Although Indonesia is the largest grower of oil palm, other countries are also significant producers. Malaysia, Papua New Guinea, Costa Rica and Thailand are the next biggest oil palm seed producers. Due to this competition, some Indonesian plantation companies import oil palm germinated seeds from foreign producers. In addition, in order to widen the oil palm germplasm, especially for breeding purposes, countries engage in exchange or collection consortia and this can involve not only different countries, but also different continents, e.g. Africa, South America and Southeast Asia. One consequence of such import programmes is that each recipient of foreign germplasm must adhere to quarantine regulations, which are set up to protect the local species and commercial plantations by preventing the introduction of foreign pests and diseases. The regulations are usually issued and monitored by national governmental bodies, such as the Ministry of Agriculture, with inspections conducted by official quarantine agencies. Rules, regulations and processes vary from country to country. Here we give those that apply to Indonesia.

Published: August 2019

Apple snails are large freshwater snails belonging to the family Ampullariidae that inhabit tropical to temperate areas. The South American apple snails
Pomacea canaliculata
and
Pomacea maculata
have been introduced to other continents where they have successfully established and spread. Our review aims to analyse the mechanisms of the impacts that these invasive
Pomacea
provoke or may provoke. Nine basic mechanisms were identified: grazing/herbivory/browsing, competition, predation, disease transmission, hybridisation with native species, poisoning/toxicity, interaction with other invasive species, promotion of collateral damage of control methods on non-target; species and when acting as prey. The most important impacts are those related to their grazing on aquatic macrophytes, algae and rice and their competition and predation on other aquatic animals, mostly macroinvertebrates, including other apple snails. Invasive
Pomacea
are also responsible for outbreaks of an emergent parasitic disease (human eosinophilic meningitis). Their great abundance in invaded areas, their bioaccumulation of pollutants and their natural toxicity may impact on their predators and on trophic webs through apparent competition, trophic cascades and biomagnification. The biota from man-managed and natural wetlands may be unintentionally affected by mechanical, chemical and biological control against invasive
Pomacea
. Their capacity to hybridize may affect the distinctiveness and ecological traits of native
Pomacea
in invaded regions of America. Established populations of these invaders may either facilitate or resist the establishment of other exotic species. Field surveys and more realistic experimental approaches with multiple interacting species are needed to better understand the environmental impacts of invasive
Pomacea
and their underlying mechanisms.
A new method of integrating project‐based and work‐integrated learning in postgraduate engineering study
Authors: Karim Azharul , Campbell Matthew , Hasan Mahbub
Published: September 2019

This paper reflects on the introduction of project‐based learning (PBL) into a postgraduate engineering management unit, as a form of work‐integrated learning (WIL) extending the practice of students and their engagement with industry. The real life and authentic PBL was designed and implemented in extensive consultation with industry practitioners. WIL has often been conceptualized as a process of induction and introduction to workplaces and work practices. However, such models do not easily translate to postgraduate students with existing workplace experiences. The experience of this unit suggests that there is an intersection between PBL and WIL which may provide a pathway for broader student–industry engagement, scaffolding the development of professional networks and practices for students already within an engineering workplace, and allowing students to transform their practice and improve workplace capabilities. This paper presents a case study of the experience of students who have participated in an industryled and assessed project based learning experience as part of a unit in the Masters of Engineering Management course. Student satisfaction and engagement with the unit was extremely high, with students self‐reporting increased levels of confidence and ability to apply theoretical knowledge. It is concluded that through the integration of project‐based and WIL it is possible to create authentic learning experiences for postgraduate students which enable transformative practice and capability development.
Multiband effects in equations of motion of observables beyond the semiclassical approach
Authors: Stedman Troy , Timm Carsten , Woods Lilia M
Published: August 2019

The equations of motion (EOM) for the position and gauge invariant crystal momentum are considered for multiband wave packets of Bloch electrons. For a localized packet in a subset of bands well-separated from the rest of the band structure of the crystal, one can construct an effective electromagnetic Hamiltonian with respect to the center of the packet. We show that the EOM can be obtained via a projected operator procedure, which is derived from the adiabatic approximation within perturbation theory. These relations explicitly contain information from each band captured in the expansion coefficients and energy band structure of the Bloch states as well as non-Abelian features originating from interband Berry phase properties. This general and transparent Hamiltonian-based approach is applied to a wave packet spread over a single band, a set of degenerate bands, and two linear crossing bands. The generalized EOM hold promise for novel effects in transport currents and Hall effect phenomena.
Chimerapedia: coherence–incoherence patterns in one, two and three dimensions
Authors: Omel’chenko Oleh E , Knobloch Edgar
Published: August 2019

Chimera states, or coherence–incoherence patterns in systems of symmetrically coupled identical oscillators, have been the subject of intensive study for the last two decades. In particular it is now known that the continuum limit of phase-coupled oscillators allows an elegant mathematical description of these states based on a nonlinear integro-differential equation known as the Ott–Antonsen equation. However, a systematic study of this equation usually requires a substantial computational effort. In this paper, we consider a special class of nonlocally coupled phase oscillator models where the above analytical approach simplifies significantly, leading to a semi-analytical description of both chimera states and of their linear stability properties. We apply this approach to phase oscillators on a one-dimensional lattice, on a two-dimensional square lattice and on a three-dimensional cubic lattice, all three with periodic boundary conditions. For each of these systems we identify multiple symmetric coherence–incoherence patterns and compute their linear stability properties. In addition, we describe how chimera states in higher-dimensional models are inherited from lower-dimensional models and explain how they can be grouped according to their symmetry properties and global order parameter.

A radiofrequency oscillation is successfully superimposed on a plasma potential of a filamented source plasma in an ion beam source while maintaining a constant plasma density, in order to investigate effects of oscillating source plasma potential on an extracted ion beam. The experiment is preliminarily performed with a positive argon ion beam source. A class-D amplifier operational over a wide range of a frequency from a few tens of kHz to several MHz is installed; leading the oscillation of the plasma potential in the plasma source for the frequency range being tested. The beam current profile downstream of the extraction grids shows an oscillation of the beam current at the peripheral region of the ion beam; implying that the oscillation of a beam halo is induced by the potential oscillation of the source plasma.
Band topology in classical waves: Wilson-loop approach to topological numbers and fragile topology
Authors: Wang Hai-Xiao , Guo Guang-Yu , Jiang Jian-Hua
Published: August 2019

The rapid development of topological photonics and acoustics calls for accurate understanding of band topology in classical waves, which is not yet achieved in many situations. Here, we present the Wilson-loop approach for exact numerical calculation of the topological invariants for several photonic/sonic crystals. We demonstrate that these topological photonic/sonic crystals are topological crystalline insulators with fragile topology, a feature which has been ignored in previous studies. We further discuss the bulk-edge correspondence in these systems with emphasis on symmetry broken on the edges.
Time-energy filtering of single electrons in ballistic waveguides
Authors: Locane Elina , Brouwer Piet W , Kashcheyevs Vyacheslavs
Published: August 2019

Characterizing distinct electron wave packets is a basic task for solid-state electron quantum optics with applications in quantum metrology and sensing. A important circuit element for this task is a non-stationary potential barrier that enables backscattering of chiral particles depending on their energy and time of arrival. Here we solve the quantum mechanical problem of single-particle scattering by a ballistic constriction in an fully depleted quantum Hall system under spatially uniform but time-dependent electrostatic potential modulation. The result describes electrons distributed in time-energy space according to a modified Wigner quasiprobability distribution and scattered with an energy-dependent transmission probability that characterizes constriction in the absence of modulation. Modification of the incoming Wigner distribution due to external time-dependent potential simplifies in case of linear time-dependence and admits semiclassical interpretation. Our results support a recently proposed and implemented method for measuring time and energy distribution of solitary electrons as a quantum tomography technique, and offer new paths for experimental exploration of on-demand sources of coherent electrons.

Security system is a store generally still use a conventional security system. Conventional security devices used include padlock and Close Circuit Television (CCTV). CCTV devices have a function to record any activity or event as long as the store is active or outside of its activity hours. However, CCTV has disadvantages because CCTV only records without giving a notification if there is human movement in the room after the store’s operating hours end. Therefore we need a security system that can provide up-to-date information in real time to detect human movements within the store when it is outside its operating hours. The system was built using Passive InfraRed Sensors (PIR) which are connected to the microcontroller as the central control system to detect human movements outside the store’s operating hours based on the results of design and testing, this system can be used properly and provides real time notifications to users. When the sensor detects human movement outside the store’s operating hours, the system will send an SMS notification to the shop owner’s mobile number.

Published: August 2019

The development of the number of online shopping consumers in Indonesia is increasing. In 2016, research from e-Marketer estimated that it would reach 8.6 million people who shop through the internet. This figure increased from 7.9 million people in the previous year. The increasing number of people who know the internet along with the birth of generation Z (Gen Z) in the digital era makes changes in shopping habits that previously conventionally turned into online. Online transaction is an automatic ticket number that is used to differentiate transactions for each buyer. For example in the purchase transaction of goods in the online shop, each purchase transaction is distinguished through an additional three digits behind the nominal to facilitate payment into the seller’s account. The problem faced by the owner of the online shop is when BRI internet banking login to see account mutations, user authentication by entering the Captcha code. This process is repeated because there is a duration limitation for access to the system. It is necessary to check the account mutation automatically on a computer system that is able to read and recognize the character of the Captcha image. In this study, we propose the Template Matching method in recognizing characters in the captcha image. The dataset contains 300 images taken from the BRI internet banking website. The first step is to convert the extension from .png to .jpg. After the image is converted to extension .jpg the next step is pre-processing to correct the image of the noise that exists. Pre-processing result images that have been fixed are quality, then the separation of objects and background using Otsu. Then the process of labelling and segmentation. The characters are then processed using the Template Matching method so that they can be identified as numbers. The results of the experiments that have been carried out, found that the method we propose is able to recognize characters in the image with an accuracy rate of 90%. Errors in character recognition are due to characters that intersect, so when the results are processed the results do not match the ground truth.

Published: August 2019

Chronic Obstructive Pulmonary Disease (COPD) is a chronic disease that attacks the respiratory system caused by inflammation and pollutants that are sucked in the respiratory tract which will cause bronchial stiffness resulting in dyspnea or gasping breath. West Java itself has a prevalence of 3% including Ciamis. Dyspnea will reduce the ability of lung physiology which is marked by a decrease of peak expiratory flow rate<150 L which will eventually cause the death. The purpose of this study is to reduce dyspnea in COPD patients seen from the increase ofPEFR. The sample of this study was 25 medium classifications of COPD patients who were given the technique of Purse Lips Breathing 2 times a day in 7 days. The method of this research is one group pre-post test design with a sample of 25 COPD patients. The results of the study were tested by paired T-test where the results showed a P value of 0.00 <0.05, which means that there was a clear and significant increase in PEFR after given the Pursed lips breathing technique. Discussion of increasing PEFR requires consistency of COPD patients so that complementary therapy or even collaboration can be used to reduce dyspnea symptoms. As the conclusion, the increase of PEFR as a sign of reducing dyspnea does not stand alone but requiring a comprehensive examination, it can be used as the first measure of emergency breathing.

Nowadays many traders are cheating in selling meat that is not feasible for consumption to get a greater profit by mixing good meat with meat that is not feasible for consumption. So cause anxiety for the community because it has dangerous content. One way to help people in selecting meat through image processing can recognize objects. The purpose of this research is to know the quality of beef which is good and feasible to be consumed using the co-occurrence matrix to classify the meat image with K-NN algorithm. This research can be utilized to be able to distinguish the types of meat based on colour and texture. The data used in this research are 60 image data consisting of 30 images of fresh meat and 30 images of rotten meat. The classification process uses test data in order to distinguish the types of fresh meat and rotten meat. The mean feature value of this method with the feature features of the highest feature extraction is the homogeneity value feature. The results showed that the performance of the system using the KNN method to identify the quality of meat based on colour and texture can detect the type of beef.

Gamma Glutamyl Transferase is one of the most sensitive microsomal enzymes to detect liver parenchymal diseases. Gamma Glutamyl Transferase is an examination performed to measure the levels of GGT enzymes in the blood. The purpose of this study was to determine the results of GGT levels on bus drivers PT. Gapuraning Rahayu Ciamis who consume energy supplements with a total of 30 respondents. This research is descriptive, the data used are primary data presented in tabular form, incorporating narration. Based on the research that has been done on 30 respondents with the result 8 (27%) respondents high Gamma Glutamyl Transferase examination and 22 (83%) respondents with normal results. It can be concluded that the consumption of excessive energy supplements can increase Gamma Glutamyl Transferase levels.
Evolution of the charge carrier plasmon in the one-dimensional metal TTF-TCNQ as a function of temperature and momentum

Published: August 2019

We have investigated the charge carrier plasmon in the quasi one-dimensional metal TTF-TCNQ using electron energy-loss spectroscopy. Our data reveal a negative plasmon dispersion with a slope that is independent of temperature, which is in agreement to predictions from model calculations and previous room temperature data. A plasmon energy shift upon temperature is observed, and we discuss possible contributions to this shift. The spectral width of the plasmon is rather temperature independent, but increases clearly above a momentum value of about 0.3 Å−1.

Purpose

Millions of Americans who undergo surgical procedures receive opioid prescriptions as they return home. While some derive great benefit from these medicines, others experience adverse events, convert to chronic opioid use, or have unused medicines that serve as a reservoir for potential nonmedical use. Our aim was to investigate concepts and methods relevant to optimal opioid prescribing and pain treatment in the perioperative period.

Methods

We reviewed existing literature for trials on factors that influence opioid prescribing and optimization of pain treatment for surgical procedures and generated a conceptual framework to guide future quality, safety, and research efforts.

Results

Opioid prescribing and pain treatment after discharge from surgery broadly consist of 3 key interacting perspectives, including those of the patient, the perioperative team, and, serving in an essential role for all patients, the pharmacist. Systems-based factors, ranging from the organizational environment’s ability to provide multimodal analgesia and participation in enhanced recovery after surgery programs to other healthcare system and macro-level trends, shape these interactions and influence opioid-related safety outcomes.

Conclusions

The severity and persistence of the opioid crisis underscore the urgent need for interventions to improve postoperative prescription opioid use in the United States. Such interventions are likely to be most effective, with the fewest unintended consequences, if based on sound evidence and built on multidisciplinary efforts that include pharmacists, nurses, surgeons, anesthesiologists, and the patient. Future studies have the potential to identify the optimal amount to prescribe, improve patient-focused safety and quality outcomes, and help curb the oversupply of opioids that contributes to the most pressing public health crisis of our time.
QEEG Evidence for Stress-Reducing Effects of BLAST Technology in Hispanic Individuals

Objective

The aim of this archival study was to utilize quantitative electroencephalography (qEEG) recordings to explore the effects of Bilateral Alternating Stimulation Tactile (BLAST) technology on Hispanic individuals following the recollection of a stressful event. It was hypothesized that significant changes in the participants’ qEEG recordings would occur following the BLAST condition and that would, in turn, represent decreases in anxiety.

Participants and Method

The clinical sample consisted of 6 Hispanic individuals: 3 identified as Nicaraguan, and 3 identified as Hispanic/Biracial. Ages of the participants ranged from 6 years to 51 years, and they had various diagnoses such as ADHD, Specific Learning Disability, and Anxiety. 19-channel 5-minute qEEG recordings were collected utilizing a NeuroField Q20 amplifier and was stored using NeuroGuide at three different time points: a baseline measure when thinking of the stressful event, during the delivery of BLAST, and after removing the devices. Paired t-test analyses were conducted before and after BLAST with NeuroGuide’s Neurostat software.

Results

EEG recordings comparing the stress condition to the BLAST condition exhibited reduced activity in right frontal Theta at 4-8 Hz in the frontal channel locations (FP2, F4, and C4). Significant reductions were also found in Beta 1 at 12-14 Hz in the frontal channel locations (F3, FP2, and F7), reductions in Gamma at 40-50 Hz at C4, reductions in Delta (1-4 Hz) and Theta (4-8 Hz) at C4. Additionally, increases in high Beta (25-30 Hz) and Beta 2 were found at C4.

Conclusions

The results indicate that BLAST technology may be an appropriate intervention for Hispanic individuals to reduce cortex activity associated with anxiety and stress. Generalizability is difficult due to the study’s small sample size. Thus, a larger sample size should be recruited and tested to determine the sustainability of the effects in a more inclusive population.
