For a long period of time, design and manufacturing technology of high flow rated vertically suspended pumps (VSPs) which have an extensive applications in many industries such as water and wastewater, mining, petrochemical and oil and gas industries, used to be imported from European countries. For the first time in Iran's pump industry, with the support of Ministry of Petrochemical[ah1]  and ...

New data mining tools and algorithms are available for vertical data mining communities for scalable and efficient data mining to discover the hidden nuggets from huge repositories of data. Most of the traditional data mining algorithms do not scale on these huge datasets. This is due to insufficient computational resources, currently available on a single machine for running these applications...

Preparation and in vitro and in vivo evaluation of vinpocetine (VIN) elementary osmotic pump (EOP) formulations were investigated. A method for the preparation of VIN elementary osmotic pump tablet was obtained by adding organic acid additives to increase VIN solubility. VIN was used as the active pharmaceutical ingredient, lactose and mannitol as osmotic agent. Citric acid was used as increasi...

Vertical profiles of suspended particulate trace metals were measured in the Sargasso Sea near Bermuda and in the California Current, northwest Pacific. Using a new in situ pump, sufficiently large samples of particulate matter (order 10mg) were collected to allow measurement of a suite of trace metals as well as major component elements, using several different leaching techniques on separate ...

Penelitian ini bertujuan membuat alat deteksi kebocoran gas LPG serta penanggulangannya jika terjadi kebakaran. Pada pengoperasianya akan dibantu oleh Node MCU ESP8266 sebagai perangkat mikrokontroler untuk menjalankan berbagai macam perintah. Adaptor DC 12V penyedia sumber tenaga listrik dan adaptor 5V digunakan menghidupkan kipas water pump. Sensor MQ2 memiliki nilai presentase error rata-rat...

Vertical turbine pumps are designed to operate with the pump shafts in tension (downthrust). Most pump and motor manufacturers caution users to not operate the vertical turbine pumps at conditions that result in “upthrust.” Upthrust conditions are usually encountered for a few seconds each time the pump is started; however, the pump should not be operated for periods longer than a few seconds i...

The paper suggests a stationary model of the vertical distribution of the concentration of suspended sediment in the bottom layer of a natural water body with a flat bottom. The model explains the concentration distribution, formed jointly by the settling of suspended particles and turbulent diffusion. The flow is assumed geostrophic above the bottom-influenced layer, while in the bottom layer ...
