The aims of this work were to monitor the dissipation dynamics of the organophosphate insecticides applied to corn grains stored in supervised experiments, establish the dissipation dynamics and determine the minimum period post application necessary to comply with the established commercial standards. The insecticides dichlorvos (DDVP), hlorpyrifosmethyl+deltamethrin (CPM) and pirimiphos-methyl (PMM) were applied to maize grains, which were then stored for 120 days. The samples were processed and extracted using the QuEChERS technique and the pesticide residues were identified and quantified by gas chromatography-mass spectrometry. Deltamethrin residues were not analized. After 90 days of storage, more than 80 % of the initial residue had been degraded, and after 120 days the residues were below the detection limit (LoD). DDVP, CPM and PMM residues followed a first order degradation dynamics [Ct = C0×e(-kt)], with k values of 0.384, 0.025 and 0.020 and estimated half-lives of 1.8, 27.7 and 34.7 days, respectively. These results show that at recommended dosages, the insecticides CPM and PMM are safe for use on stored maize grains; DDVP results provide additional evidence further reasserting its prohibition, which dates back to 2018.

Vicia villosa es un recurso forrajero potencial en áreas marginales asociado con su resiembra natural y sus atributos agronómicos. Los objetivos del trabajo fueron registrar y analizar el patrón de absorción de agua, determinar el porcentaje de germinación, estimar los parámetros de tiempo hídrico y establecer la composición isotópica de 13C y 15N de la plántula cuando Vicia villosa germina en condiciones de estrés hídrico y salino. Los ensayos para determinar el patrón de absorción y la respuesta a la germinación se realizaron según el tratamiento: control (agua destilada) y soluciones con potencial agua (Ya): -0,3; -0,6; -0,8; -1 y -1,2 MPa. Los osmolitos fueron poliethylene glicol (PEG) y cloruro de sodio (NaCl). La composición isotópica de la materia orgánica total (MOT) se determinó en condiciones control, -0,8 y -1,0 MPa. La absorción de un 125 % de agua desencadenó la germinación. Se estimó que con Ya de -0,6 y -0,8 MPa se alcanzaría un 90 % de germinación en estrés hídrico y salino. Los tratamientos de PEG y NaCl mostraron un enriquecimiento en 13C y un empobrecimiento en 15N respecto al control. Los resultados experimentales indican que esta especie es más tolerante a la salinidad que al estrés hídrico.

Background: Hand, foot mouth disease (HFMD)is caused by a virus and commonly affects children five years or below. However, the determinants of the associated factors with preventive behaviour among parents are still lacking. This study aims to assess the range of preventive behaviour towards HFMD among parents in Selangor, Malaysia.
Materials and Methods: A cross-sectional survey was conducted using a three-stage cluster sampling method. The associations between independent variables and preventive behaviours were assessed with multivariate regressions.
Result: In total, 556 parents completed the survey. The majority of the parents had good preventive behaviours towards HFMD. Age, gender, income, perceived susceptibility and the perceived benefit was associated with preventive behaviour.
Conclusion: Although, the preventive behaviour of HFMD among parents is crucial, however, it is influenced by parents own perceptions. The strategies to enhancing the parent’s perception are needed to increase the preventive behaviour towards HFMD infection.

Matematika merupakan alat untuk memberikan cara berpikir, menyusun pemikiran yang jelas, tepat, dan teliti. Hudojo (2005) menyatakan, matematika sebagai suatu obyek abstrak, tentu saja sangat sulit dapat dicerna anak-anak Sekolah Dasar (SD) yang mereka oleh Piaget, diklasifikasikan masih dalam tahap operasi konkret. Siswa SD belum mampu untuk berpikir formal maka dalam pembelajaran matematika sangat diharapkan bagi para pendidik mengaitkan proses belajar mengajar di SD dengan benda konkret.
Heruman (2008) menyatakan dalam pembelajaran matematika SD, diharapkan terjadi reinvention (penemuan kembali). Penemuan kembali adalah menemukan suatu cara penyelesaian secara informal dalam pembelajaran di kelas. Selanjut Heruman menambahkan bahwa dalam pembelajaran matematika harus terdapat keterkaitan antara pengalaman belajar siswa sebelumnya dengan konsep yang akan diajarkan.

Silencing the Radical Black Feminist
Authors: Vesuna Alexander 
Published: February 2022

In their work Left of Karl Marx: The Political Life of Black Communist Claudia Jones, Carol Boyce Davies works to rescue Claudia Jones from obscurity and bring the brilliant intellectual back into dominant historical discourse. The Radical Black Feminist was erased from the history books because her intellectual thought posed a threat to the capitalist order. Claudia Jones spent her life working as a journalist allowing her intellectual thought to be brought to the masses in an attempt to build the consciousness of the people. She was key theoretician in the CPUSA and as a Black Radical Feminist Jones stood at the vanguard of revolutionary political thought working to push Marxism further left to account for the intersections of race, gender, and class. Therefore, leftist and Marxist political thought needed to be pushed further left to recognize the triple oppression that Black Women faced. Claudia Jones possessed a unique ability to speak across difference bringing different groups of people together. Her anti-capitalist political thought and this ability to bring people together was seen as a threat to the wealthy elite and the status quo, leading to her eventual deportation to Britain. This piece will work to highlight the life and contributions of Claudia Jones that has been given new life by Carol Boyce Davies.

This experiment was conducted to explore the effect of various types of coagulants on the chemical and microbiological quality of cheese made from fresh milk. Fresh cheese was manufactured using four different coagulants; microbial rennet (0.7%), lactic acid (1.5%), papaya latex (5 drops in 100 mL water) and calf rennet (100 g calf abomasum soaked overnight in 1000 mL mixture of water and milk in 3:1 ratio and then filtrate) under laboratory condition and analyzed for cheese yield, proximate composition, acidity, pH and coagulation time. In addition, standard plate count and coliform count was also performed. Result revealed that using microbial rennet as coagulant gave the maximum yield of cheese (225 g/Kg milk) followed by calf rennet and lactic acid, and papaya latex had the minimum value (215g/Kg milk) in this regard (p=0.013). Microbial rennet took the lowest time (22 min) to coagulate the milk which was 14-34 min less than that of the other coagulants, and lactic acid had the slowest (54 min) coagulating action in cheese manufacturing process (p=0.000). In addition, cheese that are manufactured by microbial rennet and calf rennet were superior in terms of chemical composition compared to the cheese in which lactic acid and papaya latex was used as coagulant (p=0.000-0.047). But the calcium concentration was found maximum in papaya latex cheese. Acidity was found highest in lactic acid cheese and papaya latex cheese had the highest pH value. On the other hand, standard plate count and coliform count was found highest in cheese coagulated by lactic acid, where microbial rennet cheese had the lowest count, and the microbial count of other two cheese was intermediate of them (p=0.000-0.001). Overall, microbial rennet, lactic acid, papaya latex, and abomasum rennet could be used to make cheese successfully, however, with a preference to microbial rennet.
