The Characteristics of Partial Discharge on Corona Defect in GIS based on Multi-Detection method

Gas insulated switchgear (GIS) is the most important equipment in the power grid. The partial discharge (PD) is the premonitory detection method for the insulation failure. The UHF detection method and acoustic detection method is the most used in filed. UHF method has excellent anti- interference performance and acoustic method has excellent defect location ability. Metal tip defect will appear on GIS for manufacturing and other reasons. The metal tip will lead to corona discharge under operating voltage. It is necessary to study the characteristics of corona discharge for fault detection and diagnosis. The experimental system is set up and the corona discharge characteristics on conductor and ground in actual GIS model are studied using above two methods. The comparing of the two methods is studied in this paper. Streszczenie. Wyladowanie niezupelne moze byc metodą detekcji zlej izolacji w przelącznikach gazowych GIS.

Applications of correlation and regression analysis in assessing lentic water quality: a case study at Brahmsarovar Kurukshetra, India

The present study was conducted to determine the levels of water quality indicators and to study statistical interrelationships amongst them. An attempt has also been made to establish regression equations to provide a prediction of water quality prior to detailed investigation. The studies were conducted at the “Brahmsarovar” an important religious water tank at Kurukshetra in India, where mass bathing (about 3–4 lakh pilgrims) on new moon day is an important activity. Water samples under investigation were analysed for physico-chemical (temperature, pH, free Carbon dioxide, Dissolved oxygen, Biochemical oxygen demand, Total alkalinity, Hardness, Calcium, Magnesium, Phosphate, Ammonia and biological characteristics (total plankton, total phytoplankton, total zooplankton, Species diversity indices of phytoplankton and zooplanktons). A significant (p< 0.05) positive correlation was observed between dissolved oxygen with total plankon and phytoplankton population and negative correlation was found between Dissolved oxygen and free carbon dioxide, biochemical oxygen demand and with ortho-phosphate and so on in other parameters. Multiple regression analysis showed that of among all the factors studied dissolved, biochemical oxygen demand and ortho-phosphate appears to be an important to predict the water quality. The validity of regression equation obtained was tested with the data and the relationships were found significant to predict water quality when one variable is known for similar habitats.
Exploring the role of sugarcane in small-scale farmers’ livelihoods in the Noodsberg Area, Kwazulu-Natal, South Africa

Participatory, mixed-methods research was conducted to study the role of sugarcane in small-scale sugarcane farmers’ livelihoods in the Noodsberg area, KwaZulu-Natal. Thirty-five farmers were visited at their homes and data was collected through semi-structured interviews, participatory sketch mapping, matrix scoring activities and informal field-based discussions. Results indicated that sugarcane was a key livelihood resource providing employment and income, and it generated more income than any other single agricultural enterprise. It was considered the most important crop in most households, even though it was grown within a diverse agricultural system including maize, beans, taro (amadumbe) and potatoes. Considering the important role of sugarcane as a cash crop in farmers’ livelihoods, further development of land to sugarcane in the Noodsberg area will continue to reduce poverty and improve the livelihoods of farmers. Keywords : farming systems, food security, poverty, rural development, small-scale growers, sugarcane.

Chlorophyll fluorescence emission and its relation to skin color and firmness during ripening of guava fruit

Introduction . Chlorophyll fluorescence (chl-fluorescence) has been used in postharvest studies as a non-destructive technique for evaluating fruit ripening. Since there are no available studies using chl-fluorescence in guava fruit, the aim of this work was to verify the relations between chl-fluorescence parameters and fruit quality attributes, such as skin color and fruit firmness, and to measure the chl-fluorescence during ripening of guava fruit. Materials and methods . Firstly, maximal (Fm ), minimal (Fo ), variable (Fv ), and variable to maximal [Fv /Fm ] fluorescence yields, skin color (Ho) and fruit firmness were evaluated in guava fruit harvested at three ripeness stages: dark-green (I), light-green (II) and yellowish-green (III). Secondly, changes in the above chl-fluorescence parameters and Ho were measured during 7 days of ripening. Relations between the evaluated parameters were also studied. Results and discussion . The three ripeness stages were well segregated using the Ho, Fm and fruit firmness parameters. Fo was insensible to early changes in fruit ripening, maintaining relatively stable values until fruit firmness of 20 N. When considering changes in chl-fluorescence and Ho during ripening, there were no significant differences between guava fruit harvested at stages II or III. The [Fv /Fm ] value decline was only evident on the fifth day of ripening, whereas Fv , Fm and Ho began to decrease on the first day. Regardless of [Fv /Fm ], the relations between chl-fluorescence parameters and Ho tended to increase from ripeness stages I to III, with Fm having the highest correlation with Ho. The results show that chl-fluorescence can be used to evaluate the ripening and senescence of guava fruit, with Fm being a good ripening indicator.
Maximizing pine tip moth control: Timing is everything

INTRODUCTION The impact of the Nantucket pine tip moth, Rhyacionia frustrana (Comstock), has become of increasing concern as standard silvicultural practices have intensified in southern pine production. The associated silvicultural manipulations of site preparation, herbaceous weed control, release, bedding and fertilization have shortened rotation lengths and increased volume yields (Nowak and Berisford 2000), but have often elevated tip moth infestation levels (Nowak and Berisford 2000, Ross and others 1990). As a result, insecticide applications are now being considered as part of silvicultural prescriptions for intensively-managed pine plantations.
Efficacy of tablet-based applications for mental training in preserving cognitive abilities of older adults

Background and aims: Nonpathological, age-related cognitive decline is among the most feared consequences of aging. Evidence suggests that the continued use of mental abilities can slow down cognitive decline. We developed two tablet-based applications for the mental training (ElasticaMente) and social interaction/entertainment (iNonni) of older adults. The aim of this study was to evaluate their effect on cognitive performance.Materials and methods: This was an exploratory study of 8 months duration. Sixty healthy residents of a senior community center aged ≥60 years were recruited and divided into three groups: participants in Groups 1 and 2 received a tablet with ElasticaMente and iNonni (Group 1, n = 20) or with iNonni only (Group 2, n = 20); participants in Group 3 (n = 20) did not receive any tablet. Participants in Groups 1 and 2 were instructed to use the applications three times a week (each session ~45 minutes). Cognitive performance was assessed at baseline (T0) and after 8 months (T1) using a battery of six validated tests.Results: In Group 1, cognitive test scores remained consistently stable from T0 to T1, suggesting maintenance of cognitive abilities. In contrast, in Groups 2 and 3, scores worsened from T0 to T1 across all tests. Comparison of the changes from T0 to T1 revealed statistical significance for Group 1 versus Group 3, but not for Group 1 versus Group 2 and Group 2 versus Group 3.Conclusion: The 8 months use of the applications ElasticaMente and iNonni was associated with a significant benefit in terms of preserved cognitive performance compared with no tablet-based activity. The potential contribution of ElasticaMente to the attenuation of cognitive decline should be further investigated.
Intrusion Inspector and Detector in Local Area Network Using SNMP and MMC Techniques [IIDLAN]

Intrusion Detection System (IDS) is one of the tools that help detecting any attack or any intrusion in a network. During the monitoring of a LAN, the intrusion entered to the network can be decreased. However, we need some tools that help us finding the intrusion in the network. This paper presents our approach IIDLAN which is a compound techniques that improve the protection of data such as Microsoft Management Console (MMC) as a techniques of event viewer to monitor any intrusion on the workstation, and the simple network management protocol (SNMP) that assist managing the performance, bandwidth, and plane of the network. Our approach IIDLAN aims to raise the protection of a LAN that is conducted with misuse or anomaly intrusion. Using SNMP alone cannot manage every event on the workstation and using MMC alone cannot manage the activities of LANs individually and with each other. The integration of SNMP and MMC within the approach IIDLAN makes the security of the network higher due to the existence of more two monitoring tools. Results show the performance of the network in terms of data transmission rate, time latency, utilization using SNMP technology, and many aspects of monitoring the networks components and devices using MMC tool.
A Study on Classification of Facility Elements for Supporting Project Definition of Urban Renewal Mega Project Using Morphological Box Method

Urban renewal mega projects consisting of a number of individual projects should be approached from the program level. BIM (Building Information Modeling) can feed information from product models of individual facilities to program management. In order to this end, the projects that are parts of a program have broken down with consistent and integrated manner towards program management. This breakdown including project relations is expressed as PBS (Project Breakdown Structure). Facility breakdown structure that the usage of facility and spatial hierarchy is contemplated was built with morphological box method. Morphological box methods, means to discover and devise morphologies of unbiased, useful and new idea, has extended widely its range of application from space engineering to civil engineering design and architectural design. Data process modeling was designed which is applicable both to geographic information reflecting spatial hierarchy and applicable to BIM reflecting facility breakdown structure. Information on facilities classified according to it is used for economic feasibility analysis on pre-design phase, management in construction phase and facility management in maintenance phase as required. This paper presents a method to define the spatial hierarchy of facilities to support managing urban renewal mega projects at the program level. In order to this end, the project should be classified with a consistent breakdown facility.
Design and Characterization for Regenerative Shock Absorbers

The trend of reducing the emissions in automotive sector leads to the development of electrification of vehicle powertrain and chassis. Those vehicles equipped with regenerative shock absorbers can transfer the vibrational energy coming through the road irregularities into electricity which can be further used for other purpose, i.e. to charge the battery. To realize the regeneration target, the developed device should be able to vary their damping behaviors while converting part of the dissipated power into electricity. Therefore, an electric machine together with a suitable transmission system need to be integrated to the vehicle. Several types of solutions have been investigated during the last two decades. In the present thesis, one prototype of regenerative damper with controllable damping and energy harvesting features is developed. The regenerative shock absorber employs the electro-hydrostatic actuation principle, uses a hydraulic actuator directly interfaced with a motor-pump group by means of hydraulic circuit to convert the linear motion of the piston into rotation. To maximize the energy regeneration as well as to guarantee the damping features, the hydraulic, mechanical and electric subsystems must be integrated and optimized as an entire system. The thesis establishes a system-level approach during the design phase while complying with important constraints such as envelop volume and supply voltage limitation. Different aspects that will affect the final conversion efficiency are analyzed individually, a prototype is also produced and fully characterized with experimental tests. Furthermore, this approach can be extended to any motor-pump unit for hydraulic regenerative dampers. The significance of the present work can be seen also from its integration with the electric powertrain. Since the shock absorber is electrical, it can easily transfer the power to the vehicle battery which is also electrical, in this case, a single system can be used to handle the energy. Another important aspect is about the autonomous driving technology, since systems and devices nowadays are getting towards having more controlled damping properties to enhance the driving comfort experience.

Hard martial arts for cognitive function across the lifespan: a systematic review

Background and Study Aim: Martial arts are offensive and defensive combat systems, characterised by coordinated and cognitively complex movements. Martial arts are typically classified as “hard” and “soft” styles. Hard styles focus on quick and forceful movements involving striking, kicking, blocking, grabbling, and takedown (e.g., karate, taekwondo, kung fu and judo). The aim of this review is in the existing scientific literature knowledge about pertaining to the effects of martial arts on cognitive function across the lifespan. Material and Methods: Both electronic and manual searches of the English-language articles published were conducted without limiting year of publication. The rigorous critical appraisal was independently performed, resulting in the inclusion of 18 studies. Results: Study results from the existing scientific literature indicate that martial arts (karate, taekwondo, kung fu, and judo) can improve some selected aspects of cognitive function and neurotrophic factors (serum BDNF and IGF-1) associated with brain health. Specifically, martial arts could be promising approaches to potentially stimulate the development of cognitive function in children and adolescent, and decelerate cognitive decline in middle-aged and older adults. Conclusions: Hard martial arts may be beneficial for improving some selected aspects of cognitive function across the lifespan. Because only a few studies used randomised controlled trials, a definitive conclusion regarding the beneficial effects of martial arts on cognitive functions is still difficult to be made at this stage. To better understand the effects of martial arts for cognitive function across the lifespan, future research should involve larger sample sizes, well-controlled designs, standardised assessments and long-term follow-ups, measures of health status, exercise intensity, leisure time activities, and session attendance rates.
Mineral Composition of Leaves and Tubers of Potato (Solanum tuberosum L.) Plants Cultivated in the Eastern Highlands of Ethiopia

The problem of low yield and quality of potato in Ethiopia is attributable to nutrient deficiencies. Therefore, a survey was conducted to elucidate the problem through plant tissue analyses. Mature and fully expanded potato leaves and tubers were sampled randomly from purposively selected smallholder potato farms across seven villages in the eastern highlands of the country. The leaves were analysed for both macro- and micronutrients and the tubers were analysed for selected macronutrients. The data were subjected to analysis of variance, and explored with descriptive statistics. Ranges of leaf and tuber mineral concentrations were compared with deficiency, sufficiency, and excess ranges published for the crop. Leaf and tuber concentrations of the selected macronutrients were subjected to a correlation analysis. The results revealed that leaves sampled from four out of seven villages were deficient in nitrogen and phosphorus. Leaves from all villages were sufficient in all other macronutrients. Similarly, tubers sampled from five out of seven villages and those from three out of seven villages were deficient in nitrogen and phosphorus, respectively. Tubers from all villages were sufficient in potassium, calcium, and magnesium. Leaf micronutrient deficiencies were detected only for iron and manganese in two villages. Leaf and tuber concentrations of most mineral nutrients varied significantly across the villages, and some correlated positively. In conclusion, potato plants in the surveyed farms suffered mainly from nitrogen and phosphorus deficiencies, followed by deficiencies of iron and manganese. Keywords : Deficiency; Leaves; Nutrient Concentration; Sufficiency; Tubers

We thank the Reviewer #1 for the detailed revision and the many constructive comments. We considered them carefully and we are confident the Reviewer #1 will be satisfied by the next version of the manuscript. On the other hand, we had to make a major change to the manuscript. Reviewer #2 had serious concerns on GPP estimations for the pine stand. Although we re-analyzed the data and evaluated possible amendments, we realized that due to the large spatial heterogeneity there was no standard way to produce reliable GPP estimates from the EC system for the pine stand.

Does Geographic Factors Determine Local Economic Development

The purpose of this paper is to analyze the influence of geographic characteristics on the local economic development. There are two important reasons related to that objective. First, study on this topic in the case of Indonesia is rather limited, especially in the field of local economic development of the country. Second, geographically, Indonesia is a heterogeneous country and its consequence is development policy should also consider the geographic characteristics of the country. The study estimates impact of some geographic variables on the Gross Domestic Regional Product (GDRP) per capita and GDRP density as indicators of local economic development with data of the districts in the Central Java province uses regression models. Geographic variables used in the model are distance to economic centres, location of districts, and a measure of clustering of economic activity. Other socio-economic variable is also used in the model, such as literacy rate which is one of the components of human development index (HDI). This study found that in general geography influences local economic performance; however, geography is not the only determinant of economic performance. It also suggests that study on geographic inequality not only apply “per capita approach” but also “density approach” to get a more comprehensive picture of the impact of geography on economic development.
