Typical experiments in psychological and neurophysiological settings often require the accurate control of multiple input and output signals. These signals are often generated or recorded via computer software and/or external dedicated hardware. Dedicated hardware is usually very expensive and requires additional software to control its behavior. In the present article, I present some accuracy tests on a low-cost and open-source I/O board (Arduino family) that may be useful in many lab environments. One of the strengths of Arduinos is the possibility they afford to load the experimental script on the board’s memory and let it run without interfacing with computers or external software, thus granting complete independence, portability, and accuracy. Furthermore, a large community has arisen around the Arduino idea and offers many hardware add-ons and hundreds of free scripts for different projects. Accuracy tests show that Arduino boards may be an inexpensive tool for many psychological and neurophysiological labs.

We review the current state of quality assurance in laboratories of the five Central Asia Republics (CARs), focusing on laboratory equipment, and compare quality assurance approaches with CLSI standards. The laboratories of the CARs faced exceptional challenges including highly-structured laboratory systems that retain centralized and outmoded Soviet-era approaches to quality assurance, considerably jeopardizing the validity of laboratory tests. The relative isolation of the CARs, based on geography and almost exclusive use of the Russian language, further hamper change. CARs must make high-level government decisions to widely implement quality assurance programs within their laboratory systems, within which approaches to the management of laboratory equipment will be a prominent part.

Personalized exoskeleton assistance provides users with the largest improvements in walking speed 1 and energy economy 2 – 4 but requires lengthy tests under unnatural laboratory conditions. Here we show that exoskeleton optimization can be performed rapidly and under real-world conditions. We designed a portable ankle exoskeleton based on insights from tests with a versatile laboratory testbed. We developed a data-driven method for optimizing exoskeleton assistance outdoors using wearable sensors and found that it was equally effective as laboratory methods, but identified optimal parameters four times faster. We performed real-world optimization using data collected during many short bouts of walking at varying speeds. Assistance optimized during one hour of naturalistic walking in a public setting increased self-selected speed by 9 ± 4% and reduced the energy used to travel a given distance by 17 ± 5% compared with normal shoes. This assistance reduced metabolic energy consumption by 23 ± 8% when participants walked on a treadmill at a standard speed of 1.5 m s −1 . Human movements encode information that can be used to personalize assistive devices and enhance performance. A portable ankle exoskeleton uses a data-driven method and wearable sensors to adapt to the user as they walk in a natural setting.

Isolation of human peripheral blood mononuclear cells (PBMCs) from blood typically involves a density gradient medium during density centrifugation. The problem of increasing red blood cell (RBC) and granulocyte (GRA) contamination during PBMC isolation as the elapsed time after blood collection increases remains unresolved. As a countermeasure against RBC contamination, hemolysis treatment is available; however, these extra steps are laborious, time-consuming, and could introduce artifacts. To overcome this challenge, we developed a novel isolation device, FlowMagic[TM], which features a proprietary two-layer insert structure designed to prevent RBC and GRA contamination during PBMC isolation from blood. The efficacy of this method was evaluated by isolating PBMCs from donors and analyzing immune cell populations by flow cytometry. Compared to SepMate (median (Q50) = 11.0, interquartile ranges (IQR): 8.8-19.5; p < 0.01) and Lymphoprep methods (Q50 = 9.3, IQR: 6.6-13.5; p < 0.01), FlowMagic[TM] achieved significantly greater reduction in RBC contamination to below detectable limits (Q50 = 0.0, IQR: 0.0-0.0), with sustained efficacy observed up to 72 hours post-collection. Additionally, the FlowMagic[TM] method (Q50 = 2.5, IQR: 0.5-3.4, at 48 hours, median = 4.5, IQR: 2.1-10.3, at 72 hours, respectively) significantly reduced GRA contamination compared with the SepMate (Q50 = 12.0, IQR: 7.8-25.5, at 48 hours, Q50 = 27.5, IQR: 12.3-29.0, at 72 hours, respectively; p < 0.01) and Lymphoprep methods (Q50 = 10.5, IQR: 6.9-19.8, at 48 hours, Q50 = 17.5, IQR: 13.3-23.5, at 72 hours, respectively; p < 0.01) at 48 and 72 hours after blood collection. Furthermore, the recovery rates of CD3 +, CD4 +, CD8 +, CD19 +, and CD16/56 + cells in the FlowMagic[TM]-isolated PBMCs (Q50 = 8.6, 5.9, 2.5, 1.3, and 1.9, respectively) were significantly improved compared to those in SepMate- (Q50 = 2.2, 1.5, 0.7, 0.4, and 0.5, respectively; p < 0.01) and Lymphoprep-isolated PBMCs (Q50 = 2.4, 1.5, 0.8, 0.6, and 0.8, respectively; p < 0.01), even at 48 hours after blood collection. These findings suggest that the PBMC isolation method using FlowMagic[TM] is advantageous in preventing RBC and GRA contamination for research, diagnostic, and clinical applications.

PT Promedika Sejahtera is a company engaged in the laboratory equipment industry, that need its strategic touch on its Strategic Laboratory Equipment. Products sold by the company are Oxygen, Medical Equipment, Ultraviolet System, Activated Carbon Filter, Pempers, and Underpad. Products that exist in the company are not in their own production in the production from abroad. PT Promedika Sejahtera merely sell the laboratory equipment. Yet, the company has various types of consumers namely hospitals, hospital cooperatives, pharmacies, factories, and water equipment RO shops. In this paper, strategic laboratory equipment industry refers specifically to inventory within the supply chain management perspectives. This paper constitutes collaboration with other papers on Economic Order Quantity (EOQ), Re-Order Point (ROP), and Safety Stock (SS), that convolutes Forecasting, ABC Analysis, and Partial Least Square (PLS). Yet, this paper refers to its focus merely on Forecasting, Demand Pattern, Exponential Smoothing and EOQ. As part of conclusion, this paper conveys several highlighted remarks. Those remarks refer to ABC Analysis. The grouping of goods using ABC Analysis Method is divided into three groups: A with 80% priority, group B with 20% priority and group C with 10% priority. The number of goods in group A is 12 items, group B 18 item type and group C are 30 items of goods. Forecasting demand required by the Company for 2018 based on priority group A can be done using the Double Exponential Smoothing (Holt's) Method because the pattern pattern possessed from the previous year's sales data has no seasonal but has a random trend. The results of these calculations can be seen from the table of existing research results. Ultimately, Future research is deemed indispensable within novelty purpose for the industrial system sustainability within Strategic Laboratory Equipment Industry.

The presented article deals with the design of equipment for measuring and testing hydrostatic transducers. The presented design of the device is used for measuring and testing hydrostatic transducers in laboratory conditions, especially hydraulic pumps. This shortens the testing time, with a reduction in economic costs for testing the elements of the hydraulic circuit or testing the properties of pumps and hydraulic fluids. By simulating the operating conditions occurring in practice, it is possible to verify and evaluate the parameters of mobile energy means used in hydraulic mechanisms. The designed laboratory equipment is used for measuring and testing hydrostatic transducers and properties of hydraulic fluids. A verification measurement of the flow of the hydrostatic transducer was performed on the proposed laboratory equipment. The output of the measurements is a confirmation of the functionality of the designed equipment. The results of the verification measurement were compared with the data obtained during the simulations in the computer program FluidSIM 5. The output of the measurements is a confirmation of the functionality of the designed equipment. When comparing the results of the verification measurement of the flow on the laboratory equipment with the data given by the manufacturer of the transducer, we recorded a decrease in flow of 5.1% at a speed of 250 rpm in comparison. At 500 rpm we recorded an increase in flow of 2.38% and at 750 rpm there was an increase of 4.15% compared to the data from the manufacturer. The results of the verification measurements were also compared with the simulation in the computer program FluidSIM 5. The flow data obtained by the simulation showed higher values than in the verification measurement. Specifically, at 250 rpm it was an increase of 3.21%, at 500 rpm by 0.39%, and at 750 rpm by 3.14%.

The early diagnosis of infectious diseases is critical because it can greatly increase recovery rates and prevent the spread of diseases such as COVID-19; however, in many areas with insufficient medical facilities, the timely detection of diseases is challenging. Conventional medical testing methods require specialized laboratory equipment and well-trained operators, limiting the applicability of these tests. Microfluidic point-of-care (POC) equipment can rapidly detect diseases at low cost. This technology could be used to detect diseases in underdeveloped areas to reduce the effects of disease and improve quality of life in these areas. This review details microfluidic POC equipment and its applications. First, the concept of microfluidic POC devices is discussed. We then describe applications of microfluidic POC devices for infectious diseases, cardiovascular diseases, tumors (cancer), and chronic diseases, and discuss the future incorporation of microfluidic POC devices into applications such as wearable devices and telemedicine. Finally, the review concludes by analyzing the present state of the microfluidic field, and suggestions are made. This review is intended to call attention to the status of disease treatment in underdeveloped areas and to encourage the researchers of microfluidics to develop standards for these devices.

We describe a new version of the Chicago Water Isotope Spectrometer (ChiWIS), designed for airborne measurements of vapor-phase water isotopologues in the dry upper troposphere and lower stratosphere (UTLS) aboard research aircraft. This version of the instrument is a tunable diode laser (TDL), off-axis integrated cavity output spectrometer (OA-ICOS). The instrument was designed to measure the HDO / H.sub.2 O ratio in the 2017 Asian Summer Monsoon flight aboard the M-55 Geophysica during the StratoClim campaign, and so far has also flown aboard the WB-57F in the 2021 and 2022 ACCLIP campaigns. The spectrometer scans absorption lines of both H.sub.2 O and HDO near 2.647 µm wavelength in a single current sweep, and has an effective path length of 7.5 km under optimal conditions. The instrument utilizes a novel non-axially-symmetric optical component which increases the signal-to-noise ratio by a factor of 3. Ultra-polished, 4 in. (101.6 mm) diameter cavity mirrors suppress scattering losses, maximize mirror reflectivity, and yield optical fringing significantly below typical electrical noise levels. In laboratory conditions, the instrument has demonstrated a 5 s measurement precision of 3.6 ppbv and 82 pptv in H.sub.2 O and HDO, respectively.
