Welcome to Clacc.net!

We are a group of fellows and international experts working on adaptation to climate change for least developed countries. Our aim is to strengthen the capacity of organizations in poor countries and support their initiatives in sustainable development through the network of fellows. We operate in 15 countries in the South, 12 in Africa and 3 in South Asia. 

As a group, we believe that adaptation to climate change goes hand in hand with sustainable development. Our team of southern experts comes from a wide variety of fields, including microbiology, wildlife conservation, natural resources, agriculture, hydrology and anthropology. Our multi-disciplinary approach helps us bridge the gaps between climate change and development.  Our network is also advocate for adaptation during international conferences such as the COP and with local governments.

Anteroposterior radiograph shows extensively calcified large pelvic mass. Calcifications are seen in approximately one third of all synovial sarcomas. canadian viagra online View larger version: in this window in a new window download as powerpoint slide fig. 1b. —12-year-old boy with synovial sarcoma who presented with palpable pelvic mass. Contrast-enhanced axial ct scan of pelvis shows unusual primary location of synovial sarcoma (arrows). Mixed cystic and solid appearance of tumor is common in synovial sarcoma and may be due to hemorrhage, necrosis, or both. B = bladder.

Sagittal proton density—weighted mr image (tr/te, 3000/17) shows 4-cm well-defined cystic soft-tissue mass (m) adjacent to semimembranous tendon (arrows) of left knee. Most synovial sarcomas, like one shown here, arise near large joints in lower extremity and involve tendon sheaths, bursae, or joint capsules. Because masses are often well defined and frequently have cystic appearance, synovial sarcoma is malignant lesion most commonly misdiagnosed as benign on mr imaging.

Contrast-enhanced t1-weighted axial mr image (tr/te, 710/15) shows inhomogeneously enhancing mass (arrows) adjacent to right hip. Many synovial sarcomas, like this one, appear as heterogenous multiloculated masses with internal septations and may contain fluid—fluid levels. Note well-defined margins of mass, characteristic of synovial sarcoma seen on mr images.

Case illustrates unpredictable nature of malignancy. View larger version: in this window in a new window download as powerpoint slide fig. 4a. —9-year-old girl with metastatic synovial sarcoma.

Coronal short tau inversion recovery mr image (3825/30; flip angle, 140â°) obtained after surgical resection and radiotherapy of primary tumor shows genu valgus deformity caused by effects of therapeutic radiation. Although radiation therapy provides excellent local control of microscopic residual disease, it may result in substantial growth disturbance when applied near physeal plate of growing bone. Note also bright signal in bones of knee, likely due to radiation-induced ischemia, osteonecrosis, or both.
