Published: August 2019

In this study, Fuzzy-Fractional Order Proportional Integral Derivative (Fuzzy-FOPID) control technique is applied to regulate the speed of a separately excited DC motor. This control technique uses a combination of two intelligent algorithm tuning methods, Fuzzy logic and Genetic Algorithm (GA). This is done to get an effective and powerful control effect. The identification of parameters in the form of Kp, Ki and Kd uses fuzzy logic and for fractional parameters in the form of μ and λ using GA. To find out the performance of this control technique several tests have been carried out using the MATLAB 2013a simulation which then the results are compared with Fractional-Order PID (FOPID) control technique where all parameters are obtained using GA tuning. In testing the speed and constant load the performance of the Fuzzy-FOPID control has a smaller overshoot value and the settling time is faster than the FOPID control. The FOPID driver has a better undershoot response of 0,25% when there is a change in the added load. But when testing the speed change, Fuzzy-FOPID control has a fast and stable response with an undershoot value of 0.875% and a 0.143% overshoot, smaller than the FOPID control. From the results of all tests, it can be concluded that Fuzzy-FOPID control is better and more efficient than FOPID control.Dalam penelitian ini, teknik kendali Fuzzy-Fractional Order Proportional-Integral-Derivative (Fuzzy-FOPID) diterapkan untuk mengatur kecepatan motor DC penguat terpisah. Teknik kendali ini menggunakan gabungan dua metode penalaan algoritma cerdas yaitu logika fuzzy dan Algoritma Genetika (GA). Hal ini dilakukan untuk mendapatkan efek kendali yang efektif dan kuat. Penalaan parameter Kp, Ki, dan Kd menggunakan logika fuzzy dan untuk parameter fractional μ dan λ menggunakan GA. Untuk mengetahui kinerja dari teknik kendali ini telah dilakukan beberapa tes menggunakan simulasi MATLAB 2013a yang kemudian hasilnya dibandingkan dengan teknik kendali lain yaitu teknik kendali FOPID dimana semua parameternya didapat dengan menggunakan penalaan GA. Pada pengujian kecepatan dan beban konstan performa kendali Fuzzy-FOPID memiliki nilai overshoot yang lebih kecil dan settling time lebih cepat dibanding kendali FOPID. Pengendali FOPID memiliki respon undershoot yang lebih baik sebesar 0,25 % ketika tejadi penambahan beban. Namun ketika dilakukan pengujian perubahan kecepatan, kendali Fuzzy-FOPID memiliki respon yang cepat stabil dengan nilai undershoot 0,875 % dan overshoot 0,143%, lebih kecil dibandingkan dengan kendali FOPID. Dari hasil seluruh pengujian dapat disimpulkan bahwa kendali Fuzzy-FOPID lebih baik dan effisien dibandingkan dengan kendali FOPID.

Published: August 2019

The ability of bismuth to maneuver between different oxidation states in a catalytic redox cycle, mimicking the canonical organometallic steps associated to a transition metal, is an elusive and unprecedented approach in the field of homogeneous catalysis. Herein we present a catalytic protocol based on bismuth, a benign and sustainable main-group element, capable of performing every organometallic step in the context of oxidative fluorination of boron compounds; a territory reserved to transition metals. A rational ligand design featuring hypervalent coordination together with a mechanistic understanding of the fundamental steps, permitted a catalytic fluorination protocol based on a Bi(III)/Bi(V) redox couple, which represents a unique example where a main-group element is capable of outperforming its transition metal counterparts.A main text and supplementary material have been attached as pdf files containing all the methodology, techniques and characterization of the compounds reported.
Um Tesouro da Cultura Ocidental

Este artigo tem por objetivo tecer algumas considerações relativamente aos três manuscritos medievais que se encontram na Biblioteca Central (BCE) da Universidade de Brasília (UnB), a saber: Diálogos de S. Gregório, Vidas de Santos e Livro das Aves. Esses manuscritos tiveram origem no universo do livro religioso medieval em território português. Esta é uma característica fundamental neste património, isto é, o da sua condição e dependência do universo cultural do medievo português, universo em que o religioso, como por todo o Ocidente cristão, ocupa o lugar central. Os manuscritos medievais da UnB não intermedeiam um texto originariamente em latim, mas antes um texto traduzido em língua portuguesa para melhor compreensão dos leitores a que se destinavam, no caso, e, sobretudo, um público clerical, regular ou secular, mas sem eliminar o acesso de possíveis utilizadores leigos.

Background. Primary inferior oblique muscle overaction (PIOOA) may occur for various reasons and happens to 72 % patients with infantile esotropia. The criterion for the first surgical step is prevalence of vertical or horizontal deviation. The choice of tactics weakening inferior oblique muscle is ambiguous.Aims: to carry out retrospective analysis of PIOOA frequency in patients with infantile esotropia; to assess influence of esodeviation reduction by a surgical, chemodenervational or prismatic method on the existing PIOOA dynamics; to assess clinical and functional results of PIOOA treatment.Methods and methods. The retrospective analysis of 572 patients’ cases lay in assessment of PIOOA frequency and rate in patients with infantile esotropia that manifested under 9 months, with different treatment tactics. The prospective part of the research included two groups of patients. Group 1 (106 patients, 222 eyes) – studying the influence of surgical treatment of PIOOA. Group 2 (127 patients, 207 eyes) – studying the effectiveness of surgical PIOOA treatment. Conclusion. PIOOA frequency in case of different treatment tactics for patients with infantile esotropia is from 17 to 69 %, and the degree of its clinical manifestation is from 1.2 ± 0.4 to 2.6 ± 0.8. Bilateral weakening of medial rectus muscle reduces its probability up to 17–19 %, and the degree of its manifestation up to 1.2 ± 0.4. In cases of combination of PIOOA with infantile esotropia from 20 to 25° with paretic component, it is reasonable to carry out esodeviation reduction by means of bilateral recession, chemorecession or prismatic correction as the first treatment stage, whereas the rate of existing PIOOA is credibly reduced. In cases of choice of tactics, which is necessary for clinically significant reduction or elimination of PIOOA, it is reasonable to carry out chemorecession, marginal partial myotomy or myectomy depending on the PIOOA manifestation.

Aim. To modify the calculated parameters of the lenticle extraction refractive surgery through a small access (SMILE), evaluate its safety and clinical efficacy in correcting high myopia.Materials and methods. 34 patients (68 eyes) underwent surgery by a modified SMILE technology under local anesthesia. In all cases, the patients had a high degree of myopia, in 37 % in combination with astigmatism.Uncorrected visual acuity before surgery averaged 0.05 ± 0.11, best corrected visual acuity of 0.94 ± 0.1, the pre-operative spherical refraction component was –7.23 ± 0.75, the cylindrical component was –0.48 ± 0.59.During the operation, to obtain the maximum possible refraction result using the proposed method, the standard operation parameters were changed: the corneal flap thickness was reduced to 100 μm, the neural optical layer by 5 μm, the diameter of the optical zone depended on the residual cornea thickness, which should exceed 280–290 μm. Corneal access was increased by 15–20 degrees.Results. The next day after surgery, monocular uncorrected visual acuity in distance in 73 % of patients was 0.8 or higher, and in 41 % of cases it was equal to or exceeded 1.0. The spherical equivalent on the first day after surgery had a slight hypermetropic shift, which was completely leveled by the year of follow-up. During the surgical intervention and in the postoperative period, no complications were noted.Conclusion. Using the proposed algorithm for calculating the refractive effect of the operation SMILE with a high degree of myopia allows obtaining a high refractive effect and avoiding possible complications.

Modern surgical treatment of cataracts provides effective results. The study of the position of the intraocular lens (IOL) in the capsule bag can be considered as one of the most important factors influencing the final visual and refractive result of the operation.Aim: comparative analysis of clinical and functional results and position of the IOL in the capsular bag, namely decentration and tilt, when performing femtolazer-assisted phacoemulsification (FLACS) and standard phacoemulsification (CPCS). Materials and methods. We surveyed 57 patients (57 eyes). FLACS was performed in 27 patients, CPCS – in 30 patients. Standard methods of research were used, determination of the position of the IOL (decentration and tilt) in the capsular bag on the device OCT-Casia2 (TOMEY, Germany) and study of wave front were conducted.Results. Comparative analysis of the obtained results showed no significant difference between groups in postoperative visual acuity, however, there was the trend towards higher performance corrected distance visual acuity and uncorrected distance in the group FLACS (0.68 ± 0.18 and 0.74 ± 0.2) compared to the group CPCS (0.58 ± 0.28 and 0.65 ± 0.24). Internal higher order aberrations were significantly low in the group with femtolazer accompaniment: in 3 mm zone almost 2 times (p = 0.041), in 5 mm zone 1.3 times (p = 0.047). Vertical decentration in a CPCS group made 0.217 ± 0.26 mm, in FLACS group – 0.118 ± 0.05 mm, the vertical tilt – 0.75 ± 0.37° and 0.54 ± 0.36 respectively. Conclusion. Decentralizations and IOL tilt tended to lower indices in the FLACS during the observation period up to 2 months after the operation, which was accompanied by lower values of higher order internal aberrations.

Retinal vein occlusion is one of the most severe vascular lesions of the organ of vision, usually accompanied by somatic pathology.The aim of the study was to study the somatic status and individual biochemical markers in patients with retinal vein occlusion and comparison in groups opposing the effectiveness of anti-VEGF therapy.Methods. 84 patients with macular edema were examined on the background of retinal vein occlusion, who underwent intravitreal injections of an angiogenesis inhibitor for therapeutic purposes. Further, depending on the effectiveness of treatment, the patients were divided into 2 groups, in which a retrospective comparative analysis of somatic status and laboratory data was performed.Results. It was shown that patients with occlusion of the retinal veins have significant impairments in terms of somatic status, blood biochemical parameters and coagulogram. Moreover, there is a direct relationship between the severity of somatic changes and ocular manifestations of the disease. The data obtained reflect a clear tendency in patients with occlusion of the retinal veins to a high risk of cardiovascular complications, including occlusive lesions. In patients with an insufficient treatment effect, a more severe course of arterial hypertension with an increased risk of stratification was detected.Conclusion. The somatic status and laboratory parameters of patients with retinal vein occlusion are significantly different from the norm, which must be taken into account in the prognosis of the course of an ophthalmologic disease.

Taking into account the constant increase in patients with age-related cataracts after radial keratotomy, a careful analysis of both the optical and anatomical properties of the cornea with the examination of the posterior surface is of particular importance.Aim. To analyze the optical properties of the posterior surface of the cornea in patients after anterior radial keratotomy. Materials and methods. An examination of 24 patients (48 eyes) with age-related cataracts of varying degrees of density, myopia and the presence of a previous anterior radial keratotomy or radial-tangential keratotomy in history. The average age of patients was 59.5 years (from 47 to 68), there were 19 women and 5 men.Results. The radius of curvature of the anterior surface in patients after anterior radial keratotomy was 9.45 ± 0.91 mm on average along the meridians, which is significantly more in comparison with these indices in control patients – 7.70 ± 0.19 mm (p = 0.0001). The ratio of the radii of the posterior cornea curvature to the anterior radius on average along the meridians in patients after anterior radial keratotomy was 1.07 ± 0.70, and in control patients – 1.20 ± 0.02 (p = 0.0001). The keratometric index in patients after anterior radial keratotomy was 1.3538 ± 0.0239, and in the control group – 1.3372 ± 0.0003 (p = 0.23).Conclusion. In patients after anterior radial keratotomy, keratometry of the posterior surface of the cornea is significantly higher than in the control. The ratio of the radius of curvature of the posterior cornea to the radius of curvature of the anterior cornea varies significantly after anterior radial keratotomy, which is due to a more pronounced flattening of the posterior cornea. The standard keratometric index (1.3375) is invalid for patients after anterior radial keratotomy and must be calculated individually for each patient when deciding on the operative treatment of cataracts.

Retinal pigment abiotrophy is a hereditary disease with a primary diffuse lesion of photoreceptors and the retinal pigment epithelium, in which characteristic functional changes and a typical picture of the fundus with pigment bone bodies are noted. Retinal pigment abiotrophy is the most common disease of all dystrophies of the retina.Aim. To do a clinical genealogical analysis of the type of inheritance of pigmentary retinitis in residents of Tarbagatai region of the Republic of Buryatia.Material and methods. At the first stage of the study, a round between the residents of Tarbagatai region of the Republic of Buryatia was conducted by interviewing and questioning. At the second stage, people with suspected pigment retinitis and their blood relatives underwent a full ophthalmologic examination to confirm the diagnosis, and a thorough collection of genealogical information was carried out to determine the type of inheritance.Results. 20 patients were allocated from 12 families of 1237 interviewed people aged 15 to 76 years living in a closed community in the territory of Buryatia in the Tarbagatai region, 12 of them with a presumptive diagnosis of retinitis pigmentosa, with signs of Usher syndrome (retinitis pigmentosa + sensorineural hearing loss) – 8 people. In general, the analysis of 20 pedigrees with an established type of inheritance in 89.9 % of cases revealed an autosomal recessive type; in 10.1 % – autosomal dominant type of retinitis pigmentosa.Conclusion. A complete collection of genealogical history is the basis for the diagnosis of hereditary eye diseases.
