ABSTRACT Texaco Brazil S.A. (TBSA), a ChevronTexaco Company, is a far reaching operation consisting of ten company owned bulk plants and one joint venture/company operated bulk plant. Five of these bulk plants are located in the southern half of the Country and are not near any major bodies of water. The other six bulk plants, including the joint venture facility, are located in the northern half of the Country either within the Amazon Basin or on the Atlantic coast: All have waterfront transfer operations.

<strong><em>Abstract</em></strong> <em>Transportation of bulk cargoes by the fleet of tankers is carried out in different climatic zones with significant fluctuations in the ambient temperature. At the same time, bulk cargo will increase its volume when its temperature increases. There is a risk of the cargo spilling onto the ship's deck. When transporting any bulk cargoes, it is allowed to use only 98% of the cargo capacity of the tanker, the remaining 2% is called the safety factor, i.e. the reserve volume for unforeseen expansion of the cargo when sailing in different climatic zones.</e

The correct loading of bulk carriers is essential for their maritime safety. Inadequate loading can lead to various risks, including compromised hull strength, reduced stability and violation of the vessel's seaworthiness. Existing shipboard instruments do not allow for timely planning and real-time control of loading operations, which can lead to potential risks. The high intensity of loading operations at dry bulk terminals exacerbates the problem, as there is often insufficient time to adequately prepare and verify loading plans, increasing the risk of overloading cargo holds.

The nautical safety of bulk carriers is largely determined by their correct loading. The available ship's instruments do not allow timely planning of loading operations and real-time control of the ship's condition during their execution. The ship's officers in charge have to spend a lot of time preparing the loading (unloading) plans. The high intensity of cargo operations at modern dry bulk terminals and the lack of sufficient time to prepare and verify the new cargo plan may create a risk of cargo holds being overloaded. This may lead to a deterioration of the local and longitudinal strengt

To date, microscale and nanoscale optomechanical systems have enabled many proof-of-principle quantum operations through access to high-frequency (gigahertz) phonon modes that are readily cooled to their thermal ground state. However, minuscule amounts of absorbed light produce excessive heating that can jeopardize robust ground-state operation within these microstructures. In contrast, we demonstrate an alternative strategy for accessing high-frequency (13 GHz) phonons within macroscopic systems (centimeter scale) using phase-matched Brillouin interactions between two distinct optical cavity

ABSTRACT Planted forests occupy more than 6.5 million ha in Brazil, where harvest and logging operations are performed with increasingly heavier machinery, increasing the risk of soil compaction. Soil compaction can be avoided if soil load bearing capacity is not exceeded, what makes it important to assess both the soil strength and the impact of different operations. The aim of this study was to evaluate the load bearing capacity of some coarse textured soils (two Hapludult and one Haplorthod) in two soil horizons (BA and B), from northeastern Brazil; and to assess the impact of harvest and l

Recent research has focused on sheet shear cutting operations. However, little research has been conducted on bar shear cutting. The main objective of the present investigation is to study bar shear cutting with numerical and experimental analysis. Bar shear cutting is an important operation because it precedes bulk metalworking processes for instance machining, extrusion and hot forging. In comparison to sheet shear cutting, bar shear cutting needs thermomechanical modelling. The variational formulation of the model is presented to predict damage mechanics in the bar shear cutting of aluminiu

Manufacturing of functional sheet metal products by forming can be realised with the application of conventional bulk forming operations on sheet metals. The challenges of those sheet bulk metal forming processes are high resulting forming forces and the demand on a specific control of material flow. To meet these challenges well-directed thinning of blanks as well as accumulations of material to form functional elements is employed. Due to local loads, simultaneous 2D and 3D stress and strain states occur. Process adapted semi-finished products, containing a defined sheet thickness characteri

A field experiment was conducted to evaluate the performance of locally developed combine equipment used for several agricultural operations at once in a silt clay loam soil texture. Three factors were used. The first is the forward speed of the machinery unit, with three speeds: of 2.98, 4.37, and 6.18 km h-1, the second is plowing depths, with three plowing depths and subsurface irrigation pipes of 10/20, 15/25, 20/30 cm, the third is the distances between the subsurface irrigation pipes, with three distances of 50, 60 and 70 cm. The field efficiency of the combine equipment, soil moisture c

Due to ecological and economic challenges there is a growing demand for lightweight construction by using closely-tolerated complex functional components with variants. Conventional sheet and bulk metal forming operations are often improvident in producing such parts. A promising approach is the process-class “sheet-bulk metal forming” (SBMF). Within SBMF bulk forming operations are applied to sheet metals, often in combination with sheet forming operations [1]. This leads to a significant gradient in load conditions regarding stress and strain states and causes locally varying tribological co

The proposed experimental method of determining the losses of bulk cargo prone to dust formation allows, based on model researches results, to predict the bulk cargo losses amount when working with a grab in real conditions of cargo operations. The article presents developed by the authors experimental equipment, which makes it possible to obtain physical models of cargo scooping and unloading the grab processes, during which the most intense dust formation and the maximum losses amount of the reloaded cargo occur. In addition, the methods of using the specified experimental equipment are give

Shared data object implementations that allow non-blocking concurrent operations are useful for in-memory data-processing, especially when they support consistent bulk operations like iterations. We propose an algorithmic implementation for concurrent iterators on shared double-ended queues (deques), building on and complementing a known lock-free deque implementation by M. Michael. The proposed construction is linearizable and wait-free. Moreover, it is read-only, so it does not execute expensive synchronization primitives and it does not interfere with update operations.

The research on dry bulk terminal improvement is currently limited and lacks focus, despite the increasing global demand for dry bulk cargo. The primary aim of this paper is to propose a design for enhancing dry bulk terminal operations and identify a significant factor for improving dry bulk terminal performance through the utilization of the Quality Function Deployment (QFD) method. The fundamental concern in QFD pertains to determining the customer’s desires and formulating an effective strategy to address the identified challenges. These two elements are of utmost importance and are consid
