Copper and Zinc Contents in Urban Agricultural Soils of Niger State, Nigeria

Study of the Cu and Zn contents in urban agricultural soils is paramount in order to assess concerning the possible potential risks they may pose at high concentrations to life and environment through the food chain. Levels of Cu and Zn in soil samples collected from cultivated farmlands in the vicinity of abandoned industrial sites at two cities of Minna and Bida in Niger State, were determined using flame atomic absorption spectrophotometry technique. The concentrations were in the following ranges; 12-89mgCukg-1 and 2.8-41mgZnkg-1 for Minna and 2.4-6.5mgCukg-1 and 0.57-36mgZnkg-1 for Bida. The accumulation of Cu in Minna cultivated farmlands was apparent, with a mean Cu content of 24 + 22ppm, which was almost five times that of the control soils, but other mean values were similar to the soilbackground average contents. Soil properties were also analysed, andobtained results for the cultivated farmland soils of the two cities were of the following ranges: - pH (5.0-7.5), Organic carbon (0.36-2.5)%, sand (46.4- 94.2)%, silt (2.3-20.0)% and clay (1.8-33.6)%. Cu and Zn positively correlated among themselves, Cu correlated with clay content and Zn correlated with pH and organic carbon in all the soils. Keywords: heavy metals, accumulation, environment, cultivated farmlands, abandoned industrial sites

Transmissible venereal tumor and anaplasmosis in a domestic dog

This paper reports a case of a transmissible venereal tumor and anaplasmosis in a domestic dog. A 2-year-old, 7.1 kg, black and white domestic female dog was presented to the clinic for examination after being rescued. Physical examination revealed Rhipicephalus sanguinis infestation and vaginal swelling with nodules approximately 5 mm in diameter. A complete blood count indicated leukocytosis, neutrophilia, and eosinophilia. Decreased hemoglobin, mean corpuscular hemoglobin concentration, and platelet values were observed. Blood biochemistry test results showed decreased total protein levels. Vaginal nodule cytology results were consistent with a transmissible venereal tumor. The dog was diagnosed with a transmissible venereal tumor and anaplasmosis. Treatment included doxycycline antibiotics, vincristine chemotherapy agents, fu fang herbal supplements, fluralaner anti-flea and tick medication, cazitel antihelmintics, Kalvidog supplements, and medicated shampoo for skin condition improvement.Makalah ini melaporkan kasus tumor kelamin menular dan anaplasmosis pada anjing peliharaan.

Evaluation of Kinetic Models of Copper and Lead Uptake from Dye Wastewater by Activated Pride of Barbados Shell

Abstract Pride of Barbados shell was effectively used as a raw materials for the production of activated carbon with HNO 3 as an activating agent using twostep process. Batch adsorption was used in interacting the dye wastewater with activated carbon within 30-150 minutes contact time. The maximum adsorption of Cu and Pb were 96.63% and 85.55% at 150 minutes and 30 minute contact time respectively. The result was found to match well with pseudo second-order compared to pseudo first-order, Natarajan and khalaf first order and Elovich model tested. Therefore, activated pride of barbados shell could be employed as an adsorbent in removing Cu and Pb from similar wastewater and aqueous solution

Nutritional value, micronutrient and antioxidant capacity of some green leafy vegetables commonly used by southern coastal people of Bangladesh.

Southern coastal people of Bangladesh are highly vulnerable to food insecurity and malnutrition due to coastal flooding, deforestation and increased soil salinity. A number of green leafy vegetables are found in the southern coastal belt being traditionally eaten as daily basis by local people. But they are unaware of nutritional and medicinal use of these vegetables. To contribute to their wider utilization, five common vegetables namely Hibiscus sabdariffa, Trianthema portulacastrum, Diplazium esculentum, Heliotropium indicum L. and Hygrophila auriculata were selected for analysis of nutritional proximate, micronutrients and antioxidant potential. Nutritional properties were analyzed in terms of moisture, pH, protein, lipid, ash, fibre, minerals and carbohydrate. Total flavonoid, tannin and antioxidant capacity were evaluated using established protocols. The results demonstrated that collected plants are rich in carbohydrate, fibre, proteins, moisture and ash content but low in lipid content. The mineral elements were high with remarkable amount of Na (19.9-21.5 mg/gm), K (7.9-13.5 mg/gm) and P (1.0-1.8 mg/gm). All the samples were found to have considerable amount of flavonoid (90.6-144.5 mg QE/gm) and tannin content (26.8-57.2 mg GAE/gm). The IC50 value of DPPH and superoxide radical scavenging was the lowest for H. indicum (37.1 and 83.4 μg/ml, respectively) whereas T. portulacastrum possessed high reducing power (IC50 53.7 μg/ml). Among the five investigated species, T. portulacastrum and H. indicum were found to have good nutritional and antioxidant properties, thus can be promoted as a significant source of nutritional and antioxidant food supplements

Les Politiques des Réformes Administratives en République Démocratique du Congo (1990-2010)

Since multiple decades, the reform of the Congolese public administration figures on the agendas of both the national authorities and the international institutions. These reforms that are currently taking place are the expression of the phenomena of import and replication (transposition) which are expected to provide elements of innovation and progress in administrative governance practices. In this regard, the substantive questions intended to capture what reformist theory underpins these reforms, for which administrative change and societal environment it serves, or more tersely which reform for what kind of development? The answer to this question leads to decrypt in-depthreform policies to determine their actual intelligibility and real significance, in order to discover what they are and what they are not, whatthey can provide as concrete results and what they cannot provide, and why. This quest requires a strategic analysis method supported by appropriate investigation tools including living and nonliving research techniques. The policies of administrative reformsinitiated and implemented in the Democratic Republic of the Congo illustrate to what extent the model of political reform that is implemented has its limits and is inefficient due to the unresponsiveness to and little incentive for the political context and local culture. In this way, this model raises the problem of the effectiveness of development aid andassistance in Africa and Congo, especially with regard to the question of development cooperation , which remains primarily dictated by external supply and not by the internal demand. Its application is therefore misaligned, poorly adapted and poorly humanized under its extraneous character. From the perspective of the donors and the multi-donors, the question of reforms is perceived as d to thequestion a mere technical concern, while in reality it requires the inclusion of the socio-political dimensions. Between the classic paradigm or dominant exogenous development type and the introvert or endogenous paradigm, we must choose the latter because it is auto-centred and therefore adapted to the local context and circumstances.nrpages: 304status: publishe

Studi Kualitatif Eksploratif: Gambaran Pola Perilaku Kepatuhan Diet Pasien Diabetes Mellitus Tipe 2 Di Puskesmas Kendal Kerep Kota Malang

Diabetes Mellitus (DM) merupakan suatu penyakit metabolik yang disebabkan kurangnya produksi insulin atau gangguan pada fungsi insulin. Diperkirakan sekitar 170 juta orang menyandang diabetes pada tahun 2000, dan angka ini akan meningkat hingga sekitar 366 juta orang pada tahun 2030 di seluruh dunia. Penatalaksanaan DM dititikberatkan pada 4 pilar, yaitu: edukasi, terapi gizi medis, latihan jasmani dan intervensi farmakologis. Penelitian ini bertujuan untuk mengetahui secara mendalam gambaran pola perilaku pasien DM terhadap kepatuhan diet. Penelitian ini merupakan penelitian kualitatif eksploratif dengan pendekatan studi kasus. Informan kunci yang kriterianya sesuai dengan kriteria inklusi penelitian berjumlah 4 orang, ditambah 3 orang anggota keluarga dan 1 orang Ahli Gizi Puskesmas. Pemilihan informan ini menggunakan metode purposive sampling. Pengumpulan data dilakukan pada natural setting dengan menggunakan teknik wawancara mendalam. Hasil analisis dari wawancara mendalam menunjukkan bahwa pola perilaku pasien terhadap sakit dan penyakitnya tidak tampak berbeda dengan orang sehat kebanyakan. Tingkat pengetahuan tidak selalu berbanding lurus dengan motivasi perilaku seseorang. Perubahan perilaku tergantung penerimaan dari masingmasing individu dan faktor-faktor lain yang mempengaruhi seperti faktor lingkungan. Motivasi dari keluarga secara tidak langsung dapat memberikan dampak untuk perubahan perilaku pasien secara bertahap. Selain itu motivasi dari tenaga kesehatan dan kolaborasi antar tenaga kesehatan juga diperlukan untuk peningkatan kepatuhan
