For a bounded operator T acting on an infinite dimensional separable Hilbert space H, we prove the following assertions：（i） If T or T＊ ∈ SC, then generalized a- Browder＇s theorem holds for f（T） for every f ∈ Hol（σ（T））. （ii） If T or T＊ ∈ HC has topological uniform descent at all λ ∈ iso（a（T））, then generalized Weyl＇s theorem holds for f（T） for every f ∈ Hol（σ（T））. （iii） If T ∈ HC has topological uniform descent at all λ ∈（T）, then T satisfies generalized Weyl＇s theorem. （iv） Let T ∈ HC. If T satisfies the growth condition Gd（d 〉 1）, then generalized Weyl＇s theorem holds for f（T） for every f ∈ Hol（σ（T））. （v） If T ∈ SC, then, f（OssF＋（T）） = aSBF＋（f（T）） for all f ∈ Hol（σ（T））. （vi） Let T be a-isoloid such that T＊ ∈ HC. If T - AI has finite ascent at every A ∈ Eσ（T） and if F is of finite rank on Hsuch that TF = FT, then T ∈ F obeys generalized a-Weyl＇s theorem.

The ultrastructure and physicochemical and thermal properties of Palm Kernel Shells (PKS) in comparison with Coconut Kernel Shells (CKS) were investigated herein. Powder samples were prepared and characterized using Surface Electron microscopy (SEm) and Transmission Electron microscopy (TEm). Chemical and elemental constituents, as well as thermal performance were assessed by Van Soest method, TEm/EDXA and SEm/EDS techniques. Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) were also performed for thermal characterization. SEm/EDS and TEm/EDXA revealed that most of the PKS and CKS materials are composed of particles with irregular morphology;these are mainly amorphous phases of carbon/oxygen with small amounts of K, Ca and mg. The DSC data permitted to derive the materials’ thermal transition phases and the relevant characteristic temperatures and physical properties. Thermal Transition phases of PKS observed herein are consistent with the chemical composition obtained and are similar to those of CKS. Nonetheless, TGA/DTG showed that the combustion characteristics of PKS are higher than those of CKS. Taken together, our results reveal that PKS have nanopores and can be efficiently used for 3D printing and membrane filtration applications. moreover, the chemical constituents found in PKS samples are in agreement with those reported in the literature for material structural applications and thus, present potential use of PKS in these applications.

Introduction: The mNRI (masgutova Neurosensorimotor Reflex Integration) method was developed in 1989 in Russia and has spread world-wide to treat individuals with certain types reflex development deficits, behavior disorders, disorders of speech or language development, and learning disabilities. mNRI is based on techniques called “repatterning” or remodulation, meaning re-education, recoding the reflex nerve pathways specific for dynamic and postural reflex schemes. Objectives: Repatterning activates the extra pyramidal nervous system responsible for automatic mechanisms and processes, the extension of links between neurons, the growth of neural nets, myelination, and the creation of new nerve routing. This potential result was tested utilizing urinary measurements of the following neurotransmitters: epinephrine, norepinephrine, dopamine, DOPAC, serotonin, 5-HIAA, glycine, taurine, GABA, glutamate, PEA, and histamine. methods: Neurological impact of the masgutova Neurosensorimotor Reflex method on the magnitude of changes in neurotransmitters was assessed by an external controlled and double-blind method using patients from one of the four diagnosis groups: 1) global developmental disorders;2) cerebral palsy, Traumatic Brain Injury (TBI), Acute Brain Injury (ABI), and seizures;3) ADD/ADHD;and 4) anxiety disorders. Results: The post-mNRI results in participants show a tendency for regulation of the above neurotransmitters resulting in their calming down, decrease of hypervigilance, stress resilience increase, improvements in behavioral and emotional regulation, positive emotions, and cognitive processes control. Conclusion: The application of the masgutova Neurosensorimotor Reflex method as a therapy modality offers a novelty paradigm for the treatment using neuro- and immune-modulation technologies presenting a non-pharmaceutical approach, based on use of neurosensorimotor reflex circuit concept.

The physiological markers of 310 individuals aged 2 through 19 were evaluated for the effects of the masgutova Neurosensorimotor Reflex Integration method on their four body systems: respiratory, cardiovascular, digestive, and nervous systems of individuals with neurodevelopmental deficits—cerebral palsy (CP), seizures, traumatic and acute brain injury, attention deficit and hyperactive disorders (ADD, ADHD), autism spectrum disorders, anxiety, post-trauma and post-traumatic stress disorders. We found that 53.33% of physiological markers and 66.67% of reflex patterns on the pre-test demonstrated to be poorly functioning. Both evaluation results showed statistically significant improvements after 8-days of intensive training using the masgutova Neurosensorimotor Reflex Integration method. Improvements according to 60.0% of the physiological markers positively correlated with functionality gains in 77.5% of reflex patterns in all four study groups compared to the control group, which did not receive the Reflex Integration training program (p-value magnitude of improvement depended upon the severity of symptoms indicating the essentiality for individualized training in accordance with the diagnosis and individual neurological deficits. Results of this study show that reflex integrative techniques can lead to a reduction of stress and other negative factors blocking health homeostasis, limiting perception, and causing dysregulation in behavior and emotions, especially following traumatic events. Positive changes in physiological markers and reflex pattern functions indicate potential benefits for survival and stress resiliency through supporting neuro-physiological and neuro-psychological aspects of overall health and well-being in individuals with neurological deficits.

大西洋研究公司提出了一种分析固体发动机药柱燃烧状况的计算机程序化方法,本法可直接计算局部燃速对已燃药厚的平均燃速的比。包括使用标准批检验发动机的某些特殊试验在内,对几种不同构形的中心孔药柱燃速比的药厚变化效应(“虹效应”)及数值进行了评估。分析表明这种燃速比的药厚效应是由制造方法引起的.实际上与尺寸、长径比、控制温度、燃速和药厚等发动机参数无关。提出了一种假说,认为此种药厚效应的起因与推进剂富粘合剂层的条痕结构有关,而条痕的形状又与制造方法及药柱构形有关。迄今积累的数据表明,对圆孔药柱而言,事先固定芯子的装药比先浇注后插入芯子的装药燃速约高3—4%。药柱上的各种槽沟往往限制了各点虹效应的精度确定,尽管在全部的构形中均可看到总的虹效应,且最大与最小值的差一般均在3—6%范围内变动。本文给出了各种发动机的燃速比数据,其推进剂重量从10磅左右至2000磅,长径比1:1至8:1,药厚从小于1英寸到大于7英寸,药形有槽管状、锥柱状、一端和两端的圆柱状。

The objective of this study was to analyze the nutrient composition and variability of university dining hall food waste and compare it with common feedstuffs used in ruminant and monogastric diets. Food waste was categorized into two initial streams: mainstream (mS) from the serving line and vegetable preparation (VP) from the kitchen. Waste was collected from the Kramer Dining Center, Kansas State University, resulting in 30 daily samples. Waste was weighed and ground to homogenous particle size. Daily samples of mS and VP were analyzed for nutrient composition, where results were combined to calculate the nutrient profile of a hypothetical mixed food waste stream (mX) composited by total weight. Data were analyzed using R statistical software (v 4.2.2). moisture and neutral detergent fiber (NDF) were greater in VP (P , while ether extract (EE) was less compared to mS and mX. Crude protein (CP) was greater (P mS and mX streams compared to VP. The total digestible nutrients (TDN) and energy were greater in mS food waste than in mX, which was also greater than VP (P content, measured by standard deviation, was similar (P > 0.05) among streams for NDF, nitrogen-corrected neutral detergent fiber, acid detergent insoluble crude protein, CP, ash, lignin, and digestible and metabolizable energy. Dry matter and EE variation were greater (P mS, whereas VP was less (P mpared to mX. Standard deviation increased (P mS and mX for neutral detergent insoluble crude protein, TDN, and gross energy when compared to VP. Despite having 70% - 80% moisture, dining hall food waste does have nutritive value and the potential to be included in ruminant and monogastric diets. Further research needs to be done to understand the value of including it in animal diets.

The copolymerization of styrene (St) and acrylonitrile (AN) complexed with CuCl_2 monomer by a free radicalmechanism was performed using benzoyl peroxide as an initiator at 65℃ under N_2 atmosphere for 150 min. The rate ofpolymerization (R_p) was found to increase linearly with the concentration (in mol/L) of CuCl_2, AN and St through scalingrelations. The activation energy of the copolymerization process in the presence and absence of CuCl_2 was found to be46.5 kJ/mol and 102 kJ/mol, respectively. The viscosity average molecular weigh of the copolymer and the k_p^2/k_t ratio weredctermired to further assess the accelerating effect of CuCl_2 on the copolymerization process. The copolymerization processin the presence of CuCl_2 has a radical complex mechanism.
