Water hyacinth (Eichhornia crassipes (Mart.) Solms) is a prolific free floating aquatic macrohpyte found in tropical and subtropical parts of the earth. The effects of pollutants from textile wastewater on the anatomy of the plant were studied. Water hyacinth exhibits hydrophytic adaptations which include reduced epidermis cells lacking cuticle in most cases, presence of large air spaces (7 approximately 50 microm), reduced vascular tissue and absorbing structures. Textile waste significantly affected the size of root cells. The presence of raphide crystals was noted in parenchyma cells of various organs in treated plants.

For the development of 19-plex Y STR system and polymorphism studies in locl ethnic populations sixteen markers of non-recombining regions (NRY) of Y chromosome, which show high power of discrimination among individuals, were selected in this study. Blood samples (600) were e.ollected from the males of three most common castes of Pakistani population (Arnin, Awan and Rajput) with different parent lineages. Three markers (DYS385a/b, DYS389Ⅰ/Ⅱ and YCAⅡa/b) among 16 Y STRs are double-targeted regions of the Y chromosome and thus provide two polymorphie peaks for each respective primer set. These 16 Y-STRs were developed into Megaplex system for simultaneous amplification of all markers within the population. The overall power of discrimination observed in focused populations was 60.5%, 66.5% and 55% in Rajput, Awan and Arain casts respectively. This discrimination power will be helpful in haman identification for forensic casework studies including sexual assaults and paternity testing.

The aim of this study was to identify factors that affect the dental service delivery in a dental clinic from the context of Papua New Guinean dental providers and to make practical recommendations to improve dental service delivery. This qualitative descriptive study used individual interviews with seven dental providers to identify the factors that were affecting quality dental service delivery in a dental clinic in Papua New Guinea. The factors influencing the quality of dental service fell into three categories and 8 themes. The categories were environmental factors with themes of resources and facilities, leadership and management, partnership development and collaboration; provider-related factors with themes provider competence, provider motivation and satisfaction; and required measures with the themes of a new dental clinic building, renovation of the main clinic area and organizational structure. Quality dental service is achieved when there is a supportive working environment with availability of (new) physical amenities and dental resources, and proper management and organizational structures with supportive visionary leadership. This would encourage teamwork and partnership development internally within the dental team and externally with its stakeholders. Furthermore, it would increase staff motivation and satisfaction internally and partnership development internally within the dental staff and externally with its stakeholders. Consider creating a new dental clinic. Develop a contract between the University and the Hospital to resolve the property ownership issues. Create a clear organizational structure and improve management interaction with clinical staff so that management is supportive. Improve the quality of dental supplies and create an efficient material ordering system. Ensure fairness to staff and respect to procedures are compliantly maintained to encourage teamwork. Reward clinical staff for mentoring and teaching dental students. Create access to continuing professional development for the clinical staff.
