conclusions this study revealed the noticeable popularity of cam in patients suffering from chronic rheumatologic diseases, mostly due to their dissatisfaction with conventional treatments. patients and methods in this cross-sectional study, 100 randomly selected patients, with different diseases, were questioned about demographic data, disease duration, the type of cam used, reasons, visit int...

The search for fast unitary transforms and the need for data compression in linear systems are complementary issues. Compression requires the definition of a threshold dependent on the condition number, which is invariant over the unitary group. With respect tot this threshold it is shown that the SVD is the optimal tool. Considerations in connection with the Kronecker product and direct sum of...

In the directed Steiner tree (DST) problem, we are given an $n$-vertex edge-weighted graph, a root $r$, and collection of $k$ terminal nodes. Our goal is to find minimum-cost subgraph that contains path from $r$ every terminal. We present $O(\log^2 k/\log\log{k})$-approximation algorithm for DST runs in quasi-polynomial time, i.e., time $n^{{poly}\log (k)}$. By assuming projection game conjectu...

The relationship between wheat head blast incidence (I; proportion of diseased heads in a sample) and severity (S; the average area sample heads) was studied with aim determining whether could be reliably predicted from incidence. Data were collected two main sources: a) EPAMIG (non-treated) field experiments spanning seven years (2013–2019 three cultivars) designed to evaluate effect planting ...

background: there are two types of primary dysmenorrhea (spasmodic and congestive) which differ from each other in terms of the time of menstrual cycle outbreak, pain quality and other symptoms. the present study aimed to determine the effect of acupressure at the sanyinjiao point (sp-6) on severity of menstrual symptoms (primary outcome) and the duration of resting time as well as the number o...

background: humans have been involved with the phenomena of pain and pain relief from the ancient times. back pain is the most common pain. in fact, eight out of ten people experience it in their lifetime. however, individuals with specific jobs, including nurses, are faced with this problem more. nursing is in the top ten careers suffering from the most severe musculoskeletal injuries. there a...

background: to determine the prevalence and patterns of complementary and alternative medicine (cam) use in urban population in isfahan. methods: in a cross–sectional study through two-stage sampling methods, 870 individuals were selected from isfahan province, center of iran. we selected 20 clusters randomly and chose one household from each cluster by chance then 24 households were included...

abstract background: children suffering from cancer frequently use complementary and alternative medicine (cam). most of people do not disclose using cam to their physicians as they fear to be blamed or prohibited using them. some of these products may interfere with the conventional remedies. the aim of this study was to investigate the frequency and characteristics of cam use in pediatric onc...

background : using complementary and alternative medicine (cam) has been increased worldwide during last years and women are the greatest users of these methods especially in the pregnancy period. due to lack of adequate information, this study aimed to assess the status of using complementary and alternative medicine by women in the pregnancy period methods: in this cross-sectional study, 599 ...

in this paper using strongly duplexes we introduce a new class of (semi)hypergroups. the associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup. two computer programs written in matlab show that the two groups $z_{2n}$ and $z_{n}times z_{2}$ produce a strongly duplex and its associated hypergroup is a complementary feasible hypergroup.
