AbstractResponding to a call for national reform of mathematical education, as well as a college-wide revision of general education (GE) requirements, we describe a new entry-level, GE course focused on the humanitarian utility of mathematics. This includes a detailed overview of how we taught the course using a Humanitarian MATLAB Lab Manual developed collaboratively with undergraduate students within an applied math program. A PRIMUS edition of this manual with complete MATLAB materials for a GE course is included as an Appendix for interested readers. A variety of social justice issues including peace-building after modern civil wars, continued cancer risk after Chernobyl, gang reduction, various dimensions of human trafficking, the use of a tractor and herbicide in subsistence farming, equitable resource distribution during the Syrian refugee crisis, and access to HIV vaccines are included in this special edition of the manual. 相似文献

Lactate dehydrogenase (LDH) and its isoenzyme profile, Nacety-β-d-glucosaminidase (NAG) and alanine aminopeptidase (AAP) enzyme activities were measured in 21 cases with well documented acute
untreated urinary tract infections (UTI) and compared with a group of 68 normal healthy subjects matched for age and sex.
Urinary NAG, AAP and LDH total activities were highly elevated (3–30 fold for NAG, 2–10 fold for AAP and 2–50 fold for LDH
over upper limit of normal) in upper tract infections. In lower tract infections there was a marginal elevation in NAG and
LDH while AAP activity was very high; though there was no overlap. Further, the isoenzyme profile of LDH showed predominance
of LD-5 isoenzyme in all cases of pyelonephritis, while it was completely absent in all the cases of lower tract infections.
We conclude that urinary NAG and LDH-5 isoenzyme would serve as specific non-invasive parameters for differential localization
of urinary tract infections. 相似文献

该系统具备了神经网络自学习和模糊推理处理不确定信息的能力。通过仿真实验和仿真结果表明,该系统能有效地进行农业设备样本模式的模糊量化处理,极大地改善了神经网络训练的收敛性。通过对模糊神经网络系统的多次测试,当实际数据与学习样本接近时,该系统能够得出与样本相同的预测结果;当输入数据与学习样本偏离时,该系统依然能够得出准确的预测结果,达到了农业设备剩余寿命预测的要求。 相似文献

There is an increasing awareness of the social dimension in mathematics teacher education. Collaboration and co-operation
are regarded as key factors in professional development. In this paper I will analyse some tensions that might arise when
the professional development of mathematics teachers is considered a collective enterprise. I will present phenomenological group interview as a method that is designed to reveal the collective character of teacher development. Some primary teachers’
collective reflections on an ongoing professional development process will be interpreted by focusing on the concepts of routine and collective orientation. The discussion is centred on the ambivalence of routines, as facilitators of practice, and collective orientations, as socially-agreed-upon
knowledge base, for mathematics teachers’ professional development.

Thermal injury is associated with biochemical changes. The present study was undertaken to investigate relation of oxidative
free radical generation and related biochemical parameters in burn trauma. The specific aim was to compare the levels of serum
lipid peroxide, Ceruloplasmin and Uric Acid in burn patients during treatment with Silver Sulfadiazine Cream and honey therapy.
It is a single blind prospective controlled study involving comparison of biochemical changes after treatment with silver
sulfadiazine and honey treatment in burn injury. In burn trauma, there is excessive activity of free radicals at the site
of injury. This is reflected in elevated blood levels of Lipid peroxide, Ceruloplasmin & Uric Acid. Honey therapy was was
shown to decline the levels of serum Lipid peroxide, while there was mild increments in serum Ceruloplasmin levels whereas
there was no significant effect on serum Uric Acid levels as compared to silver sulfadiazine treatment. Honey therapy seems
to accelerate the process of healing. It has positive effect in reducing oxidative stressful state in burn trauma than the
silver sulfadiazine treatment that results in rapid wound healing. 相似文献
