    his paper presents detailed study of biogas reforming. Model biogas with different levels of H2S is subjected to reforming reaction over supported Ni catalyst in a fixed bed reactor at 700 °C and 800 °C. In order to understand the poisoning effects of H2S the reactions have been initially carried out without H2S in the feed stream. Three different H2S concentrations (20, 50 and 100 ppm) have been considered in the study. The H2O to CH4 ratio is maintained in such as way that CO2 also participates in the reforming reaction. After performing the poisoning studies, regeneration of the catalyst has been studied using three different techniques i) removal of H2S from the feed stream ii) temperature enhancement and iii) steam treatment. Poisoning at low temperature is not recoverable just by removal of H 2S from the feed stream. However, poisoning at high temperature is easily reversed just by removal of H2S from the feed stream. Unlike some previous reports by Li et al. (2010) and Rostrup-nielsen (1971) [1,2], catalyst regeneration is achieved in shorter time frames for all the regeneration techniques attempte

    Preeclampsia is a systemic disorder 20 weeks of gestation, characterized by a BP 140/90 mmHg and proteinuria. These abnormalities can affect both the mother and fetus. The cause of preeclampsia was still unknown. Several studies have reported different results regarding the risk factors associated with preeclampsia. Therefore, research about the factors that influence preeclampsia at the Cipamokolan Health Center needs to be carried out to determine further prevention programs. The case-control was used as the study design. The population is all pregnant women data in the Cipamokolan Health Center during the past year. The study sample was taken by purposive sampling based on the specified criteria. A total of eighteen respondents were recruited in the case group and 97 respondents in the control group. Data obtained secondary from medical records. The data were analyzed using the Chi-Square. The results showed a relationship between maternal age and preeclampsia (p-value = .036 .050), and there was no relationship between gravidity and pregnancy intervals with preeclampsia in pregnant women at the Cipamokolan Health Center. A pregnancy spacing program is recommended to avoid preeclampsia during pregnancy.

One can say it the character hi hasmanaged to absorb the values and beliefs. Covication people desired, and serve asa amoral in this life. Therefore researchers feel the need to develop a material on theformation of character values in aspects toleranse, care for environment , social care.Which is expected to he used by guidance and counseling teachers to teach theirstudents. There materials were prepared using the methods of research anaddevelopment (R&D).as for the purpose of research is as follows.1)arragement of thematerials on the formation of characters values in aspects toleranse, care forenvironment, and social care necessary for SMK student in terms of clarity, systematic,image support freshness completeness of the materials and support for the materialsand support for imagges or video and games.2)know the quality of the materialproduced. This material consist of understanding the character, the values of characterprincipples the factors that influence the formation of character tolerance, care forenvironment, social care.

    Setiap sumur produksi yang akan diproduksikan diharapkan fluida akan mengalir kepermukaansecara alami. Proses ini akan berlangsung sampai pada satu titik dimana tekanan reservoir akanberkurang dengan berjalannya waktu, sehingga kemampuan sumur produksi untuk mengangkatfluida ke permukaan akan berkurang atau berhenti sama sekali.Oleh karena itu dibutuhkan metodepengangkatan buatan dimana salah satunya dengan menggunakan pompa ESP. Berdasarkanpengamatan data teknik sumur BN-23, BN-35 dan BN-104 sangat cocok untuk diterapkan untukoptimasi produksi. Berdasarkan hasil perhitungan kurva IPR dengan menggunakan metoda Vogel,laju produksi maksimum (Qmaks) yang dicapai sumur BN-23, BN-35 dan BN-104 adalah masing–masing sebesar 1661 BFPD, 6446.7 BFPD, dan 1001 BFPD. Selanjutnya melalui pendekatandengan persamaan empiris didapatkan laju produksi optimum (Qo) sumur BN-23, BN-35 dan BN-104 adalah masing-masing sebesar 176 BBD, 193 BBD, 193 BBD dengan water cut masing–masing 91.2 %, 94.2% dan 84% maka dihasilkan minyak sebesar 1998 BOPD, 3333 BOPD dan1209 BOPD. Untuk mencapai laju produksi optimal sumur produksi tersebut maka disarankan padasumur BN-23 untuk mengunakan jenis pompa ESP REDA Type IND 2000 stage sebesar 119 danrange capacity 1300-2600 bfpd, Sumur BN-35 untuk mengunakan jenis pompa ESP REDA TypeING 5200 stage sebesar 119 dan range capacity 2000-3600 bfpd, dan Sumur BN-104 untukmengunakan jenis pompa ESP REDA Type IND 1300 stage sebesar 119 dan range capacity 600-1250 bfpd
