An Analysis of State-Owned Enterprise Holding Company Formation: The Case of Printing and Media Companies

This research aims to analyze the process of forming a holding company of state-owned enterprises in the printing and media business. This research uses qualitative research methods with a case study approach. The results of the study indicate that there are three options for printing and media holding company. The first option is printing and media holding with Perum Peruri as the holding company that will oversee four companies, namely Perum LKBN Antara, Perum PNRI, PT Balai Pustaka (Persero), and Perum PFN. The second option is printing holding and media holding. In printing holding, the holding company is Perum Peruri which will oversee one company, namely Perum PNRI. In media holding, the holding company is Perum LKBN Antara which will oversee two companies, namely PT Balai Pustaka Persero and PFN Public Corporation. The third option is the printing and media holding company with Perum LKBN Antara as a holding company that will oversee three companies, namely Perum PNRI, PT Balai Pustaka (Persero), and Perum PFN. At the same time, Perum Peruri will stand alone. The analysis indicates that the second option is the most appropriate in terms of logical roadmap and holding characteristics since printing (security printing) and media (distribution news) business are two distinct types of businesses.
Origin of superb electrical insulating capability of cellulose-liquid biphasic dielectrics by interfacial charge behaviors

The cellulose-liquid biphasic dielectric composite serves as the irreplaceable main electrical insulating structure in the power industry, owing to its peculiar high dielectric breakdown strength compared to that of monophasic cellulose paper or insulating liquid. Although this advanced electrical characteristic is utilized worldwide, its physical–chemical nature remains unclear, which greatly restricts the design and improvement of next generation electrical insulating composites. Herein, the interfacial charge behaviors in cellulose-liquid composites are investigated, and the results indicate that the majority of charge carriers in insulating liquid are electrostatically adsorbed at the nano-scale interface, forming interfacial charge traps, leading to 17.66 times increased deep trap density, which suppress further charge migration under high voltages, and consequently lead to the ∼400% improved dielectric breakdown strength compared to that of cellulose paper and insulating liquid. By controlling the interfacial trap characteristics with insulating liquids of strong electron withdrawing ability, the resistivity and breakdown strength of cellulose-liquid composites are further improved.
Global Dam‐Driven Changes to Riverine N:P:Si Ratios Delivered to the Coastal Ocean

River damming alters nutrient fluxes along the land‐ocean aquatic continuum as a result of biogeochemical processes in reservoirs. Both the changes in riverine nutrient fluxes and nutrient ratios impact ecosystem functioning of receiving water bodies. We utilize spatially distributed mechanistic models of nitrogen (N), phosphorus (P), and silicon (Si) cycling in reservoirs to quantify changes in nutrient stoichiometry of river discharge to coastal waters. The results demonstrate that the growing number of dams decouples the riverine fluxes of N, P, and Si. Worldwide, preferential removal of P over N in reservoirs increases N:P ratios delivered to the ocean, raising the potential for P limitation of coastal productivity. By midcentury, more than half of the rivers discharging to the coastal zone will experience a higher removal of reactive Si relative to reactive P and total N, in response to the rapid pace at which new hydroelectric dams are being built.

CARBONO ORGÁNICO EXTRAÍDO POR SOLUCIONES SALINAS Y SU RELACIÓN CON OTRAS FORMAS DE CARBONO DE SUELOS TROPICALES ORGANIC CARBON EXTRACTED BY SALINE SOLUTIONS AND ITS RELATION TO OTHER SOIL CARBON FORMS IN TROPICAL SOILS

Physical and chemical aspects were used to separate the soil organic matter in different fractions directly related to the dynamic of nutrients in the soil. To this end, a methodology to extract organic carbon (Corg) connected to the exchange sites of tropical soils was developed; selecting the best extractors, quantifying extracted C org from the exchangeable sites (Cext), and correlating it withothers C-forms. The soils were submitted to the extraction by K 2SO4, KNO3 and NaHSO4. Concentrations of water soluble carbon (WSC), mineralizable carbon (Cmin), oxidizable carbon (Coxid) and organic matter was fractioned in organic compounds of low molecular weight: fulvic and, humic acids and humin Neutral salts
Sucrose fatty acid esters: synthesis, emulsifying capacities, biological activities and structure-property profiles

Abstract The notable physical and chemical properties of sucrose fatty acid esters have prompted their use in the chemical industry, especially as surfactants, since 1939. Recently, their now well-recognized value as nutraceuticals and as additives in cosmetics has significantly increased demand for ready access to them. As such a review of current methods for the preparation of sucrose fatty acid esters by both chemical and enzymatic means is warranted and is presented here together with an account of the historical development of these compounds as surfactants (emulsifiers). The somewhat belated recognition of the antimicrobial, anticancer and insecticidal activities of sucrose esters is also discussed along with a commentary on their structure-property profiles.
Comparative Evaluation of Microscopy and Loop-Mediated Isothermal Amplification (Lamp) Assay for the Diagnosis of Tuberculosis

Tuberculosis (TB) is one of the major global health problem which affects millions of people each year. For the routine diagnosis of TB, microscopic technique is used but it has lower sensitivity and specificity. This study was carried out to evaluate the efficacy of loop mediated isothermal amplification (LAMP) over smear microscopy to detect Mycobacterium tuberculosis. Out of 84 processed samples processed in this study, the diagnostic tests showed varying results. Using smear microscopy, 16(19.05%) and with the LAMP assay, 17(20.24%) cases were found positive for M. tuberculosis. The sensitivity of the LAMP assay (87.5%) was greater than that of microscopy (82.35%) while the specificity of both methods was comparable (>95%). Being more sensitive than microscopy, LAMP assay is more likely to show the positive result and solve the errors in diagnosis of the TB cases. Thus, LAMP assay can be an important and cost-effective tool for appropriate and timely diagnosis of TB patients. This can further assist to implement intervention programs against TB.
The Construction of College Students’ Habit Guidance System based on Action Control Theory

In modern society with rich information, the behavior of college students born after the year 2000 shows new characteristics. In the face of temptations, as well as the significant differences in learning methods between universities and high schools, freshmen are prone to be confused and shaken in their self-control, which brings pressure of academic difficulties. In order to help freshmen quickly adapt to the university learning methods and develop good learning habits, based on the theory of behavior control, this paper constructs the habit guidance system of freshmen from three aspects: Students’ network behavior, work and rest habits, and reading interest. We achieved satisfactory results through two years’ practice in Beihang University.

Transit-induced Gentrification in Bangkok, Thailand: A Review

As many of the developing megacities, Bangkok has also implemented a TOD system to tackle the increase of traffic congestion and the availability of transportation issues. However, the TOD projects in Bangkok are not supported by an appropriate provision in affordable housing. In recent years, as the improved accessibility and transit proximity are often capitalized into housing and land prices, it resulted in the low-income population displacement, a condition that refers to the term transit-induced gentrification. This paper uses Bangkok, Thailand, as a case study to review the impact of TOD especially in the displacement of populations. The review concludes that the gentrification in Bangkok is initiated by the increase of the value and rent price of the property due to the presence of the transit station. The case in Bangkok is one of the precedents that have a combination of characteristics from the early period and the latest period definition of gentrification. It has the characteristics that the case is concentrated in the city center and the subject is working class and wealthy residents, which from the early definition. While it still represents the characteristics of the latest definition, such as indirect and direct displacement that appear at the same time.
PMU-Based Cable Temperature Monitoring and Thermal Assessment for Dynamic Line Rating

The aim of this paper is to present a novel phasor measurement unit (PMU) data-based cable temperature monitoring method with an intended application towards facilitating dynamic line rating. First part of the paper presents the method to estimate and track the temperature of a 3-phase cable segment. The benefit of this temperature monitoring method is that no additional temperature measurement sensors are required to be placed along the cable. The method is based on a novel algorithm which gives accurate resistance estimates for 3-phase cable segments even in the presence of random and bias errors in the grid measurements. The performance of the method is demonstrated by utilizing data from PMUs in a distribution grid. The results from the grid data show that the method is capable of monitoring the cable temperature up to an accuracy of $\pm$5 °C. The later part of the paper presents a system to utilize the temperature estimates given by the monitoring method to predict the dynamic thermal state of the cable for forecasted power-flow scenarios. This is demonstrated by using the available temperature estimates to initialize and solve the system of equations given by the thermoelectric equivalent (TEE) model of the cable.
Factors that Affect Network Formation in Carbon Nanotube Composites and their Resultant Electrical Properties

This review paper explores the formation of carbon nanotube (CNT) polymer composites as a function of material and processing parameters. The effect of different polymer systems, increasing multiwall CNT content, modification of CNTs, processing conditions, and aspect ratio are discussed in detail for multi-walled carbon nanotubes (MWCNT) composites along with some examples for SWCNT composites. All of these factors influence the microstructure and how the network of CNTs forms within it. Often, researchers choose to modify the CNTs to aid in their distribution; however, this may result in a reduction or increase in conductivity depending on many factors. The electrical properties are directly affected by changes in the CNT network and how the material has been processed. As soon as the network forms, percolation occurs and the conductivity increases. In order to understand how to control the properties of CNT composites, all material characteristics and processing conditions must be taken into account.
Anomalous distribution of distinctive water masses over the Carlsberg Ridge in May 2012

Abstract. In May 2012, we conducted a hydrographic survey over the Carlsberg Ridge in the northwest Indian Ocean. In this paper, we use these station data, in combination with some free-floating Argo profiles, to obtain the sectional temperature and salinity fields, and subsequently, the hydrographic characteristics are comprehensively analyzed. Through the basic T–S diagram, three salty water masses, Arabian Sea High-Salinity Water, Persian Gulf Water, and Red Sea Water, are identified. The sectional data show a clear ventilation structure associated with Arabian Sea High-Salinity Water. The 35.8 psu salty water sinks at 6.9 ∘ N and extends southward to 4.4 ∘ N at depths around the thermocline, where the thermocline depth is in the range of 100 to 150 m . This salty thermocline extends much further south than climatology indicates. Furthermore, the temperature and salinity data are used to compute the absolute geostrophic current over the specific section, and the results show mesoscale eddy vertical structure different from some widely used oceanic reanalysis data. We also find a west-propagating planetary wave at 6 ∘ N, and the related features are described in terms of phase speed and horizontal and vertical structures.
Early Neuroendoscope-assisted Evacuation of Spontaneous Intracranial Hematomas. Preliminary Report

Purpose: The surgical techniques, effectiveness and indications of microsurgical neuroendoscopic assisted evacuation of spontaneous intracranial hematomas (SICH) is still uncertain. This minimal invasive technique remains investigational and controversal with regard to patient selection, timing of operation and method of the management. The purpose of this study was to investigate the early postoperative results in patients with SICH underwent endoscopic evacuation and to give evaluation and eventual prognosis of the clinical outcomes after this procedure. Material and Methods: A retrospective analysis of 56 patients SICH treated in the Neurosurgical clinic with endoscopic assisted evacuation was performed. Hematoma volume and its localization (subcortical – 11 patients, in basal ganglia – 12 – 7 of them with propagation to ventricular system, 6 infratentorial and 27 subdural), comorbidity, clinical features and timing of surgical procedures was made. The GCS rate by admission and GOS by discharging of patients was analyzed, also the postoperative complications and causes of death. Results: 52 patients (92, 9%) were operated within the first 24 hours of the onset. Patients operated between the 12 and 24 hours had better outcome in comparison to these operated after the 24 hours period. The authors analyzed their experience with endoscopic technique, effectiveness of the method, results and complications. Mortality rate in our series was 23, 2% (13 patients). The causes of surgical complications and causes of death were analyzed. Conclusion: The endoscopic assisted evacuation of SICH is a short, safe and very effective method when the surgical procerure is provided within the first 12–24 hours. Our results showed that early and complete evacuation of hematoma volume may promote to recovery of the general condition of the patient and improved outcomes.
Analytical Treatment of Normal Condensation Shock

The condensation of water vapor in an air consequences: acquisition of heat (liberated heat vaporization; loss of mass on the part of the flowing gas (water vapor is converted to liquid); change in the specific gas constants and of the ratio k of the specific heats (caused by change of gas composition). A discontinuous change of state is therefore connected with the condensation; schlieren photographs of supersonic flows in two-dimensional Laval nozzles show two intersecting oblique shock fronts that in the case of high humidities may merge near the point of intersection into one normal shock front.
Implementation of crop growth monitoring system based on depth perception using stereo camera in plant factory

The plant factory is extensive cultivation to produce a high quality of vegetables under a controllable environment. The concept of Precision Agriculture (PA) was introduced to improve the plant factory production by the implementation of a crop growth monitoring system. Crop growth can be estimated by monitoring of crop height and canopy foliage by the use of computer vision technology. In our previous study, we have introduced a plant height monitoring system based on depth perception using a stereo camera. However, the validity of the various type of leave is necessary to be tested. The objective of this study was to implement the crop growth monitoring system to monitor plant development with various type of leave for system validation and evaluation. The crop growth monitoring system composed of a stereo camera implementing the depth perception for estimating the distance from camera to highest point in the crop. The implementation of the system with various types of leaves and characteristics has been conducted for (a) Samhon, (b) Lettuce, and (c) Pagoda. The developed crop growth monitoring system could perform the time series estimation of crop height with a maximum error of RMSE 0.875 cm on Pagoda, and MAPE of 5.56% on Lettuce. The system demonstrates better estimation on Samhong with minimum error RMSE of 0.408cm and 2.27 % of MAPE. Overall validation for the estimated height vs actual measurement indicates that the coefficient of determination higher than 0.7 means that it has substantial features for estimating the plant height.
Optimal Design of Isolated Mini-Grids with Deterministic Methods: Matching Predictive Operating Strategies with Low Computational Requirements

The lack of electricity access is increasingly concentrated in rural areas of developing countries, in which mini-grids are often a suitable solution; however, given the high risks, it is crucial to minimize costs. This paper aims at analyzing existing methodologies for the optimal design of mini-grids combined with different operating strategies. Typical system operations, like the load-following (LFS) and cycle charging (CCS) strategies, are compared with the more demanding predictive strategies based on Mixed-Integer Linear Programming (MILP). The problem is formulated and solved with Particle Swarm Optimization (PSO), so to simulate traditional and predictive operating strategies. Two reformulations based on the proposed Search Space Update are also detailed and compared with the so-called one-shot MILP model, which is able to con-jointly optimize both the design and the operation of the system, in order to reduce computational requirements with the predictive strategy. The results, tailored with data from a rural mini-grid in Kenya, highlight that heuristic methodologies can perform better than the traditional MILP approach, both in terms of optimality and computational time, especially when advanced operating strategies are considered. Conventional operating strategies (LFS or CCS) appear to be sub-optimal, but require very little computational requirements, which makes them suitable for preliminary designs.
Source Process for Two Enigmatic Repeating Vertical‐T CLVD Tsunami Earthquakes in the Kermadec Ridge

Two repeating compensated linear vector dipole (CLVD) earthquakes occurred in 2009 and 2017 on the Kermadec Ridge near the Curtis submarine volcano. The tsunami and seismic waveforms of both events are almost identical. Simulated tsunami and seismic waveforms are compared with observations of the 2017 event to estimate the location and geometry of the source. A CLVD source model at 8–14 km depth is consistent with the global CMT solution but generates no tsunami. The tsunami waveforms can be well reproduced if the source model is about 1.5 km deep. However, a seismic source at this depth is not consistent with the observed seismic waves. This suggests that two sources were involved with different depths. The main, shallow, tsunami source could be due to hydrofracturing of heated water in a shallow sediment layer triggered by a deeper earthquake.
Flood Risks in Sinking Delta Cities: Time for a Reevaluation?

Sea level rise (SLR) and subsidence are expected to increase the risk of flooding and reliance on flood defenses for cities built on deltas. Here, we combine reliability analysis with hydrodynamic modeling to quantify the effect of projected relative SLR on dike failures and flood hazards for Shanghai, one of the most exposed delta cities. We find that flood inundation is likely to occur in low‐lying and poorly protected periurban/rural areas of the city even under the present‐day sea level. However, without adaptation measures, the risk increases by a factor of 3–160 across the densely populated floodplain under projected SLR to 2100. Impacts of frequent flood events are predicted to be more affected by SLR than those with longer return periods. Our results imply that including reliability‐based dike failures in flood simulations enables more credible flood risk assessment for global delta cities where conventional methods have assumed either overtopping only or complete failure.
Characterization of Combustion Synthesis of Ferromagnetic FeAl2O4 spinel

intriguing fundamental properties and potential applications. Spinel with general formula AB2O4 and FCC structure is typical of such interest [1-2]. Several synthesis methods for these materials have been proposed, including co-precipitation, sol-gel [3], and combustion reaction synthesis [4]. The last is particularly convenient because of its low costs, high-reaction speed, and also energy efficient as the reaction release energy, which is contrary to other techniques mentioned [5]. In this work we synthetize
