Generalized Ridges and Ravines on an Equiform Motion

In this paper we investigate a new type of ridges and ravines of the configuration space corresponding to an equiform motion in the Euclidean space R3. Necessary and sufficient conditions for the existence of generalized ridges and ravines are expressed as a partial differential inequalities involving the principal curvatures. For special case we obtain the solution of the differential equations which characterize some type of singularities. The singularities are displayed through figures [1, 2, 3].Key words Equiform motion; Configuration space; Generalized ridges and ravine

Local Study of Singularities on an Equiform Motion

In this paper we investigate the local singularities of the configuration space corresponding to an equiform motion in the Euclidean space $R^3$. The chaotic behavior of singularities are displayed through figures

An Integrated Inventory Production System In A Three-Layer Supply Chain

With growing focus on supply chain management, firms realise that inventories across the entire supply chain can be more efficiently managed through greater co-operation and better co-ordination. This paper deals with inventory and production coordination in a three-layer supply chain involving suppliers, manufacturers and retailers. Each stage may have more than one firm. It is assumed that the cycle time at each stage is an integer multiple of the cycle time of the adjacent downstream stage. In addition, the produced lot at each stage is sent to the adjacent downstream stage in equal shipments. Shipments are sent as soon as they are produced and there is no need to wait until a whole lot is produced. A cost minimisation model and its solution procedure are derived. A numerical example is presented for illustrative purposes. This policy leads to considerable savings as compared to the scheme that allows shipments only after the whole lot is produced

EVALUATION OF THE IMMUNE RESPONSE TO POLIO VACCINE IN MALNOURISHED CHILDREN IN SANA'A CITY

Objective: This study was made to evaluate the immune response to polio virus vaccine among PEM children by measuring the level of circulating Immunoglobulin G (IgG) antibodies against polio virus (IgG-PV) after immunization with the primary series of POV, and determining the coverage rate of universal childhood vaccine for polio virus. A cross-sectional laboratory study was conducted in Department of Medical Microbiology and Clinical Immunology, Faculty of Medicine and Health Sciences, and Al-Sabeen University Hospital, Sana’a University. Methods: A total of 279 PEM children were selected and investigated for universal childhood vaccination coverage rate for polio vaccine. Blood samples were collected from all, then tested for levels of IgG-PV by ELISA method. For assessment IgG-PV levels more than 10 units/ml were considered protected against polio virus infection. Results: The coverage rate of polio virus vaccine for first year vaccine was 96.8%; and 91.1% of vaccinated PEM children responded to the vaccine with mean level of 46.2 U/ml. A statistically significant difference was observed with respect to sero-protective IgG-PV between males and females (85.7% and 94.1% respectively, p=0.002); and older children (>37 months) (97.7%). Conclusion: We conclude that a small proportion of malnourished vaccinated children with a normal immune status were not serologically immune to polio virus infection, and remain to be reconsidered for either revaccination or booster doses due to lack of or inadequate response. PEM group gave slightly reduced response to OPV hence there is need to give this group IPV (injectable polio vaccine) along with OPV and different micro-nutrition deficiencies like Zinc and iron. Peer Review History: Received 29 March 2018;   Revised 20 April; Accepted 7 May, Available online 15 May 2018 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.

Underlying Primary Causes of Chronic Renal Failure: A Three-Year Study in Al-Thawra General Hospital, Sana'a, Yemen

Objective: To estimate the underlying primary diseases of chronic renal failure (CRF) among patients attending Al-Thawra General Hospital, Sana'a, and Yemen.Methods: This was a cross-sectional, hospital-based study of 566 patients diagnosed with chronic kidney diseases (CKD). It studied the cases attending Al-Thawra General Hospital over a three‐year period from January 2013 to December 2015.Results: Out of 566 patients, 339 (59.9%) were males. The mean age of the patients at diagnosis of CKD was 39.51 years, most of whom (36.6%) were of the age group of 21–35 years. Hypertension was the most frequent cause (43.2%) of CRF, followed by different infectious diseases such as malaria, schistosomiasis and bacterial infections (19%) and obstructive nephropathy (17.9%). On the other hand, CRF of unknown etiology represented 15.2% of cases. Other causes of CRF diabetic nephropathy (9.7%), effect of antibiotics and analgesics (7.0%), ischemic heart disease (4.8%, polycystic kidney disease (3.5%) and congenital anomalies (3.4%). The least common causes were autoimmune diseases, bleeding, traumatic accidents and chronic diarrhea, being responsible for 2.2%, 1.8%, 0.9% and 0.4% of CRF cases, respectively.Conclusions: The majority of CKD cases in our study were males aged between 21 and 35 years old. In addition, most cases of CKD are due to hypertension, followed by infections and obstructive nephropathy. Application of future prevention and control measures are highly recommended to reduce the burden of CRF in Yemen for early detection and proper management of its underlying primary conditions/diseases

Molecular detection of two virulence factors of Pseudomonas aeruginosa isolated from burn patients

The present study aimed to identify two virulence genes in P. aeruginosa isolated from infected burn wound. Out of 70 burn swabs, 54 (77%) showed positive growth on enriched media which obtained from burn wound at Al-Mussan Teaching Hospital in Mussan province, Iraq. Only 13 isolates (35%) identified as P. aeruginosa, and those isolates examined using Polymerase Chain Reaction (PCR) for detection the exoS and phzS genes. The results recorded that 46% and 77% of isolates have exoS, phzS genes, respectively. We concluded a P. aeruginosa harbor diverse percentages of both  genes as virulence factors, and those factors must be increased the pathogenicity of this pathogen
