Avaliações de Funções de Pedotransferência para Solos Brasileiros
Authors: Costa Lorena Vila Bela , Soares Willames de Albuquerque 
Published: September 2021

Funções de Pedotransferência (FPT) são modelos matemáticos que estimam propriedades do solo de difícil medição por meio de variáveis mais acessíveis, gerando otimização de tempo e de recursos financeiros. Neste estudo, seis Funções de Pedotransferência, fundamentadas na equação de Van Genuchten (1980), foram analisadas para a predição da umidade volumétrica de solos brasileiros, com dados da base global Soil Data Task. Aplicadas para as pressões de 0, 0.01, 0.03, 0.10, 0.20, 0.50, 2.50 e 15.0 bar, os valores resultantes das equações foram comparados com as umidades volumétricas medidas por meio de cinco parâmetros estatísticos: índice de confiança, erro quadrático médio, razão dos desvios, eficiência de modelagem e coeficiente de massa residual. Das funções estudadas foi possível verificar que a função de B4v foi a que apresentou melhores resultados, enquanto que a de RB obteve o menor desempenho e que a eficiência de uma FPT está relacionada à dois fatores: semelhança entre os dados pedológicos do solo estudado e os utilizados no desenvolvimento da função e a quantidade de variáveis analisadas. Evaluations of Pedotransfer Functions for Brazilian SoilsA B S T R A C TPedotransfer Functions (FPT) are mathematical models that estimate difficult-to-measure soil properties through more accessible variables, generating optimization of time and financial resources. In this study, six Pedotransfer Functions, based on the equation of Van Genuchten, analyzed for the prediction of volumetric moisture of Brazilian soils, with data from the global database Soil Data Task. Applied for pressures of 0, 0.01, 0.03, 0.10, 0.20, 0.50, 2.50 and 15.0 bar, the resulting values of the equations were compared with the measured volumetric moistures through five statistical parameters: confidence index, mean square error, deviation ratio, modeling efficiency and residual mass coefficient. Of the functions studied it was possible to verify that the FPT proposed by Barros, with 4 parameters, was the one that presented the best results, while that of Rawls and Brakensied obtained the lowest performance. It has been observed that the efficiency of a FPT is related to two factors: a) similarity between the pedological data of the soil studied and those used in the development of the FPT, and b) the amount of variables analyzed.Keywords: Estimation; Soil Physical Properties; Soil Moisture Volumetric

A presente pesquisa apresenta como temática central a análise dos parâmetros morfométricos da bacia hidrográfica do rio Marapanim, Pará, como forma de subsidiar o planejamento ambiental da área. Estudos como estes se justificam pela importância regional das atividades econômicas realizadas nos municípios que compõem esta unidade como a dendeicultura em seu alto curso e predominância de agricultura familiar e pecuária em diversos trechos do médio e baixo curso. Pesquisas com esta finalidade são de fundamental importância para o conhecimento da dinâmica ambiental na Amazônia Oriental. A metodologia utilizada foi efetivada a partir da revisão de literatura, cálculo dos parâmetros com o uso do Arc Gis e elaboração do material cartográfico, além do tratamento das informações com a inferência de suas aplicações ao planejamento ambiental. Os resultados obtidos permitiram entender que a bacia do Marapanim apresenta baixo escoamento e maior taxa de infiltração, em função das suas características físicas, além de média a baixa tendência a enchentes, que ocorrem também pela relação das altitudes que variam de 0 a 70 metros e são consideradas de baixo impacto, indicando necessidade de implementação de ações que visem um planejamento relacionado ao ordenamento territorial e de uso dos recursos naturais. Morphometric Analysis of the watershed Marapanim River, Pará: study applied to environmental planning and landscape integrated analysis A B S T R A C TThis research has as its central theme the analysis of the morphometric parameters of the hydrographic basin of the Marapanim River, Pará, as a way to subsidize the environmental planning of the area. Studies like these are justified by the regional importance of the economic activities carried out in the municipalities that make up this unit, such as oil palm in its high course and the predominance of family farming and livestock in several sections of the medium and low course. Researches with this purpose are of fundamental importance for the knowledge of the environmental dynamics in the Eastern Amazon. The methodology used was carried out from the literature review, calculation of parameters using Arc Gis and preparation of cartographic material, in addition to the treatment of information with the inference of its applications to environmental planning. The results obtained allowed us to understand that the Marapanim basin has low runoff and a higher infiltration rate, due to its physical characteristics, in addition to medium to low flooding tendencies, which also occur due to the ratio of altitudes that vary from 0 to 70 meters and they are considered of low impact, indicating the need to implement actions aimed at planning related to territorial planning and the use of natural resources.Keywords: Hydrographic basin.

Resolving Office Establishment Dispute in Nigeria through Alternative Dispute Resolution Mechanism: An Evolving Regime
Authors: Adeuti Bosede Remilekun 
Published: September 2021

This paper examines contemporary issues in Office Establishment Dispute Resolution Mechanism in Nigeria. It explores strategic ways of resolving such office establishment dispute which has remained an intractable problem in Nigeria. The objective is to examine litigation challenges in settlement of this office dispute in Nigeria and other developing countries. This paper argues that adopting Alternative Dispute Resolution Mechanism in Office Establishment Dispute is not only a programmatic goal to be attained in the long term but rather an immediate obligation that is preferable to litigation in the court of law. The doctrinal research methodology will be used to examine the challenges in resolving office establishment dispute through alternative dispute resolution Mechanisms. This paper adopts an analytical and qualitative approach and builds its argument on existing literature works, which are achieved by synthesising ideas. Recommendations and suggestions are made based on research findings. This paper concludes that the era of jettisoning or sacrificing Alternative Dispute Resolution on the altar of inapplicability in resolving office establishment dispute is gone and the need to move with time with the practise which has been in existence in developed countries for decades.

Published: September 2021

Penelitian ini bertujuan untuk mengetahui kondisi ketahanan pangan rumahtangga petani terdampak gempa bumi. Penelitian ini juga mengamati strategi adaptasi rumahtangga petani dalam mengatasi situasi kerawanan pangan yang dialaminya. Akhir dari tujuan kajian ini adalah adanya rekomendasi pola intervensi yang perlu dilakukan oleh stakeholder agar tercapai ketahanan pangan rumahtangga petani.
Penelitian ini telah dilaksanakan di Kecamatan Kayangan Kabupaten Lombok Utara di 3 (tiga) desa yang terparah akibat gempa bumi dengan menggunakan metode riset eksploratif. Data dikumpulkan melalui metode survei (indepth interview, observasi dan FGD). Untuk menjawab tujuan penelitian dilakukan analisis persamaan Ketahanan Pangan (KP), Angka Kecukupan Energi (AKE), dan Pangsa Pengeluaran Pangan (PPP) serta analisis tabel untuk menunjukkan keragaan ketahanan pangan. Untuk menentukan faktor-faktor determinan yang mempengaruhi ketahanan pangan rumah tangga digunakan analisis regresi logistik.
Hasil penelitian menunjukkan distribusi rumah tangga petani menurut AKE sebagian besar tidak tahan pangan (51,43%) tetapi reratanya sudah tahan pangan (75,77% dari NKE), berarti terdapat disparitas kecukupan energi antar rumah tangga petani yang cukup tinggi. Berdasarkan analisis Pangsa Pengeluaran Pangan (PPP) teridentifikasi sebanyak 62,86 persen rumahtangga petani tergolong tidak tahan pangan dengan distribusi pada kriteria rumahtangga (rawan pangan sebesar 34,29 persen; kurang pangan sebesar 17,14 persen dan 11,43 persen tergolong rentan pangan), sedangkan rumahtangga tahan pangan sebesar 37,14 persen. Status gizi balita sebagian besar tergolong gizi baik yakni sebesar 70,83 persen, balita dengan status gizi kurang sebanyak 20,83% dan balita dengan status gizi lebih sebanyak 8,33%. Hasil analisis regresi logistik menunjukkan bahwa faktor determinan yang berpengaruh terhadap ketahanan pangan rumahtangga petani adalah: pengetahuan pangan dan gizi, ketersediaan pangan, dan pengeluaran pangan.
Direkomendasikan bahwa diperlukan: a) Proses edukasi tentang pola konsumsi pangan yang beragam dan berkualitas (gizi seimbang), b) Perlu dilakukan diversifikasi sumber penghidupan untuk mencukupi kebutuhan pangan dan non pangan dengan mengembangkan potensi sumberdaya alam seperti memaksimalkan pemanfaatan sumber air untuk mendukung kegiatan pertanian lahan kering, c) Melibatkan masyarakat khususnya petani dalam pelaksanaan proyek padat karya maupun pembangunan kembali sarana dan prasarana yang rusak akibat gempa bumi, d) Menumbuhkan wira usaha baru dikalangan pemuda berdasarkan pada potensi usaha yang bisa dikembangkan berdasarkan pada kearifan lokal.

Published: September 2021

The gas sensing properties of undoped Co3O4 and doped with Y2O3 nanostructures were investigated. The films were synthesized using the hydrothermal method on a seeded layer. The XRD, SEM analysis and gas sensing properties were investigated for the prepared thin films. XRD analysis showed that all films were polycrystalline, of a cubic structure with crystallite size of (12.6) nm for cobalt oxide and (12.3) nm for the Co3O4:6% Y2O3. The SEM analysis of thin films indicated that all films undoped Co3O4 and doped possessed a nanosphere-like structure.
The sensitivity, response time and recovery time to H2S reducing and NO2 oxidizing gases were tested at different operating temperatures. The resistance changed with exposure to the test gas. The results revealed that the Co3O4:6%Y2O3 possessed the highest sensitivity around 90% (at room temperature) and 62.5% (at 150 oC) when exposed to the reducing gas H2S and oxidizing gas NO2, respectively with 0.8sec for both recovery and response times.

Abstract:
The present study revealed the chromium toxicity and its health measures in L. rohita from the Yamuna river at Mathura- Agra region. Samples were taken in triplicate from both sites i.e. Vrindavan (Bihar ghat) and Agra (Renuka Ghat). The study was carried out on Four different organs (i.e. gills, muscles, liver, and kidney) of the fish sample. The sampling was done from Oct 2018 to January 2020. Chromium concentration in different organs of the fish was analyzed by Atomic absorption spectrophotometer(AAS). The average Cr concentration in gills was highest (9.64 mg/l) at the Mathura site followed byAgra sites (7.78 mg/l) for the month of April 2019. The concentration of Cr was highest in samples taken in the month of April 2019 and it was lowest in October 2018. The significantly high Cr concentration values were observed in the Mathura region than the Agra region for both seasons. In all samples, Cr concentration was above the standards stated by WHO except in the Kidney. In the present study, the bioaccumulation factor showed the chromium concentration in the tissues followed the order of gill > liver > muscle > kidney. HPI, MQI, and Pearson’s correlation coefficient analysis were also done in which HPI was observed very high and there was a positive correlation between all the samples.

Seasonal variations of indoor aerosols (PM2.5) in urban households of Jammu (J&K), India
Authors: Nishu  , Rampal Raj Kumar 
Published: September 2021

Indoor pollution is more harmful as people spend more than 90% of their time indoors getting enhanced chances of penetrating aerosols (PM2.5) deeply into the lungs. In the present investigation, an attempt has been made to study seasonal variations of indoor aerosols (PM2.5) in urban households of Jammu(J&K). in the northern region of India. The status of indoor aerosols (PM2.5) and their seasonal variations due to temperature and humidity conditions have been studied for the first time in urban households of Jammu (J&K). The two year study period (2017-2019.) revealed that all types of households of urban areas with non-wood fuel as well as wood fuel burning practices exhibited significantly (p<0.05) higher values of indoor PM 2.5 during summer season (74.36 µg/m3 and 156.46 µg/m3 ) followed by winter season (62.77 µg/m3 and 143.5µg/m3 ) and lower values during the rainy season (58.47 µg/m3 and 132.52 µg/m3 ). All these values were observed to be above the CPCB prescribed annual limit of 40 µg/m3, thereby exposing the residents to diseases of the respiratory and cardiovascular systems. The data generated in the present study will act as baseline data for future studies pertaining to indoor aerosols (PM2.5) as well as suggesting mitigation measures.

Authors: Divakaran Saratchandran A. , CT Anitha 
Published: September 2021

Ferulic acid is an abundant phytophenolic compound present in plant cell wall. Ferulic acid possess anticancer, antioxidant, and anti-aging properties. A simple, sensitive and reproducible spectrophotometric method has been developed for quantitative estimation of ferulic acid from selected plant materials such as rice bran, wheat bran and bamboo shoot. The blue coloured chromogen obtained after the reaction was measured at wavelength of 718 nm for ferulic acid against the blank reagent. The chromogen obeyed linearity over the range of 1?g/ml - 8?g/ml. An HPLC method was also developed for the estimation of ferulic acid from selected plant materials.
Huge Renal Angiomyolipoma in a Child with Tuberous Sclerosis Complex: A Diagnostic and Therapeutic Dilemma
Authors: Binti Syed Mudzhar Sharifah NurDurrah , Othman Mohd Yusran 
Published: September 2021

Tuberous Sclerosis Complex (TSC) is a rare neuro-cutaneous disorder that is associated with the development of benign hamartomas including renal angiomyolipoma (RAML). TSC associated RAML are usually asymptomatic, but it carries a life-threatening bleeding risk. We are sharing a case of a 5-year-old girl who was diagnosed to have TSC with associated subependymal giant cell astrocytoma, cardiac rhabdomyoma and autism. She presented with a history of worsening abdominal distension over 3 weeks duration and clinically noted to be pale with a ballotable left flank mass. Ultrasound and CT scan found to have multiple RAML in both kidneys with a huge mass on the left side. The mass represented a huge RAML (8cm) with aneurysmal formation with suspicion of intratumoral bleeding. The option of conservative management with mammalian target of rapamycin inhibitor followed with partial nephrectomy has been questioned with its life-threatening risk of bleeding and inability to do biopsy to rule out the possibility of renal cell carcinoma. Decision for nephrectomy was then made clearer following a MAG-3 scan which revealed only 11% differential function of the left kidney. She underwent a total left nephrectomy uneventfully and intraoperatively noted to have an enlarging lesion as compared to the previous imaging; 15cm in largest diameter. Histopathological finding was consistent with multifocal angiomyolipoma with intratumoral haematoma. Decision for nephrectomy in TSC-associated RAML need to be justified carefully in view of its risk of losing the contralateral kidney following the disease progression which may end up with life-long renal replacement therapy.International Journal of Human and Health Sciences Supplementary Issue-2: 2021 Page: S26
Gender-specific genital and subjective sexual arousal to prepotent sexual stimuli in androphilic men and gynephilic women
Authors: Micanovic Nina , Timmers Amanda D. , Chivers Meredith L. 
Published: September 2021

Marked differences have been found in men’s and women’s sexual response patterns, contingent upon their sexual orientation; androphilic (attracted to men) and gynephilic (attracted to women) men demonstrate greatest genital and self-reported arousal to their preferred stimulus type (a “gender-specific” response), whereas androphilic women do not, and findings for gynephilic women have been mixed. While there have been many investigations into gynephilic men’s and androphilic women’s (i.e., heterosexual men/women) sexual response, there has been less investigation into the specificity of sexual response of androphilic men and gynephilic women. Given the complex nature of sexual stimuli that are used in sexual response research, it is often unclear to what extent contextual cues (e.g., cues other than the sexual actor’s primary and secondary sex characteristics, such as physical attractiveness, sexual activity, etc.) influence participants’ sexual response patterns. As such, the current study examined genital, discrete self-reported, and continuous self-reported responses of androphilic men ( n = 22) and gynephilic women ( n = 10) to prepotent sexual features (stimuli thought to elicit automatic sexual arousal: erect penises and exposed vulvas), non-prepotent sexual features (flaccid penises and pubic triangles) and neutral stimuli (clothed men and women). Both samples exhibited a gender-specific pattern of genital, self-reported, and continuous self-reported sexual arousal. Similarly, all measures of sexual arousal were generally found to be greatest to “prepotent” sexual cues. Implications for understanding gender specificity of sexual response are discussed.
