Las enfermedades negligenciadas son un gran problema de la salud pública, especialmente para la población más pobre de la sociedad, en la que las enfermedades parasitarias tienen un destaque. El suelo desempeña un papel fundamental para mantener la existencia de estructuras durante un prolongado período de tiempo, lo cual posibilita las infecciones. El propósito del presente artículo consistió en evaluar la presencia de estructuras parasitarias en el suelo de las áreas de recreación de Maceió, Brazil, así como realizar un análisis detallado de las especies patogénicas. Un total de 42 muestras del suelo fueran colectadas de las localizaciones de recreación, con 21 de la superficie y 21 de la profundidad. Las muestras fueron separadas, nombradas, guardadas y transportadas para los análisis en el laboratorio. Haciendo el procesamiento parasitológico por el método de HPJ (Hoffman, Pons y Janner) y el método de Ritchie para posterior observación en lámina coloreada con lugol en microscopio. De las muestras, 34 (80,95%) fueron positivas, ocurriendo el multiparisitismo, con los helmintos en mayores cuantidades (74,22%). La investigación ha revelado qué todas las ubicaciones de recreación estaban contaminadas con helmintos y protozoarios. Acerca de la profundidad, las muestras de la superficie han estado más contaminadas, con 18 (52,94%) de todas las muestras analizadas. La especie principal encontrada fue Strongyloides stercoralis, con 28,86% de positividad en las muestras. En conclusión, esta investigación ha sugerido que las muestras del suelo sirven como un resumen para la presencia de infecciones zoonóticas, visualizando la necesidad de medicinas profilácticas químicas en el suelo, además, la aplicación de más investigación estandarizada por los organismos públicos.
Мектептердің өзін-өзі бағалауы арқылы білім берудегі өзгерістерді басқару

The Education Bureau in Hong Kong has implemented a two-pronged approach to assuring the quality of education: an external mechanism via inspection and an internal framework via self-evaluation. This paper reviews the quality assurance movement in Hong Kong and examines the characteristics of school selfevaluation and its relationship with change in education. Because change is a complex and dynamic process and difficult to initiate by acting on a single front, it is suggested that a “cocktail approach” of change leadership in education should be adopted to help overcome the resistance to change, afflicting the implementation of school self-evaluation.
Гонконгтың білім беру бюросы білім беру сапасын қамтамасыз етудің екі жақты тәсілін енгізді: тексеріс арқылы сыртқы механизмді қолдану және өзін-өзі бағалау арқылы ішкі құрылымды анықтау. Бұл мақалада Гонконгтағы сапаны қамтамасыз етуге бағытталған іс-шаралар, мектептегі өзін-өзі бағалаудың ерекшеліктері мен оның білім берудегі өзгерістермен байланысы қарастырылады. Өзгеріс бір бағытта әрекет ете отырып бастамашылық ету күрделі әрі динамикалық процесс болғандықтан, мектептегі өзін-өзі бағалауды енгізуге кедергі келтіретін қарсыластықты жеңуге көмектесу үшін білім берудегі өзгерістерді басқаруға «коктейль» тәсілін қолдану ұсынылады.
Бюро образования Гонконга внедрило двухсторонний подход к обеспечению качества образования: использование внешнего механизма путём инспектирования и определение внутренней структуры путём самооценивания. В данной статье рассматриваются движение за обеспечение качества в Гонконге, особенности школьного самооценивания и их связь с изменениями в образовании. Поскольку изменения – это сложный и динамичный процесс, который трудно инициировать, действуя в одном направлении, предлагается использовать «коктейльный подход» к руководству изменениями в образовании, чтобы помочь преодолеть сопротивление переменам, мешающим внедрению школьного самооценивания.

Pakan ternak babi di Kampung Sairo yang biasa diberikan hanya berupa kangkung dan daun ubi jalar. Sumber-sumber pakan lain seperti ampas tahu, jagung, dan kedelai sebagai nutrisi tambahan bagi pertumbuhan ternak belum banyak dimanfaatkan oleh peternak di kampung Sairo. Pemberian pakan yang berkualitas seperti pakan komersial menjadi pertimbangan karena harganya yang mahal. Oleh karena itu perlu dilakukan kegiatan penyuluhan pada masyarakat kampung Sairo terkait penyusunan pakan yang baik untuk babi sesuai fase pertumbuhan. Penyuluhan dilakukan dengan metode ceramah dan diskusi pada 22 peserta yang hadir. Materi penyuluhan disusun berdasarkan pustaka-pustaka yang relevans dengan pakan babi.. Hasil penyuluhan menunjukkan bahwa antusiasme peserta terhadap kegiatan penyuluhan tinggi dengan beragamnya pertanyaan yang diajukan. Kulit keladi, limbah sayur dan limbah warung makan yang ditemukan di kampung Sairo dan sekitarnya dapat dijadikan bahan-bahan pakan babi untuk semua fase. Bahan pakan lain seperti ampas tahu, limbah ikan, kulit kedelai dapat diperoleh di tempat lain di luar kampung Sairo namun mudah ditemukan di Kabupaten Manokwari.

Long-Term Effect of Rice and Non-rice Ecology on Pools of Carbon in Surface and Deep Soil in Farmer’s Field
Authors: Kumar Kolagani Hari , Kundu M. C. 
Published: April 2024

The greatest terrestrial sink of carbon (C) is soil. In addition to improving soil quality, carbon absorption in soil helps reduce atmospheric CO2 loading. Not only the surface soil, but also the deep sub-soil act as a storehouse of C. Besides, the study of C dynamics in tropical rice soil is important in countries like India where rice is the predominant crop and soil C sequestration is at risk due to high temperatures. In this context, this study tried to understand the C dynamics in surface as well as deep soil under rice and non-rice ecology. Representative soil samples were collected from five sites of rice-rice (rice ecology) and vegetable-vegetable (non-rice ecology) cropping systems from three depths viz., 0-20 cm, 100-120 and 120-140 cm from long-term farmer’s field of Nadia district of West Bengal belonging to Alfisols to compare C dynamics of surface and deep soils as well as rice and non-rice ecology. Results indicated that surface soils exhibited higher amount of total C, total organic C and inorganic C in comparison to deep soil irrespective of crop ecologies. The rice ecology showed higher total C and total organic C in comparison to non-rice soil. As per water solubility, water-soluble (room temperature) C and hot water-soluble C which were highest in surface soil compared to deep soil as the former usually receives maximum amount of fresh C input compared to deep soil. Irrespective of crop ecology, water-soluble C (WSC), hot water-soluble C (HWC), recalcitrant C (RC) were highest in surface soil compared to deep soils. Again, irrespective of soil depth, WSC and RC were highest in rice ecology and lowest in non-rice ecology. But, HWC content was highest in non-rice ecology and lowest in rice ecology. Irrespective of crop ecology, per cent contribution of labile pool of C (WSC+ HWC) and that of RC pool towards TOC was the highest and the lowest respectively. However, irrespective of soil depth, per cent contribution of labile pool of C and that of recalcitrant pool of C towards TOC was highest and lowest in soils under non-rice ecology and rice ecology respectively. Thus, this study conclusively indicated the potential of subsoil layer to act as a C sink in comparison to surface soil. The rice soil also has been identified as a niche for soil C sequestration.

The present study highlights the Integrated crop management in brinjalfor their yield and economics. A field experiments was in tiruvallur district of ICAR-Krishi Vigyan Kendra during 2017-2018. The implementation of scientific technology through optimal resource utilization is the primary driver for horticulture's development. Due to a lack of acceptance of cutting-edge technologies, low production is one of the main obstacles facing conventional brinjal cultivation. Frontline demonstration's primary goals were to persuade farmers to adopt brinjal production technologies in order to facilitate the wider spread of newly released crop production, protection, and management practices in their fields and farming situations, as well as to demonstrate these technologies in action. To increase the production, productivity and quality of agricultural produce, front line demonstrations are being conducted at various farmer’s field. There was significantly increased in brinjal yield (36.7 per cent), net return and B:C ratio after conduct of frontline demonstrations as compared to farmers practice. The adoption and implementation of integrated crop management practices through FLD programme, showed positive impact on brinjal growth, yield and economics.
Demonstration plot recorded higher technology gap (22.0 t/ha), extension gap (6.0 t/ha) and technology index (36.6 per cent), compare to local variety and also showed high percentage yield increase over farmer’s practice and recorded 20 per cent increase yield means technology was accepted by the farmers.As a result, 50 farmers initiated the small scale farming of brinjal in the district with the technical guidance provided from ICAR-KVK, Tirur, Tiruvallur. Therefore, a study on effect of integrated crop management practices on yield and economics of Brinjal in Tiruvallur district of tamilnadu was conducted during 2017-18.

AbstractThis paper reports on the degradation and protein release behavior of a self‐assembled hydrogel system composed of β‐cyclodextrin‐ (βCD) and cholesterol‐derivatized 8‐arm star‐shaped poly(ethylene glycol) (PEG8). By mixing βCD‐ and cholesterol‐derivatized PEG8 (molecular weights 10, 20 and 40 kDa) in aqueous solution, hydrogels with different rheological properties are formed. It is shown that hydrogel degradation is mainly the result of surface erosion, which depends on the network swelling stresses and initial crosslink density of the gels. This degradation mechanism, which is hardly observed for other water‐absorbing polymer networks, leads to a quantitative and nearly zero‐order release of entrapped proteins. This system therefore offers great potential for protein delivery.

Published: July 2009

AbstractOrdered mesoporous rutile and anatase TiO2samples are prepared using mesoporous silica SBA‐15 as template and freshly synthesized titanium nitrate and titanium chloride solutions as precursors. The rutile material formed from the nitrate solution is monocrystalline and contains minimal amounts of Si with a Si:Ti ratio of 0.031(4), whereas the anatase material formed from the chloride solution comprises nanocrystals and contains a higher content of Si with a Si:Ti ratio of 0.18(3). It is found that control of temperature and selection of Ti‐containing precursor play important roles in determining the crystal phase and crystallinity. A possible formation mechanism of porous crystalline TiO2is suggested. Characterization of these porous materials is performed by XRD, HRTEM, and nitrogen adsorption/desorption. SBA‐15‐templated mesoporous rutile TiO2exhibits a higher Li ion insertion capability than KIT‐6‐templated TiO2due to its larger surface area. Likewise mesoporous anatase TiO2:SiO2composite has a better photoactivity than bulk TiO2or TiO2‐loaded SBA‐15 for bleaching methylene blue.

AbstractPolyethyleneimine (PEI) is used as a scaffold for integrated top‐down/bottom‐up fabrication. In this synergistic strategy, patterned PEI surfaces are created using thermal nanoimprint lithography (NIL) using a sacrificial polystyrene (PS) overlayer. These imprinted surfaces act as versatile templates for assembling nanoparticles and dyes, with the amine groups of the PEI enabling electrostatic assembly, carbodiimide coupling, and dithiocarbamate attachment to the nanoimprinted features. The efficient assembly of particles and dyes is confirmed through fluorescence and atomic force microscopy. In these studies the PS overlayer serves two roles. First, the PS layer protects the PEI surface during the plasma‐etch removal of the residual layer of the NIL process. Second, the PS overlayer serves as a mask, enabling sequential functionalization of the sides and the tops of the PEI features.
Encapsulation of nanoparticles by polymerization compounding in a gas/solid fluidized bed reactor
Authors: Esmaeili Babak , Chaouki Jamal , Dubois Charles 
Published: July 2009

AbstractFor the first time, a fluidized bed reactor was used for encapsulating nanoparticles by the polymerization compounding approach using Ziegler–Natta catalysts. The polymerization reaction was carried out using a solvent‐free process in a gas‐phase reactor. This direct gas–solid reaction greatly simplified collecting the particles of interest after polymerization because none of the extra steps often found in encapsulation processes, such as filtering and drying, were performed in this work. The grafting of the catalyst to the original surface of particles was confirmed by X‐ray photoelectron spectroscopy. Micrographs obtained by transmission electron microscopy confirmed the presence of a thin layer of polymer, in the order of a few nanometers, around the particles. The thickness of this coating was affected by the operating conditions of the process. The characterization of the modified particles with electron microscopy also revealed that zirconia nanoparticles tend to be coated in an agglomerated state, whereas aluminum particles were mostly individually encapsulated by the polymer. In addition, the effects of temperature and pressure were studied on the encapsulation process and a kinetic analysis was presented based on the available models in the literature. © 2009 American Institute of Chemical Engineers AIChE J, 2009

Published: July 2009

AbstractWater‐soluble fluorescent conjugated polymers can be used as an optical platform in highly sensitive DNA sensors. Here we report a simple label‐free DNA sensor using poly(3‐alkoxy‐4‐methylthiophene) to recognize and detect different oligonucleotide targets related to the YMDD gene mutation of hepatitis B virus. The concentration of surfactant Triton X‐100, NaCl, the oligonucleotide capture probe and the oligonucleotide hybridization conditions have a great impact on fluorescence intensity. Under the optimum conditions, two types of oligonucleotide targets involving YMDD gene mutation of hepatitis B virus were successfully recognized. Moreover, there was a linear relationship between fluorescence intensity and the concentration of oligonucleotide target. The detection limit of the wild‐type hepatitis B virus target is 88 pmol L−1.

Authors: Tang Wanjun , Zheng Yingli 
Published: July 2009

AbstractA novel blue‐emitting phosphor of Eu2+‐activated NaMgPO4 was prepared by combustion‐assisted synthesis. Sodium dihydrogen phosphate and magnesium nitrate were used as the source of Na, P and Mg, respectively. The ratios of magnesium and phosphorus components that were dissolved into the combustion solution were changed from 1:1 to 1:1.3. Their effect on the crystallinities and photoluminescence spectra of the phosphor particles were investigated. The post‐heated phosphor particles had a broad excitation wavelength that ranged from 240 to 410 nm. The phosphor particles prepared from the combustion solution with a 1:1.2 ratio of magnesium to phosphorus had maximum emission intensity under ultraviolet excitation. The effect of doped Eu2+ concentration on the emission intensity of NaMgPO4:Eu2+ was also investigated.

Published: July 2009

AbstractBuyang Huanwu Decoction (BYHYD) is a classical traditional Chinese medicinal prescription that has been widely used for treating cerebrovascular illnesses for hundreds of years. In this study, a comprehensive analytical method has been developed for quantitative analysis of the major constituents in BYHWD. This method was based on high‐performance liquid chromatography coupled to a diode array and evaporative light scattering detectors (HPLC‐DAD‐ELSD) on a common reverse‐phase C18 column. HPLC coupled with on‐line time‐of‐flight mass spectrometry (HPLC‐TOF/MS) was additionally adopted to provide further validation for the constituents. It was found that 0.3% aqueous formic acid and acetonitrile was the optimum mobile phase for gradient elution. This method, which showed excellent precision and accuracy, was successfully applied to quantify the bioactive constituents in six BYHWD products. The validated HPLC‐DAD‐ELSD method, together with the HPLC‐TOF/MS analysis, provided a new basis for assessing the quality of traditional Chinese medicinal prescription consisting of many bioactive components.
