vaccination considered as one of the most cost-effective health interventions worldwide  through prevention and control of many serious childhood diseases (1). it is estimated  global coverage of  dose 3 of diphtheria, tetanus, and pertussis (dtp3)among children one year old has been 86% in 2014 (by range from 77% to 96%  in african region and western pacific region; respectively) (2). globally...

in 1974, the world health organization (who) established the expanded program on immunization (epi) to ensure that all children have access to routinely recommended vaccines. since then, global coverage with the four core vaccines (bacille calmette guérin vaccine [for protection against tuberculosis], diphtheria-tetanus-pertussis vaccine [dtp], polio vaccine, and measles vaccine) has increased ...

The fracture and crack growth of mechanical structures is a usual phenomenon which is due to the application of tensile, cyclic loading or thermal stresses on the structure. So introducing of methods to prevent the crack growth is useful. Afterward, one of the repairing methods of crack growth, consisting to make a hole in the crack tip to elimi-nate the sharp corners, was explained. This metho...

adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...

When testing software, testers rarely use only one technique to generate tests that, they hope, will fulfill their testing criteria. Malaiya showed that testers switch strategies when testing yield saturates. We present and evaluate a stopping rule that can be used to determine when it is time to switch to a different testing technique, because the current one is not likely to increase criteria...

Linked faults are very important for memory testing because they reduce the fault coverage of the tests. Their analysis has proven to be a source for new memory tests, characterized by an increased fault coverage for a given test time. This paper presents an analysis of linked faults, based on the concept of fault primitives, such that the whole space of linked faults is investigated, accounted...

Abstract Various climbing plants can be selected as an element in the vertical greenery system. However, it should consider species’ suitability to climb any structure. This study aims analyze growth rates of several a plane at different hole sizes wire mesh. The experimental design used this experiment was split-plot factorial randomized block that consisted two factors with three replications...

The paper aims to put in the forefront a survey on problem of existing holes Wireless Underground Sensor Networks (WUSNs). Anomalies wireless sensor networks can weaken network by impeding its functionalities. These anomalies commonly known as may cause irreversible devastating problems and prove fatal humans. There be different network, such coverage hole, routing jamming sink/ worm etc. This ...

Among other things, the modern game of football is characterised by pronounced group and team-oriented tactical abilities. Of particular importance is thereby zone defence or zone coverage, which is used by almost all teams playing at an elevated level of performance. In contrast to man-marking, this more efficient form of organisation is very difficult to convey, as attention must at any given...
