Authors: Peng Zhenghao , Zhang Dongmei , He Ye , Ma Jiasheng , Li Yu , Yu Ruowen , Yuan Wantin , Xu Hong
Published: June 2024

In this study, a new method based on Kalman filter fusion algorithm is proposed for the key problem of temperature and humidity monitoring in locust breeding greenhouses. The traditional method has many limitations in processing temperature and humidity data, and is susceptible to sensor failure, environmental interference and other factors, resulting in monitoring results deviating from the actual situation. Especially in the locust farming environment, locust activities may have a large impact on the monitoring system. To solve the above problems, Kalman filter fusion algorithm is used in this study. Kalman filtering is a recursive state estimation algorithm, which continuously updates the state estimates by predicting the current state and correcting the observed values, so as to realize the accurate estimation of the system state. In this study, we utilize the Kalman filter algorithm to fuse the temperature and humidity data collected by multiple sensors, and at the same time, we consider the system dynamic model to dynamically adjust the degree of data fusion, which improves the accuracy and stability of the monitoring data. Finally, this study compares the Kalman filter fusion algorithm with the simple averaging method commonly used in ordinary agricultural greenhouses, and the results show that the Kalman filter fusion algorithm can obtain more accurate and smooth data.

Authors: Wan Chuanjie , Xiong Fuping , Zhang Kai
Published: June 2024

In this paper, the detection methods of heavy metals in human blood and urine were studied in detail. Firstly, we discussed the harm of heavy metal pollution, including its negative impact on human health, ecological environment and biodiversity. Heavy metal pollution may not only lead to various diseases, but also may cause damage to ecosystems and biodiversity. Next, we looked at the sources of heavy metals in human blood and urine. These heavy metals can enter the body through environmental exposure, food intake and biological transformation. For example, long-term exposure to polluted environments, or ingestion of food and water containing heavy metals, can cause heavy metals to accumulate in the human body. In addition, biotransformation may also convert some heavy metals from ingestion outside the body to accumulation in the body. Therefore, testing the amount of heavy metals in human blood and urine is of great significance for assessing health risks and environmental pollution.

Published: June 2024

The latest time for lactate measurement in patients with septic shock in the intensive care unit (ICU) is still controversial, and there is little mention of the significant impact of lactate levels on patient mortality. This study aims to use statistical methods to analyze and predict the prognosis of patients with septic shock using lactate measurement values. All data comes from the eICU collaborative research database. This study first used statistical methods to describe the baseline characteristics of patients. Then, the optimal judgment threshold for lactate measurement was determined using the Jordan index, and patients were divided into two groups based on the optimal threshold. Based on this, survival analysis was conducted using the Kaplan Meier curve and the binary values of lactate levels, while conducting a multivariate analysis. Finally, the relationship between the latest measurement time of lactate and outcome was found through smooth curve fitting. The main exposed factor is lactate measurement, and the main outcome is 28 days mortality. The study included 5776 eligible patients with septic shock, including 4920 surviving patients and 856 deceased patients. Observations have confirmed that patients with severe sepsis or septic shock whose lactate value exceeds 2.29 mmol/L after entering the ICU have an increased risk of death. At the same time, the latest lactate measurement time after entering the ICU is 0.42 days, which is about 10 hours before entering the ICU ward; otherwise, it will endanger the patient's life.

Authors: Balcanu Ruxandra
Published: June 2024

This paper brings an in-depth look on 20th-century built heritage by researching refurbishment opportunities for Romanian sports halls built during the communist regime. In those times, sports played a significant role for the controlling party's general propaganda machine. Being a leisure activity it infiltrated every aspect of society, from the worker’s everyday schedule to the newly constructed collective buildings.Sports halls were part of a larger and thoroughly controlled by the state urban equipment network spanning the entire country. After the fall of the communist regime, these buildings were left untouched and unused, as the sports phenomenon diminished in importance without the state’s constant implication. Even so, these buildings continue to impress evincing some innovative  features for that period, from braided steel cables to post- or pre-stressed concrete beams and prefabricated systems for the whole construction. The synergy between the structure and the architecture casts the unique monumental image of these buildings onto their surroundings.The research investigates the opportunity for refurbishment and reuse of these buildings as opposed to the demolition alternative. We will look in their future by comparing several case studies. Besides its historical approach, the study aims at bringing forward the communist recent built heritage issue.

Such aphenomenon is registered on the regional road R-1202 Mavrovo-Debar, in the western part of North Macedonia, where on one of the lanes on the side of the slope there is a subsidence of the road construction. In this paper measures for stabilisation and rehabilitation of the landslide on the regional road are presented. This particular terrain is characterised by steep slopes, and in addition to the terrain instability reasons stated above, there is an inadequate maintenance of the drains and canals that are a part of the road structure. Therefore, the problem has been studied and recommendations are given for stabilisation and rehabilitation measures. The proposal is to build a structure to relocate and strengthen the unstable zone consisting of a slab founded on piles that will transfer the load to the lower layers. For this purpose, two software programs are used: “Slide”, which analyses the stability by boundary equilibrium methods, and “Plaxis 2D”, which is used to calculate deformations and straining. According to the results obtained from “Slide”, the safety factor value Fs = 0.988 proves that the slope is not stable and there is a need for slope reinforcement, as well as rehabilitation of the road with reinforced concrete slabs and piles. While the design of the technical solution is simulated in several phases, according to the obtained results it is concluded that valid results are obtained from the last phase of exploitation and the maximum deformations Utot = 14.23 mm are shown and they occur in the pile capping beam. The horizontal and vertical displacements are 4.50 mm or 14.13 mm accordingly. Hence, the conclusion is that the steps taken for stabilisation and reconstruction of the landslide on the road Mavrovo - Debar meet the project-exploitation requirements.

Rural areas occupy more than a half territory of the Republic of Serbia, and they are home for more than 50% of total population. These areas are very diverse due to different topographic structure, settlements within them emerged mainly spontaneous - adjusting to the existing terrain. Settlements in rural areas have very vibrant history and the influence of different cultures left marks on their current structure. In Serbia, rural areas are characterized with low population density, inadequate access to main public services, lack of communal infrastructure, low income and mainly agriculture-oriented economy. One of the biggest problems that rural areas are facing is certainly unfavorable sociodemographic structure due to constant depopulation process and low quality of life.Starting from the assumption that rural population represents one of the biggest rural resources, this paper discusses possibilities and challenges for improvement of sociodemographic structure in rural areas in Serbia. Within this paper, first the current state of rural areas is analyzed and key development problems and possibilities are determined. Then, the examples of positive practice of implemented projects in rural areas in Europe are presented in order to illustrate possibilities for improvement of socio-demographic structure. Based on these findings, the aim of this paper is to propose possibilities for improvement of socio-demographic structure in rural areas. It is concluded that sociodemographic structure has influence on all other structures of rural areas and that its improvement is important for overall rural development.

The School Literacy Movement (GLS) is a government initiative aimed at fostering reading interest and literacy culture among students. One crucial element of literacy is writing ability, including poetry writing. This study aims to examine the impact of GLS on students' poetry writing skills. Literacy encompasses not only reading skills but also writing skills. Poetry writing is an important form of creative expression in literacy education. Poetry helps students develop language skills, enrich their vocabulary, and express their emotions and thoughts. This research aims to determine whether the school literacy movement can influence the poetry writing skills of students at SDN Kletekan 2. The approach in this study is quantitative, with a one-group pre-test post-test research design. The sample consists of all 15 fourth-grade students at SDN Kletekan 2. The prerequisite tests for the study include normality and homogeneity tests, where data is considered normally distributed if the significance value (sig) is > 0.05. The sample is considered homogeneous if the significance value (sig) is > 0.05. Prerequisite tests were conducted using the SPSS 24 application. This study employs hypothesis testing with a paired sample t-test. Data collection was conducted using test instruments. The results indicate that the school literacy movement activities have an impact on the poetry writing skills of fourth-grade students at SDN Kletekan 2, as shown by the paired sample t-test results with a significance value of 0.000 < 0.05. Thus, it can be concluded that the school literacy movement activities can influence the poetry writing skills of fourth-grade students at SDN Kletekan 2.
