Reducing the contour error of leading and trailing edge through feedrate scheduling in 5-axis machining of blisk
Authors: Wang Zhiwei , Lin Xiaojun , Shan Chenwei , Tian Heng 
Published: February 2024

Abstract

The blisks are complex thin-walled parts with specific structures that have narrow channels and a large degree of bowed-twisted blades. These parts are typically machined using 5-axis machining. However, conventional feedrate scheduling of the tool tip can cause flutter and reduced machining accuracy when dealing with very small radii of curvature and dramatic changes in the tool axis vector. This is because there is a significant difference in moving speed between the tool tip and cutting contact points. To address this issue, we establish an optimization model for feedrate under constraints such as process-allowed cutting speed and machine tool drive along the tool path. For sections of short tool paths in the regions of leading and trailing edges with drastic changes in curvature and tool orientations, we schedule a constant feedrate for the tool contact point. For other sections of the tool path, we construct time-optimal acceleration and deceleration velocity curves using parallel computing technology, ensuring no abrupt changes in acceleration or acceleration velocity at boundary points. Additionally, we smooth the feedrate profile curves for the entire toolpath using the parallel bidirectional scanning method. This approach improves both the efficiency of feedrate scheduling and cutting stability within the regions corresponding to the leading and trailing edges of blisks.

Abstract

In recent decades, the annual mean temperature has increased, with unusual alternations of hot and cold years. In addition, the changes in temporal precipitation patterns are caused by complex interactions between temperature change, the global water cycle, and other components of the Earth's systems. To construct a statistical model of these temporal patterns in terms of temperature and precipitation, we propose a logistic mixture of spatial multivariate penalized regression splines for temporal profiles and apply this model to the contiguous United States climate data over 123 years (1900 to 2022) at 252 weather stations. The results reveal that the proposed model identifies climatologically meaningful clusters of weather stations in the contiguous United States with two important meteorological variables, temperature and precipitation, identifying the climate change patterns of each climate zone. The surface air temperature increased in the Northeast and West (Mountain and Pacific) regions, where the climate is affected by the continental Arctic air. A notable increment of precipitation also occurred in the Northeast. In contrast, the South region, where the climate is affected by the tropical Atlantic Ocean, is more stable than other regions in terms of year-to-year variations in temperature and precipitation.

Authors: Lindén Magnus , Rosenblad Therese , Rosenborg Karin , Hansson Sverker , Brandström Per 
Published: February 2024

Abstract

Background:
Urinary tract infection (UTI) in infants is a common, potentially life-threatening bacterial infection, and must be managed carefully through the entire chain of care from diagnosis, choice of treatment, follow-up and risk stratification of future complications. This Swedish nationwide study of infant UTI was conducted to evaluate the current management of infant UTI, yield of investigations and the Swedish UTI guidelines’ ability to detect abnormalities of importance in the urinary tract.
Methods
Infants < 1 year with a first episode of UTI were included in a prospective multicenter study. Treatment and follow-up were provided by local pediatricians. Clinical and laboratory findings and imaging results were reported to the coordinating center. The current management and results were compared with a previous Swedish study.
Results
1306 infants were included. Urine sampling was performed with clean catch technique in 93% of patients. Initial oral antibiotic treatment was used in 63%, predominantly third generation cephalosporines. Permanent kidney abnormalities were found in 10% and dilating vesicoureteral reflux (VUR) in 8%, both representing minimum rates as not all infants were investigated. UTI recurrences were reported in 18%.
Conclusion
Infant UTI is still generating a considerable amount of follow-up examinations. There is a significant shift towards clean catch as the main urine sampling method. Voiding cystourethrography is performed less frequently reducing the findings of low grade VUR. The incidence of renal scarring is comparable with earlier studies which suggests that the Swedish guidelines are able to identify individuals with risk for long term complications.
Cultivating Tomorrow: A Comprehensive Review of Agricultural Innovations in the Philippines (2018-2023)
Authors: Taer Albino , Taer Erma 
Published: February 2024

Abstract
This systematic review undertook an examination of agricultural innovations in the Philippines spanning from 2018 to 2023. The objective was to provide a comprehensive categorization, analyze adoption trends, and offer recommendations to optimize research priorities. A methodical approach involving literature search, screening, and quantitative analysis facilitated an organized investigation into various innovation types, contributors, applications, and geographical contexts. The findings indicated that image analysis and sustainable farming systems held the highest shares within the innovation categories, comprising 26% and 23%, respectively. These segments showcased cutting-edge techniques along with a commitment to environmental stewardship. Notably, rice-centric innovations dominated at 33.33%, underscoring the underrepresentation of high-value crops, livestock, and remote farming sectors. However, a geographical bias was evident, with 69.23% of studies concentrating solely on Luzon regions, particularly in central and northern areas. This revealed a need to acknowledge the agricultural potential present in Visayas and Mindanao, emphasizing the necessity for increased research emphasis in these regions. Furthermore, the study unveiled a fragmented landscape in research contributions, with the majority of contributors representing less than a 5% share each. This fragmentation suggests a lack of cross-institutional partnerships, hindering a holistic and collaborative approach to agricultural innovation. Critical gaps in innovation prioritization and adoption levels were identified, particularly in sustainable practices, precision technologies, non-cereal commodities, and geographically disadvantaged communities. Addressing these gaps requires significant institutional support through modernization policies and localized capacity-building programs, ideally facilitated by industry-academia partnerships. In conclusion, the establishment of unified innovation transfer conduits is essential to expedite the transition of solutions from proofs-of-concept to farmer-ready tools, ensuring a targeted approach that caters to regional needs.

Abstract
Graphite films with large grain sizes have been reportedly obtained by using metal as catalysts, but the obtained graphite is mostly heavily wrinkled, thus containing defects that degrade its properties. We report the synthesis of mirror-like and large-grained graphite films with only a few nano kinks and controllable dimensions, achieved by using flat Ni-Mo alloy melts of the same lateral dimensions as the metal foils used to make this alloy melt. After formation of the graphite film, we deliberately evaporated out (much of the) Ni to produce a porous metallic substrate to dramatically weaken the substrate-graphite film interaction prior to cooling down to room temperature; with this step, the graphite film then had only a few nano kinks and a mirror-like appearance. The mirror-like graphite appears to be 100% AB-stacked with millimeter-sized grains that are much larger than the multi-micron grain size of highly oriented pyrolytic graphite and rivaled in size only by a small percentage of natural graphite. Our graphite films have an electrical conductivity of 5.59 × 106 S/m at 4 K and 7.75×105 S/m at 300 K. Tensile loading of macroscale samples showed an average Young’s modulus of 969 ± 69 GPa and average fracture strength of 1.29 ± 0.203 GPa, which are, to the best of our knowledge, the highest values reported for macroscale artificial graphite materials.

Published: February 2024

Abstract

Background
Tetramethylpyrazine, an alkaloid extracted from Ligusticum chuanxiong Hort (Umbelliferae), has been used in China for cardiovascular and cerebrovascular diseases because of its anti-inflammatory and antioxidant properties.
Objective
To investigate the effect of tetramethylpyrazine (TMP) on sepsis-associated encephalopathy (SAE) and its underlying mechanisms in autophagy regulation.
Methods
The Sprague-Dawley rat model was established using cecal ligation and puncture (CLP). They were randomly assigned to four groups: sham operation (Sham), (SAE), SAE + TMP (TMP), and SAE + rapamycin (RAPA). Administration of TMP (10 mg/kg/d, i.p.) or RAPA (10 nM/d, i.p.) once daily for 3 days before CLP. Twenty-four h after CLP, we assessed the vital parameters, neurobehavioral scores, water maze tests, hippocampal pathological structure, inflammation factors and autophagy associated proteins.
Results
TMP or RAPA injection significantly reduce escape latency (28.39%, 38.27%), rises the time spent in the target quadrant (39.29%, 53.57%) and the frequency of crossing the goal platform (100%, 111.76%), inhibit the levels of inflammatory factors IL-1β (49.32%, 50.74%), IL-6 (32.43%, 33.78%) and TNF-α (51.26%, 53.63%), downregulate proteins TLR1 (18.47%, 27.76%) and p62 (90.66%, 97.56%), upregulate proteins LC3II/I ratio (60.96%, 42.93%), ATG5 (58.10%, 15.41%) and Beclin1 (91.82%, 119.71%) compared with SAE group. Further, TMP-activated autophagy was reversed by used of chloroquine (CQ), and increase p62 (66.94%) expression and inhibit LC3II/I ratio (21.94%).
Conclusions
TMP expressed neuroprotective effects against SAE via activating autophagy, which provide experimental evidence for the clinically beneficial application to treat SAE.

Published: February 2024

Abstract

A thorough research was conducted to address water quality concerns in Villaverde, Nueva Vizcaya. The study focused on designing and evaluating the Biochar-Based Water Treatment System. This study was conducted to address the urgent need for the provision of potable water that is free from contaminants, particularly during times of increased turbidity caused by heavy precipitation. The basis of the system is rooted in the use of biochar, which is created particularly from coconut shells. This particular kind of biochar is renowned for its remarkable adsorptive qualities. A treatment system with a 250 mL/minute flow rate was constructed using a systematic design methodology. The efficacy of this system underwent comprehensive testing, including evaluations of both physical characteristics and bacteriological integrity. The findings of the study revealed a statistically significant enhancement in the transparency of water and the reduction of microbiological hazards, particularly when the flow rates were lower. The economic evaluations, including both the breakeven analysis and the Benefit-to-Cost ratio, further substantiated the feasibility of the system. Over 48 months, it is anticipated that the system would recover both its initial setup expenses and ongoing running costs, therefore providing a viable and cost-effective alternative for the community. The results indicate that the Biochar-Based Water Treatment System has the capacity to provide safe drinking water and offers significant economic benefits. This system represents a crucial advancement in the pursuit of sustainable water management in the Villaverde municipality.

Authors: zaher Omima zaher , dandshli Sabah 
Published: February 2024

Abstract
Background
Maternal satisfaction during a cesarean section is an important indicator for measuring the quality of obstetric anesthesia. This study aimed to determine the level of mothers’ satisfaction with spinal anesthesia for a cesarean section.
Methods
A cross-sectional study, conducted on a sample of the Syrian community, including 120 participants, between 5/29/2023 and 10/31/2023. A questionnaire prepared by the supervisor was used. The internal consistency measure was very good (Cronbach-α = 0.946), and included questions about (age, educational level, obstetric history, medical and surgical history...) and a measure of maternal satisfaction with spinal anesthesia (It consists of six topics)
Results
The ages of participants ranged between 21–50 years, with an average age of 30.25. The education level of the largest percentage of participants was university (71.7%). All participants were married (100%). More than half of the participants were parous (65.8%). Only (25%) of the participants experienced pain during surgery. Only (20%) of them suffered from nausea and vomiting postoperatively. Their satisfaction with spinal anesthesia for caesarean section was 60%. In general, the satisfaction rate regarding future spinal anesthesia procedure was (49.3%).
Conclusion
Overall maternal satisfaction can be considered acceptable, but preoperative evaluation and postoperative care are somewhat low. The relationship between the anesthesiologist and the patient and the doctor's attention during the surgical procedure were good. Explaining the benefits and risks of anesthesia techniques to patients, as well as taking their opinion into account, is very important when determining the type of anesthesia.
Solid-state synthesis, drug inclusion and 3D structure elucidation of a M12L8 cage-catenane
Authors: Marti-Rujas Javier , Elli Stefano , Famulari Antonino 
Published: February 2024

Abstract
The solid-state synthesis and fast crystallization of poly-[n]-catenanes self-assembled of mechanically interlocked metal organic cages (MOCs) is virtually unexplored due to the lack of suitable crystals for single crystal X-ray diffraction (SC-XRD) analysis, limiting their progress as advanced functional materials. Here we report the unprecedented inclusion of paracetamol in the cavities of amorphous materials constituted of M12L8, interlocked MOCs synthesized by mechanochemistry (solid-state) under kinetic control. Full structure determination of a low-crystallinity and low-resolution powders of the M12L8 poly-[n]-catenane including paracetamol has been carried out combining XRD data and Density Functional Theory (DFT) calculations using a multi-step approach. Each M12L8 cage contains six paracetamol guests (of a maximum of 10 that can include) which is confirmed by thermal analysis and NMR spectroscopy. The drug loading has been also carried out by the instant synthesis method using a saturated paracetamol solution in which TPB and ZnI2 self-assemble immediately (i.e., 1–5 seconds) encapsulating ⁓7 paracetamol molecules in the M12L8 nanocages under kinetic control also giving a good selectivity. The cargo nature of the M12L8 cages, the low toxicity of Zn(II) and the fact that 1global in an aqueous media is disassembled releasing the drug, makes poly-[n]-catenane 1global a potential drug delivery agent.

Authors: Wu Daqing , Lu Binfeng , Xu Zinuo 
Published: February 2024

Abstract
The price prediction of aquatic products is of great significance to the socio-economic development and fisheries industry. However, due to the complexity and uncertainty of the aquatic product market, traditional forecasting methods often struggle to accurately predict price fluctuations. Therefore, this study adopts a intelligence combination model to enhance the accuracy of aquatic product price prediction. Firstly, three decomposition methods, namely empirical wavelet transform, singular spectrum analysis, and variational mode decomposition, are applied to decompose the complex original price series. Secondly, a combination of bidirectional long short-term memory artificial neural network, extreme learning machine, and exponential smoothing prediction methods is used for cross-prediction on the decomposed results. Subsequently, these predicted result are input into the PSO-CS intelligence algorithm for weight allocation and generating combined prediction results. Empirical analysis is conducted using the data of daily sea purchase price of larimichthys crocea in Ningde City. The combination prediction accuracy with PSO-CS weight allocation is found to be higher than that of single model predictions, yielding superior results. Based on the weight allocation intelligent combinatorial modelling, the prediction of aquatic product prices demonstrates higher accuracy and stability, enabling better adaptation to market changes and price fluctuations.

Abstract
In a diversified cropping system, the kinds of tillage methods and weed management choices adopted exert a significant influence on soil microbiome which has a bearing on crop productivity. The synergetic impacts of such practices on soil microbiome in association with yield under cotton-maize-Sesbania rostrata rotation with CA have not been extensively explored thus far in Southern India. Therefore, a 4-years CA experiment was undertaken to investigate the impact of tillage and weed management on soil microbiome and fungal diversity at 30 DAS and tasselling of maize, crop yield and identify a sustainable tillage and weed management which can provide nature-based solution. Three tillage practices; T1:CT(C)-CT(M)-fallow (NSr), T2:CT(C)-ZT(M)-ZT(Sr) and T3:ZT + R(C)-ZT + R(M)-ZT + R(Sr) and weed control tactics involved; W1-chemical weed control, W2-chemical (herbicide) rotation, W3- integrated weed management (IWM) and W4-non-weeded control laid out in split-plot design. Rhizosphere soil and rhizoplane samples were collected from the respective plots at 30 DAS after herbicides application and tasselling. Analysis for microbial population, enzyme and microbial activities viz., soil basal respiration (SBR), metabolic quotient (qCO2), microbial quotient (qMB), soil microbial biomass carbon (SMBC) and nitrogen (SMBN) was done duly following standard procedures. The rRNA gene sequencing with 18s was performed with rhizosphere soil and rhizoplane fungi isolated at tasselling. Yield was recorded at harvest. The salient findings indicated; a decline in enzyme activities, microbial population, microbial activities at initial stages (30 DAS) due to impact of herbicides which later on increased by tasseling except qCO2 which decreased. These biological properties were higher under T3 and non-weeded control followed by IWM except qCO2 which showed a decreasing trend relative to T1, T2 and W1, W2 at both sampling stages of maize. Kernel yield (KY) and System yield (SY) were enhanced by T3 and IWM, herbicides treated plots (W1 and W2) compared to T1, T2 and non-weeded control. Talaromyces flavus, beneficially rhizosphere soil inhabitant was identified in T3 in combination with IWM. Considering both crop productivity and soil biological assessment, T3 and IWM was considered as best treatment combination among all others with SY (4453 kg ha− 1). These findings signify the importance of adopting reduced tillage (T3) and IWM for the farmer while striving for Nature-based solution.
