Correlation of stomata density to rust severity on some accessions of maize germplasm. Rust is an important disease on maize. Control of rust using resistant varieties is recommended because it is more practical and environmental friendly. This research aims to study on the correlation of stomata density to rust severity on the several maize germplasm accessions. The research was conducted in Bontobili Farm Experimental Station and ICERI Pathology Laboratory, held from March to August 2017; it used Randomized Block Design with 2 replicates. As much as 30 corn germplasm accessions and 2 varieties for comparison (Bima 10 and Anoman) were planted by spacing 20 x 70 cm. The inoculation of Puccinia sp. was allowed to occur naturally. Printing of stomata was conducted with painted the lower part of corn leaf with nail polish transparent. After drying, it was pasted with clear isolation and then it was pulled and saved on glass object. Observed parameters were rust severity on the age of 50, 60, 70 days after planting and density of stomata. Results of the experiment showed that disease severity of germplasm accession number 2, 218 and 243 were not significant with comparison (tolerant variety). Germplasm with accession number 234 was categorized tolerant to rust. The rust infection rate on all accession were categorized by mild to moderate. Density of stomata of each maize germplasm accession was significantly correlated with rust severity, the increase of stomata density could increase of rust severity at 0.73%.

Aims

Anemia is associated with poorer outcomes in patients with acute coronary syndromes (ACS), but the magnitude of this association in elderly patients remains poorly understood. No study has assessed the prognostic impact of anemia according to frailty status in this setting.

Methods

The LONGEVO-SCA registry included unselected ACS patients aged at least 80 years. A geriatric assessment was performed during hospitalization, including frailty assessment using the FRAIL scale. Anemia was defined by the WHO criteria. We evaluated the impact of anemia on 6-month mortality according to the presence of frailty.

Results

A total of 517 patients were assessed. Mean age was 84.3 years, and a total of 236 patients (45.6%) had anemia. Patients with anemia had a higher prevalence of comorbidities and higher prevalence of frailty (30.6 vs. 22.3%, P = 0.007). A total of 60 patients (12.1%) died at 6 months [40 with anemia (17.5%) and 20 without anemia (7.5%), P = 0.001]. Anemia was independently associated with mortality at 6 months in the whole cohort (hazard ratio 2.28, 95% CI 1.13–457, P = 0.021). The association of anemia and mortality was different according to frailty status, being significant in patients without frailty (hazard ratio 3.94, 95% CI 1.84–8.45, P = 0.001), but not in frail patients (hazard ratio 1.17, 95% CI 0.53–2.57, P = 0.705), (P value for interaction = 0.035).

Conclusion

A high proportion of elderly patients with ACS have anemia, leading to a worse prognosis in the whole cohort. The association between anemia and mortality was especially significant in robust patients, whereas the poorer prognosis in frail patients was not modified by the presence of anemia.

Published: October 2019

Material handling systems, as an important part of different type of manufacturing processes, face the same challenges as manufacturing industries pushed nowadays forward by innovative ideas and technologies to the next level loudly announced as industry 4.0. Development of the next generation of automated manufacturing systems involves advanced approaches to material handling systems design and their close integration with the higher levels of manufacturing and production control and management, e.g. manufacturing execution systems (MES), enterprise resource planning (ERP). In the presence of increasing demands for manufacturing process optimization, the role of supervisory level of material handling systems is much more advanced today, ensuring not only data acquisition, visualization, monitoring, supervisory control, as well as synchronization with the higher control levels (FEM, ERP), but also providing functionality for supporting maintenance and decision-making processes to reduce downtimes, operations and maintenance costs. The article deals with the integration of control and maintenance functions in the hierarchical control system of a crane. The supervisory system for supporting control and proactive maintenance is prototyped at the laboratory overhead travelling crane. The article presents the control-measurement equipment and intelligent software tools implemented in the supervisory control and data acquisition (SCADA) system to aid decision-making process in proactive maintenance. The overview of the main components of the supervisory control and proactive maintenance subsystems is provided, and their respective role in control, supervision, and proactive maintenance is explained. The crane’s supervisory control includes the stereovision-based subsystem applied to identify the crane’s transportation workspace, determine the safety and time-optimal point-to-point trajectory of a payload. The proactive maintenance module consists of the human machine interface (HMI) supporting decision-making process, intelligent tools for upcoming downtime/failure prediction, and the crane's girder inspection using the metal magnetic memory technique.

Authors: Menes Maciej , Wiśniowski Piotr
Published: October 2019

The automotive market is developing very dynamically. In recent years, we can observe activities of automotive concerns in the production of new models of electric, hybrid and hydrogen vehicles, and conventional cars are supplied with increasingly economical and low-emission engines. There are also increasingly stringent standards related to exhaust emissions from the exhaust system. From September 1, 2018, passenger cars have to comply with the Euro 6d-Temp emission standard and be homologated according to the WLTP test procedure including the WLTC driving cycle and emission measurements in road traffic conditions. The exhaust components measured during the test, such as carbon oxides, nitrogen oxides or hydrocarbons, are toxic to living organisms. However, it seems that the most important issue in the long term may be the value of carbon dioxide emissions, the excess of which poses an ecological threat to the entire planet. The production of new vehicles equipped with modern complicated combustion engines, batteries, fuel cells and electronic devices is associated with a very high emission of this greenhouse gas The authors of the following article, based on their own research, sought to estimate the ecological profitability of replacing a used passenger car meeting the Euro-4 emissions standard for a new vehicle bearing in mind the value of carbon dioxide emissions during vehicle production. The analysis was to indicate how intensive the annual operation of the vehicle should be to make it profitable to recycle and replace it with a modern car with lower emissions considering the global sum of carbon dioxide emissions.

Authors: Witek Lucjan , Lubas Monika
Published: October 2019

This article presents results of experimental investigations of the lap blind riveted joint. The main goal of the work is determination of destructive load of the blind riveted joints. The blind rivets were originally used in the aircraft structures where access to both sides of the riveted structure is impossible. Blind rivets are now commonly used in many branches of industry because of their low cost. Moreover, the riveting process is uncomplicated. There are many publications about analysis of strength of solid rivets in the research literature. However, the strength analysis of the blind rivets was rarely undertaken. There is the research gap in the analysis of both the strength and the load capacity of blind riveted joints. The influence of selected geometrical parameters of the joint on the stress distribution and the destructive force was not widely described in literature. The first part of the work presents a review of standards and publications related to stress and strength analysis of blind riveted joints. The next part of the study describes experimental investigations of joints. The examined specimens were made out of AW 2017 aluminum alloy, cut from 1 [mm] thick sheet. Investigated blind rivets were made out of aluminum alloy. The lap joint with one rivet and the single row five-rivet joint were investigated. Moreover, the different size of hole chamfer were considered. The experimental tests were performed with the use of Zwick-Roell tension machine. The main results of experimental investigations are ultimate shear load diagrams. The influence of both the hole chamfer and the number of rivets on destructive force and shear diagrams of blind riveted joints were in detail analysed. After shear tests, the fractured rivets were magnified in order to explain the failure phenomenon of blind rivets. In the future research works the obtained results will be used in strength analysis of the blind riveted joints using the finite element method.

Published: October 2019

The main idea of this article was to compare the results of new design electric brake to the older version of hydraulic brake in laboratory tests. The energy of braking should be very similar due to the same mass of the airplane. That is why the laboratory tests of both brakes were took place in the same stand. Of course, the parameters were similar but not at all. The main idea was to create the solution, which could be used in vehicle like airplane. The electric brakes could replace traditional hydraulic brake solution. The results could be interesting for every researcher who is interested in brakes. Other important idea of this article was to describe the tests of new electric brake prototype. The purpose of the tests was to check designing of electric brakes. The electric brake prototype should ensure sufficient efficiency, safety, reliability and durability during braking, which is required in certification processes and is particularly important when researching innovative solutions. It was really important to verify the design and check the parameters. Of course, there is really important to remember that in every new type of the prototype solutions there are many pros and cons, which are typical only for considered design. Nowadays every electric brake design is different because there is a lot of new concept.

Authors: Kolar Davor , Lisjak Dragutin , Pająk Michał
Published: October 2019

One of the most important subsystems of the vehicles and machines operating currently in industry and transportation are the rotating subsystems. During the operation, due to the forcing factors influence, the technical state of them is changing and the failure can occur. Fault diagnosis is maintenance task considered as an essential in such subsystems, since possibility of an early detection and diagnosis of the faulty condition can save both time and money. To do this the analysis of the subsystems vibrations is performed. The identified technical state should be considered in a context of the ability and different inability states. Therefore, the first step of the diagnostic procedure is the ability and different inability states identification.

Traditional data-driven techniques of fault diagnosis require signal processing for feature extraction, as they are unable to work with raw signal data, consequently leading to need for both expert knowledge and human work. The emergence of deep learning architectures in condition-based maintenance promises to ensure high performance fault diagnosis while lowering necessity for expert knowledge and human work. This article presents authors initial research in deep learning-based data-driven fault diagnosis of rotating subsystems. The proposed technique input raw three-axis accelerometer signal as high-definition image into deep learning layers, which automatically extract signal features, enabling high classification accuracy.

Published: October 2019

Many devices and systems, including electronic ones, are used in the operation of sea-going vessels. Fast technological development in the field of electronics, radio communications and computer science inspires the more and more new proposals for the changes of these devices and systems. The rules and scope of sea-going vessels equipment, related to ensuring their safety, are strictly regulated by the International Maritime Organization (IMO). Considering the above, several countries have submitted to the IMO-Maritime Safety Committee (MSC) a proposal to prepare a vision of a broad strategy for incorporating new technologies in a structural manner, ensuring their compatibility with already existing different navigation and communication technologies and services. The overriding goal of this strategy would be to improve the efficiency, safety and reducing the cost of the entire system, providing global coverage and applicable to all types of sea-going vessels. In response to this proposal, the MSC decided to start work on the project “Preparation of e-navigation strategy”. The article presents the general concepts and goals of the e-navigation project. Priority needs of e-navigation users were also discussed. The key elements of the project are presented too. The radio communication aspects of the e-navigation project were also considered. Finally, the e-navigation Strategy Implementation Plan (SIP) and its progress were presented.
Planning the Flight Trajectory of a Passenger Aircraft with Regards to the Aspect of Pollutants Emission
Authors: Pawlak Małgorzata
Published: October 2019

One of the ways to reduce the adverse impact of aircraft on the environment is through the determination of the trajectory of the flight on a given route that leads to reducing fuel consumption and, consequently, emission of pollutants in jet engines exhausts. Planning a flight in terms of minimizing emissions or fuel consumption is a complex task and difficult to implement due to the conditions in which the aircraft travels, but it is possible though. It is necessary to take into account the limitations resulting from the organization of the airspace and the rules therein, as well as the current weather conditions. The weather is one of the main factors determining the amount of fuel consumed, the time and cost of a particular flight on a given route. In addition to the main parameters, such as pressure and air density, it is extremely important to determine the air temperature, as well as the wind speed and direction. The temperature affects the speed of sound, based on which it is possible to determine the Mach number for a plane flying with a given true air speed (TAS). The speed and direction of wind, on the other hand, affect the speed of the aircraft relative to the ground (velocity over ground, VOG), and thus the duration of its flight. The article describes how the developed model of emission of pollutants in the exhausts of jet bypass engines can be useful for determining the trajectory of an aircraft in its cruise phase due to the criterion of pollutants emissions minimization. An exemplary analysis was carried out for selected aircraft moving along the route adopted for the research. The analysis covered various cruising altitudes and various meteorological conditions (wind speed and direction). The obtained results are illustrated graphically and discussed.

Authors: Szokało Agnieszka Aleksandra , Rychter Marcin
Published: October 2019

Digital tachographs as devices recording the work of a lorry and driver’s work are a constant factor in the work of a professional driver. It is therefore important to preserve the security of recording and storing electronic information. In this matter, cryptography also becomes an inseparable field of science. The control services set up to conduct roadside inspections do not detect all violations in the recording devices by encrypting information in information systems. One of the frequent vehicle operating parameters that can be falsified are the speed of the vehicle and its rotational speed, as well as the time and efficiency of the driver’s work. These parameters affect the amount of fuel consumption. The reduction of fuel consumption translates directly to the reduction of harmful substances emitted by the car to the environment. Variable compression engines are becoming the future of motoring in the case of internal combustion engines. It is noticeable that there are more frequent deliberate of regulations; and more violations rules concerning the proper functioning of recording devices by recording driver activity. Current methods of preventing violations are insufficient. The article points out the violations related to the actual rotational speed of the crankshaft of the internal combustion engine in relation to the vehicle speed profile, which is directly related to the fuel consumption and the emission of harmful substances. The article describes the ways to reduce fuel consumption, of which the correct driving technique is important in addition to the previously marked parameters. The factors that increase the awareness of professional drivers in the aspect of proper driving techniques are described.
Brand Love as Mediator of the Brand Experience-Satisfaction-Loyalty Relationship in a Retail Fashion Brand
Authors: Ferreira Pedro , Rodrigues Paula , Rodrigues Pedro
Published: October 2019

Framed by the consumer-brand relationship theory, this paper investigates the path from the brand-consumer behaviour interaction to the relationship durability and stability, through brand relationship quality. Specifically, it examines brand experience as an antecedent of brand love, and customer loyalty and satisfaction as outcomes in the retail setting. Based on 560 customers’ responses to a face-to-face questionnaire administered in a fashion brand retail store, research hypotheses were tested using a structural equation model. The findings suggest that brand experience influences brand love, with a higher incidence of sensory and affective dimensions. Brand love, in turn, influences customer loyalty, both directly and indirectly through customer satisfaction. This research contributes to the still understudied relation between brand experience and brand love in the retail context and to the need to understand the satisfaction-loyalty relation involving other variables as predictors. Nevertheless, results are limited to one specific retail fashion brand and generalizations should be taken carefully.

Authors: Mahdavi Mehdi , Barbosa Belem , Oliveira Zaíla , Chkoniya Valentina
Published: October 2019

Literature has highlighted the challenges of selling experience (vs. search) products online. In addition, the role of celebrity endorsers in purchase intention and attitudes towards brands has been emphasized by scholars. This article argues that celebrities provide cues on products’ sensorial characteristics that have been so far disregarded by extant literature. By choosing perfume as a complex experience product, twenty-seven participants from three countries were interviewed in order to find how endorsers could assist e-shoppers to identify fragrant characteristics in the absence of the real scent. The results of the qualitative content analysis reveal that endorsers’ personality traits and lifestyle could act as predictor of the type of scent. Scent categorization based on such traits are presented. This article provides valuable contributions to both researchers and practitioners interested in online sales of experience goods. Limitations and avenues for future search are also provided.
The “question-mark” MR anatomy of the cervico-thoracic ganglia complex: can it help to avoid mistaking it for a malignant lesion on 68Ga-PSMA-11 PET/MR?
Authors: Bialek Ewa J. , Malkowski Bogdan
Published: October 2019

Background

Detectable uptake of 68Ga-PSMA-ligands in sympathetic ganglia may potentially lead to mistaking them for malignant lesions. Our aim was to investigate the anatomy of cervico-thoracic-ganglia-complex (CTG-C) in the MR part of multimodal 68Ga-PSMA-11 PET/MR imaging, in view of PET factors hindering its proper identification.

Patients and methods

In 106 patients, 212 sites of the CTG-C were retrospectively reviewed to assess the radiotracer uptake (SUVmax), size, shape, position, symmetry of location and visual uptake intensity. Asymmetry of PSMA-ligand uptake and increased uptake were regarded as risk factors of malignancy.

Results

In 66.0% left (L) and 53.8% right (R) CTG-C we noticed configurations, resembling the shape of an exclamation-mark, a question-mark, or its part (called “typical”). Tumor-like CTG-C shapes (oval, binodular or longitudinal) were detected in 28.3% L-CTG-C and in 40.6% R-CTG-C. When visual assessment of PET suggested malignancy, the recognition of “typical” shape of underlying CTG-C on MR generated a rise in the accuracy of their proper identification (from 34.4% to 75%, χ2(1) = 70.4; p < 0.001). Recognizing the shape of the CTG-C as “typical” in MR allowed us to classify as “not-suspicious” 61.9% of all CTG-C which were treated as “suspicious” after sole PET assessment.

Conclusions

The characteristic shape of cervico-thoracic-ganglia-complex (resembling a question-mark, or its part) helps in proper recognition of CTG-C on multimodal whole-body 68Ga-PSMA-ligand PET/MR imaging, when detectable uptake might lead to considering pathology.

Objetivo: Transmitir informações a respeito das diversas formas de infecção pelo vírus HPV, correlacionando suas manifestações clínicas a partir do relato de caso de paciente com infecção plantar. Detalhamento do caso: Paciente MAF, 40 anos, acompanhada em ambulatório de Ginecologia por quadro de verrugas genitais e anais, queixa-se de calosidades nos pés de longa data, com dor à pressão plantar, de evolução há 5 anos. Ao exame físico, genitália apresentava lesão única verrucosa em região perianal e lesão verrucoide vulvar sugestivas de HPV. Nos pés, foi evidenciada a presença de múltiplas lesões hiperceratóticas, disseminadas, prevalecendo em pé esquerdo, com nodulação subcutânea à palpação. Diante da suspeita de lesões induzidas por HPV foi prescrito Thuya 6CH diariamente. No retorno, paciente havia apresentado melhora do quadro, permanecendo em acompanhamento. Considerações Finais: Observa-se vasta gama de manifestações clínicas pelo vírus HPV, pouco exploradas devido à dificuldade em encontrar na literatura imagens semelhantes às obtidas no caso para comparação. O quadro clínico inespecífico dificulta o tratamento, prolongando o ciclo de disseminação do vírus, prejudicando as pacientes.

Objetivo: Apresentar o perfil epidemiológico dos casos de violência contra crianças menores de 10 anos no Estado de Goiás, no período entre 2009 e 2014. Métodos: Trata-se de estudo descritivo-analítico, cujos dados foram obtidos por meio do preenchimento da ficha de notificação “Violência doméstica, sexual e/ou outras violências”, disponível no SINAN. Utilizou-se como amostra crianças menores de 10 anos vítimas de violência no período entre 2009 e 2014 no Estado de Goiás.  Foram calculadas as frequências de variáveis segundo as características da ocorrência em relação ao ano, faixa etária e sexo das vítimas, tipo de violência, vínculo do agressor com a vítima, e evolução do caso. Resultados: Obteve-se amostra de 3.258 casos referentes à violência contra a criança no período analisado, na qual houve prevalência da negligência/abandono na faixa etária entre 5 e 9 anos de idade e no sexo feminino, sendo os agressores, principalmente, os pais das crianças. A maioria dos casos de violência infantil evoluiu com alta hospitalar. Conclusão: Estes dados apontam a necessidade de se fortalecer intervenções no sentido de ampliar a rede de proteção social às crianças.

Objetivo: Relatar o caso clínico de frenectomia lingual em uma criança com anquiloglossia, visando sua restituição fono-motricial. Descrição do caso: Paciente do sexo masculino, melanorderma, sete anos de idade, com queixa de bullying no ambiente escolar devido à dificuldade na dicção. Ao exame clínico, observou-se o freio lingual curto e fixado ao ápice da língua, resultando na limitação da protrusão e da projeção da língua em direção ao palato duro, além do comprometimento na dicção de alguns fonemas, confirmando o diagnóstico de anquiloglossia. Como conduta terapêutica, optou-se pela intervenção cirúrgica convencional (frenectomia). No pós-operatório imediato foi observado o freio centralizado no ventre lingual, bem como a eficiência na elevação e protrusão da língua. Uma vez que o paciente continuava com comprometimento fonético, o mesmo foi encaminhado para fonoterapia. Durante o acompanhamento pôde-se constatar melhora na fonação e ausência de queixas relacionadas aos aspectos comportamentais e convívio escolar. Considerações finais: A frenectomia de um freio lingual curto, tardiamente diagnosticado, apresenta-se como uma técnica cirúrgica de fácil execução e com potencial para restabelecer as funções motriciais da língua. Além disso, a instituição de uma abordagem multiprofisional, associando intervenção cirúrgica à fonoaudiológica, contribuiu para a restituição fonética e reinserção social do paciente.
A Mechanism for Reversibly Pausing a Self-Immolation Cascade in Response to pH Changes
Authors: Roberts Derrick , Pilgrim Ben S. , Dell Tristan , Stevens Molly
Published: October 2019

We describe the first report of a self-immolation cascade that can be reversibly paused and reactivated in response to pH changes. This system employs a triazole-based self-immolative linker, which expresses a pH-sensitive intermediate during its elimination sequence. This allows the system to respond to pH cues within its local environment, thus establishing a new way to gate self-immolative release using fluctuating or transient chemical signals.
Large Scale Indium Tin Oxide (ITO) One Dimensional Gratings for Ultrafast Signal Modulation in the Visible
Authors: Scotognella Francesco
Published: October 2019

We present a photophysical study on an indium tin oxide (ITO) one dimensional grating, realized using femtosecond micromachining technology, a technology very industrially accessible. The geometries, dimensions and pitch of the various gratings analyzed are obtained by means of direct ablation in a controlled atmosphere of a homogeneous thin layer of ITO deposited on a glass substrate. The pitch has been selected in order to obtain a higher order of the photonic band gap in the visible. By means of ultrafast pump-probe spectroscopy we characterize both the plasmon and inter-band temporal dynamics. We observe a large optical non-linearity of ITO grating in the visible range, where the photonic band gap occurs, when pumped at the surface plasmon resonance in the near infrared (1500 nm). All together we show the possibility of all-optical signal modulation with heavily doped semiconductors in their transparency window with a picosecond response time through the formation of ITO grating structures.
Alchemical Hydration Free Energy Calculations Using Molecular Dynamics with Explicit Polarization and Induced Polarity Decoupling: An OTFP Approach
Authors: Kelly Braden , Smith William
Published: October 2019

We present an algorithm to calculate hydration free energies in explicit solvent that incorporates polarization of the solute molecule in conjunction with the use of a classical fixed--charge force field. The goal is to improve the accuracy over the alternative approach of developing a polarizable force field with adjustable parameters. We incorporate polarization by implementing on--the--fly periodic updating of the solute's partial charges during a standard molecular dynamics (MD) alchemical change simulation by the use of mixed QM/MM calculations. We decouple the polarizing solvent's electric field along with the normal MD solute Coulomb decoupling to calculate the free energy difference between an unpolarized solute in vacuum and a fully polarized solute in solution. This approach is in contrast to the common approach of GAFF, which calculates the difference between a solute in vacuum that is over--polarized by the use of fixed charges calculated using HF/6-31G*, and correspondingly under--polarized by the same partial charge set in the solution phase. We apply our methodology to a test set of 31 molecules, ranging from small polar to large drug--like molecules. We find that results using our method with Minimum Basis Iterative Stockholder (MBIS) charges and using RESP charges with B3LYP/cc-pVTZ are superior to results calculated using the current ``gold standard" AM1--BCC method. We show results using MBIS partial charges using B3LYP/cc-pVTZ and MP2/cc-pVTZ, RESP partial charges using B3LYP/cc-pVTZ and HF/6-31G*, and AM1-BCC partial charges. Our method using MBIS in conjunction with MP2/cc-pVTZ yields an AAD that is 2.91 kJ$\cdot$mol$^{-1}$ (0.70 kcal$\cdot$mol$^{-1}$) lower than that of AM1--BCC for our test set. AM1-BCC was within experimental uncertainty on 13 \% of the data, while our method using MP2 was within experimental uncertainty on 43 \% of the data. We conjecture that results can be further improved by using Lennard--Jones and torsional parameters that are fitted to the MBIS charge method and that using RESP with our method can be improved by using a higher level of theory than B3LYP, for instance MP2 or $\omega$B97X-D.

Spacing between adjacent teeth is known as Diastema, many of the patients seek closure of diastema for aesthetic reasons. Diastema less than 2 mm close spontaneously ,if they do not do so then they should not be straightaway corrected rather a thorough clinical and radiographic examination should done to  determine the underlying cause and to rule out anomalies, such as the presence of any supernumerary  tooth or odontoma’s which should be ruled out before going on for orthodontic therapy. The purpose of this article is to present and discuss the case of a 9-year old child with the chief complaint of spacing between the maxillary right permanent central incisor and right permanent lateral incisor. Radioopaque calcified masses were seen in the radiograph and was diagnosed with compound odontome followed by the surgical removal of the calcified masses.
