The study of air fuel ratio for open furnace MILD combustion of biogas on bluff-body burner

Economical fuel cost is very critical in the heating industry. Lean combustion with high air fuel ratio (AFR) is normally practiced by the industry. Low air fuel ratio or rich combustion will result in unburned hydrocarbons (UHC). UHC is a waste and pollution to the environment. This paper discussed on the modelling of air fuel ratio for the moderate and intense low oxygen dilution (MILD) combustion of biogas on bluff-body burner. Biogas is a low calorific value (LCV) gas which was formulated by using 50% methane, 20% hydrogen and 30% carbon dioxide. AFR is the ratio of air and fuel injected to the combustion chamber. Nozzle outlet size for air and fuel plays important role to determine AFR. In this study, the air and fuel nozzle size ratio used is 23:1. The AFR will be evaluated based on the UHC produced by the combustion. Stoichiometric AFR occurred when zero UHC and zero excess oxygen flow through the EGR pipe. The result shows that when AFR is 4.0, zero UHC was detected in the EGR. UHC in EGR will be waste and create unwanted combustion at the wrong location

Moderating effect of gender and age on the relationship between emotional intelligence with social and academic adjustment among first year university students

This study examined whether emotional intelligence is significantly correlated with social adjustment and academic adjustment. It also explored the moderating effects of gender and age factors and their linked between emotional intelligence and social adjustment as well as academic adjustment among first year university students. 289 first year university students (148 males and 141 females) at the Irbid Govern Orate, North of Jordan, participate in the study and were categorized based on two age groups, younger students between the age of 18 – 25 and older students between the range of 26 and above. Two valid and reliable instruments were used to assess student’s emotional intelligence, social adjustment and academic adjustment. Correlation and multi-group analysis using structural equation model were used to analyse these data. The result shows no significant relationship between emotional intelligence and of both social adjustment and academic adjustment. In addition, the moderating effect of gender was not found. However, the moderating effect of age on the relationship between emotional intelligence with social adjustment and academic adjustment were established

Cloud Armor: a platform for credibility-based trust management of cloud services

Trust management of cloud services is emerging as an impor- tant research issue in recent years, which poses signicant challenges because of the highly dynamic, distributed, and non-transparent nature of cloud services. This paper de- scribes Cloud Armor, a platform for credibility-based trust management of cloud services. The platform provides a crawler for automatic cloud services discovery, an adaptive and robust credibility model for measuring the credibility of feedbacks, and a trust-based recommender to recommend the most trustworthy cloud services to users. This paper presents the motivation, system design, implementation, and a demonstration of the Cloud Armor platform.Talal H. Noor, Quan Z. Sheng, Anne H.H.

Mengukur Derajat Jenis Dan Fungsi Dalam Hirarki Peraturan Perundang-undangan Pasal 7 (4) Undang-undang No. 10 Tahun 2004 Tentang Pembentukan Peraturan Perundang-undangan

The error, overlapping and the error of the arrangement of the legislation in finishing law problem in the form a group and in the state, can be minimize by understanding kind, function, material content authority hierarchy and also the arrangement of the legislation.The regulation No. 10/2004, appears as the Progress that give orientation, standard for the regulation maker and the up holder of law in Indonesia. Never the less, there is some thing that have to be analyzed deeply and decide the degree of the kind of the legislation arrangement in which it is explained in section 7 (1) jo section 7 (4) jo section 7( 5) about the kind and the hierarchy of the legislation arrangement in Indonesia.The decision of the position of the legislation arrangement in hierarchy of the legislation arrangement is placed in the context of the formal valid of the legislation arrangement such as Lex superior Derogat Lex Inferior Lex Specialis Derogat Lex Generalis and also Lex posteriori Derogat Lex Priori. So the decision of the position of the legislation arrangement is devised based on the legislation arrangement which command in the hierarchy of the legislation arrangement

Measurement of NO2 indoor and outdoor concentrations in selected public schools of Lahore using passive sampler

Higher levels of NO2 are a danger to human health especially for children. A seven day study was carried to find out the ambient concentrations of NO2in 27 schools of Lahore with the help of passive samplers. In each school three sites were selected, viz: laboratory, corridor and outdoors. After 7 days exposure the tubes were subjected to spectrophotometric analysis. Results showed that the maximum values measured in laboratory, outdoor and corridors were 376µg/m3 , 222µg/m3 and 77µg/m3 . Minimum values for laboratory, outdoor and corridors were 10µg/m3 , 20µg/m3 and 8µg/m3 . Factors affecting these values were laboratory activities and proximity to main roads. These values were significantly higher than the standard values defined by EPA. Therefore children in schools were at risk of developing health complications

Reorientasi Penguatan Kekuasaan Kehakiman Melalui Independensi

Reorientasi penguatan kekuasaan kehakiman melalui independensi komisi yudisial mengurai dan menjelaskan persoalan penguatan fungsi pengawasan kepada aktor utama penegakan wibawa hukum dan keadilan. Komisi Yudisial yang lahir melalui amandemen UUD 1945 adalah lembaga negara yang independen, memiliki fungsi dan wewenang pengawasan terhadap hakim. Komisi Yudisial secara kelembagaan memang independen, tetapi fungsi wewenang dan tugas pokoknya lebih pada persoalan wilayah penjagaan citra kehormatan dan perilaku hakim, yang justru persoalan inti dari pengawasan yang secara filsofis paradigmatis perlu selalu diupayakan oleh seluruh lembaga pelaku dalam penegakan hukum bahkan oleh setiap pejabat, lembaga negara juga masyarakat. Komisi yudisial dibentuk sebagai diskursus dari pemikiran fungsi pengawasan yang sebenarnya bagian dari kewenangan di Mahkamah Agung untuk melakukannya. Persoalan pengawasan intern terhadap hakim yang dulu dilakukan oleh eksekutif/pemerintah (melalui departemen kehakiman) adalah merupakan pemotongan wewenang kekuasaan yudisial oleh pemerintah orde baru. Kemudia melalui UU MA segala fungsi dan Wewenang yang memberikan jaminan independensi MA dikembalikan, akan tetapi fungsi pengawasan ini sudah lemah sejak masih ketika berada di tangan eksekutif.Reorientation of strengthening the independence of judicial power through the judicial commission to parse and explain issues to the strengthening of the oversight function main actors of law and justice enforcement authority. Judicial Commission that was born through the 1945 amendment is an independent state institution, has the function of supervision and authority of the judge. Institutionally Judicial Commission is independent but functions substantially more authority and duty to question the image of the honor guard and the behavior of judges, just the core issues of oversight that philosophically paradigmatic should always try by all actors in the law enforcement agencies and even by any officials, state agencies community as well. Judicial Commission of mind discourse dibentuksebagai actual function of this part of the supervisory authority in the Supreme Court to do so. Internal control issues to the judge who once performed by the executive / government (through the Justice Department) is the authorized withholding judicial power by the government of the new order. Then through the Supreme Court Act all the functions and authority that guarantees MA indepensi restored, but the oversight function has been weakened since died while in the hands of the executive
