"Elizabeth Grossman shows that for the sake of convenience, efficiency, and short-term safety, we have created synthetic chemicals that fundamentally change, at a molecular level, the way our bodies work. The consequences range from diabetes to cancer, reproductive and neurological disorders.A scientific revolution is introducing products that are “benign by design,” developing manufacturing processes that consider health impacts at every stage, and is creating new compounds that mimic rather than disrupt natural systems. Through interviews with leading researchers, Grossman gives us a first look at this radical transformation."

"This new edition of a widely-read and highly-acclaimed book broadens the scope of its predecessors from a heavy focus on industrial chemicals as toxicants to include drugs, food additives, cosmetics and other types of compounds that people are exposed to daily. Also new to the 3rd edition are newer issues-of-the day such as nanoparticulate toxicants, second hand smoke, food contamination, lead in toys, and others. As such, the book provides the basics of toxicology in easy-to-understand language as well as a fuller understanding of the daily insults to which our bodies are subjected."

"Pada penelitian ini, sintesis nanopartikel ZnO, Co2SnO4, dan nanokomposit ZnO/Co2SnO4 dilakukan secara green synthesis menggunakan ekstrak daun talas (Colocasia esculenta L. Schott) dalam sistem dua fasa (n-heksana – air). Kandungan metabolit sekunder yang terdapat pada ekstrak daun talas seperti alkaloid dan saponin akan berperan sebagai sumber basa lemah dan capping agent dalam proses sintesis. Selanjutnya, hasil sintesis akan dikarakterisasi dengan menggunakan Spektrofotometer UV-Vis, Spektrofotometer UV-Vis DRS, Spektroskopi FTIR, X-Ray Diffraction (XRD), dan Transmission Electron Microscopy (TEM). Berdasarkan hasil karakterisasi dengan spektrofotometer UV-Vis DRS didapatkan nilai band gap energy untuk nanopartikel ZnO, Co2SnO4, dan nanokomposit ZnO/Co2SnO4 masing-masing sebesar 3,08 eV, 1,6 eV, dan 2,44 eV. Nanokomposit ZnO/Co2SnO4 diuji aktivitas fotokatalitiknya terhadap malasit hijau. Berdasarkan hasil penelitian, uji aktivitas fotokatalitik nanokomposit ZnO/Co2SnO4 memiliki persen degradasi tertinggi pada kondisi optimum dengan berat sebesar 12 mg pada 5,0 x 10-6 M malasit hijau selama 120 menit di bawah sinar tampak, yaitu sebesar 92,63%.

In this research, synthesis of ZnO, Co2SnO4 nanoparticles, and ZnO/Co2SnO4 nanocomposites were prepared by green synthesis using taro (Colocasia esculenta L.Schott) leaf extract in a two phase system (n-hexane – water). The content of secondary metabolites found in taro leaf extract such as alkaloid and saponin were roled as a source of weak base and capping agent in the synthesis process. Furthermore, the synthesis results were characterized by UV-Vis spectrophotometer, UV-Vis DRS spectrophotometer, FTIR spectroscopy, X-Ray Diffraction, and Transmission Electron Microscopy. UV-Vis DRS spectrophotometer characterization shows that band gap energy of ZnO, Co2SnO4 nanoparticles, and ZnO/Co2SnO4 nanocomposites were 3,08 eV, 1,6 eV, and 2,44 eV, respectively. ZnO/Co2SnO4 nanocomposites was applied for its photocatalytic activity to malachite green. Based on research results, the photocatalytic activity test of ZnO/Co2SnO4 nanocomposites had the highest degradation percentage of malachite green reached in the optimum condition of 12 mg mass catalyst and 5,0 x 10-6 M of malachite green concentration for 120 minutes under visible light, which was 92,63%."

"Kebutuhan masyarakat terhadap pelayanan yang optimal dari rumah sakit terus mengalami peningkatan yang selanjutnya menimbulkan tuntutan untuk mengembangkan kualitas pelayanan atau peningkatan kualitas pelayanan. Melakukan pengembangan investasi pada rumah sakit tentunya tidak dapat dilakukan sembarangan, seorang manajer harus mampu meminimalkan risiko-risiko yang terjadi agar dapat menghasilkan analisa investasi yang baik dan cermat. Adanya rencana pengembangan Rumah Sakit Pengayoman Cipinang untuk peningkatan pelayanan kesehatan kepada Narapidana/Tahanan/Anak Didik Pemasyarakatan/Deteni Imigrasi membutuhkan penambahan sumber daya manusia. Tujuan dalam penelitian ini adalah menganalisis kelayakan pengembangan Rumah Sakit Pengayoman Cipinang sehingga dapat menjadi informasi berbasis bukti yang dapat digunakan sebagai acuan dan pertimbangan dalam mempersiapkan pengembangan Rumah Sakit.

Society needs for optimal service from hospitals continue to increase which further raises demands for developing service quality or improving service quality. Developing investments in hospitals certainly can not be done carelessly, a manager must be able to minimize the risks that occur in order to produce a good and accurate investment analysis. The Planning of Pengayoman Cipinang hospital to upgrade its health services for prisonersneed more human resources. The purpose of this study is to analyze the feasibility of Pengayoman Cipinang hospital so that it can be evidence-based information that can be used as a reference and consideration in preparing for hospital quality improvement. This research is an operational research by conducting research on external and internal aspects of Pengayoman Cipinang hospital. The results showed that increasing the class of Pengayoman Cipinang Hospital is necessary, so that their prisonner can get good health services, because getting health services is the right of every community."
