GCL-LLDPE geomembrane interface friction angle evaluation and stability analysis of a valley fill leach pad project

The Los Chancas mining project, initiated in 1998, is a copper mine focused on extracting copper sulfides and oxides. In 2020, a mine plan update required a review of the constructability design and an evaluation of the Permanent Leach Pad and Filtered Waste/Rock Dump's physical stability. This paper presents results from an evaluation study regarding friction angles at the liner interface and stability analysis in the VLF pad. Previously, an internal friction angle of 23° was established for the basal liner interface (LLDPE-GCL) to meet stability requirements. However, due to the high required friction angle, the pad design was updated with lower slopes. The study evaluated various GCL materials from two suppliers using direct shear tests, revealing that the GCL from the second supplier achieved a high friction angle of 22.3° at the interface. Stability analysis considered two critical sections, examining three types of failure under both static and pseudo-static conditions. Results showed a need for a minimum friction angle of 16° in static conditions and 20.5° in pseudo-static conditions to ensure compliance. These results suggest the potential use of high strength geosynthetic materials in the studied areas, with a preference for the GCL material offering the highest friction angle.

PH Measuring Pad for Underpad

Measuring the pH is very important to reveal the possible health problem risks of pets with early diagnosis, to enhance their quality of life and prevent negative effects on their health. However, measuring the pH level of cats and dogs urine’s is very painful and stressful process,especially during their birth duration. Accordingly, to support parents and veterinarians in this urine collection process, ‘pH Measuring pad for underpad’ project is studied. Using this ped will be quick, painless and guiding method.
 In addtion to these, environmental pollution which is known by all over the world is increasing. In order to prevent this pollution, several projects has been studied in this issue and also, all raw materials have been selected as be bio-based. In this newly studies under pad project, when animal health is considered, raw materials selection is made on the basis of protecting the nature. The product which contains special indicator emphasizes the innovative aspect of the project by perforemin health checks for pets. The raw materials which use in this project is selected from having higher mechanical properties ones and also, their processability is evaluated. Formulation is obtained by mixing suitable raw materials in certain proportions. 
 First of all, there is a print on top of this pad. This print is made with a bio ink which includes pH indicator. By means of this ink, after the pets leave their urine on the pad, observing of color change can be possible according to the urine’s pH level. Ideally, urine’s pH value should be aroud 6.5 for cats and dogs as be considere a healthy level. IF the pH is acisic (below 5.5/6) or alkaline (above 7/7.5), there may be bacteria, crystals, an imbalnce in blood values or a sign of illness, which can have a nagative impact on pet’s health. In addtion to this, the carrier breathable film which is used in the desing of the ‘pH measuring pad for underpad’ is produced with using low density polyethylene (LDPE) obtained from renewable resoruces (green). The non-woven fabric is produced from soybean protein fibers. While, These fibers are biodegradable, soybean protein fiber or SPF, is the only renewable botanical protein fiber that can be touch today. SPF is a unique active fiber. Also it contains 16 amino acids that are healty and nourishing for the skin.

Local innovation for improving primary care cardiology in resource-limited African settings: an insight on the Cardio Pad(®) project in Cameroon.

Cardiovascular disease (CVD) is an emerging threat to the health of populations in Africa. With the inadequate health infrastructures, understaffed and underfunded health systems, African countries are ill-prepared to cope with the increasing demand for care for CVD, particularly for populations in remote and underserved rural areas, where 60% of the population currently reside. Task shifting and telehealth have been suggested as strategies to overcome the current health workforce shortage in African countries, and to increase access to prevention and curative services for emerging CVD. However, strategies for promoting their incorporation into the existing health systems, have yet to be developed. The Cardio Pad(®) initiative (originating from Cameroon) seeks to provide appropriate solutions to improve the application of telemedicine for CVD prevention and control in remote African settings. The Cardio Pad(®) is a tele-cardiology device which provides a number of advantages in terms of cost, ease of use, autonomy and reduced technology requirements. It is a fully touch screen medical device which enables cardiac tests such as electrocardiograms (ECG) to be performed in remote underserved areas (rural areas for instance), while the test results are transferred wirelessly via mobile phone connection, to specialist physicians who can interpret them and provide assistance with case management. While most of the current telemedicine clinical services on the African continent receive most expertise from developed countries, the Cardio Pad(®), a local invention by a 26-year-old Cameroon-trained engineer demonstrates how much innovative solutions to combat CVD and other health issues could and should be developed locally in Africa.

The PEN & PAD Medical Record Model: Development of a Nursing Record for Hospital-based Care of the Elderly

The PEN & PAD Medical Record model describes a framework for an information model, designed to meet the requirements of an electronic medical record. This model has been successfully tested in a computer-based record system for General Practitioners as part of the PEN & PAD (GP) Project. Experiences of using the model for developing computer-based nursing records are reported. Results show that there are some problems with directly applying the model to the nursing domain. Whilst the main purpose of the nursing record is to document and communicate a patient's care, it has several other, possibly incompatible, roles. Furthermore, the structure and content of the information contained within the nursing record is heavily influenced by the need for the nursing profession to visibly demonstrate the philosophical frameworks underlying their work. By providing new insights into the professional background of nursing records, this work had highlighted the need for nurses to clarify and make explicit their uses of information, and also provided them with some tools to assist in this task.

Launch Pad project

I was pleased to see the report of the Science Museum's Launch Pad project (Physics Bulletin June 1985 p237). I am afraid, however, that there is a mistake about the funding of the project.

Electrophysiological study of the topography of the vibrissae projections to the tactile thalamus and cerebral cortex in mutant mice with hair defects

Projections of the mystacial vibrissae to the tactile thalamus and somatosensory neocortex were studied in mutant mice with hair defects, of the Mottled ( Mo Mo ), Hairless ( hr hr ), and Nude ( Nu Nu ) types. Results show that Mottled mice have projections of the same kind as normal mice. In Hairless mice there are silent zones between the projections of intact vibrissae. In Nude mice which lack hairs since birth, the most important change is that the vibrissae project to regions of the thalamus and the SI cerebral cortex ordinarily innervated from the common fur of the muzzle. Thus Nude mice seem to compensate for the absence of hairs of the common fur. We hypothesize that this change represents the counterpart of changes observed in normal mice whose vibrissae follicles were destroyed at birth. Nude mice lack hairs since birth and their vibrissae project to the fur regions. In normal mice whose vibrissae were destroyed at birth, common hairs of the mystacial pad project to the vibrissa region.

Receptive fields of barrels in the somatosensory neocortex of the rat.

Peripheral receptive fields of "barrels" in the somatosensory neocortex (SmI) of rats were determined with microelectrope recording and anatomical techniques. A method of flattening each hemisphere prior to embedding was devised so that the organization of layer IV could be seen through the full extent of SmI on a single section. All of the barrels in the rat are located within layer IV of Smi. sinus hairs on the lateral and rostral face and furry buccal pad project to a continuous sheet of barrels in the head area of the contralateral SmI. The pattern of projections in this area indicates that each barrel receives information from one sinus hair. Large whisking vibrissae project to the largest cell-dense barrels and smaller non-whisking sinus hairs project to smaller barrels that are relatively cell-sparse. Barrels were also found outside of the head area in regions that receive projections from the forepaw and hindfoot. Receptive fields of these barrels are located on glabrous and hairy surfaces of the appendages that do not include any sinus hairs. Other parts of the body project to cell-dense areas of SmI that do not appear to contain barrels. Barrel subgroups and other somatotopic areas are separated by narrow barrel-free zones. As a result of this pattern of contrasting cell densities, an outline of the rat's body is delineated within layer IV.
