We have observed the dark cloud Barnard 68 with SCUBA at 850 µm and with SIMBA at 1.2 mm. The submillimetre and millimetre dust emission correlate well with the extinction map of Alves, Lada, & Lada (2001). The A V /850 µm correlation is clearly not linear and suggests lower temperatures for the dust in the inner core of the cloud. Assuming a model for the temperature gradient, we derive the cl...

There are at least 2 distinct mechanisms for the formation of young massive clusters (YMC), all of which require galactic-scale processes. One operates in harrassed fragile galaxies, in the dense cores of low mass galaxies, at the ends of spiral arms, or in galactic tidal shocks where transient and peculiar high pressures make massive clouds at high densities. The result of this process is usua...

A scalable laser-based timing analysis technique we call laser assisted device alteration (LADA) is introduced for the rapid isolation and analysis of defect-free performance limiting circuits in advanced flip-chip packaged microprocessors and other complex IC’s. The technique, which has been demonstrated to be widely applicable to production level as well as motherboard/system level testing, u...

Arecibo high-resolution radar images of the southern hemisphere of Venus extending to 78 degrees S show that the surface of the Themis-Alpha-Lada region is characterized by linear deformation zones with volcanoes and corona-like features and by regional volcanic deposits (primarily plains, small shields, and large edifices). Large-scale areal deformation is limited to the tessera of Alpha Regio...

A right ventricular (RV) myocardial infarction (MI) may yield precordial ST-segment elevation (STE). Accordingly, combined inferior and precordial STE may be produced during an inferior-RV MI. Such an electrocardiographic picture may be mistakenly regarded as showing wrapped left anterior descending artery (LADA) occlusion or double vessel occlusion. We present a patient with inferior-RV MI and...

cardial infarction was admitted to the catheterization laboratory for primary percutaneous coronary intervention. Left anterior descending artery (LADa) was seen subtotally occluded immediately after the first diagonal artery (D1a) branching with TIMI 1 distal flow on coronary angiogram (Fig. 1a–c, Video 1–3). LADa and D1a were passed by a soft guidewire. After predilatation of the culprit lesi...

Abstrak Kebutuhan lada dunia mencapai 350.000 ton/tahun. Kontribusi Indonesia sebagai pengekspor sebesar 29% dari kebutuhan dunia. Produksi nasional tahun 2014 91.941 ton. Karena produksi lebih sedikit dibandingkan dengan permintaan maka diperlukan cara untuk mengoptimalkan lada. tanaman dipengaruhi oleh pertumbuhan pada tanaman, ada dua faktor yang memepengaruhi pertama pembibitan dan ketersed...
