Improvement of the input performance of a three‐phase‐single‐phase matrix converter based on space vector modulation

A 6‐switch three‐phase to single‐phase matrix converter (3‐1MC) with independent neutral line is directly coupled to the input side through bidirectional switches, and the output ripple power produces low‐frequency harmonics in the input side that are difficult to filter out. In this paper, the expressions of the frequencies and contents of the low‐frequency harmonics are derived based on the principle of input‐output instantaneous power conservation. Then, a 3‐1MC topology with decoupling unit is studied and the working principle and process of improving the input performance are analyzed. Second, based on the relationship between the output side and the decoupling side modulation function, the influence of the introduction of the decoupling unit on the maximum voltage transfer ratio of 3‐1MC is studied. The relationship between the voltage transfer ratio and parameters such as decoupling unit and output frequency is derived in detail. It is proved that maximum voltage transfer ratio of the topology is a nonlinear function related to system parameters. Then, the operating principle and modulation method of 3‐1MC are discussed. A double‐side current closed‐loop control strategy based on space vector modulation under power decoupling conditions is proposed. Finally, an experimental platform is built to verify that the 3‐1MC with decoupling unit can suppress the low‐frequency harmonics in the input current at different output frequencies and effectively improve the performance of the input side. The results show that the 3‐1MC with the decoupling unit is beneficial for use in single‐phase applications.
In vivo microstimulation with cathodic and anodic asymmetric waveforms modulates spatiotemporal calcium dynamics in cortical neuropil and pyramidal neurons of male mice

Electrical stimulation has been critical in the development of an understanding of brain function and disease. Despite its widespread use and obvious clinical potential, the mechanisms governing stimulation in the cortex remain largely unexplored in the context of pulse parameters. Modeling studies have suggested that modulation of stimulation pulse waveform may be able to control the probability of neuronal activation to selectively stimulate either cell bodies or passing fibers depending on the leading polarity. Thus, asymmetric waveforms with equal charge per phase (i.e. increasing the leading phase duration and proportionately decreasing the amplitude) may be able to activate a more spatially localized or distributed population of neurons if the leading phase is cathodic or anodic, respectively. Here, we use two-photon and mesoscale calcium imaging of GCaMP6s expressed in excitatory pyramidal neurons of male mice to investigate the role of pulse polarity and waveform asymmetry on the spatiotemporal properties of direct neuronal activation with 10 Hz electrical stimulation. We demonstrate that increasing cathodic asymmetry effectively reduces neuronal activation and results in a more spatially localized subpopulation of activated neurons without sacrificing the density of activated neurons around the electrode. Conversely, increasing anodic asymmetry increases the spatial spread of activation and highly resembles spatiotemporal calcium activity induced by conventional symmetric cathodic stimulation. These results suggest that stimulation polarity and asymmetry can be used to modulate the spatiotemporal dynamics of neuronal activity thus increasing the effective parameter space of electrical stimulation to restore sensation and study circuit dynamics. Significance Statement Electrical stimulation has promise to restore sensation and motor function, as well as treat the symptoms of several neurological disorders. However, the mechanisms responsible for the beneficial effects of stimulation are not fully understood. This work supports modeling predictions by demonstrating that modulation of the stimulation waveform dramatically affects the spatial recruitment and activity level of neurons in vivo. These findings suggest that stimulation waveform symmetry represents a parameter that may be able to increase the dynamic range of stimulation applications. Further characterization of these parameters with frequency, and amplitude could provide further insight into the mechanisms of electrical stimulation.
Supporting Advanced Practice Provider Transition to Practice: A Theoretical and Evidence-Based Intervention

New graduate nurse practitioners and physician assistants, also known as advanced practice providers (APPs), face a significant number of challenges when entering professional practice. If the new graduate does not receive sufficient guidance and support during this transition to practice (TTP), they will likely experience significant psychological stress and anxiety. If an organization does not implement measures to address TTP, the new graduate is much more likely to leave the current position within the first two years of practice. An extensive literature review was conducted investigating the effects, and necessary components of an orientation program which supports the new graduate through TTP. Using Van Maanen & Schein’s (1979) Theory of Organizational Socialization, a comprehensive new graduate orientation program was designed and implemented in large multi-specialty practice. Initial results suggest that this program improves both the perceived organizational support felt by the new graduate, as well as the new graduates’ affective commitment to the organization. Improvements in both these dimensions have been shown to decrease turnover intention and increase retention of the employee.
Assessment of efficacy and safety of praziquantel in the treatment of Schistosoma haematobium in school-aged children, Ogun State, Nigeria

Praziquantel (PZQ) remains the drug of choice for treatment of schistosomiasis in infected persons. This study assessed the efficacy and safety of PZQ in school-aged children in four communities’ endemic for schistosomiasis. Urine samples (10 ml) were collected from 300 primary school children aged 5-16 years in Ibaro Oyan, Imala Odo, Apojola and Abule Titun communities located in parts of Ogun State, Nigeria. The urine was examined for the presence of haematuria and ova of S. haematobium . All pupils were also treated with a single dose of PZQ at 40 mg/kg. Urine samples were collected from positive pupils 21 days later to determine the Cure Rate (CR) and Egg Reduction Rate (ERR). Survey forms were also used to collect information on safety of the drug, documenting observed adverse reaction. Results showed that prevalence by haematuria was 147 (69%). Assessing haematuria with ova of S. haematobium revealed that 132 (44%) were positive for haematuria using dip-stick and eggs of S. haematobium simultaneously. Two hundred and nine pupils (69.7%) were infected with S. haematobium with mean egg count of 16.23 eggs/10 ml of urine. Males (73%) were more infected than females (66.7%). The highest prevalence (72.8%) was observed among the age-group 9-12 years and the least prevalence among age-group 5-8 years. The presence of S. haematobium was neither age nor sex dependent ( p >0.05). On location and intensity, school children located in Imala Odo Community had the highest prevalence of 89.2%, but pupils in Ibaro had the highest Geometric Mean (GM) of 18.31 eggs/10 ml. At 21 days post-treatment the cure-rate (CR) was 96.1%. The anthelminthic drug Praziquantel efficacy was satisfactory with an Egg Reduction Rate (ERR) of 98.5%. Most of the adverse effects occurred within 4-24 hours after PZQ administration but abdominal pains were the most common adverse visible micro effects complained by the school-children.

The use of 1H-magnetic resonance spectroscopy in studying radiation-induced injury of the brain in elderly and young patients with nasopharyngeal carcinoma

Background: This study aims to inves gate the metabolic characteris cs of radiotherapy-induced temporal lobe injury in elderly pa ents with nasopharyngeal carcinoma using 1 H-magne c resonance spectroscopy (MRS). Materials and Methods: Data were collected from 21 elderly pa ents and 33 young pa ents before and during therapy with different radia on dosages (20, 40, and 60 Gy). The Student’s t-test was used to compare the 1H -MRS-based N-acetyl aspartate /Crea ne (NAA/Cr), Choline/Crea ne (Cho/ Cr), and NAA/Cho ra os in the temporal lobes. Results: Sta s cally significant differences in the NAA/Cr and NAA/Cho ra os was found between the two groups (P < 0.05) at 20, 40, and 60 Gy. The Cho/Cr ra os (20/40/60 Gy) were 1.82 ± 0.16/1.61 ± 0.29/1.37 ± 0.13 and 1.77 ± 0.19/1.48 ± 0.17/1.06 ± 0.14 in the elderly and young pa ents, respec vely. We found significant differences between the two groups at the dosages of 40 and 60 Gy (P<0.05). The decrease in the NAA/Cr and NAA/Cho ra os in the elderly group was significantly higher than that in the young pa ents with dosages of 20, 40, and 60 Gy. The decrease in the Cho/Cr ra o in the elderly group (2.15%/11.29%/12.90%) was significantly lower than that in the young pa ents (3.30%/15.93%/17.58%). Conclusion: Under the same radiotherapy pa<ern and radia on dosage, the injury to the neurons in the temporal lobes was significantly greater in elderly pa ents than that in young pa ents. The interven on conducted in elderly pa ents at a dosage of 20 Gy might help minimize the injury to the neurons.
Accommodations for the inclusion of children with disabilities in regular schools in Trinidad: a mixed methods approach

ABSTRACT This paper examines the accommodations for the inclusion of children with disabilities in regular schools in Trinidad. A multiphase mixed methods design consisting of three phases is used. In the first phase, the environmental accommodations essential for the inclusion of children with disabilities in schools are identified. This information is obtained through interviews with parents and advocates of children with various disabilities. Five themes emerge, namely, qualified human resources, educational materials, physical access, supportive learning systems, and supportive school policies and rules. A questionnaire is then developed in the second phase based on these qualitative findings which is administered to a representative sample of primary and secondary schools in the third phase. Qualitative data are also collected in the third phase. Particularly, data on inclusive education policy are collected from primary and secondary schools and data on legislation supporting inclusion from government officials. The integrated findings indicate that existing environmental accommodations, law, and policy do not fully support the inclusion of children with disabilities in Trinidad. They further illustrate the need for national discourses to move beyond access to maximum participation, and for stronger legislation to ensure inclusion in schools.
A study on dermatological manifestations among chronic kidney disease patients undergoing hemodialysis in a tertiary care centre

Background: Chronic kidney disease (CKD) is a progressive loss of kidney function over a period of months or years through five stages. The prevalence of end-stage renal disease (ESRD) in India is increasing with an estimated annual incidence of about 100 per million populations. About 50-100% of patients with ESRD have at least one associated cutaneous change. These cutaneous disorders can precede or follow the initiation of hemodialysis treatment, and there are more chances to develop newer skin changes during the course of hemodialysis therapy, which may affect the quality of life. Objectives of the study was to find out the prevalence of various dermatological manifestations in patients undergoing hemodialysis in a tertiary care centre. Methods: A cross sectional study was carried out in the general medicine department of a tertiary care Centre. All cases of chronic kidney disease were diagnosed according to the criteria of KDQQI CKD guidelines, age group between 30-60 years are included. Pediatric patients with chronic kidney disease, patients who had renal transplantations, patients on peritoneal dialysis and renal injury patients are excluded. Results: Out of the 100 study participants majority are males (60%). Majority of the patients belongs to lower socioeconomic status family (59%). Atleast one dermatological manifestation was present in all patients. 23% of the patients presented with two dermatological manifestations and 22% of the participants had three or more dermatological manifestations. Xerosis was the most common dermatological manifestation present among the patients. Conclusions: This study reflects that quality of life in dialysis patients is mainly depend on timely recognition and prompt management of these dermatological conditions.

Cardiorespiratory and muscular endurance of sedentary children and adolescents with or without intellectual disability in the Democratic Republic of Congo

The aim of this study was to assess the level of physical fitness and sedentary children with disabilities included in Kinshasa. One hundred-thirty children were included in this study, 70 with intellectual disability (ID, age: 12.4 ± 4 years) and 60 without ID (age: 11.6 ± 4 years). Flexibility, explosive strength, grip strength, abdominal endurance, and cardiorespiratory endurance tests were used. They are supplemented by the measurement of anthropometric characteristics. Measurements of muscular strength endurance, isometric force, walking distance and cardiorespiratory endurance was significantly higher in comparison with ID (p<0.05). The muscular strength endurance, isometric strength walking distance and cardiorespiratory endurance of girls was significantly lower than those of the control group (p <0.05). It is clear from this study that the cardiorespiratory and muscular endurance of children and adolescents with intellectual disabilities is inferior to those of children without intellectual disabilities regardless of the type of children.
Effect of the data lenght and seasonality on the accuracy of T-year discharges estimation: Case study on the Topľa River

The paper deals with the effect of two factors on the accuracy of T-year discharge estimation resp. fluctuations in the estimation of these discharges. As input data the series of daily discharges and peak discharges on the Topľa River at Hanušovce nad Topľou for the period of 1931–2015 were used. To estimate the T-year maximum discharges, the maximum annual discharges (AM) method was used with theoretical probability distributions that are among the most widely used in Slovak hydrological practice (Log-Pearson III, Gamma and Log-Normal). We analysed the effect of the time series length and the effect of seasonality (winter, summer) on the accuracy of T-year maximum discharges estimation.

WCC 2017-C-103: Emergency Surgical Retrieval of Embolized Atrial Septal Defect Closure Device from Left Atrium

Abstract With the introduction of technological improvements, invasive cardiologic interventions have become increasingly used alternatives to surgery. Despite its numerous benefits, serious and potentially life-threatening complications of invasive cardiology interventions may occur. Atrial septal defect is usually closed in the cardiac catheterisation laboratory using atrial septal occluder (ASO) device. One of the complications associated with the procedure is dislodgement of the device. We present a case of percutaneous trans catheter closure of an ostium secundum atrial septal defect in a 21 years old female, complicated by device dislodgement to the left atrium necessitating emergency surgical retrieval.
The Quantified Indices for Compensatory Patterns for Low Back Pain and Outcome Measures

The quantification of balance stability is valuable to a number of populations, including older adults with low back pain (LBP). Investigations into postural stability and one‐ leg standing should be performed to integrate balance performance using kinematic and kinetic indices. The comparison of postural control between older adults with LBP and healthy older adults might contribute to a further understanding of postural adap‐ tations, especially when considering visual condition. The one‐leg standing test would highlight the differences in kinematic and kinetic stabilities between groups. Because the eyes‐closed condition results in significantly decreased spinal stability, the normalized kinematic and kinetic indices could be utilized to compare postural integration as well as proprioceptive responses. Older adults with LBP demonstrated higher lumbar spine sta‐ bility in the eyes‐open condition, which might be due to a possible pain avoiding strategy from the standing limb. Clinicians need to consider both kinetic and kinematic indices and visual condition when addressing lumbar spine stability. Quantified indices for com‐ pensatory patterns might provide further understanding of optimal injury prevention and rehabilitation strategies for individuals with LBP.
To analyse the success rate of external Dacryocystorhinostomy related with anatomical osteotomy size made during surgery

Introduction: Dacryocystorhinostomy (DCR) surgery failure is usually due to the closure of the surgical osteotomy. Creation of a large osteotomy helps to increase the chances of success of surgery. Objective: To evaluate the size of osteotomy made during surgery and its correlation with successful DCR surgery. Methodology: A retrospective review of 50 patients (19 males, 31 females) more than 10 years of age, over a period of 24 months were done. The External DCR surgery was performed by ophthalmic surgeon in patients of chronic dacryocystitis or after resolution of acute inflammation. All patients were operated by same technique of local anesthesia and nasal packing. Curvilinear skin incision 7-8 mm from medial canthus. Cutting of medial palpebral ligament. Identification of lacrimal sac and fossa. Creating large bony ostium by direct visualization. Measuring and recording of size of ostium using sterile measuring caliper. Suturing of anterior mucosal flaps. Retrospective data collection included the patient’s age, sex, affected side, symptoms, operative experience, and follow-up results. Results: Complete Patency in 49 (98%) patients and Partial Patency in 01 (2%) patient. Overall success rate of Ext. DCR surgery is 92-94% with complete relief from epiphora achieved in 90% of cases. Conclusion: The successful DCR surgery requires a Big Osteotomy size with a mean value of 1.2cm±0.3 SD which differs from patient to patient according to sac size and bone, along with meticulous surgery and proper identification of structures and tight apposition of anterior mucosal flaps.
