Enhanced continuous atmospheric water harvesting with scalable hygroscopic gel driven by natural sunlight and wind

Sorption-based atmospheric water harvesting (SAWH) has received unprecedented attention as a future water and energy platform. However, the water productivity of SAWH systems is still constrained by the slow sorption kinetics at material and component levels and inefficient condensation. Here, we report a facile method to prepare hygroscopic interconnected porous gel (HIPG) with fast sorption-desorption kinetics, high scalability and stability, and strong adhesion property for highly efficient SAWH. We further design a solar-wind coupling driven SAWH device with collaborative heat and mass enhancement achieving continuous water production. Concentrated sunlight contributes to enhancing the desorption and condensation synergistically, and natural wind is introduced to drive the device operation and improve the sorption kinetics. The device demonstrated record high working performance of 14.9 Lwater m−2 day−1 and thermal efficiency of 25.7% in indoor experiments and 3.5–8.9 Lwater m−2 day−1 in outdoor experiments by solar concentration without any other energy consumption. This work provides an up-and-coming pathway to realize highly efficient and sustainable clean water supply for off-grid and arid regions.

Sistem Informasi Penilaian Prestasi Kerja Pegawai dengan Metode Pengembang Perangkat Lunak Model Waterfall

Providing an assessment of employee work performance is a method for evaluating their competence with the aim of development to produce competitive employees. A Civil Servant (PNS) who achieves good (high) work performance should get a reward (compensation) that is comparable. It aims to motivate and reward civil servants for improving performance. However, some opportunities can turn into threats if they are not anticipated, such as negative responses from the public if the government is unable to improve the quality of its employees' performance. Inaccurate and ineffective assessments can cause the process of assessing the performance and quality of State Civil Apparatus (ASN) to be inaccurate and inappropriate. Therefore, an assessment system is needed that is relevant, practical, reliable and acceptable so that the assessment results are more accurate good and useful for employees and personnel administration at the Pontianak Fisheries Training and Extension Center (BP3). This system refers to the Waterfall model, where the progress of a process is considered to flow continuously like a waterfall. In the waterfall model, each step must be sequential and you cannot proceed to the next step but must complete the first step then proceed to the second step, and so on. With the system that has been built, the employee performance appraisal process can be well-documented and more transparent. The results of testing using the black box testing method showed that the system functionality could meet all the expected requirement specifications.

Lighting and thermal factors on human comfort, work performance, and sick building syndrome in the underground building environment

The development of underground space can help cities solve problems such as the unmet demand for land and space. However, there are still many problems to be solved. The comfort of lighting and thermal environment, high work performance, and low prevalence of SBS symptoms play irreplaceable roles in creating a good indoor environment. The main purpose of this study is to investigate the differences in the comfort of lighting and thermal environment, work performance, and SBS symptoms among people living in underground spaces for long and short periods, and to provide optimal temperature and illuminance ranges for balancing these three aspects. A summer survey was conducted in subway stations, including measurements of environmental and physiological parameters, and psychological responses. A total of 952 questionnaires were collected for data analysis. The results show that the comfort of lighting and thermal environment for short-stay occupants is more sensitive to changes in indoor air temperature and illuminance. Reduction of indoor air temperature can improve occupants’ work performance and can reduce SBS symptoms. The optimal temperatures for long-stay and short-stay occupants are 25.6–26.3 °C and 24.5–24.8 °C (or 24.5–25.1 °C), respectively. The optimal illuminance ranges for long-stay and short-stay occupants are > 300.0 lx and > 494.0 lx, respectively. The results of this research contribute to the creation of healthy, comfortable, and beneficial indoor environments in shared underground building spaces.

Probe type optical fiber DNA hybridization biosensor based on polyethylenimine and Poly-L-Lysine surface functionalization method

Nucleotide hybridization technology is an effective method for achieving optical-based selective recognition of nucleotides. Unfortunately, the optimal work performance is always restricted by the lack of the coupling method used to bind sensors with nucleotide sequences. In this work, a series of nucleotide hybridization detection experiments based on optical fiber surface plasmon resonance (SPR) are conducted, aimed at comparing the ability to bind nucleotide of Polyethylenimine (PEI) and Poly-L-Lysine (PLL), which are common coupling agents in optical-based nucleotide hybridization study. In our work, qualitative nucleotide measurements using PEI and PLL are carried out in positive order, negative order, and temperature fluctuation, and confirm PEI has a higher work performance in nucleotide-binding and nucleotide-detection. Quantitative determination in the concentration range of 0–100 nmol/L demonstrates the DNA sensitivity reaches 0.13 nm/(nmol/L) and the detection limit (DL) lies in 4.9 nmol/L, which is outstanding compared with similar optical sensors. In this paper, two kinds of nucleotide molecule detection methods based on optical fiber SPR sensing technology with PEI and PLL are proposed and experimentally verified, and the nucleotide-binding capability of PLL and PEI is contrast analyzed according to experimental results for the first time. This study is of great significance for improving the measurement scheme of DNA sensors and the selection of gene carriers for manufacturing DNA complexes.

DLB: A Dynamic Load Balance Strategy for Distributed Training of Deep Neural Networks

Synchronous strategies with data parallelism are widely utilized in distributed training of Deep Neural Networks (DNNs), largely owing to their easy implementation yet promising performance. In these strategies, the workers with different computational capabilities need to wait for each other because of the essential gradient or weight synchronization. This will inevitably cause the high-performance workers to waste time waiting for the weak computational workers, which in turn results in the inefficiency of the cluster. In this paper, we propose a Dynamic Load Balance (DLB) strategy for the distributed training of DNNs to tackle this issue. Specifically, the performance of each worker is evaluated first based on the performance demonstration during the previous training epochs, and then the batch size and dataset partition are adaptively adjusted in consideration of the current performance of the workers. As a result, the waiting cost among the workers will be eliminated, thereby the utilization of the clusters is highly improved. Furthermore, the essential theoretical analysis has also been provided to justify the convergence of the proposed algorithm. Extensive experiments have been conducted on the CIFAR10 and CIFAR100 benchmark datasets with four state-of-the-art DNN models. The experimental results indicate that the proposed algorithm can significantly improve the utilization of the distributed cluster. In addition, the proposed algorithm can also prevent the load imbalance of the distributed DNN training from being affected by the disturbance and can be employed flexibly in conjunction with the other synchronous distributed DNN training methods.

Technological process of field crops spraying with slotted sprayers

BACKGROUND: The subject of the study is the technological process of spraying field crops with slotted sprayers and the indicators dispersion.
 AIMS: Improving the technological process of spraying plants with the use of pneumo-hydraulic slotted sprayers.
 METHODS: Special equipment was used for photographing films of the liquid being sprayed under various operating modes of slotted sprayers with the possibility of calculating the size of the droplets. Fulfillment of the requirements for the number of drops/cm2 at the treated object, overlapping the liquid spray jets ensures uniform distribution of drops over the spraying width. Therefore, it was sufficient to have information about the fragmentation of the thickness of the liquid film along the axis of the nozzle spray liquid into drops and obtaining their quantity per unit time depending on the flow rate of the working fluid.
 Newness of the research lies in determining the effective operation of slotted sprayers as part of the spraying device.
 RESULTS: With the use of the special equipment, it is possible to fulfill agrotechnical requirements for droplet sizes. When using herbicides for foliar post-emergence treatment with a systemic pesticide, the limits of MMD range are from 226 m to 400 m. Soil herbicide treatment with a systemic pesticide requires an increased droplet MMD range of 401 m to 500 m and 500 m. The number of drops/cm2 when using fungicides is limited from 50 to 70, insecticides from 20 to 30, and herbicides from 20 to 40.
 CONCLUSIONS: The applied technology makes it possible to reduce the consumption of preparations and working fluid with high work performance and resource saving. The above research results can be used as the basis for determining the effective technology of a boom sprayer with slotted liquid sprayers. Fulfillment of the requirements for the number of drops/cm2 at the treatment facility overlapping liquid spray torches ensures a uniform distribution of drops over the spraying width. Therefore, it suffices to know about the division of the thickness of the liquid film along the axis of the liquid spray jet into drops and to obtain their number per unit time.

Efficient and Robust Molecular Solar Thermal Fabric for Personal Thermal Management.

Molecular solar thermal (MOST) materials, which can efficiently capture solar energy and release it as heat on demand, are promising candidates for future personal thermal management (PTM) applications, preferably in the form of fabrics. However, developing MOST fabrics with high energy-storage capacity and stable working performance remains a significant challenge because of the low energy density of the molecular materials and their leakage from the fabric. Here, an efficient and robust MOST fabric for PTM using azopyrazole-containing microcapsules with a deep-UV-filter shell is reported. The MOST fabric, which can co-harvest solar and thermal energy, achieves efficient photocharging and photo-discharging (>90% photoconversion), a high energy density of 2.5kJm-2 , and long-term storage sustainability at month scale. Moreover, it can undergo multiple cycles of washing, rubbing, and recharging without significant loss of energy-storage capacity. This MOST microcapsule strategy is easily used for the scalable production of a MOST fabric for solar thermal moxibustion. This achievement offers a promising route for the application of wearable MOST materials with high energy-storage performance and robustness in PTM.
