Migrasi ke energy alternatif

Krisis energi global dan pemanasan global yang terjadi menyebabkan pemerintah Indonesia dan dunia mulai melakukan penghematan terhadap sumber daya energi tak terbarukan (minyak bumi, gas alam, dan batubara), dan penghematan energi listrik yang sebagian pembangkitnya memakai bahan bakar minyak dalam memproduksi energi listriknya. Selain cadangan energi konvensional dengan bahan sumber energi fosil di Indonesia yang sudah semakin menipis, tingginya harga minyak dunia menyebabkan pasokan listrik dari PLN menjadi berkurang. Dampaknya adalah kelangkaan energi BBM dan naiknya harga kebutuhan konsumsi, serta makin rendahnya akses masyarakat terhadap energi. Kelangkaan energi listrik ini mengakibatkan adanya kebijakan pemadaman bergilir, serta perubahan jadwal kerja industri yang menuai banyak kontroversi. Padahal pemadaman listrik di Jakarta akibat pemadaman kawasan Jakarta berpotensi menimbulkan kerugian sebesar Rp. 1 triliun dan 500 industri besar terganggu (Kompas, 13 Oktober 2009).
Industri pertambakan dan perikanan air payau juga mengalami kerugian. Kerugian ini dapat ditinjau dari 2 sisi dimana jika pertambakan tersebut menggunakan energi listrik untuk memompa air maka pemadaman listrik akan menjadi ancaman. Namun jika proses dalam pertambakan menggunakan diesel dalam memompa air yang menggunakan solar, maka kelangkaan bahan bakar minyak menjadi momok yang menakutkan.

Embryology

THE TERM Embryology, in its widest sense, is applied to the various changes which take place during the growth of an animal from the egg to the adult condition: it is, however, usually restricted to the phenomena which occur before birth. Embryology may be studied from two aspects: (1) that of ontogeny, which deals only with the development of the individual; and (2) that of phylogeny, which concerns itself with the evolutionary history of the animal kingdom. 1
In vertebrate animals the development of a new being can only take place when a female germ cell or ovum has been fertilized by a male germ cell or spermatozoön. The ovum is a nucleated cell, and all the complicated changes by which the various tissues and organs of the body are formed from it, after it has been fertilized, are the result of two general processes, viz., segmentation and differentiation of cells. Thus, the fertilized ovum undergoes repeated segmentation into a number of cells which at first closely resemble one another, but are, sooner or later, differentiated into two groups: (1) somatic cells, the function of which is to build up the various tissues of the body; and (2) germinal cells, which become imbedded in the sexual glands—the ovaries in the female and the testes in the male—and are destined for the perpetuation of the species. 2
Having regard to the main purpose of this work, it is impossible, in the space available in this section, to describe fully, or illustrate adequately, all the phenomena which occur in the different stages of the development of the human body. Only the principal facts are given, and the student is referred for further details to one or other of the text-books 1 on human embryology

3 Most Favorites Sample Book

Just for this Blog I had to share many sample book. Actualy sample books For Biophysics.

1. This Book Is introduction to Molecular organism for viewing in Biophysics studies, all of us know how to studied biology. But this book is expert to explained about molecular studies for biology and physics.
   
2. Are You Famous?? Now we can exist for social networking. However some this time we must connected internet, and one off most popular dirrect chat room in My contry is Yahoo Messenger this book actually sample. And just including in Indonesians Leanguage.
3. After lesson in our class sometime we build Blog and Forum. so Just check this sample

This posting is starting from Lab BLog Team. rusli so Just check that samples

Thanks
