People want energy to satisfy their each day needs. However, maximum of those energy customers are now no longer aware that using an electric powered load is too large, which regularly reasons disturbances. In coping with overload disturbances withinside the family sector, MCB is used as a protection tool. The running precept of the MCB continues to be the usage of magnetic, so it's far less effective. When disconnecting the cutting-edge because of overload, the MCB will experience a touch overdue, which could reason sparks and a hearthplace withinside the family. Therefore, on this look at a cutting-edge sensor protection circuit is designed to update the MCB. This circuit can show the cutting-edge cost at the LCD and restriction the overcurrent to a restriction of three amperes. The overload safety machine constructed from the ACS712ELC-5A cutting-edge sensor can come across currents among 0A and 5A. So, to reduce off the cutting-edge, a 12V relay is used. When trying out a ready-made machine, this protection tool can study currents withinside the variety 0A to 3A, with median studying mistakes of 0.65%. If the burden is better than 3A, the machine also can reduce the cutting-edge.

Abstract A Rogowski coil based sensor for current measurement in a cryogenic environment and results of its application for paralleled high temperature superconducting (HTS) coil current sharing are presented. The current sensor consists of a Rogowski coil and an integrator, where the coil output voltage is proportional to the derivative of primary current and the integrator transfers the differentiation to normal state. The Rogowski coil has promising applicability at cryogenic circumstance because its body is made of low temperature materials. The integrator ensures a large bandwidth with feasible magnitude, which is vital for dynamic current measurement during the quench of the HTS coil. The proposed current sensor is used for current sharing measurement of two paralleled Bi2223 HTS coils, and the experimental results show that the measurement precision is better than 0.5%.

In this paper, a method is proposed for determining a basic profile of a cc-type single-screw compressor including the gate rotor and the screw rotor. The cc-type has a cylindrical screw and two cylindrical gate rotors. Based on this method, a mathematical model of the meshing principles of a cc-type screw rotor meshed with a gate rotor, that has either straight edge teeth or conical teeth, is presented. The inverse envelope concept is used to determine the cutting-edge curve of a gate rotor. Based on this concept, the required cutter for machining a cc-type screw rotor can be obtained by the envelope of a one-parameter family. The obtained screw rotor is an envelope to the family of the gate rotor's surfaces. The obtained envelope becomes the generating surface. The inverse envelope can be used to obtain the envelope to the family of generating surfaces. Then the profile of a gate rotor cutting-edge curve can be easily obtained. The surface analysis including contact lines is shown for the design and manufacture of a screw compressor. As an example, the cc-type single-screw compressor with a compressor ratio of 11:6 was determined with the aid of the proposed mathematical model. Using rapid prototyping (RP) and manufacturing technology, a cc-type single-screw rotor with a gate rotor was designed. The RP primitives provide an actual full-size physical model that can be analysed and used for further development. Results from these mathematical models should have applications in the design of cc-type single-screw compressors.

RESUMOObjetivo: Conhecer como as famílias de crianças surdas usuárias de Implante Coclear percebem o desenvolvimento de linguagem da criança e relacionar esses dados com o tempo de uso diário e a quebra do dispositivo. Métodos: Trata-se de pesquisa de caráter exploratório com abordagem quantitativa. Realizou-se um levantamento do número de crianças implantadas em um serviço de saúde auditiva de um hospital escola, entre 2013 e 2015 e para aqueles que aceitaram participar da pesquisa, aplicou-se entrevista e a Escala de Aquisições Iniciais de Linguagem (ELM) com um dos membros da família, sendo esta áudio-gravada, via contato telefônico. Resultados: Das 66 crianças implantadas neste período, 52 participaram da pesquisa, sendo que destas 51 utilizavam o dispositivo. Verificou-se que a maioria (90,4%) frequentava terapia fonoaudiológica e as famílias relataram que estimulam o desenvolvimento da linguagem das crianças em casa. Aquelas classificadas com desenvolvimento de linguagem típico receberam o implante coclear precocemente, utilizavam o implante coclear o dia todo e nunca tiveram o equipamento quebrado. Quanto à Escala ELM, foi encontrado que existem mais casos de desenvolvimento típico para linguagem receptiva do que para a expressiva. Conclusão: Houve relação entre o uso do dispositivo e o desenvolvimento típico e a quebra do equipamento com desenvolvimento atípico de linguagem. Os familiares referiram que a compreensão de linguagem encontra-se mais adequada do que a produção da fala.

Methods: The research was observational, exploratory, with quantitative approach. A survey of the number of patients implanted in a Hearing Health Service of a public hospital was done, between 2013 and 2015 and it was applied an interview and the Early language Milestone Scale with one of the family members, audio-recorded, through telephone contact. Results: Out of the 66 implanted children, 52 families participated in the research and 51 used the device. It was verified that most of the children (90.04%) were in speech and language therapy and the families stimulated language development at home. The children with typical language development got the IC early in life, used the device all day and the implant never broke. In the ELM scale, it was found that there are more cases of typical development for receptive language than for expressive. Conclusion: There was a relationship between the use of the device and typical language development and the problems in the device with atypical language development. The families see that the children show receptive language development better than the expressive language.Key words: Cochlear Implantation; Deafness; Hearing Loss; Language; Child Development

Aquilaria malaccensis is an agarwood-producing species in the family Thymeleaeceae. Agarwood is a fragrant resin used in the manufacture of incense sticks, and in pharmaceutical, perfumery and cosmetic industries. In addition to the resin, hydrosol and residual water by-products from agarwood woodchip distillation are also utilized. Hydrosol contains water-soluble fragrant chemicals used as a tonic drink, in cooking and cosmetics while the residual water is used in spas and aromatic bath treatments. The present study was conducted to identify and compare compounds present in hydrosol and residual water by-products of diploid and polyploid A. malaccensis. Four different four-month-old A. malaccensis plants were compared: soil-grown diploid seedlings (DS), in vitro-grown seedlings (DV), tissue culture-derived plantlets (DC) and artificially induced tetraploid plantlets (TC). Hydrosol water from TC leaf and root samples were found to contain higher amounts of compounds compared with other samples. The TC leaf samples were qualitatively better as key compounds of agarwood such as α- and γ-eudesmol were detected. TC stem samples also contained higher amounts of key compounds compared with other samples, while the overall amount of compounds was highest in DS stem samples. The residual water of TC stem and root samples contained key compounds not detected in other samples, while DS residual water samples contained the highest total amount of compounds. Aquilaria malaccensis tetraploids performed better than their diploid counterparts in production of compounds, and thus may be a better planting material choice for commercial plantations.

Social order and peaceful co-existence are some of the primary goals in every human society. Central to maintenance of law and order in traditional Yoruba societies is the family. Culturally among the Yoruba people, women are socialized differently from men. This paper, rather than focus on the oppression of women in Yoruba cultural setting, examines the series of significant contributions of women to the maintenance of social order and ethical well-being of families. The feminine gender is not always synonymous with oppression and domination rather family well-being is mediated by the principle of complementarily between males and females. As a result, women have privileged relationship with their children better than men. Women are the pedagogues to lead their children, and this requires them to live a life worthy of emulation. The paper avers that the argument is not that men are totally left out of the moral upbringing of their children; most times they provide supportive roles. But the fact that women spend more time with the children calls for examination of their roles in the moral standing of children in Yoruba family system. Given the central role of women in the home and society, social order can be attained where women are committed to the moral upbringing of their children, rather than being marginalized in any aspect of the society.

The objective of this paper is to build a safety system which is integrated with the smart helmet and intelligent bike to reduce the probability of two-wheeler accidents and drunk and drive cases. The pressure sensor and the accelerometer sensor checks if the person is wearing the helmet or not. Alcohol sensors detects the alcoholic content in the rider’s breath. If the rider is not wearing the helmet or there is alcohol content found in rider’s breath, the bike remains off. The bike will not start until the rider wears the helmet and there is no alcoholic content present stating that rider did not consume alcohol. When the rider crashes, helmet hits the ground and sensors detect the motion and tilts of helmet and reports the occurrence of an accident and sends information of the location of accident to the family members of the rider and the emergency contact numbers.

This study represents a system of experiments and data accompanied by scientifi c and methodological interpretations, of attachment patterns. Secure attachment is considered by many authors to be a source of parental competence. These quintessences express both, the conception of parental education and their attitude towards the typical child or the child with disabilities. Studies show that some parents adapt better than others to the child’s particularities. The family, specifi cally, off ers the child the climate of emotional security and is the fi rst social group in which the child practices social behaviors and discovers himself.
