The lower block of the Denholm landslide has moved 370 m over alluvium deposited by the North Saskatchewan spillway and river during the last 11 500 years at an average rate of 32 mm/year. These values must be considered minimal because erosion of the toe of the landslide is required for the formation of retrogressive landslides. The shear strength for the bedrock clay (shale) of the Lea Park Formation was back calculated to be [Formula: see text] assuming zero cohesion. Key words: retrogressive landslide, clay shale, residual strength, movement rates, geological age, inclinometer.

Urease Enzyme

In recent years, utilization of biotechnology in geotechnical field has rapidly grown. One of the biotechnologies being utilized is urease enzyme, a stabilization material by bio-cementation method studied in this research.  Urease enzyme is manually mixed with additional 10% of clay soil to clay shale. The objective of mixing it is to increase the bearing capacity of the clay shale. Consolidated undrained triaxial test was performed for testing the soil strength performance for samples that had undergone curing for 2, 4, and 6 weeks. The results indicated that the sample stiffens, proved by the increase of shear strength from consolidated undrained triaxial test. The shear strength value produced by the variation of the urease enzyme mixture + 10% the clay is higher than that of without the original clay shale.

Cretaceous Period

The development of the area, of the Thames Estuary is briefly traced since the late Cretaceous period, with its present outline being due to a combination of factors. The overall subsidence of the North Sea area, the ‘Alpine5 fold movements, and the transgression of the sea since the retreat of the Weichselian icesheets have all contributed. The positions of the shore-line during the critical phase, 9600 b.p. to 8000 b.p., of this last transgression of the sea are shown. Subsequent to this main transgressive phase, erosion of the shoreline has been rapid due to storm-waves and tidal current action. An estimation of the average rate of subsidence and/or sea-level rise is given based on the concept of sedimentary equilibrium in which a figure of 12.7 cm (5 in) per century is arrived at.

Weathering Process

Clay shale is a claystone which in fresh condition has a very high shear strength. When it reacts with the atmosphere or hydrosphere it will weather so that the shear strength of clay shale will drop drastically. The weathering potential of clay shale is generally done by the slake durability test and the weathering process is measured by disintegration ratio test (DR). The strength of clay shale that has fully weathered will increase again when it is stabilized with a minimum of 6% PC (Portland Cement). It was found from the wetting drying cycle process testing that durability of re-weathering of stabilized clay shale with PC is increased compared to natural clay shale. Disintegration ratio of natural clay shale DR was smaller than stabilized clay shale with 6% PC. Additionally, more than 6% PC increased the durability of re-weathering of clay shale.

Sea horse Hippocampus spp. is a group of unique marine biota and its distribution is spread all over the world. This study aims to determine the characteristics of seahorse Hippocampus comes from North Bintan waters by looking at the yield and degree of hydrolysis (DH) of the protein hydrolyzate sample. This samples obtained from the catch of fishermen in the North Waters of Bintan Island. The analysis is the measurement of the yield and the degree of hydrolysis. The results obtained from the study that the horse of sea H. comes from the North waters of Bintan shows that the highest yield in the sea horse body is bone that is equal to 43.69%. This proves that the seahorse is one of the ingredients that can be utilized as a further processed dry feed such as in the manufacture of flour and dried products (such as ginseng). As for the degree of hydrolysis generated from the substrate of H. comes a sea horse protein derived from meat and bone have a high value compared to the substrate of sea horse bone meal. Key words: sea horse, yield, degree of hydrolysis, North Waters of Bintan Island

The diabetic foot can be treated only if you know how to work as a team and the diabetologist, the natural referent of the clinical case, has to create a multiprofessional/multidisciplinary team that can manage the patient to prevent injuries and treat them if they show up. The creation of structured diagnostic-therapeutic paths guarantees a better coordination of the professional figures involved, optimizes the management of the direct and indirect resources required to manage such a clinically challenging complication. After many years of activity we have built a solid integration between diabetologist and orthopedic, between hospital and territory and we have simplified a complex path. The fulcrum of this activity is the joint orthopaedic clinic that guarantees the correct care of the patient and allows the professional growth of the whole team.

Silver Mineralization

Information on the geological and isotopic age of the Kubaka gold-silver deposit in the Omolon middle massif in the North-East of Russia is presented. It has been established that the Kubaka deposit geological age lies in between the Late Devonian age of the Kedon series volcanites, containing the gold-silver mineralization, and the Early Carboniferous age of the Korbinsky suite terrigenous rocks, overlapping the volcanites and the mineralization. The post-ore nature of the Omolon complex dykes, which produce no significant impact on the distribution of gold mineralization in ore bodies, is shown. According to isotope dating, the following stages of the Kubaka deposit formation are distinguished: the accumulation of the Kubaka suite tuffs (369 Ma); the introduction of subvolcanic intrusions (344 and 337 Ma); the formation of ore metasomatites (335±5 Ma); the formation of gold-silver mineralization (330 and 334 - 324 Ma); the introduction of post-ore dikes (179±8 - 176±10 Ma).

The question of the geological age of the yellow sandstones of the district lying to the north of the city of Elgin has been, as is well known, the subject of very animated discussions among geologists. Some have even gone so far as to assert that the evidence on the question, which has been adduced by palaeontologists, is absolutely incapable of reconciliation with that relied upon by stratigraphists.

The liquid and plastic limits for a variety of natural and artificial soils covering a wide range of plasticity, as determined by the Casagrande method and the fall cone test and based on a strength criterion, were compared. To check the validity of the strength criterion, the undrained shear strength of these soils has been determined with a laboratory vane over the water content range between these limits. A limited comparison of the undrained strength values obtained from the vane test and fall cone test is also given. Key words: Atterberg limits, consistency, fall cone, laboratory vane, shear strength.

- This study is aimed at investigating outpatients' and clients' experience of communication with a group of employees of a hospital in the North of Italy. Participants in the study were 328 patients/users who were asked to report their communicative experience with 20 hospital employees using the Health Care Communication Questionnaire (HCCQ). Employees were 40% administrative, 60% ambulatory nurses and technicians, and 82% females. The comparison between employees on scores obtained showed significant differences in two of the four factors of the questionnaire (Lack of hostility and Non verbal immediacy). Furthermore, the female employees have been perceived by patients as less hostile then men. Female patients/users felt to be more respected then males, but this difference was linked to age, as among males the feeling of being respected decreased with age. Finally, it was possible to observe the scores obtained by each hospital employee in the HCCQ factors, to detect which of the four communicative behaviours has been evaluated by the users as less appropriate. This seems useful for planning personalized training.Key words: communication, patients, hospital personnel.Parole chiave: comunicazione, pazienti, personale ospedaliero
