Study of performance of nitrification process

AbstractThe objective of this paper was to study the static behavior and the performance of an experimentally validated model for nitrification process using a single reactor high activity ammonia removal over nitrite (SHARON) process. The model consists of mass balances of total ammonium, total nitrite, ammonium oxidizers, and nitrite oxidizers. The steady state analysis allowed the construction of practical diagrams that show the effect of operating conditions (dilution rate and ammonium feed concentration) as well as kinetic parameters on the performance of the bioreactor. The focus is made on the region that allows for the conversion of ammonium to nitrite and the prevention of further oxidation of nitrite to nitrate. The findings of this study are applicable which can delineate the effect of process variables on the performance of the bioreactor

Populasi dalam penelitian ini adalah seluruh siswa kelas VII SMPN 8 Palangka Raya yang beragama Islam sebanyak 201 Siswa, Analisis data melalui beberapa tahapan yaitu Editing, Coding, Tabulating dan Analyzing. Hasil penelitian menyatakan bahwa; (1) Hasil belajar dari hasil tes diperoleh nilai rata-rata 76.617 sedangkan Nilai KKM 80. 48.259% (97 orang siswa) memperoleh nilai di atas nilai KKM, 51.741% (104 orang siswa) memperoleh nilai di bawah nilai KKM, (2) Dari hasil pengukuran perilaku siswa diperoleh rata-rata sekor 66.412, dari rata-rata diatas dapat diketahui bahwa siswa yang berada diatas rata-rata sebanyak 103 orang siswa dari 201 siswa sedangkan siswa yang berada di bawah rata-rata sebanyak 98 orang siswa dari 201 orang siswa; (3) Pengaruh hasil belajar terhadap perilaku siswa dari hasil korelasi yang telah dihitung ternyata tidak ada hubungan yang signifikan antara prestasi belajar Pendidikan Agama Islam Materi Perlaku terpuji dengan perilaku siswa SMPN 8 Palangka Raya, dimana hasil perhitungan korelasi product moment rxy = 0,102 kurang dari nilai r tabel pada tabel product moment N = 201 dengan taraf signifikansi 5% yaitu sebesar 0,138 dan taraf segnifikan 1% 0,181 sehingga hipotesis penulis tidak terbukti

Algorithm for Coding Person’s Names in large Databases / Data Warehouses to Enhance Processing Speed, Efficiency and Reduce Storage Requirements

oai:ojs2.lgurjcsit.lgu.edu.pk:article/1A technique to codify the names of people in Databases andData warehouses to reduce the storage requirements and enhanceprocessing speed is presented. It is estimated that the storage requirementcan be reduced, which is normally dominated by the entries of first name,middle name and last name and storage requirements for Datawarehouses keep on increasing. The scheme of the Algorithm replacesthe first name, middle name and last name in numeric charterers insteadof alpha characters for storage. It decodes them into actual AlphaCharacters at the time retrieval

Scenario of Land Diversification to Words Apple Orchards in Jammu and Kashmir-India

In this paper an attempt has been made to understand the patterns and determinants of crop diversification in Jammu and Kashmir agriculture. The State is depended on subsistence farming without any positive response, but from last few decades a great change has taken place in the variety of crops like Apples. Its Cultivation is dominant occupation in the state, directly or indirectly supports about 81% of total population of the state, which shows the over dependence of the state on agriculture. The cropping pattern is influenced by Geographical, physical, technological and institutional factors like land reformation, consolidation of holdings and credit facilities, price structure, procurement policies and storage facilities. The study revealed that the crop sector of Jammu and Kashmir agriculture at an aggregate level is gradually diversifying in favor of high-value crops like Apples.

ANALYSIS OF SHARIA MARKETING MIX AND SERVICE QUALITY TOWARDS CUSTOMER SATISFACTION AT GRESIK VIVI DRINKING WATER REFILLING STATION

This research is conducted to help customers in delivering the complaints in the form of product quality and the way of providing services of the subject research and the improvement of it using sharia marketing mix perspectives and service quality. This research is a quantitative study using the Partial Least Squares (PLS) method. The data collection method comes from primary data of distributing questionnaires to 126 respondents of Gresik Vivi Drinking Water Refilling Station customers. The results of this study indicate that product quality (X1), Price (X2) and Promotion (X4) have no significant effect on customer satisfaction (Y) and in the other words those variables need to be high concern of the owner of business to handle the improvement or handling the customer complaints. Meanwhile, the location (X3) and the service quality (X5) have a significant effect. This is indicated that those variables are more suitable for the customer satisfaction and need to be maintained by the owner in developing the business.Â

Effect of Problem solving teaching strategy on 8th Grade students’ attitude towards Science

The study was conducted to explore, ‘The effects of problem solving teaching strategies on 8th grade students’ attitudes toward science’. Pre-test, post-test design was selected for this study. Experimental group was exposed to problem solving teaching strategies, while the control group was instructed using traditional teaching methods. The study was conducted with 60 students 30 in each experimental and control group at a public high school at Islamabad the federal capital of Pakistan. A scale regarding attitude towards science learning (AtSL) with Cronbach’s alpha 0.86 was administered to the students of both experimental and control groups. Data obtained was analyzed using t test. The findings indicated that student in experimental group made positive improvement in attitude towards science learning as compared to students in control group. Hence, it is recommended that science teachers’ may incorporate problem solving teaching strategies in their teaching to improve students’ attitude towards science. Key words: problem solving, attitude towards science learning (AtSL
