An analysis of the 1948 Jersey heifer registration data to provide information concerning some features of New Zealand pedigree Jersey cattle

At present there is a lack of information concerning the breeding methods practised by owners of pedigree dairy cattle in New Zealand. This deficiency is a serious handicap in attacking some of the major problems facing the dairy industry in this country. Since the emergence of the Dairy Board in 1936 as the main national force concerned with herd improvement a great deal has been achieved in the field of dairy cattle improvement and the evolution of a sire survey applicable to conditions obtaining in New Zealand is one of the major achievements of the Dairy Board. But many aspects of the pedigree industry which provides the majority of sires used in the Dominion remain to be elucidated. For example, the present scarcity of proven sires, and the more or less stationary level of production of commercial herds are some of the problems which have direct bearing on the pedigree section of the dairy industry. These facts alone illustrate the importance of the study of current breeding methods and of the pedigree system as it exists in New Zealand. Many investigations relating to dairy cattle breeding have been carried out overseas. Although many of the problems studied are encountered in New Zealand, the Dominion's typical grassland farming and the seasonal dairying associated with it limit the usefulness of such investigations. With more information becoming available breed societies are beginning to adjust themselves to a new phase of cattle breeding. The increasing emphasis on production as an aid to selection, and the acceptance of artificial insemination are two phases in which a change of attitude is desirable. The rapid growth of pedigree herds, the more frequent appearance of performance details in pedigrees and the increasing number of pedigree animals mated artificially each year illustrate this gradual change

Successful management of a supralevator intraperitoneal puerperal hematoma with angiographic embolization

Puerperal hematomas are rare, yet often life threatening, complications following vaginal deliveries. The etiology remains broad; however, early recognition is vital in preventing postpartum hemorrhage and maternal death. Our case illustrates treatment of a supralevator hematoma with angiographic embolization following a spontaneous vaginal delivery in a young woman. Her labor course was complicated by persistent occiput posterior presentation that failed spontaneous and manual rotation

Effect of one-year corrosion on steel bridge materials in the maintenance stage with the Charpy impact test method

Corrosion of steel bridges is a major problem because it has the potential to reduce the performance of the structure over its lifetime. One factor that should not be reduced is fracture toughness, so this should be a very important concern in the maintenance program. Existing guidelines do not specify when corrosion conditions are hazardous and when corrosion conditions are not hazardous to structural performance. This study aims to explain how long corrosion does not cause danger, and when corrosion becomes dangerous. The Charpy Impact Test was used in this study to examine the effect of corrosion with a corrosion duration of weekly up to one year on fracture toughness. The series of tests in this research program used SM-490-type specimens which are steel plates commonly used for bridge structures. Specimens with variations in corrosion duration which were the result of immersion in sulfuric acid solution to simulate corrosion growth were then subjected to crack toughness testing. The toughness of each specimen was tested with a corrosion period starting from 1 week and so on up to 1 year to determine the level of fracture toughness. The results obtained from all tests showed that there was no decrease in the toughness of the corroded specimens for up to 1 year. The data presented in this study is very helpful for the designers and maintainers to plan corrosion treatment programs with clearer and more accurate considerations in assessing the structural integrity of steel bridges affected by corrosion

The law pertaining to white collar crime in Malaysia: a study on its enforcement / Mohamad Amir Ardzhar Fahimuddin … [et al.]

The purpose of this study is to analyze the law pertaining to white collar crime in Malaysia with specific reference to Malaysian Anti-Corruption Commission Act 2009 (the Act) in dealing with the offences of white collar crime in the nation. The practices of white collar crime are remained rampant despite the efforts done by the Malaysian Anti-Corruption Commission (the Commission). Malaysia as a nation strives on the vision to create an environment that is harmonious, united, constantly developing and of the high integrity. Such nation breeds communities that uphold dignity and performs the duties and responsibilities with high disciplines and dedication. Since decades, these fundamental elements have lost its grip that had led to a concern that has caused economic losses running billions and destroying the very basis of humanity and integrity. The act of white collar crime has long been a concern and its consequences leads to the destruction of the mortar that grips our economics. White collar crime also had created major imbalances in the economic, political and social strata. The unearthing of greed and selfishness, disrespect and disregard for policies and procedures and the blinding of transparency, results in the nation with low integrity. On the other hand, corruption involves not only middle class society but also higher ranking person in the society. Therefore, this research seeks propose a viable solution where affected parties can be protected and the corrupt be brought to justice

Granting specificity for breast cancer cells using a hepatitis B core particle with a HER2-targeted affibody molecule

Capsid-like particles consisting of a hepatitis B core (HBc) protein have been studied for their potential as carriers for drug delivery systems (DDS). The hollow HBc particle, which is formed by the self-assembly of core proteins comprising 183 aa residues, has the ability to bind to various cells non-specifically via the action of an arginine-rich domain. In this study, we developed an engineered HBc particle that specifically recognises and targets human epidermal growth factor receptor-related 2 (HER2)-expressing breast cancer cells. To despoil the non-specific binding property of an HBc particle, we genetically deleted the C-terminal 150–183 aa part of the core protein that encodes the arginine-rich domain (ΔHBc). Then, we genetically inserted a ZHER2 affibody molecule into the 78–81 aa position of the core protein to confer the ability of target-cell-specific recognition. The constructed ZHER2-displaying HBc (ZHER2-ΔHBc) particle specifically recognised HER2-expressing SKBR3 and MCF-7 breast cancer cells. In addition, the ZHER2-ΔHBc particle exhibited different binding amounts in accordance with the HER2 expression levels of cancer cells. These results show that the display of other types of Affibody molecules on HBc particles would be an expandable strategy for targeting several kinds of cancer cells that would help enable a pinpoint DDS

Cocoa Pod Husk Biochar Reduce Watering Frequency and Increase Cocoa Seedlings Growth

Biochar amount applied in the growing soil medium may decrease water use of cocoa seedling during dry season and hence may increase water use efficiency, thus a polybag experiment was carried out in the Glasshouse Agricultural Faculty, Halu Oleo University, Kendari, Southeast Sulawesi Indonesia in 2016to evaluate the effect of cocoa pod husk (CPH) biochar and watering frequencies on growth of cocoa seedlings.The experiment was arranged in a randomized block design with seven cacao pod husk (CPH) biochar levels (without CPH biochar, 3 g CPH biochar kg-1 soil, 6 g CPH biochar kg-1 soil, 9 g CPH biochar kg-1 soil, 12 g CPH biochar kg-1 soil, 15 g CPH biochar kg-1 soil dan 18 g CPH biochar kg-1 soil) and three watering frequencies ( every two days, every four days and every six days) in three replications. Results showed that CPH biochar and watering frequency significantly influenced soil moisture. The rate of CPH biochar amendment determined watering frequency and cocoa seedling growth rate. CPH biochar improved cocoa seedling growth and reduced watering frequency. Cocoa seedlings treated with 9 g CPH biochar kg-1 soil and 60 g CPH biochar kg-1 soil with every six days of WF increased WUE by 208.8% and 262.22%, respectively, compared to no biochar application

Development of biodegradable sustained-release damnacanthal nanocapsules for potential application in in-vitro breast cancer studies

The “noni” species of Morinda citrifolia L., is using in traditional medicine in the tropical country for over 2000 years. Noni fruit has come from the Morinda citrifolia tree which is called Rubiaceae, and it is from the coffee family. It is a perennial herb whose ripe fruit has a robust butyric acid smell and flavor. Recently scientists have proven that this fruit has antioxidant and antibiotic properties in vitro. An anthraquinone, damnacanthal, is one of the constituents of Morinda citrifolia. It has been demonstrated to have anti-cancer properties. Damnacanthal has low water solubility and low bioavailability. Formulating of damnacanthal into the biodegradable nanocapsule drug delivery system may increase its bioavailability. Various formulations of damnacanthal would be developed to enable the selection of a dosage form that could offer the provision of the anti-cancer bioactive substance with suitable sustained- or controlled release properties. The efficiency of extraction of damnacanthal will be compared using both conventional and traditional method. Both the damnacanthal and an anthraquinone active compounds extracted from noni roots, are currently being studied in the context of anti-cancer study. Soon, the medical values, bioactivities and nutritional of this fruit can be assessed, especially its anti-cancer activity, this fruit extract could play an outstanding economic role in Malaysia and other tropical countries

Poly lactic-co-glycolic acid nanoparticles: flow rates and gauge sizes influence the droplet surface tension and particle sizing

Electrospray is a novel and versatile approach to the synthesis of nanosized particles. In this paper, the effects of electrospray process parameters such as gauge size (18 G-25 G) and flow rate (0.9-1.5 ml hr-1) on droplet surface tension and electrospray particle size were evaluated. 25 mg Poly Lactic-co-Glycolic Acid (PLGA) were dissolved in 100 ml acetone before being subjected to electrospray. Tate’s Law was used to calculate the surface tension while the Malvern nanosizer was used to measure the particle size. Based on Tate’s Law calculation, when the gauze size increased from 18 G-25 G, the droplet surface tension increased from 10.07 Nm-1 to 18.17 Nm-1 showing a direct pattern. At the same time, the flowrate is inversely proportional to droplet surface tension. When the flow rate increased from 0.9-1.5 ml hr-1, the droplet surface tension was reduced. This is due to the increasing ratio of vicious force and surface tension. For particle size, as surface tension increased from 10.07 Nm-1 to 18.17 Nm-1, particle size increased from 205.57 nm to 612 nm owing to the corona discharge producing larger progeny droplets that chain into smaller particles through coulomb fission as more charge is required to overcome the surface tension. In conclusion, flow rate and gauge size influenced the surface tension thus affecting the nanosized particles
