Management and control of coccidiosis in poultry - A review
Rafiq Ahmad,Yu-Hsiang Yu,Kuo-Feng Hua,Wei-Jung Chen,Daniel Zaborski,Andrzej Dybus,Felix Shih-Hsiang Hsiao,Yeong-Hsiang Cheng Asian Australasian Association of Animal Productio 2024 Animal Bioscience Vol.37 No.1
Poultry coccidiosis is an intestinal infection caused by an intracellular parasitic protozoan of the genus Eimeria. Coccidia-induced gastrointestinal inflammation results in large economic losses, hence finding methods to decrease its prevalence is critical for industry participants and academic researchers. It has been demonstrated that coccidiosis can be effectively controlled and managed by employing anticoccidial chemical compounds. However, as a result of their extensive use, anticoccidial drug resistance in Eimeria species has raised concerns. Phytochemical/herbal medicines (Artemisia annua, Bidens pilosa, and garlic) seem to be a promising strategy for preventing coccidiosis, in accordance with the "anticoccidial chemical-free" standards. The impact of herbal supplements on poultry coccidiosis is based on the reduction of oocyst output by preventing the proliferation and growth of Eimeria species in chicken gastrointestinal tissues and lowering intestinal permeability via increased epithelial turnover. This review provides a thorough up-to-date assessment of the state of the art and technologies in the prevention and treatment of coccidiosis in chickens, including the most used phytochemical medications, their mode of action, and the applicable legal framework in the European Union.
Analysis of Tool Wear by Using a Cutting Bending Moment Model for Milling Processes
Hsiang-Chun Tseng,Meng-Shiun Tsai,Bu-Ci Yeh,Kuan-Ming Li 한국정밀공학회 2022 International Journal of Precision Engineering and Vol.23 No.8
In this study, we developed a bending moment model that considers the cutting forces acting on a sensory tool holder along the rotational direction. The polar plot of the bending moment during cutting can be used to investigate the cutting behavior. Cutting processes with different cutting depths and widths result in different polar plots, as verified experimentally. To evaluate the effect of tool wear on the polar plot, the bending moment equations were modified to incorporate the developed tool wear model. The simulation results indicated that tool wear can increase the size of the polar plot and vary the angle of the plot. By examining the change of this angle, one can determine the level of tool wear. The experimental results of this study indicated that the derived equation can predict the tool wear behavior with an average accuracy of 84%. Thus, the proposed integrated model enables the accurate prediction of tool wear. Consequently, the polar plot can feasibly be used to detect the level of tool wear.
Mandarin Bare Classifier-Nouns: Towards a Universal Structure for Classifiers and Plurals
Hsiang-Hua Chang 세종대학교 언어연구소 2014 Journal of Universal Language Vol.15 No.1
Mandarin, as other classifier languages, usually requires a classifier when numerals, quantifiers, or demonstratives are present, but also allows bare classifier-nouns (CL-N) without any determiners. This paper examines two empirical questions: (i)What is the structure of CL-N that can account for its behavior? (ii) Under what conditions are bare CL-Ns acceptable? Following Borer’s Exo-Skeletal framework, I draw a parallel between Mandarin classifiers and the English plural. Mandarin ben shu‘CL book’ and English books both are CLASSIFIER PHRASES carrying no quantity information. Numeral-classifier-nouns (Num-CL-Ns), such as san ben shu ‘three books,’ are QUANTITY PHRASES carrying quantity information. This proposal correctly predicts that CL-Ns and Num-CL-Ns have different distributions due to different structures. Supporting data are drawn from CL-Ns in argument and non-argument positions in various constructions to attest the prediction that when the quantity information is needed in the discourse, Num-CL-Ns will be obligatory; in contrast, when the quantity information is not crucial, CL-Ns will be preferred or obligatory.
Intentional Identity Revisited
Hsiang-Yun Chen 서울대학교 철학사상연구소 2017 철학사상 Vol.S No.-
The phenomenon of intentional identity has bemused philosophical communities since Geach (1967). I argue that the phenomenon is ubiquitous and much more significant than previously acknowledged. The foundations of the problem are implicated in many other well-known puzzles, such as Kripke’s (1979) puzzles about beliefs. Thus, the need for a proper analysis is eminently pressing. I specify a template for generalizing intentional identity, identify the challenges involved, and argue that positing a level of representational entity in both philosophy of mind and language (e.g., mental files) is a promising approach to tackling the problem across the board.
Rapid screening of roundup ready soybean in food samples by a hand-held PCR device
Hsiang-Yun Tung,Sue-Hong Wang,Yu-Cheng Chiang,Ming-Shiun Tsai 한국식품과학회 2016 Food Science and Biotechnology Vol.25 No.4
Insulated isothermal PCR (iiPCR) method was recently available for rapid on-site detection ofroundup ready soybean (RRS; event GTS40-3-2) in food materials and products. Performance of thismethod was evaluated in this study. The 100% detection endpoint for the RRS by iiPCR was found insamples containing 0.1% RRS, equivalent to the results of the reference real-time PCR (rtPCR). Analysisof nucleic acids of soybean-based processed food products indicated 95% agreement between the iiPCRand rtPCR for RRS detection. By testing soybean milk and tofu samples using simple pretreatmentmethods, we found that the agreements between iiPCR and rtPCR methods of the aforementionedsamples were 80% and 90%, respectively. Replicated tests of all discrepant samples implied that thesesamples had trace amounts of RRS, suggesting that the iiPCR system is more sensitive than the rtPCRmethod. In conclusion, the iiPCR technology can be a useful point-of-need tool to help make a timelydecision in the consumption of genetically modified organisms.

Aim(s): Nurse aides provide a major support for long-term care services. However, research findings regarding the various aspects of nurse aides’ work competence that may facilitate or impede their work performance remain inconsistent. To compare th-e differences between the nurse aides’ and registered nurses’ perceptions of the nurse aides’ work competence. Method(s): This study was designed as a cross-sectional study, and convenience sampling w-as employed to recruit a sample that comprised 220 nurse aides and registered nurs-es who had served for more than three months at a regional teaching hospitalin southern Taiwan. The instruments consisted of the demographic data and the 36-it-em Nurse Aides’ Work Competence Scale. Result(s): There are no significant differences between the self-perceived and the nurse-s’ reported overall work competence of nurse aides. The results showed that th-e nurse aides had room for improving their work competence in terms of “pro-blem solving” and “activity design”. The nurse aides and resisted nurses differe-d significantly in terms of “activity design” because the nurse aides’ perception of their work competence in “activity design” was more positive than that repo-rted by the registered nurses. Conclusion(s): Nurse aides should be incorporated into cross-disciplinary teams. Activity design could be handled by other healthcare providers such as physical therapists or senior social workers.
