Potensi air tanah sangat dipengaruhi kondisi geologi dan hidrogeologi, sehingga sebaran lapisan akuifer beragam dalam satu wilayah. Hal ini terjadi di wilayah Kecamatan Pakis Kabupaten Malang. Beberapa masih mengalami kesulitan memanfaatkan sebagai sumber bersih. Penelitian bertujuan untuk mengidentifikasi memetakan dangkal Pakis. Untuk menyelesaikan penelitian, dilakukan pengukuran dengan meto...

Introduction The deterioration process of inorganic materials induced by microorganisms, including glass, marble, concrete, sandstone, tufa, and metals, can cause various alterations such as crust formation on surfaces, change of hue, discoloration, and loss of materials, leading to structural damage (Figure 1). These severe problems are due to the excretion of aggressive metabolic products suc...

Calcerous tufa and sinter are among the most impressive natural spectacles in karst landscapes whose scientific aesthetic value is universally recognized. Being visually often very appealing they attract numerous visitors. At same time landforms extremely vulnerable can be seriously damaged even by minor interference. The challenge is, therefore, to protect calcerous heritage, communicate its v...

Stream periphyton has implications for ecosystem processes, yet little is known about its function in response to restoration efforts. In this study, we compared the taxonomic and functional composition of periphytic ciliates between restored unrestored (control) streams two different immersion periods identify species with indicator potential, ciliate traits that differ stream types, examine e...

The genus Hemerodromia in Thailand is revised and full descriptions and keys are provided for all 25 species. Twenty new species are recognised: H. alphalutea sp. nov., H. anisoserrata sp. nov., H. anomala sp. nov., H. attenuata sp. nov., H betalutea sp. nov., H. conspecta sp. nov., H. deltalutea sp. nov., H. deminuta sp. nov., H. demissa sp. nov., H. epsilutea sp. nov., H. etalutea sp. nov., H...

Protozoan parasites of the phylum Apicomplexa contain three genetic elements: the nuclear and mitochondrial genomes characteristic of virtually all eukaryotic cells and a 35-kilobase circular extrachromosomal DNA. In situ hybridization techniques were used to localize the 35-kilobase DNA of Toxoplasma gondii to a discrete organelle surrounded by four membranes. Phylogenetic analysis of the tufA...
