Distribution and movement patterns are described for summering (nonbreeding) Black Guillemots in the Deer Island region of the southwestern Bay of Fundy, Canada. Guillemots were distributed in areas with moderate current velocities (range, 30–68 cm/s) and shallow to intermediate depths (range, 17–31 m). The birds appeared to avoid shallow and deep areas with fast- or slow-moving water. Guillemots preferred islands with extensive underwater ledges, presumably because these harboured sufficient prey and provided protection from fast-moving tidal waters. Guillemots moved in and out of the approaches passively with the tide and, in contrast to larids in the region, made only small-scale flights to reposition themselves in relation to food resources.

Abstract We sonically tagged and released farmed Atlantic salmon (Salmo salar) from a cage site in Cobscook Bay, Maine, USA. The fish were released in January (n = 75) and in April and May (n = 198) 2004 to study their movement patterns and survival and to assess the possibility of recapturing them. Inshore and offshore waters in this region are subject to intense tidal currents. Tagged salmon dispersed >1 km from the cage site within a few hours of their release. Mortality was high within Cobscook Bay and the surrounding coastal region (56% of the winter (January) releases; 84% of the spring (March) releases), probably the result of seal predation. Most surviving fish exited the coastal zone and entered the Bay of Fundy along the routes of the dominant tidal currents, passing through Canadian waters. No tagged fish were detected during the wild salmon spawning season in autumn 2004 in any of the 43 monitored salmon rivers draining into the Bay of Fundy, or during 2005 either in the Magaguadavic River, the site of the hatchery in which the fish were reared to the smolt stage, or by a limited coastal receiver array.

Harmonization Of Law

Abstract This paper aims to examine how to protect of artisanal fishermen fishing ground and the policies that protect them. Small-scale fisher fishing grounds has to have a special attention due to their limitation. They are using very simple fishing gear, so they can’t sail far away from the coastal waters. The Fishing law give a specific attention for this matter, by limiting fishermen with 5 gross tonnage (GT) are only able to conduct their activities within the coastal waters. This study combines legal documents and the results of interviews with fishermen on 5 GT vessel. this studi of find, then the Law Number 27/2016 changed this regulation by increasing gross tonnage for small-scale fishermen from 5 became 10 GT, and it attract more serious problems for these small-scale fishermen since they have no exclusive fishing ground anymore. It will also affect to changes of fishing lane; fishing ground and vessels authorization procedure. By increasing GT, the 10 GT vessels also have rights to sail in the same fishing ground with 5 GT vessels and it’s created a potential conflict between the fishermen. So, harmonization of law is important task for the government in avoiding the overlapping rules on vessels criteria, by choosing law that prioritize on small-scale GT vessels.

Operasional gudang memiliki berbagai aktivitas inti yang saling berkaitan satu dengan yang lainnya, seperti aktivitas receiving, storage, dan picking. Aktivitas inti ini atau yang biasa disebut inbound dan outbound harus dikerjakan dalam waktu yang singkat dan meminimalisir tingkat kesalahan agar tidak mengganggu keberlangsungan alur masuk dan keluarnya barang di gudang. Beberapa hal yang dapat mengganggu aliran barang di gudang di antaranya adalah terjadinya bottle neck di area receiving, waktu proses pencarian barang yang lama, dan 70% waktu proses order picking di bawah waktu standar. Permasalahan-permasalahan ini terjadi salah satunya dikarenakan pengelolaan barang di gudang masih manual atau belum menggunakan sistem informasi. Tujuan dari penelitian ini adalah merancang sistem informasi untuk membantu operasional gudang guna meminimalisir kesalahan-kesalahan yang dapat mengganggu aliran masuka dan keluarnya barang dari gudang, dengan menggunakan pendekatan FSN Analysis. Hasil dari pengolahan data menggunakan FSN Analysis ini, dapat membantu dalam mengetahui produk-produk yang masuk kedalam kategori fast moving, slow moving, dan non-moving.

This article focuses on how people lived in Asia Minor between about 5500 and 3000 BCE. It argues that the idea of a period dominated by small-scale, largely autarchic farming societies does not stand up to scrutiny. Although farming was of significant importance at many Chalcolithic societies in Asia Minor, the idea that wild food resources were no longer important is clearly mistaken. The Chalcolithic people were expanding their economies in multiple and often ingenious ways, and were increasingly partners in large exchange networks. Apart from farming, the exploitation of marine resources such as mollusks and fish has been documented. The rise of seafaring can be recognized through the distribution of Melos obsidian and the emergence of a cultural horizon in the northern Aegean that included western Asia Minor and the Aegean islands.

Studies of coronal transients observed in white-light (Gosling et al., 1976) have shown that fast-moving events (≤ 400 km s-1) are closely associated with flares and with type II and IV radio bursts while slow-moving events are not. We now report the first detection of the radio counterpart of a slow-moving transient. The event of 1974 January 21 is shown to be visible on maps of the quiet Sun made at a frequency of 80 MHz.

Abstract. Although slow-moving landslides represent a substantial hazard, their detailed mechanisms are still comparatively poorly understood. We have conducted a suite of innovative laboratory experiments using novel equipment to simulate a range of porewater pressure and dynamic stress scenarios on samples collected from a slow-moving landslide complex in New Zealand. We have sought to understand how changes in porewater pressure and ground acceleration during earthquakes influence the movement patterns of slow-moving landslides. Our experiments show that during periods of elevated porewater pressure, displacement rates are influenced by two components: first an absolute stress state component (normal effective stress state) and second a transient stress state component (the rate of change of normal effective stress). During dynamic shear cycles, displacement rates are controlled by the extent to which the forces operating at the shear surface exceed the stress state at the yield acceleration point. The results indicate that during strong earthquake accelerations, strain will increase rapidly with relatively minor increases in the out-of-balance forces. Similar behaviour is seen for the generation of movement through increased porewater pressures. Our results show how the mechanisms of shear zone deformation control the movement patterns of large slow-moving translational landslides, and how they may be mobilised by strong earthquakes and significant rain events.

This paper describes the locomotor movements of the tadpole larvae of the ascidians Ciona and Dcndrodoa and the associated electrical activity of the caudal muscle cells. Although very different in size and trunk shape, both larvae show essentially the same two movement patterns; symmetrical swimming and asymmetrical tail flicks. Swimming movements at tailbeat frequencies up to 40 Hz and forward speeds up to 10 L s (in the Reynold's number range 5·25) involve large lateral movements of the tail, and large yaw of the trunk. Tail oscillations are produced by muscle cells arranged in three segmented rows along the tail, coupled by gap junctions. Swimming is driven by axons innervating anterior ventral muscle cells. The second type of movement, single or multiple tail flicks, is driven by axons innervating dorsal muscle cells, all of which are innervated along the length of the tail. The middle row of muscle cells is not innervated. This small scale oscillatory swimming system is compared with those of chordates and larvacean tunicates, and it is concluded that both of these are very different from that of the ascidian tadpole.

Microearthquakes at the base of slow-moving Ice Stream C occur many times more frequently than at the base of fast-moving Ice Stream B. We suggest that the microearthquake source sites are so-called “sticky spots”, defined as limited zones of stronger Subglacial material interspersed within a weaker matrix. The fault-plane area of the microearthquakes (O(102m2)) is therefore a measure of the size of the sticky spots. The spatial density of the microearthquakes (O(10 km-2)) is a measure of the distribution of sticky spots.The average stress drop associated with these microearthquakes is consistent with an ice-stream bed model of weak subglacial till interspersed with stronger zones that support much or all of the basal shear stress. We infer a weak inter-sticky-spot material by the large distances (O(103m)), relative to fault radius, to which the microearthquake stress change is transmitted.
