Because horizontal gene transfer can confound the recovery of the largely prokaryotic tree of life (ToL), most genome-based techniques seek to eliminate horizontal signal from ToL analyses, commonly by sieving out incongruent genes and data. This approach greatly limits the number of gene families analysed to a subset thought to be representative of vertical evolutionary history. However, forma...

Proyek pembangunan jalan tol merupakan proyek infrastruktur strategis, dikarenakan strategis Nasional sehingga pemerintah membuat Program Percepatan Pembangunan Jalan Tol sepanjang lebih kurang 1100 km agar dapat segera difungsikan
 Salah satu metode yang digunakan untuk melakukan analisa percepatan tersebut adalah Analisis Pertukaran Waktu dan Biaya (Time Cost Trade Off Analysis) diolah d...

For a long time, it was politically incorrect to speak about adaptation to climate change, because it presumably implies accepting defeat in the battle against evil emissions (Burton, 1994). This has changed, perhaps because scientists repeatedly pointed out that climate change cannot be altogether avoided even if we try very hard (Parry et al., 1998; Wigley, 1997), and perhaps because George W...

N-Aryl-S,S-dimethylsulfimides 3(Ar = 4-NO(2)C(6)H(4)), 4 (Ar = Ph) and 5 (Ar = 4-Tol)react with Appel salt 1 to give the corresponding N-aryl-(4-chloro-5H-1,2,3-dithiazolylidene)benzenamines 8 (Ar = 4-NO(2)C(6)H(4)), 9 (Ar = Ph) and 10 (Ar = 4-Tol) in 84, 94 and 87% yields, respectively. The reaction proceeds in the absence of base and a proposed reaction mechanism is given.

Salah satunya dalam bidang transportasi yaitu pembangunan Jalan Tol Kayu Agung – Palembang Betung. jalan tol ini merupakan bagian untuk peningkatan kebutuhan akan prasarana raya Lintas sehingga diharapkan bisa mengatasi permasalahan kemacetan yang terjadi pada ruas utama. Adanya Trans dapat meningkatkan pertumbuhan ekonomi dae...

The concept of the TOL introduced by Darwin, captured in the famous single illustration of the On the Origin of Species (Darwin 1859), and used by Haeckel as the grand scheme of the history of the actual life-forms is the cornerstone of evolutionary biology and, arguably, of biology in general. For nearly 140 years after the publication of the Origin, phylogenetic trees, which were initially co...

Detection of a large void (∼7 Mpc) is reported between the redshifts 2.16286 and 2.20748 in the Ly α forest of TOL 1038-2712. This void is centered near a foreground QSO TOL 1037-2704 which is at a distance ∼4.4 Mpc away from the void. The estimated probability for the void to occure by chance in front of the foreground QSO is few times 10 −3. Various implications of the void being produced by ...
