Ivy City Community Development Project

Since January 2005, the Ivy City Community Development Project, led by sponsoring organization Empower DC, has worked to create an organization for the Ivy City community in Washington, DC, led by residents and stakeholders, to empower the community to control economic assets, to prevent the sale of their greatest public asset (Crummell School) and ensure its redevelopment, and to organize and develop capacity in the community to proactively address rapid gentrification. Grassroots organization Empower DC has led community organizing efforts and developed community capacity through conducting needs assessment and necessary trainings. In May 2005 residents and stakeholders brought together by Empower DC named the Historic Ivy City/Crummell School Revitalization Coalition (Ivy City Coalition for short), wrote its mission statement and established working committees to protect residents from the threat of displacement due to rising housing costs. Through the Ivy City Coalition, residents and stakeholders have greatly increased their civic participation and have exercised enormous influence on the course of decision making impacting the Ivy City community. In response to city-sponsored revitalization proposals, residents authored the Ivy City Plan for Home Again and established the Home Again/Ivy City Task Force which meets on a regular basis with the city to design the planned development of 60+ new housing units, which residents are pushing to be offered to very low-moderate income families with current residents receiving priority. The Ivy City Community Development Project will be evaluated based on: 1) The sustained involvement and leadership of residents and stakeholders 2) The successful completion of a revitalization plan for Ivy City 3) The successful negotiation of partnerships with District government, community developers and financial institutions to actualize the revitalization, and 4) Instituting measures of sustainability for the Ivy City Coalition.

A case report on dental management of a toddler with Pachygyria

Children with special health care needs receive less oral care than the normal population, inspite of the high level of dental diseases among them. They are at an increased risk for oral diseases throughout their lifetime. This paper reports a case of a toddler with congenital unusual thick convolutions of the cortex resulting in a condition called pachygyria. Intra oral examination showed multiple abscesses with poor oral hygiene. As the patient was lacking cooperative ability, treatment of full mouth rehabilitation as needed. The parents were advised for regular dental check-ups and informed about maintenance of good oral hygiene. This case report demonstrates the importance of oral hygiene maintenance of special children and also about their short and long term dental treatment protocol for maintaining good oral health

Experimental and numerical study of sluice gate flow pattern with non- suppressed sill and its effect on discharge coefficient in free-flow conditions

The purpose of this study is to investigate the flow pattern and discharge coefficient of sluice gate with the non-suppressed sill in experimental and numerical conditions. For this purpose, the sill of a rectangular cube in widths of 7.5, 10, 15, and 20 cm was installed under the sluice gate. Experimental results showed that placing a non-suppressed sill under the sluice gate by creating a failure in the flow lines causes a different flow pattern compared to the without sill state. Deviation of streamlines after colliding with the sill causes the formation of V-shaped currents. The discretization of equations for simulations were performed using VOF method. After selecting a cell with a size of 0.07 cm as the optimal cell, the RNG turbulence model was used. The results of the numerical simulation showed an acceptable agreement with the experimental results. Thus, the place of formation of V-shaped currents was transferred downstream of the sluice gate by increasing the width of the sill and the inflow discharge. The results of the study of the discharge coefficient showed that the placement of the sill with a width of 7.5 and 20 cm, increased the discharge coefficient by an average of 5.3% and 15.5% in the experimental model and 4.7% and 16% in the numerical simulation. This relationship is without sill state and with sill state with root mean square error of 0.967 and 0.968, respectively, estimated the discharge coefficient of the sluice gate

A comparative evaluation between cheiloscopic patterns and the permanent molar relationships to predict the future malocclusions

Background: To assess the correlation between different cheiloscopic patterns with the permanent molar relationships. Material and Methods: 300 children who are 14-16 years old with completely erupted 2nd permanent molars upto occlusal table were recruited and the pattern of molar terminal plane was recorded in the proforma. Lip prints of these subjects were recorded with lipstick-cellophane method and middle 10mm of lower lip was analysed for the lip print pattern as suggested by Sivapathasundharam et al. The pattern were classified based on Tsuchihashi and Suzuki classification. Results: Type II (branched) pattern was the most predominant cheiloscopic pattern. The predominant patterns which related to the Angle?s classification were; type I (complete vertical) pattern for class I, type IV (reticular) pattern for class II and presence of type IV (reticular) pattern and absence of type I? (incomplete vertical) pattern for class III. In class III molar relationship, males showed an increased type II (branched) pattern and females showed an increased type IV (reticluar) pattern. Conclusions: Lip prints can provide an alternative to dermatoglyphics to predict malocclusions in permanent dentition. Further studies with larger sample size are required to provide an insight into its significant correlations

A comparative evaluation between dermatoglyphic patterns and different terminal planes in primary dentition

To assess the correlation between different dermatoglyphic patterns with the terminal planes in deciduous dentition. 300 children who are 3-6 years old with complete primary dentition were recruited and the pattern of molar terminal plane was recorded in the proforma. Finger prints of the distal phalanges of these subjects were recorded using ink and roller method and were analysed for the finger print pattern by a forensic specialist. The pattern were classified based on classification given by Galton. The finger ridge counts were also measured. Ulnar loop pattern was the most predominant dermatoglyphic pattern. Absence of arch pattern in ring and little fingers of left hand and higher ridge count in left little finger when compared to the right hand were related to Mesial step. Presence of whorl pattern in both right and left middle finger and higher total finger ridge count in left hand when compared to the right hand were related to distal step. Flush terminal plane was related to absence of arc pattern in ring finger of left hand. Dermatoglyphics can be used as a non invasive analytical tool to predict the terminal plane in primary dentition

Numerical Investigation on Effective Parameters on Hydraulic Flows in a Sluice Gate with Sill on Free-Flow Condition

The presence of a sill under the sluice gate is one of the solutions to control the flow rate. This study was conducted to numerically investigate the discharge coefficient (Cd) of sluice gates with different heights and widths of sills in free flow conditions. The simulations were performed using FLOW-3D software. Results show that Cd increases as the gate opening decreases. Also, results showed that reducing the gate opening from 5 cm to 2 cm increases the Cd in the gate with sill by 9% compared to the non-sill gate. Discharge coefficients with 1 cm and 4 cm sills, compared to the non-sill condition were estimated at 1.5% and 18%, respectively. Examination of sill width changes showed that decreasing the width reduces the discharge coefficient by reducing the amount of velocity and flow pressure along the sill sides. The effects of three parameters of the gate opening, sill height, and sill width were compared. The results showed that increasing the sill width compared to the two mentioned parameters has the maximum increase in the Cd

Effect of protective coating on microleakage of conventional glass ionomer cement and resin-modified glass ionomer cement in primary molars: An In vitro study

Aim: The aim of this in vitro study was to evaluate and compare the effect of protective coating G-Coat Plus on microleakage of conventional glass ionomer cement (CGIC) and resin-modified glass ionomer cement (RMGIC) in primary molars. Materials and Methods: A total of 120 samples were divided into four groups with 30 samples in each group. Group A – teeth restored with CGIC. Group B – teeth restored with CGIC coated with G-Coat Plus. Group C – teeth restored with RMGIC. Group D – teeth restored with RMGIC coated with G-Coat Plus. Microleakage was tested using 2% basic fuschin dye penetration and measured at ×40 original magnification under the stereomicroscope. Results: The results of this in vitro study showed that coating with G-Coat Plus showed a reduction in microleakage in CGIC and complete absence of microleakage in RMGIC when compared to the noncoated groups, which was statistically significant. CGIC without G-Coat Plus showed highest microleakage followed by RMGIC without G-Coat Plus, followed by a relatively less microleakage in CGIC with G-Coat Plus. Conclusion: Significant reduction in microleakage was seen in conventional GIC and RMGIC with G-Coat Plus when compared to conventional GIC and RMGIC without G-Coat Plus

A comparative evaluation between cheiloscopic patterns and terminal planes in primary dentition

Objective: To assess the correlation between different cheiloscopic patterns with the terminal planes in deciduous dentition. Materials and Methods: Three hundred children who are 3–6 years old with complete primary dentition were recruited, and the pattern of molar terminal plane was recorded in the pro forma. Lip prints of these children were recorded with lipstick-cellophane method, and the middle 10 mm of lower lip was analyzed for the lip print pattern as suggested by Sivapathasundharam et al. The pattern was classified based on Tsuchihashi and Suzuki classification. Results: Type II (branched) pattern was the most predominant cheiloscopic pattern. The predominant patterns which related to the terminal planes were as follows: Type IV (reticular) and Type V (irregular) pattern for mesial step, Type IV (reticular) pattern for distal step, and Type I (complete vertical) pattern for flush terminal plane. No significant relationship was obtained on gender comparison. Conclusion: Lip prints can provide an alternative to dermatoglyphics to predict the terminal plane in primary dentition. Further studies with larger sample size are required to provide an insight into its significant correlations

Experimental Study of Geometric Shape and Size of Sill Effects on the Hydraulic Performance of Sluice Gates

The present research was conducted to investigate the effect of sill geometry and sill width on the discharge coefficient and hydraulic jump characteristics. For this purpose, sills with semi-cylindrical, cylindrical, pyramidal, and rectangular cube geometries with widths of 0.075, 0.10, 0.15, and 0.2 m were installed under a sluice gate. Results showed that increasing the sill width increased the sluice gate discharge coefficient compared to the no-sill mode. The results of placing a sill with different geometric shapes under a sluice gate indicate that using a semi-cylindrical sill increases the discharge coefficient. The ranked order of other sills, from the largest to smallest discharge coefficient, is: cylindrical, pyramidal, and rectangular cubic sills, respectively. The results show that the use of a sill increases the energy dissipation. Examining sills of different widths indicates that with increasing width, the increase in velocity and consequent decrease in the depth of the hydraulic jump causes an increase in energy loss. When employing sills of maximum width (b = 0.20 m) for pyramidal, semi-cylindrical, cylindrical, and rectangular shapes, the energy loss increased by 125, 119, 116, and 125% in section A, respectively. The semi-cylindrical sill is most effective in increasing the discharge coefficient, while the pyramidal sill is most effective for increasing energy dissipation
