Published: June 2023

CNC machines are computer-controlled machines that can understand the N and G codes (Gcodes) that regulate the machine tool system, (program motion pointers using numbers and letters to cut rotating workpieces), the machine works according to code commands. The code programme used is G75 for the groove making process and G97 for the CNC Turning process. The research aims to determine the variation of spindle rotation on S45C carbon steel. The speed variations used are 1266 rpm, 1066 rpm, 866 rpm. With a depth of cut of 0.4 mm and a feeding of cut of 0.15 mm and the insert used is an insert with the Iscar brand. The average value results obtained from the testing process using a roughness test tool (stylus). The lowest roughness value at 1266 rpm spindle rotation is included in the roughness class, namely N7. The highest roughness value at 866 rpm spindle rotation is included in the roughness class, namely N8. While the intermediate roughness value at 1066 rpm spindle rotation is included in the N7 roughness class. The effect of roughness results on objects, namely, the higher the spindle rotation, the lower the value of the roughness results, on the contrary, the lower the spindle rotation, the rougher the roughness value in the turning process.

PT XYZ is a subsidiary from one of the largest fertilizer companies in Indonesia which was only formed at the end of 2022 which was previously a compartment of its parent company. PT XYZ has several departments under it starting from the maintenance department, fabrication department, engineering and business department and also the ALBER (Heavy Equipment) department. Because it is a newly established company and with the addition of several new units, an OHS policy is needed for the safety of the company's work activities. Especially for the mobile crane units. The Hazard ldentification, Risk Assessment, and Risk ControI (HIRARC) procedure was apIicated in this study to minimaIized any kind of risk. Using the Job Safety AnaIysis (JSA) method at the Hazard ldentification stage in this study. The risks to the hazards that have been identified wiII be counted based on likeIihood and severity, which wiII determine the Ievel of risk. Based on the risk assessment, potential hazards are categorized into 4 levels, namely low risk, medium risk, high risk and extreme risk. In carrying out the mobile crane rental business process activities, 11 work activities with low and medium risk were found. What is highlighted in this business process is the process of operating a mobile crane where almost all activities carried out by operating a mobile crane have a risk with the highest severity value. Given the high risks that exist in the process of operating a mobile crane, updates and controls must be carried out frequently. Because if you not improve tooIs and work activity the danger will be increased. It is necessary to socialize the application of K3 policies regularly and continuousIy from the beginning to the end of the business process.

Quantitative analysis of the regulatory gene HSF1 of Bemisia tabaci under different temperatures
Authors: Лю Шунсяо , Ю Хао , Власенко В.А. 
Published: June 2023

Bemisia tabaci (Gennadius) is one of the most important pests in tropical, subtropical and adjacent temperate regions. B. tabaci is a major agricultural pest that is closely watched worldwide. With the widespread application of vegetable greenhouse planting patterns and frequent vegetable and flower transfers, more favorable conditions were created for the occurrence and spread of B. tabaci, making it the major pest in China's agricultural production.
The ability of B-biotype to adapt for new environments is closely related to its tolerance to temperature. Heat shock proteins (HSP s) are the group of proteins produced by cells under the induction of stressors, especially environmental high temperature. Heat shock proteins play an important role in the adaptability of organisms to the environment. This experiment mainly was studied from the heat shock protein of B. tabaci and its regulatory factors (Heat shock factor 1, hsf1). Meanwhile, fluorescence quantitative technology was used to observe the expression of this regulatory factor under different temperature conditions. It is speculated that the HSPs regulatory factor hsf1 is B-biotype B. tabaci and it can induce protection against high temperature stress.

Multi-decadal observations in the Alps reveal less and wetter snow, with increasing variability
Authors: Marty Christoph , Rohrer Mario B. , Huss Matthias , Stähli Manfred 
Published: June 2023

Snowpack is an important temporal water storage for downstream areas, a potential source of natural hazards (avalanches or floods) and a prerequisite for winter tourism. Here, we use thousands of manual measurements of the water equivalent of the snow cover (SWE) from almost 30 stations between 1,200 and 2,900 m a.s.l. from four long-term monitoring programs (earliest start in 1937) in the center of the European Alps to derive daily SWE based on snow depth data for each station. The inferred long-term daily SWE time series were analyzed regarding spatial differences, as well as potential temporal changes in variability and seasonal averages during the last 7 decades (1957–2022). The investigation based on important hydro-climatological SWE indicators demonstrates significant decreasing trends for mean SWE (Nov-Apr) and for maximum SWE, as well as a significantly earlier occurrence of the maximum SWE and earlier disappearance of the continuous snow cover. The anomalies of mean SWE revealed that the series of low-snow winters since the 1990s is unprecedented since the beginning of measurements. Increased melting during the accumulation period below 2000 m a.s.l is also observed–especially in the most recent years–as well as slower melt rates in spring, and higher day-to-day variability. For these trends no regional differences were found despite the climatological variability of the investigated stations. This indicates that the results are transferable to other regions of the Alps.

IntroductionFollowing total parathyroidectomy (PTx), transcervical thymectomy, and forearm autograft for secondary hyperparathyroidism (SHPT), recurrent SHPT can occur in the autografted forearm. However, few studies have investigated the factors contributing to re-PTx due to autograft-dependent recurrent SHPT before the completion of the initial PTx.MethodsA total of 770 patients who had autografted parathyroid fragments derived from only one of the resected parathyroid glands (PTGs) and who had undergone successful initial total PTx and transcervical thymectomy—defined by serum intact parathyroid hormone level &lt; 60 pg/mL on postoperative day 1—between January 2001 and December 2022 were included in this retrospective cohort study. Factors contributing to re-PTx due to graft-dependent recurrent SHPT before the completion of the initial PTx were investigated using multivariate Cox regression analysis. Receiver operating characteristic (ROC) curve analysis was performed to obtain the optimal maximum diameter of PTG for autograft.ResultsUnivariate analysis showed that dialysis vintage and maximum diameter and weight of the PTG for autograft were significant factors contributing to graft-dependent recurrent SHPT. However, multivariate analysis revealed that dialysis vintage (P=0.010; hazard ratio [HR], 0.995; 95% confidence interval [CI], 0.992–0.999) and the maximum diameter of the PTG for autograft (P=0.046; HR, 1.107; 95% CI, 1.002–1.224) significantly contributed to graft-dependent recurrent SHPT. ROC curve analysis showed that &lt; 14 mm was the optimal maximum diameter of PTG for autograft (area under the curve, 0.628; 95% CI, 0.551–0.705).ConclusionsThe dialysis vintage and maximum diameter of PTG for autograft may contribute to re-PTx due to autograft-dependent recurrent SHPT, which can be prevented by using PTGs with a maximum diameter of &lt; 14 mm for autograft.

Introduction:Unioniade is a species-rich family of freshwater mussels with an almost worldwide distribution. In Central European rivers Unio crassus, Unio tumidus and Unio pictorum have relatively high populations. In order to characterize the habitats of these suspension feeders, their nutrient supply and potential metal contaminants were investigated in near-bottom suspended (NBS) sediments and bottom sediments (BS) collected at four sampling locations along the Tisza River.Methods: The grain size distribution of sediments was determined by laser-diffraction technique. The total organic carbon (TOC) and the total Kjeldahl nitrogen (TN) were measured by a TOC analyzer and automated colorimetry, respectively. The phosphorous and metal concentrations were determined by inductively coupled plasma mass spectrometry following a microwave assisted acidic extraction of sediments with aqua regia.Results: The NBS sediments contained smaller grains than the BS samples, with roughly 85%–90% of the particles being less than 60 μm, allowing these mussels to catch them. Contrarily, only 2.47%–51.8% of BS samples were less than 60 μm. The NBS sediments contained 30, 23, and 15% more organic carbon, nitrogen, and phosphorous, respectively, than the BS samples. The rounded C:N:P molar ratios in the NBS sediments were 60:4:1, whereas they were 45:3:1 in the bottom sediments. The concentration of metals was also greater in the NBS sediments with the exception of Zn at Tokaj and Fe, Al, Mn, and Cr at Szeged, where prior contaminations transported by the tributaries Bodrog and Maros are stored in the top 10 cm of BS.Discussion: On basis of the measured C:N:P molar ratios it can be stated that soil-derived organic materials are the main sources of the nutrient elements in the habitats of suspension feeders in the Tisza River. The finer NBS sediments have higher specific surface area than the BS and thereby contain more biofilms on the grains resulting in higher proportion of organic nutrients and metal ions bounded as complexes or chelates. Comparing the measured metal concentrations of sediments with the concentration limits summarized in the Consensus-Based Sediment Quality Guidelines developed for evaluation of potential risk of metal contaminants in sediments for the benthic-dwelling organisms, it can be established that only the Hg concentration exceeded the probable effect concentration.

PurposeTo analyze the relationship between eccentric downward eye movement/eccentric downward eye-positioning (EDEM/EDEP) encountered in patients undergoing ophthalmic surgeries and its return to a centralized position under general anesthesia (GA) with the depth of anesthesia (DOA).MethodsPatients undergoing ophthalmic surgeries (6 months-12 years) under sevoflurane anesthesia without non-depolarizing muscle relaxant (NDMR) who witnessed a sudden tonic EDEM/EDEP were both retrospectively (R-group) and prospectively (P-group) enrolled (ambispective study). R-group included data-points after induction (AI) till the time surgery lasted while P-group compiled data both during induction (DI) and AI. DOA in terms of MAC (minimum alveolar concentration) at the time of EDEM/EDEP and centralization of eyeball and their timings were noted and compared for both AI and DI data-points. Also, vertical eccentric eye positions were scored and correlated with MAC.ResultsAI data included 22 (14R+8P) events and their mean MAC of EDEM/EDEP and centralization were 1.60 ± 0.25 and 1.18 ± 0.17 respectively (p = 0.000). DI data included 62 (P) cases and its mean MAC of EDEM/EDEP and centralization was 2.19 ± 0.43 and 1.39 ± 0.26 respectively (p = 0.000). Median (IQR) eye positions during down-positioning in 84 events was −3 (−3.9 to −2.5). It was preceded by an eccentric upward drift of eyes in 10/22 (6R+4P) AI cases. A strong negative correlation was seen between DOA and eccentric eye positions (r = −0.77, p = 0.000).ConclusionsTonic down-rolling of eyes is not uncommon in children seen without NDMR with higher depths of sevoflurane anesthesia compared to point of centralization and fluctuations in DOA should be avoided to circumvent inadvertent complications during ocular surgery.

Published: June 2023

BackgroundAn optimized anesthesia monitoring using electroencephalographic (EEG) information in the elderly could help to reduce the incidence of postoperative complications. Processed EEG information that is available to the anesthesiologist is affected by the age-induced changes of the raw EEG. While most of these methods indicate a “more awake” patient with age, the permutation entropy (PeEn) has been proposed as an age-independent measure. In this article, we show that PeEn is also influenced by age, independent of parameter settings.MethodsWe retrospectively analyzed the EEG of more than 300 patients, recorded during steady state anesthesia without stimulation, and calculated the PeEn for different embedding dimensions m that was applied to the EEG filtered to a wide variety of frequency ranges. We constructed linear models to evaluate the relationship between age and PeEn. To compare our results to published studies, we also performed a stepwise dichotomization and used non-parametric tests and effect sizes for pairwise comparisons.ResultsWe found a significant influence of age on PeEn for all settings except for narrow band EEG activity. The analysis of the dichotomized data also revealed significant differences between old and young patients for the PeEn settings used in published studies.ConclusionBased on our findings, we could show the influence of age on PeEn. This result was independent of parameter, sample rate, and filter settings. Hence, age should be taken into consideration when using PeEn to monitor patient EEG.

IntroductionThe rise of soft robotics has driven the development of devices for assistance in activities of daily living (ADL). Likewise, different types of actuation have been developed for safer human interaction. Recently, textile-based pneumatic actuation has been introduced in hand exoskeletons for features such as biocompatibility, flexibility, and durability. These devices have demonstrated their potential use in assisting ADLs, such as the degrees of freedom assisted, the force exerted, or the inclusion of sensors. However, performing ADLs requires the use of different objects, so exoskeletons must provide the ability to grasp and maintain stable contact with a variety of objects to lead to the successful development of ADLs. Although textile-based exoskeletons have demonstrated significant advancements, the ability of these devices to maintain stable contact with a variety of objects commonly used in ADLs has yet to be fully evaluated.Materials and methodsThis paper presents the development and experimental validation in healthy users of a fabric-based soft hand exoskeleton through a grasping performance test using The Anthropomorphic Hand Assessment Protocol (AHAP), which assesses eight types of grasping with 24 objects of different shapes, sizes, textures, weights, and rigidities, and two standardized tests used in the rehabilitation processes of post- stroke patients.Results and discussionA total of 10 healthy users (45.50 ± 14.93 years old) participated in this study. The results indicate that the device can assist in developing ADLs by evaluating the eight types of grasps of the AHAP. A score of 95.76 ± 2.90% out of 100% was obtained for the Maintaining Score, indicating that the ExHand Exoskeleton can maintain stable contact with various daily living objects. In addition, the results of the user satisfaction questionnaire indicated a positive mean score of 4.27 ± 0.34 on a Likert scale ranging from 1 to 5.
