The theory of functions of a complex variable is a hybrid of vector algebra and ordinary algebra. It makes it possible to work with vector quantities as with algebraic ones. The modern theory of functions of a complex variable was created by the French mathematician Augustin Cauchy (1789-1857), later it was rapidly developed and found its application in solving various problems of physics—in aerodynamics, hydrodynamics, elasticity theory, etc. However, this theory is used exclusively for solving problems on the plane. Therefore, the next natural step is to extend this theory into space, so that we could obtain the solution of physical problems directly in space. The creation of such a theory is associated with some serious problems, for example, the appearance of so-called zero divisors, spatial complex numbers that are not equal to zero but when multiplying for some reason give zero. There is also a Frobenius theorem which prohibits the propagation of complex numbers into a space without abandoning some ordinary algebraic operations (for example, commutative multiplication). In this article an attempt is made to construct a theory of spatial complex functions (shortly, tunnel mathematics) in which zero divisors do not appear and all the usual algebraic operations are preserved. The possibility of applying this theory to some problems of the theory of elasticity and hydrodynamics (the steady Lamé and Navier-Stokes equations) is also considered.

Intercropping, the cultivation of two or more crops at the same time in the same field, is a common practice in North Korodfan of Sudan in traditional farms of smallholders. This experiment conducted in rainy season (2019/2020) to investigate the effect of intercropping on yield and yield components of cowpea (Vigan unguiculta L), sorghum (Sorghum bicolor L. Moench) and roselle (Hibiscus sabdariffa var. sabdariffa L) intercropped at different spatial arrangements. The experiment consisted of nine treatments: three sole crop of Sorghum Cowpea, and Roselle and eight spatial arrangements of 1:1, 1:2, 2:1, and 2:2 rows of Cowpea with each of Sorghum or Roselle. A randomized complete block design (RCBD) with four replications was used. The results showed that intercropping treatments had significant (P ≤ 0.05) effect on most of the parameters measured on Sorghum, Cowpea and Roselle intercropping. For sorghum: the spatial arrangements 2:2 and 1:1 had the significant highest 100-seed weight (2.9 g) and final seed yield (0.34 ton/ha). For cowpea: the treatment 2:2 had the highest number of pods per plant, 100 seed weight, and shoot dry weight for cowpea. The intercropping 2C:1S had a highest cowpea seed yield (4.2 ton/ha) compared to others spatial arrangements. For roselle the intercropping 2C:2R (two rows of cowpea alternated with two rows of roselle) had the higher number of calyx per plant (19.7) and calyx yield (9.7 g/plant) than the other spatial arrangements. From this study, the practice of planting two rows of cowpea alternating with two rows of sorghum is recommended for farmers under rain-fed sector.
套作，即在同一块土地上同时种植两种或两种以上的作物，是苏丹北Korodfan小农传统农场的一种常见做法。本试验于2019/2020年雨季，研究了不同空间安排下间作对豇豆(Vigan unguiculta L)、高粱(sorghum bicolor L. Moench)和玫瑰(Hibiscus sabdariffa var. sabdariffa L)产量及产量构成的影响。试验共设高粱、豇豆和蔷薇3个单作处理，豇豆与高粱或蔷薇各作1:1、1:2、2:1和2:2行8个空间布置。采用随机完全区组设计(RCBD)，共4个重复。结果表明，套作处理对高粱、豇豆和玫瑰套作的大部分指标影响显著(P≤0.05)。高粱的百粒重(2.9 g)和最终种子产量(0.34 t / hm2)以2:2和1:1的空间布置最高。豇豆:以2:2处理单株荚果数、百粒重和茎干重最高。与其他空间安排相比，间作2C:1S的豇豆产量最高(4.2吨/公顷)。对于玫瑰，2行豇豆与2行玫瑰交替种植2C:2R的单株花萼数(19.7个)和花萼产量(9.7 g/株)高于其他空间安排。通过本研究，建议雨养区农民采用两行豇豆和两行高粱交替种植的做法。

A 0.38C steel with 1.97Mn, 1.34Si, 0.8Cr and 0.29Mo (wt. %) bainitic steel melted in a lab scale induction furnace was hot forged and subjected to annealing, austenitizing above Ac3 temperature and in the inter critical temperature range were normalized or austempered in the temperature between 350 to 500 oC to get a versatile range of microstructure with bainite as a major phase. In the annealed condition the steel showed acicular ferrite with pearlite and in the normalized condition from above Ac3 temperature, bainitic ferrite with 7% retained austenite. When the steel is continuously cooled post intercritical austenitization treatment, the microstructure showed ferrite, bainite and pearlite. Austenitization above Ac3, followed by austempering at different temperatures resulted in carbide free bainitic microstructure consisting of bainitic ferrite and austenite between 7 and 16%. Austenitization in the inter critical temperature followed by austempering at different temperatures showed ferrite, banitic carbide and pearlite.

This paper analyzes the monthly average temperature of Baotou City from January 1, 1973, to December 31, 2022. The data comes from the R language worldmet dataset, with 600 data. Observing the time series chart shows the data have obvious periodicity and seasonality, and there is no trend. The order ARIMA(1,0,1) s determined by observing the ACF and PACF diagrams, but since there is a trend term of AR, a difference is added to get P=1, D =1, Q=1. By comparing the AIC, BIC and σ^2 values of ARIMA(1,0,1) and ARIMA(1,0,1) , the residual analysis diagrams are observed. The residual analysis diagrams are not very different, which reflects that the residual is white noise. The AIC, BIC and σ^2 values of the former are all smaller than those of the latter, so the time series model is determined as ARIMA(1,0,1) , and the expression is, . Where represents the predicted value at time point t, and represent the original observed value at time point t-1 and t-12, respectively, and and represent the residual term at time point t-1 and t-12, respectively. The model takes into account the seasonality and trend of meteorological data and can fit the data well and make future temperature predictions. After residual analysis and model selection, the prediction effect of this model is good, the error is small, and it can provide a certain reference value. However, there may be shortcomings such as seasonal effects on forecast accuracy, which raises the need to improve models and study more meteorological data features. In general, meteorological data prediction based on time series analysis is an important research field, and more in-depth research and exploration are needed in the future to improve the prediction accuracy and provide better support for decision-making in the field of meteorology and climate.
本文分析了包头市1973年1月1日至2022年12月31日的月平均气温。数据来自R语言worldmet数据集，包含600个数据。观察时间序列图，数据具有明显的周期性和季节性，不存在趋势。顺序ARIMA(1,0,1)是通过观察ACF和PACF图确定的，但由于存在AR的趋势项，因此添加一个差值以得到P=1, D =1, Q=1。通过比较ARIMA(1,0,1)和ARIMA(1,0,1)的AIC、BIC和σ^2值，得到残差分析图。残差分析图相差不大，反映残差为白噪声。前者的AIC、BIC和σ^2值均小于后者，因此确定时间序列模型为ARIMA(1,0,1)，表达式为，。式中为时间点t的预测值，和分别为时间点t-1和t-12的原始观测值，和分别为时间点t-1和t-12的残差项。该模型考虑了气象资料的季节性和趋势，能很好地拟合气象资料，并能对未来气温进行预测。经过残差分析和模型选择，该模型预测效果好，误差小，可以提供一定的参考价值。然而，也可能存在诸如季节影响预报精度等缺点，这就提出了改进模式和研究更多气象数据特征的需要。总的来说，基于时间序列分析的气象数据预测是一个重要的研究领域，未来需要进行更深入的研究和探索，以提高预测精度，更好地为气象气候领域的决策提供支持。

This study deals with bulimia nervosa (BN) that is a serious and potentially life-threatening eating disorder, which is characterized by binge-eating and extreme weight control policy. It is a distressing and disabling disorder followed by compensatory purging behaviors, such as self-induced vomiting, misuse of diuretics and laxative; and non-purging behaviors, such as excessive exercise, severe dieting, and long-time fasting. Physical, emotional, mental, sexual, and verbal abuse can also develop bulimia nervosa. BN patients frequently have a normal weight, but sometimes they may be underweighted or overweighed. Bulimia nervosa is frequently accompanied with the effects of normal physiologic functioning. The most common causes of morbidity and mortality among bulimia nervosa patients are electrolyte and metabolic disturbances. This study reviews the key features and associated problems of bulimia nervosa and its negative effects in global healthcare environment.

Series of primes are considered in three levels of sets of numbers (N)(Z)(Q), where – series of prime numbers in the set of natural numbers (PN), – a series of integer primes in the set of integers (WPN), – a series of rational primes in the set of rational (fractional) numbers (FPN). In series and the abscissa is taken as a complete series of integers , and for a series of prime numbers the positive right side of the x-axis is taken as a series of natural numbers . It is proved that the FPN set contains four types in the quadrants of the Cartesian coordinate system, the WPN set includes two mirror-opposite lines (the left one in quadrants II and IV and the right one in quadrants I and III). Subtraction from the next term WPN and PN of the previous component of the series gives new series of increments. Converting from decimal to binary gives for the series WPN and PN, as well as their increments, the rational root 1/2 of the Riemann zeta function on the second vertical of the binary expansion. Such a transformation makes it possible to obtain the block structure WPN and PN of partitioning the original series into blocks, and then the groups starting from the number 2. Using the example of block No. 8168 for the series PN, we proved the decomposition of groups into separate quanta, starting from the number 2, by asymmetric wavelets in the form solitary waves (solitons) with variable amplitude and oscillation period with a maximum relative error of 0.1%.

The overlapping grid method is a novel region segmentation and grid combination strategy. Based on this method, the aerodynamic characteristics of lineup vehicles in meeting conditions are simulated in this paper. Firstly, the data obtained from the single-vehicle simulation is compared with the wind tunnel test data, and the error value is relatively small, which verifies the validity of the overlapping grid method. After that, simulation was carried out to analyze the changes of flow field around the cars in formation, and the differences between the front and rear cars in formation were summarized. Finally, the vehicle pressure field, velocity field, aerodynamic coefficient and torque coefficient were statistically analyzed, and the influence of the car meeting on the aerodynamic characteristics of the queue was studied.

The adoption of artificial intelligence (AI) in the pharmaceutical industry has the potential to revolutionize supply chain management, enabling pharmaceutical companies to optimize their logistics and production processes while improving product quality and overall patient safety. This paper explores the value of AI technology in optimizing and implementing supply chain data for pharmaceutical companies. It reviews case studies from leading pharmaceutical companies such as Pfizer, Amgen, GlaxoSmithKline, Merck, and Roche, and examines how they are leveraging AI-powered solutions to optimize their logistics, production, and quality control processes.
