed that includes a light tunneling heterostructure with an embedded Fano-like highly dispersive metainterface. Due to the presence of the Fano-like metainterface, the transmission properties of the light tunneling heterostructure, including its Q-factor and electromagnetic field, can be optimized for a better diode behavior. The concept is demonstrated based on a microstrip transmission line system with asymmetric absorption and nonlinear medium inclusion. This configuration is found to generate an extremely high transmission contrast of up to 18.5 dB at a working frequency of 725 MHz. A further advantage of the configuration is that, with an input power intensity of only 8.2 dBm, the unidirectional transmission can still exceed −30 dB. These features may be useful in the design of integrated ultralow-power nonlinear devices.

Published: October 2019

All-optical data processing continues to attract significant interest as a way to overcome the electronic signal processing bottleneck of fiber telecommunication networks. Nonlinear optical devices such as limiters and saturable absorbers rely on intensity-dependent attenuation of light. However, making such devices using intensity-dependent multiphoton dissipation processes is an issue as these make complete absorption and transmission impossible. Here, we show that nonlinear phase retardation in an optical fiber can control the dissipation of coherent light waves interacting on a thin plasmonic absorber from total absorption to perfect transmission. The fiber’s instantaneous Kerr nonlinearity and the femtosecond coherent absorption time scale make this approach ultrafast. We report proof-of-principle demonstrations of all-optical intensity discrimination, power limiting, pulse restoration, pulse splitting, and signal transfer between carrier wavelengths within a fiber circuit. Our results indicate that nonlinear control of coherent absorption can imitate and outperform saturable and multiphoton absorption in terms of bandwidth and contrast.

Blow-up and global solubility in the classical sense of the Cauchy problem for a formally hyperbolic equation with a non-coercive source
Authors: Korpusov M. O.
Published: October 2019

We consider an abstract Cauchy problem with non-linear operator coefficients and prove the existence of a unique non-extendable classical solution. Under certain sufficient close-to-necessary conditions, we obtain finite-time blow-up conditions and upper and lower bounds for the blow-up time. Moreover, under certain sufficient close-to-necessary conditions, we obtain a result on the existence of a global-in-time solution independently of the size of the initial functions.
Productive and receptive processes in PT
Authors: Spinner Patti , Jung Sehoon
Published: October 2019

In this study, we investigate whether Processability Theory (Pienemann, 1998, 2005)
accounts for reception data, and whether productive and receptive processing routines emerge
simultaneously. Sixty-one learners of English as a second language (ESL learners)
participate in an oral interview and self-paced reading (SPR) task targeting five stages of
PT. Two analyses are performed: Implicational scaling and a comparison of individuals’
performance on the oral interview versus the SPR. The implicational table demonstrates that
the SPR data do not clearly reflect the PT order, and the comparison data demonstrate that
individuals’ performance on the oral production task does not match their performance on the
SPR task. The results suggest that PT as currently formulated may not account for receptive
data, and that productive and receptive processes may not always emerge simultaneously.
Case within the phrasal procedure stage
Authors: Artoni Daniele
Published: October 2019

This chapter investigates the acquisition of case in Russian L2 within the VP
and the PP, two structures belonging to the same Processability Theory (PT)-based stage of
acquisition, namely the Phrasal procedure stage. I claim that a crucial aspect of the
intra-stage development is determined by the different nature of case assignments involved
in the given structures. The study is conducted with a group of 15 learners of Russian L2
with varied L1 backgrounds. The analysis of their semi-spontaneous speech shows that (1)
case within the VP develops from lack of case assignment to configurational, lexical, and
eventually grammatical assignment, and (2) case within the PP develops from lack of case
assignment to configurational and lexical case assignments. To conclude, the study confirms
the cross-linguistic prediction that case develops from no marking to case assignment by
position, and eventually to grammatical case assignment.

In this chapter we explore how the Multiplicity framework of the communicative
repertoire offers ways to expand understandings of Hypothesis Space and widens insights into
the process of second language acquisition currently offered by PT. We focus on the
potential of the Multiplicity framework for capturing and explaining variation in learners’
communicative acts that occur in response to varied pressures in moments of communication.
We suggest that these insights offer a different means of connecting the Hypothesis Space
with learners’ acquisition trajectories. seek to embrace both the concept of shared developmental stages that has
been the centrepiece of PT to date and relate features of development to variation within
moments of interaction.

Published: October 2019

Horizontal force‐velocity (F‐V) profiling is a strategy to assess athletes’ individual performance capabilities during sprinting. This study investigated the acute changes in F‐V profiles during sprinting of fourteen collegiate male sprinters with a mean 100‐m sprint time of 11.40 ± 0.39 s, from a split‐stance starting position. The subjects sprinted 30‐m with, and without, wearable resistance (WR) equivalent to 2% body mass, attached to their forearms. Sprinting time at 5, 10, 20, and 30‐m was assessed using laser technology. External horizontal F‐V relationships were calculated via velocity‐time signals. Maximal theoretical velocity (V 0), theoretical relative and absolute horizontal force (F 0), and horizontal power (P max) were determined from the F‐V relationship. Paired t‐tests were used to determine statistical differences (p ≤ 0.05) in variables across conditions with Cohen's d as effect sizes (ES) calculated to assess practical changes. Sprint times at 10‐m and beyond were significantly increased (1.9–3.3%, p 0.01–0.03, ES 0.46–0.60) with WR compared to unloaded sprinting. The only significant change in F‐V with the WR condition was found in relative P max system (−6.1%, p 0.01, ES 0.66). A small decrease was reported in V 0 (−1.0%, p 0.11, ES 0.27), with small to medium ES decreases reported in F 0 (−4.8% to −6.1%, p 0.07–0.21, ES 0.25‐0.51) and P max (−4.3% to −4.6%, p 0.06–0.08, ES 0.32–0.45). The greater changes to F 0 and P max suggest that forearm WR may be a possible training tool for athletes who wish to focus on force and power adaptation during sprint acceleration from a standing start.

Improving entanglement of assistance by local parity–time symmetric operation*
Authors: He Zhi , Nie Zun-Yan , Wang Qiong
Published: October 2019

We investigate entanglement of assistance without and with decoherence using a local non-Hermitian operation, i.e., parity–time (

P
T

) symmetric operation. First we give the explicit expressions of entanglement of assistance for a general W-like state of a three-qubit system under a local parity–time symmetric operation. Then for a famous W state without decoherence, we find that entanglement of assistance shared by two parties can be obviously enhanced with the assistance of the third party by a local parity–time symmetric operation. For the decoherence case, we provide two schemes to show the effects of local parity–time symmetric operation on improvement of entanglement of assistance against amplitude damping noise. We find that for the larger amplitude damping case the scheme of

P
T

symmetric operation performed on one of two parties with the influence of noise is superior to that of

P
T

symmetric operation performed on the third party without the influence of noise in suppressing amplitude damping noise. However, for the smaller amplitude damping case the opposite result is given. The obtained results imply that the local

P
T

symmetric operation method may have potential applications in quantum decoherence control.
Tensor force effect on the exotic structure of neutron-rich Ca isotopes *
Authors: Wang Yan-Zhao , Su Xue-Dou , Qi Chong , Gu Jian-Zhong
Published: October 2019

The structure of neutron-rich Ca isotopes is studied in the spherical Skyrme-Hartree-Fock-Bogoliubov (SHFB) approach with SLy5, SLy5+T, and 36 sets of TIJ parametrizations. The calculated results are compared with the available experimental data for the average binding energies, two-neutron separation energies and charge radii. It is found that the SLy5+T, T31, and T32 parametrizations reproduce best the experimental properties, especially the neutron shell effects at N = 20, 28 and 32, and the recently measured two-neutron separation energy of 56Ca. The calculations with the SLy5+T and T31 parametrizations are extended to isotopes near the neutron drip line. The neutron giant halo structure in the very neutron-rich Ca isotopes is not seen with these two interactions. However, depleted neutron central densities are found in these nuclei. By analyzing the neutron mean-potential, the reason for the bubble-like structure formation is given.

Published: October 2019

This research aimed to investigate the potential use of banana peels waste for sheep feeding. Completely randomized design was used to compare the chemical, phenol, and tannin compositions between raw and ripened banana peels from 4 different varieties (Ambon, Muli, Nangka, Kapas). Moreover, a 2x4 factorial design was used to test the main effects of ripening stages (raw, ripened) and doses (10, 20, 30, 40%) of Ambon banana peels on in vitro dry matter and organic matter digestibility (DMD and OMD, %), ammonia (NH3, mM), volatile fatty acids (VFA, mM), pH, and total gas production (TGP, ml). Raw banana peels contained less (P<0.05) dry matter (DM, %) and total digestible nutrients (TDN, %) but it contained higher (P<0.05) crude fiber (CF, %) and gross energy (GE, kcal/kg) compared with ripened banana peels. Raw and ripened banana peels contained considerable amount of total phenols (TP, %) and total tannins (TT, %) although being not different (P>0.05). Based on in vitro assessments, raw Ambon banana peels had lower (P<0.001) DMD, OMD, and VFA but higher NH3 (P<0,001) than ripened ones. Adding Ambon banana peels from 10 to 40% replacing roughage in the diet increased (P<0.001) DMD, OMD, and VFA but decreased (P<0,001) NH3. Both raw and ripened Banana peels have the potential for sheep feeding based on their chemical and in vitro assessments.

Torch Ginger (Etlingera elatior (Jack) R. M. Smith) is plant material that can be used as a medicine, food, cosmetics, and bio-pesticides. The existence of torch ginger in nature is becoming more limited due to the utilization of health care services mainly as a medicine continues to increase. In conventionally, plant propagation of torch ginger is derived from a rhizome, but seedlings produced tend to have the level of low proliferation and susceptible to infections of soil pathogens. This research aimed to know the influence of sucrose and BAP concentration on bud growth of torch ginger in in vitro. The research was conducted in the Tissue Culture Laboratory Universitas Islam Negeri Sunan Gunung Djati Bandung. Research method used was a descriptive design with experiment treatments i.e. sucrose (20 g/L, 40 g/L, and 60 g/L) and BAP (0 mg/L and 1 mg/L). The result showed that the use of sucrose 40 g/L + BAP 1 mg/L gave the best response to the shoot growth on 6 WAI and capable to produce green shoots on 8 WAI.

Capsaicin is a compound that produces a spicy taste in chili. Inheritance of capsaicin is valuable information for breeders to determine the selection methods and when the selection will be conducted. The objective of this experiment is to observe the inheritance pattern of the capsaicin content of Indonesian chili landraces. The experiment was conducted at Ciparanje Experimental Station of Universitas Padjadjaran. One hundred sixty-seven F2 plants were analyzed for capsaicin content in the laboratory. The results showed the distribution of capsaicin content was continuous using the Kolmogorov Smirnov test. Many genes might control capsaicin content in Indonesia chili landrace. The capsaicin content of the male parent was 4,565 ppm, and the female parent was 8,540 ppm. The capsaicin content among F2 plants ranged from 621 ppm to 14,348 ppm. The average of capsaicin content in the F2 population was 4,814 ppm. The capsaicin content of some F2 progenies showed higher than their male parents. However, some F2 progenies showed also low capsaicin content compared with their female parent. Segregation transgressive of capsaicin content occurred in F2 generation.

Development of food crops is not only addressed to a momentary increase in production but also attention to the aspect of land conservation in order for the system of production can be sustainable. Intercropping system is one way of managing agricultural land which can minimize the risk in the utilization of dry land for the development of food crops. The availability of water on dry land are generally affected by rainfall and the ability of the soil to retain water. The potential water resources available in the ground is indispensable in agricultural hydrology and water management in the framework of developing food crops. This study aims to determine the moisture content of the soil and water balance of the land in the region of Arjasari, Bandung Regency. The methods used in this research is a descriptive analysis. The research was carried out from March until November 2015. The results of this study showed that the moisture content of the soil in the study ranged from 314.2 mm/m up to 472 mm/m with the moisture content of the soil which can be utilized by the plant a maximum of 185 mm/m.

Land optimizing in oil palm plantation could be conducted by adopting polyculture cropping system of maize grown under oil palm trees during immature stage (IS) due to wider plant distance. The maize growth depends on genetic and environmental condition such as soil fertility, in fact oil palm plantation is often located in marginal area which is lack of fertility like Inceptisol soil type in Jatinangor, so that it needs supply of biofertilizer to improve soil fertility. This study was to get interaction effect between biofertilizer application and kind of maize varieties that is giving best effect on growth and yield of maize under polyculture system of immature oil palm trees. The experiment was conducted from November 2017 to February 2018. The experimental design was using split plot which was biofertilizer as a main plot and biofertilizer application as a subplot. The result showed all varieties of maize gave significant effect on plant height, leaves number, and cob size. Independently, maize variety of DR6 gave the best effect on plant height at 4 and 6 WAP (weeks after planting), DR1 gave the best effect on leaves number at 4, 6, 8 WAP, and DR5 gave the best effect on cob size.

Pesticide action can leave a residue in plant, including in the nectar and pollen of the flowers. Besides residues, sprays of pesticides could also make unintended possible effect to honey bee and other pollinators. Pollinators have a great impact on plant productivity, so it was important to keep the pollinators in healthy and in high diversity for sustainable of environment, food, and economy. The research was aimed to obtain valuable information regarding on pesticide use in both locations. The survey was divided into two steps. First, we did a preliminary survey to determine representative locations of study, and then followed by the second step, it was in-depth interview of pesticide use directly with 61- and 51 respondents in Pangalengan and Majalengka, respectively. Ninety six pesticide trademarks were applied by farmers in Pangalengan, meanwhile, 83 trademarks were in Majalengka with the variable bioactive compound. Neonicotinoids as bioactive of some pesticides were found only in one farmer from Pangalengan who used Alika (pesticide brand name). Besides, there were 13 active ingredients of fungicides, 15 insecticides, one herbicide, and one molluscicide found in Pangalengan. In Majalengka, there were 9 active ingredients of fungicides, 19 insecticides, and one molluscide. They usually applied herbicides, insecticides, and fungicides at least twice a week during crop cultivation. Although some farmers may be aware of pesticide hazards, adequate protection is hardly taken to minimize the risks. Sixty percent of farmers mentioned the presence of honeybees on their land. Farmers’ knowledge in the use of pesticides is appropriate and safe for both the health of pollinators and farmers when applying pesticides in the field.
