Abstract. Triwidodo H, Listihani. 2020. High impact of PGPR on biostatistic of Aphis craccivora (Hemiptera: Aphididae) on yardlong bean. Biodiversitas 21: 4016-4021. Plant growth-promoting rhizobacteria (PGPR) are root colonizing bacteria that live and develop near plant roots, which boost plant growth and act as antagonist agents. This research is aimed to asses the effect of PGPR on biostatistics of Aphis craccivora Koch on yardlong bean (Vigna unguiculata subsp. sesquipedalis). The research was conducted at WiSH Laboratory in Bogor, Indonesia, by tested PGPR mixture of Rhizobium, Bacillus polymyxa, and Pseudomonas fluorescens. The research discovered that the application with seed treatment and watered of PGPR affects the biology of Aphis craccivora in terms of lengthening its stadia of second instar nymph, lengthening its life cycle, and declining its fecundity. The application of PGPR also affects the biostatistics of Aphis craccivora. PGPR applied plants have a gross reproduction rate (GRR), net reproduction rate (Ro) and intrinsic increase rate (r) of Aphis craccivora that are lower than control. PGPR could slower the doubled time (DT) of Aphis craccivora to become lengthier than control. PGPR could improve plant growth: it could increase the number and length of roots, number of root nodules, plant height, number of leaves, as well as length and density of trichome.

Abstract. Elfidasari D, Wijayanti F, Muthmainah HF. 2020. Short Communication: The effect of water quality on the population density of Pterygoplichthys pardalis in the Ciliwung River, Jakarta, Indonesia. Biodiversitas 21: 4100-4106. The quality of waters is determined by the average value of the measured parameter range with a direct impact on aquatic biota due to pollution. The Ciliwung River is one of the polluted waters in Jakarta, which is the habitat for Pterygoplichthys pardalis (plecos catfish) that dominates the river. This study, therefore, aimed to analyze the influence of Ciliwung River quality on the density of P. pardalis. Data were obtained by measuring DO, BOD, pH, rainfall, temperature, water clarity, turbidity, current velocity, river depth, ammonia, and phosphate levels, as well as the fish population density. The research result showed that the density of P. pardalis population was greatly influenced by the DO, BOD, pH, turbidity, and ammonia parameters of the Ciliwung River. The waters quality with the DO condition of 2.6 mg/L, BOD of 1,2 mg/L, pH of 7.2, the turbidity of 3.85 FTU and ammonia of 2.65 ppm were the optimum conditions for the highest population density of P. pardalis in the Ciliwung River

Zusammenfassung
Die Digitalisierung der Stationsautomatisierung eröffnet neue Anwendungspotentiale für intelligente Stationsfunktionen in elektrischen Energiesystemen. Die Vernetzung und der Einsatz von IEC 61850 als vereinheitlichter Kommunikationsstandard ist eine wichtige Voraussetzung, erhöhen aber gleichzeitig die Anfälligkeit für IT-Angriffe. Zur Untersuchung der IT-Sicherheit digitaler Stationen wird hierfür eine neu konzipierte cyber-physische Echtzeit-Co-Simulationsplattform vorgestellt. Auf Basis einer Referenzarchitektur eines IP-basierten Umspannwerks wird die Modellierung, Bewertung und Analyse digitaler Stationen für gestörte und ungestörte Betriebsfälle sowie unter Beachtung von IT-Angriffen ermöglicht. Daraufhin werden Ansätze zur Resilienzbewertung sowie Maßnahmen zur IT-Sicherheit für den operativen Betrieb, z. B. die Erkennung cyber-physischer Anomalien, aufgezeigt.

Published: September 2020

Zusammenfassung
Der Zubau von Hochspannungsgleichstromtrassen zieht die Notwendigkeit der Detektion der Einflüsse dieser Trassen auf den Leistungsfluss im Stromnetz nach sich. Bereits existierende Methoden zur Aufschlüsselung partieller Leistungsflüsse basieren auf Vereinfachungen und Annahmen, die verhindern, dass nach Addition aller Teilflüsse das AC-Leistungsflussergebnis erreicht wird. Somit sind die Methoden ungenau und verfälschen die Ergebnisse. Die hier vorgestellte Methode der Power Flow Decomposition (PFD) basiert auf dem AC-Leistungsfluss und ermittelt ohne eine Slackdefinition sämtliche Teilflüsse eines Betriebsmittels. Es ist dargestellt, wie die PFD-Methode um HGÜ-Flüsse erweitert wird, um damit auch den Einfluss der HGÜ-Systeme ermitteln zu können. Die Verifikation der Methode wird an einem Beispielnetz vorgenommen.

Abstract
In Germany, the installed capacity of renewables exceeds the maximum load by far and the transmission task has changed from high-wind locations in the north to the economically strong south. In addition, the system inertia is reduced due to the decommissioning of large power stations. This leads to a higher probability of blackouts and a challenging restoration process. Operation during restoration differs strongly from normal. Besides other effects, the grid frequency is very sensitive to active power imbalances. An accurate power forecast of re-supplied feeders is required to estimate dynamic frequency deviations. Models for cold load pick-up (CLPU) and fluctuating renewable energy sources (RES) infeed are presented. For the coordination between Transmission system operators (TSO) and Distribution system operators (DSO) a clear and structured process is proposed to minimize the communication effort. Power system restoration (PSR) simulations are carried out and the results are presented.

Published: September 2020

AbstractA dysprosium(iii) organic framework, {[Dy(H2O)(BTCTB)]·2H2O}n (1, H3BTCTB = 3,3′,3′′-[1,3,5-benzenetriyltris(carbonylimino)]tris-benzoic acid), was synthesized through the hydrothermal reaction of Dy(NO3)3 with the C3-symmetric organic ligand H3BTCTB at 160°C for 96 h. At the same time, the sensitivity of picric acid in water medium was tested with material 1 as the fluorescent sensor. The detection limit was 0.71 µM and KSV of this experiment was 8.55 × 104 M−1, which might be attributed to the presence of abundant amide groups in the framework of 1. In addition, the treatment effect of compound 1 against the NCI-H292 lung cancer cells was evaluated. The Cell Counting Kit-8 (CCK-8) method was conducted to measure the viability of cancer cell after treated through the compound 1. The DCFH-DA was applied for the determination of ROS. The relative expression of the inflammatory genes was measured with RT-PCR. The western blotting was conducted to detect the effect of the compound against MDM-2 levels in NCI-H292 lung cancer cells. The possible binding interactions in terms of binding poses are probed by performing molecular docking simulations.

AbstractSelenium (Se) as a bioactive micronutrient could be augmented via transforming into nanoparticles (NPs), especially using biogenic protocols, for usage as an antimicrobial element. The reducing power of costus (Saussurea costus) root extract (SCE) was employed for phytosynthesis of Se-NPs through a simple and rapid protocol that included stirred mixing of 10 mM Na2SeO3with 1.0% SCE solution for 4 h. The phytosynthesized SCE/Se-NP composite was obtained with a mean diameter of 6.13 nm and a zeta potential of −42.8 mV. Infrared analyses revealed the involvement of many SCE phytogroups in Se-NP synthesis, whereas transmission microscopy displayed well distribution and spherical shapes of the phytosynthesized NPs. The antibacterial assessments against foodborne pathogens (Escherichia coli,Salmonella typhimuriumandStaphylococcus aureus) revealed the superior powers of SCE/Se-NPs and the elevated potentialities of SCE and Se-NPs for inhibition of bacterial pathogens. The scanning micrographs indicated that SCE/Se-NPs were attached to bacterial cells and led to their complete lysis/explosion with exposure prolongation. The SCE/Se-NP composites are recommended for the effective control of foodborne bacterial pathogens, applying a simple and eco-friendly phytosynthesis protocol.
An RNA-centric view on gut Bacteroidetes
Authors: Ryan Daniel , Prezza Gianluca , Westermann Alexander J. 
Published: September 2020

Abstract
Bacteria employ noncoding RNAs to maintain cellular physiology, adapt global gene expression to fluctuating environments, sense nutrients, coordinate their interaction with companion microbes and host cells, and protect themselves against bacteriophages. While bacterial RNA research has made fundamental contributions to biomedicine and biotechnology, the bulk of our knowledge of RNA biology stems from the study of a handful of aerobic model species. In comparison, RNA research is lagging in many medically relevant obligate anaerobic species, in particular the numerous commensal bacteria comprising our gut microbiota. This review presents a guide to RNA-based regulatory mechanisms in the phylum Bacteroidetes, focusing on the most abundant bacterial genus in the human gut, Bacteroides spp. This includes recent case reports on riboswitches, an mRNA leader, cis- and trans-encoded small RNAs (sRNAs) in Bacteroides spp., and a survey of CRISPR-Cas systems across Bacteroidetes. Recent work from our laboratory now suggests the existence of hundreds of noncoding RNA candidates in Bacteroides thetaiotaomicron, the emerging model organism for functional microbiota research. Based on these collective observations, we predict mechanistic and functional commonalities and differences between Bacteroides sRNAs and those of other model bacteria, and outline open questions and tools needed to boost Bacteroidetes RNA research.

Published: September 2020

Abstract

Objectives
Young adults with cerebral palsy (CP) face potential challenges. The transition to young adulthood is characterized by significant changes in roles and responsibilities. Furthermore, young adults with chronic conditions face a transfer from pediatric care to adult healthcare. This study explores how living with CP affects young adults in general, and specifically which psychosocial, medical and healthcare needs are particularly important during this phase of life.

Methods
A qualitative study with data from individual, semi-structured, in-depth interviews with six young adults with CP (ages 21–31 years) were transcribed verbatim and analyzed. The participants were selected to provide a maximum variation in age, gender, Gross Motor Function Classification System score and educational background. A descriptive thematic analysis was used to explore patterns and identify themes.

Results
Three themes were identified: “Being a Young Adult”, “Development in Physical Disability and New Challenges in Adulthood” and “Navigating the Healthcare System”. The three themes emerged from 15 sub-themes. Our findings emphasized that young adults with CP faced psychosocial challenges in social relationships, participation in education and work settings and striving towards independence. The transition to young adulthood led to a series of new challenges that the young adults were not prepared for. Medical challenges included managing CP-related physical and cognitive symptoms and navigating adult health care services, where new physicians with insufficient knowledge regarding CP were encountered.

Conclusion
The young adults with CP were not prepared for the challenges and changes they faced during their transition into adulthood. They felt that they had been abandoned by the healthcare system and lacked a medical home. Better transitional care is urgently needed to prepare them for the challenges in young adulthood.
Investigation of the flow patterns and power requirements in agitated systems: effects of the design of baffles and vessel base
Authors: Foukrach Mohammed , Ameur Houari 
Published: September 2020

Abstract
The flow patterns and power consumption of a six-blade Rushton turbine (RT) in a cylindrical vessel are characterized in this paper. We focus on the effects of the shape of the vessel base by studying two cases: a conical and a dished shape. In addition, the effects of the height of the vessel base (h
2) are explored and four cases are considered, namely: h
2/D = 1/10, 1/6, 1/5 and 1/3 (D: vessel diameter). In the second part of our investigation, a new design of baffles (a triangular-shaped baffle) is suggested and a comparison is made between the performance of the standard and the triangular baffles. The main findings revealed that the conical shape of the vessel base provides a slight enhancement in the axial circulation at almost the same power input for the dished bottomed vessel. For Re < 2 × 104, the power required by both types of baffles is the same; however, above this value of Re, a reduction by about 4% in power consumption is given by the standard baffles. Also, and for all shapes of baffles and vessel bases, a reduction in power consumption may be obtained by increasing the height of the vessel base.

Published: September 2020

Abstract
Esterification of glycerol with acetic acid was carried out over cerium-modified ZSM-5 zeolites to synthesize monoacetin (MA) and diacetin (DA). The modified zeolite catalyst was characterized. The effect of reaction process parameters such as acetic acid to glycerol mole ratio (1–11), reaction temperature (30–120 °C), and catalyst weight (2–8 wt %) on the selectivity of the product was investigated. At 120 °C reaction temperature, 8 wt % catalyst, and 9:1 acetic acid to glycerol mole ratio, about 98.32% conversion of glycerol were obtained. This reaction follows pseudo-first-order reaction kinetics and the activation energy was found to be 63.72 kJ mol−1.
A model for calculating losses in transformer related to orders and harmonic amplitude under analysis of joule effect, eddy current and hysteresis

Published: September 2020

AbstractThe electrical transformer is one of the most used equipment in electrical power systems. The non-linear electrical loads are increasing, mainly in the electrical distribution system, and the electrical power transformer is inserted in this scenario, supplying these loads. Consequently, the increasing non-linear loads affect the electrical transformers and their factors directly, like in the dependency between temperature and harmonic increase. Therefore, to study the influence of harmonics in the transformer’s temperature, one should understand how it will behave with these changes in the electrical power system. For this reason, in this article, numeric simulations and tests were performed to predict the transformer temperature behavior. The proposal is a numeric technique for coupling two equations, thermal and electromagnetic, of an electrical transformer, considering heat sources regarding joule, eddy current, and hysteresis effect. To evaluate the numeric simulation and understanding the electrical transformer behavior in real-life, tests with specific harmonic orders (3rd, 5th, and 7th) and their combinations and a test with less than 10% total harmonic distortion, according to IEEE 519 standard were performed. It is verified that the electrical transformer temperature rises with the increase in harmonic amplitude and its orders. Results show that the industry must be aware of the effects of the increasing non-linear loads when designing the next generation of transformers concerning their durability and lifetime.

Link failure recovery using p-cycles in wavelength division multiplex (WDM) mesh networks
Authors: Mohan Neeraj , Gupta Surbhi , Bhandari Abhay 
Published: September 2020

Abstract
Network survivability has become a crucial requirement in all types of computer networks. It becomes even more significant for wavelength division multiplex (WDM) mesh networks due to their high speed and capacity. These networks are prone to link failures. A link failure may be a single or multiple link failure. A single-link failure is easy to locate and fix as compared to multiple link failures. A dual-link failure recovery technique has been proposed using p-cycles. This technique uses a replication method for the p-cycle circle. It is an enhancement of the original failure independent path protection p-cycle scheme. The replica properties of p-cycle have been used to protect the nodes through the same p-cycle available. Creating a new p-cycle always adds to the cost of the network, whereas using a replica of already existing p-cycle significantly reduces the network cost. The proposed technique is implemented using network simulator in three phases.

Abstract

Objectives
Hypoparathyroidism is a rare disease in children that occurs as a result of autoimmune destruction of the parathyroid glands, a defect in parathyroid gland development or secondary to physical parathyroid gland disturbance. Typical symptoms of hypoparathyroidism present as hypocalcaemia and hyperphosphatemia due to decreased parathyroid hormone secretion and may lead to nerve and muscles disturbances resulting in clinical manifestation of tetany, arrhythmias and epilepsy. Currently, there is no conventional hormone replacement treatment for hypoparathyroidism and therapeutic approaches include normalising mineral levels using an oral calcium supplement and active forms of vitamin D.

Case presentation
We present the case of a 10-year-old girl with primary hypoparathyroidism who had no prior history of autoimmune disorders, but who subsequently developed systemic lupus erythematosus.
Readiness for transition to adult care in adolescents and young adults with Turner syndrome
Authors: Sheanon Nicole M. , Beal Sarah J. , Kichler Jessica C. , Casnellie Lori , Backeljauw Philippe , Corathers Sarah 
Published: September 2020

Abstract

Objectives
Turner syndrome (TS) is a complex and chronic medical condition that requires lifelong subspecialty care. Effective transition preparation is needed for successful transfer from pediatric to adult care in order to avoid lapses in medical care, explore health issues such as fertility, and prepare caregivers as adolescents take over responsibility for their own care. The objective of this study was to evaluate accuracy of knowledge of personal medical history and screening guidelines in adolescents and young adults (AYA) with TS.

Methods
This was a prospective cross-sectional study of 35 AYA with TS of ages 13–22 years recruited from a tertiary care center. AYA completed questionnaires on personal medical history, knowledge of screening guidelines for TS, and the Transition Readiness Assessment Questionnaire (TRAQ).

Results
Eighty percent of AYA with TS were 100% accurate in reporting their personal medical history. Only one-third of AYA with TS were accurate about knowing screening guidelines for individuals with TS. Accuracy about knowing screening guidelines was significantly associated with TRAQ sum scores (r = 0.45, p < 0.05). However, there was no association between knowledge of personal medical history and TRAQ sum scores.

Conclusions
Transition readiness skills, TS-specific knowledge, and accurate awareness of health-care recommendations are related, yet distinct, constructs. Understanding of one’s personal medical history is not an adequate surrogate for transition readiness. Validated tools for general transition, like the TRAQ, can be used but need to be complemented by TS-specific assessments and content. Providers are encouraged to identify opportunities for clinical and educational interventions well in advance of starting transfer to adult care.
