Renal Abscess: Invasive Treatment or not

Objective To identify possible clinical indicators to guide the choice of treatment in patients with renal abscess. Methods According to different treatment methods, 38 patients initially diagnosed with renal abscess and received no prior treatment (antipyretics excepted) in our institution from April 2006 to November 2019 were divided into conservative treatment group and invasive treatment group, with the clinical data of all the cases being analyzed retrospectively. Results In the conservative treatment group, 19 patients got success and 1 failed in initial treatment, while in the invasive treatment group, 15 patients got success and 3 failed. Of the 4 patients who failed the initial treatment, 3 had a renal abscess between 3 cm and 5 cm, and 1 failed due to long-term use of bone marrow suppressive drugs. In univariate analysis, there were significant differences between the two groups in the following factors: diabetes mellitus, body temperature ≥ 38.5℃, PLT, RDW, BUN, PLR, AG, WBC in urine, size of abscess. In logistic regression analysis, diabetes mellitus, RDW and size of renal abscess were retained. The cut-off of RDW and size of renal abscess were 14.07% and 3.9 cm respectively. Conclusions Size of renal abscess is still the most important factor that determining treatment modalities. Other than size, high RDW and the comorbidity of diabetes mellitus may also be used as the possible clinical indicators for the determination of invasive treatment, especially in patients with renal abscess between 3 ~ 5 cm in size.
Incentives for Mothers, Health Workers and “Boda-Boda” Riders to Improve Community-Based Referral Process and Deliveries in the Rural Community: A Case of Busoga Region in Uganda

Background: This study set out to investigate how incentives for mothers, health workers and boda-boda riders can improve the community-based referral process and deliveries in the rural community of Busoga region in Uganda.Methods: The study was a 2-arm cluster non-randomized control trial study design; with intervention and control groups from selected health centres and communities as the units of non-randomization. The study interventions involved the provision of incentives for mothers, health workers and boda-boda riders for duration of six months. The study used a mixed methods research design with both quantitative and qualitative approaches. Descriptive statistical analysis was computed using STATA version 14 for the quantitative data and thematic analysis for qualitative data. Results: Findings revealed that incentives strongly improved community-based referrals and health facility deliveries in the study area. Mothers who delivered from health centres and transported by boda-boda transport were 70.5% in the intervention arm and only 51.2% in the control arm. Of the 70.5% of the mothers above, 69.4% were transported by trained boda-boda riders and only 30.6% were transported by un-trained boda-boda riders. The 69.4% mothers transported by trained boda-boda riders to health centres stated that boda-boda riders’ response to their calls for transport improved from 4.3% to 21.3% in the 5 – 20 minutes interval. For the 21 – 30 minutes interval, the response improved from 31.4% to 69.6% in the intervention arm compared to 37.1% to 40.3% in the control arm. As the time interval increased, the boda-boda riders who delayed to respond to mothers’ calls reduced. In the intervention arm, only 6.2% of the mothers stated that boda-boda riders’ response took 31 – 60 minutes time interval after the intervention compared to 54.9% before the intervention. There was little change in the control arm from 53.2% pre intervention to 41.2% post intervention. Similarly, the boda-boda riders’ response to mothers’ calls for transport reduced for the time interval of 60 minutes and above. Conclusion: Incentives and creation of partnerships are very critical in achieving better health facility-based deliveries as a result of proper referral processes.

Power quality disturbance detection and classification using wavelets and artificial neural networks

This article develops a method to detect and classify power quality problems using a novel combination of digital filtering, wavelets and artificial neural networks. The method is developed for voltage waveforms of arbitrary sampling rate and number of cycles, using a large variety of power quality events simulated with MATLAB(R) software, in addition to sampled waveforms from utility monitoring and EMTP(R) simulations. Power system monitoring, augmented by the ability to automatically characterize disturbed signals, is a powerful tool for the power system engineer to use in addressing power quality issues. This is a step toward the goal of automating the real-time monitoring, detection and classification of power signals.
Program CICC, flow and heat transfer in cable in conduit conductors

The computer program CICC has been written for use in the thermofluids design of superconducting magnets for tokamak reactors, which use forced-flow, helium-cooled, cable-in-conduit conductors (CICC). In addition to background heat loads that vary with space and time, these superconductors can develop normal zones that generate electrical resistance heat. Program CICC models the transient thermodynamic and fluid-dynamic system response to background heating and normal-zone propagation in the superconductor. The computational algorithm described couples a one-dimensional, compressible pipe-flow model (including flow choking) with two-dimensional, axisymmetric, heat-conduction models of the superconductor cable, the conduit and the epoxy-conduit insulation. National Institute of Standards and Technology helium properties are used. The model is verified by comparison with measured temperature and pressure profiles from thermal expulsion experiments. <<ETX>>

Two locations in Hanoi, Vietnam have been used for data collection, including exclusive motorcycle lane and undivided roadway. The passing characteristics in this research include (i) individual speeds and speed differences between passing and passed motorcycles; (ii) lateral spacing of passing and passed motorcycles; (iii) longitudinal distances from beginning and ending of passing event. For paired riding maneuvers, statistical analyses of speed and lateral spacing were revealed useful information. The threshold for paired riding including speed difference was also determined. The present study provides a comprehensive understanding of the characteristics of passing and paired riding maneuvers. These findings can be used to develop more accurate procedures for the analysis of the quality of service of motorcycle paths as well as to develop a comprehensive simulation model.
Recent Advances In Cs-Ba Tacitron Technology

The capability of the Cs-Ba tacitron as an inverter has been demonstrated, and its current modulation characteristics have been investigated. The inverter was operated in two modes, the thyratron (forced commutation) mode and the tacitron (grid controlled) mode. In the thyratron mode the tacitron was shown to modulate up to 10 kHz at a forward voltage drop as low as 2 V. In the tacitron mode, modulation frequencies up to 20 kHz at voltage drops of 3-3 5 V were demonstrated. The planar tacitron was shown to modulate 5 Ncm2 at 22 kHz, at a forward voltage drop of 2.2 V. Plasma diagnostic capability using Langmuir probes was sucessfully implemented.
INTEGRATING SOCIAL MEDIA AND DIGITAL MEDIA AS NEW ELEMENTS OF INTEGRATED MARKETING COMMUNICATION FOR CREATING BRAND EQUITY

Communication with target prospects results in a cost to the company. In this highly competitive environment, all marketers work on cutting cost. They try to allocate their marketing budget very carefully to create brand equity and achieve their marketing objective within the given budget. The selection of integrated marketing communication tools has become a problematic task for marketers. This paper provides how the integration of digital and social media within integrated marketing communication helps to create brand equity of the hospitality and tourism industry in India. This paper also examines the effectiveness of each IMC tool to create brand equity. The nonprobability convenience sampling technique was used to gather opinions from 512 tourists of Himachal Pradesh state of India. The findings reveal that both social media and digital media are more effective than traditional IMC tools. The study also found that the efficiency of Modern IMC tools is better than traditional IMC tools. Smart PLS-SEM 3.0 software has been used to scrutinise data and validate the conceptual framework.
Passive Intermodulation and Corona Discharge for Microwave Structures in Communications Satellites

As times goes by, satellite communication systems demand for higher component integration. Besides, an increase of services is also required, what implies the use of larger bandwidths. To achieve these objectives, the size of microwave devices on the one hand incessantly decreases whereas, at the same time, the power levels increase. Both trends lead to a higher electromagnetic field density inside the components. This development leads to serious problems with respect to RF breakdown (Corona Discharge and Multipactor) caused by high electromagnetic field densities, and cross-talking interference (Passive Intermodulation) due to bandwidth requirements. In this work, Passive Intermodulation (PIM) at waveguide flanges and Corona Discharge in microwave components, e.g. filters, are investigated. In both cases, theoretical research is developed in order to understand the physical mechanisms lying behind both phenomena. Results are presented which are useful for providing particular guidelines to avoid both effects in Sat-Com applications. Systematic experimental research for both phenomena is also presented along the thesis.
Certeze Village: The Dilemma of Traditional vs. Post-Modern Architecture in Țara Oașului, Romania

The traditional Romanian village has recently seen unmistakable transformations. The import of architectural styles from EU countries and the need to modernise dwellings, combined with considerable legislative voids regarding the protection of the built-up heritage, have strongly modified traditional architecture and resulted in irremediable losses in terms of rural authenticity and landscape aesthetics. This study aims to analyse the need for preserving existing traditional architecture in Certeze village, which has been severely jeopardised by the import of post-modern elements. The perception of both locals and tourists on these aspects was evaluated using the survey method. Results outlined more conservative views from the older inhabitants who are still attached to traditional constructing styles, while younger respondents preferred the more modern houses. Most tourists also showed an increased interest in the traditional architecture and criticised the newer constructed buildings. The contrast between old and new, which at this point is ubiquitous in the area, remains an element of intergenerational negotiations and risks the diminishing of the cultural authenticity of Certeze even further.
PC-SAN: Pretraining-Based Contextual Self-Attention Model for Topic Essay Generation

Automatic topic essay generation (TEG) is a controllable text generation task that aims to generate informative, diverse, and topic-consistent essays based on multiple topics. To make the generated essays of high quality, a reasonable method should consider both diversity and topic-consistency. Another essential issue is the intrinsic link of the topics, which contributes to making the essays closely surround the semantics of provided topics. However, it remains challenging for TEG to fill the semantic gap between source topic words and target output, and a more powerful model is needed to capture the semantics of given topics. To this end, we propose a pretraining-based contextual self-attention (PC-SAN) model that is built upon the seq2seq framework. For the encoder of our model, we employ a dynamic weight sum of layers from BERT to fully utilize the semantics of topics, which is of great help to fill the gap and improve the quality of the generated essays. In the decoding phase, we also transform the target-side contextual history information into the query layers to alleviate the lack of context in typical self-attention networks (SANs). Experimental results on large-scale paragraph-level Chinese corpora verify that our model is capable of generating diverse, topic-consistent text and essentially makes improvements as compare to strong baselines. Furthermore, extensive analysis validates the effectiveness of contextual embeddings from BERT and contextual history information in SANs.
Influence of insulating gas on pressure rise in electrical installations due to internal arcs

Internal arcs cause a rapid increase in pressure in electrical installations. The type of insulation gas has influence on pressure rise. Typically SF6 is used in compact metal-clad switchgear. This gas has a high global warming potential. Because of this the replacement of SF6 by alternative gases such as CO2 is under discussion. The pressure developments in a closed vessel filled with CO2, SF6 and air are measured and compared. During internal arcing in gas-insulated switchgear the overpressure causes a rupture of a burst plate and heated gas escapes into the surrounding room mixing with air. The portions of electric energy causing overpressure are therefore determined depending on gas density. To perform pressure calculations, reliable gas data and arc voltages are necessary. The arc voltages in the test vessel have been measured. CO2/air gas data are provided in a wide range of pressure and temperature. The thermodynamic properties are directly calculated from the number densities and from the internal partition functions. The transport coefficients are deduced using the ChapmanEnskog method.
Radiation pre-screening of 4 Mbit dynamic random access memories for space application

The authors present the results of a radiation pre-screening program carried out on eleven types of commercially available 4 Mbit DRAMs. This evaluation program covered total ionising dose and Single Event Upset/Latch-up (SEU/SEL) testing. The Cobalt-60 irradiation facility at ESTEC was used for the creation of the total ionising dose data and SEU/SEL data are presented using Californium-252, accelerator heavy ion and proton irradiation. The ESTEC 'CASE' facility was used for the verification of test hardware/software and to produce initial SEU/SEL cross section data. Further heavy ion testing was carried out covering a Linear Energy Transfer (LET) range of 0.6 to 54.0 MeV/(mg/cm2). Proton testing was carried out using energies of 30, 50, 100, 200 and 500 MeV. Details of these tests including test strategy, the memory tester used, test facilities and memory details are provided. <<ETX>>
A Review on the Some Issues of Multiphase Flow with Self-Driven Particles

Multiphase flow with self-driven particles is ubiquitous and complex. Exploring the flow properties has both important academic meaning and engineering value. This review emphasizes some recent studies on multiphase flow with self-driven particles: the hydrodynamic interactions between self-propelled/self-rotary particles and passive particles; the aggregation, phase separation and sedimentation of squirmers; the influence of rheological properties on its motion; and the kinematic characteristics of axisymmetric squirmers. Finally, some open problems, challenges, and future directions are highlighted.
Integration of hydrological and habitat simulation methods to define minimum environmental flows at the basin scale

New environmental policies establish the need to maintain the ecological integrity of freshwater ecosystems. The hydrologic regime is a key element in determining river processes and therefore the definition of environmental flow regimes (EFR) is essential to achieve this goal. The EFR can be broadly defined as the water required to sustain freshwater and estuarine ecosystems, and the human livelihood that depend on these ecosystems. Nevertheless, the role of the EFR and the methods to calculate them has not been clearly stated in many countries. This paper sets out a procedure to calculate EFRs, which includes not only a minimum flow, but also a temporal variability of this flow. The procedure integrates the results of hydrologic and habitat simulation methods in a temporal scale that takes into consideration the natural hydrologic seasonality while providing a certain level of flexibility to regulate water resources still meeting the requirements of the Spanish Water Planning legislation. The results highlighted the advantages of using different methodological approaches to calculate EFRs. Therefore, this study concludes the validity of a relatively simple hydrologic method for defining minimum environmental flows at a period of maximum hydrologic stress, but also the need to consider different approaches to take into account as many ecosystem elements as possible.
A Model of Millimeter-Wave Propagation for Personal Communication Networks in Urban Settings

Rapid development of personal, portable, radio communications is expected during this decade. A primary example of this is the emergence of personal communication networks (PCN). These networks are similar to today's cellular telephone technology. However, much smaller cell sizes are used and, as a result, the portable phone is much smaller (pocket size) and inexpensive. The use of millimeter waves for PCN services offers many advantages. Models of millimeter–wave propagation on the kinds of paths that will occur in small cells are needed. In this report a geometrical optics model of the propagation of millimeter waves for line–of–sight paths near street level in urban environments is developed. An idealized environment is assumed with flat streets and uniform street widths between flat building walls. The image–space approach is used to index the direct line–of–sight ray and all reflected ray paths between the transmitter and receiver. The model can be used to simulate received signal characteristics for testing system designs. The statistical behavior of signal level can be computed from the model for real world environments for which it is not practical to give a complete description of the complex physical geometry. The model also shows the channel impulse response functions to be expected in urban cells. Calculations from the model are compared with data measured in downtown' Denver at 9.6, 28.8, and 57.6 GHz.
Multidrug-resistant tuberculosis in Ho Chi Minh City: a retrospective study of 2,267 cases from 2011 to 2015

Background Multidrug resistant tuberculosis (MDR-TB) remains a serious public health problem with poor treatment outcome. Predictors of poor outcomes vary in different health-care settings. Vietnam is among the 30 countries with high burden of MDR-TB. We aim to describe demographic characteristics and identify risk factors for poor outcome of MDR-TB in Ho Chi Minh City (HCMC), the most populous city in Vietnam. Methods This retrospective study included 2,267 patients who initiated MDR-TB treatment from 2011 to 2015 in HCMC. Treatment outcomes were available in 2,241 patients. Data was collected from standardized paper-based treatment cards and electronic records. Statistical analysis was performed using R program. Results Among 2,267 eligible cases, 60.2% were failure of category I or II regimen, 57.7% were underweight, 30.2% had diabetes mellitus and 9.6% were HIV positive. Notification rate increased 24.7% from 2011 to 2015.Treatment success rate was 73.3%. Risk factors for poor treatment outcome included HIV co-infection (odds ratio (OR): 2.92), advanced age (OR: 1.47 for every increase of 5 years for patients older than 60), having history of MDR-TB treatment (OR: 5.65), sputum smear grade scanty and 1+ (OR: 1.48), smear grade 2+ or 3+ (OR: 2.07), low BMI (OR: 0.84 for every increase of 1kg/m2 of BMI for patients with BMI<21). Conclusion Our study describes the increasing burden of MDR-TB in HCMC and the need for better drug resistance screening for all TB patients. Patients with HIV, high smear grade, malnutrition and history of previous MDR-TB treatment should receive additional care.
