Authors: BAI Long 
Published: June 2024

In multi-body system dynamics modeling, the body which rotate in space is complex and not easily to be expressed by Newton method, because the space rotation is realized by multi-joints rotation coupling with different direction. In this exploration, the Lie group variational integrator method is used to the dynamics modeling problem of multi-body system with three orthogonal direction joints coupling. Firstly, a mechanism accords with Cardan rotation regular is designed which can represent 3 different directions coupling, the kinematics model is derived out by matrix operation without triangle function. With inertia matrix and mass matrix of the multi-body system according to the topology structure, and the Lagrange function is built, and the dynamics equation is derived out with Lie group variational integrator method. With Legendre transformation, the Hamilton dynamics model is obtained. The differential computation of the momentum part is avoided, the scale of the dynamics model is greatly reduced. The Hamilton dynamics model with two different kinematics part are compared in simulation. The simulation results indicates that the different kinematic expression can lead to different structure conservation characters under same numerical computation method. This exploration offers a benefit attempt of using geometry method to dynamics modeling problem of tree structure multi-body system with different structure rotation matrixes coupling.

Comparative Physico-Chemical Properties of Microcrystalline Cellulose (MCC) from Dracaena arborea Stems Processed by Acid and Alkali Hydrolysis
Authors: Ordu J. I. , Oraeluno J. N. 
Published: June 2024

Cellulose, an abundant renewable biodegradable polymer, is often recognized as a potential feedstock for chemical productions with its versatility being extended as a useful structural and functional material for pharmaceutical and industrial applications. It is a straight chain polymer constituent in cell walls of most plants consisting of D-glucose units devoid of coiling or branching. Three basic types of cellulose existing in nature are alpha (?), beta (?), and gamma (?). Microcrystalline cellulose (MCC), which occurs in the form of purified and partially depolymerized ?-cellulose from plants such as D. arborea stem, was derived by severe alkaline and acid hydrolysis. The MCC derived was of the percentage yield, 54.3 and 61.05%, and pH of 7.80 and 6.80 respectively, from the two hydrolytic pathways. Physico-technical analysis resulted in values similar to those recommended in the official monograph. Proximate principles of the extracted MCC depicted similar percentage fiber, lipid and protein content, as 65.78%, 0.6 and 0.4% respectively. Elemental analysis also showed similar composition of sodium and iron content as 41% and 35% respectively with absence of lead and other deleterious materials. FTIR analysis suggested the presence of carbonyl groups, 6- membered cyclic ring (aromatic structure) with ortho and meta - OH substitution and long aliphatic chains. Micromeritic analysis of the MCC gave average particle size of 112.46µm, coefficient of curvature (Cc) and coefficient of uniformity (Cu) as 1.14 and 1.23 for acid hydrolysed and average particle size of 358µm, Cc (1.003) and Cu (1.204) for alkaline hydrolysed. The x-ray diffraction study gave a percentage crystallinity index (CI) of 9.09 at 2q = 22 and 2q = 34 especially for alkaline hydrolysed although that of the acid hydrolysed was not determined but the percentage CI was suspected to be higher based on the particle size index.

Published: June 2024

The rise of AMRs has changed our perception and also our interaction with automation. At the centre of this transformation are navigation and also obstacle avoidance, both equally critical requirements for deploying AMRs in various settings. This thorough review examines the front-line progress in navigation and collision avoidance for AMRs, touching upon numerous contemporary approaches and methodologies algorithms along with technologies that seek to enhance functionality. The paper offers a detailed review of the established approaches, such as rule-based approaches; potential fields; reactive navigation systems as behaviour systems and path following algorithms that have been amassed to face the challenge in practice. Conversely, technological developments in terms of machine learning, computer vision sensor fusion and SLAM algorithms as well as edge computing are discussed in the aspect that they have an unprecedented impact on AMR navigation. Global and local approaches are approached through universal international optics and also national adjustments that reveal the peculiarities of separate countries. The Data Analysis and Processing section points out the importance of technologies, which define AMR performance. Due to the constraints obtained from previous studies, it is very clear that additional research has to be done in relation to concentrating on fixing gaps under the controlled environments and using standard benchmarks; sensor heterogeneity issues; and also practical implementation of theoretical aspects. Briefly speaking, this review serves as a map for the intricate landscape of AMR navigation and also obstacle avoidance. Its main goal is to support the ongoing debate, stimulate innovation and identify new research directions in a rapidly changing world of autonomous mobile robotics that breaches the existing deployment barriers.

Современная система государственных закупок является основным механизмом, позволяющим различным секторам экономики получать доступ к бюджетным средствам. От эффективности работы вышеуказанной системы зависит, с одной стороны, качество выполнения государством своих функций и предоставления государственных (муниципальных) услуг, с другой стороны, доступ к государственному заказу является фактором активизации хозяйственной деятельности негосударственного сектора. Аудит в сфере публичных закупок - один из эффективных инструментов, позволяющих улучшить контроль за финансовыми потоками, выявить потенциальные риски неэффективного использования бюджетных средств. По данным Счетной палаты Российской Федерации на протяжении последних 7 лет средний удельный вес государственных и корпоративных закупок в совокупном объеме номинального ВВП составил 28,5 % (в 2022 году – 28,5%). Каждый год участниками закупок становятся более 100 тыс. заказчиков и 400 тыс. поставщиков.
The modern public procurement system is the main mechanism that allows various sectors of the economy to access budgetary funds. On the one hand, the quality of the state's performance of its functions and the provision of state (municipal) services depends on the effectiveness of the above-mentioned system, on the other hand, access to public procurement is a factor in activating the economic activity of the non-governmental sector. Audit in the field of public procurement is one of the effective tools to improve control over financial flows and identify potential risks of inefficient use of budget funds. According to the Accounts Chamber of the Russian Federation, over the past 7 years, the average share of government and corporate purchases in the total nominal GDP amounted to 28.5% (in 2022 – 28.5%). Every year, more than 100 thousand customers and 400 thousand suppliers become participants in purchases.

Restoring South African subtropical succulent thicket using Portulacaria afra: root growth of cuttings differs depending on the harvest site during a drought

Published: June 2024

The restoration of succulent thicket (the semi-arid components of the Albany Subtropical Thicket biome endemic to South Africa) has largely focused on the reintroduction of Portulacaria afra L. Jacq—a leaf- and stem-succulent shrub—through the planting of unrooted cuttings directly into field sites. However, there has been inconsistent establishment and survival rates, with low rates potentially due to a range of factors (e.g., post-planting drought, frost or herbivory), including the poor condition of source material used. Here we test the effect of parent-plant and harvesting site on the root development of P. afra cuttings in a common garden experiment. Ten sites were selected along a ∼110 km transect, with cuttings harvested from five parent-plants per site. Leaf moisture content was determined for each parent-plant at the time of harvesting as a proxy for plant condition. Root development—percentage of rooted cuttings and mean root dry weight—was recorded for a subset of cuttings from each parent-plant after 35, 42, 48, 56, and 103 days after planting in a common garden setting. We found evidence for cutting root development (rooting percentage and root dry mass) to be strongly associated with harvesting site across all sampling days (p < 0.005 for all tests). These differences are likely a consequence of underlying physiological factors; this was supported by the significant but weak correlation (r2 = 0.10–0.26) between the leaf moisture content of the parent-plant (at the time of harvesting) and dry root mass of the cuttings (at each of the sampling days). Our findings demonstrate that varying plant condition across sites can significantly influence root development during dry phases (i.e., intra- and inter-annual droughts) and that this may be a critical component that needs to be understood as part of any restoration programme. Further work is required to identify the environmental conditions that promote or impede root development in P. afra cuttings.
Andrographolide induces protective autophagy and targeting DJ-1 triggers reactive oxygen species-induced cell death in pancreatic cancer
Authors: Wang Zhaohong , Chen Hui , Cai Xufan , Bu Heqi , Lin Shengzhang 
Published: June 2024

Background
Andrographolide (Andro), an extract of Andrographis paniculate (Burm.f.) Wall. ex Nees (Acanthaceae), possesses diverse biologically active properties. However, the precise mechanisms and effects of Andro on pancreatic cancer (PC) remain unclear.

Methods
The cytotoxic potential of Andro and underlying mechanism towards PC cells was investigated through in vitro experiments and a xenograft mouse model. PC cells were first subjected to varying concentrations of Andro. The reactive oxygen species (ROS) was assessed using flow cytometry and DCFH-DA staining. The apoptosis rate was detected by flow cytometry. Additionally, western blot was applied to evaluate the expression levels of cleaved-caspase-3, DJ-1, LC3-I, LC3-II, and p62. To further elucidate the involvement of ROS accumulation and autophagy, we employed N-acetylcysteine as a scavenger of ROS and 3-Methyladenine as an inhibitor of autophagy.

Results
Andro demonstrated potent anti-proliferative effects on PC cells and induced apoptosis, both in vitro and in vivo. The cytotoxicity of Andro on PC cells was counteracted by DJ-1 overexpression. The reduction in DJ-1 expression caused by Andro led to ROS accumulation, subsequently inhibiting the growth of PC cells. Furthermore, Andro stimulated cytoprotective autophagy, thus weakening the antitumor effect. Pharmacological blockade of autophagy further enhanced the antitumor efficacy of Andro.

Conclusion
Our study indicated that ROS accumulation induced by the DJ-1 reduction played a key role in Andro-mediated PC cell inhibition. Furthermore, the protective autophagy induced by the Andro in PC cells is a mechanism that needs to be addressed in future studies.
