Abstract:

Brain lower grade glioma (LGG) is a common type of glioma. The current treatment methods still have some limitations, and some LGG patients will inevitably continue to deteriorate after treatment. We found the value of lysosomal associated membrane proteins (LAMPs) in the diagnosis and prognosis of LGG, which helps to enhance the clinical understanding of LGG treatment and improved prognosis. We assess the role of LAMPs in LGG, via the publicly available TCGA database. We explored expression levels of LAMPs in LGG using GEPIA2, cBioPortal, and UALCAN databases. The correction of LAMPs expression levels with immune cell infiltration in LGG patient was assessed by TIMER database. The Lysosomal associated membrane protein 1 (LAMP1)/2/4 mRNA levels were significantly higher in LGG patients than in healthy controls. Morover, high mRNA expressions of LAMP1/2/Lysosomal associated membrane protein 3 were associated with poor overall survival. We found that the immune invasion of LGG was almost significantly correlated with the expression of LAMPs. The results suggested that mRNA expressions of LAMP1 and LAMP4 were significantly associated with histological subtypes in LGG patients. lysosomal associated membrane protein 2 and LAMP5 were significantly down-regulated expression in samples of TP53 mutant in LGG compared to TP53 wild type. In addition, Lysosomal associated membrane protein 3 and LAMP4 were significantly overexpressed in samples of TP53 mutant in LGG Enrichment analysis applied to each component indicated that biological function was primarily associated with series of pathways in synapse and immunity.

Abstract:

Lampu Gentur merupakan lampu asli kota Cianjur. Keberadaan lampu ini sudah ada sejak 1920. Seiring dengan berkembangnya jaman, bahan pembuatan lampu Gentur digantikan dengan bahan kuningan dan juga kaca yang berwarna-warni. Namun sayangnya hal tersebut tidak diiringi dengan perkembangan desainnya. Desain lampu Gentur dari dulu hingga sekarang hanya mencontoh dari lampu-lampu lain, khususnya bentuk klasik Kolonial Belanda dan Timur Tengah. Hal ini sangat disayangkan karena membuat Lampu Gentur tidak memiliki ciri khasnya tersendiri padahal para pengrajin sangat terampil membuat lampu yang berbahan baku kuningan dan kaca ini. Dilatarbelakangi kurangnya identitas desain lampu gentur, maka paper ini mencoba menghubungkan teori semiotic dalam perancangan ini menghubungkan simbol budaya Cianjur yaitu ayam pelung dan lampu gentur. Tujuan dari penulisan paper ini adalah pencarian identitas desain lampu gentur dengan pendekatan teori semiotic, diharapkan paper ini dapat memberikan model bagi desainer, bagaimana mendesain produk yang beridentitas budaya lokal. Metode yang digunakan adalah pendekatan teori semiotic pada proses desain. Hasil yang didapatkan adalah desain lampu gentur baru dengan mengambil ayam pelung sebagai inspirasi.Gentur lamps are one of Cianjur’s finest crafts. These lamps have been produced since 1920. At first, Gentur lamps were made based on the initiative of the Santri (Islamic priest) to make lighting by imitating Dutch people’s lamps that they used in their houses. Unfortunately, from the 1920s until now, Gentur Lamp designs haven’t developed much in terms of identity, always imitating what’s available in the market. On the other hand, Cianjur people are very skillfull in the craft skill of lamp making. From this lack of design identity background, this paper tries to elucidate the design identity of Gentur lamps by using semiotic theory, by connecting the cultural symbology of Cianjur, pelung chicken with gentur lamps. The purpose of this paper is to probe into design identity in Gentur lamp production by way of semiotics theoretical approach. In doing so, this paper postulates a cultural product design model that is meant to provide designers valuable reference material for designing successfully in a cross-cultural product modality. The final result being the new gentur lamp design with Pelung chicken as design inspiration.

ABSTRACT: It is necessary to periodically maintain lighting equipment in accordance with international standards. Contamination of lamps caused by long-term use of lighting equipment will result in loss of Luminous Flux and optical losses. The decrease in lighting performance poses a visual difficulty for drivers and causes accidents. In this study, the total Maintenance Factor is numerically examined by considering the losses of diffuser and lens for LED lamps used in tunnel lighting. The variation of luminaries performance with years considering Maintenance Factors as regards environmental conditions and features of the luminaries is evaluated to demonstrate the importance of tunnel lighting maintenance. Moreover, to show the importance of LED lamps Maintenance Factor, the variation of illumination levels of LED lamps is analysed under different Maintenance Factors. It is observed that enhancing Maintenance Factor would contribute to energy efficiency. ABSTRAK: Penjagaan peralatan cahaya secara berkala mengikut piawai kebangsaan adalah amat penting.

Abstract:

<p>Teknik penangkapan ikan dengan alat tangkap bagan di Indonesia khususnya di Kabupaten Barru umumnya masih menggunakan lampu merkuri yang mana membutuhkan energi listrik yang cukup besar. Salah satu alternatif untuk mengurangi penggunaan energi listrik yang besar ini dapat digunakan jenis lampu hemat energi seperti lampu Light Emitting Diode (LED). Tujuan dari penelitian ini adalah untuk mengetahui perbedaan jenis ikan yang dominan tertangkap, komposisi jenis, dan berat ikan tertangkap antara bagan yang menggunakan lampu merkuri dengan lampu LED. Penelitian dilakukan di perairan Kabupaten Barru-Selat Makassar, Sulawesi Selatan. Lokasi pengamatan terletak pada posisi 4°22’48,7"-4°33’47,8"LS sampai dengan 119°25’05,0"-119°33’42,7"BT. Pengamatan lapang/uji coba penangkapan dilakukan pada periode Oktober-Nopember 2012 dan April-Mei 2013 (sebanyak 50 Trip penangkapan). Hasil penelitian menunjukkan bahwa komposisi hasil tangkapan bagan yang menggunakan lampu merkuri dan lampu LED didominasi oleh ikan teri hitam, teri putih, kembung lelaki, tembang, cumi-cumi, dan peperek, masing-masing sebanyak 90% dan 83%. Dengan komposisi jenis hasil tangkapan yang demikian ini menunjukkan bahwa lampu LED dapat digunakan sebagai alat bantu penangkapan ikan karena mampu memikat jenis ikan target dan cenderung hasil tangkapannya sama dengan menggunakan lampu merkuri yang digunakan nelayan bagan. Terdapat perbedaan berat hasil tangkapan bagan yang menggunakan lampu merkuri dari pada yang menggunakan lampu LED, namun dari nilai hasil tangkapan tampak tidak berbeda. Berat jenis hasil tangkapan yang dominan tertangkap dengan lampu LED sebanyak17,49 kg/watt sedangkan lampu merkuri sebanyak 4,89 kg/watt. Hasil ini menunjukkan bahwa bagan dengan lampu LED mendapatkan tangkapan lebih banyak dibandingkan dengan bagan lampu merkuri.</p><p><br /><em>Fishing techniques with lift-net fishing gear in Indonesia especially in Barru Regency still usemercury lamp which require considerable electrical energy.

The composition of the catch between mercury lamps and LED lamps was dominated by black anchovy, white anchovy, indian mackerel, sardines, squid and golden ponyfish, respectively 90% and 83%. These results indicate that the LED lights can be used as fishing tools because it is able to attract the target fish species and tend to catch higher than mercury lamps that commonly used. The difference in weight of the catch by using a mercury lamp was statistically better than the LED lights, but the value of the catch of the two types of lamps are not statistically different. Catches based upon the weight per electrical power used to indicate that the LED lights (17.49 kg / watt) is better than themercury lamp (4.89 kg / watt).</em></p>

Abstract:

Proper management and treatment of end-of-life fluorescent lamps with a toxic metal of mercury has attracted critical concern in the solid waste community. In this study, material flow analysis (MFA) and substance flow of mercury were performed on the lamps by life cycle in South Korea. It was found that, in 2020, approximately 2957 tons (or 27.9 million units) of end-of-life fluorescent lamps from households were collected and recycled by the recycling facilities in South Korea. Approximately 278 kg of mercury was recovered from the lamps and treated at the hazardous incineration facilities. Based on the results of dynamic flow analysis, the amount of fluorescent lamps to be retried is expected to continually decrease to be about 14.2 million units, which is estimated to be 23 kg of mercury. However, continued collection efforts on end-of-life fluorescent lamps owing to increasing demands for light-emitting diode lamps should be made from the perspectives of proper treatment of mercury as well as resource recovery. More detailed studies on other mercury-containing lamps (e.g., metal halogen lamps, high-pressure mercury lamps, and high-pressure sodium lamps) are warranted to determine mercury flows in waste streams for proper collection and treatment upon disposal.

Abstract:

Currently, three types of lamps are used to illuminate livestock premises, which diff er in the principle of operation: incandescent lamps, fl uorescent and LED. For more than fi fty years, fl uorescent lamps have been produced, which have much better light and energy characteristics, but such shortcomings as a complex switching scheme, noise, fl icker limit the use of these lamps in production facilities. An integral part of the microclimate of rabbit-breeding premises is the illumination, the corresponding values of the parameters of which can be achieved using various sources of artificial lighting. A comparative analysis of experimental data on the use of incandescent lamps and compact fl uorescent lamps for lighting livestock buildings has been carried out. Comparison of lighting costs confirms the cost-eff ectiveness of compact fl uorescent lamps. The total cost of lighting is reduced by almost 2 times, but the cost of lighting compact fl uorescent lamps is about 50 % of annual costs. While with incandescent lamps the maintenance costs do not exceed 6 %. The use of compact fl uorescent lamps for lighting livestock premises is an effective measure for energy saving. Compact fl uorescent lamps can reduce power consumption by about three times, but not fi ve times, as manufacturers say. The widespread implementation of compact fl uorescent lamps is constrained by the unreasonably high price–quality ratio of these products. This leads to the need for large fi nancial costs for the purchase of compact fl uorescent lamps and increase their payback period.

Abstract:

Electrical energy is a necessity from time to time and energy has an important role for technological development. Technology that continues to develop is the development of lamps for lighting many different types of lamps. In this study, two different types of lamps were tested, namely flourecent lamps of the CFL type (compact flourecent lamp) and LED lamps (light emitting diode) which aims to determine the effect of changes in voltage on the intensity of the light produced. Change the voltage using a slide AC voltage regulator with a voltage rage from 60 volt to 220 volt. The method used is the zonal cavity method where the room to be used is divided into three areas, namely the ceiling area, the space are, and the floor area. The CFL lamp used is a 20 watt spiral lamp witch has a lumen of 1300lm and a 20 watt LED lamp which has a lumen of 2000 lm. These lamps are a necessity so that research on the analysis of voltage changes on light intensity in CFL lamps and LED lamps can be achieved.

Abstract:

With the increasing awareness of energy conservation and environmental protection, high energy-consuming incandescent lamps have been largely withdrawn from the stage of mainland China’s lighting industry because the main raw material for electricity production-coal-produces mercury pollution when burned and energy-saving fluorescent lamps have made considerable progress. However, fluorescent lamps emit mercury, which still causes environmental pollution. In this work, the existing problems in the development of fluorescent lamps, and in the collection and treatment of spent fluorescent lamps were analyzed. The contributions of various external factors to the above problems were evaluated based on fuzzy theory. Finally, solutions to control the pollution of mercury from fluorescent lamps and spent fluorescent lamps were proposed. Results show that the biggest problem that causes mercury pollution is the first among three factors: energy conservation and mercury emission from fluorescent lamps and spent fluorescent lamps, spent fluorescent lamp collection and spent fluorescent lamp treatment. The best way to solve these problems is by developing an energy-saving and environment-friendly light emitting diode (LED) industry in mainland China.

Abstract:

In order to improve the scientificity of the appearance design of smart street lamps, this paper studies the appearance design method of smart street lamps combined with Kansei engineering so as to improve the appearance design effect of street lamps. Moreover, this paper optimizes the design of free-form surface optical light distribution, microlens array to improve the light extraction efficiency of high-power smart street lamps, and the heat dissipation structure of lamps. In addition, in view of the shortcoming that the direct design of free-form surface lenses for smart street lamps is not widely applicable, this paper proposes the concept of integration of microlens array packaging for smart street lamps. Finally, this paper verifies that the intelligent street lamp design based on Kansei engineering meets the lighting needs through experimental research. Through the experimental evaluation, it can be seen that the appearance design method of smart street lamps based on Kansei engineering proposed in this paper can effectively improve the structural performance of street lamps.

Abstract:

The article explores 15 terracotta oil lamps found during the archaeological excavations of the Centre for Egyptological Studies of the Russian Academy of Sciences at Kom Tuman (Memphis, Egypt). The majority of these lamps were made in moulds, and only one — on potter’s wheel. Various types of local Egyptian clays were used for the production of the lamps. Many of the lamps are decorated with various ornaments, such as palms, dolphins, torches, and, possibly, the ‘Macedonian shield’. Similar lamps were widespread in all the territory of Egypt; equally, such lamps appear among archaeological finds in the countries neighbouring with Egypt. The Memphite lamps under study were found in mixed layers and, therefore, we have compared them with analogous lamps from other locations in order to obtain more secure dating. Based on the parallels, we date the lamps to the Ptolemaic and Roman Periods (3rd century B.C. — 3rd century A.D.). The archaeological context of the lamps indicates their possible use in households and/or in temples for illumination of indoor spaces. The lamps are archaeological evidence for the existence of active everyday life at Kom Tuman in Graeco-Roman Period which is also confirmed by other sources. The study of archaeological pottery and of papyri found in the city of Memphis and in adjacent necropoleis shows that even after the foundation of the new Ptolemaic capital Alexandria, Memphis was not abandoned but continued for centuries to be a major administrative and cultic centre. The article includes the catalogue of 15 lamps with descriptions and illustrations.

Abstract:

Automation of AC and lamps is done to save energy used in everyday. In the development of AC and lamps automation need to implement a device that has the maximum function with a minimal price. Raspberry Pi is a device or module with a low price that can perform wireless communication without the help of other modules. In the development of air AC and lamps automation also required a method that is able to control the flame AC and lamps. The application of the fuzzy method can be done to collect the space state information obtained from the sensor to determine the flame of the AC and the lamps automatically. Therefore, this research proposes development of AC and lamps automation using Raspberry Pi and Fuzzy. Automation of AC and lamps using Raspberry Pi which apply Fuzzy method can save energy up to 47,22% in case of AC and 57,62% for lamps lumenation.

Abstract:

The relevance of the publication is related to the high fire hazard of lighting products. Based on the analysis of fire statistics in the Russian Federation, it is shown that the lamps occupy the fifth place among all the types of electrical installations in terms of the number of fires, direct material damage from them, as well as the number of people perished. At the same time, the number of fires at storage facilities from electrical equipment for the period 2010–2019 is about 39 %, of which the lamps account for a third of all fires. One of the significant objective reasons for such unfavorable statistics is the large number of luminaires in operation at the facilities, as well as their wide assortment and many types of design on the application area. The article summarizes the experience of recent work carried out in the field of fire hazard research of various types of lamps used for the warehouse lighting in particular, the lamps with fluorescent lamps and incandescent lamps, LED lamps and high-pressure gas discharge lamps. The physical and technical causes and possible mechanisms of ignition of these electrical products are shown. As a result of the conducted research on the example of the two most common types of lamps used in the storage facilities (with incandescent lamps and fluorescent lamps) a method for calculating the probability of fires from these products is proposed, which is fully consistent with the requirements of the current GOST 12.1.004—91 and becomes particularly relevant in the development of standards regulating fire-fighting requirements for lamps instead of GOST 17677—82, which became invalid in the Russian Federation in 2020.

Abstract:

There is an ongoing transition from high-pressure sodium lamps to LED street lamps that offer higher efficiency, cost saving and better photometric performance. This transition could lead to unintended consequences such as light flicker and extinguishing in street lighting applications when they are exposed to voltage dips. The goal of this paper is to analyse the light intensity variation of various street lamps when they are exposed to voltage dips. Several performance metrics for quantifying immunity of lamps have been proposed. Values for these metrics are obtained by applying artificial voltage dips to lamps. For voltage dips with residual voltage above 38%, lamps are immune in terms of a short-term light flicker metric. For residual voltage above 25%, light intensity reduces but without extinguishing. Compared to an incandescent lamp and high-pressure sodium lamp, LED street lamps exhibit longer zero-light intensity duration. Most of the studied LED street lamps exhibit uncoordinated light intensity drops, i.e. longer or shifted, with respect to the applied voltage dip. Individual characteristics of LED street lamps require testing before installation to prevent unexpected consequences. Recommendations are given for standardisation committees to implement an assessment method for lighting equipment.

Abstract:

<p class="emsd-body">The objective of this study is to compare the energy efficiency, potential energy savings and the environmental impact among different lighting types-incandescent lamps, CFL (compact fluorescent light) lamps and LED (light-emitting diode) lamps in a manufacturing facility. Three different tools were applied: Energy Assessment Spreadsheet (EAS), Pollution Prevention (P2) tool and GaBi 6. EAS was used to calculate the energy savings, P2 tool was used for carbon footprint analysis, and GaBi was used for the life cycle assessment (LCA) in lightings’ use phase. The results indicated a saving of over $21,000 and a reduction of 151 MT CO<sub>2</sub>e (metric tons of CO<sub>2</sub> equivalents) greenhouse gases (GHGs) using CFL in comparison to incandescent lamps. Approximately, $24,000 could be saved and 170 MTCO<sub>2</sub>e of GHGs could be reduced by using LED lamps instead of incandescent lamps every year for the operation phase of the facility. The environmental impact categories identified from the LCA in lighting use phase indicated that using incandescent lamps for the facility was much more harmful for the environment than using CFL and LED lamps. Additionally, the environmental impact from the use of LED lamps for the facility was less than that of CFL lamps.</p>

Abstract:

Lighting the lamp is an ancient tradition of Indian culture. Various cultures such as Indian, Chinese, Tibetan, Japanese, etc. widely use ghee for religious purposes. In India, Ghee is an essential component of most of the rituals. Ayurveda suggests different types of vegetative oils and ghee (clarified butter) for Ayurvedic preparations. Both ghee and peanut oil are commonly used in food preparations. Besides for eating, both ghee and peanut oil lamps are also commonly used for lighting lamps in India. Hence, evaluating the emissions from these lamps is of interest. In the present comparative study we have evaluated the emission of air pollutants: Particular Matter (PM1, PM2.5, PM10), Sulphur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone, Carbon Monoxide (CO), and Carbon Dioxide (CO2) from peanut oil and ghee lamps. We found that there was no significant difference between oil and ghee lamps for all emissions except for CO, where there was a significant reduction (15.93%, p= 0.0183) in ghee lamps compared to peanut oil lamps. Lower CO from ghee lamps than that from peanut oil lamps might be due to differences in the combustion efficiency resulting from chemical structure differences. Thus, the present finding of reduced CO emission from ghee lamps supports its wide use as a component in Indian religious purposes, Vedic-rituals of Yagya or Havan and meals.

Abstract:

This work contains analysis of characteristics of automobile lamps by Philips, KOITO, ETI flip chip LEDs, Osram, General Electric (GE), Gtinthebox, OSLAMPledbulbs with H1, H4, H7, H11 caps: luminous flux, luminous efficacy, correlated colour temperature. Characteristics of the studied samples are analysed before the operation of the lamps. The analysis of the calculation results allows us to make a conclusion that the values of correlated colour temperature of halogen lamps are close to the parameters declared by manufacturers. The analysis of the study results has shown that, based on actual values of correlated colour temperature, it is not advisable to use LED lamps in unfavourable weather conditions (such as rain, fog, snow). The results of the study demonstrate that there is a slight dispersion of actual values of luminous flux of halogen lamps by different manufacturers. Maximum variation between values of luminous flux of different lamps does not exceed 14 %. The analysis of the measurement results has shown that actual values of luminous flux of all halogen lamps comply with the mandatory rules specified in the UN/ECE Regulation No. 37 and luminous flux of LED lamps exceeds maximum allowable value by more than 8 %. Luminous efficacy of LED lamps is higher than that of halogen lamps: more than 82 lm/W and lower power consumption. The results of the measurements have shown that power consumption of a LED automobile lamp is lower than that of similar halogen lamps by 3 times and their luminous efficacy is higher by 5 times.

Abstract:

Two inoculums: Effective Microorganisms (EM) specimen available on the market and microbiological BAF1 inoculum, were applied in the experiment. The plants were cultivated in the growth chamber equipped with shelves with fluorescent or LED lamps. The highest number of inflorescences was under the influence of white color of light emitted by fluorescent lamps and blue color of light emitted by LED lamps, especially after application of BAF1 inoculum. Irrespective of microbiological inoculum, no significant effect of the color of light and type of lamps on such traits as height of leaves layer, number of leaves, greening index of leaves (SPAD) and length of inflorescences, was found. The white color light emitted by fluorescent lamps stimulated actinobacteria multiplication, especially after EM application. Regardless of the inoculum application, it was the blue color light emitted by LED lamps that stimulated the multiplication of moldy fungi. After the use of fluorescent lamps, the increase in dehydrogenase activity was observed, especially after the application of BAF1 inoculum. The activity of acid phosphatase was stimulated by blue and white+blue light emitted by LED lamps. The increase in the activity of urease was observed under fluorescent lamps emitting the green, blue and white color of light, after the application of EM.

Abstract:

The article provides a technical and economic comparison of costs when covering 10 classrooms of a general educational institution with LED and fluorescent lamps for a period of 10 years. The main advantage of led light sources is the high level of light output compared to traditional light sources. Replacing incandescent lamps and gas-discharge ICS with led ICS can significantly reduce energy costs. Currently, led ICS are increasingly replacing traditional ICS due to their high energy efficiency and safety. For comparison, luminescent lamps LVO04-4x14-031 and LED lamps DVO12-45-003 produced by JSC “Ardatovsky lighting plant” with a comparable light flux and light distribution were selected. The number of lamps in the 65 m2 auditorium was chosen based on the normalized illumination of 500 Lux on a horizontal work surface (0.8 m). The calculation of the number of lamps that meet all the requirements for lighting in General and higher educational institutions was carried out in the DiaLux 4.13 program. According to preliminary calculations, lighting with led lamps will reduce energy costs over 10 years by 2.16 times compared to fluorescent lamps. The maximum expenses are spent on the purchase of new led lamps. This is mainly due to the higher price of led lighting devices compared to fluorescent ones.

The objective of the experiments was to compare the performance of metal halide (MH) and high-pressure sodium (HPS) lamps on growth and yield of vegetables. Four experiments with lettuce were carried out. The lettuce grown under HPS lamps had a head firmness higher than under MH lamps. The difference between the type of lamps on fresh weight was not very constant with the period of production. There was no interaction between lamp and cultivar. Two experiments were carried out with tomato in Spring and Fall 1991. For a tomato crop, the yield and quality of the fruit were not affected by the type of lamps. Photosynthesis and transpiration of tomato and pepper plants were measured under MH and HPS lamps. No significant differences were found between both lamps under two humidity conditions and four PPFs. Under high humidity conditions, transpiration under MH was higher than under HPS.

Abstract:

Excavation in the temenos of Allat in Palmyra in the 1970s uncovered a deposit of clay lamps with a few vessels and coins. Inside the cella, the lamps were clustered in two groups, a few examples were found also in the temenos outside the cella. All in all, there were 191 complete and fragmentary lamps, the bulk of them made locally in Palmyra. The assemblage reveals two trends in oil lamp production: wheel-made lamps with different numbers of nozzles and imitation of imported lamps moulded from archetypes. The assemblage from the temenos is of 4th century date, but many of the moulded lamps copy Greek and Roman types from the 3rd century, with Antioch-on-the-Orontes being a highly probable source of inspiration for Palmyrean lampmakers. Special in this context are rectangular multi-nozzled lamps with relief decoration, in one case menorahs framing a scallop shell and a figural fieze, most likely a Dionysiac thiasos.
